Description

Technical Field

[0001] This application relates to the field of comprehensive environmental management engineering, specifically to a dike reinforcement structure that can utilize pipelines within a river channel. Background Technology

[0002] Due to factors such as project land use and construction funding, a large number of existing sewage and water supply pipelines in Chinese cities are laid along rivers. This not only affects the aesthetics of the environment but also causes great inconvenience to the raising, reinforcement, and renovation of riverbanks and embankments. Currently, most comprehensive water environment management projects and river flood control projects adopt relocation methods when dealing with similar pipelines laid along rivers. This involves either dismantling the pipelines and reburying them below the riverbed, or laying them below the road on top of the embankment after the embankment is raised, or burying them on the back side of the embankment. However, relocation is costly and requires a long period of interruption in pipeline operation, seriously affecting the production and lives of urban residents.

[0003] Therefore, it is necessary to develop a structure that can preserve and utilize existing pipelines in the river channel, while simultaneously raising and reinforcing the river embankment, and also provide convenient access to the water for residents. Summary of the Invention

[0004] The purpose of this application is to provide a dike reinforcement structure that can utilize pipelines in river channels. This structure can retain and utilize existing pipelines in river channels, while simultaneously raising and reinforcing river dikes and providing convenient access to the water. It can also reduce land occupation, save investment, and shorten construction time.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] This application provides a levee reinforcement structure that can utilize pipelines within a river channel, including a gabion base installed at the bottom of the existing pipeline near the riverbank. An excavated material backfill area is provided above the gabion base. A waterfront platform is provided between the existing pipeline and the riverbank slope. The waterfront platform is located at the top of the excavated material backfill area. An ecological slope protection is provided between the waterfront platform and the top of the riverbank. A flood control wall is also provided on the top of the riverbank.

[0007] The gabion is a rectangle with a width of 1.5m and a height of 1m. It consists of a wire mesh cage made of woven metal wire and stones filled inside the cage to compact the silt and stabilize the riverbank.

[0008] The waterfront platform is constructed of pedestrian walkway bricks or permeable concrete, with a width of no less than 2m, and is equipped with protective railings on the water-facing side.

[0009] The slope ratio of the ecological slope protection is less than 1:1.5, and the slope protection adopts vegetation blocks or Reno mattresses, with a thickness of not less than 0.1m.

[0010] A sand and gravel cushion layer or a geotextile filter layer is installed below the ecological slope protection.

[0011] The flood control wall is a reinforced concrete L-shaped retaining wall. The horizontal part of the flood control wall is 0.4~0.6m thick and is buried below the ground of the top of the dike; the vertical part is 0.3~0.5m thick.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] 1. Preserve and utilize existing pipelines within the river channel to avoid relocation during river dredging construction, thereby saving investment and reducing social impact.

[0014] 2. Install gabion stone cages at the toe to compact the silt and stabilize the riverbank. They can be quickly filled underwater to block water and create dry conditions for other structures to be constructed, thus shortening the construction period.

[0015] 3. Located between the existing pipeline and the riverbank, it makes full use of the existing space and saves land. Attached Figure Description

[0020] like Figure 1As shown, this application embodiment provides a dike reinforcement structure that can utilize pipelines within a river channel, including a gabion base 2 installed at the bottom of the existing pipeline 1 near the riverbank. An excavated material backfill area 3 is provided on the upper part of the gabion base 2. A waterfront platform 4 is provided between the existing pipeline 1 and the riverbank slope. The waterfront platform 4 is located on top of the excavated material backfill area 3. An ecological slope protection 5 is provided between the waterfront platform 4 and the top of the riverbank. A flood control wall 6 is also provided on the top of the riverbank.

[0021] The existing pipeline 1 is the original structure, mostly concrete, cast iron or steel pipes laid along the riverbed near the bank slope of the original river channel. They are circular with a diameter of 0.5 to 2m, and some of the existing pipelines are wrapped with concrete.

[0022] Gabion Town Foot 2 is located at the bottom of the existing pipeline near the riverbank. It is a rectangle with a cross-section of 1.5m wide and 1m high. It consists of a wire mesh cage made of woven metal wire and stones filled inside the cage to compact the silt and stabilize the riverbank.

[0023] Excavated material backfilling area 3 is located at the foot of the gabion town. It is a nearby backfilling area for the excavated soil and rock materials from the slope repair, with a compaction degree of not less than 0.91.

[0024] Waterfront Platform 4 is located between the existing pipeline and the riverbank, on top of the excavated material backfill area. It is constructed of pedestrian walkway bricks or permeable concrete and is at least 2 meters wide. Protective railings are installed on the water-facing side.

[0025] Ecological slope protection 5 is set between the waterfront platform and the top of the riverbank, with a slope ratio gentler than 1:1.5. It adopts vegetation blocks or Reno mattresses for slope protection with a thickness of not less than 0.1m. Sand and gravel cushion layer or geotextile filter layer is set according to the geological conditions of the underlying surface.

[0026] Flood control wall 6 is a reinforced concrete L-shaped retaining wall, serving as a water-blocking and wave-damping wall. The top elevation of the wall is determined based on the design high tide level plus the calculated freeboard. The horizontal part is 0.4~0.6m thick and is buried below the ground level of the top of the dike. The vertical part is 0.3~0.5m thick. The length and thickness of each part are determined after stability and structural calculations based on the water-blocking height. The exterior facade will be beautified as needed.
