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, high chemical grouting method and cement grouting method.● 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, remain at the hole bottom, 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.According to the sequence of sectional construction along the stratum depth, grouting can be divided into sectional downward, sectional upward and sub full depth grouting. The segmented downward type is to start from the ground, drill section holes from top to bottom and inject section slurry. After each injection section,St. Louis Steel pipe, continue to extend the drilling and grouting, 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,St. Louis Grouting pipe, 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.St. Louis Grouting pipeThe recent performance is in these three aspects,2022-08-0510:11:55The 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, 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, and determine the grouting slurry and its initial concentration.St. Louis ,St. Louis Seamless pipe,Evry on Seine,● 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)
