Grouting device for locking water of steel pipe pile cofferdam
The invention relates to a mud jacking device for locking water of a steel pipe pile cofferdam. The mud jacking device comprises a supporting frame, a mud jacking pipe, an annular air bag and an inflation pipe. The supporting frame comprises an upper supporting plate and a lower supporting plate, a certain distance is reserved between the upper supporting plate and the lower supporting plate, connecting rods are welded to the upper supporting plate and the lower supporting plate, a plurality of buckles are rotationally arranged on the edge of the upper supporting plate in the circumferential direction at equal intervals, and the lower ends of the buckles are located below the upper supporting plate and incline towards the outside of the upper supporting plate. The grouting pipe vertically penetrates through the upper supporting plate and the lower supporting plate; the annular air bag is located between the upper supporting plate and the lower supporting plate of the supporting frame and can extrude the lower end of the buckle to rotate towards the outside of the upper supporting plate in the inflated state, and the annular outer side face of the annular air bag protrudes out of the upper supporting plate and the lower supporting plate. The inflation tube penetrates through the upper supporting plate to inflate and deflate the air bag. Cement grout can be pressed into the outside of the steel pipe pile from the inside of the steel pipe pile in a high-pressure grouting mode, so that the steel pipe pile is tightly combined with a rock stratum, and the water stopping effect of the steel pipe pile cofferdam is improved.
本发明涉及一种用于锁扣钢管桩围堰止水的压浆装置，包括一支撑架、压浆管、环形气囊和充气管；所述支撑架包括上支撑板和下支撑板，上、下支撑板间有一定间距并焊接连接杆，上支撑板边缘环向等距转动设置多个卡扣，卡扣下端位于上支撑板下方并向上支撑板外倾斜；压浆管竖向贯穿上、下支撑板；环形气囊位于支撑架的上、下支撑板之间，环形气囊在充气状态下可挤压卡扣下端向上支撑板外转动，且其环向外侧面突出到上支撑板和下支撑板外；充气管贯穿上支撑板对气囊充放气。本发明可通过高压注浆方式将水泥浆液从钢管桩内压入钢管桩外，使钢管桩与岩层紧密结合，提高钢管桩围堰止水效果。
