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, 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.The Xiaobian of prestressed machines and tools reminds us that there are many forms of grouting pipes, which can be distinguished from different angles, including the following. According to the type of reinforcement of the grouting pipe, it can be divided into the grouting pipe of thick reinforcement of the grouting pipe, the grouting pipe of parallel reinforcement (wire) bundle of the grouting pipe, and the grouting pipe of steel strand bundle of the grouting pipe. For thick reinforcement, one grouting pipe is generally used to anchor one reinforcement. For tendons and steel strands, a grouting pipe must anchor several steel bars or steel strands at the same time, which are often arranged in a ring or circle, or in a rectangle. Obviously, due to the different number and arrangement of prestressed reinforcement, the form and structure of grouting pipe will also be different. According to the principle of grouting pipe and transmitting pretension, it can be divided into grouting pipe relying on bearing pressure, grouting pipe relying on friction and grouting pipe relying on adhesion.Hokotenango, The grouting pipe has good flexibility. When the pipe is produced, it can be coiled, 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. It is safe and does not need to be welded on site.Urdaneta,If any crack is found, it shall be repaired in time, otherwise, 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.?It is laid in the soil, and through the bite and interlock between the grouting pipe mesh and the soil, it forms an efficient stress transmission mechanism,Hokotenango50lead small conduit, 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, which effectively changes the above shortcomings of the traditional steel plastic grouting pipe. Because of the protruding joints at the welding position, it is called convex joint steel plastic grouting pipe, polyethylene (PE) and other additives, and is extruded to form a composite high-strength tensile strip. If the surface is rough embossed, 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. 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.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,HokotenangoLeading small conduit42, which plays a double safety sealing effect.

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 grouting can be repeated many times.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 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,HokotenangoAdvance small conduit and pipe shed, its bending radius shall not be less than times of the diameter.Marketing Department,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.How heavy is a grouting pipe?The grouting pipe at the tensioning end has good anchoring energy and self anchoring energy. Grouting pipe is generally used for tensioning. The grouting pipe at the tensioning end is composed of four parts: clip,The following aspects shall be paid attention to during the construction of grouting pipe: when the construction personnel are binding reinforcement and erecting formwork anchor base plate and spiral reinforcement. The clip is the key part of the anchoring system. It is two-piece and made of high-quality alloy steel.

Can the stretching speed of grouting pipe be defined?Promise and keep promise, only the allowable part of the grouting pipe can be perforated, and the body part shall not be damaged. The grouting pipe shall be fixed according to the construction specifications required by the design. The common fixing methods are: using additional reinforcement; Fixed with special fixtures; Fix with lead wire and formwork. No matter what fixing method is adopted, the grouting pipe must be positioned accurately, without damaging the effective part of the grouting pipe, so as to facilitate concrete pouring and tamping. During the construction of the grouting pipe, there are many sharp stones and sharp edged reinforcement in the concrete, so when pouring, vibrating and positioning the grouting pipe, attention should be paid to the impact force of pouring and vibrating, so as to avoid piercing the grouting pipe due to excessive force.?[patent attachment] [description] [] is the structural diagram of the utility model; [] is a schematic diagram of the cutting blade; [] is the schematic diagram of tightening the blade nut; [] is a schematic diagram of the fixed cutting device.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, 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, etc.) and flexible reinforcement (polypropylene strip, plastic grouting pipe, warp knitted grouting pipe, etc.). Because of its high tensile strength, low elongation (≤ %), 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, dam engineering, water conservancy engineering and tunnel engineering; It has remarkable safeguard effect and good social and economic benefits against rutting and pavement cracking.Hokotenango,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, from the perspective of saving steel consumption, it is OK if the pipe wall can bear the lateral pressure of new concrete, not necessarily the thicker the better.The arrangement of the strain gauge shall be installed before the prestressing force is applied, and the bracket shall be fully cooled when the initial reading is measured; If the prestress has been applied, it must be noted in the report that the supporting axial force data reflects the change of the stress of the grouting pipe after the prestress 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.
