Anti-seepage reinforcing structure at joint of adjacent diaphragm walls and construction method of anti-seepage reinforcing structure
The anti-seepage reinforcing structure comprises a pressure relief isolation pile row, the pressure relief isolation pile row is in an arc shape, the two opposite ends of the pressure relief isolation pile row are connected to the outer sides of the two adjacent diaphragm walls correspondingly, and the two opposite ends of the pressure relief isolation pile row are connected to the outer sides of the two adjacent diaphragm walls correspondingly; the inner arc surfaces of the pressure relief isolation pile rows are arranged towards the staggered joint of the two adjacent diaphragm walls; the blocking and reinforcing composite piles are connected to the two adjacent diaphragm walls so as to block the staggered joints, and a closed-loop space is defined by the pressure relief isolation pile rows, the two adjacent diaphragm walls and the blocking and reinforcing composite piles; the dewatering well is arranged in the closed-loop space; the reverse lining walls are poured on the inner sides of the two adjacent underground diaphragm walls so as to support the two adjacent underground diaphragm walls; the enclosing purlin is arranged in the length direction of the underground diaphragm wall and poured on the upper portion of the reverse lining wall, and supporting pieces are fixedly arranged between the enclosing purlin and the other underground diaphragm walls opposite to the enclosing purlin. The problem that water cannot be effectively isolated at the peak shifting position of the diaphragm wall by adopting a traditional plugging and reinforcing method is solved.
本发明公开了一种相邻地连墙接缝处防渗加固结构及其施工方法，包括：卸压隔离桩排，卸压隔离桩排呈弧形，卸压隔离桩排的相对两端分别连接于相邻的两幅地连墙的外侧，卸压隔离桩排的内弧面朝向相邻的两幅地连墙的错位接缝处设置；封堵加固复合桩，连接于相邻的两幅地连墙以封堵于错位接缝，卸压隔离桩排、相邻的两幅地连墙和封堵加固复合桩围合形成一闭环空间；降水井，设置于闭环空间内；逆作衬墙，浇筑于相邻的两幅地连墙的内侧以支撑相邻的两幅地连墙；以及沿地连墙的长度方向设置的围檩，浇筑于逆作衬墙的上部，围檩和与围檩相对的其余幅地连墙之间固设有支撑件。本发明解决了在地连墙的错峰位置采用传统的封堵加固方法不能有效隔水的问题。
