Embodiment Construction
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them.
[0021] refer to Figure 1-4 , a plugging device for pre-buried channel holes for rail transit, comprising a housing 1, the housing 1 is provided with two first through holes, and the inside of the first through holes is respectively slidably connected with a first sliding column 2 and a second The sliding column 3 is provided with a cavity 25 inside the housing 1, and the inside of the cavity 25 is slidably connected to the limiting plate 4. The inner wall of the cavity 25 is provided with a slide rail that cooperates with the sliding of the limiting plate 4, which is convenient for the sliding of the limiting plate 4. The plate 4 is provided with a fir...

The invention discloses a plugging device of a pre-buried channel hole for rail traffic. The plugging device comprises a shell, wherein two first through holes are formed in the shell, a first slidingcolumn and a second sliding column are slidingly connected with the interior of the first through holes respectively, a cavity is formed in the shell, a limiting plate is slidingly connected with theinterior of the cavity, a first groove and a second groove are formed in the limiting plate, limiting blocks are respectively welded on the side walls of the first sliding column and the second sliding column located inside the cavity, the two limiting blocks are respectively located in the first groove and the second groove of the limiting plate, the lower ends of the first sliding column and the second sliding column are fixedly connected with a first fixing column and a second fixing column respectively, the first fixing column penetrates through the shell, and a placement groove is formedin a position, corresponding to a pre-buried block, of the bottom of the shell. The pre-buried block in the plugging device is convenient to mount and detach, can be reused after being detached, andthe cost is reduced.
Description
technical field [0001] The invention relates to the technical field of rail transit, in particular to a plugging device for a pre-buried channel hole for rail transit. Background technique [0002] In rail transit, the plugging device is used to block the holes of the porous pre-embedded channels to prevent the concrete slurry from flowing into the channels during the prefabrication process. After the prefabrication is completed, the rubber plugs are removed to facilitate the installation and use of the channels in the later stage. It is inconvenient to install and disassemble the pre-embedded block in the plugging device of the pre-embedded channel hole for rail transit, and the plugging device is damaged after the pre-embedded block is removed from the pre-embedded channel hole, which cannot be recycled and reused, wasting resources ,higher cost. Contents of the invention [0003] The purpose of the present invention is to solve the inconvenient installation and disasse...
