● features: the grouting pipe is divided into secondary grouting pipe (ccll-y grouting pipe, qdm-it grouting pipe,ColumbiaSteel 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, 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.Push the rock powder and sundries that are not washed, remain at the hole bottom,ColumbiaSeamless pipe, 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.ColumbiaPrecision tubeReasonable price guidelines2024-04-2722:09:44Special slings shall be used for the lifting of horizontal members such as laminated plates, and the stress at each lifting point shall be uniform to avoid fracture due to uneven stress of members. Grouting method is to put some solidified slurry into the cracks or pores of rock foundation in order to improve its physical and mechanical properties. Professional grouting pipe, steel flower pipe, advance small pipe, high-pressure grouting pipe, pipe shed pipe, grouting pipe factory, high price, service, on-site settlement and honest management! The purpose of grouting is to prevent seepage, stop leakage, 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.

● specification: inner diameter of secondary grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: & plusmn; .mm； Length of each roll: m.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,ColumbiaPrecision tube, new and old customers are welcome to consult to determine the grouting pressure and flow, and determine the grouting slurry and its initial concentration.Columbia,The secondary grouting pipe can only be grouted once and cannot be reused.
