Abstract

The invention provides an assembly type box culvert structure continuous abutted seam deformation measuring device, system and method. The device comprises a first support, a second support and a measuring tool, wherein the first support and the second support are arranged on the two sides of a box culvert structure abutted seam respectively; and the measuring tool is mounted on the first support, and the measuring end of the measuring tool is in contact with the working surface of the second support. The problem of prefabricated box culvert abutted seam deformation measurement is solved, abutted seam data can be obtained with high precision, data analysis is facilitated, continuous opening and dislocation deformation at the joint within a section of range of the prefabricated box culvert can be measured by adopting the measuring device under the action of heavy segments and box culvert transport vehicles, the data precision is high, and the deformation amount of the prefabricated box culvert joint can be obtained more easily.

Description

technical field [0001] The disclosure belongs to the field of civil engineering field tests, and relates to a device, system and method for measuring continuous joint deformation of an assembled box culvert structure. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] At present, since the 1980s, especially in the 21st century, with the sustained and rapid economic development and the continuous innovation of high-tech, the field of tunnel and underground engineering has achieved unprecedented development. Among them, shield tunneling has gradually become a research hotspot at home and abroad due to its advantages of safety, environmental protection, speed, and convenience. The internal structure of shield tunneling is mainly composed of segments, box culverts, and driveway slabs. The internal structure forms include cast-in-place, prefabr...
