The grouting pipe is specially used as a channel for the depth detection of pile foundation and for structural stress calculation. The grouting pipe is a small pipe, but this small pipe meets the standard sensitivity of sound reception. As long as there is a small sound, it can measure it and accurately reflect the data on the computer or sound receiver. During the concrete pouring of cast-in-place pile, which is not considered in the structural stress calculation.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, coiling and other processes. Compared with metal textile mesh and plastic woven mesh,Turialba32lead small conduit, 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.Turialba, Provide considerate service, solve customer problems, and realize one-stop procurement.If any crack is found, it shall be repaired in time, otherwise, when the joint is deformed and subjected to water pressure the ability of the grouting pipe to resist external forces will be greatly reduced. When positioning the grouting pipe, it must be kept flat at the interface, and the grouting pipe must not be allowed to roll or kink. If it is found that there is no twist, it should be adjusted in time. When casting and fixing the grouting pipe, the deviation of the grouting pipe shall be prevented, so as not to shorten one side and affect the water stop effect. When pouring and tamping the concrete, it must be vibrated sufficiently to prevent the poor combination of the grouting pipe and the concrete from affecting the water stop effect. The grouting pipe joint must be well bonded. If the construction site conditions are available, the method of hot vulcanization connection can be used.?Lvarden,Two convex grooves are planned at the end of the bell end of the double seal clamp grouting pipe, 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, a rubber sealing ring is deformed and pasted between two layers of pipes and then the connection of the product is completed; After being kneaded, which plays a double safety sealing effect.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.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.

The length can be matched according to the construction requirements,TurialbaAdvance grouting small conduit, without loss.[] it should be noted that the above specific embodiments are only exemplary.

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, 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, the slurry will permeate, fill and compact along the side of the pile under the pressure, so as to complete the replacement of the mud skin around the pile and the filling of the gap such as greatly improving the pile side friction resistanceTrustworthy,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.

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.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.

The grouting pipe is a patented product. Compared with similar products in the market, it has higher tensile resistance and better sealing performance.Where can I find it?, 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.Application scope: This product can be widely used in subway, tunnel, swimming pool and upstream amusement park, dam, ship lock, c, reservoir and ditch, nuclear power station, primary and secondary cofferdam facilities,TurialbaAdvance support small conduit, bridges, commercial and industrial buildings, garages, stadiums, aquariums, water tanks and similar structures. Grouting channel for deformation joint, construction joint leakage maintenance and embedded water stop. Slurry pipe (theoretical weight per meter)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 ChinaTurialba,Can the stretching speed of grouting pipe be defined?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, 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.?
