Detailed Description
The anti-floating structure at the interface between the main body and the auxiliary structure of the underground station provided by the embodiment will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, the schematic structural diagram of the anti-floating structure at the main body and the auxiliary structure of the underground station provided by the present embodiment includes a main body structure 1 and an auxiliary structure 2 disposed on a side surface of one side of the main body structure 1 and communicated with the main body structure 1, the outer side surfaces of two sides of the main body structure 1 are both connected with a main body enclosure 3, an anti-floating beam 4 protruding outwards along a direction away from the main body structure 1 and extending along a length direction of the main body structure is fixedly disposed on the outer side surface of one side of the main body structure 1, a C-shaped beam 5 having an opening matched with the anti-floating beam 4 is fixedly disposed on a top of the main body enclosure 3 on the side, the anti-floating beam 4 is clamped in the opening of the C-shaped beam 5, and a bottom plate of the auxiliary structure 2 is disposed above the C-shaped beam 5.
The anti-floating beam 4 is clamped into the opening of the C-shaped beam 5, namely the main enclosure structure 3 and the main structure 1 are limited in the vertical direction, so that under the condition that the main enclosure structure 3 is separated from the main structure 1, the anti-floating requirement of the main structure 1 can be met by the self weight of the main enclosure structure 3 and the side friction resistance between pile soil. Compared with the traditional anti-floating structure, the anti-floating structure provided by the embodiment reduces the excavation amount and the backfill amount of the foundation pit, so that the main body enclosure structure 3 is more regular, and the engineering implementation cost and the construction risk are reduced. Furthermore, in the embodiment, the arrangement form that the anti-floating beam 4 is clamped into the opening of the C-shaped beam 5 can effectively ensure the integrity of the main body structure 1, avoid the occurrence of the concave part on the side part of the main body structure, and effectively improve the durability of the main body structure. In addition, the main body enclosure 3 can be any one of a main body enclosure wall or a main body enclosure pile, and in the present embodiment, the main body enclosure 3 is specifically selected as the main body enclosure pile.
Further, in the present embodiment, a mattress layer 6 is disposed between the bottom plate of the attachment structure 2 and the C-shaped beam 5 to ensure the levelness of the bottom plate of the attachment structure 2. Further, waterproof layers are arranged between the anti-floating beam 4 and the C-shaped beam 5, between the C-shaped beam 5 and the mattress layer 6, and between the mattress layer 6 and the bottom plate of the auxiliary structure 2, so that the waterproof performance is guaranteed.
