Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit support monitoring equipment, in particular to a deep and large foundation pit support monitoring device. Background Art

[0002] In order to ensure the working safety of the support equipment in deep and large foundation pits, it is often necessary to monitor the support equipment, and thus it is necessary to use foundation pit support monitoring equipment. The utility model patent with patent application number CN202320165096.1 discloses a foundation pit support monitoring device, which drives the vertical plate to slide relative to the base plate by pushing the connecting block to slide through the horizontal push cylinder. The main push cylinder pushes the vertical plate to flip around the slider to adjust the inclination angle of the vertical plate. The output shaft of the vertical push cylinder pushes the shell downward and inserts it into the soil to improve the bonding strength between the base plate and the soil. After the shell is inserted into the soil, the sliding part is driven by adjusting the output shaft of the oil cylinder to push the oil cylinder to move relative to the vertical position, and the wall surface of the sliding part pushes each embedded The shell slides out and is horizontally embedded in the soil to achieve anchoring of the shell. On the basis of achieving anchoring of the base plate, the bonding strength between the shell and the soil is increased by setting a horizontally sliding embedded part, which can bear greater load and has a better anti-sliding displacement effect. According to the technical solution disclosed by the invention, when the existing foundation pit support monitoring equipment is used, on the one hand, it cannot effectively monitor whether the support is tilted and whether the support equipment moves outward, thereby reducing the working range of the detection equipment. On the other hand, it cannot effectively guarantee the sensitivity of the detection equipment. When the support equipment moves or tilts slightly, it is often not possible to detect it in time, thereby ensuring the accuracy of the monitoring equipment.
