Description

Technical Field

[0001] The present application relates to the field of integrated pipe gallery construction, and in particular to a temporary plugging structure of a reserved casing at an outlet of an integrated pipe gallery. Background Art

[0002] The integrated pipe gallery is an underground pipeline integrated corridor that integrates various engineering pipelines such as electricity, communications, gas, heating, water supply and drainage. The integrated pipe gallery is equipped with outlet nodes at intersections or as needed. Pipeline casings need to be reserved at the outlet nodes. Pipe groups or trenches are generally set from the outlet nodes to both sides of the road to ensure that the pipelines inside the corridor are led to both sides of the road and then reach the users. However, due to the construction period, uncertainty of the time for pipelines to enter the corridor, and long-term planning of reserved channels, the reserved casings at the outlet of the integrated pipe gallery cannot be closed in time or fully utilized. If the redundant holes are not closed, groundwater will penetrate into the interior of the pipe gallery, which will easily cause damage to the electrical components in the distribution box in the pipe gallery, moisture in the decorative layer of the wall of the pipe gallery, and corrosion of metal supports and hangers for a long time.

[0003] At present, the temporary plugging methods of integrated pipe corridors can be roughly summarized as follows: fine stone concrete plugging and rubber airbag plugging. Fine stone concrete plugging is extremely difficult to clean and remove as a temporary plugging filler, and the plugging process is cumbersome. Although rubber airbag plugging is simple to operate, the air pressure of the airbag needs to be checked regularly, and the rubber is prone to aging and loses its plugging effect.

The two ends behind the central axis of 110 respectively penetrate the center of two waterproof rubber gaskets 120 and the center of two casing sealing plates 130, and the connecting rod cap 150 and the fastening nut 160 are respectively provided on the fastening screw 140 with a nut gasket 300 located between the fastening nut 160 and the corresponding waterproof rubber gasket 120. A casing sealing plate 130 and the corresponding pressed waterproof rubber gasket 120 are respectively provided with a first filling hole 170 and a second filling hole 180 connected to the interior of the rigid waterproof casing 110. The rigid waterproof casing 110 is filled with a waterproof filling layer 190, and the waterproof filling layer 190 is a foam rubber layer; the rigid waterproof casing 110 is provided with an annular water-stopping steel plate 290 pre-buried in the concrete structure 100 of the corridor outlet.

[0032] The temporary plugging structure of the reserved casing of the integrated pipe gallery outlet provided in the embodiment of the present application first embeds the rigid waterproof casing 110 penetrating the concrete 100 of the pipe gallery outlet structure during the construction, and then sequentially passes the rod body of the fastening screw 140 through a casing sealing plate 130, a waterproof rubber gasket 120, the rigid waterproof casing 110, another waterproof rubber gasket 120 and another casing sealing plate 130, and then the connecting rod cap 150 presses against the side of another casing sealing plate 130, and then sequentially installs the nut gasket 300 and the fastening nut 160 on the fastening screw 140, so that the fastening nut 160 presses against the casing sealing plate 130 and the corresponding waterproof rubber gasket 120. The two casing sealing plates 130 are tightened by fastening screws 140 and the two waterproof rubber gaskets 120 are respectively pressed against the two sides of the tunnel outlet structural concrete 100, and the first filling hole 170 and the second filling hole 180 respectively provided on a casing sealing plate 130 and a corresponding waterproof rubber gasket 120 are aligned and connected to the interior of the rigid waterproof casing 110, and then the foam glue is sequentially passed into the interior of the rigid waterproof casing 110 through the first filling hole 170 and the second filling hole 180 until it is filled, and the foam glue inside the rigid waterproof casing 110 is solidified to form a foam glue layer, which is the waterproof filling layer 190.

[0033] The temporary sealing structure of the reserved casing at the outlet of the integrated pipe gallery provided in the embodiment of the present application uses a fastening screw 140 and a fastening nut 160 to tighten the two casing sealing plates 130 to press and fix the two waterproof rubber gaskets 120 on the two ends of the rigid waterproof casing 110 for sealing. At the same time, a first filling hole 170 and a second filling hole 180 are opened on the casing sealing plate 130 and a waterproof rubber gasket 120 to fill the rigid waterproof casing 110 with waterproof material to form a waterproof filling layer 190, thereby realizing a multi-layer waterproof structure and effectively improving the waterproof effect. At the same time, it has the advantages of simple, stable and reliable structure. The sealing structure can be loosened or tightened only by fastening the nut 160. On-site installation and removal are convenient and quick, and the construction efficiency is high.
