Extra-large bridge deep foundation pit cofferdam structure and construction method thereof
The invention relates to an extra-large bridge deep foundation pit cofferdam structure and a construction method thereof.The extra-large bridge deep foundation pit cofferdam structure comprises a plurality of cofferdam units, connecting pieces and corner sealing pieces, every two adjacent cofferdam units are sealed and fixedly connected through the connecting pieces, and the corners of the cofferdam units are sealed and fixedly connected through the corner sealing pieces; each cofferdam unit comprises two steel columns, a supporting steel plate, an adjusting steel plate and an adjusting piece, one end of each steel column is vertically inserted into the bottom of the foundation pit, the supporting steel plate is fixedly connected between the two steel columns, the adjusting steel plate is vertically and slidably connected with the steel columns through the adjusting piece, the cross section of each steel column is in an L shape, and the adjusting piece is fixedly connected with the supporting steel plate. Water stop grooves are formed in the inner side of the steel column and the side, close to the steel column, of the supporting steel plate correspondingly, and water stop sealing strips are clamped in the water stop grooves. The cofferdam has the advantage that the maintenance height of the cofferdam can be conveniently adjusted.
本申请涉及一种特大桥深基坑围堰结构及其施工方法，一种特大桥深基坑围堰结构，包括多个围堰单元、连接件和拐角密封件，相邻两个所述围堰单元通过连接件密封且固定连接，所述围堰单元的拐角处通过拐角密封件密封固定连接；围堰单元包括钢柱、支护钢板、调节钢板和调节件，所述钢柱设有两个，所述钢柱一端竖直插接于基坑底部，所述支护钢板固定连接于两个钢柱之间，所述调节钢板通过调节件与钢柱竖直滑动连接，所述钢柱的横截面为L形，所述钢柱内侧与所述支护钢板靠近钢柱的一侧均开设有止水槽，所述止水槽内卡接有止水密封条。本申请具有便于对围堰的维护高度进行高度的调整的优点。
