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, ccll-y full section grouting pipe) and repetitive grouting pipe (ccll-d grouting pipe, ccll-d full section grouting pipe)

Compared with sleeve valve pipe grouting method,Lhasa LudeGrouting pipe, the common disadvantages of grouting pipe grouting method, flower pipe grouting method and drill pipe grouting method are that it is easy to emit slurry along the pipe wall and the grouting layering effect is poor. These disadvantages are particularly prominent when using slurry with good fluidity and long initial setting time; The utility model has the advantages of simple equipment and process, good flexibility, fast construction speed, and is more suitable for situations requiring rapid response.Compared with sleeve valve pipe grouting method, the common disadvantages of grouting pipe grouting method, flower pipe grouting method and drill pipe grouting method are that it is easy to emit slurry along the pipe wall and the grouting layering effect is poor.

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, alkali solution method high chemical grouting method and cement grouting method.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.Lhasa Lude,San Antonio The secondary grouting pipe can only be grouted once and cannot be reused.
