Excavation water level monitoring equipment: real-time control of water level to ensure excavation safety
Date: 2025-12-22Read: 12
WX-DSW4, Shandong Wanxiang Environment, supports multi field environmental monitoring. During the construction process of building foundation pits, the dynamic changes in groundwater level directly affect the stability of the pit. Excessive water level can easily lead to accidents such as slope collapse, piping, and sand flow, seriously threatening construction safety and the safety of surrounding buildings. Traditional foundation pit water level monitoring relies on manual measurement, which has problems such as data lag, large measurement errors, and difficulty in tracking water level changes in real time, making it difficult to meet the dynamic safety control requirements of foundation pit construction. The foundation pit water level monitoring instrument equipment is designed specifically for building foundation pit scenarios, with the core advantages of "precise real-time, easy installation, and strong anti-interference", providing reliable water level monitoring support for the safety of foundation pit construction.
Adaptation to excavation scenarios, convenient and efficient installation. The water level monitoring equipment for the foundation pit adopts a lightweight design, matched with specialized installation accessories, and adopts an input measurement method. 1-2 staff members can quickly complete the installation and deployment without complex construction modifications. In response to the narrow space and complex environment of the foundation pit construction area, the equipment is compact in size and has simple wiring. The sensor probe can be directly inserted into the monitoring well or dewatering well, without affecting the construction processes such as excavation and support of the foundation pit. The equipment is equipped with high-quality air guiding cables that can be soaked in water all year round, with excellent tensile and wear-resistant properties, and can adapt to complex working conditions such as dragging and collision during foundation pit construction; The slope type liquid guide hole design can effectively prevent impurities such as sediment and concrete residue generated during foundation pit construction from entering the probe, avoid blockage, and ensure continuous and stable measurement.
Accurate real-time monitoring to grasp water level dynamics. The equipment is based on the principle of hydrostatic pressure and uses a diffusion silicon piezoresistive sensor to accurately measure changes in groundwater level in foundation pits. The measurement accuracy is high and can capture centimeter level water level fluctuations. The application of core automatic correction algorithm effectively offsets the numerical fluctuations caused by mechanical vibration, water flow disturbance and other factors in foundation pit construction, ensuring the authenticity and stability of monitoring data. The signal transmission adopts RS485 signal output, with a maximum communication distance of up to 2000 meters. It can be directly connected to the monitoring terminal on the construction site, and the management personnel can view the water level data in real time at the construction command center; It can also be uploaded to the IoT platform through a wireless module to achieve remote real-time monitoring, making it convenient for construction and supervision units to synchronously grasp the water level situation of the foundation pit.
Multiple protective measures to adapt to the construction environment. The construction environment of the foundation pit is harsh, and factors such as dust, mud, and mechanical vibration have a significant impact on the operation of the equipment. Multiple protective designs are adopted for the equipment: anti-corrosion stainless steel materials are selected for sensors and protective boxes, which are corrosion-resistant, anti-oxidation, and have a waterproof level of IP66, effectively resisting mud immersion and dust erosion; Equipped with reverse polarity protection and instantaneous overcurrent and overvoltage protection functions, it meets EMI protection requirements and can adapt to complex circuit environments on construction sites, avoiding damage to equipment caused by voltage fluctuations and electromagnetic interference. For outdoor monitoring points, a solar panel top cover embedded power supply module can be used, which has high photoelectric conversion efficiency and strong wind resistance. Paired with an MPPT automatic power point tracking charging controller, the charging efficiency can be increased by 20%, achieving long-term unmanned operation without frequent power replacement.
Intelligent warning empowerment to prevent construction risks. The device supports access to the foundation pit safety monitoring system, and management personnel can customize the water level warning threshold. When the water level in the foundation pit exceeds the safe range (such as approaching the bearing limit of the support structure when the water level is too high, or causing surrounding ground settlement when the water level is too low), the system immediately triggers the warning mechanism, pops up a warning prompt on the monitoring terminal, and sends warning information to designated personnel such as the construction manager and safety supervisor through SMS alarm to ensure that relevant personnel are aware of the risk dynamics. In a high-rise building foundation pit construction project, the equipment monitored the change of water level in real time, found the abnormal rise of water level after a rainstorm and gave an early warning, and the construction team quickly started the emergency drainage system to avoid the risk of foundation pit slope collapse; During the construction of a subway foundation pit, the equipment monitored the water level for a long time and guided the construction team to adjust the dewatering plan reasonably, which not only ensured the safety of the foundation pit but also avoided the surrounding ground settlement caused by excessive dewatering.
