METHOD FOR ALTERNATELY CONSTRUCTING UNDERGROUND VERTICAL MEMBERS USING TOP-DOWN CONSTRUCTION METHOD
The present invention provides a construction method for shortening a period of underground frame construction in a top-down method, particularly a method for alternately constructing underground vertical members (core parts, pillars) down to lower levels and then constructing the remaining vertical members simultaneously, thus making it possible to shorten the construction period. This construction method comprises: a first step for excavating a first basement level and a floor of a first level of a construction site; a second step for constructing a slab of a basement level downward and constructing a core part of one basement level in order to support a core part of above-ground levels at the same time; a third step for alternately constructing underground vertical members downward; and a step for simultaneously constructing the remaining underground vertical members after constructing a mat of the lowest level or a foundation, wherein the construction period of the underground vertical members is shortened so that subsequent above-ground frame construction and finishing construction can be started early, thus shortening the overall construction period.
本发明提供一种为缩短施工中地下骨架的周期，采用自上而下的反钻法，更具体地，涉及通过提供每隔一个地下垂直构件(核心部，柱子)向下安装，然后将剩余的垂直构件利用同时期施工的施工方法缩短整体施工工期。安装挡土墙和地下柱桩后，包括：开挖地下1层及施工地上一层底板的第一步；向下施工地下层板，同时期先施工地下1层核心部以支撑向上施工的底层核心部的第二步；每隔一个地下垂直构件向下施工的第三步；施工最底层地垫或地基后，同时期安装剩余的地下垂直构件的步骤，通过缩短地下垂直构件，可以提早开始后期的地上构筑和收尾工作，从而缩短整体工期。
