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, its bending radius shall not be less than times of the diameter. The quality of the steel upsetting head of the grouting pipe is not directly related to its own quality, but the excessive strength will be harmful to the quality of the upsetting head. Therefore, when you choose the upsetting head anchor you should explain it in detail to the manufacturer in the order.Answer: according to the length and diameter, the weight of common grouting pipe is . ~ .KG, and the weight can reach several kilograms.Application scope and development space of grouting pipe as a new term, grouting pipe has gradually appeared in some online newspapers and periodicals, and its practical scope has also developed from the support of some basic automobile boot and engine cover to the machinery manufacturing industry, used for the support of equipment accessories, vibration reduction of equipment, support of tool box cover, medical industry, fitness equipment and other fields. As its practicality is further recognized its scope of application is becoming wider and wider. Some people in the industry asked: the application range of grouting pipe is becoming wider and wider. Does it have an impact on the original telescopic spring? In my personal opinion, it will not impact the original spring. Of course, it will have a certain impact, because most of the grouting pipes are innovations in the product design of some enterprises. For example, the rear box of a tricycle was originally supported by an iron bar (which is still useful). Now, the grouting pipe is very light, convenient and labor-saving. Some units do not know it, so its design has certain limitations, However, and they have been officially used, with obvious effects. However, some enterprises do not know what the grouting pipes are, let alone their s, so they will be in a passive position. Therefore, we hope that some industries,MansaraAdvance small conduit support, such as machinery manufacturing, automobile and motorcycle, transportation equipment, box manufacturing such as tool boxes, fitness, kitchen cabinets, etc, If you need to know the and use of the grouting pipe, please feel free to consult me, and I will give you adviceMansara, without loss.Mahalapye,The glass fiber grouting pipe has the characteristics of easy construction, high temperature resistance, corrosion resistance, low elongation, high elastic modulus, 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.In the engineering practice, some construction units directly pave the glass fiber grouting pipe after spraying the sticky layer oil, and the roller rolls after it. The effect is good, and the glass fiber grouting pipe is not easy to wave. Strictly control the entry and exit of vehicles transporting the mixture, brake and dump the leftover mixture on the grouting pipe layer to prevent damage to the glass fiber grouting pipe; The back glue of glass fiber grouting pipe is easily soluble in water, and construction shall not be carried out in rainy days or wet roads; Glass fiber grouting pipe is made of grouting pipe, which is easy to irritate human skin. Construction personnel must wear protective gloves; When the grouting pipe is laid, the temperature of the road surface is required to be between . Therefore, the relative displacement trend or relative displacement will occur between the narrow two, which will then generate friction. This friction is generally called 'surface friction'.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.

Action mechanism of grouting pipe: the grouting pipe is a flexible material. Under the action of soil load, and each loop is m according to the paper requirements. Put the outer layer of fabric into the blue horn interface to try the tensile property and confirm that it has been inserted to the end. The other end of the horn is sleeved with a PVC reinforced grouting pipe. It pipes shall be arranged according to the direction of construction joints, and installed mm away from the back water surface. Note that the green it pipe itself cannot be exposed to the concrete to be poured, and ensure that the PVC pipe is exposed outside the concrete for grouting in the future. Cement nail fixing clips or iron wires shall be used for fixing every other distance, and the distance between two fixing points shall be ≤ cm. The ends of it pipes of two adjacent circuits must overlap by at least cm. The exposed PVC pipe is installed in the grouting interface box to facilitate grouting in the future.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,MansaraSmall catheter, 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 resistanceProfessional is king, 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 -,Mansara50lead small conduit, 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. The grouting pipe is used to pad the bottom of the horseshoe, change the cooperation specification of the mold, and adjust the cooperation space between the lower tire and the horseshoe. The grouting pipe is a patented product. Compared with similar products in the market, it has higher tensile resistance and better sealing performance.

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, 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.ranking,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. Push the rock powder and sundries that have not been washed, remain at the bottom of the hole, or stick to the hole wall beyond the grouting range, so as to improve the bonding strength and impermeability of the slurry stone body and the fissure surface.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.Mansara,Plastic pipe plastic pipe has a low acoustic impedance which is used as a grouting pipe and has a large acoustic transmission rate. It can usually be used for smaller cast-in-place piles. It should be cautious when used in large-scale cast-in-place piles - because large-diameter piles need to be poured with a large amount of concrete, and the hydration heat of cement is not easy to dissipate. In view of the great difference between the thermal expansion coefficient of plastic and concrete, the plastic pipe will shrink radially and longitudinally due to the temperature drop after concrete solidification, It may be separated from the concrete locally to cause air or water crevices, and add more strong reflection interfaces on the sound path, which is easy to cause misjudgment.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, which is used as a grouting pipe and has a large acoustic transmission rate. It can usually be used for smaller cast-in-place piles. It should be cautious when used in large-scale cast-in-place piles - because large-diameter piles need to be poured with a large amount of concrete, and the hydration heat of cement is not easy to dissipate. In view of the great difference between the thermal expansion coefficient of plastic and concrete, the plastic pipe will shrink radially and longitudinally due to the temperature drop after concrete solidification, It may be separated from the concrete locally to cause air or water crevices, and add more strong reflection interfaces on the sound path, which is easy to cause misjudgment.
