Description

An adjustable deep foundation pit depth measuring device

Technical Field

The utility model relates to the technical field of foundation pit depth measurement, in particular to an adjustable deep foundation pit depth measuring device.

Background technique

Deep foundation pit refers to the project with excavation depth exceeding five meters (including five meters), or the project with depth not exceeding five meters but with complicated geological conditions, surrounding environment and underground pipelines. During the excavation of deep foundation pit, over-excavation or under-excavation is often prone to occur. Among them, over-excavation of foundation pit is prone to cause excessive deformation and cracking of foundation pit, and even lead to damage of supporting structure or landslide of soil, and finally collapse of foundation pit. Therefore, depth measurement of deep foundation pit is particularly important.

The invention patent application with application publication number CN111622744A discloses a depth detection device for a vertical shaft foundation pit. The depth detection device is connected to a servo motor at one end of a fixed frame. The servo motor starts to drive the coil to rotate, and the traction rope is wound or loosened. The traction rope changes the direction of force under the action of a fixed pulley, and drives the weight block to penetrate into the interior of the vertical shaft to test the depth of the vertical shaft. However, the depth detection device is only fixed to the periphery of the foundation pit by fixing bolts, and the position of the weight block cannot be adjusted. When the equipment base cannot be fixed around the foundation pit, or the measuring device is still a certain distance away from the foundation pit after the equipment base is fixed, the depth detection device cannot measure the foundation pit.
