Deep foundation pit trestle post-dismantling construction method
The invention discloses a deep foundation pit trestle post-dismantling construction method which comprises the steps that 1, a first support and a trestle plate are deeply designed, and the trestle plate is located above the ground; 2, a first layer of earthwork is excavated, a first support is constructed, and a trestle plate is laid; 3, the trestle plate is temporarily lifted away, a second layer of earthwork is excavated, and a second support is constructed; 4, the last layer of earthwork is excavated, and a basement bottom plate is constructed; 5, dismantling the second support, and constructing a B2 layer structure of the basement; 6, a basement B1 layer structure is constructed; 7, unneeded angle braces and trestle plates are dismantled, and most of the trestle plates are reserved; 8, a basement top plate is constructed below the first support and the trestle plate; and 9, constructing an overground structure, wherein trestle plates serve as temporary roads and storage yards of the site. The invention relates to the technical field of foundation pit construction, and can solve the problems that in the prior art, concrete trestle plates interfere with excavation and transfer of earthwork below, the concrete trestle plates affect transportation on the ground after being dismantled, and basement roofs crack due to premature use.
本发明公开了一种深基坑栈桥后拆除施工方法，包括步骤：1、深化设计首道支撑和栈桥板，栈桥板位于地面上方；2、开挖第一层土方，施工首道支撑，铺设栈桥板；3、临时吊开栈桥板，开挖第二层土方，施工第二道支撑；4、开挖最后一层土方，施工地下室底板；5、拆除第二道支撑，施工地下室B2层结构；6、施工地下室B1层结构；7、拆除不需要的角撑和栈桥板，保留大部分的栈桥板；8、在首道支撑和栈桥板的下方施工地下室顶板；9、施工地上结构，栈桥板作为场地临时道路及堆场。本发明涉及基坑施工技术领域，能够解决现有技术中混凝土栈桥板干涉下方土方开挖和转运、混凝土栈桥板拆除后影响地上运输、地下室顶板过早使用而开裂的问题。
