Sukarno hada International AirportSeamless pipe,

● 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,Sukarno hada International AirportGrouting pipe, ccll-d full section grouting pipe)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 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,Sukarno hada International AirportSteel pipe, 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, and determine the grouting slurry and its initial concentration.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.Sukarno hada International AirportGrouting pipeStrong cost and strong sentiment, qdm-it grouting pipe, ccll-d full section grouting pipe)

The secondary grouting pipe can only be grouted once and cannot be reused.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.Sukarno hada International Airport,Tutrakan,● specification: inner diameter of secondary grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: & plusmn; .mm； Length of each roll: m.
