Deep and large foundation pit construction technology based on reverse construction method lattice type tower crane foundation
The invention discloses a deep and large foundation pit construction process based on a reverse construction method lattice type tower crane foundation, which is characterized by comprising the following steps: step 1, measuring and positioning; 2, construction of cast-in-place piles; step 3, hoisting construction; 4, checking and fixing the position; fifthly, pile body concrete pouring is conducted; sixthly, backfilling and pouring are conducted; seventhly, welding, binding and formwork construction are conducted; 8, embedded part installation and lightning protection welding are carried out; ninthly, concrete pouring and watering maintenance are conducted on the bearing platform; and tenthly, the tower crane is installed and detected. A tower crane is arranged at the top of a foundation pit by adopting a reverse construction method lattice tower crane foundation construction technology, so that the tower crane is quickly put into use in time, the difficulty in hoisting materials and equipment in the construction process of the deep and large foundation pit can be effectively solved, and favorable conditions are created for project development; and effective integration is realized to form a whole.
本发明公开了一种基于逆作法格构式塔吊基础的深大基坑施工工艺，其特征在于：包括有，分为以下步骤：步骤一，测量定位；步骤二，灌注桩施工；步骤三，吊装施工；步骤四，位置校核并固定；步骤五，桩身混凝土浇筑；步骤六，回填浇筑；步骤七，焊接绑扎与模板施工；步骤八，预埋件安装与防雷焊接；步骤九，承台砼浇筑与浇水养护；步骤十，塔吊安装与检测。本发明通过采用逆作法格构式塔吊基础施工技术将塔吊布置在基坑顶部，使之快速及时投入使用，可有效解决深大基坑施工过程中材料设备吊装难题，为项目开展创造有利条件，底部灌注桩与顶部承台中间通过格构柱连接，有效整合并形成整体。
