Description

Technical Field

[0001] The invention relates to a road collapse rescue device, in particular to a road collapse rescue and rapid drilling and backfilling drone in shield construction. Background Art

[0002] During the excavation process of shield tunneling, the ground collapse during and after the shield construction is often caused by unclear understanding of the stratum, improper construction measures, and unworkable emergency plans. Comprehensive analysis of the main reasons generally includes the following aspects: on the one hand, due to the excessive small setting of water and soil pressure, or excessive excavation caused by operational reasons during the excavation process, the stratum in front of the cutterhead is lost, causing ground collapse; on the other hand, due to the failure of synchronous grouting slurry to fill the gap between the rear segment of the shield tail and the stratum, the ground above the tunnel collapses after the excavation is completed; in addition, the leakage of the segments, connecting channel structures and other parts in the tunnel causes soil erosion, causing ground collapse. Since most of the urban subway lines are under the existing roads in the city, when collapse occurs, the existing concrete pavement of the road has a certain strength and will not sink with the soil under the road surface. At this time, the road seems intact, but in fact, it has collapsed underneath. When the vehicles and personnel on the road exceed the bearing capacity of the concrete on the road surface, a large-scale collapse will occur, causing people and vehicles to be buried. Summary of the invention

[0003] The purpose of the present invention is to address the defects and shortcomings of the above-mentioned prior art and provide people with a road collapse rescue and rapid drilling and backfilling drone in shield construction for non-excavation repair of collapsed areas.

BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a schematic diagram of the structure of the present invention.

[0010] Figure 2 It is a schematic structural diagram of the steel pipe and the conical cover of the present invention. DETAILED DESCRIPTION

[0011] like Figure 1 , Figure 2 As shown, the present invention is a fast drilling and backfilling drone for road collapse rescue in shield construction, which includes a movable body 1, and a drilling mechanism and a pile pressing mechanism are arranged in the body 1. A crawler 13 is arranged at the bottom of the body 1, and the crawler 13 can enable the body 1 to cope with various complex road surfaces. Balance legs 10 are arranged around the body 1, and the body 1 can be kept level by adjusting the balance legs 10.

[0012] The drilling mechanism includes a drilling power head 2 and a drill bit 3 provided on the front side of the vehicle body 1. A drilling motor 4 is provided on the drilling power head 2. The drilling motor 4 drives the drill bit 3 to drill downward through the drilling power head 2. Depending on the soil type, a coring drill bit 3 is required for reinforced concrete, and a straight drill bit 3 can be used for other soil types. The drill bit 3 is 1.5 meters long and can basically drill through the road stabilization layer to reach the original soil layer.

[0013] The pile-pressing mechanism comprises a steel pipe 5 vertically installed in the vehicle body 1, a clamp 6 is arranged on the side of the steel pipe 5, a pile-pressing plate 7 is fixed on the clamp 6, a plurality of oil cylinders 8 connected to the vehicle body 1 are installed above the pile-pressing plate 7, and an oil tank 11 and an oil cylinder motor 12 connected to the oil cylinder 8 are arranged on the vehicle body 1. The oil cylinder 8 can push the pile-pressing plate 7 and the steel pipe 5 downward or pull them upward; a conical cover 9 is movably inserted at the lower end of the steel pipe 5, and the conical cover 9 falls off automatically when there is no support below; a camera bracket is installed on the vehicle body 1, and after the camera bracket rotates to the top of the steel pipe 5, the camera can be lowered to the bottom of the steel pipe 5 to shoot the collapse; after the clamp 6 is released, the steel pipe 5 remains in place, and the grouting pipe of the concrete truck can be connected to the top of the steel pipe 5 to pour filler into the collapsed part.

[0014] Road collapse emergency quick drilling backfill operation: first select the drill bit 3 and start walking to the designated position. After reaching the designated position, open the balance leg 10 to keep the vehicle body 1 horizontal. Open the drilling mechanism and slowly drill down. When the drill bit 3 runs smoothly, the speed can be appropriately increased. If it is a reinforced concrete road surface, continue to drill down after drilling through the road surface. When the 1.5-meter drill bit 3 reaches the bottom, the thread of the top conical part of the drill bit 3 will get stuck in the concrete core, and the concrete core will be pulled up and pulled out. After drilling the hole, put away the balance leg 10, move the machine forward, and when the steel pipe 5 is aligned with the hole just drilled, support the balance leg 10 to make the vehicle body 1 horizontal. Then, push the pile plate 7 and the steel pipe 5 down to the top of the collapse through the oil cylinder 8, and continue to press down to a certain depth so that the conical cover 9 at the bottom of the steel pipe 5 will fall off by itself. Raise the camera bracket and rotate it to the top of the steel pipe 5, lower the camera from the top of the steel pipe 5 and turn on the lighting. The collapse condition is viewed from the video receiver. After checking the current situation, it is determined whether the road surface should be broken. If the road surface does not need to be broken, the camera is put away, the steel pipe 5 clamp 6 is loosened, the steel pipe 5 is left in the hole, and the vehicle body 1 is removed. The grouting pipe of the concrete truck can be connected to the top of the steel pipe 5 to inject filler into the collapsed area.

[0015] The present invention is mainly used for trenchless repair of collapsed areas. A hole is drilled by a drilling mechanism, and the vehicle body 1 is moved forward so that the pile-pressing mechanism is located above the drilled hole. The pile-pressing mechanism can press the steel pipe 5 into the drilled hole to reach the collapsed area. After the conical cover 9 falls off, the camera is lowered to the bottom of the steel pipe 5 to photograph the collapse condition; the grouting pipe of the concrete truck can be connected to the top of the steel pipe 5 to inject filler into the collapsed area.
