There are many forms of grouting pipes that can be improved and applied. Although the engineering pipeline system is very complex, any complex pipe system can be divided into several relatively simple individual pipe sections through the setting of fixed pipe racks. When selecting the corrugated grouting pipe, the deformation compensation of the pipe system can be determined according to these relatively simple pipe sections, so as to select the grouting pipe.In limestone area, the punching is not good, and it is difficult to sink the reinforcement cage. When the grouting pipe is deformed and blocked by unconventional means, the pipe is blocked due to the workers&#; carelessness and falling into small concrete blocks. The deformation and blockage of the grouting pipe bring great difficulties to the detection work, and even can not be detected. Therefore, effective measures should be taken to pass the pipe to ensure the smooth progress of ultrasonic inspection. Generally, there are three methods for passing the pipe: stabbing the grouting pipe with thick and long reinforcement flushing and pigging with high-pressure water, and using a drill with a small drill to clean the hole.Estonia,The advantages of the grouting pipe are as follows: The embedded grouting pipe can be injected with water by on-site pressure to confirm the water tightness of the joint. Grouting is required only when the joint leaks water. performance of grouting pipe the grouting pipe is light in weight has strong bite force with soil or gravel, is acid-base resistant, corrosion-resistant, aging resistant and easy to construct. It has high tensile strength (- times higher than that before stretching) and low elongation (only % - % of that before stretching). It is easy to cut and connect on site (polyethylene rope or connecting rod can be used for connection), and it can also be overlapped (the grouting pipe with overlapping buckle has been developed and can be connected without other materials), and the bending effect during construction is small. However, the grouting pipe has low hardness, poor mechanical damage resistance, and mechanical scars such as scratches and crushed stones will produce stress concentration, which will reduce the overall mechanical properties of the grouting pipe and the grouting pipe.Sosan, Classification of grouting pipe grouting pipe the grouting pipe is a plane mesh material of grouting pipe with certain flexibility. The main raw material is polyethylene grouting pipe. It is extruded into thin sheets by a grouting pipe extruder, and grouting pipe processed by seamless steel pipe is generally rare in the market. The reasons are as follows: first, in terms of price, the cost of grouting pipes made by welding is relatively low, which is easy for purchasers to accept. The cost of domestic products made of spiral steel pipes and seamless steel pipes is too high. Second, in terms of processing technology, welded pipes are relatively easy to process, and the equipment required is relatively simple. If spiral steel pipes and seamless steel pipes are processed, the process is relatively complex. Manufacturing process and characteristics of clamp down grouting pipe clamp down grouting pipe is a kind of grouting pipe. Because only professional hydraulic clamps are required for connection, it is also commonly called clamp down grouting pipe. The clamp grouting pipe has the following characteristics: the connection of the grouting pipe is simple, as long as the hydraulic clamp is required for connection. The grouting pipe has joints at both ends of the clamp type grouting pipe, which avoids the possibility of loosening and has good seismic resistance. Several common failures in the installation of grouting pipes always have many problems when using grouting pipes for work. In order to enable everyone to provide production to the factory normally, we have specially summarized the following failures that will occur when using grouting pipes. If you have problems in the following examples, you will know how to solve them The first point is that if the joint, nozzle or bottom of the grouting pipe is not tightly sealed it will be blocked by cement slurry during construction. At this time, we need to know that it is caused by the thin material selected. The above two points are common problems in the installation of grouting pipes that are not suitable for the current location. We&#;d better remember these points of attention it is OK to check the sealing The second point is that the joint is misaligned or deformed during installation. At this time, so that when they occur in the future, we will know how to deal with them to ensure a quick solution! The grouting pipe joint or the pipe orifice and the pipe bottom are not sealed tightly, so please bring in mud or cement slurry during the construction process to block the pipe: during the installation and grouting of the grouting pipe, causing the dislocation and deformation of the grouting pipe joint or the deformation of the pipe wall. The main reason for this is the selection of thin-walled grouting pipes.It is laid in the soil, and through the bite and interlock between the grouting pipe mesh and the soil, it forms an efficient stress transmission mechanism, so as to reduce the local failure stress and improve the service life of the project. The convex joint steel plastic grouting pipe is an upgraded product of the ordinary steel plastic grouting pipe, which changes the shortcomings of the ordinary grouting pipe, such as the small peeling force of the joint (n) the easy cracking of the welding point, the difficulty of construction, and the reduction of the role of side displacement prevention. Due to the change of material ratio and construction technology, the peeling force of the welding joint is between N and N, which effectively changes the above shortcomings of the traditional steel plastic grouting pipe. Because of the protruding joints at the welding position, it is called convex joint steel plastic grouting pipe, and its academic name is node reinforced steel plastic grouting pipe. The steel plastic grouting pipe is made of high-strength steel wire (or other fibers) through special treatment, polyethylene (PE) and other additives, and is extruded to form a composite high-strength tensile strip. If the surface is rough embossed, it is a high-strength reinforced geotextile. This single belt is woven or sandwiched at a certain distance longitudinally and horizontally and is formed by welding its junction with the fusion welding technology of special reinforcement bonding. The grouting pipe is set out from the inner ring tap in the vertical setting out state, and the drawn out pipe forms a spring shape and stretches automatically. Takeout direction: the spiral direction of the spring shape after takeout is consistent with the twisting direction of, otherwise fried dough twist or disorder will occur.

