Disposal method: the grouting pipe shall be shortened according to the specification.Two convex grooves are planned at the end of the bell end of the double seal clamp grouting pipe and the convex grooves are equipped with sealing rings. During installation, the spigot end of the product is stabbed into the bell end. The grouting pipe then kneads the two convex grooves together with a special hydraulic clamp, and the pipe at the kneaded part is shortened and deformed after being stressed. The outer pipe between the two convex grooves is deeply embedded into the inner pipe, and then the connection of the product is completed; After being kneaded, a rubber sealing ring is deformed and pasted between two layers of pipes, which plays a double safety sealing effect.Costa Rica, The grouting pipe is a thermoplastic material which can be processed and formed many times, which provides convenience for the hot-melt and electric fusion connection of the pipe.The stability of the grouting pipe is one of the important factors to control the stability of the whole foundation pit. Its erection must be accurate and in place, and prestress must be applied in strict accordance with the design requirements. In particular, attention should be paid to the stability of the diagonal bracing. During the diagonal bracing operation, every link of the installation must be carefully operated. At the same time, the steel purlin must also ensure its stability strength and deformation requirements during the production and installation process. In addition, the grouting pipe must be strictly monitored to ensure its stability. How to improve the bearing capacity of piles with grouting pipes in bored piles, during the drilling process of large-diameter cast-in-place piles, the soil layer around the piles will become loose due to the agitation of the turning heads. In addition, the water immersion makes the soil layer that has started to loosen more loose. This problem can be effectively solved by grouting with grouting pipes. How to improve the bearing capacity of piles when grouting with grouting pipes?Song Cau,?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.The following aspects shall be paid attention to during the construction of grouting pipe: when the construction personnel are binding reinforcement and erecting formwork, reliable fixation measures must be taken for the buried grouting pipe to avoid displacement during concrete pouring and ensure the correct position of the grouting pipe in the concrete. When fixing the grouting pipe, only the allowable part of the grouting pipe can be perforated and the body part shall not be damaged. The grouting pipe shall be fixed according to the construction specifications required by the design. The common fixing methods are: using additional reinforcement; Fixed with special fixtures; Fix with lead wire and formwork. No matter what fixing method is adopted, the grouting pipe must be positioned accurately, without damaging the effective part of the grouting pipe, there are many sharp stones and sharp edged reinforcement in the concrete, so when pouring, vibrating and positioning the grouting pipe, attention should be paid to the impact force of pouring and vibrating, so as to avoid piercing the grouting pipe due to excessive force.?

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,Costa Ricamanufacturer of composite anchor rod, 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,Costa RicaAdvanced small conduit processing, 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. * * mm grouting pipe made of qb. kg per meter, kg per piece. Results the average weight of * * mm grouting pipes was kg, with a difference of kg per ton. It can be imagined how big the gap is when the one foot rate of retreat is large. The grouting pipe is used as the pipe for grouting at the bottom of the pile. The test shows that the bearing capacity of the cast-in-place pile treated with the pile bottom grouting can be greatly improved At the same time, the grouting pipe can also be used as the pipe for the defect washing and grouting treatment of the accident pile. At this time, it is necessary to take measures to punch the pipe at the defect position where grouting is required. The classification of the grouting pipe can be divided into three categories according to the pipe materials: the advantages of steel pipe steel pipe are that it is easy to install, and it can be welded on the reinforcement frame by electric welding, which can replace part of the reinforcement section, and because of the large rigidity of the steel pipe After embedding, the parallelism and straightness can be basically maintained. At present, many large-diameter cast-in-place piles use steel as the grouting pipe. However, the price of steel pipe is relatively expensive: steel corrugated pipe steel corrugated pipe is a better grouting pipe material. It has the characteristics of thin pipe wall, less steel, impermeability, pressure resistance, high strength and good flexibility. It is usually used for post tensioning reserved holes in prestressed structures: when used as grouting pipe. It can be directly bound to the reinforcement framework soil, and the joint can be connected with a larger corrugated sleeve. Since the bellows is light, it is very convenient to operate, but attention should be paid to keeping its axis straight during installation.quality,It is required to ensure that at least one embedded reinforcement is firmly welded with the anchor ring of maolehan grouting pipe within every meter along the joint direction. The quality of XF type grouting pipe should be carefully checked. If deformation or inconsistent spacing between two steel beams is found, 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 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. The length can be matched according to the construction requirements,Costa RicaAdvance grouting small conduit, without loss.The foundation pit excavation shall strictly follow the principle of 'layered excavation'. The support erection shall be closely coordinated with the earthwork excavation. During the excavation, the earthwork near the grouting pipe shall be excavated by the central trenching method to prevent the machinery from colliding with the support; The earthwork near the slope protection pile shall be excavated manually with small machines and tools. It is forbidden to collide with the grouting pipe and bored pile by mechanical excavation. After the earthwork is excavated to the design elevation, the grouting pipe shall be erected and prestressed in time to reduce the exposure time without support.

The fixed cutting device is mainly composed of a cutting blade and a pulley. The expansion and contraction diameter of the blade is adjusted by the bolts at the tail of the rotating flange to cut the grouting pipe. The rotating blade and the pulley are connected to the rotating device through slots.[] the outer diameter of the cutting rotary device is mm smaller than the inner diameter of the grouting pipe, so that the device can smoothly extend into the grouting pipe for cutting.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, 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.Costa Rica,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, reinforced concrete strip, 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, 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.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 existence of grouting pipe mesh restricts the lateral movement of soil.
