It is proved by experiments that the bearing capacity of the same bored pile with and without grouting pipe is separated by %. That is why more and more bored piles and grouting pipe grouting are used more and more widely in China The grouting pipe is a patented product. Compared with similar products in the market, it has higher tensile resistance and better sealing performance.leon,Grouting time can be arbitrarily selected; When grouting is carried out internally under the action of appropriate 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 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.Castro,Before the installation of the grouting pipe, it is necessary to check whether the processed support is vertical to the grouting pipe fitting, and correct the non vertical support; Then install the grouting pipe on the bracket and fasten it.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, when the grouting pipe is found blocked after the foundation pile is poured and before the inspection and even can not be detected. Therefore, 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 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, extrusion, molding, punching, stretching, shaping, it has light weight, high strength, isotropy, and antistatic, It is a new type of mesh grouting pipe material for underground coal mine support engineering and civil engineering.
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, easily bypass obstacles, and is convenient for construction.The installation will not affect the characteristics of the building grouting pipe itself; The installation or grouting process will not harm the concrete; Permanent sealing can be ensured after grouting; If there is no leakage, grouting is not allowed; Ccll-y series grouting pipe: grouting once, not reusable ccll-d series grouting pipe: multiple times of grouting, grouting is not limited by time.It is applicable to waterproof joints of subway, tunnel and basement. If there is water leakage, grout can be injected into the pipe body to fill and seal. It is very suitable to install grouting pipes between the joints of new and old concrete. Various materials such as cement slurry, the joint can be sealed by injecting slurry into the PVC port or spring skeleton 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. Action mechanism of grouting pipe: the grouting pipe is a flexible material. Under the action of soil load, it is a mechanism of dispersing the force on each hole belt and forming a resultant force.reform, The wellhead clamp head is connected to the lower clamp head of the drive head. Some driving of grouting pipe. 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, 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, and strong interlocking and occlusive effect on the soil, it can effectively treat the soft soil foundation, restrict the lateral displacement of the soil, overcome the uneven settlement of the soil, 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.
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, 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 Chinas construction industry in modern times,leonAdvance small conduit and pipe shed, 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.How much does it cost?,Answer: according to the length and diameter the weight of common grouting pipe is . ~ .KG, and the weight can reach several kilograms.Application scope and development space of grouting pipe as a new term, grouting pipe has gradually appeared in some online newspapers and periodicals, and its practical scope has also developed from the support of some basic automobile boot and engine cover to the machinery manufacturing industry, used for the support of equipment accessories, vibration reduction of equipment, support of tool box cover, medical industry, fitness equipment and other fields. As its practicality is further recognized, its scope of application is becoming wider and wider. Some people in the industry asked: the application range of grouting pipe is becoming wider and wider. Does it have an impact on the original telescopic spring? In my personal opinion, it will not impact the original spring. Of course it will have a certain impact, the rear box of a tricycle was originally supported by an iron bar (which is still useful). Now because most of the grouting pipes are innovations in the product design of some enterprises. For example, the grouting pipe is very light, convenient and labor-saving. Some units do not know it, so its design has certain limitations, However, enterprises must be innovative in order to be ahead of their peers. We have been making grouting pipes for many years. Experience tells us that many manufacturers are now trying our grouting pipes, and they have been officially used, with obvious effects. However, some enterprises do not know what the grouting pipes are, let alone their s, so they will be in a passive position. Therefore, we hope that some industries, such as machinery manufacturing, automobile and motorcycle, transportation equipment, box manufacturing such as tool boxes, medical treatment, fitness, kitchen cabinets, etc If you need to know the and use of the grouting pipe, please feel free to consult me, and I will give you advice(the density of steel pipe is kg/dm calculation formula: w = . (D-S) s where: W - theoretical weight of steel pipe per meter, kg / M; D - Nominal outer diameter of steel pipe, mm; S - nominal wall thickness of steel pipe, mm.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, 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.

Grouting pipe has become the mainstream form of grouting pipe and is more widely used in construction.leon, After the two pipes are connected by using the deformation of the grouting pipe the kneading part of the joint is large at both ends and small in the center, so that the joint is stuck at one time, avoiding the possibility of loose union. The grouting pipe has proper, stable and excellent s in terms of tensile pull-out and torque resistance, and the protrusion is circular arc with small protrusion, which is useful to avoid collision with conduits, vibrators,leonPipe shed and small conduit, etc. After the two pipes are connected by using the deformation of the grouting pipe, the kneading part of the joint is large at both ends and small in the center, so that the joint is stuck at one time, avoiding the possibility of loose union. The grouting pipe has proper, and the protrusion is circular arc with small protrusion, which is useful to avoid collision with conduits, vibrators, etc. Grouting pipe at tensioning end: the grouting pipe installed at the end of the grouting pipe reinforcement and capable of tensioning is also called grouting pipe grouting pipe. The so-called grouting pipe is a grouting pipe in post tensioning structure or component to maintain the tension of the grouting pipe reinforcement and transmit it to the mixed tension; Fixed end grouting pipe: a grouting pipe installed at the end of the grouting pipe reinforcement and usually buried in the concrete without tensioning. The standard of the grouting pipe used for the grouting pipe reinforcement is the national standard of the peoples Republic of China (GB / T -, which ensures that the products manufactured by our company conform to the product quality law of the peoples Republic of China and the standard law of the peoples Republic of China Grouting pipe is the only acoustic pipe specially used for ultrasonic testing in the market. The grouting pipe is made of cold and hard steel pipe after professional molding,leon32lead small conduit, and is connected by clamp pressure connection, screw connection, and the convex grooves are equipped with sealing rings. When installing the device, the socket end of the product is stabbed into the bell end by cm, and then the two convex grooves are kneaded together with special hydraulic pliers. The pipe at the kneaded part is shortened and deformed after being stressed, and the outer pipe between the two convex grooves is deeply immersed into the inner pipe, and then the reliable connection of the product is completed; After being kneaded, the rubber sealing ring deforms and fits between the two layers of pipes, playing an excellent double safety sealing effect.
