[0036] Use the fixing bolts 4 to fix the side fixing plate 15 on the side wall 22 of the tunnel,

[0037] Step 5: Pour concrete and vibrate:

[0038] After the soil below the ground 21 is removed, pour concrete from the pouring ports 211 into the area below the ground 21, and insert the vibrating rod into the pouring ports 211 for vibration.

[0039] Step 6: Concrete solidification:

[0040] After the concrete solidifies, both the pouring ports 211 and the openings 221 are filled with concrete, and the loose soil below the ground 21 and on both sides of the bottom photographing light-emitting groove structure 1 is replaced by concrete, so that the concrete firmly adheres to the bottom photographing light-emitting groove structure 1;

[0041] Step 7: Cut off the support columns 14 and remove the positioning plate 3:

[0044] The present invention has the following effects compared with the prior art:

[0045] 1. In the bottom photographing light-emitting groove structure of the present invention, a number of support columns are vertically arranged between the two side plates of the bottom photographing light-emitting groove structure. After the concrete solidifies, the support columns are cut off. The function of the support columns is to support the two side plates to keep the fixed width unchanged before the cast concrete completely solidifies. The bottom photographing light-emitting groove structure of the present invention is used for photographing the bottom of highway vehicles.

[0046] 2. In the bottom photographing light-emitting groove structure of the present invention, a number of notch positioning bars are correspondingly arranged on the upper parts of the two side plates of the bottom photographing light-emitting groove structure. A positioning plate is inserted between every two correspondingly arranged notch positioning bars. Both ends of the positioning plate extend out of the two notch positioning bars and support on the ground. After the concrete solidifies, the notch positioning bars are cut off and the positioning plate is taken out. The functions of the notch positioning bars and the positioning plate are to make the upper right-angle side of the bottom photographing light-emitting groove structure flush with the ground after the concrete solidifies. When the vehicle is driving, the wheels will press on both sides of the light-emitting groove, protecting the edges and corners of the ground on both sides from being damaged by the wheels.

[0047] 3. The bottom photographing system of the present invention is used for a concrete road surface with a tunnel. The line-scanning camera is arranged in the tunnel. Placing the camera below the ground can reduce the inclination angle between the viewing angle and both sides of the vehicle bottom, thereby improving the picture shooting quality. Light-emitting grooves are arranged on both sides of the tunnel. When the vehicle passes over the tunnel, continuous scanned images of the vehicle bottom can be obtained.

[0048] 4. For the construction method of the bottom photographing system of the present invention, during the construction of the present invention, after the soil below is removed, concrete is poured from the pouring port to below the ground, and a vibrating rod is inserted into the pouring port for vibration. After the concrete solidifies, the pouring port is filled with concrete. The loose soil on both sides of the bottom photographing light-emitting groove structure below the ground is replaced by concrete, which not only firmly adheres to the bottom photographing light-emitting groove structure but also ensures that the ground on both sides of the light-emitting groove will not be damaged due to the loosening of the soil below.
