Deep foundation pit prestressed profile steel inner support and construction method
The invention relates to a deep foundation pit prestressed profile steel inner support and a construction method. A foundation pit profile steel support gap concrete pouring rapid formwork erecting system is adopted. A foundation pit profile steel stand column is adopted for shaping a guide support; a horizontal steel supporting system provided with an unearthed steel platform is adopted; inserting and driving of inner side steel sheet piles and outer side steel sheet piles are included; the steel enclosing purlins are used as side formworks, a foundation pit profile steel supporting gap concrete pouring rapid formwork erecting system is formed, and gap concrete is poured; and the shaped guide bracket is used for arranging the steel stand column by utilizing the guide groove. The method has the beneficial effects that by optimizing the deep foundation pit prestressed profile steel inner support system, the application range of the prestressed profile steel inner support is further popularized, efficient and safe construction is achieved, the method is applied to actual engineering, the cost can be effectively reduced, and good technical and economic benefits are obtained.
本发明涉及一种深基坑预应力型钢内支撑及施工方法，采用基坑型钢支撑间隙混凝土灌注快速支模体系；采用基坑型钢立柱定型化导向支架；采用设置出土钢平台的水平型钢支撑体系；包括内侧钢板桩和外侧钢板桩插打；以钢围檩为侧模，形成基坑型钢支撑间隙混凝土灌注快速支模体系，浇注间隙混凝土；定型化导向支架利用导向槽施打钢立柱。本发明的有益效果是：通过优化深基坑预应力型钢内支撑体系，将预应力型钢内支撑的应用范围进一步推广，实现了高效、安全施工，应用于实际工程可有效降低成本，取得较好的技术经济效益。
