Deep and large foundation pit concrete support servo system and construction method
The invention provides a deep and large foundation pit concrete support servo system and a construction method.The deep and large foundation pit concrete support servo system adopts a foundation pit analysis platform, a plurality of wireless monitoring sensors and a plurality of concrete support servo systems, and each concrete support servo system comprises a concrete support, a plurality of hydraulic jacks and a hydraulic servo control system; a groove is formed in the position, corresponding to a concrete support, of the side, away from an enclosure structure, of an enclosing purlin, an isolation steel plate is laid on the bottom face of the groove, a sliding layer is laid on the isolation steel plate, one end of the concrete support extends into the groove and is located on the sliding layer, and the concrete support can slide relative to the isolation steel plate by arranging the sliding layer; therefore, active control over the concrete supporting axial force of the deep and large foundation pit is achieved. The support box is arranged on the sliding layer of the corresponding groove, and the hydraulic jack is arranged in the support box, so that the concrete support can transmit the reactive force of the concrete support to the enclosure structure through the enclosing purlin, and the enclosing purlin can be prevented from being separated from the enclosure structure.
本发明提供一种深大基坑混凝土支撑伺服体系及施工方法，采用基坑分析平台、若干无线监测传感器以及若干道混凝土支撑伺服系统，每道混凝土支撑伺服系统包括混凝土支撑、若干液压千斤顶以及液压伺服控制系统，通过在围檩上远离围护结构的一侧对应混凝土支撑处设置凹槽，凹槽的底面上铺设一隔离钢板，在隔离钢板上方铺设滑移层，混凝土支撑的一端伸入凹槽内并位于滑移层上，通过设置滑移层使得混凝土支撑能够相对隔离钢板滑移，从而实现深大基坑混凝土支撑轴力的主动控制；通过将支座箱设置于对应的凹槽的滑移层上，支座箱内设置液压千斤顶，使得该混凝土支撑能够将自身的反作用力经围檩传递给围护结构，可以防止围檩与围护结构分离。
