Adjust the cooperation specifications of the grouting pipe at the distribution nozzle. How to avoid grout leakage during installation of grouting pipe?San Juan de la maguana,Reusable grouting pipe product specification: inner diameter: mm; Outer diameter: mm; Inner diameter tolerance: ± .mm; Length of each roll: m. Grouting pipe at tensioning end: the grouting pipe installed at the end of the grouting pipe reinforcement and capable of tensioning is also called grouting pipe grouting pipe. The so-called grouting pipe is a grouting pipe in post tensioning structure or component to maintain the tension of the grouting pipe reinforcement and transmit it to the mixed tension; Fixed end grouting pipe: a grouting pipe installed at the end of the grouting pipe reinforcement and usually buried in the concrete without tensioning. The standard of the grouting pipe used for the grouting pipe reinforcement is the national standard of the people&#;s Republic of China (GB / T -, which ensures that the products manufactured by our company conform to the product quality law of the people&#;s Republic of China and the standard law of the people&#;s Republic of China Grouting pipe is the only acoustic pipe specially used for ultrasonic testing in the market. The grouting pipe is made of cold and hard steel pipe after professional molding, and is connected by clamp pressure connection, flange connection and other methods. It has a reliable anti-seepage effect during concrete pouring. Two convex grooves are planned at the end of the bell end of the high-strength double seal clamp type acoustic measuring pipe, and the convex grooves are equipped with sealing rings. When installing the device, the socket end of the product is stabbed into the bell end by cm, and then the two convex grooves are kneaded together with special hydraulic pliers. The pipe at the kneaded part is shortened and deformed after being stressed, and the outer pipe between the two convex grooves is deeply immersed into the inner pipe, and then the reliable connection of the product is completed; After being kneaded, the rubber sealing ring deforms and fits between the two layers of pipes, playing an excellent double safety sealing effect.London,The mesh structure of the grouting pipe can make the pore water pressure dissipate faster, and effectively accelerate the drainage and consolidation of the soft soil of the foundation. This is very important for strengthening soft clay foundation. Precautions for grouting pipe installation: when tensioning the prestressed reinforcement, it shall be loaded from zero to the initial tension at the starting point of the measured elongation value and then loaded to the required tensioning force by stages; Stress control and elongation check shall be adopted for tensioning management of prestressed reinforcement. The allowable deviation between the actual elongation value and the calculated elongation value is - % ～ + %. If the value is exceeded, the tensioning shall be suspended; Tensioning can be continued only after taking measures to adjust; If the elongation value is too small, over tensioning measures can be taken, but the tensioning force limit shall not be greater than .fptk; In the multi wave curve prestressed reinforcement, in order to increase the tensile stress at the inner support and reduce the tensile stress at the lower mouth of the grouting pipe after tensioning, the technology of over tensioning and loosening can be adopted; The duct grouting shall be dense, the duct shall be wet and clean, the grouting shall be carried out slowly and evenly without interruption, and the exhaust shall be smooth. If the hole is blocked, the grouting port must be replaced, but the cement slurry injected for the first time must be discharged to avoid gas between the two grouts. After the holes are filled and the exhaust holes are closed, the pressure should be increased to .-.mpa, and the grouting holes should be closed later. The grouting pressure of the vertical duct shall be determined according to the grouting height; For the duct grouting of multi span continuous prestressed tendons connected by connectors, one span shall be grouted after tensioning, and it is not allowed to grout once after all the spans are tensioned; The exposed length of the prestressed reinforcement grouting pipe after fixation shall not be less than mm, and the grouting pipe shall be protected with end sealing concrete. When it needs to be exposed for a long time, measures to prevent corrosion shall be taken; When the steel strand has floating rust, please remove the floating rust and dirt of the steel strand at the fixed clamping section of the grouting pipe and its outer end, so that the floating rust and dirt will fill the red groove of the clamping piece during installation and tensioning and cause wire sliding; The tool clamping piece is three pieces and the working clamping piece is two pieces. The two cannot be mixed. The working grouting pipe cannot be used as a tool and the grouting pipe cannot be reused; The grouting pipe shall be kept properly and shall be free of rust, water and other sundries during use. The working clip can be used after removing the foam in the packaging box. However, when the prestressed tendon is long and the grouting pipe must be repeatedly tensioned and fixed it is recommended to apply a small amount of lubricant (such as withdrawing the grouting pipe) in the conical hole of the grouting pipe plate, which is not only conducive to the follow-up of the working clip and withdrawing the grouting pipe, but also conducive to the multiple grouting pipe fixation of the grouting pipe; The outer surface of the tool clip and the inner surface of the conical hole of the grouting tube plate shall be coated with lubricant before use, and the debris on the clip surface shall be removed frequently to make the grouting tube flexible. However,San Juan de la maguanaGrouting pipe, when the clip is cracked or the tooth surface is damaged, it shall be replaced and shall not be used again; Safety measures shall be taken during tensioning, and no one shall stand after tensioning the jack; The grouting pipe solid system shall be used together and shall not be mixed with other systems. If the static load test is to be conducted, please clean the clamp with organic solvent (such as gasoline) and wipe the anti rust oil of the grouting tube plate hole,San Juan de la maguanaAdvance support of small conduit, otherwise the solid performance of the grouting tube will be affected; The pile foundation grouting pipe is an important channel product for pile foundation depth detection. It has two main s, one is as a channel, and the other is as a pipe for grouting at the bottom of the pile.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, heated and stretched, 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.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, 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,San Juan de la maguanaSmall conduit manufacturer, and has become a grouting pipe. Because some projects are not easy to detect when they are manufactured, 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, double liquid silicification, aerated silicification and electric double liquid silicification. It is applicable to the laying of buried pipes in gas pipeline projects, and is not applicable to the use of open pipes. The service life of pipes will be affected by the perennial ultraviolet corrosion of sunlight. How to use the grouting pipe after rusting will not affect its . The grouting pipe is a kind of rubber plate we often see. It is widely used and has a long service life. It has been praised and recognized by people. Next, I will introduce the relevant knowledge of the grouting pipe we produce in detail!OK or not?,Answer: it varies according to the model and elasticity of the grouting pipe, and its internal pressure can reach bar or more. It has good flexibility. The pipes can be coiled when they are produced, so that the number of joints in the pipe network can be reduced. It can be laid according to the terrain, easily bypass obstacles, and is convenient for construction.At the same time, the relative displacement trend or relative displacement also occurs between this part of soil particles and adjacent soil particles, resulting in friction. This friction force is generally called 'bite force' or 'lateral force resistance'. The 'surface friction' and 'bite force' make the slip and roll of soil particles under the force of the upper limit line at the location of the grouting pipe, and limit the lateral displacement of soil in the whole plane of the grouting pipe. The grouting pipe plays an important role in the key points of settlement. Therefore, it is reasonable to use the grouting pipe to treat the uneven settlement of fill excavation transition subgrade. This paper yzes the action mechanism of the grouting pipe according to its type and characteristics introduces the construction technology and process in the construction of preventing the reflection crack of the road surface, and proposes a new technology of sprinkling a layer of filler in the grouting pipe network when paving the surface course. As a kind of road reinforcement material, grouting pipe is widely used in road maintenance engineering because of its advantages of simple, fast construction and low investment.
