Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of the protection of catch wells and lift wells at the construction site of buildings, and particularly relates to a standardized temporary cover plate for catch wells and lift wells at the construction site of buildings. Background Technique
[0002] In the field of building construction, when the construction stage is after the basement raft slab is poured and before the basement floor is poured, the foundation pits such as catch wells and lift wells are usually protected by setting up vertical protection and covering with wooden formwork. The basement is below the plus-minus zero, and the basements of some high-rise buildings are buried very deep. The basement floors of many high-rise buildings are generally below the groundwater level. Therefore, some catch wells with large diameters are set up in the basement to collect the rainwater in the basement or flowing into the basement, which also causes the basement to be in a humid state all year round before the decoration stage.
[0003] At present, the protection of catch wells and lift wells at the building construction site is usually carried out by setting up vertical protection or covering with wooden square timbers and formwork. Setting up vertical protection can provide an obvious sign at the construction site, but when plastering and whitewashing the wall before pouring the basement floor, the vertical protection usually needs to be removed, which also increases the risk of personnel falling into the well and is not conducive to on-site safety management. The method of covering with wooden square timbers and formwork can solve the risk of personnel falling, but due to the humid environment characteristics of the basement, the wooden square timbers and formwork are easy to be corroded, and their own strength becomes weak after a long time, which is difficult to meet the on-site requirements and safety management requirements. Moreover, there are various sizes of wellheads on the site, and the existing protection methods cannot be adjusted according to the size of the wellhead, resulting in poor applicability.
[0004] How to solve the above problems is the research topic of this solution. Content of the Utility Model
