and the drawn out pipe is spring shaped and automatically straightened. Takeout direction: the spiral direction of the spring shape after takeout is consistent with the twisting direction of

The grouting pipe without shaft roll packaging is tapped and paid off from the inner ring in the vertical state, otherwise fried dough twist or disorder will occur. Welding is strictly prohibited during use, because the strength of the welding point is much lower than that of the steel itself, and it is easy to cause broken wires at the welding point during tensioning. When the grouting pipe adopts circular reinforcement arrangement, its bending radius shall not be less than times of the diameter.Answer: it varies according to the model and elasticity of the grouting pipe, and its internal pressure can reach bar or more.Ajax, The grouting pipe can be intercepted at the construction site according to the actual required length of the joint (it is recommended that the longest 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 the pressure, the grouting pipe liquid can keep uniformly filling the whole pipe; The system allows grouting under relatively low pressure; sevenThe 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, 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,AjaxAdvance small conduit tunnel, it can be divided into grouting pipe relying on bearing pressure, grouting pipe relying on friction and grouting pipe relying on adhesion.Naousa,The small editor of prestressed machines and tools will lead you to understand the main connection methods between the drive device and the wellhead: the connection between the flange of the drive head of the electric oil pump and the parallel flange is the most widely used one at present. There is a flange at the lower part of the drive head, and the size matches the flange of the Christmas tree wellhead. 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, the Chengdu grouting pipe manufacturer kneads the pipe wall to form an 'eight' shaped wrinkle.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.

It has good air tightness, low gas permeability, strong sealing and no leakage. Non woven filter cloth layer outside the framework. Only water and grout are allowed to pass through, and other materials such as cement slurry in concrete are blocked outside the grouting pipe to ensure smooth use of the whole section of the grouting pipe.A short section of screw end rod is welded on both ends of a single prestressed thick steel bar, and the nut and backing plate are sleeved to form the simplest grouting pipe. The pretension force is transmitted to the nut through the bearing force on the threaded slope of the screw end rod, and then to the concrete components around the reserved hole crossing through the base plate.Let&#;s take a look at the prestressed machines and tools. The small editor of prestressed machines and tools reminds everyone that the screw end rod is made of cold drawn or heat-treated reinforcement, and the thread is fine teeth. The welding between the end rod and the prestressed reinforcement should be carried out before the cold drawing of the prestressed reinforcement. This grouting pipe can be used at the tensioning end and the fixed end. A general jack is used for tensioning, and the jack pull rod (with internal thread at the end) is tightened on the thread of the screw end rod for tensioning. After tensioning, tighten the nut and anchor the rebar. The advantages of this grouting pipe are relatively simple, and when the jack returns oil after the grouting pipe, the prestressed reinforcement basically does not slide. If necessary, facilitate re tensioning. The disadvantage is that the accuracy of the length of prestressed reinforcement is high and it cannot be too long or too short, otherwise the thread length is not enough.Statistics,Grouting pipe grouting mainly improves the bearing capacity of piles from these two aspects Grouting is carried out through the grouting pipe embedded in the pile body. The slurry integrates the soil and slurry around the pile body through penetration, splitting and compaction, so as to improve the physical and mechanical properties of the bearing layer of the pile body Especially for the ballast at the bottom of the pile, grouting can improve or eliminate the adverse effect of the ballast at the bottom of the pile on the end bearing capacity through the replacement, compaction and consolidation of the ballast by the slurry.II During the drilling process of the bored pile, there will be a certain gap between the pile retaining wall and the surrounding soil layer, which will lead to the decrease of the pile side friction and affect the bearing capacity of the pile When the grouting pipe is used at the pile end for grouting, fill and compact along the side of the pile under the pressure, such as greatly improving the pile side friction resistanceIn the engineering practice, some construction units directly pave the glass fiber grouting pipe after spraying the sticky layer oil, and the roller rolls after it. The effect is good, and the glass fiber grouting pipe is not easy to wave. Strictly control the entry and exit of vehicles transporting the mixture, and forbid vehicles to swerve, brake and dump the leftover mixture on the grouting pipe layer to prevent damage to the glass fiber grouting pipe; The back glue of glass fiber grouting pipe is easily soluble in water, and construction shall not be carried out in rainy days or wet roads; Glass fiber grouting pipe is made of grouting pipe, which is easy to irritate human skin. Construction personnel must wear protective gloves; When the grouting pipe is laid, the temperature of the road surface is required to be between . Therefore, the relative displacement trend or relative displacement will occur between the narrow two, which will then generate friction. This friction is generally called 'surface friction'. performance of grouting pipe the grouting pipe is light in weight, has strong bite force with soil or gravel, is acid-base resistant, corrosion-resistant, aging resistant and easy to construct. It has high tensile strength (- times higher than that before stretching) and low elongation (only % - % of that before stretching). It is easy to cut and connect on site (polyethylene rope or connecting rod can be used for connection), and it can also be overlapped (the grouting pipe with overlapping buckle has been developed and can be connected without other materials), and the bending effect during construction is small. However the grouting pipe has low hardness, poor mechanical damage resistance, and mechanical scars such as scratches and crushed stones will produce stress concentration, which will reduce the overall mechanical properties of the grouting pipe and the grouting pipe.

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,The Xiaobian of prestressed machines and tools reminds us that there are many forms of grouting pipes, which can be distinguished from different angles, 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, 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 it can be divided into grouting pipe relying on bearing pressure, grouting pipe relying on friction and grouting pipe relying on adhesion. Post grouting: after the shaft, basement and other structures are dug, the grouting method is used to control water damage and strengthen the stratum, which is called post grouting.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, the distribution of the internal stress field and displacement field of the reinforced soil mass is changed through the friction and embedment between the grouting pipe and the surrounding soil mass.Ajax,AjaxSupport advance small conduit,AjaxAdvance small conduit support, The grouting pipe is used to pad the bottom of the horseshoe, change the cooperation specification of the mold, and adjust the cooperation space between the lower tire and the horseshoe.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 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.
