The longitudinal overlapping width of grouting pipe and grouting pipe shall not be less than cm, fix the glass fiber grouting pipe with high-quality cement nails and fixed iron sheets with a size of mm, mm and a thickness of .mm. The fixed spacing can be determined according to the actual construction situation.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.San Antonio,The grout stop plug used in the grout stop plug grouting method is the key device to seal the grouting borehole and realize segmented grouting. A good grout stop plug should ensure normal operation under the grouting pressure of more than MPa. According to its structure and working principle, the currently used slurry stoppers can be divided into two types: mechanical type and hydraulic expansion type. Among them, mechanical slurry stoppers are relatively simple and reliable, and are widely used. - is one of several commonly used slurry stoppers.In China, the types of grouting pipes are relatively complete now, from grouting pipes and grouting pipes for Reinforcing Subgrade to glass fiber grouting pipes for highway pavement, to convex joint grouting pipes and plastic tensile grouting pipes for railway. For different road construction environments, different types of grouting pipes are selected, which can not only ensure the quality of the road but also save the cost. So what kind of application effect can the grouting pipe achieve in highway maintenance? The grouting pipe manufacturer will take you to have a look.Pra, Glass fiber grouting pipe is a semi-rigid product made of glass fiber as raw material, high-strength alkali free glass fiber through a certain warp knitting process, 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, its bending radius shall not be less than times of the diameter.The Xiaobian of prestressed machines and tools reminds us that there are many forms of grouting pipes,San Antonio50lacrimal duct, 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,San AntonioSmall conduit support, 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.

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. The concrete shall be evenly distributed, and the vibration shall be 'fast inserting and slow pulling' and slightly pumped up and down to make the concrete vibrate evenly. The vibration shall be carried out in sequence to avoid over vibration and missing vibration until the concrete surface is horizontal, no significant subsidence, no bubbles and no mortar on the surface. During vibration, grouting pipe, pipeline, embedded parts, etc.When the pipe cannot be connected due to serious blockage, the following treatment principles must be followed: when it is the first pile of a certain bridge, core drilling detection must be carried out; when it is not the first pile of a certain bridge, the construction unit shall apply for changing the detection method The low strain reflection wave method or high strain strain strain measurement method shall be used and signed by the supervisor&#;s representative and the person in charge of quality supervision before implementation; In case of pipe blockage of a bridge for many times core drilling inspection shall be carried out in due time. Common problems and answers of grouting pipe what is the pressure inside the grouting pipe?Credit guarantee, 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? It has good air tightness, low gas permeability, has strong bite force with soil or gravel, is acid-base resistant, corrosion-resistant, aging resistant and easy to construct. It has high tensile strength (- times higher than that before stretching) and low elongation (only % - % of that before stretching). It is easy to cut and connect on site (polyethylene rope or connecting rod can be used for connection), and it can also be overlapped (the grouting pipe with overlapping buckle has been developed and can be connected without other materials), and the bending effect during construction is small. However the grouting pipe has low hardness, poor mechanical damage resistance, and mechanical scars such as scratches and crushed stones will produce stress concentration, which will reduce the overall mechanical properties of the grouting pipe and the grouting pipe.

It is safe and does not need to be welded on site.Welcome calls ,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.Reusable grouting pipe: it can be used for many times,San AntonioGrouting anchor, and the grouting is not limited by time.Causes of wrinkling: the blanking specification of pipe joint is too long.San Antonio, The overhead type is a special rack installed at the bottom of the driving head and connected with the wellhead tensioning equipment. 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. 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.
