Cofferdam backfill consolidation foundation and construction method
The invention provides a cofferdam backfill consolidation foundation, and relates to the technical field of cofferdam consolidation. The cofferdam backfill consolidation foundation comprises steel sheet piles, a gravel water collecting layer, a water guiding pipe, a plurality of drainage plates and pipe piles, wherein the lower parts of the steel sheet piles extend into a soft soil foundation to form a cofferdam, the gravel water collecting layer is arranged in the cofferdam, the water guiding pipe is arranged at the bottom of the gravel water collecting layer, the drainage plates are distributed in the cofferdam and are connected with vacuum extraction equipment, and the pipe piles are arranged in the cofferdam. According to the cofferdam backfill consolidation foundation, the closed cofferdam is formed through the steel sheet piles, the pipe piles are arranged on a bottom layer of the soft soil foundation, the bottom supporting strength of the soft soil foundation is enhanced, the gravel water collecting layer is laid on the surface layer of the soft soil foundation and has a good water collecting effect, muddy water is guided to the outside of the cofferdam through the water guiding pipe penetrating through the cofferdam, and vacuum extraction of water in the soft soil foundation is achieved through the combined action of the drainage plates and the vacuum extraction equipment, the water content of the soft soil foundation is reduced to the maximum extent, and the stress stability of the foundation is improved.
本发明提供了一种围堰回填加固地基，涉及围堰加固技术领域，包括钢板桩、砾石集水层、导水管、若干个排水板以及管桩；钢板桩下部延伸至软土地基中以形成围堰；砾石集水层设置于围堰内；导水管设置于砾石集水层的底部；排水板分布于围堰内，且连接有真空抽提设备；管桩设置于围堰内。本发明提供的围堰回填加固地基，利用钢板桩形成封闭的围堰，在软土地基的底层设置管桩，增强了软土地基的底部支撑强度，砾石集水层铺设在软土地基的表层，具有良好的集水作用，借助贯穿围堰设置的导水管将泥水导送至围堰的外部，再利用排水板和真空抽提设备的共同作用，实现软土地基内部水分的真空抽提，最大限度地降低软土地基的含水率，提高地基的受力稳定性。
