Problems solved by technology

[0005] The problem with the above two methods is that the construction process of the airbag is cumbersome, and the on-site construction is difficult. It is more suitable for water stop in deep water conditions of large caps. For some shallower water levels, the construction process of the above two methods is more complicated. It is more difficult to make on-site , higher economic costs

Abstract

The invention discloses a prefabricated cap water-stop structure, which comprises a prefabricated cap post-pouring hole water-stop groove, which is ring-shaped; a supporting plate, which is ring-shaped and coaxially arranged under the prefabricated cap post-cast hole water-stop groove; Pile foundation, which extends into the water stop groove of the post-casting hole of the prefabricated cap, and a certain distance is between the pile foundation and the water stop groove of the post-cast hole of the prefabricated cap; There is a certain distance between the inner walls, which are filled with expanded rubber strips, and the expanded rubber strips swell with water to perform vertical water-tight sealing; wherein, a water-stop groove for the post-casting hole of the prefabricated cap is provided between the supporting plate and the prefabricated cap An annular water-stop ring is used for water-stop sealing in the horizontal direction; concrete is poured between the pile foundation and the water-stop groove of the post-cast hole of the prefabricated cap with the supporting plate as the bottom. In the present invention, the tray is used as the quick-setting mortar bottom mold to effectively seal the quick-setting mortar from the horizontal and vertical directions to ensure smooth pouring of the quick-setting mortar. After the quick-setting mortar reaches strength, the water stop is completed.

Description

technical field [0001] The invention relates to the field of water-stopping of prefabricated platforms. More specifically, the present invention relates to a prefabricated platform water-stop structure and method. Background technique [0002] With the development of bridge design and construction, it is more and more common for long-span water bridges to use prefabricated caps and piers, such as the Hong Kong-Zhuhai-Macao Bridge, Xiamen Second Passage, etc. At present, there are mainly two ways to stop water on the platform: [0003] One is the water-stop method of adding airbags to the floating box, that is, an annular floating box is arranged under the prefabricated platform, and a sealing device is arranged on the contact surface between the top of the annular floating box and the platform surface; and an annular inflatable airbag is arranged inside the floating box. The buoyancy provided by the floating box enables the sealing device to make the sealing device on the ...
