Soft soil foundation pit excavation method
The invention belongs to the technical field of foundation pit excavation, and particularly relates to a soft soil foundation pit excavation method. A steel support servo system used in the method involves an installing plate, a partition plate is fixed to the top end of the installing plate, a hydraulic station is fixed to the top end of the installing plate, a hydraulic cylinder is fixed to theside wall of the partition plate, the hydraulic station communicates with the hydraulic cylinder through an oil pipe, a push plate is fixed to the output shaft end of the hydraulic cylinder, a temperature sensor is arranged on the push plate, a baffle is fixed to the top end of the installing plate, protection plates are fixed to the top ends of the baffle and the partition plate, and an installing flange is fixed to the side, away from the hydraulic station, of the baffle. According to the soft soil foundation pit excavation method, the steel support servo system is monitored and adjusted intime through arrangement of the temperature sensor and a push rod motor, so that a gap and pressure between the steel support servo system and the section of a foundation pit are kept stable, then thesteel support effect is improved, and smooth excavation of the foundation pit is guaranteed.
本发明属于基坑开挖技术领域，具体的说是一种软土基坑开挖方法，本方法中使用的钢支撑伺服系统包括安装板，所述安装板顶端固定有分隔板，所述安装板顶端固定有液压站，所述分隔板侧壁上固定有液压缸，所述液压站通过油管与液压缸连通，所述液压缸的输出轴端固定有推板，所述推板上设有温度传感器，所述安装板顶端固定有挡板，所述挡板和分隔板顶端固定有防护板，所述挡板远离液压站的一侧固定有安装法兰；本发明通过温度传感器以及推杆电机的设置来及时对钢支撑伺服系统进行监控和调整，使得钢支撑伺服系统与基坑断面之间的间隙以及压力保持稳定，从而提高了钢支撑的效果，进而保证了基坑的顺利开挖。
