Description

[0001] This utility model claims the priority of a Chinese patent application titled "A Pipe Encapsulation Anti-floating Device" with the application number 202422116121.4 and filed with the Chinese Patent Office on August 29, 2024. The entire content is incorporated herein by reference. Technical Field

[0002] This utility model belongs to the technical field of pipeline construction devices, and specifically relates to a pipe encapsulation anti-floating device. Background Art

[0003] During the construction of rainwater and sewage pipelines, small-diameter pipelines have the characteristics of "two smalls and one long being prone to floating". "Two smalls" means small working face, small demand for pipeline foundation and pipe encapsulation concrete. "One long" means relatively long pouring time under a certain volume of concrete. "Prone to floating" means that small-diameter pipelines are light in weight, and if the pouring speed of the encapsulation concrete is too fast, it is easy to cause the pipeline to float. In municipal engineering, generally, the construction site of rainwater and sewage pipelines is limited, and large-area excavation construction cannot be carried out. As Figure 1 shown, pipeline construction needs to first carry out pipeline foundation construction, then pipeline installation construction, and finally pipeline encapsulation construction. Especially during the construction of small-diameter pipelines such as d300 - d800, small-diameter pipelines are light in weight, and the pouring speed of the encapsulation concrete needs to be controlled, otherwise it is easy to cause the pipeline to float. Once the pipeline floats, it will lead to the pipeline line type and deviation not meeting the design and specification requirements, unable to ensure the designed flow velocity of the water flow, and even cause problems such as reverse slope drainage, siltation, and blockage of the pipeline. In severe cases, it can only be re-poured, resulting in huge energy and economic losses. And when the relative pouring time of the concrete becomes longer, it will further lead to a longer construction period of the pipeline, increasing the time cost and labor cost.

[0004] Patent document CN117627141A discloses a construction method for anti-floating of a large drainage pumping station's overbank pipeline and concrete pouring, which includes a concrete cushion layer, a steel pipe, concrete reinforcement for pipe wrapping, and a concrete wrapping layer. By sleeving the concrete reinforcement for pipe wrapping outside the steel pipe, both the steel pipe and the concrete reinforcement for pipe wrapping are poured inside the concrete wrapping layer, and a connecting component for increasing the adhesion force is provided between the steel pipe and the concrete wrapping layer. The concrete cushion layer is located at the bottom of the concrete wrapping layer. Although this method solves the problem of the pipeline being prone to floating during the concrete pouring process, its components cannot be recycled, the economy is poor, and the steel pipe as an inner lining has poor adaptability and is not suitable for pipelines of various diameters.
