Steel and concrete combined type inner supporting structure for foundation pit
The invention discloses a steel-concrete combined inner support structure for a foundation pit, which is characterized in that an axial force compensation device is used for applying pre-stressing force to a profile steel support along the axial direction of the profile steel support, so that the rigidity of a steel support is the same as that of a concrete support; earth excavation and vertical conveying of materials are facilitated, the construction efficiency is improved, and low carbon and environmental protection are achieved. In addition, the steel supports are connected and assembled together through bolts and can be recycled, and the engineering construction cost is reduced. The combined type inner support solves the problem that a concrete support and a steel support of a traditional combined type inner support of the foundation pit do not coincide on the plane position, so that foundation pit excavation and material conveying are inconvenient.
本发明公开了一种用于基坑的钢混组合型内支撑结构，通过轴力补偿装置对型钢支撑施加沿其轴向的预加力，使得钢支撑达到混凝土支撑相同的刚度，另一方面，由于混凝土支撑和钢支撑在平面位置上上下重合，既方便土方开挖和物料垂直运送，又提高了施工效率、低碳环保。此外，钢支撑通过螺栓连接组装在一起，可以回收利用，降低了工程施工成本。本发明解决了传统的基坑的组合型内支撑的混凝土支撑和钢支撑在平面位置上不重合导致基坑开挖和物料运送不方便的问题。
