Foundation pit support structure and construction method thereof
The invention discloses a foundation pit support structure and a construction method thereof, relates to the technical field of geotechnical engineering foundation pit support, and provides the foundation pit support structure with good water stop effect. The foundation pit support structure comprises foundation pit fender posts and at least one water stop structure arranged between the foundationpit fender posts, wherein the water stop structure comprises a steel plate, a flexible rubber water stop plate and a pile head; the flexible rubber water stop plate comprises a vertical plate and negative lock catches positioned at the two sides of the vertical plate; the top end of the steel plate is provided with a bending part; the pile head comprises a triangular cone structure, and a steel plate limiting slot is formed above the triangular cone structure; the two ends of the pile head are provided with connecting parts which are matched with the negative lock catches; the lower end of the steel plate is inserted into a steel plate limiting slot; the upper end of the vertical plate is embedded into the bending part of the steel plate; the lower end of the vertical plate is fixedly connected to the triangular cone structure; the negative lock catches of the flexible rubber water stop plate are sleeved by the connecting part of the pile head; and the negative lock catches of the flexible rubber water stop plate are in matched connection to positive lock catches of the fender posts. The water stop curtain does not need to additionally arrange for foundation pit engineering with water interception requirements, so that the manufacturing cost is effectively reduced.
本发明的一种基坑支护结构及其施工方法，涉及岩土工程基坑支护技术领域，用于提供一种止水效果好的基坑支护结构。它包括基坑围护桩以及设置于其之间的至少一道止水结构，止水结构包括钢板、柔性橡胶止水板和桩头，柔性橡胶止水板包括竖向板和位于其两侧的阴锁扣，钢板顶端设有折弯部，桩头包括三角锥结构、其上方有钢板限位槽，桩头两端设有与阴锁扣配合设置的连接部，钢板下端插入钢板限位槽内，竖向板上端嵌入钢板的弯折部内，竖向板的下端与三角锥结构固定连接，柔性橡胶止水板的阴锁扣套设于桩头的连接部内，柔性橡胶止水板的阴锁扣与基坑围护桩的阳锁扣配合连接。对于有截水要求的基坑工程无需再另设止水帷幕，有效的降低了造价。
