Deepwater cofferdam adjustable bottom bulkhead and construction method thereof
The invention relates to a deepwater cofferdam adjustable bottom bulkhead and a construction method thereof. The deepwater cofferdam adjustable bottom bulkhead comprises a double-wall-plate bottom bulkhead used for being fixed to a cofferdam, a sliding groove fixed to one side of the double-wall-plate bottom bulkhead and a single-wall-plate bottom bulkhead assembled in the sliding groove and capable of moving up and down along the sliding groove; the single-wall-plate bottom bulkhead and the double-wall-plate bottom bulkhead are arranged side by side; and when the double-wall-plate bottom bulkhead and the cofferdam descend to the designed bottom elevation of the cofferdam together, the single-wall-plate bottom bulkhead can move downwards to the position below the bottom face of a sealing bottom along the sliding groove. According to the deepwater cofferdam adjustable bottom bulkhead and the construction method of the deepwater cofferdam adjustable bottom bulkhead, soil pressure resistance can be achieved, the pot-bottom-shaped sealing bottom with the bottom surface arranged below the bottom of the cofferdam is subjected to bottom sealing, and the thickness of the sealing bottom canbe increased.
本发明涉及一种深水围堰可调底隔舱及其施工方法，其包括：用于固定于围堰的双壁板底隔舱；滑槽，固定于所述双壁板底隔舱的一侧；单壁板底隔舱，组装于所述滑槽，且可沿所述滑槽上下移动，所述单壁板底隔舱与所述双壁板底隔舱并列设置；当所述双壁板底隔舱与所述围堰一同下降至围堰设计底标高后，所述单壁板底隔舱可沿所述滑槽下移至封底底面以下。本发明涉及的一种深水围堰可调底隔舱及其施工方法，可同时满足抵抗土压力和封底底面设于围堰底以下的“锅底状”封底，能够增加封底的厚度。
