Construction method of inverted stepped radial tower crane concrete foundation
The invention provides a construction method of an inverted stepped radial tower crane concrete foundation. The construction method comprises the following steps: optimizing a tower crane foundation; optimizing a post-cast strip around the tower crane foundation; the tower crane foundation, the enlarged foundation and the bottom plate are subjected to synchronous steel bar construction, and tower crane pre-embedding and lightning protection grounding construction are carried out during construction; foundation and bottom plate concrete pouring construction is conducted, and the precision of the embedded parts is monitored in the period; mounting a tower crane; and monitoring and testing the tower crane. The influence of the natural foundation bearing capacity on the tower crane foundation can be effectively reduced, engineering piles of a bearing platform on the periphery of the originally designed tower crane foundation are included in the mode that the foundation is expanded in a radioactive mode on the originally designed tower crane foundation in the specification, and the construction engineering amount and the construction period of the tower crane piles are saved; and meanwhile, the plate thickness and reinforcement of the expanded foundation are optimized according to the safety calculation result, and the economic effect of saving the overall foundation project amount on the premise of meeting the safety requirement is achieved. On the premise that the safety of the tower crane foundation is guaranteed, the construction period is shortened, and the construction cost is saved.
本发明提供一种倒置阶梯式放射型塔吊砼基础施工方法，包括：塔吊基础优化；塔吊基础周边后浇带优化；塔吊基础、扩大基础与底板同步钢筋施工，期间进行塔吊预埋及防雷接地施工；基础及底板混凝土浇筑施工，期间对预埋件精度进行监测；安装塔吊；塔吊监测测试。本发明可以有效降低自然地基承载力对塔吊基础的影响，通过在说明书原设计塔吊基础上放射性扩大基础的方式，囊括原定塔吊基础周边承台的工程桩，节约塔吊桩的施工工程量及工期；同时根据安全计算结果优化扩大基础的板厚及配筋，达到在满足安全要求的前提下，节约整体基础工程量的经济效果。本发明可以在保证塔吊基础安全性的前提下，缩短工期，节约施工成本。
