Supporting structure capable of automatically regulating and controlling deformation and implementation method thereof
The invention relates to a supporting structure capable of automatically regulating and controlling deformation and an implementation method thereof. The supporting structure comprises a concrete support, a groove type concrete enclosing purlin and hydraulic jacks, wherein the inner side of the groove type concrete enclosing purlin is in rigid connection with the concrete support, the outer side of the groove type concrete enclosing purlin faces a foundation pit enclosure wall, a plurality of grooves are formed in the outer side of the groove type concrete enclosing purlin in the circumferential direction, the hydraulic jacks are arranged in the grooves, and the two ends of the hydraulic jacks abut against the foundation pit enclosure wall and the groove type concrete enclosing purlin respectively. Compared with the prior art, the supporting structure has the advantages that the axial force of the concrete support can be dynamically regulated and controlled according to deformation monitoring during foundation pit construction, reliable counter force can be actively provided for the enclosure wall to control deformation, horizontal deformation generated by creep shrinkage, temperature shrinkage and the like of concrete can be compensated, and disturbance to the surrounding environment of a foundation pit can be reduced.
本发明涉及一种自动调控变形的支撑结构及其实施方法，支撑结构包括混凝土支撑、凹槽式混凝土围檩和液压千斤顶，凹槽式混凝土围檩的内侧与混凝土支撑刚性连接，凹槽式混凝土围檩的外侧朝向基坑围护墙，且凹槽式混凝土围檩的外侧沿周向方向设有多个凹槽，液压千斤顶设置于凹槽内，两端分别抵在基坑围护墙和凹槽式混凝土围檩上。与现有技术相比，本发明可以在基坑施工期间根据变形监测动态调控混凝土支撑的轴力，能主动对围护墙提供可靠的反力控制变形，又能补偿混凝土徐变收缩、温度收缩等产生的水平变形，有利于减少对基坑周边环境的扰动。
