The longitudinal overlapping width of grouting pipe and grouting pipe shall not be less than cm, and the transverse overlapping width shall not be less than cm. The former shall be placed on the latter according to the asphalt paving direction. After laying the glass fiber grouting pipe, fix the glass fiber grouting pipe with high-quality cement nails and fixed iron sheets with a size of mm, mm and a thickness of .mm. The fixed spacing can be determined according to the actual construction situation.Can the piston rod of the grouting pipe be protected to avoid being bruised and accelerating leakage?Bai Linggen The grouting water ratio of grouting construction is .: ~ .: (i.e. the weight ratio of water and cement), and the principle of 'dilute first and then dense' is adopted. Por early strength Portland cement is used as the cement. Before mixing the cement slurry, the quality of the cement shall be checked. If it is found that the cement is hardened and deteriorated or fails the test, it shall be discarded to prevent the quality of pile end grouting from being affected by the deteriorated cement. The grouting time should be - days and - days after the completion of single bearing platform pile construction.The longitudinal overlapping width of grouting pipe and grouting pipe shall not be less than cm, and the transverse overlapping width shall not be less than cm. The former shall be placed on the latter according to the asphalt paving direction. After laying the glass fiber grouting pipe, fix the glass fiber grouting pipe with high-quality cement nails and fixed iron sheets with a size of mm, mm and a thickness of .mm. The fixed spacing can be determined according to the actual construction situation.Gandia,Answer: Yes, but for a grouting pipe that has been designed, its elastic extension speed is certain.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,Bai Linggen32lead small conduit, 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.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.

Causes of wrinkling: the blanking specification of pipe joint is too long.The disposable grouting pipe uses steel springs as the supporting framework, and is wrapped with a layer of non-woven filter cloth. The outermost layer is wrapped with nylon mesh, and can only be grouted once.Answer: Yes, but for a grouting pipe that has been designed, its elastic extension speed is certain.Pursuit of excellence, It has good flexibility. The pipes can be coiled when they are produced, so that the number of joints in the pipe network can be reduced. It can be laid according to the terrain, and is convenient for construction.In recent years, there have been frequent natural disasters, such as mountain slides, floods, earthquakes, fires, the subgrade will not be greatly damaged due to natural disasters, so that we can save more people in the rescue work. The grouting pipe can also play a great role in slope protection. The use of the grouting pipe can well prevent the landslide of mountain soil and debris flow disasters. Through many years of practical experience, it has been proved that the roads that usually use the grouting pipe are far more than the same period of projects in terms of service life and quality. Thus reducing the casualty rate. Grouting pipe is a kind of excellent geosynthetics used for Pavement Reinforcement, old road reinforcement, subgrade reinforcement and soft soil foundation reinforcement. It has become an irreplaceable material in the application of asphalt pavement reflection crack treatment. This product is a semi-rigid product made of high-strength alkali free grouting pipe, which is made of mesh base material through internationally advanced warp knitting process and surface coating treatment. It has high tensile strength and low elongation in both longitude and latitude, and has excellent properties such as high temperature resistance, low cold resistance, aging resistance and corrosion resistance. It is widely used in asphalt pavement, cement pavement and subgrade reinforcement, railway subgrade, embankment slope protection, airport runway, sand prevention and control projects. Grouting pipe laying and fixing of grouting pipe laying of glass fiber grouting pipe can be carried out by special equipment refitted from tractors or automobiles, or manually.The 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.

In recent years, there have been frequent natural disasters, such as mountain slides, floods,Bai LinggenGrouting flower tube, earthquakes, fires, etc. we are so small in the face of natural disasters that we can only devote our efforts to normal prevention and post disaster rescue. The grouting pipe can reduce the damage caused by these natural disasters.Grouting pipe is an expert in road construction. It can connect the subgrade as a whole and improve the bearing capacity of the subgrade. When encountering natural disasters, the subgrade will not be greatly damaged due to natural disasters, so that we can save more people in the rescue work. The grouting pipe can also play a great role in slope protection. The use of the grouting pipe can well prevent the landslide of mountain soil and debris flow disasters.

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. Installation of grouting pipe the method of installing grouting pipe is to bundle the grouting pipe and add -mm semi-circular flower pipe at the upper end of the reinforcement construction; As the project is a bored pile, the commonly installed grouting pipe is a straight pipe. A diffuser with one-way is set at min below the pipe. The grouting pipe is installed at the end of the reinforcement cage installation and sediment treatment (because the end of the bored pile is cone-shaped, in order to avoid damaging the one-way diffuser at the end of the grouting pipe when lowering the reinforcement cage, it is not appropriate to bundle the grouting pipe on the reinforcement cage and lower it at the same time.) The grouting pipe is set in the diffuser with one-way and must be wrapped with a special inner tube. After the pipe is lowered, the grouting pipe must be filled with water, and the upper end of the grouting pipe should be blocked.?Bai Linggen, performance of grouting pipe the grouting pipe is light in weight, has strong bite force with soil or gravel, is acid-base resistant, 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. The grouting pipe is used to pad the bottom of the horseshoe, change the cooperation specification of the mold, and adjust the cooperation space between the lower tire and the horseshoe.Causes of wrinkling: the blanking specification of pipe joint is too long.
