Problems solved by technology

[0004] 1. The position of the vault and the spandrel is relatively high, and the three-arm rock drilling jumbo or forklift is not professional equipment, and the protection measures are poor, which cannot guarantee the personal safety of the operator;
[0005] 2. It takes a long time to scan the second lining, and it is laborious to manually set up the antenna, which cannot guarantee the effect of close adhesion with the cave wall, which affects the signal reception;
[0006] 3 The scanning distance of the secondary lining is long, and the operator cannot guarantee the straightness of the measuring line, which is prone to up and down deviation, which affects the final detection result;
[0007] 4. The quality inspection can only be carried out along the axis of the tunnel, and the second lining inspection in the circumferential direction cannot be carried out;
[0008] 5. The road is occupied during the detection process, which affects the normal construction and traffic of the tunnel

Embodiment 1

[0057] Such as Figure 1-14 As shown, this embodiment discloses an automatic scanning device for the full measurement line of the tunnel second lining quality inspection based on an arc-shaped mounting frame, including an arc-shaped mounting frame 4, a moving trolley 5, a hobbing slide rail 14, and an antenna clamping device 15 And automatic scanning dolly 20.

[0058] Specifically, such as figure 1 , figure 2 , image 3 As shown, the arc-shaped installation frame 4 includes a groove-shaped arc-shaped body structure, and the outer contour of the body is the same as the arched shape of the tunnel. Further, two mutual The parallel spring chute 1 is provided with two parallel hobbing slides 3 on the lower top surface inside the body, and the hobbing slides 3 and chute 1 are also parallel to each other; the hobbing slides 3 The overall shape of the chute 1 is consistent with the overall shape of the mounting frame, and its shape is also arched, which is relatively close to th...

Embodiment 2

[0080] Utilize the automatic scanning device of the full measuring line of tunnel second lining quality detection described in embodiment 1, the method for detecting is as follows:

[0081] A. According to the shape of the tunnel wall 26, inlaid arc-shaped installation frames 4 on the hole wall at intervals in the axial direction of the tunnel, and installed the mobile trolley 5 into the arc-shaped mounting frames 4; Two mobile trolleys are installed in the frame; the two mobile trolleys are installed up and down;

[0082] Further, the installation method of the arc-shaped installation frame 4 on the side wall of the tunnel may be to punch a hole on the side wall, and then fix it on the side wall of the tunnel by screws, bolts and the like.

[0083] Further, the number of arc-shaped mounting frames 4 to be installed is selected according to the length of the tunnel. In principle, the longer the tunnel, the more the number of installations.

[0084] Further, the arc-shaped mou...

Abstract

The invention discloses a full-line automatic scanning device for tunnel second lining quality detecting and method. The full-line automatic scanning device comprises an arc mounting frame having an arc structure, a moving mechanism, first tracks, an automatic scanning mechanism being able to move along the tracks, and an antenna clamping device. The arc mounting frame is installed by being in contact with the arc contour of a tunnel. The moving mechanism installed in the arc mounting frame can move along the arc mounting frame. The first tracks are installed at the moving mechanism along thetunnel axis direction. The antenna clamping device installed at the automatic scanning mechanism is used for clamping an antenna.

Description

technical field [0001] The invention relates to an automatic scanning device and a detection method of a full measuring line for quality detection of the second lining of a tunnel, and specifically belongs to the field of radar detection of the quality of the second lining of a tunnel. Background technique [0002] Our country is in a period of vigorously developing infrastructure, and there are still many tunnels under construction and yet to be constructed. The secondary lining of the tunnel plays an aesthetic role in the tunnel, supports the surrounding rock, and serves as a stress reserve for the supporting structure. The construction quality of the secondary lining is one of the key factors affecting the overall construction quality and aesthetics of the tunnel. During the construction of the secondary lining, due to various reasons such as construction technology, there are often voids in the secondary lining and the gap between the primary lining and the secondary lin...
