Foundation treatment and cofferdam combined structure for narrow river valley covering layer
The invention provides a foundation treatment and cofferdam combined structure suitable for a covering layer of a narrow river valley, the combined structure is arranged on the narrow river valley, the narrow river valley comprises the covering layer and bed rock, and a diversion tunnel outlet and a tail water outlet are formed in the narrow river valley; the combined structure comprises an underground diaphragm wall, a connecting plate is integrally formed at the top of the underground diaphragm wall, a sub-weir is connected to the connecting plate, the upstream face of the sub-weir is a vertical face, and the downstream face of the sub-weir is a slope face. The combined structure of the underground diaphragm wall and the sub-weir is utilized, the underground diaphragm wall is embedded into the bedrock, the combined structure is overall stable, the occupied river section is reduced by 70% compared with a conventional earth rock cofferdam, the underground diaphragm wall of the diversion tunnel outlet section has a protection effect on a river water elutriation right bank covering layer foundation, and safety of a tail water outlet construction area is guaranteed. The foundation treatment and cofferdam combined structure can also be used in similar projects, such as cofferdams on covering layers, pump stations built on beach lands, water intakes, highway piers and other buildings.
本申请提供了一种适用于狭窄河谷覆盖层上的地基处理与围堰组合结构，所述组合结构设置于狭窄河谷上，所述狭窄河谷包括覆盖层、基岩，所述狭窄河谷上设置有导流洞出口和尾水出口；所述组合结构包括地连墙，所述地连墙的顶部一体成型有连接板，所述连接板上连接有子堰，子堰的迎水面为竖直面且背水面为坡面。本发明利用地连墙和子堰的组合结构，地连墙嵌入基岩，该组合结构整体稳定，侵占河道断面较常规的土石围堰减少70％，且导流洞出口段的地连墙对河水淘刷右岸覆盖层基础具有防护作用，保证尾水出口施工区域安全。地基处理与围堰组合结构也可以用于同类工程中，如覆盖层上的围堰、建在滩地上的泵站、取水口、公路桥墩等建筑物。
