Description

Technical Field

[0001] The utility model relates to the technical field of quality detection devices, in particular to a shield section segment assembly quality detection device. Background Art

[0002] As a shield tunnel lining support structure, the quality of the pipe segment is closely related to the safety of the tunnel. A conventional pipe ring is a circle composed of 6 pipe segments, which is used to evenly bear the surrounding rock pressure and reduce stress concentration. The curvature of each pipe segment has a direct impact on the roundness of the pipe ring. Therefore, after the construction of the shield pipe segment is completed, the shield pipe segment assembly flatness will be tested. For example, "a portable shield pipe segment assembly quality inspection tool with publication number CN208620969U includes a bracket, and the bracket is respectively provided with an arc measuring device and a horizontal measuring device. The bracket includes a crossbeam and a support column connected to the crossbeam. The crossbeam is evenly provided with an arc measuring device, and the support column is provided with a horizontal measuring device, and the horizontal The measuring device is distributed parallel to the crossbeam, and the bracket, arc measuring device and horizontal measuring device are integrated into one piece. The arc measuring device is an arc plate, and the radius of the arc plate is the same as the radius of the shield segment to be measured. The horizontal measuring device is a spirit level with a bubble level on it, which can measure the assembly flatness and arc of the shield segment. It is not only convenient and fast, but also simple in structure and easy to carry. At the same time, the spirit level can also be used to measure the flatness of the tunnel. It serves two purposes in one, greatly improving the measurement efficiency. When workers of different heights use the device, shorter workers need to stand on tiptoe for detection, while taller inspectors need to bend over for detection, which is inconvenient for the workers to use.
