Description
Technical Field
[0001] This utility model relates to the field of construction monitoring and management technology, and more specifically to a collaborative control platform for deformation during open-cut foundation pit construction around subway stations. Background Technology
[0002] Underground projects such as underground rail transit, underground parking garages, underground substations, underground shopping malls, underground civil defense projects, and multi-story basements of high-rise buildings are increasing, resulting in a large number of deep and large foundation pit projects.
[0003] The open-cut method refers to an underground construction method where the ground is first excavated, the lining is constructed in the open, and then backfilled. It is inexpensive, reliable, and safe, ensuring the quality of the main structure. However, it has a significant impact on the surrounding environment and traffic. Subway perimeter foundation pit deformation monitoring projects are characterized by a large number of monitoring points and high monitoring frequency. Traditional subway foundation pit monitoring often relies on manual methods, which are inefficient and often lack accuracy. Furthermore, the manual on-site recording of monitoring data followed by computer entry is prone to errors and lacks real-time data updates, failing to promptly reflect deformation at each monitoring point and issue alarms for problematic locations, resulting in a lag in monitoring efforts.
[0004] Therefore, how to monitor the open-cut foundation pit and the surrounding subway situation in real time is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] In view of this, the present invention provides a collaborative control platform for deformation during open-cut foundation pit construction around a subway, which can realize real-time monitoring of the open-cut foundation pit and the surrounding subway conditions.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

The information acquisition unit collects data on the foundation pit, the subway, and the surrounding environment, and transmits this data to the processing unit via the central control unit. The processing unit has preset alarm thresholds for corresponding data. When the corresponding data in the information acquisition unit exceeds the alarm threshold, the central control unit sends the corresponding data and an alarm signal to the alarm unit. The alarm unit issues alarms at corresponding frequencies based on the alarm signals. The alarm unit is connected to the display unit, which displays the data corresponding to the alarm signals. The power supply unit provides energy to the information acquisition unit, central control unit, display unit, processing unit, and alarm unit.

[0011] Preferably, the subway monitoring subunit includes a static level and an automatic total station. The automatic total station is fixed in the subway tunnel near the foundation pit to monitor the coordinate data of each preset monitoring point. The static level is fixed on the side of the expansion tube water trough, which is drilled and buried on the side of the track bed water trough, to obtain vertical displacement data.
[0012] Preferably, the foundation pit monitoring subunit includes a deformation monitoring module, an inclination sensor, and a pore water pressure sensor. The deformation monitoring module includes several MEMS sensors, which are connected by flexible connectors via wiring and arranged in an array on the sidewall of the open-cut foundation pit to acquire foundation pit deformation data.

It integrates multiple sensors, including a deformation monitoring module (including MEMS sensors) for monitoring the foundation pit, tilt sensors, pore water pressure sensors, and temperature sensors; a hydrostatic level and automatic total station for monitoring the subway; and surface settlement monitoring sensors, water level monitoring sensors, and building settlement monitoring sensors for monitoring the surrounding environment. These sensors can monitor the foundation pit, subway, and surrounding environment in real time from multiple angles, acquiring comprehensive data. Automated real-time early warning is achieved through preset alarm thresholds, avoiding omissions and delays that may occur with manual monitoring. It covers the monitoring of the foundation pit, subway, and surrounding environment, enabling a comprehensive understanding of various situations during the construction process. Whether it's the stability of the foundation pit itself, the safety of the subway structure, or the impact of the surrounding environment, all can be effectively monitored and evaluated.
