double liquid silicification method, aerated silicification method and electric double liquid silicification method.The secondary grouting pipe can only be grouted once and cannot be reused.

Water pressure test water pressure test is that the grouting pump injects clean water into the grouting section, and its main purpose is to check the slurry stop effect of the slurry stop pipe head, especially the slurry stop plug.After the grouting hole is drilled, install and lower the grouting pipe, grout stop plug mixer and other facilities in the hole.Bauta Steel pipeNecessity for enterprises to implement service strategy, qdm-it grouting pipe, ccll-y full section grouting pipe) and repetitive grouting pipe (ccll-d grouting pipe, ccll-d full section grouting pipe)● features: the grouting pipe is divided into secondary grouting pipe (ccll-y grouting pipe,Bauta Steel 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)

● specification: inner diameter of secondary grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: & plusmn; .mm； Length of each roll: m.Push the rock powder and sundries that are not washed,Bauta Grouting pipe, remain at the hole bottom,Bauta Precision tube, or stick to the hole wall out of the grouting range, so as to improve the bonding strength and impermeability between the slurry stone body and the fracture surface.Bauta Sadao,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.
