CuselesGrouting seamless pipeWhat role does it play in the industry

The use of grouting pipes has become indispensable in modern building construction, ranging from super high-rise and high-rise buildings to multi-storey buildings and indoor decoration construction. China has a longer history of using grouting pipes. Many of China&#;s ancient buildings have been listed as world-class material and cultural heritage,CuselesAdvance small conduit in tunnel construction, because China&#;s ancient buildings are very technical in construction. In China, before and in the early s, grouting pipes made of bamboo and wood were used in the construction of buildings. After the mounting bracket is welded on the surface of the grouting pipe, push the strain gauge in a stable and free state without bending and twisting; The mounting bracket and strain gauge shall be installed parallel to the support axis; When tightening the screw, pay attention to reasonably controlling the frequency of the strain gauge; The installation position of the strain gauge shall be selected at the position suitable for protection as far as possible.The commonly used standard for grouting pipe is the inner diameter of -mm. The wall thickness of the pipe has little effect on the sound transmission, so there is generally no need to restrict the thickness of the pipe wall. However, it is OK if the pipe wall can bear the lateral pressure of new concrete, not necessarily the thicker the better.Cuseles,The comparison between the embedded detection and the on-site detection of the grouting pipe is yzed as follows: The embedded detection pipe: The pile diameter of . ~ .m should be buried with double pipes; Three pipes shall be buried with pile diameter of . ~ m; Four pipes shall be buried above the pile diameter of m. According to the specific situation of Chifeng bridge, three pipes can be buried in the pile foundation. Action mechanism of grouting pipe: the grouting pipe is a flexible material. Under the action of soil load, it is a mechanism of dispersing the force on each hole belt and forming a resultant force.Phu Khuong, The small editor of the grouting pipe reminds everyone that there should be no rust, water and other impurities when using the prestressed machinery. The working clip can be used after removing the foam in the packing box, and the grouting pipe should be properly kept. However, when the prestressed tendon is long and the grouting pipe needs to be tensioned repeatedly, it is suggested that a small amount of lubricant (e.g. anchor pulling spirit) be applied to the tapered hole of the anchor plate by the prestressed machine, but also conducive to the multiple grouting of the grouting pipe; Apply lubricant on the outer surface of the tool clip and the inner and outer surfaces of the taper hole of the anchor plate before use, and regularly remove the debris on the clip surface to make the anchor flexible. However, when the clip is cracked or the tooth surface is damaged, it needs to be replaced and can not be used again.In the process of using the acoustic pipe, it is necessary to have a detailed understanding of its installation method,CuselesSupport small conduit, so that it can be used normally and improve the application quality of the grouting pipe. In the process of installing Jiangsu acoustic measuring tube, we should pay attention to the orientation of the installation hole. As long as the device is installed in a correct hole, the Jiangsu acoustic tube can be used normally in the process of application, and the service life of Jiangsu acoustic tube can be improved. This is also the most important factor in the process of application in the future. If the hole fault is bragged about in the process of the device, the resistance of Jiangsu acoustic pipe will appear in the process of application, resulting in its damage. There is a great relationship between the accuracy of the hole and the quality after construction. In the process of construction,Cuseles42 * 4 small conduit, it is necessary to use the device according to the planned paper so that it can be used normally and improve the quality of use.In the process of application, because there will be many Jiangsu acoustic measurement pipes in the process of construction. In this way, the phenomenon of uneven stress will be formed. In the process of application, the phenomena of conflict and unusable will be formed. In order to prevent the phenomenon of surrounding each other, it is necessary to pay attention to the method of the device in the process of the device, so that it can be used normally. The grouting pipe manufacturer introduced that the product quality of the grouting pipe is relatively stable, and when the mold is finalized, it is not easy to show defects. Most of the defects of the grouting pipe appeared in the trial production period, and most of them were formed due to the unreasonable planning structure of the mold. The grouting pipe manufacturer will briefly introduce the treatment methods of defects as follows: wrinkle appearance and treatment methods. The so-called wrinkle refers to that there is a convex edge on the circular arc surface of the grouting pipe, and there is a concave appearance on the adjacent side. This kind of wrinkle is mostly in the shape of sharp ridges, some of which are straight to the nozzle, and often occur symmetrically at both ends of the center line, in the shape of 'eight'. Chengdu grouting pipe manufacturers mostly occur on the inner arc surface, and some occur on the outer arc surface.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.

