Abstract

The invention discloses a foundation pit deep layer horizontal displacement measuring device for controlling a probe to move at equal distance, and belongs to the technical field of foundation pit engineering. The foundation pit deep layer horizontal displacement measuring device comprises the probe, measuring and reading equipment, a cable for connecting the probe and the measuring and reading equipment, and further comprises traction equipment for pulling the cable, and the traction equipment can control the probe to move in the axial direction of an inclinometer pipe; and the traction equipment comprises a rack, a winding wheel, a first stepping motor, a guide wheel set and a vertical movement control assembly, the cable is wound on the winding wheel, the winding wheel is in transmission connection with the first stepping motor, the first stepping motor releases the cable at equal distance according to a rule, and the vertical movement control assembly controls the winding wheel to move up and down along the rack. The foundation pit deep layer horizontal displacement measuring device can be used for controlling the probe to move in the inclinometer pipe at equal distance, the problem of high strength caused by manual measurement is solved, the operation instability caused by manual measurement is further avoided, and the measurement result is more accurate.

Description

technical field [0001] The invention belongs to the technical field of foundation pit engineering, and in particular relates to a deep horizontal displacement measuring device for controlling the equidistant movement of probes. Background technique [0002] The deep horizontal displacement parameter is a mandatory item required by the foundation pit monitoring specification, and it occupies most of the working hours in the daily foundation pit monitoring field work. The accurate measurement of deep horizontal displacement can reflect the displacement of soil layers caused by excavation of foundation pit, loading and unloading of soil layers, etc., and can be used to evaluate the degree of impact of engineering construction on the surrounding environment. The conventional method for measuring the deep horizontal displacement is to bury the inclinometer tube in the enclosure structure or the soil layer, and the inclinometer tube coordinates with the structure or soil layer to ...
