Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a tower crane enclosure and rainproof structure outside a basement. Background Art

[0002] During the construction process, according to the actual situation of some project sites, the tower crane needs to be set up at the fertilizer trough position close to the outer wall of the basement. The foundation elevation is lower than the elevation of the basement roof and the natural ground height. After the construction of the building basement is completed, the fertilizer trough involves backfilling. If there are no retaining measures around the tower crane foundation, the tower crane foundation and the bottom standard section will be buried by backfill soil. The previous method was to reserve the earth around the tower crane foundation without backfilling, and then backfill after the main capping tower crane was dismantled. This would cause the fertilizer trough to be backfilled late, and the road between the natural ground and the basement roof would be blocked, affecting the site layout. For this reason, a tower crane enclosure and rainproof structure outside the basement is proposed. Utility Model Content

[0003] The utility model aims to solve the above problems, thereby providing a tower crane enclosure and rainproof structure outside a basement.

[0004] The utility model solves the above problems and adopts the following technical solutions:

[0005] A tower crane enclosure and rainproof structure outside a basement comprises a tower crane foundation and a tower crane standard section, a retaining wall is built above the tower crane foundation, the top height of the retaining wall is higher than the natural ground height, the retaining wall is connected end to end and is arranged in a barrel-like shape around the outer periphery of the tower crane standard section, the retaining wall comprises a masonry layer and a concrete ring beam layer arranged at intervals, and a retaining cover is arranged above the concrete ring beam layer at the top of the retaining wall.

[0006] Compared with the prior art, the utility model adopting the above technical solution has the following outstanding features:

[0007] The utility model has a simple structure and is easy to construct. It utilizes the stress characteristics of the barrel structure of the retaining wall to ensure that the retaining wall will not become unstable and damaged when backfilling soil on the outside. After the basement construction is completed, the fertilizer trough in the area outside the retaining wall can be backfilled quickly. After backfilling to the natural ground height, a construction road is formed between the natural ground and the basement roof, which does not affect other plane layouts on the site.

[0008] As a preferred embodiment, a further technical solution of the utility model is:

[0009] A plurality of buttresses are integrally formed and built on the inner wall of the retaining wall to increase the structural strength of the retaining wall.

[0010] A cement mortar layer is provided on the outer wall of the retaining wall facing the soil, which increases the structural strength of the retaining wall and reduces the infiltration of external rainwater into the retaining wall.

[0011] A water collection well is arranged on one side of the tower crane foundation, and an upper cover is arranged above the water collection well. The upper surface of the tower crane foundation is a slope structure, and the side close to the water collection well is lower. A drainage pipe is arranged on the lower side, and one end of the drainage pipe passes through the retaining wall and the water collection well cover and is inserted into the water collection well to avoid water accumulation above the foundation in the retaining wall.

[0012] The top surface of the retaining cover is an inclined surface with a slope of not less than 20°, and the edge of the top surface extends to the outside of the retaining wall to prevent rainwater from flowing into the tower crane foundation. BRIEF DESCRIPTION OF THE DRAWINGS
