The secondary grouting pipe can only be grouted once and cannot be reused.Repetitive grouting pipe can be reused for many times. Long term grouting steel flower pipe, steel flower pipe grouting,CarmenPrecision tube, pile foundation grouting pipe, grouting pipe manufacturer, old brand, price advantage and quality! Each time it is used up,CarmenSeamless pipe, the pipe core and the outer wall of the pipe shall be washed clean.

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.The grouting equipment, grouting pump and the lowered grouting pipe are connected for grouting, move the grouting pipe up or down according to the requirements to carry out the construction of the next grouting section.CarmenSeamless pipeCan share continue the rebound momentum at the end of the year,2023-09-2710:01:09The 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.

● specification: inner diameter of secondary grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: & plusmn; .mm； Length of each roll: m.According to the sequence of sectional construction along the stratum depth, 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.CarmenNynashamn,● specification: inner diameter of secondary grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: & plusmn; .mm； Length of each roll: m.
