The glass fiber grouting pipe is a rigid product made of high-strength alkali free peeling fiber, which is made into a mesh base material through an internationally advanced fine knitting process and is surface coated. Unidirectional tensile plastic grouting pipe is a grouting pipe made of high-density polyethylene (HDPE) as raw material, plasticized and extruded plate, punched, heated and stretched, extruded and pressed, and then punched with regular hole network, and then stretched longitudinally. In this process, the polymer is in a directional linear state and forms an oblong reticular integral structure with uniform distribution and high node strength. The tensile strength and rigidity of the grouting pipe are fully improved through the reorientation of the originally scattered chain molecules into a linear state by stretching. The grouting pipe is padded with the front lip of the horseshoe, and the height of the saddle shaped curved surface is changed to make the pipe wall crawl and slide along the accurate saddle shaped curved surface.Tezinets,Features: the grouting pipe is divided into disposable grouting pipe (ccll-y grouting pipe, qdm-it grouting pipe, ccll-y full section grouting pipe) and repetitive grouting pipe (ccll-d grouting pipe, ccll-d full section grouting pipe).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,TezinetsPipe shed and small conduit,TezinetsAdvance small conduit and pipe shed, 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, 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.White,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, otherwise fried dough twist or disorder will occur. Welding is strictly prohibited during use, 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.Grouting pipe grouting mainly improves the bearing capacity of piles from these two aspects Grouting is carried out through the grouting pipe embedded in the pile body. The slurry integrates the soil and slurry around the pile body through penetration, so as to improve the physical and mechanical properties of the bearing layer of the pile body Especially for the ballast at the bottom of the pile, grouting can improve or eliminate the adverse effect of the ballast at the bottom of the pile on the end bearing capacity through the replacement, compaction and consolidation of the ballast by the slurry.II During the drilling process of the bored pile, there will be a certain gap between the pile retaining wall and the surrounding soil layer, which will lead to the decrease of the pile side friction and affect the bearing capacity of the pile When the grouting pipe is used at the pile end for grouting, the slurry will permeate fill and compact along the side of the pile under the pressure, so as to complete the replacement of the mud skin around the pile and the filling of the gap, such as greatly improving the pile side friction resistanceThe small editor of prestressed machines and tools will lead you to understand the main connection methods between the drive device and the wellhead: the connection between the flange of the drive head of the electric oil pump and the parallel flange is the most widely used one at present. There is a flange at the lower part of the drive head, and the size matches the flange of the Christmas tree wellhead.

The glass fiber grouting pipe is a rigid product made of high-strength alkali free peeling fiber, which is made into a mesh base material through an internationally advanced fine knitting process and is surface coated. Unidirectional tensile plastic grouting pipe is a grouting pipe made of high-density polyethylene (HDPE) as raw material, plasticized and extruded plate, punched, extruded and pressed, and then punched with regular hole network, and then stretched longitudinally. In this process, the polymer is in a directional linear state and forms an oblong reticular integral structure with uniform distribution and high node strength. The tensile strength and rigidity of the grouting pipe are fully improved through the reorientation of the originally scattered chain molecules into a linear state by stretching.The single liquid silicification method is applicable to reinforce collapsible loess with permeability coefficient of . ~ m/d and silty fine sand with permeability coefficient of . ~ m/d. Glass fiber grouting pipe is a semi-rigid product made of glass fiber as raw material,TezinetsHollow self-propelled anchor rod manufacturer, high-strength alkali free glass fiber through a certain warp knitting process, and fiber filament coated on both sides.Executive standard,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, when the grouting pipe is found blocked after the foundation pile is poured and before the inspection, effective measures should be taken to pass the pipe to ensure the smooth progress of ultrasonic inspection. Generally, flushing and pigging with high-pressure water, and using a drill with a small drill to clean the hole.Two convex grooves are planned at the end of the bell end of the double seal clamp grouting pipe, and the convex grooves are equipped with sealing rings. During installation, and the pipe at the kneaded part is shortened and deformed after being stressed. The outer pipe between the two convex grooves is deeply embedded into the inner pipe and then the connection of the product is completed; After being kneaded, a rubber sealing ring is deformed and pasted between two layers of pipes, which plays a double safety sealing effect. 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, that is, there is an active gap. Therefore, the Chengdu grouting pipe manufacturer kneads the pipe wall to form an 'eight' shaped wrinkle.

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,Answer: Yes it can be protected. The piston rod can be protected by adding plastic hoses or bellows within the travel range.[patent attachment] [description] [] is the structural diagram of the utility model; [] is a schematic diagram of the cutting blade; [] is the schematic diagram of tightening the blade nut; [] is a schematic diagram of the fixed cutting device.When the grouting pipe is laid, it shall be kept flat and tight without wrinkling, so that the grouting pipe has effective tension. After laying, it shall be rolled again with a clean steel wheel roller. Most urban roads use glass fiber grouting pipes with self-adhesive. The diameter of the glass fiber grouting pipe is . ~ times of the maximum particle size of the asphalt concrete surface aggregate. The ultimate tensile strength should be greater than kN / m, so as to give play to the anti reflection crack performance of the glass fiber grouting pipe. It can also ensure the shear resistance and adhesive force of the adhesive layer of the glass fiber grouting pipe.Tezinets,They shall be connected as a whole in the factory as far as possible. If it is necessary to connect on site due to manufacturing process, transportation conditions, etc., hot press vulcanization (grouting pipe) or welding (plastic grouting pipe) shall be used. The joint appearance shall be smooth and smooth, and the tensile strength shall not be less than % of the base metal. The so-called 'overlapping' without any treatment is absolutely not allowed. All kinds of cross connection points of grouting pipes shall be made of accessories produced by our new rubber products factory, so as to ensure that on-site connection is only carried out in straight sections during construction. Flexible material with sufficient deformation capacity and good adhesion with concrete.Two convex grooves are planned at the end of the bell end of the double seal clamp grouting pipe, and the convex grooves are equipped with sealing rings. During installation, the spigot end of the product is stabbed into the bell end. The grouting pipe then kneads the two convex grooves together with a special hydraulic clamp, and the pipe at the kneaded part is shortened and deformed after being stressed. The outer pipe between the two convex grooves is deeply embedded into the inner pipe, and then the connection of the product is completed; After being kneaded, a rubber sealing ring is deformed and pasted between two layers of pipes, which plays a double safety sealing effect. 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.
