Construction method of detachable steel pipes for basement back-jacking
The invention discloses a construction method of detachable steel pipes for basement back-jacking. The construction method of the detachable steel pipes for basement back-jacking is characterized by comprising the following steps that a, a formwork is laid below a basement top plate according to design; b, the multiple detachable steel pipes are arranged; c, the detachable steel pipes are arranged at the positions, where stress is large, of the basement top plate, and another detachable steel pipe needs to be arranged between the detachable steel pipes when the distance between every two adjacent detachable steel pipes is larger than 4 m; and d, concrete is poured after all the detachable steel pipes are installed in place, and a complete stress system is formed after the detachable steel pipes are fixed. The construction method of the detachable steel pipes for basement back-jacking has the advantages that the detachable steel pipes are simple in structure and convenient to manufacture, the supporting engineering quality is safe and reliable, a supporting system is simple, the safety coefficient is high, the detachable steel pipes are easy to erect and disassemble, supporting steel pipes can be repeatedly used, the working efficiency is improved, and the construction cost is reduced.
一种地下室回顶可拆卸钢管施工方法，其特征在于包括以下步骤：a、根据设计在地下室顶板下方铺设模板，b、设置若干可拆卸钢管，c、可拆卸钢管设置在地下室顶板受力较大的位置，相邻两根可拆卸钢管间距大于4m时，中间需再设置一根可拆卸钢管，d、可拆卸钢管需全部安装到位后浇筑混凝土，可拆卸钢管固定后形成完整的受力体系。本发明的地下室回顶可拆卸钢管施工方法具有可拆卸钢管结构简单、制作方便，支撑工程质量安全可靠，支撑体系简单、安全系数高、可拆卸钢管支设、拆卸操作简单，支撑钢管可重复使用，提高工作效率和降低施工成本的优点。
