Underground pipe gallery deformation monitoring system

Abstract

The invention provides an underground pipe gallery deformation monitoring system, which comprises a base, a filling block, turning handles, resistors, resistor springs, turning handle springs, base springs and a circuit chip. The base is mounted in the included angle of pipe gallery walls; the filling block is filled in a cut cube block cavity of the base; each resistor installation cavity and a filling block resistor cavity of the base and the filling block form a cylindrical cavity; the inner side of each cylindrical cavity is equipped with one resistor; and the opening of each cylindrical cavity is in a throat shape, and is embedded by a spherical block of the turning handle. When a horizontal wall, a first vertical wall and a second vertical wall are in relative rotation, the walls drive driving slices at the outer ends of the turning handles to move; the inner end of each turning handle rotates, and an eccentric plate at the innermost end of each turning handle presses or releasesa pole plate at the outer side of each resistor, so that the distance between the two pole plates of the resistor changes, length and cross-sectional area of metallic mercury in a soft shell changes,resistance changes, and voltage between the two pole plates of the resistor changes; and by monitoring the change of the voltage value, relative rotated angle of the walls can be calculated.

Description

technical field [0001] The invention relates to a building safety monitoring system, in particular to a deformation monitoring system for an underground comprehensive utility gallery. Background technique [0002] At present, the scale of the comprehensive utility corridors that have been built is still small. As citizens have higher and higher requirements for the urban environment, the potential market size of urban underground comprehensive utility corridors is still large. speed of development. [0003] The underground comprehensive pipe gallery is the lifeline corridor of the city, and it accommodates various types of pipelines. Using modern information technology to manage and monitor the underground comprehensive pipe gallery is an indispensable means. The monitoring of the underground comprehensive pipe gallery includes the monitoring of the safety status of the pipelines in operation, as well as the detection of the internal environment of the underground comprehen...

Problems solved by technology

[0004] However, in addition to settlement, due to long-term temperature and humidity changes and concrete shrinkage, the wall of the pipe gallery will also be deformed such as distortion and cracking. The horizontal deformation of the pipe gallery cannot be monitored only by the static level system. Therefore, It is necessary to design a device system that can monitor the horizontal deformation of the wall of the pipe gallery. After the horizontal deformation of the wall reaches a certain threshold, the staff will repair and maintain the deformed wall in time.
