● specification: inner diameter of secondary grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: & plusmn; .mm； Length of each roll: m.The secondary grouting pipe can only be grouted once and cannot be reused.

After the grouting hole is drilled, install and lower the grouting pipe, grout stop plug, mixer and other facilities in the hole.The grouting equipment,Santiago de veraguasGrouting pipe, grouting pump and the lowered grouting pipe are connected for grouting, and the grouting is carried out according to the requirements. The grouting pump will inject the slurry into the soil. After completing the construction of one grouting section,Santiago de veraguasPrecision tube, move the grouting pipe up or down according to the requirements to carry out the construction of the next grouting section.Santiago de veraguasGrouting pipeApplication fields and process standards,2023-11-1315:06:19● features: the grouting pipe is divided into secondary grouting pipe (ccll-y grouting pipe,Santiago de veraguasSeamless pipe, qdm-it grouting pipe, ccll-y full section grouting pipe) and repetitive grouting pipe (ccll-d grouting pipe, 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.Push the rock powder and sundries that are not washed, 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.Santiago de veraguas,Gujar Khan,The secondary grouting pipe can only be grouted once and cannot be reused.
