Prestressed reinforced concrete supporting structure control system and method
The invention discloses a prestressed reinforced concrete supporting structure control system and method, and relates to the technical field of foundation pit supporting and construction, the prestressed reinforced concrete supporting structure control system comprises a supporting structure, an external waist beam and an internal waist beam, loading units and supporting blocks are alternately arranged in the same cross section between the external waist beam and the internal waist beam, and the loading units are used for pushing the external waist beam and the internal waist beam to generate horizontal relative displacement, so that prestress is established in advance before lower-layer earthwork is excavated. According to the method, elastic compression deformation of the reinforced concrete support in the foundation pit excavation process can be eliminated, shrinkage deformation, creep and temperature deformation generated by the concrete support can be compensated, deformation, caused by foundation pit excavation, of a supporting structure is actively adjusted, and therefore total settlement of surrounding houses is controlled, and the influence of foundation pit excavation on the surrounding environment is effectively reduced.
本发明公开了一种预应力钢筋混凝土支撑结构控制系统及方法，涉及基坑支护与施工技术领域，包括支护结构、外部腰梁、内部腰梁，所述支护结构侧面支撑标高位置固定有外部腰梁，所述外部腰梁与内部腰梁之间同一横截面内交替布置有加载单元和支撑块，所述加载单元用于推动外部腰梁与内部腰梁产生水平的相对位移，以在未开挖下层土方之前提前建立预应力。本发明能够消除基坑开挖过程中钢筋混凝土支撑的弹性压缩变形，补偿混凝土支撑产生的收缩变形、徐变、温度变形，并主动调整基坑开挖引起支护结构的变形，从而控制周围房屋总沉降，有效减少基坑开挖对周围环境的影响。
