Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0029] like figure 1 Shown, embodiment 1, a kind of segment true roundness detection method, the steps are as follows:

[0030] S1: Place the detection device inside the segment to be tested. The outer wall of the drum 6 of the detection device is provided with a laser ranging sensor 5. The rotation axis of the drum 6 is parallel to the axis of the segment to ensure that the points detected by the laser ranging sensor 5 are all in the in the same plane;

Abstract

The invention discloses a segment true roundness detection device and a detection method, which solves the problem that the segment posture is difficult to detect in the prior art. The steps of the present invention are as follows: the detection device is placed inside the segment to be measured, the outer wall of the drum of the detection device is provided with a laser distance measuring sensor, the rotation axis of the drum is parallel to the axis of the segment; the driving mechanism of the detection device drives the drum to rotate, and the laser range measurement The sensor measures the distance from the detection point on the inner wall of the segment to the laser ranging sensor, and transmits the distance signal to the background controller. An encoder is provided on the driving mechanism, and the encoder transmits the angle signal of the drum rotation to the background controller; the present invention When the shield tunneling machine segment is assembled into a ring shape, the roundness detection device can be installed at any position to detect the roundness of the segment with high precision, and grasp the assembly error of the assembled ring segment to correct the next ring The assembly of the tube is easy to operate and the amount of calculation is small, which can quickly and accurately measure the roundness of the tube.

Description

technical field [0001] The invention relates to the technical field of tunnel segments, in particular to a segment true roundness detection device and detection method. Background technique [0002] Shield machines generally adopt the method of assembling segments when excavating tunnels, and form newly excavated tunnels into tunnels with supporting linings. These tunnels can be used for subways, railways, highways, water diversion, underground pipe galleries, etc. Due to the uniform stress on the circular tunnel lining, it is widely used. The ring quality of the tunnel lining segment directly affects the quality of the tunnel after forming, and even affects the future use. Therefore, the circular tunnel plays an important role in the roundness detection of the lining segment. However, there is no high-precision roundness detection device for assembled segments at present. At present, under the existing shield construction conditions in my country, the posture of the segme...
