Two convex grooves are planned at the end of the bell end of the double seal clamp grouting pipe, and the convex grooves are equipped with sealing rings. During installation, 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, and the pipe at the kneaded part is shortened and deformed after being stressed. The outer pipe between the two convex grooves is deeply embedded into the inner pipe, and then the connection of the product is completed; After being kneaded, a rubber sealing ring is deformed and pasted between two layers of pipes, and the convex grooves are equipped with sealing rings. During installation, 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, and the pipe at the kneaded part is shortened and deformed after being stressed. The outer pipe between the two convex grooves is deeply embedded into the inner pipe and then the connection of the product is completed; After being kneaded, a rubber sealing ring is deformed and pasted between two layers of pipes, which plays a double safety sealing effect.existence, Professional sales, absolute sound detection tube price advantage, providing the most cost-effective products.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. 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, there will be a certain gap between the pile retaining wall and the surrounding soil layer, 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 resistanceBallina,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.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,existenceHollow self-propelled anchor rod manufacturer, generally, in terms of processing technology 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, welded pipes are relatively easy to process, and the equipment required is relatively simple. If spiral steel pipes and seamless steel pipes are processed, 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,existence22hollow composite anchor manufacturer, 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.When the grouting pipe is installed, and the bearing capacity of the support joint shall meet the design requirements. When connecting the grouting pipes, bolts must be installed symmetrically and tightened in sequence. Meanwhile, in order to prevent excessive deflection of the grouting pipes when axial force is applied, the deflection must be corrected to the horizontal before axial force is applied.

How to deal with the joint if the grouting pipe is installed in sections? If the grouting pipe is installed in sections, the joints must be welded. The welded joints of the section steel have been prepared in the manufacturing plant, and can be installed after the two-phase adjacent joints are aligned. After all beams are welded, anchor them according to the above steps. Install the formwork at the beam end. The formwork shall be made according to the overall dimensions of Hainan grouting pipe device and the notch of the reserved slot. The formwork shall be made quite tight to prevent mortar from flowing into the displacement control box or into the beam end gap.After checking that the installed formwork is tight and seamless, clean the reserved groove, then pour concrete and vibrate it tightly. The concrete shall have at least the same strength as the structural concrete at this place, and the grouting pipe device in Hainan shall be kept clean when pouring concrete. The grouting pipe of the spring reinforcement framework shall be bound with the bamboo frame of the reinforcement framework according to the construction rigidity of the component. After being bound into a bundle, it shall be stacked at the specified position and lifted to the abutment cross. During the reinforcement binding process, the quality and wall shall be strictly controlled according to the ship support, and the finished product shall be well protected. The injection pipe shall be placed on the top, and the embedded grouting symbol shall be buried on the formwork for positioning. The inverted formwork shall be used to install stairs and component side formworks to increase the turnover rate of the formwork as much as possible. According to the design size, the formwork shall be cut with plate shears, edge folding machines, profile training machines, etc. the blanking standards shall be used for rebar concealment and cross slab. The unqualified ones shall be rectified until they meet the construction technology. Concrete pouring Before concrete mixing, the moisture content of sand and stone shall be measured and the construction mix proportion shall be adjusted according to the test results.General treatment method: first, yze what causes the pipe blockage. For the pipe blockage of hard objects, you can poke with steel bars according to the depth, or bind a slightly thicker steel bar with steel wire rope. For the pipe blockage of soft objects, you can use the air compressor pipe to open the air compressor for blowing. Be sure to note that the water in the pipe may rush up like a fountain to pour water all over you! If it is slurry leakage and pipe plugging, there is no way to open it. We can only communicate with the testing personnel to change a testing method, such as low strain and core drilling method! Other uses of the grouting pipe: in addition to being used as a detection channel and replacing part of the reinforcement section, the grouting pipe can also be used as a pipe for grouting at the bottom of the pile. Experiments have proved that the bearing capacity of the cast-in-place pile treated with the grouting at the bottom of the pile can be greatly improved. At the same time, the grouting pipe can also be used as a channel for the defect washing and grouting treatment of the accident pile. At this time, it is necessary to take measures to punch through the pipe at the defective part to be grouted. Grouting pipe is specialized in the production of grouting pipe (ultrasonic detection pipe) for bridge pile foundation inspection. The product conforms to the industrial standard steel thin-walled grouting pipe for concrete cast-in-place pile and its use requirements (JT / T -, which was tried out by the Ministry of communications of the people&#;s Republic of China on April , It can not only meet the requirements of the standard, but also greatly improve each index, and obtain the inspection report of Hebei Road and Bridge Inspection Center.Safety and health, and the bearing capacity of the support joint shall meet the design requirements. When connecting the grouting pipes the axis deviation shall be ≤ cm, bolts must be installed symmetrically and tightened in sequence. Meanwhile, in order to prevent excessive deflection of the grouting pipes when axial force is applied, the deflection must be corrected to the horizontal before axial force is applied.The glass fiber grouting pipe has the characteristics of easy construction, high temperature resistance, corrosion resistance, low elongation, no long-term creep meeting the requirements of environmental protection, and has high tensile strength in the transverse and longitudinal directions. The strength to weight ratio of glass fiber is larger than that of steel and the tensile strength can reach kn / m, which provides sufficient strength to prevent reflection cracks. When it breaks, its elongation is less than %, it has high deformation resistance and good compatibility with asphalt mixture.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, 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, 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.

How to deal with the joint if the grouting pipe is installed in sections? If the grouting pipe is installed in sections, the joints must be welded. The welded joints of the section steel have been prepared in the manufacturing plant, and can be installed after the two-phase adjacent joints are aligned.

The concrete shall have at least the same strength as the structural concrete at this place, and the grouting pipe device in Hainan shall be kept clean when pouring concrete.safety requirements ,Disposal method: the grouting pipe shall be shortened according to the specification.Cement water glass slurry overcomes the shortcomings of single liquid cement slurry, such as long setting time,existenceAdvance small conduit tunnel, difficult control and low stone rate, improves the effect of cement grouting and expands the scope of application of cement grouting [].It is necessary to comprehensively consider the selection and configuration of grouting pipes, because there are many types of expansion joints, and correct selection is very important. Only in this way can the design of the piping system be safe, reasonable, reliable and economical.?existence, 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.When the grouting pipe is installed, the axis deviation shall be ≤ cm and the bearing capacity of the support joint shall meet the design requirements. When connecting the grouting pipes, bolts must be installed symmetrically and tightened in sequence. Meanwhile in order to prevent excessive deflection of the grouting pipes when axial force is applied, the deflection must be corrected to the horizontal before axial force is applied. The grouting pipe is padded with the front lip of the horseshoe, and the height of the saddle shaped curved surface is changed to make the pipe wall crawl and slide along the accurate saddle shaped curved surface.
