Ultra-long distributed shrinkage compensation concrete supporting structure and construction method
The invention relates to the field of civil engineering, in particular to an ultra-long distributed shrinkage compensation concrete supporting structure which comprises an enclosing purlin arranged in a foundation pit, transverse diagonal bracings and longitudinal diagonal bracings are installed in the enclosing purlin, and a bearing assembly used for bearing the transverse diagonal bracings and the longitudinal diagonal bracings is arranged in the foundation pit. A plurality of adjusting seams used for shrinkage compensation are formed in the transverse diagonal braces in the length direction of the transverse diagonal braces, the transverse diagonal braces are divided into a plurality of branch braces through the adjusting seams, and an axial loading assembly used for adjusting the axial loading force of the branch braces is arranged between every two adjacent branch braces. Active control over the sectional deformation of the super-long concrete support is achieved, the problems that the supporting axial force cannot be fully exerted due to concrete shrinkage and the lateral deformation of the stand column is large are solved, it is guaranteed that the whole transverse supporting foundation pit is not prone to large deformation in the construction process, and the safety of constructors is guaranteed.
本申请涉及土建领域，尤其是涉及一种超长分布式收缩补偿混凝土支撑结构，包括设置在基坑内的围檩，所述围檩内安装有横向对撑和纵向对撑，所述基坑内设置有用于承托横向对撑和纵向对撑的承托组件，所述横向对撑沿自身长度方向开设有若干个用于收缩补偿的调节缝，所述调节缝将所述横向对撑分割成若干个分撑，相邻两个分撑之间设置有用于调节分撑轴向加载力的轴向加载组件，通过上述方案，实现超长混凝土支撑分段变形主动控制，解决了混凝土收缩导致支撑轴力无法充分发挥、立柱侧向变形较大的难题，保证了整个横向支撑基坑在施工过程中难以发生较大的变形，保障了施工人员的安全。
