Technical Field

[0001] This utility model relates to the field of tunnel foundation clearing construction technology, and in particular to a device for rapid foundation clearing of the foundation of a pumped storage power station highway tunnel. Background Technology

[0002] In the construction of highway tunnels for pumped storage power stations, clearing the tunnel floor is a crucial step. After the tunnel is excavated using the drill-and-blast method, the floor will be left with impurities such as gravel, blasting powder, and mud. Highway tunnel construction has high requirements, and under normal circumstances, secondary concrete lining is necessary. To ensure the overall stability and safety of the tunnel structure, the floor must be thoroughly cleaned before the secondary lining concrete is poured. Traditionally, highway tunnel floor clearing is done manually, requiring multiple workers using shovels, brushes, and other tools, performing multiple steps including sweeping, shoveling, collecting, and flushing. This method is not only slow and inefficient, but also consumes a large amount of manpower and poses significant safety risks, severely restricting the tunnel floor construction progress and affecting the overall tunnel construction schedule.

After the excavator 5 removes the bucket, it can quickly connect to the conversion joint 1 of the device through the pins 101 using the quick converter of the excavator 5, and then carry out the foundation cleaning operation of the tunnel bottom slab.

[0020] Furthermore, the conversion connection unit includes a conversion connector 1, a pin 101, an ear sleeve 102, an ear plate 103, a connecting block 104, an upper rib plate 105, and an upper steel plate 106. The dimensions of the pin 101, ear sleeve 102, and ear plate 103 must correspond, and the thickness of the steel plate used in the conversion connector 1 should not be less than 10mm. Q345 steel plate is used, and it is also for balanced stress distribution. The ear plate 103 is a plate shape that is wider at the top and narrower at the bottom. The upper steel plate 106 has a vertical... Two parallel ear plates 103 are welded together; the two parallel ear plates 103 are fixedly connected by a connecting block 104; the narrow end of the ear plate 103 is welded and fixed to one side of the upper steel plate 106; the wide end of the ear plate 103 is provided with two ear sleeves 102; the two parallel ear plates 103 are respectively connected by two pins 101; the side of the upper steel plate 106 that is welded to the ear plate 103 is fixed by two parallel upper rib plates 105.

[0021] Further, the cleaning unit includes a brush head box 2, a lower steel plate 201, and a lower rib plate 203; the brush head box 2 is composed of a side plate 202, a reinforcing plate 204, a clamping plate 205, and steel wire ropes 206, wherein the thickness of the lower steel plate 201, the lower rib plate 203, the side plate 202, and the reinforcing plate 204 is not less than 10mm; multiple equally spaced clamping plates 205 are vertically welded to one side of the lower steel plate 201; both ends of the clamping plates 205 are welded and fixed to the lower steel plate 201 through the side plate 202; a reinforcing plate 204 is welded to the outer side of one end of the side plate 202, and the reinforcing plate 204 is tightly attached to the side plate to enhance the stress; one side of the side plate 202 is welded and fixed to the lower steel plate 201 through two lower rib plates 203; multiple steel wire ropes 206 are vertically filled between the multiple equally spaced clamping plates 205, and the clamping plates 205 and the... A groove is provided at the connection and fixing point of the wire rope 206 to increase the contact area between the clamping plate 205 and the wire rope 206, thereby improving the stability of the brush head. The clamping plates 205 are tightened and fixed by multiple bolts B207 passing through them. The thickness of the clamping plate 205 is not less than 20mm, and it is made of Q345 steel plate.

[0022] When in use, after the device arrives on site, it is moved near the clearing work surface. First, the bucket of excavator 5, in conjunction with a transfer machine or dump truck, is used to clear large pieces of gravel. After the large pieces of gravel are cleared, the bucket of excavator 5 is removed, and the device is connected to its adapter 1 via the excavator 5's quick connector for tunnel floor clearing. During the clearing process, the device should be swept close to the rock surface, avoiding excessive pressure to prevent severe damage to the wire rope brush head.

When clearing the floor, a backward method is used, sweeping sequentially from left to right or right to left. Powdered residue remaining in uneven areas can be cleaned by 2-3 people, solving the difficulties of traditional manual clearing, accelerating construction progress, reducing costs, and enhancing on-site construction safety.
