The design of flood drainage ditch should be closely coordinated with the overall planning of water conservancy, make full use of the original mountain torrent ditch and carry out appropriate repair, in order to use natural terrain slope to optimize the drainage effect. In addition, the flood drainage ditch also plays an important role in agricultural irrigation, which can transport water through drainage, save manpower and material resources, and avoid erosion of fertilizers on the ditch body. The flood drainage ditch plays a key role in flood prevention, which can effectively dredge flood, reduce disaster impact.

[0003] In the reservoir construction, considering the possible flood peak in the high water period and the water quantity influence of mountain torrent, the part of river near the reservoir in the downstream usually sets the flood drainage ditch near the bank of mountain.

This may lead to further collapse of mountain, resulting in a large amount of soil and stone entering the flood drainage ditch, which may completely block the flood drainage ditch in serious cases, affecting the guidance and discharge of flood, and threatening the life safety of people in the downstream.

DETAILED DESCRIPTION

[0018] The technical solutions of the utility model will be further described below in combination with the drawings and embodiments.

[0019] As shown in the drawings, the utility model embodiment proposes a landslide-resistant flood drainage ditch structure, which comprises a mountain retaining wall 1 arranged on one side of a mountain, a waterproof retaining wall 2 arranged on one side of a river channel, and a ditch body 3 located between the mountain retaining wall 1 and the waterproof retaining wall 2. Figure 1

[0020] ​Specifically, the retaining wall 1 includes a biological stabilization layer 4 and a gravel cushion layer 5 arranged sequentially from top to bottom. The biological stabilization layer 4 is usually a grass layer, which combines with the gravel cushion layer 5 through the growth of grass roots to form a more stable integrated structure. Correspondingly, a layer of sand is laid on top of the gravel cushion layer 5 for plant growth. Preferably, a fixing net is also provided on the surface of the biological stabilization layer 4 to maintain the strength of the surface of the biological stabilization layer 4 before the grass seeds are fully grown, preventing the grass seeds or newly grown seedlings from being washed away by rainwater and detached from the slope.

[0021] In this embodiment, the retaining wall 1 further includes a self-stabilizing layer 6. The self-stabilizing layer 6 includes pressure-bearing members 61 connected in sequence. The pressure-bearing members 61 have an arc-shaped surface structure with their axial direction parallel to the extension direction of the drainage ditch. They are connected in sequence through opposite sides of the arc-shaped surface to form a strip-shaped support chain arranged from top to bottom along the direction of the retaining wall 1. Adjacent support chains are stacked in layers through the corresponding axial ends of the pressure-bearing members 61, similar to the way roof tiles cover the eaves, forming a fully covered self-stabilizing layer 6. The two ends of the pressure-bearing members 61 corresponding to the arc-shaped surface penetrate the biological stabilizing layer 4 and the gravel cushion layer 5, respectively, and extend into the interior of the mountain below.

[0022] In a further embodiment, the radial cross-section of the pressure-bearing component 61 has an arc of 180°-270°. This embodiment uses a 270° arc, so adjacent pressure-bearing components 61 are connected by outwardly convex arc-shaped surfaces, which can be achieved through rope connections, concrete connections, or other methods. This sequential connection facilitates construction and transportation. Once the end of the pressure-bearing component 61 extends into the mountainside, a natural support chain structure is formed, eliminating the need for additional connections between the pressure-bearing components 61.

[0023] like Figure 2 As shown in this preferred embodiment, the end of the pressure-bearing component 61 located inside the mountain is further provided with a connecting rod 62, which extends inward perpendicular to the mountain slope. Furthermore, the end of the connecting rod 62 near the inside of the mountain is also provided with a forked head 63, which includes several branching tie rods, each of which is inclined and not parallel to the mountain slope, and the tie rods are fixedly connected to the connecting rod 62. Therefore, when the pressure-bearing component 61 is subjected to force, the connecting rod 62 pushes the tie rods towards the inside of the mountain, forming a complex, interwoven mesh structure. This not only strengthens the structural strength inside the mountain but also enhances the connection strength between the pressure-bearing component 61 and the mountain, making the self-stability of the pressure-bearing component 61 more prominent.

[0024] like Figure 3As shown, the pressure bearing part 61 comprises an elastic layer 611 and a hard layer 612 arranged from outside to inside, wherein the hard layer 612 is a reinforced concrete structure. The elastic layer 611 can adopt a rubber layer, thereby reducing the impact force of earth and stone on the surface of the pressure bearing part 61 and placing the pressure bearing part 61 from breaking. As preferred, the hard layer 612 is further provided with a steel reinforcement mesh 613 inside and parallel to the arc-shaped side surface of the pressure bearing part 61. The strength of the pressure bearing part 61 is further improved through the steel reinforcement mesh 613, so that the pressure bearing part 61 will not be completely broken after being deformed by excessive pressure and still maintains a certain connectivity, which can play a partial supporting capacity.

[0025] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and not to limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the present application, and all of them should be covered in the scope of the claims of the present application.
