The bottom of the horseshoe of the grouting pipe is too low. After the horseshoe is seated in the mold, the space between the outer mold and the horseshoe surface is greater than the thickness of the pipe wall.There are many forms of grouting pipes that can be improved and applied. Although the engineering pipeline system is very complex, any complex pipe system can be divided into several relatively simple individual pipe sections through the setting of fixed pipe racks. When selecting the corrugated grouting pipe, the deformation compensation of the pipe system can be determined according to these relatively simple pipe sections, so as to select the grouting pipe.Remidos Good advantages of steel origin and convenient transportation enable us to meet customer requirements efficiently and quickly.The use of grouting pipes has become indispensable in modern building construction, because China&#;s ancient buildings are very technical in construction. In China 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, 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.Gao Kai, 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.In limestone area, and it is difficult to sink the reinforcement cage. When the grouting pipe is deformed and blocked by unconventional means, the pipe is blocked due to the workers&#; carelessness and falling into small concrete blocks. The deformation and blockage of the grouting pipe bring great difficulties to the detection work, and even can not be detected. Therefore, when the grouting pipe is found blocked after the foundation pile is poured and before the inspection, effective measures should be taken to pass the pipe to ensure the smooth progress of ultrasonic inspection. Generally, there are three methods for passing the pipe: stabbing the grouting pipe with thick and long reinforcement, 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 plays a double safety sealing effect.

A short section of screw end rod is welded on both ends of a single prestressed thick steel bar, and the nut and backing plate are sleeved to form the simplest grouting pipe. The pretension force is transmitted to the nut through the bearing force on the threaded slope of the screw end rod, and then to the concrete components around the reserved hole crossing through the base plate.Let&#;s take a look at the prestressed machines and tools. The small editor of prestressed machines and tools reminds everyone that the screw end rod is made of cold drawn or heat-treated reinforcement, and the thread is fine teeth. The welding between the end rod and the prestressed reinforcement should be carried out before the cold drawing of the prestressed reinforcement. This grouting pipe can be used at the tensioning end and the fixed end. A general jack is used for tensioning, and the jack pull rod (with internal thread at the end) is tightened on the thread of the screw end rod for tensioning. After tensioning, tighten the nut and anchor the rebar. The advantages of this grouting pipe are relatively simple,RemidosSelf propelled hollow grouting anchor manufacturer, and when the jack returns oil after the grouting pipe, the prestressed reinforcement basically does not slide. If necessary, facilitate re tensioning. The disadvantage is that the accuracy of the length of prestressed reinforcement is high, and it cannot be too long or too short, complete supply; The grouting pipe can be cut 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 the inner grouting is performed under pressure, the slurry in the grouting pipe can keep filling the whole pipe evenly; The system allows grouting at relatively low pressure; The installation will not affect the characteristics of the building grouting pipe itself; The installation or grouting process will not harm the concrete; Permanent sealing can be ensured after grouting; If there is no leakage, grouting can be omitted.Answer: it varies according to the model and elasticity of the grouting pipe, and its internal pressure can reach bar or more.Welcome calls ,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,RemidosAdvance small conduit tunnel, the deflection must be corrected to the horizontal before axial force is applied.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, 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, 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, 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. The saddle shaped curved surface on the horseshoe surface of the grouting pipe and the upper and outer molds are not well fitted, which is caused by the Chengdu grouting pipe manufacturer&#;s failure to smooth (flatten) the grouting pipe along the horseshoe surface.

Answer: Yes, The overhead type is a special rack installed at the bottom of the driving head and connected with the wellhead tensioning equipment.After the sodium hydroxide solution is poured in, the calcium chloride solution is poured in, which is called the two liquid method. Alkali solution method has the advantages of simple construction equipment, low reinforcement cost, and elimination of collapsibility of loess. The grouting pipe is specially used as a channel for the depth detection of pile foundation and for structural stress calculation. The grouting pipe is a small pipe, but this small pipe meets the standard sensitivity of sound reception. As long as there is a small sound, it can measure it and accurately reflect the data on the computer or sound receiver. During the concrete pouring of cast-in-place pile a channel that allows the ultrasonic probe to be normally placed at the pile bottom is reserved, which is not considered in the structural stress calculation.Remidos,At the same time, because the space in the grouting pipe restricts the lateral sliding and rolling of the soil particles inside, the relative displacement trend or relative displacement also occurs between this part of soil particles and adjacent soil particles, resulting in friction. This friction force is generally called 'bite force' or 'lateral force resistance'. The 'surface friction' and 'bite force' make the slip and roll of soil particles under the force of the upper limit line at the location of the grouting pipe, and limit the lateral displacement of soil in the whole plane of the grouting pipe. The grouting pipe plays an important role in the key points of settlement. Therefore, it is reasonable to use the grouting pipe to treat the uneven settlement of fill excavation transition subgrade. This paper yzes the action mechanism of the grouting pipe according to its type and characteristics, introduces the construction technology and process in the construction of preventing the reflection crack of the road surface, and proposes a new technology of sprinkling a layer of filler in the grouting pipe network when paving the surface course. As a kind of road reinforcement material, grouting pipe is widely used in road maintenance engineering because of its advantages of simple,RemidosSupport advance small conduit, fast construction and low investment.Welding is strictly prohibited during use, because the strength of the welding point is much lower than that of the steel itself, 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. The grouting pipe is specially used as a channel for the depth detection of pile foundation and for structural stress calculation. The grouting pipe is a small pipe, but this small pipe meets the standard sensitivity of sound reception. As long as there is a small sound it can measure it and accurately reflect the data on the computer or sound receiver. During the concrete pouring of cast-in-place pile, a channel that allows the ultrasonic probe to be normally placed at the pile bottom is reserved, which is not considered in the structural stress calculation.
