Title:
UNDERGROUND SPACE CRACK MONITORING DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/272541
Kind Code:
A1
Abstract:
An underground space crack monitoring device and method. The device comprises: conductive sensing strips (7, 8, 9). The conductive sensing strips (7, 8, 9) are fixedly laid in a reserved seam (2) of an underground space to be detected; two ends of each of the conductive sensing strips (7, 8, 9) are provided with electrodes (10), and the electrodes (10) at the two ends of each of the conductive sensing strips (7, 8, 9) are connected to direct-current power supply modules (3, 12); a connection loop of each of the conductive sensing strips (7, 8, 9) and each of the direct-current power supply modules (3, 12) are connected in series with a direct-current resistance test module (11); and the direct-current resistance test modules (11) are communicationally connected to a control terminal (4). According to the underground space crack monitoring device and method, the stress-strain state of a structure can be mastered during construction and operation of an underground space structure, the occurrence and development process of a structure crack can be analyzed, and an accurate space position is provided for objectively and accurately determining whether the underground space structure crack affects or destroys the structure stability and reinforcing treatment of the structure crack.
