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, and the strength grade of cement slurry shall not be lower than C. Before grouting, 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,MississaugaGrouting anchor, 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, 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, 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.However, not all grouting pipe products can achieve this effect. Some inferior grouting pipe products not only fail to achieve the expected effect in use but also have problems such as low grouting efficiency, pipe burst and pipe bending, which seriously affect the grouting effect of the grouting pipe and the progress of the whole project. The quality of grouting effect comes from the selection of high-quality grouting pipe products. Shengpeng grouting pipe is a good choice for you to choose grouting pipe products because of its high strength, awesome, simple connection and high cost performance! Grouting pipe the grouting pipe is a kind of geosynthetic material formed by ultrasonic welding, which is composed of a steel plastic composite reinforced belt (built-in high-strength carbon spring steel wire (stress material) and wrapped with polyethylene resin (protective material) and arranged at right angles to the plane longitude and latitude. It is a comprehensive product of existing rigid reinforcement (flat steel strip ribbed steel strip, galvanized steel strip, stainless steel strip, reinforced concrete strip, etc.) and flexible reinforcement (polypropylene strip, plastic grouting pipe, warp knitted grouting pipe, etc.). Because of its high tensile strength, small creep, and strong interlocking and occlusive effect on the soil, it can effectively treat the soft soil foundation, restrict the lateral displacement of the soil, overcome the uneven settlement of the soil, greatly enhance the bearing capacity of the foundation and improve the overall performance of the foundation; It can be widely used in road engineering, railway engineering, retaining structure, dam engineering, water conservancy engineering and tunnel engineering; It has remarkable safeguard effect and good social and economic benefits against rutting and pavement cracking.Mississauga, the polymer grouting materials of the machine are mainly applied to acrylamide, polyurethane, lignin, epoxy resin, unsaturated ester,MississaugaSmall conduit support, etc. Generally, when the sand particle size is ≤ . mm or the rock crack opening is ≤ . mm, and the groundwater flow rate is > mm / min, the use of organic polymer chemical grouting materials can solve the engineering problems that cannot be solved by ordinary cement slurry [].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, 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, which will lead to the decrease of the pile side friction and affect the bearing capacity of the pile When the grouting pipe is used at the pile end for grouting 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 resistanceCanning Vale, It has good air tightness, strong sealing and no leakage. 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, 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.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.

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, 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, which is not only conducive to the follow-up and anchor pulling of the working clip, 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.Scheme customization, 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, 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. It is safe and does not need to be welded on site. After the two pipes are connected by using the deformation of the grouting pipe, the kneading part of the joint is large at both ends and small in the center, so that the joint is stuck at one time, avoiding the possibility of loose union. The grouting pipe has proper stable and excellent s in terms of tensile pull-out and torque resistance, and the protrusion is circular arc with small protrusion, which is useful to avoid collision with conduits, vibrators, etc.

Grouting pipe laying and fixing of grouting pipe laying of glass fiber grouting pipe can be carried out by special equipment refitted from tractors or automobiles, or manually.The grout stop plug grouting method is generally used for Rock Fissure Grouting. The grouting pipe is provided with a grout stop plug, which can close the upper part of the grouting section. The main construction steps are as follows: the rotary drill is generally used for drilling the grouting hole. All grouting holes in the rock stratum are required to be cored for drilling so as to find out the development and distribution of fractures in the rock stratum. The coring rate should reach -% in hard rock stratum and % in broken rock stratum. The drilling cleaning fluid is mainly clean water. If the rock is broken and the hole collapses seriously, the mud slurry can also be used as the circulating fluid.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, 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.MississaugaThe 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.It is laid in the soil, and through the bite and interlock between the grouting pipe mesh and the soil, so that the local load can quickly and effectively spread to the large area of soil, so as to reduce the local failure stress and improve the service life of the project. The convex joint steel plastic grouting pipe is an upgraded product of the ordinary steel plastic grouting pipe, which changes the shortcomings of the ordinary grouting pipe, such as the small peeling force of the joint (n), the easy cracking of the welding point, the difficulty of construction, and the reduction of the role of side displacement prevention. Due to the change of material ratio and construction technology, the peeling force of the welding joint is between N and N, it is called convex joint steel plastic grouting pipe, and its academic name is node reinforced steel plastic grouting pipe. The steel plastic grouting pipe is made of high-strength steel wire (or other fibers) through special treatment, polyethylene (PE) and other additives, it is a high-strength reinforced geotextile. This single belt is woven or sandwiched at a certain distance longitudinally and horizontally, and is formed by welding its junction with the fusion welding technology of special reinforcement bonding. The grouting pipe is set out from the inner ring tap in the vertical setting out state, and the drawn out pipe forms a spring shape and stretches automatically.