Appropriate measures shall be taken to prevent surface water, curing water and garbage from falling in. When necessary, a sump shall be set near the post cast strip of the base plate in combination with the design of the basement plane drainage system to facilitate the final cleaning before the grouting pipe is cast. When advance water stop is not used, a sump shall be set, which can be set in the basement according to the above method or set outdoors as a temporary facility. Usually, and there are many methods for the grouting pipe to stop water in advance. It should be noted that the design unit should participate in the review of the construction organization design of the basement, so as to determine a complete implementation scheme of advanced water stop before the excavation of the foundation pit and the pouring of the cushion. Otherwise, the design modification requirements will be put forward only when problems are found in advance water stop during construction, which will affect the integrity and rationality of the whole water stop scheme. Curing The concrete components shall be covered and moisture cured within h after pouring. The time of concrete curing by watering shall not be less than days for the concrete mixed with Portland cement, ordinary portland cement or slag Portland cement; For the concrete mixed with retarded admixture or with impermeability requirements, it shall not be less than degrees. The cured concrete shall be covered with plastic cloth, and all exposed surfaces shall be tightly covered, and condensed water shall be kept in the plastic cloth.The existence of grouting pipe mesh restricts the lateral movement of soil. The lateral sliding deformation of the soil is limited by friction and interlocking engagement between the grouting pipe and the sand particles and the passive resistance of the sand particles to the grouting pipe, forming a good interlocking effect, so that the soil has better overall shear strength and bending stiffness.Finance Department, the types of grouting pipes are relatively complete now, different types of grouting pipes are selected to convex joint grouting pipes and plastic tensile grouting pipes for railway. For different road construction environments, which can not only ensure the quality of the road but also save the cost. So what kind of application effect can the grouting pipe achieve in highway maintenance? The grouting pipe manufacturer will take you to have a look.However, not all grouting pipe products can achieve this effect. Some inferior grouting pipe products not only fail to achieve the expected effect in use but also have problems such as low grouting efficiency, pipe burst and pipe bending, which seriously affect the grouting effect of the grouting pipe and the progress of the whole project. The quality of grouting effect comes from the selection of high-quality grouting pipe products. Shengpeng grouting pipe is a good choice for you to choose grouting pipe products because of its high strength, awesome, simple connection and high cost performance! Grouting pipe the grouting pipe is a kind of geosynthetic material formed by ultrasonic welding, which is composed of a steel plastic composite reinforced belt (built-in high-strength carbon spring steel wire (stress material) and wrapped with polyethylene resin (protective material) and arranged at right angles to the plane longitude and latitude. It is a comprehensive product of existing rigid reinforcement (flat steel strip, ribbed steel strip, galvanized steel strip, stainless steel strip, reinforced concrete strip, etc.) and flexible reinforcement (polypropylene strip, plastic grouting pipe, warp knitted grouting pipe, etc.). Because of its high tensile strength, low elongation (≤ %), small creep, and strong interlocking and occlusive effect on the soil, it can effectively treat the soft soil foundation, restrict the lateral displacement of the soil, overcome the uneven settlement of the soil, greatly enhance the bearing capacity of the foundation and improve the overall performance of the foundation; It can be widely used in road engineering, railway engineering, retaining structure, the following treatment principles must be followed: when it is the first pile of a certain bridge, core drilling detection must be carried out; when it is not the first pile of a certain bridge, the construction unit shall apply for changing the detection method The low strain reflection wave method or high strain strain strain measurement method shall be used and signed by the supervisor&#;s representative and the person in charge of quality supervision before implementation; In case of pipe blockage of a bridge for many times, core drilling inspection shall be carried out in due time. Other uses of grouting pipe introduction the grouting pipe of pile foundation refers to the steel pipe that needs to be embedded when testing the quality of pile foundation. Generally, it is bound in the reinforcement cage and lowered into the hole together with the reinforcement cage before pouring concrete! There are many reasons for the grouting pipe to gamble on the pipe, most of which are due to the leakage of slurry caused by the pipe joint not being welded well during processing, and also due to the pipe mouth not being closed well and falling debris, the pipe is blocked! To put it bluntly, the pipe is blocked by sundries! The role of the grouting pipe is to inject clean water into the grouting pipe and put the transducer into the grouting pipe for testing when the integrity of the pile foundation is tested by ultrasonic wave. If the grouting pipe is blocked, the transducer can not be put in, or can not be placed at the bottom of the pile, so it is impossible to comprehensively test the whole pile and judge the quality of the pile foundation!

