In recent years, there have been frequent natural disasters, such as mountain slides, floods earthquakes, fires, etc. we are so small in the face of natural disasters that we can only devote our efforts to normal prevention and post disaster rescue. The grouting pipe can reduce the damage caused by these natural disasters.Grouting pipe is an expert in road construction. It can connect the subgrade as a whole and improve the bearing capacity of the subgrade. When encountering natural disasters, the subgrade will not be greatly damaged due to natural disasters, so that we can save more people in the rescue work. The grouting pipe can also play a great role in slope protection. The use of the grouting pipe can well prevent the landslide of mountain soil and debris flow disasters. Through many years of practical experience, it has been proved that the roads that usually use the grouting pipe are far more than the same period of projects in terms of service life and quality. Thus reducing the casualty rate. Grouting pipe is a kind of excellent geosynthetics used for Pavement Reinforcement, subgrade reinforcement and soft soil foundation reinforcement. It has become an irreplaceable material in the application of asphalt pavement reflection crack treatment. This product is a semi-rigid product made of high-strength alkali free grouting pipe, which is made of mesh base material through internationally advanced warp knitting process and surface coating treatment. It has high tensile strength and low elongation in both longitude and latitude, and has excellent properties such as high temperature resistance, low cold resistance, aging resistance and corrosion resistance. It is widely used in asphalt pavement, cement pavement and subgrade reinforcement, railway subgrade, embankment slope protection, airport runway, sand prevention and control projects. 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.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, and add more strong reflection interfaces on the sound path, which is easy to cause misjudgment.Prince George City,Advantages of grouting pipe grouting pipe is an embedded grouting pipe system, which is used for permanent sealing of construction joints, pipe seepage joints, and gaps between ground walls in concrete. It is very suitable to install grouting pipes between the joints of new and old concrete. When water penetrates into the joint, it can be sealed by injecting slurry into the PVC port set on the surface. The proper grouting time can be selected after the concrete curing. Leakage joints can also be permanently sealed in this way. 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.Jenjarum, The cooperation Specification between the saddle profile on the horseshoe of the grouting pipe and the core is too low. When the outer mold and the horseshoe surface are fitted together, the gap is larger than the thickness of the pipe wall, that is, there is an active gap. Therefore, the Chengdu grouting pipe manufacturer kneads the pipe wall to form an 'eight' shaped wrinkle. The overhead type is a special rack installed at the bottom of the driving head and connected with the wellhead tensioning equipment.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.

The following aspects shall be paid attention to during the construction of grouting pipe: when the construction personnel are binding reinforcement and erecting formwork, reliable fixation measures must be taken for the buried grouting pipe to avoid displacement during concrete pouring and ensure the correct position of the grouting pipe in the concrete. When fixing the grouting pipe, 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.?Grouting pipe is a tubular waterproof sealing material used for grouting of concrete construction joints.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.Inspection environment,It is required to ensure that at least one embedded reinforcement is firmly welded with the anchor ring of maolehan grouting pipe within every meter along the joint direction. The quality of XF type grouting pipe should be carefully checked. If deformation or inconsistent spacing between two steel beams is found, it should be repaired. If necessary, the steel beam spacing of maolehan grouting pipe shall also be adjusted according to the ambient temperature during installation. XF type grouting pipe device shall be slowly put into the groove, so that the center line of the joint coincides with the center line of the actual reserved joint, and the deviation shall not exceed mm. Meanwhile, the inner edge of the steel side beam shall be kept vertical. After the XF grouting pipe is in place, the top surface of its steel beam shall be adjusted according to the longitudinal, transverse slope and elevation to be ~ mm lower than the adjacent asphalt concrete pavement and shall not exceed the pavement elevation.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.In the process of using the acoustic pipe, it is necessary to have a detailed understanding of its installation method, 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, 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 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, 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,Prince George CityGrouting pipe grouting, 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.

Sometimes the grouting pipe is overlaid on the two sides of the horseshoe surface. Adjust the cooperation specifications of the grouting pipe at the distribution nozzle. How to avoid grout leakage during installation of grouting pipe?Superior quality,Answer: Yes, it can be protected. The piston rod can be protected by adding plastic hoses or bellows within the travel range.This seems to test what I learned in junior high school. The formula for calculating the weight per linear meter of a cylinder I learned at that time is now used. However, it may be more troublesome to calculate according to that formula. It is necessary to calculate the weight per linear meter of the outer cylinder with the formula, and then subtract the weight per linear meter of the inner space. I have a headache when I think about it! With less gossip, I&#;d better provide you with a method to correctly calculate the weight of the grouting pipe per linear meter!The bi-directional tensile plastic mesh false roof used in underground coal mine with mine grouting pipe is specially designed and manufactured for the false roof support of underground coal mining face and roadway wall support. It is made of several high molecular polymers and filled with other modifiers through heating extrusion,Prince George Citymanufacturer of composite anchor rod, molding, punching, stretching, shaping, coiling and other processes. Compared with metal textile mesh and plastic woven mesh, it has light weight, high strength, isotropy, and antistatic It is a new type of mesh grouting pipe material for underground coal mine support engineering and civil engineering.Prince George City,Prince George CitySmall conduit manufacturer,Can the piston rod of the grouting pipe be protected to avoid being bruised and accelerating leakage?Disposal method: the grouting pipe shall be shortened according to the specification.When the grouting pipe is laid, it shall be kept flat and tight without wrinkling, it shall be rolled again with a clean steel wheel roller. Most urban roads use glass fiber grouting pipes with self-adhesive. The diameter of the glass fiber grouting pipe is . ~ times of the maximum particle size of the asphalt concrete surface aggregate. The ultimate tensile strength should be greater than kN / m
