Embodiment Construction

[0026] A device for measuring telescopic displacement of an underground retractable hollow mechanism, comprising a PC terminal 1, an above-ground module 2, and an underground module 3. The PC terminal 1 is connected to the above-ground module 2 , and the above-ground module 2 is in communication with the underground module 3 , and the underground module 3 is installed in the retractable hollow mechanism 4 .

[0027] The PC terminal 1 and the ground module 2 are on the ground, and jointly realize the control and modulation of the transmitted signal; the conditioning, frequency mixing and filtering, collection and processing, and distance measurement and display of the received signal.

[0028] The underground module 3 expands and contracts synchronously with the retractable hollow mechanism 4, and realizes signal laser emission, reception and photoelectric conversion during displacement measurement.

[0029] The PC terminal 1 is connected to the above-ground module 2 through a ...

Abstract

The invention provides a device for measuring the telescoping displacement of an underground telescoping hollow mechanism. The device comprises a PC terminal, an overground module and an underground module. The PC terminal is connected with the overground module which is in communication connection with the underground module. The underground module is installed in the telescoping hollow mechanism. The PC terminal and the overground terminal achieve control and modulation of emission signals, and conditioning, mixing filtering, acquisition processing and range finding display of receiving signals together. The underground module and the telescoping hollow mechanism synchronously telescope, thereby achieving signal laser emission, receiving and photoelectric conversion during displacement measurement. According to a method and the device for measuring the telescoping displacement of an underground telescoping hollow mechanism, control and measurement of telescoping displacement of an underground telescoping hollow mechanism can be achieved on the ground; working states of the telescoping mechanism can be monitored in real time; and effective data is provided for safety and quality evaluation of project construction.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a method and a device for measuring the telescopic displacement of an underground telescopic hollow mechanism. Background technique [0002] In the prior art, a retractable mechanism is used during civil engineering construction. The telescopic mechanism is placed underground and cannot be seen during construction. It is inconvenient to measure the size of the telescopic displacement of the telescopic mechanism. In addition, the underground environment is complex, and the working status of the telescopic mechanism is also inconvenient to know. How to find a solution to the displacement measurement method of the retractable mechanism in the underground concealed engineering in the field of civil engineering, and provide effective data for the safety and quality evaluation of engineering construction, has been perplexing engineers and technicians. Contents of the invention [00...
