Construction method of cover-excavation deep foundation pit supporting system
The invention relates to a construction method of a cover excavation deep foundation pit supporting system. The construction method comprises the steps of fender post and steel stand column construction, foundation pit excavation and supporting construction, cover plate construction, excavation construction, bottom plate construction and cover plate dismantling. The construction method has the beneficial effects that the fender post hanging net sprayed concrete supporting structure and the fender post and steel enclosing purlin rapid connecting system are adopted, operation is easy, local materials can be used, and the strength of the supporting structure and the field construction efficiency are improved; construction is conducted through the steel stand column accurate insertion auxiliary device, the insertion accuracy of the steel stand column is guaranteed, the complexity of manual adjustment in a traditional method is reduced, manpower is saved, and the construction efficiency is improved; the steel stand column supporting type reinforced concrete cover plate formwork supporting system and the reinforced concrete cover plate steel stand column are adopted for construction, the stability of the formwork supporting structure is improved, meanwhile, reinforcement can be conducted according to special conditions, and smooth proceeding of the construction process and safety of lower personnel are guaranteed.
本发明涉及一种盖挖深基坑支护体系的施工方法，包括步骤：围护桩和钢立柱施工、基坑开挖和支护施工、盖板施工、开挖施工、底板施工、盖板拆除。本发明的有益效果是：采用围护桩挂网喷射混凝土支护结构和围护桩与钢围檩快速连接体系，操作简单，可就地取材，提高了支护结构强度和现场施工效率；通过钢立柱精确插设辅助装置进行施工，保证了钢立柱插设的精度，减少了传统方法中人工调节的繁琐，节约了人力，提高了施工效率；采用钢立柱支撑式钢筋混凝土盖板支模体系和钢筋混凝土盖板钢立柱设置牛腿托架补强结构进行施工，提高了支模结构的稳定性，同时针对特殊情况可进行加固补强，保证了施工过程的顺利进行以及下部人员的安全。
