The secondary grouting pipe can only be grouted once and cannot be reused.The grouting mechanism includes filling grouting, infiltration grouting compaction grouting and splitting grouting. Grouting materials include granular slurry and chemical slurry. Granular slurry is mainly cement slurry, and chemical slurry includes silicate (water glass) and high slurry. Silicification method, alkali solution method, high chemical grouting method and cement grouting method.

The slurry stop plug used in the slurry stop plug grouting method is the key device to seal the grouting borehole and realize segmented grouting. A good slurry stop plug shall ensure normal operation under the grouting pressure of more than MPa. According to its structure and action principle, the currently used slurry stopper can be divided into mechanical type and hydraulic type. Among them, the mechanical slurry stopper is relatively simple and reliable and is widely used. - is several commonly used slurry stopper structures.According to the sequence of sectional construction along the stratum depth, grouting can be divided into sectional downward, continue to extend the drilling and grouting drill section holes from top to bottom and inject section slurry. After each injection section, so as to alternately carry out until the designed final grouting depth, and then carry out re grouting from bottom to top; The sectional upward pattern is that the grouting hole is drilled to the final grouting depth at one time. All kinds of grouting pipes, steel flower pipes, advance small conduits, high-pressure grouting pipes, pipe shed pipes and the formal qualification of grouting pipe factory are welcome to inquire by telephone and sincerely invite cooperation! Grout stop shall be used for bottom-up sectional grouting; The secondary full depth grouting method is to drill the grouting hole to the final grouting depth, and then conduct secondary grouting for the full depth.BihachiSteel pipeSmall price drop, cautious merchants,2024-04-1901:20:57It is used to seal the construction joints,BihachiGrouting pipe, cold joints,BihachiSeamless pipe, 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, steel flower pipe, advance small pipe, high-pressure grouting pipe, pipe shed pipe, grouting pipe factory,BihachiSteel pipe, old brand, price advantage and quality guarantee! In the embedded grouting pipe, the slurry can seal the construction joint, cold joint, cautious merchants' >

The secondary grouting pipe can only be grouted once and cannot be reused.Push the rock powder and sundries that are not washed remain at the hole bottom, so as to improve the bonding strength and impermeability between the slurry stone body and the fracture surface.Bihachi,Bockla,● features: the grouting pipe is divided into secondary grouting pipe (ccll-y grouting pipe, qdm-it grouting pipe, ccll-y full section grouting pipe) and repetitive grouting pipe (ccll-d grouting pipe, ccll-d full section grouting pipe)
