Displacement monitoring device and method for reinforcement and reconstruction engineering

Abstract

The invention discloses a monitoring device and method for reinforcement and reconstruction engineering, the monitoring device comprises a plummet, a trigger and an alarm, and the corresponding positions of a first floor, a first underground floor and a second underground floor of a detected structure are provided with pay-off holes; the line pendant is hung on a roof, sequentially penetrates through pay-off holes of a first floor, a first underground floor and a second underground floor and is perpendicular to a barrel of a third underground floor, the trigger comprises a plurality of conductive wires, every two conductive wires are parallelly arranged at intervals to form a group, the conductive wires are horizontally and crosswise erected at the pay-off holes of the second underground floor, and the conductive wires are connected with the trigger. The plummet penetrates through a center hole defined by the conductive wires, the conductive wires and the plummet are connected with the alarm through wires to form a closed loop, and the alarm is triggered to give an alarm when the plummet touches any conductive wire. The system is simple and reliable in structure, low in cost, small in input of manpower and physical power, accurate in monitoring data, timely in feedback and capable of effectively achieving the inclination, displacement and settlement monitoring function of the building.

Description

technical field [0001] The invention relates to the technical field of building reinforcement and reconstruction projects, in particular to a displacement monitoring device and method for reinforcement and reconstruction projects. Background technique [0002] During the construction of the processing project, part of the existing structure will be demolished and the section will be enlarged, as well as the chiseling and grinding of the existing concrete surface of the part to be reinforced, which may cause the original structure to tilt, settle and move. , Especially for projects located in coastal areas, because the base soil is sandy soil, the construction will disturb the original structure more. Therefore, during the construction process, it is necessary to monitor the state of the original structure in real time and adjust the construction plan in time. [0003] The traditional monitoring methods include using a total station or a plumb bob and a level to monitor the d...

Problems solved by technology

The former needs to invest a lot of manpower and material resources in real-time monitoring and has large errors. Although the latter has a high degree of automation and precision and requires less manpower, the equipment is expensive, and if the project is located overseas, it will face the long-distance transportation of precision instruments There may be damage in the process, and problems such as overseas repair and maintenance difficulties

[0004] This shows that the above-mentioned existing monitoring device and monitoring method obviously still have inconvenience and defects in structure and use, and need to be further improved urgently.
