High pressure Grout Injection Packer: is the use of the thoery of fastening pressure ring. The head is provided with a one-way valve, can prevent the slurry at high pressure into the pour spout. Ring expansion part with rubber sleeve, diameter 13MM, diameter 14MM into the grouting hole, tighten the ring crush compression bolt, the rubber sleeve, the nozzle is fixed in the hole grouting grouting. The check valve should be in 0. Pressure above 4KN can be opened, and the grouting pressure must be higher than the value. High pressure sealing needle has four types: copper, aluminum, steel mouth mouth mouth, plastic mouth, three ring type. Is divided into a front sealing type, namely filling mouth into check valve in the inlet outlet after water intake; check, check valves located in the outlet port, depending on the specific situation to choose. Check before buying the water nozzle, can be screwed down in front of the decompression drainage, grouting to screw up again; after the water will not drain buried mouth, pressure relief, but after the completion of construction to demolition grouting nozzle construction of next working procedure. The rubber sealing part of the common grouting nozzle is 14mm, and the 14mm bit is needed. The grouting nozzle with the length of 7~8cm can be used for the compact structure, and the loose structure can be used as a grouting nozzle with a length of 10~15cm.
