Description

Technical Field

[0001] The utility model relates to the technical field of embankment engineering, and more particularly to an embankment drainage structure for alleviating embankment damage caused by heavy rain. Background Art

[0002] For small and medium-sized river management projects in northern China, the majority of measures for plain river sections involve raising and reinforcing embankments. These embankments are mostly earthen embankments, generally of low quality. Hardened pavement is generally not built on the embankment crests of non-critical river sections, and slope protection often relies on turf protection with grass seed sowing. During heavy rain, the embankment crests and slopes are susceptible to erosion, creating gullies. As the rainstorms persist, gullies deepen and widen, spreading toward the slopes and threatening the safety of the embankments and flood control efforts.

[0003] In some areas, concrete or masonry troughs and drainage ditches are installed on earthen embankments. During heavy rain, if the drainage ditches are not arranged in the right place for rainwater to collect, gullies and pits can easily form on the embankment, rendering the troughs and drainage ditches ineffective.

[0004] Therefore, there is an urgent need for a levee drainage structure that can reduce the damage to levees caused by heavy rain. Utility Model Content

[0005] The technical problem to be solved by the present invention is to provide a dike drainage structure which can reduce the damage to the dike caused by heavy rain, so as to solve the problems in the background technology.

[0006] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows.

[0007] A levee drainage structure for reducing damage to levees caused by heavy rain is provided on the top surface and slope surface of the levee, and includes longitudinal plastic blind ditches arranged along the two side edges of the top surface of the levee, and the longitudinal plastic blind ditches include an exposed portion and a buried portion; a plurality of transverse plastic blind pipes uniformly arranged laterally are provided on the top surface of the levee, and both ends of the transverse plastic blind pipes are connected to the buried portion of the longitudinal plastic blind ditch; a plurality of slope plastic blind ditches arranged along the slope are provided on the water-facing surface of the levee, the top ends of the slope plastic blind ditches are connected to the buried portion of the longitudinal plastic blind ditch, and the lower ends of the slope plastic blind ditches extend to the bottom of the levee and then extend horizontally for one section.

[0008] To further optimize the technical solution, the cross-section of the longitudinal plastic blind ditch is convex, and the exposed portion of the longitudinal plastic blind ditch is the same size as the curb.

[0009] To further optimize the technical solution, the buried part of the longitudinal plastic blind ditch is a 30cm×30cm plastic blind ditch.

[0010] To further optimize the technical solution, the spacing between the transverse plastic blind pipes is 5-10m, and the transverse plastic blind pipes are Φ100 transverse plastic blind pipes.

[0011] To further optimize the technical solution, the spacing between the plastic blind ditches on the slope is 20m.

[0012] Further optimizing the technical solution, the size of the slope plastic blind ditch is 30cm×30cm.

[0013] To further optimize the technical solution, the longitudinal plastic blind ditch, transverse plastic blind pipe and slope plastic blind ditch are all wrapped with anti-filtration geotextile.

[0014] Due to the adoption of the above technical solution, the technical progress achieved by the present invention is as follows.

[0015] This utility model provides a levee drainage structure that mitigates damage to levees caused by heavy rain. By evenly disposing longitudinal plastic blind ditches and transverse plastic blind pipes on the top surface of the levee to collect and divert rainwater, and by disposing a number of plastic blind ditches on the slope of the levee, rainwater is prevented from being excessively concentrated. This multi-point, surface-level drainage system reduces the extent of levee erosion caused by heavy rain. This utility model can significantly mitigate the formation of gullies on the top and slope of earthen levees under heavy rain conditions, thereby ensuring the safety of the levee and flood control. It has the advantages of low cost, fast construction, long service life, simple and low maintenance costs, and good drainage effectiveness. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] A levee drainage structure that reduces damage to levees caused by heavy rain, which is installed on the top surface and slope of the levee and is combined with Figures 1 to 2 As shown, it includes a slope plastic blind ditch 1, a water-facing surface of the embankment 2, a top surface of the embankment 3, a longitudinal plastic blind ditch 4, and a transverse plastic blind pipe 5.

[0021] Longitudinal plastic blind ditches 4 are installed along both sides of the embankment's top surface 3. These ditches consist of an exposed portion and an underground portion. The cross-section of the longitudinal plastic blind ditch 4 is convex, and the exposed portion is the same size as the curb. The underground portion of the longitudinal plastic blind ditch 4 is a 30 cm x 30 cm plastic blind ditch.

[0022] A plurality of transverse plastic blind pipes 5 are provided on the top surface 3 of the embankment. The spacing between the transverse plastic blind pipes 5 is 5-10m, and the transverse plastic blind pipes 5 are Φ100 transverse plastic blind pipes 5. Both ends of the transverse plastic blind pipes 5 are connected to the buried part of the longitudinal plastic blind ditch 4.

[0023] Several plastic blind ditches 1 are installed along the slope of the embankment's waterfront surface 2. The tops of these blind ditches 1 connect to the buried portion of the longitudinal plastic blind ditch 4, and their bottoms extend horizontally from the bottom of the embankment to a certain depth. The spacing between these blind ditches is 20 meters, and each measures 30 cm x 30 cm.

[0024] The longitudinal plastic blind ditch 4, the transverse plastic blind pipe 5 and the slope plastic blind ditch 1 are all wrapped with anti-filtration geotextiles.

[0025] During actual use, the utility model allows accumulated water on the top surface of the embankment to flow into the exposed portion of the longitudinal plastic blind ditch. Simultaneously, rainwater on the top surface of the embankment seeps into the transverse plastic blind pipes, which then flow along the slope plastic blind ditch into the river channel. This guides the flow of rainwater and prevents rainwater from scouring the top surface of the embankment and the slope surface, creating gullies. Because the longitudinal plastic blind ditch, transverse plastic blind pipes, and slope plastic blind ditch are wrapped with anti-filtration geotextiles, soil loss near the blind pipes and ditches is effectively prevented, and the extent of embankment erosion caused by heavy rain is also reduced.
