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,U.S.APrecision tube, double liquid silicification method,U.S.ASteel pipe, aerated silicification method and electric double liquid silicification method.The secondary grouting pipe can only be grouted once and cannot be reused.
After the grouting hole is drilled,U.S.ASeamless pipe, install and lower the grouting pipe, grout stop plug, grouting pump and the lowered grouting pipe are connected for grouting, and the grouting is carried out according to the requirements. The grouting pump will inject the slurry into the soil. After completing the construction of one grouting section move the grouting pipe up or down according to the requirements to carry out the construction of the next grouting section.U.S.ASeamless pipeThe price trend has been rising all the way,2022-02-1718:01:10● specification: inner diameter of secondary grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: & plusmn; .mm； Length of each roll: m.● 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)
The secondary grouting pipe can only be grouted once and cannot be reused.The slurry stop plug used in the slurry stop plug grouting method is the key device to seal the grouting borehole and realize segmented grouting. A good slurry stop plug shall ensure normal operation under the grouting pressure of more than MPa. According to its structure and action principle, the currently used slurry stopper can be divided into mechanical type and hydraulic type. Among them, the mechanical slurry stopper is relatively simple and reliable and is widely used. - is several commonly used slurry stopper structures.U.S.A, steel flower pipe groutingRepetitive grouting pipe can be reused for many times. Long term grouting steel flower pipe, pile foundation grouting 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.
