● 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 secondary grouting pipe can only be grouted once and cannot be reused.

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, 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.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.CanlupusSeamless pipeWide shock quotation slightly tangled,CanlupusGrouting pipe, double liquid silicification method, aerated silicification method and electric double liquid silicification method.The secondary grouting pipe can only be grouted once and cannot be reused.

A good slurry stop plug shall ensure normal operation under the grouting pressure of more than MPa. According to its structure and action principle, the mechanical slurry stopper is relatively simple and reliable and is widely used. - is several commonly used slurry stopper structures.Canlupus,CanlupusSteel pipe,Klimavichy,The secondary grouting pipe can only be grouted once and cannot be reused.
