Pile foundation, latticed column and steel structure bearing platform comprehensive tower crane foundation construction technology
The invention belongs to the technical field of engineering, and particularly relates to a pile foundation, latticed column and steel structure bearing platform comprehensive tower crane foundation construction technology which comprises the following steps: (1) accurately positioning a cast-in-situ bored pile foundation according to a set tower crane position, arranging different measurers to repeatedly check tower crane foundation positioning points, and ensuring that the tower crane foundation is positioned accurately in a paying-off manner; and (2) drilling construction: embedding a pile casing, drilling in a layered manner in hole-forming construction, and changing slurry to clean the hole. The problem that the tower crane needs to be put into use in advance during deep foundation pit construction of a construction project is solved, and the method has important significance on basement and foundation pit support construction. And the performance and the bearing capacity of the tower crane are met, and the construction requirements of simple structure and simple and convenient construction are met. Meanwhile, the problems that traditional tower crane foundation construction is limited by large-area earth excavation, the construction period is long, and the working procedures are tedious are solved.
本发明属于工程技术领域，尤其涉及一种桩基础、格构柱、钢结构承台综合塔吊基础施工技术，包括以下步骤：（1）根据既定塔吊位置进行钻孔灌注桩桩基精确定位，安排不同测量员重复复核塔吊基础定位点，确保塔吊基础放线定位准确；（2）钻孔施工，埋设护筒，成孔施工分层钻进，换浆清孔。本发明解决了建设工程深基坑施工，要想实现塔吊提前投入使用的问题，对地下室和基坑围护施工有重要意义。满足塔吊本身的性能及承载能力，以及结构简洁、施工简便的施工需求。同时，处理了传统塔吊基础施工受制于大面积土方开挖、工期长、工序繁琐的难题。
