Description

Technical Field

[0001] The utility model relates to the technical field of pipe jacking engineering, in particular to a hole water stopping device. Background Art

[0002] Pipe jacking is a process of laying pipelines using trenchless technology. It can reduce the amount of demolition work along the pipeline and is suitable for use in scenarios where the road is narrow or there are structures above. During the pipe jacking construction process, in order to prevent the water and soil of the jacked soil layer from flowing into the construction well along the gap between the hole and the outer wall of the pipeline and to avoid the road surface on the pipe jacking line from sinking, a hole water stop device will be installed at the hole.

[0003] The existing water-stopping device for the opening of the jacking pipe has a relatively simple structure, and a sealing rubber ring is mostly used to seal the gap. However, the rubber ring will be subject to a certain degree of wear during use, resulting in a reduction in the sealing effect. Therefore, we propose a water-stopping device for the opening of the hole. Utility Model Content

[0011] The technical effect of adopting the above further solution is: by rotating the first threaded rod, it can drive the first arc plate to move inward inside the shell, so that the first sealing rubber ring fits with the top pipe, thereby improving the water-stopping effect.

[0012] As a preferred solution of the utility model, the first sealing rubber ring is bonded to the first arc plate.

[0013] The technical effect of adopting the above further solution is: the curvature of the first sealing rubber ring can be limited by the first arc plate, so that it can better fit with the top pipe and improve the stability in use.

[0014] As a preferred solution of the utility model, the second threaded rod is matched with the second threaded opening, and the second arc plate is rotatably connected to the second threaded rod.

[0015] The technical effect of adopting the above further solution is: through the rotational connection between the second threaded rod and the second arc plate, when the second threaded rod is rotated, the second arc plate can be prevented from rotating together, thereby improving the stability in use.

[0016] As a preferred solution of the utility model, the second sealing rubber ring is bonded to the second arc plate.

[0017] The technical effect of adopting the above further solution is: through the bonding of the second sealing rubber ring and the second arc plate, the connection between the two can be made more firm, thereby improving the stability in use.

[0029] like Figure 1-3As shown, the utility model provides a technical solution: a hole water-stopping device, comprising an embedded flange 1, a water-stopping component 2 is arranged on the front of the embedded flange 1, the water-stopping component 2 comprises a shell 201, a first threaded opening 202 is symmetrically provided at the top and bottom of the shell 201, a first threaded rod 203 is arranged inside the first threaded opening 202, the first threaded rod 203 extends to the inside of the shell 201 and is provided with a first arc plate 204, a first sealing rubber ring 205 is arranged inside the first arc plate 204, second threaded openings 206 are symmetrically provided on the left and right sides of the shell 201, a second threaded rod 207 is arranged inside the second threaded opening 206, the second threaded rod 207 extends to the inside of the shell 201 and is provided with a second arc plate 208, and a second sealing rubber ring 209 is arranged inside the second arc plate 208.

[0030] Example 2

[0031] like Figure 1-3 As shown, a third sealing rubber ring 101 is arranged around the back of the embedded flange 1, and the third sealing rubber ring 101 is bonded to the embedded flange 1. The third sealing rubber ring 101 can make the embedded flange 1 fit more closely with the hole, thereby improving the water-stopping effect. The first threaded rod 203 is adapted to the first threaded opening 202, and the first arc plate 204 is rotatably connected to the first threaded rod 203. By rotating the first threaded rod 203, the first arc plate 204 can be driven to move inward inside the shell 201, so that the first sealing rubber ring 205 fits with the top pipe, thereby improving the water-stopping effect. The first sealing rubber ring 205 is bonded to the first arc plate 204, and the first The arc plate 204 can limit the curvature of the first sealing rubber ring 205 so that it can better fit with the top pipe and improve the stability in use. The second threaded rod 207 is adapted to the second threaded port 206. The second arc plate 208 is rotatably connected to the second threaded rod 207. The rotatable connection between the second threaded rod 207 and the second arc plate 208 can prevent the second arc plate 208 from rotating together when the second threaded rod 207 is rotated, thereby improving the stability in use. The second sealing rubber ring 209 is bonded to the second arc plate 208. The bonding between the second sealing rubber ring 209 and the second arc plate 208 can make the connection between the two more firmly and improve the stability in use.

[0032] The working process of the utility model is as follows: when a hole water-stopping device is used and the rubber ring is worn due to friction with the top pipe during the hole water-stopping process, the first threaded rod 203 is first rotated in sequence to drive the first sealing rubber ring 205 to move toward the inside of the shell 201 through the first arc plate 204 until it is tightly fitted with the outer periphery of the top pipe again, and then the second threaded rod 207 is rotated to drive the second sealing rubber ring 209 to fit the outer periphery of the top pipe again through the second arc plate 208. The staggered arrangement of the first sealing rubber ring 205 and the second sealing rubber ring 209 can prevent external water from flowing in, and the worn sealing rubber ring is adjusted in position so that it can still fit tightly with the top pipe, thereby effectively improving the sealing effect of the hole.
