Description

Technical Field

[0001] This utility model relates to the technical field of ecological management of steep slopes, and in particular to a stepped corridor structure applied to steep slopes. Background Technology

[0002] Currently, steep slope farmland with a gradient of 15-20° or more generally faces practical problems such as fragmented terrain, concentrated rainfall, and thin and infertile soil. Existing steep slope management models have obvious shortcomings: 1. Traditional governance measures often focus on a single ecological function (such as building drainage ditches separately) or a single production need (such as laying production roads separately), failing to take into account both "soil and water conservation" and "agricultural production guarantee", resulting in the coexistence of ecological degradation and low production efficiency on steep slopes. 2. Steep slopes have poor water retention capacity, and rainwater "comes and goes away quickly," resulting in water waste. At the same time, rainwater runoff is prone to carrying away soil and fertilizer, creating a phenomenon of "water runoff, fertilizer runoff, and soil runoff," which further exacerbates the depletion of arable land. 3. Drainage ditches and production roads need to be planned and constructed separately, which not only occupies more steep slope resources, resulting in low land utilization, but also increases project costs and the difficulty of later maintenance.

[0003] In view of this, the inventors have specifically designed a stepped corridor structure for use on steep slopes, which leads to this invention. Utility Model Content

[0004] To solve the above problems, the technical solution of this utility model is as follows: A sedimentation terrace structure for use on steep slopes includes a main concrete structure, a turntable, settlement joints, and a sedimentation tank. The main concrete structure is set along the steep slope and includes, from top to bottom, concrete steps, concrete layers, and plain concrete cushion layer, and concrete side walls are provided on both sides of the main concrete structure. Multiple turntables are spaced apart along the horizontal projection direction of the concrete structure. Multiple settlement joints are spaced apart along the extension direction of the main concrete structure, and a layer of filling material is provided inside the joints. The sedimentation tanks are located at the turntables, and each turntable is equipped with one sedimentation tank.

[0005] Preferably, the concrete step, concrete layer, and plain concrete cushion layer are respectively a C25 concrete step, a 150mm thick C25 concrete layer, and a 100mm thick C15 plain concrete cushion layer.

[0006] Preferably, the main concrete structure is provided with a plurality of anti-slip tenons protruding in the direction away from the concrete steps along its extension direction.

[0007] Preferably, the turntable is installed every 5 to 10 meters along the horizontal projection direction of the main concrete structure and every 3 to 6 meters along the vertical height.

[0008] Preferably, settlement joints are set every 6m along the extension direction of the main concrete structure.

[0009] Preferably, the filling material layer is an asphalt-impregnated hemp fiber filling layer.

[0010] Preferably, the sedimentation tank includes a main body, and the main body is a frame structure with an upper opening formed by a C25 concrete layer. A crushed stone cushion layer is laid below the main body, and a grating plate is covered at the upper opening of the main body.

[0011] Preferably, the thickness of the crushed stone cushion layer is 100 mm.

[0012] Preferably, the height of the concrete sidewall is 0.5~1m.

[0013] Preferably, the grating is a galvanized steel grating.

[0014] The beneficial effects of this utility model are as follows: This utility model integrates the ecological functions of soil conservation, water storage, sedimentation, and drainage with the function of production road access through concrete steps, turntables, and sedimentation tanks. It eliminates the need to build drainage ditches and production roads separately, avoids redundant construction, and reduces project costs. In addition, it makes full use of the existing space on steep slopes without occupying additional arable land resources, which is in line with the actual application scenario of scarce land resources on steep slopes.

[0015] In addition, the C25 / C15 concrete layered design, combined with settlement joints to release stress, is suitable for complex conditions of steep slopes above 20°, and is expected to have stable operating performance. In addition, this utility model not only solves the problem of soil erosion on steep slopes and improves the ecological environment, but also facilitates the harvesting of agricultural products and the transportation of production materials, improves the convenience of agricultural production, helps increase agricultural output and rural income, and achieves a win-win situation for ecology and production. In particular, the plan is tailored to the actual needs of steep slope management, and the technical approach is mature, which can provide a reference for similar comprehensive water and soil erosion management projects on steep slope farmland.

[0016] In summary, this novel stepped corridor structure adopts a multi-functional management model, serving both as a drainage ditch and a path for sloping farmland, facilitating villagers' harvesting and transportation, maximizing land conservation and avoiding the occupation of more land.

[0023] In this embodiment, a steep slope is defined as a slope angle of 20° or more.

[0024] Specifically, the concrete step 110, concrete layer 120, and plain concrete cushion layer 130 are respectively a C25 concrete step 110, a 150mm thick C25 concrete layer 120, and a 100mm thick C15 plain concrete cushion layer 130. The plain concrete cushion layer 130 serves as the base cushion layer, the concrete layer 120 is placed on the plain concrete cushion layer 130, and the C25 concrete step 110 is poured on top of the concrete layer 120, thus forming a three-layer composite main concrete structure 100.

[0032] Preferably, the main concrete structure 100 is provided with a plurality of anti-slip tenons 400 protruding in the direction away from the concrete step 110 along its extension direction, thereby preventing the entire main concrete structure 100 from sliding sideways.

[0033] In this embodiment, the anti-slip tenon 400 is a right-angled structure and is integrally cast with the main concrete structure 100.

[0034] The beneficial effects of this utility model are as follows: This utility model integrates the ecological functions of soil conservation, water storage, sedimentation, and drainage with the function of production road access through concrete steps 110, turntable 200, and sedimentation tank 300. It eliminates the need to build drainage ditches and production roads separately, avoids redundant construction, and reduces project costs. In addition, it makes full use of the existing space on steep slopes without occupying additional arable land resources, which is in line with the actual application scenario of scarce land resources on steep slopes.
