Electric power foundation pit construction environment monitoring device and monitoring method

Abstract

The invention relates to the technical field of electric power foundation pit monitoring, in particular to an electric power foundation pit construction environment monitoring device and method. Comprising a detection rod and a pipe orifice fixing unit, the pipe orifice fixing unit comprises a pipe orifice lantern ring; a second rotating ring is rotationally connected to the outer part of the pipe orifice lantern ring in a sleeving manner; a lantern ring inner cavity is formed in the pipe opening lantern ring, and a plurality of sets of bottom sliding grooves are distributed in the inner wall of the bottom of the lantern ring inner cavity in an annular array mode. The two ends of the bottom sliding groove extend towards the inner walls of the two sides of the inner cavity of the lantern ring correspondingly. An inclinometer limiting mechanism is slidably connected into the bottom sliding groove, an upper lantern ring is installed at one end of the pipe opening lantern ring, the central axis of the pipe opening lantern ring coincides with the central axis of the upper lantern ring, and the detection rod is movably sleeved with the pipe opening lantern ring and the upper lantern ring; and a cable pushing unit is movably clamped on the inner wall of the upper lantern ring. According to the invention, the fixing effect can be realized on the inclinometer pipe of any size, and the compatibility is improved.

Description

technical field [0001] The invention belongs to the technical field of power foundation pit monitoring, and particularly relates to a power foundation pit construction environment monitoring device and a monitoring method. Background technique [0002] When laying cables, it is necessary to dig a power foundation pit on the ground first, and in order to ensure the normal progress of the cable laying work, it is necessary to monitor the construction environment in the power foundation pit. [0003] There are many monitoring items for the construction environment in the power foundation pit, among which the horizontal displacement of the soil in the power foundation pit is particularly important. Because the horizontal displacement of the soil can directly reflect the influence of the power foundation pit on the surrounding buildings. [0004] When monitoring the horizontal displacement of the power foundation pit, it is first necessary to bury the inclinometer pipe verticall...

Problems solved by technology

[0005] When the traditional inclinometer is in use, the staff needs to manually insert it into the inclinometer tube. Due to manual differences, it is difficult for the central axis of the probe rod to always coincide with the central axis of the inclinometer tube, which causes the probe rod to be in the measuring clamp. The accuracy decreases when the angle
