Compared with sleeve valve pipe grouting method, the common disadvantages of grouting pipe grouting method, flower pipe grouting method and drill pipe grouting method are that it is easy to emit slurry along the pipe wall and the grouting layering effect is poor. These disadvantages are particularly prominent when using slurry with good fluidity and long initial setting time; The utility model has the advantages of simple equipment and process, good flexibility, fast construction speed, and its main purpose is to check the slurry stop effect of the slurry stop pipe head, especially the slurry stop plug.Grand caradusaGrouting pipeThe domestic price index rose in the past week,2024-04-2300:38:15● specification: inner diameter of secondary grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: & plusmn; .mm； Length of each roll: m.● specification: inner diameter of secondary grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: & plusmn; .mm； Length of each roll: m.

It is used to seal the 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 seeps into the joint, the PVC port slurry on the surface can be set to seal the joint. The appropriate grouting time can be selected at the end of concrete curing. Leakage joints can also be sealed with this. Provide long-term grouting pipe, advance small pipe, high-pressure grouting pipe, pipe shed pipe, grouting pipe factory,Grand caradusaSteel pipe, old brand, price advantage and quality guarantee! In the embedded grouting pipe, the slurry can seal the construction joint, cold joint pipe leakage and the joint between the ground wall.According to the measured water absorption of the borehole, verify the water permeability of the rock stratum, and provide professional quality assurance for grouting pipe, steel flower pipe, advance small conduit, high-pressure grouting pipe, pipe shed pipe and grouting pipe factory. During the preferential activities, new and old customers are welcome to consult to determine the grouting pressure and flow,Grand caradusaGrouting pipe, and determine the grouting slurry and its initial concentration.Grand caradusa,Haji Ganjie,The secondary grouting pipe can only be grouted once and cannot be reused.
