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, and determine the grouting slurry and its initial concentration.The grout stop plug grouting method is generally used for Rock Fissure Grouting. The grouting pipe is provided with a grout stop plug, which can close the upper part of the grouting section. The main construction steps are as follows: the grouting hole is drilled by a rotary drill. All grouting holes in the rock stratum are required to be drilled by coring in order to find out the and distribution of rock stratum fractures. The coring rate shall reach ~ % in the rock stratum and % in the broken rock stratum. The drilling cleaning fluid is mainly clean water. If the rock is broken and the hole collapse is serious, thin mud slurry can also be used as circulating fluid.colonPrecision tubeWhy is it so good,2024-04-2311:40:00The grouting mechanism includes filling grouting, infiltration grouting, compaction grouting and splitting grouting.

● specification: inner diameter of secondary grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: & plusmn; .mm； Length of each roll: m.A -m long orifice pipe is installed at the opening of the grouting hole to prevent possible hole collapse. At the same time, it plays a guiding role in drilling. During grouting, it is used to install orifice closure device to prevent slurry leakage.colon,Lihinga,The secondary grouting pipe can only be grouted once and cannot be reused.
