● specification: inner diameter of secondary grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: & plusmn; .mm； Length of each roll: m.The secondary grouting pipe can only be grouted once and cannot be reused.

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.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,2022-10-0900:40:37Repetitive grouting pipe can be reused for many times. Long term grouting steel flower pipe, steel flower pipe grouting, pile foundation grouting pipe,ColumbiaGrouting pipe, grouting pipe manufacturer, 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.Special slings shall be used for the lifting of horizontal members such as laminated plates, and the stress at each lifting point shall be uniform to avoid fracture due to uneven stress of members. Grouting method is to put some solidified slurry into the cracks or pores of rock foundation in order to improve its physical and mechanical properties. Professional grouting pipe steel flower pipe, advance small pipe, high-pressure grouting pipe pipe shed pipe, grouting pipe factory,ColumbiaPrecision tube, high price, service, on-site settlement and honest management! The purpose of grouting is to prevent seepage, stop leakage, strengthen and correct the deflection of buildings.

● 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)A -m long orifice pipe is installed at the opening of the grouting hole to prevent possible hole collapse. At the same time,ColumbiaSeamless pipe, it plays a guiding role in drilling. During grouting, it is used to install orifice closure device to prevent slurry leakage.Columbia,Process 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.
