Sometimes the grouting pipe is overlaid on the two sides of the horseshoe surface. Adjust the cooperation specifications of the grouting pipe at the distribution nozzle. How to avoid grout leakage during installation of grouting pipe?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,Loviisa Hollow self-propelled anchor rod manufacturer, its bending radius shall not be less than times of the diameter. The quality of the steel upsetting head of the grouting pipe is not directly related to its own quality, but the excessive strength will be harmful to the quality of the upsetting head. Therefore, when you choose the upsetting head anchor, you should explain it in detail to the manufacturer in the order.Loviisa , Professional sales, absolute sound detection tube price advantage providing the most cost-effective products.The research shows that the friction between the grouting pipe and the soil is also greatly related to the water content and compactness of the soil. The grouting pipe itself has a pattern, and is also a grid like integral geo reinforced material, so the friction between the grouting pipe and the medium is very large; The grouting pipe also has a great tensile strength, a large deformation modulus, and the reinforcement is stable and uniform, which can see good results in a short time. It can be seen from the experiment that the mesh reinforcement performance of the grouting pipe is better than the strip reinforcement material, which increases the stability of the project; The grouting pipe is especially suitable for the construction of high-speed highways, because the action force of the back and forth traffic on the soil is very great, and the grouting pipe can share the stress, increase the deformation modulus of the soil, effectively enhance the strength of the soil, and achieve the effect of stabilizing the project and long-term use.Sliema, 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.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, 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.It is necessary to comprehensively consider the selection and configuration of grouting pipes, because there are many types of expansion joints, and correct selection is very important. Only in this way can the design of the piping system be safe, reasonable, reliable and economical.?

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.Full section slurry discharge ( slurry discharge holes) is uniform and smooth. The grouting pipe is specially used as a channel for the depth detection of pile foundation and for structural stress calculation. The grouting pipe is a small pipe, but this small pipe meets the standard sensitivity of sound reception. As long as there is a small sound, it can measure it and accurately reflect the data on the computer or sound receiver. During the concrete pouring of cast-in-place pile, a channel that allows the ultrasonic probe to be normally placed at the pile bottom is reserved, which is not considered in the structural stress calculation.Home page recommendation,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, 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.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.In the process of using the acoustic pipe, it is necessary to have a detailed understanding of its installation method,Loviisa Grouting pipe grouting, 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, 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, it is necessary to pay attention to the method of the device in the process of the device, 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.

Answer: it varies according to the model and elasticity of the grouting pipe, and its internal pressure can reach bar or more.Where is good,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 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. Post grouting: after the shaft, tunnel, basement and other structures are dug, the grouting method is used to control water damage and strengthen the stratum, which is called post grouting.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, splitting and compaction, 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 resistanceLoviisa ,Disposal method: the grouting pipe shall be shortened according to the specification.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.The grouting pipe with the grouting pipe as the core flexible element can be compensated in the axial, lateral and angular directions on the pipeline. From the perspective of its performance,Loviisa Leading small conduit manufacturer, 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, which can reduce the deformation of the pipe and improve the service life of the pipe.
