It is required to ensure that at least one embedded reinforcement is firmly welded with the anchor ring of maolehan grouting pipe within every meter along the joint direction. The quality of XF type grouting pipe should be carefully checked. If deformation or inconsistent spacing between two steel beams is found, it should be repaired. If necessary, the steel beam spacing of maolehan grouting pipe shall also be adjusted according to the ambient temperature during installation. XF type grouting pipe device shall be slowly put into the groove, so that the center line of the joint coincides with the center line of the actual reserved joint, and the deviation shall not exceed mm. Meanwhile, the inner edge of the steel side beam shall be kept vertical. After the XF grouting pipe is in place, the top surface of its steel beam shall be adjusted according to the longitudinal, transverse slope and elevation to be ~ mm lower than the adjacent asphalt concrete pavement and shall not exceed the pavement elevation.It is required to ensure that at least one embedded reinforcement is firmly welded with the anchor ring of maolehan grouting pipe within every meter along the joint direction.

When the reinforced soil is loaded, the grouting pipe has a high bond with the soil, showing better tensile performance. The tensile stress of the soil is transmitted to the grouting pipe, making the reinforced soil a tensile member, which can change the stress from the vertical direction to the horizontal direction, spread the load stress evenly to a large base range, enhance the overall tensile strength of the soil, and effectively improve the stress distribution of the pavement structure. The strength of high tensile reinforced soil is far higher than that of unreinforced soil, greatly improving the bearing capacity of the soil.Qus,The grouting pipe can be divided into unconstrained grouting pipe and constrained grouting pipe according to whether it can absorb the pressure thrust (blind plate force) generated by the medium pressure in the pipe; According to the displacement type of the grouting pipe, it can be divided into axial grouting pipe, transverse grouting pipe, angular grouting pipe and pressure balance grouting pipe. The grouting pipe cannot bear load and should be hoisted separately; In addition to the pre deformation required by the design for pre stretching or cold tightening it is forbidden to adjust the installation deviation of the pipeline by deforming the grouting pipe; During installation, welding slag is not allowed to splash onto the surface of grouting pipe and suffer other mechanical damage; All movable components of the grouting pipe shall not be jammed by external components or restrict the normal operation of its movable parts. Most of the failure of the grouting pipe is caused by the external environment corrosion. Therefore, in the structural design of the grouting pipe, the contact between the external corrosion medium and the grouting pipe can be considered. For example, for the external pressure axial grouting pipe, a packing sealing device can be added between the outlet end ring and the outlet pipe, which is equivalent to the sleeve grouting pipe. It can not only resist the invasion of external corrosive media,KarinaAdvance small conduit for tunnel, the grouting pipe can also play a compensation role and avoid the failure of the grouting pipe. The use of grouting pipes has been indispensable in modern building construction. In the s, grouting pipes were popularized in China, but they were fastener grouting pipes. In the s, China began to develop advanced grouting pipes with multiple s. With the continuous development of China&#;s construction industry in modern times, and the bamboo wood grouting pipe has been eliminated by the market. Grouting pipe has become the mainstream form of grouting pipe and is more widely used in construction. Grouting pipe at tensioning end: the grouting pipe installed at the end of the grouting pipe reinforcement and capable of tensioning is also called grouting pipe grouting pipe. The so-called grouting pipe is a grouting pipe in post tensioning structure or component to maintain the tension of the grouting pipe reinforcement and transmit it to the mixed tension; Fixed end grouting pipe: a grouting pipe installed at the end of the grouting pipe reinforcement and usually buried in the concrete without tensioning. The standard of the grouting pipe used for the grouting pipe reinforcement is the national standard of the people&#;s Republic of China (GB / T -, which ensures that the products manufactured by our company conform to the product quality law of the people&#;s Republic of China and the standard law of the people&#;s Republic of China Grouting pipe is the only acoustic pipe specially used for ultrasonic testing in the market. The grouting pipe is made of cold and hard steel pipe after professional molding, and is connected by clamp pressure connection, screw connection, flange connection and other methods. It has a reliable anti-seepage effect during concrete pouring. Two convex grooves are planned at the end of the bell end of the high-strength double seal clamp type acoustic measuring pipe, and the convex grooves are equipped with sealing rings. When installing the device, the socket end of the product is stabbed into the bell end by cm, and then the two convex grooves are kneaded together with special hydraulic pliers. The pipe at the kneaded part is shortened and deformed after being stressed and the outer pipe between the two convex grooves is deeply immersed into the inner pipe, and then the reliable connection of the product is completed; After being kneaded, the rubber sealing ring deforms and fits between the two layers of pipes, playing an excellent double safety sealing effect.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,KarinaAdvance small conduit in tunnel construction, plastic grouting pipe, warp knitted grouting pipe, low elongation (≤ %), 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, dam engineering, water conservancy engineering and tunnel engineering; It has remarkable safeguard effect and good social and economic benefits against rutting and pavement cracking.

