2023-09-04 05:03:01Push the rock powder and sundries that are not washed, remain at the hole bottom, or stick to the hole wall out of the grouting range, so as to improve the bonding strength and impermeability between the slurry stone body and the fracture surface.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.KurnawakaGrouting pipeQuality Assurance,2023-09-0405:03:01● 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)● 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)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.Kurnawaka,Palestine, double liquid silicification method, aerated silicification method and electric double liquid silicification method.
