Abstract
Description
Technical Field
[0001] This utility model relates to the field of gully erosion control technology, and in particular to a stepped straw mill for controlling gullies. Background Technology
[0002] With global climate change, soil erosion is becoming increasingly serious, especially in areas with concentrated rainfall and large topographic relief, where erosion gullies are formed. These gullies cut through arable land, weakening soil fertility, eroding the topsoil, thinning the soil layer, and thus reducing the productivity of arable land.
[0003] Methods for controlling gully erosion include vegetation restoration and engineering measures. However, these methods often suffer from high costs and unstable results. In addition, vegetation restoration takes a long time and has certain limitations. In recent years, natural materials such as straw and stones have been used to construct ecological protection structures to curb the formation of gullies. Therefore, we need a stepped straw mill for controlling gullies. Utility Model Content

[0005] This utility model also provides a stepped straw mill for controlling erosion gullies, comprising: a dam body, a stepped frame body above the dam body, a ladder protection unit on the upper end of the stepped frame body, and a reinforcing unit on the upper end of the ladder protection unit.
[0006] The stepped frame is composed of multiple hollow cages stacked one after another, and the inner walls of the multiple hollow cages are filled with gravel and straw.
[0007] According to the stepped straw mill for controlling erosion gullies, the ladder protection unit includes a ladder protection frame laid on the upper surface of the stepped frame, the inner wall of the ladder protection frame is equipped with ground binding net, and a support frame is fixedly connected to the inner wall of the ladder protection frame and at the lower end of the ground binding net.
[0008] According to the stepped straw mill for controlling erosion gullies, there are two support frames, and the two support frames are arranged in a cross pattern.
[0009] According to the stepped straw mill for controlling erosion gullies, the reinforcing unit includes reinforcing rib one and reinforcing rib two, which are arranged in a cross pattern. Reinforcing rib one is vertically inserted through the ladder frame and into the dam body, while reinforcing rib two is arranged horizontally inside the dam body.
[0010] According to the aforementioned stepped straw dam for controlling erosion gullies, one side of the dam body is a sloping surface, the dam body is composed of flood control stones and gravel, and the bottom of the dam body is a reinforced concrete structure.
[0011] This utility model has the following beneficial effects:
[0012] 1. In this utility model, the dam body, stepped frame, ladder protection unit and reinforcement unit are used to effectively manage the erosion gully. At the same time, the structure not only has good stability and durability, but also promotes vegetation restoration and soil retention. In addition, it saves management costs and shortens the management cycle.

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0021] Reference Figure 1-3This utility model embodiment provides a stepped straw mill for controlling erosion gullies, which includes: a dam body 1, a stepped frame 2 above the dam body 1, a ladder protection unit 3 on the upper end of the stepped frame 2, and a reinforcing unit 4 on the upper end of the ladder protection unit 3.
[0022] The stepped frame 2 is composed of multiple hollow cages 201 stacked sequentially, with the inner walls of the hollow cages 201 filled with crushed stones 202 and straw blocks 203. The stepped frame 2 can prevent water erosion.
[0023] The ladder protection unit 3 includes a ladder protection frame 301 laid on the upper surface of the stepped frame 2. The inner walls of the ladder protection frame 301 are all fitted with ground-binding netting 302. A support frame 303 is fixedly connected to the inner wall of the ladder protection frame 301 at the lower end of the ground-binding netting 302. The ladder protection unit 3 can fix the gravel 202 and straw stalks 203, preventing soil erosion.
[0024] There are two support frames 303, and the two support frames 303 are arranged in a cross pattern. The support frames 303 enhance the structural strength of the ladder guard frame 301.
[0025] The reinforcing unit 4 includes reinforcing rib 1 401 and reinforcing rib 2 402, which are arranged crosswise. Reinforcing rib 1 401 is vertically inserted through the ladder frame 301 and into the dam body 1, while reinforcing rib 2 402 is arranged laterally inside the dam body 1. The reinforcing unit 4 improves the stability between the dam body 1 and the ladder frame 301, and also enhances the structural strength of the dam body 1.
[0026] One side of dam body 1 is a sloping surface. Dam body 1 is composed of flood control stones and crushed stone, and the bottom of dam body 1 is a reinforced concrete structure. Dam body 1 reduces the impact of water flow and soil erosion.
[0027] Working principle: During use, the dam body 1 enhances the stability of the overall structure, slows down the water flow velocity, and reduces the erosion of the soil by the water flow. Multiple hollow cages 201, as well as crushed stones 202 and straw blocks 203, further enhance the stability of the overall structure and improve soil retention. In addition, the straw blocks 203 can increase soil organic matter and promote plant growth during the decomposition process. The ladder frame 301, ground binding net 302, and support frame 303 can effectively prevent soil erosion and improve the structure, making it better able to resist the erosive force of water flow. The cross-set reinforcing ribs 1 401 and 2 402 further improve the load-bearing capacity and durability of the entire structure, strengthen the stability between the dam body 1 and the ladder unit 3, and enhance the overall stability of the dam body 1.
[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
