Process flow: drill in place → Drilling → Mud injection → Run casing → Continue drilling → Slag removal → Hole cleaning → Hoist the reinforcement cage → Water jetting and bottom cleaning → Concrete conduit → Placing concrete → Catheter & rarr; The pile top reinforcement can be divided into single liquid silicification method， aerated silicification method and electric double liquid silicification method.
● 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)

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， verify the water permeability of the rock stratum and provide professional quality assurance for grouting pipe， steel flower pipe，GuichengPrecision tube， 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，GuichengSeamless pipe， and determine the grouting slurry and its initial concentration.
GuichengSeamless pipeProfessional is king2022/12/2708:46:24The 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.
The secondary grouting pipe can only be grouted once and cannot be reused.
Repetitive grouting pipe can be reused for many times. Long term grouting steel flower pipe， steel flower pipe grouting， pile foundation grouting pipe， grouting pipe manufacturer， old brand， price advantage and quality! Each time it is used up， the pipe core and the outer wall of the pipe shall be washed clean.
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.
