Double-blocking construction method in underwater grouting
The invention provides a double-plugging construction method in underwater grouting, which comprises the following steps: construction of an upper-layer plugging space: forming the upper-layer plugging space between a steel pipe sleeve and a steel pipe pile by using a fixing plate, and locally communicating the upper-layer plugging space with a grouting space above the upper-layer plugging space, the cross section area of the communication part is smaller than that of the plugging part of the upper-layer plugging space; an upper-layer plugging device is assembled, specifically, the upper-layer plugging device is assembled in the upper-layer plugging space, the upper-layer plugging device is connected with an inflation hole, and the upper-layer plugging device actively achieves plugging in the working state; a bottom sealing supporting plate is arranged in the circumferential direction between the steel pipe sleeve and the steel pipe pile, and the lower-layer plugging space is formed between the bottom sealing supporting plate and the bottom of the upper-layer plugging space; and the lower-layer passive plugging device is assembled, specifically, the lower-layer passive plugging device is fixed on the bottom sealing supporting plate through back pressure, and the passive plugging device is attached to the outer wall of the steel pipe pile.
本发明提供了一种水下灌浆中的双重封堵施工方法，包括以下步骤：上层封堵空间的施工：于钢管套和钢管桩之间，利用固定板形成上层封堵空间，所述上层封堵空间，与其上方的灌浆空间局部联通，且连通处的横截面面积小于上层封堵空间封堵处的横截面面积；上层封堵装置的装配：所述上层封堵空间内，装配上层封堵装置，上层封堵装置连接有充气孔，且上层封堵装置在工作状态下，主动实现封堵；下层封堵空间的装配：于钢管套和钢管桩之间的周向方向，设置封底托板，所述封底托板与所述上层封堵空间的底部之间，形成下层封堵空间；下层被动封堵装置的装配：于封底托板上，反压固定下层被动封堵装置，所述被动封堵装置与所述钢管桩外壁贴合。
