Description

Technical Field

[0001] This utility model relates to the technical field of immersed tube casting equipment, specifically to a casting device for an underwater immersed tube anchor. Background Technology

[0002] Pipeline anchors are hydraulic structures installed at horizontal bends in pipelines to prevent pipeline displacement. They are usually made of reinforced concrete and are mainly used for the outlet pipes of hydropower stations and pumping stations, as well as the pressure pipes of water supply projects. They are mainly used to fix pressure pipelines and prevent them from shifting. Pipelines are generally built at the bends in the pipeline, or when the straight pipeline is too long.

[0003] Typically, after the underwater immersed pipe construction across rivers is completed, permanent underwater concrete supports are constructed to secure the pipe and prevent displacement or shifting due to river fluctuations. Traditionally, wooden formwork is used for pipeline supports. However, since wooden formwork cannot be sunk, this method is only suitable for open-cut construction without water. If precast concrete formwork is used, the large weight of the formwork makes it difficult to position underwater.

[0004] Existing technologies, such as the Chinese patent with patent number ZL202321858190.1, "Precast Steel Mold for Underwater Sinking Pier Construction," disclose a solution where an integral frame is specially set on the outside of multiple sealing plates. This increases the overall weight and strength of the precast steel mold, ensuring that it can sink to the bottom of the water. This avoids the problem of not being able to use wooden formwork in underwater sinking pier construction, as is the case in existing technologies. However, in this solution, after the formwork is lowered and sits on the sinking pipe, the arched opening is not sealed, causing concrete to flow out from the arched opening during pouring, affecting the pouring quality. Utility Model Content

[0005] The purpose of this utility model is to provide a casting device for underwater immersed tube anchors, which solves the problem that concrete flows out due to the unsealed arch opening during the casting process of underwater immersed tube anchors, thus affecting the casting quality.

[0010] As a further technical solution to the above scheme, the casting template includes a front template and a rear template, with an arched opening located at the lower part of the front template and the rear template.

[0011] As a further technical solution to the above scheme, the pouring pipe is vertically installed on the upper part of the pouring template, and the lower part of the pouring pipe is aligned with the opening on the upper part of the pouring template; the hopper is installed on the upper part of the pouring pipe for conveying materials.

[0012] As a further technical solution to the above scheme, the casting pipe is configured as multiple pipes, which are connected by flanges.

[0013] Compared with the prior art, this utility model has the following advantages and beneficial effects: By setting an arched opening on the casting template to adapt to the installation of the immersed tube, after the casting template sits on the immersed tube, the upper part of the arched opening is filled by the immersed tube, and the lower part of the arched opening is sealed with a sealing component to prevent concrete from flowing out during the casting process and affecting the casting quality.