Action mechanism of grouting pipe: the grouting pipe is a flexible material. Under the action of soil load, the space between the outer mold and the horseshoe surface is greater than the thickness of the pipe wall.Installation materials,Disposal method: the grouting pipe shall be shortened according to the specification.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 as to ensure that on-site connection is only carried out in straight sections during construction. Flexible material with sufficient deformation capacity and good adhesion with concrete.Grouting pipe grouting pipe manufacturer clamp type grouting pipe grouting pipe price grouting pipe spot grouting pipe specification grouting pipe model grouting pipe raw material for grouting pipe grouting pipe is processed by welded pipe or spiral steel pipe, and grouting pipe processed by seamless steel pipe is generally rare in the market. The reasons are as follows: first, in terms of price, generally, the cost of grouting pipes made by welding is relatively low which is easy for purchasers to accept. The cost of domestic products made of spiral steel pipes and seamless steel pipes is too high. Second, in terms of processing technology, welded pipes are relatively easy to process, and the equipment required is relatively simple. If spiral steel pipes and seamless steel pipes are processed, the process is relatively complex. Manufacturing process and characteristics of clamp down grouting pipe clamp down grouting pipe is a kind of grouting pipe. Because only professional hydraulic clamps are required for connection, it is also commonly called clamp down grouting pipe. The clamp grouting pipe has the following characteristics: the connection of the grouting pipe is simple, as long as the hydraulic clamp is required for connection. The grouting pipe has joints at both ends of the clamp type grouting pipe, which avoids the possibility of loosening and has good seismic resistance. Several common failures in the installation of grouting pipes always have many problems when using grouting pipes for work. In order to enable everyone to provide production to the factory normally, we have specially summarized the following failures that will occur when using grouting pipes. If you have problems in the following examples, you will know how to solve them The first point is that if the joint, nozzle or bottom of the grouting pipe is not tightly sealed, it will be blocked by cement slurry during construction. At this time, it is OK to check the sealing The second point is that the joint is misaligned or deformed during installation. At this time, we need to know that it is caused by the thin material selected. The above two points are common problems in the installation of grouting pipes that are not suitable for the current location. We&#;d better remember these points of attention, so that when they occur in the future, we will know how to deal with them to ensure a quick solution! The grouting pipe joint or the pipe orifice and the pipe bottom are not sealed tightly, so please bring in mud or cement slurry during the construction process to block the pipe: during the installation and grouting of the grouting pipe, the rebar is distorted or collided, causing the dislocation and deformation of the grouting pipe joint or the deformation of the pipe wall. The main reason for this is the selection of thin-walled grouting pipes.

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, screw 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, the rubber sealing ring deforms and fits between the two layers of pipes, playing an excellent double safety sealing effect.Excellent quality, 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.[] Middle label: refers to flange, refers to fixed cutting device, refers to tightening blade device, refers to tightening blade nut, refers to cutting rotating device, refers to cutting blade, refers to pulley and refers to bearing. performance of grouting pipe the grouting pipe is light in weight, 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, 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.Cuseles,The main elastic element of the grouting pipe is the stainless steel grouting pipe, which compensates the axial, lateral and angular direction of the pipe by the expansion and bending of the grouting pipe.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, 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, it will bring many hidden dangers. Steel grouting pipe material, which has the characteristics of thin pipe wall, steel saving, 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 existence of grouting pipe mesh restricts the lateral movement of soil. The lateral sliding deformation of the soil is limited by friction and interlocking engagement between the grouting pipe and the sand particles and the passive resistance of the sand particles to the grouting pipe, forming a good interlocking effect, so that the soil has better overall shear strength and bending stiffness.
