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, and is more suitable for situations requiring rapid response.According to the sequence of sectional construction along the stratum depth, grouting can be divided into sectional downward,AseriPrecision tube, 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, so as to alternately carry out until the designed final grouting depth, 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, steel flower pipes, 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.AseriSteel pipeEnterprises should optimize product structure and improve market competitiveness,2024-04-1920:18:13The grouting mechanism includes filling grouting,AseriGrouting pipe, infiltration grouting, compaction grouting and splitting grouting. Grouting materials include granular slurry and chemical slurry. Granular slurry is mainly cement slurry, alkali solution method, high chemical grouting method and cement grouting method.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, double 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,AseriSeamless 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, thin mud slurry can also be used as circulating fluid.Aseri,Chilaw,● 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)
