Concrete support remaining joint structure for deep foundation pit engineering and construction method of concrete support remaining joint structure
The invention relates to the technical field of deep foundation pit engineering design and construction, in particular to a concrete support reserved joint structure for deep foundation pit engineering and a construction method of the concrete support reserved joint structure for the deep foundation pit engineering. A U-shaped embedded steel plate is embedded in the end of a concrete waist beam, and the concrete waist beam is connected with an underground diaphragm wall through a connecting steel bar penetrating through the U-shaped embedded steel plate; the steel bars of the lining walls located on the upper side and the lower side of the concrete waist beam are communicated and continuous through the U-shaped embedded steel plates. The method has the advantages that the design of a concrete support reserving technology is realized, construction inconvenience and increase of engineering cost caused by replacement of the concrete support can be effectively avoided, the construction efficiency is improved, and the engineering cost of replacement of the concrete support is saved.
本发明涉及深基坑工程设计及施工技术领域，尤其是一种用于深基坑工程的混凝土支撑留撑接头结构及其施工方法，在所述砼腰梁的端部预埋有U型预埋钢板，所述砼腰梁与所述地下连续墙之间通过穿过所述U型预埋钢板的连接钢筋连接；位于所述砼腰梁上、下两侧的所述内衬墙的钢筋通过所述U型预埋钢板构成贯通连续。本发明的优点是：实现混凝土支撑留撑技术的设计，可以有效避免混凝土支撑换撑带来的施工不便及工程造价的增加，提高施工效率和节省混凝土支撑换撑的工程费用。
