Foundation pit safety construction control method
The invention discloses a foundation pit safety construction control method, one side of a foundation pit is close to an existing railway line, and the method comprises the steps that settlement monitoring and displacement monitoring are carried out on an enclosure structure of the foundation pit and the existing railway line, and graded early warning is carried out according to settlement and displacement deformation values and deformation rates of all monitoring points; and axial force and temperature monitoring is conducted on all the steel supports horizontally arranged in the foundation pit, and all the steel supports are heated or cooled according to the axial force or temperature changes of all the steel supports. The deformation development trend of the foundation pit, the existing railway and the surrounding environment in the construction process can be found in time, potential safety hazards existing in construction can be found as soon as possible, and foundation pit construction safety and structural stability are ensured.
本发明公开了一种基坑安全施工控制方法，所述基坑的一侧靠近既有铁路线路，包括：对基坑的围护结构和既有铁路线路进行沉降监测和位移监测，并根据各监测点的沉降和位移变形值和变形速率进行分级预警；对基坑内水平设置的各钢支撑进行轴力及温度监测，并根据各钢支撑的轴力或温度变化对各钢支撑进行加热或降温。本发明能够及时发现施工过程中基坑、既有铁路和周边环境变形发展趋势，及早发现施工存在的安全隐患，确保基坑施工安全及结构的稳定性。
