Repetitive grouting pipe can be reused for many times. Long term grouting steel flower pipe, steel flower pipe grouting, pile foundation grouting pipe, grouting pipe manufacturer, old brand,CatagoGrouting pipe, price advantage and quality! Each time it is used up, the pipe core and the outer wall of the pipe shall be washed clean.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,CatagoPrecision tube, and chemical slurry includes silicate (water glass) and high slurry. Silicification method, alkali solution method, high chemical grouting method and cement grouting method.

After the grouting hole is drilled, install and lower the grouting pipe, grout stop plug, mixer and other facilities in the hole.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.CatagoPrecision tubeDemand remains sluggish domestic average,CatagoSeamless pipe,2024-04-1913:56:11The secondary grouting pipe can only be grouted once and cannot be reused.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.
