The secondary grouting pipe can only be grouted once and cannot be reused.● 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)

After the grouting hole is drilled, install and lower the grouting pipe, grout stop plug, mixer and other facilities in the hole.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.San Juan de la maguanaPrecision tubeThe product counter attack rose by 100 yuan, and the rising opportunity is coming2022-11-0802:08:06The secondary grouting pipe can only be grouted once and cannot be reused.The grouting mechanism includes filling grouting, infiltration grouting, and chemical slurry includes silicate (water glass) and high slurry. Silicification method, alkali solution method, high chemical grouting method and cement grouting method.

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, it plays a guiding role in drilling. During grouting, it is used to install orifice closure device to prevent slurry leakage.San Juan de la maguana,Hafizabad,● 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)
