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.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.

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, continue to extend the drilling and grouting, steel flower pipes 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,WokaviskPrecision tube, advance small conduits, 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.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.WokaviskPrecision tubePrice shock downward, it is difficult for the professional market to rebound in the off-season,2024-02-1802:24:57● specification: inner diameter of secondary grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: & plusmn; .mm； Length of each roll: m.The secondary grouting pipe can only be grouted once and cannot be reused.

● specification: inner diameter of secondary grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: & plusmn; .mm； Length of each roll: m.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. 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,WokaviskSeamless pipe, and is more suitable for situations requiring rapid response.Wokavisk,Madingou● 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)
