Description

[0001] The utility model relates to the technical field of underground engineering, in particular to a short-term blocking structure for a reserved opening in a subway station. Background Art

[0002] As the density of urban rail transit networks increases, the number of complex station types, such as transfer stations, is also increasing. In specific projects, a combination of near-term reservation and long-term construction is increasingly being adopted. Considering the functionality, economy, and timing of both near-term and long-term construction, the installation of escalator groups in public areas within stations for future transfers generally adopts a construction approach of "short-term reservation of civil engineering openings combined with long-term installation and implementation."

[0003] The reserved civil engineering openings in this area are mostly sealed in the near future using a concrete pouring structure, which will be demolished when used in the future. This conventional practice is cumbersome to construct and greatly increases the amount of civil engineering work. The demolition construction in the future will have a great impact on the normal operation of the station and the passengers' riding experience. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0018] A short-term blocking structure for a reserved opening in a subway station, comprising:

[0019] The reserved civil engineering opening edge beam 2 is set along the edge of the reserved opening. The reserved civil engineering opening edge beam 2 is made of concrete and is used to prevent the opening from collapsing and being damaged.

[0020] The embedded part 5 has one end extending out of the reserved civil engineering opening edge beam 2, and the rest of the embedded part 5 is embedded in the reserved civil engineering opening edge beam 2. The embedded part 5 is made of steel and is used as a fixing place for the baffle 7.

[0021] The baffle 7 is connected to the end of the embedded part 5 extending out of the reserved civil engineering opening edge beam 2. The baffle 7 is made of steel and is used to block the fish sauce hole. It can be removed at any time when construction is needed in the future, which is convenient, fast and low-cost.

[0022] The baffle structural beam 6 is disposed between the embedded component 5 and the baffle 7. One end of the baffle structural beam 6 is fixedly connected to the end of the embedded component 5 extending from the reserved civil engineering opening edge beam 2, and the other end of the baffle structural beam 6 is fixedly connected to the baffle 7. The embedded component 5 and the baffle structural beam 6 are fixedly connected by screws, and the baffle structural beam 6 is fixedly connected to the baffle 7 by screws. The baffle structural beam 6 is used to connect and fix the embedded component 5 and the baffle 7.

[0023] The structural plate 1 is arranged on the surface of the reserved civil engineering opening edge beam 2, and the structural plate 1 is used to protect the reserved civil engineering opening edge beam 2.

[0024] The water retaining sill 3 is arranged at the edge of the reserved civil engineering opening side beam 2 located in the outer direction of the reserved opening. The surface of the water retaining sill 3 is higher than the baffle 7, so it can prevent water from flowing into the inside of the opening.

[0025] The surface of the baffle 7 also has a decorative surface 8, which is consistent with the decoration inside the subway station.

[0026] The construction method is as follows: a civil engineering opening is reserved in the near future at the location of the escalator group used for future transfers in the public area of ​​the subway station, embedded parts 5 are embedded at the position of the edge beam 2 of the reserved civil engineering opening, and the baffle structure beam 6 and the embedded parts 5 and the baffle 7 are connected in sequence by bolts, and finally, the decoration construction method of the public area of ​​the station is implemented above the baffle 7 until the ground decoration of the public area is completed.

[0027] When the long-term renovation is implemented, the structural layer of the public area of ​​the station above the steel plate will be broken, and the baffle 7 will be removed from the baffle structural beam 6, and the baffle structural beam 6 will be removed from the embedded part 5 in turn, thus completing the entire demolition work of the recent blocking structure.
