Abstract
Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, and in particular to a temporary sealing structure applied to the handover area of basement construction processes. Background Technology
[0002] To meet people's growing living and spiritual needs, urban renewal and renovation are becoming increasingly frequent, such as installing elevators and adding underground parking garages. Furthermore, many basement constructions cannot be completed in one go and require phased construction, making the handling of connection points particularly important. Generally, a project's basement is a single, integrated project without structural gaps. However, some projects adopt a phased construction approach for underground works, where the steel reinforcement and waterproofing membranes pre-installed in the earlier phases are easily exposed, hindering subsequent construction and compromising construction quality. To address the protection issues of underground structural connection areas, this application designs a temporary sealing structure for basement construction area junctions. Utility Model Content
[0003] This utility model addresses the problems and shortcomings of existing technologies by providing a novel temporary sealing structure for the handover of basement work areas.
[0004] The present invention solves the above-mentioned technical problems through the following technical solution:
[0005] This utility model provides a temporary sealing structure for the junction of a basement work area, characterized in that: when there is an enclosure structure, a concrete retaining wall is set at a position perpendicular to the edge of the enclosure and the edge of the outer wall; when there is no enclosure structure, a concrete retaining wall is set at a position extending outward from the junction position by a first predetermined distance; a concrete baffle is erected on the top of the two opposing concrete retaining walls; the concrete baffle is a second predetermined distance away from the top of the basement structure; each concrete retaining wall is equipped with double-layer bidirectional steel bars; and the concrete baffle is equipped with double-layer bidirectional steel bars.
[0006] The positive and progressive effects of this utility model are as follows:
[0007] This invention effectively solves the quality problems of basement connection areas constructed in batches by adding temporary seals. These seals can be retained later to further enhance the waterproofing performance of the connection points. The seals can also be seen as a reinforcement measure for the basement, preventing disturbance to the basement connection points from the movement of construction vehicles.
[0008] This invention can effectively protect the waterproof membrane at the connection point; effectively protect the reserved reinforcing steel; effectively prevent backfill soil from falling, facilitate the protection of the on-site construction environment, and facilitate the cleaning of fallen soil; help enhance the waterproof performance of the basement connection point; and help reduce the risks (cracks, leaks, etc.) caused by the movement of construction vehicles.
