Due to the action of the plurality of universal wheels 402, the entire device can rotate while moving. When the entire device moves to the desired coring position, the staff stops pushing the handrail 101, and further the controller 3 controls the plurality of support frame controllers 501 to start working, thereby driving the plurality of support frames 502 to extend, further moving the plurality of support plates 503 downward. When the plurality of support plates 503 are close to the road surface, the controller 3 controls the support frame controller 501 to stop working.

When one of the core barrels 9 is facing the ground When the controller 3 controls the shaft rotation motor 607 to stop working, the controller 3 further controls the coring controller 8 facing the ground to start working. At this time, the multiple clamping plates 902 facing the ground are tightly attached to the inner wall of the coring barrel 9 facing the ground, so that the coring rod 801 facing the ground rotates downward, thereby causing the coring barrel 9 facing the ground to rotate downward, thereby driving the drill bit 901 facing the ground to rotate until it drills into the soil under the road surface, and further the clamping rod controller 906 facing the ground starts working. This drives the multiple clamping rods 904 facing the ground to contract, so that the multiple clamping plates 902 facing the ground move toward the fixed block 905, thereby clamping the road core. The controller 3 further controls the coring controller 8 to work in reverse, thereby completing the coring work. The staff further moves the entire equipment to the next coring point. The controller 3 further controls the shaft rotation motor 607 to work again, so that the coring barrel 9 that has not been cored faces the ground. The above operations are further repeated to complete the coring work again.
