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.?When the grouting pipe is laid, it shall be kept flat and tight without wrinkling, so that the grouting pipe has effective tension. After laying, it shall be rolled again with a clean steel wheel roller. Most urban roads use glass fiber grouting pipes with self-adhesive. The diameter of the glass fiber grouting pipe is . ~ times of the maximum particle size of the asphalt concrete surface aggregate. The ultimate tensile strength should be greater than kN / m, so as to give play to the anti reflection crack performance of the glass fiber grouting pipe. It can also ensure the shear resistance and adhesive force of the adhesive layer of the glass fiber grouting pipe.Montana, Post grouting: after the shaft, tunnel, basement and other structures are dug, the grouting method is used to control water damage and strengthen the stratum, which is called post grouting.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 inner edge of the steel side beam shall be kept vertical. After the XF grouting pipe is in place, the top surface of its steel beam shall be adjusted according to the longitudinal,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, extruded and pressed, 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.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. 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,Montana50lacrimal duct, you should explain it in detail to the manufacturer in the order.Appropriate measures shall be taken to prevent surface water, 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.

They shall be connected as a whole in the factory as far as possible. If it is necessary to connect on site due to manufacturing process transportation conditions, etc., hot press vulcanization (grouting pipe) or welding (plastic grouting pipe) shall be used. The joint appearance shall be smooth and smooth, and the tensile strength shall not be less than % of the base metal. The so-called 'overlapping' without any treatment is absolutely not allowed. All kinds of cross connection points of grouting pipes shall be made of accessories produced by our new rubber products factory, so that the device can smoothly extend into the grouting pipe for cutting.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, Germany, Italy,MontanaSupport advance small conduit, Britain and other countries, up to now, 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,MontanaGrouting pipe grouting, 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.Recommendation and consultation,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 China 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.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, Germany, Italy, up to now, domestic manufacturers have introduced more than sealing strip production lines.

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, it will bring many hidden dangers. Steel grouting pipe material, 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.

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.Quality management,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 fast cutting device in the hole of the underground grouting pipe according to claim , wherein the outer diameter of the cutting rotating device is mm smaller than the inner diameter of the grouting pipe. 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.Montana,Answer: it varies according to the model and elasticity of the grouting pipe, and its internal pressure can reach bar or more.Answer: it varies according to the model and elasticity of the grouting pipe and its internal pressure can reach bar or more.How heavy is a grouting pipe?
