● specification: inner diameter of secondary grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: & plusmn; .mm； Length of each roll: m.Repetitive grouting pipe can be reused for many times. Long term grouting steel flower pipe, steel flower pipe grouting, pile foundation grouting 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.

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.After the grouting hole is drilled install and lower the grouting pipe, grout stop plug, mixer and other facilities in the hole.LibertaborgPrecision tubeAt present, the development of manufacturing process is slow,LibertaborgSeamless pipe,LibertaborgPrecision tube, and the breakthrough of technology has not been achieved,2023-03-3001:33:51Process flow: drill in place → Drilling → Mud injection → Run casing → Continue drilling → Slag removal → Hole cleaning → Hoist the reinforcement cage → Water jetting and bottom cleaning → Concrete conduit → Placing concrete → Catheter & rarr; The pile top reinforcement can be divided into single liquid silicification method, double liquid silicification method, aerated silicification method and electric double liquid silicification method.● 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, and chemical slurry includes silicate (water glass) and high slurry. Silicification method, alkali solution method, 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,LibertaborgGrouting pipe, thin mud slurry can also be used as circulating fluid.Libertaborg,Angeles,The secondary grouting pipe can only be grouted once and cannot be reused.
