Description

Technical Field

[0001] The utility model belongs to the technical field of hydropower construction, and in particular relates to a hydropower casing plugging pre-embedded device. Background Art

[0002] The embedded casing is a hole reserved for pipes to pass through brick walls, concrete beams, concrete walls and other components. It is suitable for civil air defense, underground engineering, chemical industry, steel, tap water, sewage treatment and other pipelines that pass through walls and require strict waterproofing. For example, hot and cold water casing, HVAC casing, etc. In the prior art, both ends of the casing are sealed with tape.

[0003] The processing of the sleeve fixed by tape sealing and welding is time-consuming, unsightly and has a high quality risk. During processing, tape is needed to wrap and seal the sleeve mouth. When installing the sleeve, it needs to be welded to the beam reinforcement. When welding, not only a welding gun is required, but also the installation time is invisibly prolonged. At the same time, when tape is used for wrapping and sealing, the tape sealing the sleeve is easily melted by high temperature during welding, causing the sealing tape to be damaged. When pouring concrete, the mold inspector needs to check carefully and eliminate them one by one. If they are not discovered and repaired in time, rework and sleeve blockage after pouring will occur. Garbage is easily generated when the mold is removed and unblocked, which pollutes the environment and is not conducive to civilized construction at the construction site.

[0004] At present, a cap is also used to seal the embedded casing, but the embedded casing still needs to be fixed on the beam reinforcement, formwork or other components that need to be installed and connected by welding, which prolongs the installation time of the casing body. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a pre-buried device for sealing a hydropower casing, which adopts prefabricated connecting parts on the embedded casing and combines with sealing parts to directly install and seal the two ends of the embedded casing, thereby shortening the installation and processing of the embedded casing, etc., which is time-consuming, unsightly and has high quality risks.
