Description
Technical Field
The utility model relates to the field of construction, in particular to a immersed tube circular seam sealing and water stopping mechanism.
Background
When the cross-sea/river bridge is constructed underwater, pile foundations need to be built to support the bridge; usually, a plurality of steel pipes are driven to a bearing layer, then water is drained, and concrete is filled into the steel pipes. After the pile foundation is firmly fixed in water, a bearing platform and a pier can be built. Because the distance between the water surface and the sea/river bottom is larger, the length of the steel pipe is longer, and thus, the processing and transportation difficulty and the cost are increased.
