Staged construction method of river-crossing underground structure
The invention relates to the technical field of underground engineering construction, and discloses a staged construction method of a river-crossing underground structure, which comprises the following steps of: firstly, constructing a first-stage cofferdam along a revetment on one side of a river channel, draining accumulated water in the first-stage cofferdam, filling soil, then constructing a foundation pit support structure and constructing a first-stage underground main body structure, and after construction of the first-stage underground main body structure is completed, the first-stage cofferdam is removed, a second-stage cofferdam continues to be constructed in the extending direction of the first-stage underground main body structure, accumulated water in the second-stage cofferdam is removed, soil filling is conducted, a second-stage underground main body structure continues to be constructed, and the steps are repeated till all the stages of underground main body structures are connected into a whole. And chiseling off the enclosure structure between the two adjacent underground main body structures, and pouring concrete, so that the whole underground main body structures are connected into a whole. According to the construction method, the water passing area during underground engineering construction is ensured through stage construction, and the construction safety of the water passing underground structure and the safety of a main body structure after completion are ensured.
本发明涉及地下工程施工技术领域，公开了一种过河地下结构的分期施工方法，首先沿河道一侧驳岸施作一期围堰，排除一期围堰内的积水并填土，随后施作基坑围护结构并施作一期地下主体结构，待一期地下主体结构施工完成则拆除一期围堰并沿一期地下主体结构的延伸方向继续施作二期围堰，排除二期围堰内的积水并填土，继续施作二期地下主体结构，重复上述步骤直至各期地下主体结构连接为一体，凿除相邻两期地下主体结构之间的围护结构并浇筑混凝土使得整个地下主体结构连接为一体。本发明通过分期施工保证了地下工程施工时的过水面积，确保了过水地下结构的施工安全及竣工后主体结构安全。
