Basement top-down construction method
The invention discloses a basement top-down construction method, which relates to the field of building construction and comprises the following steps: excavating a foundation pit; hoisting an underground stiff steel column; the top plate of the basement is poured, the steel joists are pre-buried in the top plate, and a plurality of soil sampling openings are reserved in the top plate, so that construction of the next layer is facilitated; earthwork underground excavation operation is conducted on the lower layer of the bottom plate through the soil taking opening; hoisting two underground stiff steel columns to the first underground layer; a chain block is installed on the underground stiff steel column; the underground two-section stiff steel column is hoisted through a chain block, so that the top of the underground two-section stiff steel column is in butt joint with the bottom of the underground one-section stiff steel column and is fixedly welded to the bottom of the underground one-section stiff steel column; a bottom plate of the first underground layer is poured, and a soil sampling opening is reserved in the bottom plate; the steps are repeated according to the number of layers built in the basement; when the bottommost layer of the basement is constructed, a bottom plate of the bottommost layer of the basement is formed; and blocking the soil sampling port from bottom to top. The construction method is beneficial to shortening the overall construction period of construction.
本申请公开了一种地下室逆作施工方法，涉及建筑施工领域，其步骤如下：基坑开挖；吊装地下一节劲性钢柱；浇筑地下室的顶板，其中钢托梁预埋在顶板内，顶板上预留有多个取土口，便于对下一层进行施工；通过取土口对底板下层进行土方暗挖作业；将地下二节劲性钢柱吊装至地下一层；在地下一节劲性钢柱上安装手拉葫芦；利用手拉葫芦吊装地下二节劲性钢柱，使地下二节劲性钢柱的顶部与地下一节劲性钢柱的底部对接并焊接固定；浇筑地下一层的底板，底板预留取土口；根据地下室所建层数重复上述步骤；施工到地下室的最底层时，成型地下室最底层的底板；自下而上封堵取土口。本申请有助于缩短施工的整体工期。
