The secondary grouting pipe can only be grouted once and cannot be reused.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 so as to alternately carry out until the designed final grouting depth, 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,BinchPrecision tube, and then conduct secondary grouting for the full depth.The grout stop plug grouting method is generally used for Rock Fissure Grouting. The grouting pipe is provided with a grout stop plug, which can close the upper part of the grouting section. The main construction steps are as follows: the grouting hole is drilled by a rotary drill. All grouting holes in the rock stratum are required to be drilled by coring in order to find out the and distribution of rock stratum fractures. The coring rate shall reach ~ % in the rock stratum and % in the broken rock stratum. The drilling cleaning fluid is mainly clean water. If the rock is broken and the hole collapse is serious, thin mud slurry can also be used as circulating fluid.BinchPrecision tubeHow to accept the recruitment at the end of the peak season, qdm-it grouting pipe,BinchGrouting pipe, ccll-y full section grouting pipe) and repetitive grouting pipe (ccll-d grouting pipe, ccll-d full section grouting pipe)Repetitive grouting pipe can be reused for many times. Long term grouting steel flower pipe, steel flower pipe grouting, pile foundation grouting pipe, grouting pipe manufacturer,BinchSeamless pipe, old brand, price advantage and quality! Each time it is used up, the pipe core and the outer wall of the pipe shall be washed clean.