If any crack is found, it shall be repaired in time, otherwise when the joint is deformed and subjected to water pressure, the ability of the grouting pipe to resist external forces will be greatly reduced. When positioning the grouting pipe, it must be kept flat at the interface, and the grouting pipe must not be allowed to roll or kink. If it is found that there is no twist, it should be adjusted in time. When casting and fixing the grouting pipe, the deviation of the grouting pipe shall be prevented, so as not to shorten one side and affect the water stop effect. When pouring and tamping the concrete, it must be vibrated sufficiently to prevent the poor combination of the grouting pipe and the concrete from affecting the water stop effect. The grouting pipe joint must be well bonded. If the construction site conditions are available, the method of hot vulcanization connection can be used.?Free consultation,Appropriate measures shall be taken to prevent surface water, curing water and garbage from falling in. When necessary, a sump shall be set near the post cast strip of the base plate in combination with the design of the basement plane drainage system to facilitate the final cleaning before the grouting pipe is cast. When advance water stop is not used, a sump shall be set, which can be set in the basement according to the above method, or set outdoors as a temporary facility. Usually, we use the waterproof scheme between the grouting pipe and the water surface or before, and there are many methods for the grouting pipe to stop water in advance. It should be noted that the design unit should participate in the review of the construction organization design of the basement, so as to determine a complete implementation scheme of advanced water stop before the excavation of the foundation pit and the pouring of the cushion. Otherwise, the design modification requirements will be put forward only when problems are found in advance water stop during construction, which will affect the integrity and rationality of the whole water stop scheme.Most of the grouting pipes on the market are meters in stock, and some construction sites have different requirements, so there are few in stock. In fact,EstoniaGrouting small conduit and advance anchor rod, they have different styles and different names. There are cross pair perforations and plum blossom holes. There are about holes in the whole pipe, which can be described as a hundred holes. One end of this pipe has plugs, sharp and round, depending on the customer&#;s requirements. The other end is welded with reinforcing bars from the pipe section to prevent the pipe section from tearing. This kind of pipe is called steel flower pipe. Steel flower pipe is generally used for high-speed maintenance grouting to protect mountains and prevent landslides. Holes are drilled on the steel flower pipe, which is more conducive to the penetration of cement mortar liquid into the rock and soil mass of the rock stratum and to the anchoring. In order to prevent the hole from being blocked by stones, sometimes the design requires reinforcement to protect the hole. After grouting, the pipe orifice must be closed, so as not to let the grouting liquid flow out. The general classification of grouting pipe models can be divided into ordinary standard connection and pipe hoop connection according to their different connection methods.In the process of using the acoustic pipe, it is necessary to have a detailed understanding of its installation method, so that it can be used normally and improve the application quality of the grouting pipe. In the process of installing Jiangsu acoustic measuring tube, we should pay attention to the orientation of the installation hole. As long as the device is installed in a correct hole, the Jiangsu acoustic tube can be used normally in the process of application, and the service life of Jiangsu acoustic tube can be improved. This is also the most important factor in the process of application in the future. If the hole fault is bragged about in the process of the device, the resistance of Jiangsu acoustic pipe will appear in the process of application, resulting in its damage. There is a great relationship between the accuracy of the hole and the quality after construction. In the process of construction, it is necessary to use the device according to the planned paper so that it can be used normally and improve the quality of use.In the process of application, because there will be many Jiangsu acoustic measurement pipes in the process of construction. In this way, the phenomenon of uneven stress will be formed. In the process of application, the phenomena of conflict and unusable will be formed. In order to prevent the phenomenon of surrounding each other, it is necessary to pay attention to the method of the device in the process of the device,EstoniaAdvanced small conduit processing, so that it can be used normally. The grouting pipe manufacturer introduced that the product quality of the grouting pipe is relatively stable, and when the mold is finalized, it is not easy to show defects. Most of the defects of the grouting pipe appeared in the trial production period, and most of them were formed due to the unreasonable planning structure of the mold. The grouting pipe manufacturer will briefly introduce the treatment methods of defects as follows: wrinkle appearance and treatment methods. The so-called wrinkle refers to that there is a convex edge on the circular arc surface of the grouting pipe, and there is a concave appearance on the adjacent side. This kind of wrinkle is mostly in the shape of sharp ridges, some of which are straight to the nozzle, and often occur symmetrically at both ends of the center line, in the shape of 'eight'. Chengdu grouting pipe manufacturers mostly occur on the inner arc surface, and some occur on the outer arc surface.Estonia,Disposal method: the grouting pipe shall be shortened according to the specification.Several common failures in the installation of grouting pipes always have many problems when using grouting pipes for work.

The grouting pipe joint or the pipe orifice and the pipe bottom are not sealed tightly, so please bring in mud or cement slurry during the construction process to block the pipe: during the installation and grouting of the grouting pipe, the rebar is distorted or collided, causing the dislocation and deformation of the grouting pipe joint or the deformation of the pipe wall. The main reason for this is the selection of thin-walled grouting pipes. Classification of grouting pipe grouting pipe the grouting pipe is a plane mesh material of grouting pipe with certain flexibility. The main raw material is polyethylene grouting pipe. It is extruded into thin sheets by a grouting pipe extruder, and then punched with regular holes. Then it is made by directional stretching under the control of heating. It can be divided into unidirectional grouting pipe and bidirectional grouting pipe according to the different stretching modes when it is manufactured.
