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.

After the grouting hole is drilled, install and lower the grouting pipe,JoyabayPrecision tube, grout stop plug, mixer and other facilities in the hole.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.JoyabaySteel pipeThe market is depressed and the price is hard to guess,JoyabayGrouting pipe,2023-03-0600:21:30● specification: inner diameter of secondary grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: & plusmn; .mm； Length of each roll: m.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,JoyabaySteel pipe, 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.A -m long orifice pipe is installed at the opening of the grouting hole to prevent possible hole collapse. At the same time, it plays a guiding role in drilling. During grouting, it is used to install orifice closure device to prevent slurry leakage.Joyabay,At-Bashy,The secondary grouting pipe can only be grouted once and cannot be reused.
