Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drainage, in particular to a slope diversion, hedging and energy dissipation drainage structure and system. Background Art
[0002] In recent years, high-fill airports are very common in my country, with fill heights reaching tens or even hundreds of meters. However, the drainage ditches and slopes of high-fill airports are often destroyed, which seriously affects the normal use of the airport. The reason for this is largely due to the unreasonable design of the airport slope drainage, which causes a large water flow speed, eventually eroding the drainage ditch or rushing out of the drainage ditch, causing damage, and finally causing the slope to be destroyed.
[0003] In order to reduce the water flow velocity on the slope, the invention patent with application number 202110830216.0 discloses a "slope drainage structure and method", which has several embedded blocks on the slope, and several embedded blocks are respectively provided with water stop plates, and the water stop plates are provided with several water stop holes, and the water stop plates are also provided with several first filter cloths for closing the water stop holes. The above structure reduces the loss of soil on the slope surface during the slope drainage process, but its structure is complex, and the setting of the water stop plate structure will have a certain impact on the drainage capacity, which will affect the drainage capacity when used in areas with large water flow. Utility Model Content
[0004] The purpose of the utility model is to overcome the shortcomings of the existing slope drainage structure, such as complex structure and poor drainage capacity when the water flow rate is large, and to provide a slope diversion and hedging energy dissipation drainage structure and system, which has a simple structure and maintains drainage capacity when draining large flows, greatly dissipates water energy, reduces water flow velocity, and improves slope safety.
[0005] The purpose of the utility model is achieved through the following technical solutions:

[0009] A central energy dissipation groove is arranged between the diffusion energy dissipation groove and the contraction energy dissipation groove and is connected through the energy dissipation hole.
[0010] The second aspect of the utility model discloses an airport slope diversion hedging energy dissipation drainage system, comprising an upstream slope section drainage ditch and a downstream outlet section drainage ditch, between which a slope diversion hedging energy dissipation drainage structure as described in the first aspect is arranged.
[0011] The utility model has the following advantages:
[0012] The utility model arranges diffusion energy dissipation ditches and contraction energy dissipation ditches on both sides of the central energy dissipation ditch. The diffusion energy dissipation ditches and the contraction energy dissipation ditches constitute counter-energy dissipation ditches, which greatly reduce the water flow velocity in the slope drainage ditch, reduce scouring, and make the slope drainage ditch drain smoothly, thereby ensuring the safety of the slope.

[0023] The first aspect of the utility model discloses a slope diversion and hedging energy dissipation drainage structure, which can be applied not only to airport slopes, but also to slopes in other environments to achieve drainage, such as schools, hillsides, etc. Specifically, the drainage structure includes a diffusion energy dissipation ditch, a contraction energy dissipation ditch and a central energy dissipation ditch 8. Figure 1 , 2 As shown, the diffusion energy dissipation ditch 5 and the contraction energy dissipation ditch 6 each have two sections.

The energy dissipation holes 9 are evenly arranged on all sides of the central energy dissipation area 8, and can be in the form of strip holes, round holes, etc. Figure 3 The figure shown is a schematic diagram of a structure using strip holes.
[0032] The second aspect of the utility model discloses a slope diversion and hedging energy dissipation drainage system, such as Figure 4 As shown, it includes an upstream slope section drainage ditch and a downstream outlet section drainage ditch, and a slope diversion, hedging and energy dissipation drainage structure described in the first aspect is arranged between the upstream slope section drainage ditch and the downstream outlet section drainage ditch.
[0033] The drainage ditch in the upstream slope section is set on the slope in an inclined shape; the drainage ditch in the downstream outlet section is horizontal.
