The research shows that the friction between the grouting pipe and the soil is also greatly related to the water content and compactness of the soil. The grouting pipe itself has a pattern, 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, 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 and the reinforcement is stable and uniform, 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.Advantages: It is connected with special hydraulic tongs, does not require preparations outside the construction site does not require any equipment, is convenient and fast ( times faster than the traditional welding method), is simple to fix the grouting pipe to the reinforcement cage, and is not affected by the bad weather.Dzyarzhynsk,DzyarzhynskTunnel leading small conduit and pipe shed,Application of full section grout discharge grouting pipe in construction sequence the full section grout discharge grouting pipe is a embedded grouting pipe system, which is used for permanent sealing of construction joints, cold joints, pipe leakage, gaps between ground walls, leakage remedial measures are mainly reserved. When leakage occurs, grouting is used to make up the leakage. The grouting material can be filled with hydrophilic epoxy resin slurry,DzyarzhynskSmall conduit manufacturer, which can seal the construction joint. The outer diameter of the grouting pipe is mm; Inner diameter mm; Pressure at % deformation > MPa; Weighing about t / M; Operating temperature < ℃.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,DzyarzhynskGrouting pipe leading small conduit, 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.?Ntungamo,Disposal method: the grouting pipe shall be shortened according to the specification.The research shows that the friction between the grouting pipe and the soil is also greatly related to the water content and compactness of the soil. The grouting pipe itself has a pattern, and is also a grid like integral geo reinforced material, and the reinforcement is stable and uniform a large deformation modulus, 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. 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 length can be matched according to the construction requirements, without loss.The so-called direct grouting method refers to the method of directly placing the grouting pipe into the soil by vibrating or drilling. According to the different forms of grouting pipes, the direct grouting method can be divided into the grouting pipe grouting method, the flower pipe grouting method, and the stop plug grouting method.Grouting pipe grouting method refers to the method of grouting directly through the nozzle at the lower part of the grouting pipe; The flower tube grouting method is a method of grouting through a grouting tube (flower tube) with multiple grouting holes on the side wall; The drill pipe grouting method refers to the method of grouting directly through the drill pipe for drilling.Among the many imported projects, the development of the production technology of automobile door and window sealing strips is the most representative. Through the introduction of sealing strip production lines from Japan, Italy, Britain and other countries, domestic manufacturers have introduced more than sealing strip production lines. In addition to pure rubber sealing strips, sealing strips of various composite structures, metal skeleton and various rubber composite sealing strips, rubber and plastic composite sealing strips can be produced. At present, the overall level of China&#;s sealing strip production technology has basically reached the level of foreign countries in the s, and has become a grouting pipe. Because some projects are not easy to detect when they are manufactured, and the quality of the grouting pipe as a channel for testing instruments has become crucial. If the quality of the grouting pipe is poor, which has the characteristics of thin pipe wall, steel saving, impermeability, pressure resistance and high strength, is generally used for post tensioned reserved holes in prestressed structures. When the grouting pipe is used, it can be directly bound to the reinforcement framework. Because the grouting pipe is very light, it is very convenient to operate. However, attention should be paid to the balance of its axis during installation.Packaging strategy, Low cost, fast time, no loss, free from climate and place constraints.Can the piston rod of the grouting pipe be protected to avoid being bruised and accelerating leakage?In the construction of some grouting pipes, after the completion of the construction of the project, because some construction personnel did not take protective measures after the completion of the grouting pipes, 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.

Can the stretching speed of grouting pipe be defined?discount, 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.Application of full section grout discharge grouting pipe in construction sequence the full section grout discharge grouting pipe is a embedded grouting pipe system, which is used for permanent sealing of construction joints, cold joints, pipe leakage, gaps between ground walls, etc. in concrete. In the treatment of construction joints, leakage remedial measures are mainly reserved. When leakage occurs, grouting is used to make up the leakage. The grouting material can be filled with hydrophilic epoxy resin slurry, which can seal the construction joint. The outer diameter of the grouting pipe is mm; Inner diameter mm; Pressure at % deformation > MPa; Weighing about t / M; Operating temperature < ℃.

When necessary, a sump shall be set near the post cast strip of the base plate in combination with the design of the basement plane drainage system to facilitate the final cleaning before the grouting pipe is cast. When advance water stop is not used, a sump shall be set, which can be set in the basement according to the above method, or set outdoors as a temporary facility. Usually, we use the waterproof scheme between the grouting pipe and the water surface or before, and there are many methods for the grouting pipe to stop water in advance. It should be noted that the design unit should participate in the review of the construction organization design of the basement, so as to determine a complete implementation scheme of advanced water stop before the excavation of the foundation pit and the pouring of the cushion. Otherwise, the design modification requirements will be put forward only when problems are found in advance water stop during construction, which will affect the integrity and rationality of the whole water stop scheme.The grouting pipe without shaft roll packaging is tapped and paid off from the inner ring in the vertical state, 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, 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.
