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 ChinaHowever, 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, plastic grouting pipe etc.) and flexible reinforcement (polypropylene strip, 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, 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.Regina,Features of reusable grouting pipe: with one-way switch . Good anti blocking property and no backflow of slurry.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,Regina42 small catheter, the deformation compensation of the pipe system can be determined according to these relatively simple pipe sections, so as to select the grouting pipe.Rotterdam,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, shaping, coiling and other processes. Compared with metal textile mesh and plastic woven mesh, 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.The glass fiber grouting pipe is a rigid product made of high-strength alkali free peeling fiber, which is made into a mesh base material through an internationally advanced fine knitting process and is surface coated. Unidirectional tensile plastic grouting pipe is a grouting pipe made of high-density polyethylene (HDPE) as raw material, plasticized and extruded plate, punched, heated and stretched, and then punched with regular hole network, and then stretched longitudinally. In this process, the polymer is in a directional linear state and forms an oblong reticular integral structure with uniform distribution and high node strength. The tensile strength and rigidity of the grouting pipe are fully improved through the reorientation of the originally scattered chain molecules into a linear state by stretching. 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, that is, there is an active gap. Therefore,ReginaSupport advance small conduit, the Chengdu grouting pipe manufacturer kneads the pipe wall to form an 'eight' shaped wrinkle.

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 detection pipes can be welded or bundled inside the reinforcement, and the detection pipes should be parallel to each other.In the construction of some grouting pipes, after the completion of the construction of the project, the project was damaged due to some external factors. In order to help users effectively improve the construction quality of the grouting pipes, the following article introduces the protective measures that should be taken after the completion of the construction of the waterproof layer of the grouting pipes. For various engineering designs, waterproof and water stop shall be carried out throughout the whole process of grouting pipe until the backfilling soil is completed.technical service,How to deal with the joint if the grouting pipe is installed in sections? If the grouting pipe is installed in sections, the joints must be welded. The welded joints of the section steel have been prepared in the manufacturing plant, and can be installed after the two-phase adjacent joints are aligned. After all beams are welded, anchor them according to the above steps. Install the formwork at the beam end. The formwork shall be made according to the overall dimensions of Hainan grouting pipe device and the notch of the reserved slot. The formwork shall be made quite tight to prevent mortar from flowing into the displacement control box or into the beam end gap.After checking that the installed formwork is tight and seamless, clean the reserved groove, then pour concrete and vibrate it tightly. The concrete shall have at least the same strength as the structural concrete at this place, and the grouting pipe device in Hainan shall be kept clean when pouring concrete.Disposal method: the grouting pipe shall be shortened according to the specification. 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, etc.

At the same time, because the space in the grouting pipe restricts the lateral sliding and rolling of the soil particles inside, the relative displacement trend or relative displacement also occurs between this part of soil particles and adjacent soil particles, resulting in friction. This friction force is generally called 'bite force' or 'lateral force resistance'. The 'surface friction' and 'bite force' make the slip and roll of soil particles under the force of the upper limit line at the location of the grouting pipe, and limit the lateral displacement of soil in the whole plane of the grouting pipe. The grouting pipe plays an important role in the key points of settlement. Therefore, it is reasonable to use the grouting pipe to treat the uneven settlement of fill excavation transition subgrade. This paper yzes the action mechanism of the grouting pipe according to its type and characteristics, introduces the construction technology and process in the construction of preventing the reflection crack of the road surface, and proposes a new technology of sprinkling a layer of filler in the grouting pipe network when paving the surface course. As a kind of road reinforcement material, grouting pipe is widely used in road maintenance engineering because of its advantages of simple,Reginamanufacturer of composite anchor rod, fast construction and low investment.Quality improvementThe 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. Cut and cut the spring skeleton grouting pipe according to the components. The cutting surface must be flat and free of burrs. The length of its flat section must be ≥ the connecting reinforcement measures. During the bending process of the grouting pipe, it is not allowed to use a small one. The inner diameter of the grouting pipe is compressed and cracked. The alignment between M and FL is - It is applicable to the laying of buried pipes in gas pipeline projects, and is not applicable to the use of open pipes. The service life of pipes will be affected by the perennial ultraviolet corrosion of sunlight. How to use the grouting pipe after rusting will not affect its . The grouting pipe is a kind of rubber plate we often see. It is widely used and has a long service life. It has been praised and recognized by people. Next, I will introduce the relevant knowledge of the grouting pipe we produce in detail!Regina,Disposal method: the grouting pipe shall be shortened according to the specification.The important reason for the stability of the grouting pipe reinforced soil subgrade is to further verify the main principle of the grouting pipe reinforced soil subgrade treatment technology. It is to place various types of grouting pipe products inside, on the surface of the soil mass or between the layers of soil mass. Relying on the tensile characteristics of the grouting pipe, 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.
