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, that is, there is an active gap. Therefore,Grouting pipe is a kind of embedded grouting pipe system it can be protected. The piston rod can be protected by adding plastic hoses or bellows within the travel range.Denver which is used for permanent sealing of construction joints, cold 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.Causes of wrinkling: the blanking specification of pipe joint is too long.Hamburg-Harburg,DenverPile bottom 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 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.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, 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 -, 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.

It is proved by experiments that the bearing capacity of the same bored pile with and without grouting pipe is separated by %. That is why more and more bored piles and grouting pipe grouting are used more and more widely in China● advantages: Simple installation, complete set; The grouting pipe can be intercepted at the construction site according to the actual required length of the joint (it is recommended that the longest grouting outlet length should not exceed m); No special installation equipment is required; Grouting time can be arbitrarily selected; When grouting is carried out internally under proper pressure, the grouting pipe fluid can keep filling the whole pipe evenly; The system allows grouting under relatively low pressure; The grouting pressure is .-.mpa.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.Good reputation,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. 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. Low cost,DenverSmall catheter, fast time, no loss, free from climate and place constraints.Before the installation of the grouting pipe, it is necessary to check whether the processed support is vertical to the grouting pipe fitting, and correct the non vertical support; Then install the grouting pipe on the bracket and fasten it.

It has good flexibility. The pipes can be coiled when they are produced, 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.demand, transportation conditions, etc., hot press vulcanization (grouting pipe) or welding (plastic grouting pipe) shall be used. The joint appearance shall be smooth and smooth, and the tensile strength shall not be less than % of the base metal. The so-called 'overlapping' without any treatment is absolutely not allowed. All kinds of cross connection points of grouting pipes shall be made of accessories produced by our new rubber products factory, so as to ensure that on-site connection is only carried out in straight sections during construction. Flexible material with sufficient deformation capacity and good adhesion with concrete. Steel pipe, plastic pipe or steel corrugated pipe should be used as acoustic detection pipe, and its inner diameter should be ~ mm. The connection of detection pipes shall be smooth transition, the nozzle shall be more than mm higher than the pile top, and the nozzle height of each detection pipe shall be the same. The lower end of the pipe shall be closed, and the upper end shall be covered. There shall be no foreign matters in the pipe and no damage to the pipe body.The use of grouting pipes has become indispensable in modern building construction, ranging from super high-rise and high-rise buildings to multi-storey buildings and indoor decoration construction. China has a longer history of using grouting pipes. Many of China&#;s ancient buildings have been listed as world-class material and cultural heritage, because China&#;s ancient buildings are very technical in construction. In China before and in the early s, grouting pipes made of bamboo and wood were used in the construction of buildings. After the mounting bracket is welded on the surface of the grouting pipe, push the strain gauge in a stable and free state without bending and twisting; The mounting bracket and strain gauge shall be installed parallel to the support axis; When tightening the screw, pay attention to reasonably controlling the frequency of the strain gauge; The installation position of the strain gauge shall be selected at the position suitable for protection as far as possible.Denver,The important reason for the stability of the grouting pipe reinforced soil subgrade is to further verify the main principle of the grouting pipe reinforced soil subgrade treatment technology. It is to place various types of grouting pipe products inside, on the surface of the soil mass or between the layers of soil mass. Relying on the tensile characteristics of the grouting pipe, the distribution of the internal stress field and displacement field of the reinforced soil mass is changed through the friction and embedment between the grouting pipe and the surrounding soil mass.If any crack is found, it shall be repaired in time, otherwise,DenverGrouting hollow anchor manufacturer, when the joint is deformed and subjected to water pressure, 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.?The 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.
