Description

Technical Field

[0001] The utility model belongs to the field of station construction, and in particular relates to an anti-collapse structure for a station main body and an auxiliary interface. Background Art

[0002] After the main station structure is completed, the supports will be removed, and the soil will be backfilled to the planned elevation before construction of the auxiliary enclosures and auxiliary structures begins. (Ancillary structures include air ducts and entrances and exits). Once the auxiliary structures are completed, the common enclosure between the main and auxiliary structures will be removed, and the remaining structures will be connected.

[0003] However, this approach poses a safety hazard. If the soil cover is deep and certain safety measures are not taken, when the main enclosure is partially chiseled out, the enclosure above the auxiliary top plate lacks constraints at the corners and is prone to overturning or falling piles under the action of lateral water and soil pressure, causing local landslides.

[0004] 1. A temporary retaining wall is constructed above the completed main structure to resist the water and soil pressure of the backfilled main structure. During the construction of the ancillary structures, the common retaining structure between the ancillary structures and the main structure is excavated as it is built. This practice increases the construction cost.

[0005] 2. The slope method is adopted. This method places too high requirements on the construction site, especially considering that after the main construction is completed, a large number of pipelines need to be moved back to the top of the main body. The slope plan has a great impact on the pipeline relocation plan.

[0006] Both approaches will incur a certain amount of additional construction costs. The second approach, in particular, while cost-effective, carries significant construction risks, such as the risk of the top retaining wall falling, tipping over, and collapsing when removing the retaining wall. Utility Model Content

[0007] From the perspective of construction cost control, this utility model proposes an anti-collapse structure for the interface between the station main body and the auxiliary under the premise of ensuring safety, which fundamentally solves the risk of broken enclosure structure at the interface position of the main body and the auxiliary, and provides safety protection for construction workers.

[0008] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical solutions: the anti-collapse structure of the interface between the station main body and the station accessories includes the station main body and the station accessories, a common retaining structure is arranged between the station main body and the station accessories, embedded reinforcement is arranged between the accessory top plate and the common retaining structure, and a post-cast strip area is reserved between the station accessories, the station main body and the common retaining structure. A crown beam is arranged on the top of the common retaining structure, the crown beam is fixedly connected to the first support, and a retaining wall is arranged on the top of the crown beam.

[0009] Furthermore, connecting steel bars are provided in the post-cast zone area, and the connecting steel bars connect the steel bars of the station attachment and the station main body through steel bar connectors pre-buried in the station attachment and the station main body.

[0010] Furthermore, the thickness of the station attachment close to the common enclosure structure is increased, and additional armpit corners are provided to connect with the attachment structure top plate and attachment bottom plate.

[0011] Furthermore, a waterproof membrane is provided at the contact point between the post-cast strip area and the station body and the common enclosure structure, and a steel-edged rubber waterstop and a waterstop strip are provided on the side where the post-cast strip contacts the station attachment.

[0012] Furthermore, the common enclosure structure is a enclosure pile or a ground-connected wall.

[0013] Compared to existing technologies, this new invention offers the following advantages: It connects the auxiliary roof plate and the common retaining structure into a single, integrated structure through the implantation of rebar. This L-shaped support structure, connected to the retaining structure via the implanted rebar, effectively creates a retaining wall, protecting against soil and ground overloads from the main body. Furthermore, after the retaining structure is removed, the common retaining structure is secured at the bottom by implanted rebar and connected at the top by a crown beam. Lateral loads transmitted from the structure are then applied, eliminating the risk of it falling. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following will describe the implementation of the present invention in detail with reference to the accompanying drawings and examples, so as to fully understand and implement the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects.

[0019] Example 1

[0020] like Figure 1As shown, the anti-collapse structure of the interface between the station main body and the auxiliary includes a station main body 1 and a station auxiliary 2, and a common enclosure structure 3 is arranged between the station main body 1 and the station auxiliary 2. The common enclosure structure 3 in this embodiment is a ground-connected wall. The station auxiliary 2 is close to the common enclosure structure 3, and the auxiliary top plate 4 and the auxiliary bottom plate are partially raised by a plate thickness, and are connected to the auxiliary top plate 4 and the auxiliary bottom plate by adding axillary angles. An embedded steel bar 5 is provided at the raised position of the auxiliary top plate 4, which is connected to the common enclosure structure 3 to form an L-support structure to ensure the transfer of horizontal loads. The number and size of the embedded steel bars are calculated and determined based on the actual situation on site.

[0021] A post-cast joint area 6 is reserved between the station attachment 2, the station main body 1 and the common retaining structure 3. Connecting steel bars are arranged in the post-cast joint area 6. The connecting steel bars connect the steel bars of the station attachment 2 and the station main body 1 through steel bar connectors embedded in the attachment top plate 4, the attachment bottom plate and the station main body 1, and then concrete is poured to connect them into an integral structure.

[0022] A cap beam 7 is provided at the top of the common enclosure structure 3, which is fixedly connected to the first support 8. A retaining wall 9 is provided on top of the cap beam 7. The first support and retaining wall 9 are used to provide auxiliary support when the common enclosure structure 3 is dismantled. After the post-cast structure at the interface position has developed strength, the soil is backfilled and the first support 8 can be removed.

[0023] In addition, waterproofing membrane 10 is installed at the contact point between the post-cast zone 6 and the station main body 1 and the common enclosure 3. A steel-edged rubber waterstop 11 and waterstop strip 12 are installed at the contact point between the post-cast zone and the station attachment 2. The steel-edged rubber waterstop 11 enhances the anti-seepage performance of the structural deformation and further improves the anti-seepage performance of the post-cast zone 6.

[0024] Example 2

[0025] like Figure 3 As shown, the difference between this embodiment and embodiment 1 is that the common retaining structure 1 adopts retaining piles. When retaining piles are adopted, an inter-pile net spraying 14 is set between the retaining piles and the backfill soil, and concrete is sprayed after the net is hung.

[0026] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
