Product details

1.Foundation pit monitoring background

Foundation pit monitoring Observe and analyze the soil and soil properties of foundation pit, the displacement of supporting structure and the change of surrounding environmental conditions.Urban foundation pit excavation has the characteristics of high construction risk and great construction difficulty. At present, the excavation of foundation pits in Shenzhen, Guangzhou, Dongguan and other places is getting deeper and deeper, from the initial four to eight meters to the current deepest of more than 20 meters. Due to the complexity of underground soil properties, load conditions, and construction environment, the design and construction plan determined solely based on geological survey data and indoor geotechnical test parameters often contains many uncertain factors. Monitoring of changes in soil properties, environment, adjacent buildings, and underground facilities caused during the construction process has become an indispensable and important part of engineering construction. It is also the eyes to guide correct construction, a necessary measure to avoid accidents, and an information technology. At present, foundation pit monitoring is listed as one of the three basic elements of deep foundation pit engineering quality assurance along with engineering design and construction.

2. Foundation pit monitoring system overview

As a pioneer in China's structural safety monitoring industry, our company has taken the lead in combining structural health monitoring with IoT structural systems, cloud computing, LAN/communication networks and other multi-network seamless connection technologies to establish an intelligent foundation pit online monitoring system to conduct real-time monitoring of foundation pit construction sites. The monitoring system based on the cloud computing service center can accommodate monitoring data of tens of thousands of bridges, tunnels, slopes and other structures, forming a regional structural health monitoring platform to achieve unified monitoring and management of all structures in the region.

3. Main monitoring contents of Foundation pit monitoring

1. Construction foundation pit: settlement and horizontal displacement of the top of retaining piles (walls), deep horizontal displacement of retaining piles (walls), internal force of retaining piles (walls), deep horizontal displacement of soil outside the pit, axial force of anchor rods, groundwater level, axial force of support, and uplift of pit bottom

2. Surrounding risk sources: surface settlement, pipeline settlement, building tilt, uneven building settlement, building cracks, bridge pier tilt, uneven bridge pier settlement

6. Foundation pit monitoring implementation functions

1. 24-hour real-time monitoring: Through real-time online monitoring of support structures, surface settlement, retaining pile inclination, etc., the structural changes of the construction foundation pit can be grasped in real time.

2. Report push: The monitoring results are displayed and published in real time, and monitoring reports are pushed to users regularly.

3. Multiple-level warning: Establish a three-level alarm mechanism. When the detection data is abnormal, the user will be notified by SMS, fax, broadcast, etc. at the first time to realize the comprehensive warning function.

4. Emergency plan processing: directly extract the corresponding processing methods from the expert system, and take measures such as personnel intervention and road blocking in time to eliminate safety hazards in the bud.

5. Structural trend analysis: Structural stability trend analysis can be achieved through monitoring data analysis and safety evaluation during foundation pit construction.

6. Historical data storage: The storage of monitoring data provides an analogy basis for the design and construction of similar projects in the future.
