Advancing type localized double-liquid grouting device and construction method
The invention discloses an advancing type localized double-liquid grouting device and a construction method. The device comprises a hole sealing grouting opening, an auxiliary sleeve and a grouting pipe. The grouting pipe is detachably connected to the hole sealing grouting opening. The grouting pipe with the hole sealing grouting opening is inserted in the auxiliary sleeve. The auxiliary sleeve is connected with the hole sealing grouting opening through a flange. The length of the grouting pipe is larger than that of the auxiliary sleeve so that deep localized grouting can be achieved. The advancing type localized double-liquid grouting device and the construction method have the advantages that the grouting pipe is simple in structure and suitable for being manufactured on site; the grouting device and the technological process are simple, and operation is easy and convenient; the price of PVC pipes is relatively low and construction cost is greatly saved; domain controlled grouting can be achieved, it is ensured that a stratum is uniformly reinforced, no blind point exits, and disasters are avoided; grouting can be repeatedly conducted, point selecting and hole opening are prevented from being conducted again, the construction period is shortened, and economic benefits are high; the application range is wide, and the advancing type localized double-liquid grouting device and the construction method are suitable for all engineering type soft stratums needing to be reinforced.