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, it is OK to check the sealing The second point is that the joint is misaligned or deformed during installation. 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, 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, 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.This seems to test what I learned in junior high school. The formula for calculating the weight per linear meter of a cylinder I learned at that time is now used. However, it may be more troublesome to calculate according to that formula. It is necessary to calculate the weight per linear meter of the outer cylinder with the formula, and then subtract the weight per linear meter of the inner space. I have a headache when I think about it! With less gossip, I&#;d better provide you with a method to correctly calculate the weight of the grouting pipe per linear meter! The cooperation Specification between the saddle profile on the horseshoe of the grouting pipe and the core is too low. When the outer mold and the horseshoe surface are fitted together, the gap is larger than the thickness of the pipe wall, there is an active gap. Therefore, the Chengdu grouting pipe manufacturer kneads the pipe wall to form an 'eight' shaped wrinkle.index,The grouting pipe without shaft roll packaging is tapped and paid off from the inner ring in the vertical state, and the drawn out pipe is spring shaped and automatically straightened. Takeout direction: the spiral direction of the spring shape after takeout is consistent with the twisting direction of, because the strength of the welding point is much lower than that of the steel itself, and it is easy to cause broken wires at the welding point during tensioning. When the grouting pipe adopts circular reinforcement arrangement, its bending radius shall not be less than times of the diameter. The wellhead clamp head is connected to the lower clamp head of the drive head. Some driving of grouting pipe.The glass fiber grouting pipe has the characteristics of easy construction, high temperature resistance, corrosion resistance, low elongation, high elastic modulus, no long-term creep, meeting the requirements of environmental protection, and has high tensile strength in the transverse and longitudinal directions. The strength to weight ratio of glass fiber is larger than that of steel, and the tensile strength can reach kn / m, which provides sufficient strength to prevent reflection cracks. When it breaks its elongation is less than %, it has high deformation resistance and good compatibility with asphalt mixture.

Glass fiber grouting pipe is a semi-rigid product made of glass fiber as raw material,KarinaSelf drilling hollow anchor manufacturer, high-strength alkali free glass fiber through a certain warp knitting process and fiber filament coated on both sides.reform,The use of grouting pipes has become indispensable in modern building construction, ranging from super high-rise and high-rise buildings to multi-storey buildings and indoor decoration construction. China has a longer history of using grouting pipes. Many of China&#;s ancient buildings have been listed as world-class material and cultural heritage, because China&#;s ancient buildings are very technical in construction. In China, before and in the early s, grouting pipes made of bamboo and wood were used in the construction of buildings. After the mounting bracket is welded on the surface of the grouting pipe, push the strain gauge in a stable and free state without bending and twisting; The mounting bracket and strain gauge shall be installed parallel to the support axis; When tightening the screw, pay attention to reasonably controlling the frequency of the strain gauge; The installation position of the strain gauge shall be selected at the position suitable for protection as far as possible.Ca （OH） +NaO·nSiO +mHO →CaO·nSiO·mHO+NaOH The wellhead clamp head is connected to the lower clamp head of the drive head. Some driving of grouting pipe.Karina,The grouting pipe with the grouting pipe as the core flexible element can be compensated in the axial, the internal pressure grouting pipe can be displaced in three directions, but because it is limited by casing and other accessories, it can often only be displaced in the axial direction. Therefore, the user needs to indicate the displacement in several directions when selecting and ordering, so as to select correctly. The working principle of the grouting pipe is to use its own elastic deformation to compensate the axial, angular, lateral and combined displacement of the pipe due to thermal deformation, mechanical deformation and various mechanical vibrations. The compensation has the s of sealing, pressure resistance, temperature resistance, corrosion resistance, impact resistance vibration reduction and noise reduction, which can reduce the deformation of the pipe and improve the service life of the pipe. Low cost, fast time, no loss, free from climate and place constraints. It is a thermoplastic material, which can be processed and formed many times, providing convenience for hot melting and electrofusion connection of pipes.
