The grouting pipe diffuses the load on it. When the reinforced soil is loaded, the grouting pipe has a high bond with the soil, and has a mutual embedding effect 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,requirementGrouting small conduit, 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.Grouting pipe grouting pipe manufacturer clamp type grouting pipe grouting pipe price grouting pipe spot grouting pipe specification grouting pipe model grouting pipe raw material for grouting pipe grouting pipe is processed by welded pipe or spiral steel pipe, and grouting pipe processed by seamless steel pipe is generally rare in the market. The reasons are as follows: first, in terms of price, generally, 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, 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, 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.requirement,[] the fixed cutting device is mainly composed of a cutting blade and a pulley The cutting blade and the pulley are respectively connected to both sides of the cutting rotary device through slots. The cutting blade is shown in Fig. 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, 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 (≤ %), and strong interlocking and occlusive effect on the soil, it can effectively treat the soft soil foundation, 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.Xochimilco,Can the stretching speed of grouting pipe be defined?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. It is a thermoplastic material, 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.[] further, the cutting rotating device rotates the cutting blade and pulley through a socket wrench to cut the casing wall.When the grouting pipe is installed, the axis deviation shall be ≤ cm, and the bearing capacity of the support joint shall meet the design requirements. When connecting the grouting pipes, bolts must be installed symmetrically and tightened in sequence. Meanwhile, the deflection must be corrected to the horizontal before axial force is applied.Where to sell API,The mesh structure of the grouting pipe can make the pore water pressure dissipate faster, and effectively accelerate the drainage and consolidation of the soft soil of the foundation. This is very important for strengthening soft clay foundation. Precautions for grouting pipe installation: when tensioning the prestressed reinforcement, it shall be loaded from zero to the initial tension at the starting point of the measured elongation value, and then loaded to the required tensioning force by stages; Stress control and elongation check shall be adopted for tensioning management of prestressed reinforcement. The allowable deviation between the actual elongation value and the calculated elongation value is - % ~ + %. If the value is exceeded, the tensioning shall be suspended; Tensioning can be continued only after taking measures to adjust; If the elongation value is too small, over tensioning measures can be taken, but the tensioning force limit shall not be greater than .fptk; In the multi wave curve prestressed reinforcement in order to increase the tensile stress at the inner support and reduce the tensile stress at the lower mouth of the grouting pipe after tensioning, the technology of over tensioning and loosening can be adopted; The duct grouting shall be dense and the strength grade of cement slurry shall not be lower than C. Before grouting, the duct shall be wet and clean,requirementSeamless small conduit, the grouting shall be carried out slowly and evenly without interruption, and the exhaust shall be smooth. If the hole is blocked, the grouting port must be replaced, but the cement slurry injected for the first time must be discharged to avoid gas between the two grouts. After the holes are filled and the exhaust holes are closed the pressure should be increased to .-.mpa, and the grouting holes should be closed later. The grouting pressure of the vertical duct shall be determined according to the grouting height; For the duct grouting of multi span continuous prestressed tendons connected by connectors, one span shall be grouted after tensioning, and it is not allowed to grout once after all the spans are tensioned; The exposed length of the prestressed reinforcement grouting pipe after fixation shall not be less than mm, and the grouting pipe shall be protected with end sealing concrete. When it needs to be exposed for a long time, measures to prevent corrosion shall be taken; When the steel strand has floating rust, please remove the floating rust and dirt of the steel strand at the fixed clamping section of the grouting pipe and its outer end, so that the floating rust and dirt will fill the red groove of the clamping piece during installation and tensioning and cause wire sliding; The tool clamping piece is three pieces and the working clamping piece is two pieces. The two cannot be mixed. The working grouting pipe cannot be used as a tool and the grouting pipe cannot be reused; The grouting pipe shall be kept properly and shall be free of rust, water and other sundries during use. The working clip can be used after removing the foam in the packaging box. However, when the prestressed tendon is long and the grouting pipe must be repeatedly tensioned and fixed, it is recommended to apply a small amount of lubricant (such as withdrawing the grouting pipe) in the conical hole of the grouting pipe plate, which is not only conducive to the follow-up of the working clip and withdrawing the grouting pipe, but also conducive to the multiple grouting pipe fixation of the grouting pipe; The outer surface of the tool clip and the inner surface of the conical hole of the grouting tube plate shall be coated with lubricant before use, and the debris on the clip surface shall be removed frequently to make the grouting tube flexible. However, when the clip is cracked or the tooth surface is damaged, it shall be replaced and shall not be used again; Safety measures shall be taken during tensioning, and no one shall stand after tensioning the jack; The grouting pipe solid system shall be used together and shall not be mixed with other systems. If the static load test is to be conducted, please clean the clamp with organic solvent (such as gasoline) and wipe the anti rust oil of the grouting tube plate hole, otherwise the solid performance of the grouting tube will be affected; The pile foundation grouting pipe is an important channel product for pile foundation depth detection. It has two main s, the following treatment principles must be followed: when it is the first pile of a certain bridge and the other is as a pipe for grouting at the bottom of the pile.When the pipe cannot be connected due to serious blockage, 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!When the grouting pipe is installed, the axis deviation shall be ≤ cm, and the bearing capacity of the support joint shall meet the design requirements. When connecting the grouting pipes, bolts must be installed symmetrically and tightened in sequence. Meanwhile, in order to prevent excessive deflection of the grouting pipes when axial force is applied, the deflection must be corrected to the horizontal before axial force is applied.

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. The grouting pipe shall be cut with a toothless saw (grinding wheel clamp). Cutting by electric or gas welding is easy to damage the surrounding surface and cause local heating at the end, which significantly reduces its performance. During the use of the grouting pipe, it is forbidden to take any form of heating deformation measures to avoid reducing the mechanical properties of the grouting pipe.Marketing Department,?The repetitive grouting pipe can be reused for many times, and the core and outer wall of the pipe need to be cleaned after each use. Advantages of grouting pipe grouting pipe is an embedded grouting pipe system, which is used for permanent sealing of construction joints, cold joints, pipe seepage joints and gaps between ground walls in concrete. It is very suitable to install grouting pipes between the joints of new and old concrete. When water penetrates into the joint, it can be sealed by injecting slurry into the PVC port set on the surface. The proper grouting time can be selected after the concrete curing. Leakage joints can also be permanently sealed in this way. The wellhead clamp head is connected to the lower clamp head of the drive head. Some driving of grouting pipe.requirement,The grouting pipe at the tensioning end has good anchoring energy and self anchoring energy. Grouting pipe is generally used for tensioning. The grouting pipe at the tensioning end is composed of four parts: clip anchor plate, anchor base plate and spiral reinforcement. The clip is the key part of the anchoring system. It is two-piece and made of high-quality alloy steel.Can the stretching speed of grouting pipe be defined?The bi-directional tensile plastic mesh false roof used in underground coal mine with mine grouting pipe is specially designed and manufactured for the false roof support of underground coal mining face and roadway wall support. It is made of several high molecular polymers and filled with other modifiers through heating, molding, punching, stretching, shaping, coiling and other processes.
