Construction method of basement attached lane structure

Abstract

The invention discloses a basement attached lane structure and a construction method thereof. The basement attached lane structure comprises a lane bottom plate, an anti-stick and waterproof coiling material, a waterproof mortar base layer and a lane bottom plate concrete cushion layer; a basement exterior wall and a lane outer side wall are respectively arranged on two sides of a lane bottom plate, the lane bottom plate, the basement exterior wall and the lane outer side wall are structurally integrated, and the waterproof mortar base layer and the anti-stick waterproof coiling material are respectively integral structures with two bent sides. The construction method includes sequentially constructing a waterproof protecting layer, the lane bottom plate concrete cushion layer, the waterproof mortar base layer, the anti-stick waterproof coiling material, the basement exterior wall, the lane bottom plate and the lane outer side wall layer by layer. As the basement exterior wall, the structure of a lane and various structures in the horizontal direction and the perpendicular direction of a lane are structurally integrated as much as possible and are constructed simultaneously, a construction period can be effectively shortened, the structure is also stable, and the problems of crack and water leakage can be prevented effectively.

Description

technical field [0001] The invention relates to the technical field of driveway construction for public and civil buildings, in particular to a basement-attached driveway structure and a construction method thereof. Background technique [0002] With the improvement of architectural design level, the entrance of the driveway leading to the basement tends to be rational and artistic. During the design, the exit of the basement garage and the entrance of the municipal road meet the traffic flow requirements of the traffic hub, and the driveway is skillfully set on the podium of the high-rise building. In the concave corner position of the plane, most of them are attached to the outside of the outer wall around the basement, and the basement outer wall is used as the side wall of the driveway to obtain the effect that the driveway layout occupies a small area and is beautiful and practical. However, the deeper the negative floor of the basement, the longer the length of the ram...

AI Technical Summary

Problems solved by technology

The principle of this method is simple, and the construction operation is relatively simple, but the construction period is quite long, which is easy to affect the progress of the project.

In addition, when the driveway formed by this construction method is used, there are obvious defects: (1) construction joints are left at the connection between the basement exterior wall and the driveway floor, and the driveway floor will crack after a long period of use; (2) When backfilling the foundation pit, the compactness of the foundation pit backfill soil is difficult to reach the standard in a short time, so after the project is completed and used, due to the long-term settlement of the foundation pit backfill soil, the waterproof layer and protective layer under the driveway floor will be separated Even cracking, eventually resulting in water leakage and other phenomena; (3) backfilling the foundation pit too early in this construction method will cause the overall buoyancy of the basement to appear prematurely, affecting the quality of the project
