Concrete axial force servo supporting system capable of actively controlling deformation
The invention belongs to the field of building foundation pit supporting, and relates to a concrete axial force servo supporting system capable of actively controlling deformation. According to the technical scheme, a first side edge enclosure body of a peripheral enclosure body, a longitudinal reinforced concrete support of a reinforced concrete support and a first reinforced concrete purlin edge of a reinforced concrete purlin are located on the side with the high environmental protection requirement; a loading end is arranged on one side of the longitudinal bar concrete support, and a first structural joint is arranged between the loading end and the first reinforced concrete purlin edge, so that the loading end becomes a cantilever span; the loading end is provided with a groove; a hydraulic jack is arranged in the groove, and according to the deformation control requirement of the foundation pit, axial force towards the outside of the pit is applied to the first reinforced concrete purlin edge at the end of the longitudinal reinforced concrete support in real time; and a second structural joint is arranged between the first reinforced concrete purlin edge and the second reinforced concrete enclosing purlin intersecting with the first reinforced concrete purlin edge. According to the technology, a reinforced concrete supporting system and an axial force servo system are effectively fused, the advantages of the reinforced concrete supporting system and the axial force servo system are exerted at the same time, the problem of foundation pit excavation deformation in a high-environment-protection area is simply, conveniently and effectively solved, and therefore the purposes of reducing soil disturbance, expanding the application range, effectively controlling deformation, achieving low carbon and saving energy are achieved.
本发明属于建筑基坑支护领域的一种可主动控制变形的混凝土轴力伺服支撑系统，技术方案为：周边围护体的第一侧边围护体、钢筋混凝土支撑的纵向钢筋混凝土支撑和钢筋混凝土围檩的第一钢筋混凝土檩边为位于环境保护要求高一侧；纵向筋混凝土支撑的一侧设置加载端，加载端与第一钢筋混凝土檩边之间设置第一构造缝，使加载端成为悬臂跨；加载端设有凹槽；凹槽内设置液压千斤顶，根据基坑的变形控制需要，在纵向筋混凝土支撑的端部对第一钢筋混凝土檩边实时施加往坑外方向的轴力；第一钢筋混凝土檩边与其相交的第二钢筋混凝土围檩之间设置第二构造缝。该技术有效地将钢筋混凝土支撑体系和轴力伺服系统融合，同时发挥二者的优势，简便且有效地解决了高环境保护区的基坑开挖变形问题，从而达到减少土体扰动、扩大适用范围、有效控制变形和低碳节能的目的。
