[0002] During the construction process, construction elevators are needed to transport building materials and components vertically. The foundation of the construction elevator is often set in the backfill area of the foundation pit. Since the backfill soil cannot reach the density of the original soil, it may cause uneven settlement of the elevator foundation in the backfill area, resulting in safety hazards during the operation of the construction elevator. If the elevator foundation is connected to the outer wall of the basement by anchor bolts, it is easy to cause water leakage in the basement of the building, affecting the use of the building.

[0004] The utility model adopts a technical solution to solve the technical problem: the elevator foundation for anti-settlement construction in the foundation pit backfill area includes a column pier, a protective wall, a beam pad, a platform beam, a foundation platform and an elevator foundation section, the column pier and the protective wall are located on the outer wall of the basement, the elevator foundation section is fixed on the foundation platform, a platform beam is fixed at the lower part of the foundation platform, one end of the platform beam is fixed on the beam pad on the original soil, and the other end is fixed on the column pier.
[0005] The area between the outer side of the basement and the original soil is a foundation pit backfill area, the elevator foundation section is located above the foundation pit backfill area, and the foundation pit backfill area is filled with backfill soil.
[0006] The column pier and the protection wall are formed by integrally building concrete blocks. The thickness of the protection wall is 200 mm, and the cross-sectional size of the column pier is 400 mm×400 mm.
[0007] There are two platform beams, each corresponding to a pier, and the distance between the two platform beams is determined according to the elevator model being constructed.
[0008] The platform beam and the foundation platform are formed by integral casting, and the beam pad is formed by concrete casting.
[0009] The top of the column pier and the top of the beam pad are in the same horizontal plane.
[0010] The beneficial effects of the utility model are as follows: the utility model structure utilizes the existing protective wall during the construction of the basement roll material waterproofing, and only two piers are built. One end of the platform beam utilizes the piers in the foundation pit backfill area to form a supporting structure, and the other end utilizes the stability of the original soil to form a stable support. The setting of the construction elevator foundation avoids damage to the basement roll material waterproofing layer. The protective wall and the piers are used as the construction elevator foundation, and there is no need to set up other basic structures. The structure is simple, safe and durable, and the uneven settlement caused by the construction elevator foundation being directly located in the foundation pit backfill area is avoided. The structure is safe and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The utility model is further described below in conjunction with the accompanying drawings:
[0016] As shown in the figure, this kind of anti-settlement construction elevator foundation in the foundation pit backfill area includes a column pier 1, a protective wall 2, a beam pad 3, a platform beam 4, a foundation platform 5 and an elevator foundation section 6. The column pier 1 and the protective wall 2 are located on the outer wall of the basement 8. The elevator foundation section 6 is fixed on the foundation platform 5. The lower part of the foundation platform 5 is fixed with a platform beam 4. One end of the platform beam 4 is fixed on the beam pad 3 on the original soil 7, and the other end is fixed on the column pier 1. The top of the column pier 1 and the top of the beam pad 3 are on the same horizontal plane, so that the foundation platform 5 is in a horizontal state during production. There are two platform beams 4, each corresponding to a column pier 1, and the spacing between the two platform beams 4 is determined according to the model of the elevator to be constructed. The outer side of the basement 8 and the original soil 7 are the foundation pit backfill area. The elevator foundation section 6 is located above the foundation pit backfill area, and the foundation pit backfill area is filled with backfill soil 9.
[0017] The column pier 1 and the protection wall 2 are formed by integral masonry of concrete blocks and are used to protect the waterproof layer of the basement exterior wall. The thickness of the protection wall 2 is 200mm, and the cross-sectional size of the column pier is 400mm×400mm. The spacing between the two platform beams 4 is 1800mm. The platform beam 4 and the foundation platform 5 are integrally cast. The thickness of the foundation platform 5 is 250mm, and the cross-sectional size of the platform beam 4 is 500mm×250mm. The beam pad 3 is located in the original soil 7 around the foundation pit and is formed by concrete casting. The size specifications are 100mm thick, 600mm wide, and 2400mm long.
[0018] The elevator foundation section 6 is fixed on the foundation platform 5. After the waterproofing construction of the basement exterior wall roll material, it is necessary to build the protective wall 2. At the same time, two column piers 1 are built according to the design requirements to support one end of the platform beam 4. After the construction of the outer protective wall 2 and the column pier 2 of the building basement 8 is completed, the foundation pit is backfilled and compacted. After the backfill soil 9 is backfilled to the bottom of the foundation platform 5, a beam pad 3 is set in the original soil area, and the elevator foundation section 6 embedded parts are pre-embedded. The foundation platform 5 and the platform beam 4 are cast as a whole, so that one end of the platform beam 4 is located on the upper part of the column pier 1, and the other end is located on the upper part of the beam pad 3. The foundation platform 5 is laid on the platform beam 3 to form the construction elevator foundation. The horizontality, installation position and size of the foundation platform 5 are checked, and the elevator foundation section 6 is installed.
[0019] The two sides of the construction elevator foundation platform beam are erected on piers and original soil, which not only avoids basement water leakage caused by direct connection to the basement outer wall, but also passes through the foundation pit backfill area to avoid the safety impact of uneven settlement of the backfill area on the elevator foundation. The structure is simple and the construction is safe and reliable.
[0020] In addition to the above embodiments, the present invention may also have other implementations. Any technical solution formed by equivalent replacement or equivalent transformation falls within the protection scope required by the present invention.
