Description

Technical Field

[0001] The present application relates to the field of tunnel construction equipment, and in particular to a device for quickly removing reserved openings of steel pipe segments at tunnel construction inspection wells. Background Art

[0002] The inner diameter of the municipal stormwater pipeline currently under construction is 3 meters. The tunnel is constructed using the shield method. The tunnel is assembled from concrete segments, with steel segments installed where openings are required. Ground inspection wells are required for the municipal stormwater pipeline. These wells are located in two rings of steel segments with reserved openings. During tunnel construction, two semicircular steel sealing plates are installed in the reserved openings. After the well wall structure is completed, the two sealing plates are removed from the steel segments, allowing the well to connect to the tunnel.

[0003] However, after the steel pipe segments are formed into rings, they will be squeezed and dislocated during the load-bearing process, causing the sealing steel plate to tightly abut against the steel pipe segments and the connection to be firm, making the removal process of the sealing steel plate more difficult and laborious, thereby reducing the construction efficiency of the inspection well.

[0004] With respect to the above-mentioned related technologies, the inventors believe that after the steel pipe segments are formed into a ring, the better force effect makes the disassembly process of the sealing steel plate difficult, thereby reducing the construction efficiency of the inspection well.

The telescopic component 31 is connected to the connecting component 32 .

[0035] The telescopic assembly 31 includes a mounting block 311 having a mounting slot 3111 defined therein. A first hydraulic rod 312 and a second hydraulic rod 313 are fixedly mounted in the mounting slot 3111. The first hydraulic rod 312 and the second hydraulic rod 313 are disposed on opposite sides of the mounting slot 3111. A connecting handle 314 is fixedly mounted on one end of the mounting block 311 away from the mounting slot 3111.

[0036] The connecting assembly 32 includes a first adjustment block 321 fixedly connected to the first hydraulic rod 312, a second adjustment block 322 fixedly connected to the second hydraulic rod 313, a first adjustment slot 14 defined in the first sealing steel plate 1, and a second adjustment slot 23 defined in the second sealing steel plate 2. By inserting the first adjustment block 321 into the first adjustment slot 14 and the second adjustment block 322 into the second adjustment slot 23, the connecting assembly 32 is connected to the first sealing steel plate 1 and the second sealing steel plate 2, respectively.

[0037] The first adjustment block 321 is slidably connected to the first adjustment slot 14. A limit plate 141 is provided at the opening of the first adjustment slot 14 to limit the sliding movement of the first adjustment block 321. A connection port 142 is provided at one end of the first adjustment slot 14 near the first mounting plate 11. The second adjustment slot 23 has the same structure as the first adjustment slot 14.

[0038] Reference Figure 4 The first sealing steel plate 1 is provided with a mounting slot 15, and the clamping plate 12 is slidably connected to the mounting slot 15.

The rotation control assembly 17 includes a connecting rod 171, a first bevel gear 172, and a second bevel gear 173, which are rotatably connected to the first sealing steel plate 1 through a bearing. The first bevel gear 172 is fixedly provided on the screw rod 161, one end of the connecting rod 171 extends into the mounting slot 15 and is fixedly connected to the second bevel gear 173, and the other end of the connecting rod 171 extends out of the mounting slot 15 and is fixedly connected to an adjustment handle 174. The first bevel gear 172 is meshed with the second bevel gear 173.

[0039] The implementation principle of the device for quickly removing the reserved hole of the steel pipe segment at the inspection well of the tunnel construction in the embodiment of the present application is as follows: when installing the first sealing steel plate 1 and the second sealing steel plate 2, the adjusting handle 174 is rotated to make the clamping plate 12 extend out of the first sealing steel plate 1, so that the clamping plate 12 is clamped with the clamping groove 22, and the elastic sealing gasket 13 is abutted against the second sealing steel plate 2. When removing the first sealing steel plate 1 and the second sealing steel plate 2, the adjusting handle 174 is first rotated to make the clamping plate 12 move away from the second sealing steel plate 2, so that there is a gap between the clamping plate 12 and the clamping groove 22, and then the bolts on the first mounting plate 11 and the second mounting plate 21 are removed. The operator moves the mounting block 311 through the connecting handle 314, so that the first adjusting block 321 is inserted into the first adjusting groove 14 through the connecting port 142, and at the same time the second adjusting block 322 is inserted into the second adjusting groove 23. The first hydraulic rod 312 drives the first adjusting block 321 to slide in the first adjusting groove 14, and the limit plate 1 41 limits the sliding of the first adjustment block 321, and at the same time, the second hydraulic rod 313 drives the second adjustment block 322 to slide in the second adjustment groove 23. The first adjustment block 321 drives the first sealing steel plate 1 to move closer to the second sealing steel plate 2, and the second adjustment block 322 drives the second sealing steel plate 2 to move closer to the first sealing steel plate 1, so that the elastic sealing gasket 13 is squeezed and shrinks, thereby making the first sealing steel plate 1 and the second sealing steel plate 2 close to each other, thereby creating a gap between the first sealing steel plate 1 and its adjacent steel pipe segment, and creating a gap between the second sealing steel plate 2 and its adjacent steel pipe segment. The above structure improves the disassembly efficiency of the first sealing steel plate 1 and the second sealing steel plate 2, thereby improving the construction efficiency of the inspection well.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
