It is laid in the soil, and through the bite and interlock between the grouting pipe mesh and the soil, it forms an efficient stress transmission mechanism, so that the local load can quickly and effectively spread to the large area of soil, so as to reduce the local failure stress and improve the service life of the project. The convex joint steel plastic grouting pipe is an upgraded product of the ordinary steel plastic grouting pipe, which changes the shortcomings of the ordinary grouting pipe, such as the small peeling force of the joint (n), the easy cracking of the welding point, the difficulty of construction, and the reduction of the role of side displacement prevention. Due to the change of material ratio and construction technology the peeling force of the welding joint is between N and N, which effectively changes the above shortcomings of the traditional steel plastic grouting pipe. Because of the protruding joints at the welding position, it is called convex joint steel plastic grouting pipe, and its academic name is node reinforced steel plastic grouting pipe. The steel plastic grouting pipe is made of high-strength steel wire (or other fibers) through special treatment, polyethylene (PE) and other additives and is extruded to form a composite high-strength tensile strip. If the surface is rough embossed, and the drawn out pipe forms a spring shape and stretches automatically. Takeout direction: the spiral direction of the spring shape after takeout is consistent with the twisting direction of and is formed by welding its junction with the fusion welding technology of special reinforcement bonding. The grouting pipe is set out from the inner ring tap in the vertical setting out state it is a high-strength reinforced geotextile. This single belt is woven or sandwiched at a certain distance longitudinally and horizontally, otherwise fried dough twist or disorder will occur. The bottom of the horseshoe of the grouting pipe is too low. After the horseshoe is seated in the mold, the space between the outer mold and the horseshoe surface is greater than the thickness of the pipe wall.Copavour,Inner diameter: mm; Outer diameter: mm; Inner diameter tolerance: ± .mm; Length of each roll: m.It is laid in the soil, and through the bite and interlock between the grouting pipe mesh and the soil, it forms an efficient stress transmission mechanism, so that the local load can quickly and effectively spread to the large area of soil, so as to reduce the local failure stress and improve the service life of the project.

In order to enable everyone to provide production to the factory normally, 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,CopavourSupport small conduit, 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, 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. The bottom of the horseshoe of the grouting pipe is too low. After the horseshoe is seated in the mold, the space between the outer mold and the horseshoe surface is greater than the thickness of the pipe wall.The Xiaobian of prestressed machines and tools reminds us that there are many forms of grouting pipes, including the following. According to the type of reinforcement of the grouting pipe, it can be divided into the grouting pipe of thick reinforcement of the grouting pipe, the grouting pipe of parallel reinforcement (wire) bundle of the grouting pipe, and the grouting pipe of steel strand bundle of the grouting pipe. For thick reinforcement, one grouting pipe is generally used to anchor one reinforcement. For tendons and steel strands, a grouting pipe must anchor several steel bars or steel strands at the same time, which are often arranged in a ring or circle, or in a rectangle. Obviously,CopavourGrouting anchor, due to the different number and arrangement of prestressed reinforcement, the form and structure of grouting pipe will also be different. According to the principle of grouting pipe and transmitting pretension, grouting pipe relying on friction and grouting pipe relying on adhesion.

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.Introduction to the advantages of grouting pipe: Simple installation, complete supply; The grouting pipe can be cut at the construction site according to the actual required length of the joint (it is recommended that the longer grouting outlet length should not exceed m); No special installation equipment is required; Grouting time can be arbitrarily selected; When grouting is carried out internally under proper pressure, the grouting pipe fluid can keep filling the whole pipe evenly; The system allows grouting under relatively low pressure; The grouting pressure is .-.mpa; The installation will not affect the characteristics of the building grouting pipe; The installation or grouting process will not harm the concrete; Permanent sealing can be ensured after grouting; If there is no leakage, it has higher tensile resistance and better sealing performance.technological innovation,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, 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, 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.The commonly used standard for grouting pipe is the inner diameter of -mm. The wall thickness of the pipe has little effect on the sound transmission, so there is generally no need to restrict the thickness of the pipe wall. However, from the perspective of saving steel consumption, it is OK if the pipe wall can bear the lateral pressure of new concrete, not necessarily the thicker the better.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.

The glass fiber grouting pipe has the characteristics of easy construction, 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.Quality risk, The saddle shaped curved surface on the horseshoe surface of the grouting pipe and the upper and outer molds are not well fitted, which is caused by the Chengdu grouting pipe manufacturer&#;s failure to smooth (flatten) the grouting pipe along the horseshoe surface.[] 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. 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, but also add a safety barrier to the grouting pipe. Even if the grouting pipe is damaged, 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, the construction industry has become increasingly mature and perfect in China, 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.Copavour,In China, the types of grouting pipes are relatively complete now, from grouting pipes and grouting pipes for Reinforcing Subgrade to glass fiber grouting pipes for highway pavement to convex joint grouting pipes and plastic tensile grouting pipes for railway. For different road construction environments, different types of grouting pipes are selected, which can not only ensure the quality of the road but also save the cost. So what kind of application effect can the grouting pipe achieve in highway maintenance? The grouting pipe manufacturer will take you to have a look.When the pipe cannot be connected due to serious blockage, the following treatment principles must be followed: when it is the first pile of a certain bridge, 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. Common problems and answers of grouting pipe what is the pressure inside the grouting pipe? The wellhead clamp head is connected to the lower clamp head of the drive head. Some driving of grouting pipe.
