Super high-rise full reverse construction method
The invention relates to a super high-rise full reverse construction method which comprises the following steps: S1, constructing a supporting waterproof curtain structure along the periphery of a foundation pit, and arranging a middle steel pipe upright post in the foundation pit; s2, excavating a first layer of earthwork underground, and then constructing a first layer of structure; s3, excavating underground second-layer earthwork, and then constructing a negative first-layer structure; s4, according to the step S3, earthwork from the third underground layer to the N-2 underground layer is excavated in sequence, and structures from the second negative layer to the N-3 negative layer are constructed; s5, excavating underground (N-1) layers of earthwork, and reserving a halfpace with a certain width along the support edge; s6, consequent construction is conducted from a podium building soil taking opening bottom plate to a podium building overground structure, and reverse construction is conducted on a minus N-1 layer structure; s7, reserved halfpace remaining soil underground excavation is conducted on the negative N-1 layer structure, and a negative N layer bottom plate structure is constructed; and S8, sequential construction is conducted on a basement soil taking opening structure and a basement post-construction vertical structure. The method is convenient to construct and efficient in work, saves manpower and material resources, accelerates the construction progress and shortens the construction period.
本发明涉及一种超高层全逆作施工方法，包括以下步骤：S1、沿基坑周边施工支护止水帷幕结构，在基坑内设置中间钢管立柱；S2、开挖地下一层土方，再施工首层结构；S3、开挖地下二层土方，再施工负一层结构；S4、按照步骤S3依次开挖地下三层至地下N‑2层土方以及施工负二层至负N‑3层结构；S5、开挖地下N‑1层土方，沿支护边预留一定宽度的梯台；S6、裙楼取土口底板至裙楼地上结构顺作施工，负N‑1层结构逆作施工；S7、负N‑1层结构进行预留梯台余土暗挖，施工负N层底板结构；S8、地下室取土口结构及地下室后做竖向结构进行顺作施工。该方法施工方便、工作高效、节省人力物力，加快施工进度，缩短工期。
