Description

Technical Field

[0001] This utility model relates to a subway overhead pipe gallery structure, belonging to the field of building engineering technology. Background Technology

[0002] Urban rail transit depots require large land areas. To address the shortage of urban land and increase land development returns, more and more cities are adopting the development model of developing platforms above subway depots. However, the development sequence and construction cycle of these platforms differ from those of subway depots. These factors place special requirements on the drainage of these platforms.

[0003] In existing technologies, the drainage of the top cover adopts, for example... Figure 5 The design shown, which involves creating a slope in the top cover layer to drain water to the side of the entire top cover structure (i.e., the upper edge of the top cover in the width direction) and then leading it to the ground, has the following problems.

[0004] 1) Due to the different development and construction cycles of the vehicle depot and the above-ground property, the secondary development of the above-ground property is generally later than the implementation time of the vehicle depot platform below, and the drainage needs of the two are different; the current above-ground structure can only collect roof drainage, and the drainage function is lost after the cover plate is covered with soil.

[0005] 2) The area occupied by the subway overpass is large, usually reaching more than ten hectares. Therefore, it is necessary to set up anti-seismic joints to divide the overpass into multiple independent anti-seismic units. The existing slope drainage design will inevitably pass through the structural anti-seismic joints, which will pose a great risk of water leakage at the joints and have an adverse impact on the operation of the depot.

[0006] 3) Conventional slope drainage methods can only be used when the width of the cover is relatively small, that is, when the slope length is short. If the slope distance is long, the surface layer thickness will be very large, which will not only increase the project cost, but also reduce the floor height of this floor and affect the user experience.

[0007] Before the completion of the roof development of the depot, the roof slab was not covered with soil. Although drainage pipes could be installed under the slab for drainage, this posed certain risks. On the one hand, drainage could occur directly on the ground within the depot, adversely affecting vehicle operations. On the other hand, installing drainage pipes directly under the slab could conflict with safety arrangements during subway operations, potentially hindering the timely repair and replacement of faulty drainage pipes and thus affecting normal drainage function. Utility Model Content

[0008] This utility model addresses the aforementioned shortcomings of existing technologies by proposing a subway overhead pipe gallery structure that can meet the drainage requirements of different development phases, facilitate the maintenance and replacement of faulty drainage equipment, and does not affect the operation of the vehicle depot during use.

[0013] Along pipe gallery extension direction, be equipped with deformation joint between different structure aseismatic unit, and be equipped with cast-in-place cover plate on the both sides of deformation joint respectively.

[0017] For some specific implementation, the pipe gallery top is further equipped with a cantilevered plate, and the board edge drainage ditch is arranged between the cantilevered plate and the prefabricated cover plate. When the main structure of the pipe gallery is close to the existing structure beam, the existing structure beam is used as the second structure beam, and the cantilevered plate is used to connect the board edge drainage ditch. Preferably, the cantilevered plate and the board edge drainage ditch are integrally poured and formed.
