Description

Technical Field

[0001] This utility model relates to an anti-settlement structure, and more particularly to an anti-settlement structure used between the outer wall of a basement and the retaining piles. Background Technology

[0002] With the increasing prevalence of underground engineering, deep foundation pits are now commonplace in the engineering industry. All deep foundation pit projects involve backfilling and sealing the pit after the basement structure's roof slab has been poured. Design specifications typically impose high requirements on the compaction density of the backfill soil to prevent road surface subsidence caused by later backfill settlement, which could lead to safety hazards. However, due to site conditions, the space within the foundation pit is often insufficient for compaction of the backfill soil; backfilling without compaction has become a common practice in the industry. In later stages of construction, tasks such as lifting curtain wall glass with cranes and pouring concrete for landscape pavements often involve the movement of heavy equipment. Since there is no structural support within the foundation pit area, this poses significant construction safety risks. Therefore, there is an urgent need to develop a settlement-resistant structure with high support capacity to meet construction requirements. Utility Model Content

[0003] The purpose of this invention is to provide an anti-settlement structure between the outer wall of a basement and the retaining piles. This invention effectively improves the anti-settlement capability.

[0004] The technical solution of this utility model is as follows: a settlement prevention structure between the outer wall of a basement and the retaining piles, comprising a retaining structure and a basement structure, wherein a settlement prevention beam-slab structure is provided between the retaining structure and the basement structure; the settlement prevention beam-slab structure includes a cast-in-place beam located inside the retaining structure, and a reinforced concrete cover plate is provided above the cast-in-place beam, wherein the reinforced concrete cover plate corresponds to the top of the retaining structure and the basement structure respectively.

[0005] The aforementioned anti-settlement structure between the outer wall of a basement and the retaining piles includes retaining piles, a capping beam at the top of the retaining piles, a support beam on the inner side of the retaining piles, and a corbel connected to the retaining piles below the support beam.

[0006] The aforementioned anti-settlement structure between the outer wall of the basement and the retaining piles uses a corbel anchored into the retaining piles and support beams by diagonal steel bars.

[0007] The aforementioned anti-settlement structure between the outer wall of a basement and the retaining piles includes an outer wall of the basement structure and a roof slab of the basement structure.

[0008] The aforementioned anti-settlement structure between the outer wall of the basement and the retaining piles also includes backfill soil between the retaining structure and the basement structure.

[0009] Compared with existing technologies, this utility model utilizes an anti-settlement beam-slab structure, consisting of cast-in-place beams and a reinforced concrete slab covering the tops of both the retaining structure and the basement structure, to achieve an anti-settlement mechanism between them. This structure connects to the backfill soil covering the area between the retaining and basement structures. This design effectively improves anti-settlement capabilities, avoids safety hazards during later construction, and ensures a flexible connection between the anti-settlement structure and the basement structure, reducing the impact of external structural deformation on the main structure. Furthermore, this application adds corbel structures within the retaining structure, located at the connection points between the support beams and retaining piles, to enhance the support capacity of the anti-settlement structure and further prevent safety hazards during later construction. In summary, this utility model effectively improves anti-settlement capabilities. Attached Figure Description
