Description

Technical Field

[0001] This utility model relates to the field of civil engineering, and in particular to an earth-rock dam structure for a landfill. Background Technology

[0002] Earth-rock dams in landfills are structures used to enclose and stabilize landfill areas. These dams are mainly constructed from surrounding natural materials such as soil and rock, and are designed to prevent leachate leakage and control the emission of landfill gases, while also helping to maintain the overall stability of the landfill.

[0003] Traditional earth-rock dams in landfills are usually constructed by compaction. However, the outer side of earth-rock dams is easily eroded by rainwater, leading to soil erosion. Therefore, slope protection is usually built to protect the stability of earth-rock dams. However, the construction of slope protection increases the construction period and affects the construction efficiency of earth-rock dams, which needs to be improved. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an earth-rock dam structure for landfills, which has the effect of improving construction efficiency.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an earth-rock dam structure for a landfill, comprising:

[0006] The dam body has a trapezoidal cross-section.

[0007] The protective slope is set in a stepped manner on the outside of the dam body;

[0008] The protective slope includes a prefabricated frame and planting bags. The prefabricated frames are arranged side by side and layered in a stepped manner. The planting bags are placed inside the prefabricated frames.

[0009] In a preferred embodiment, the present invention can be further configured such that: one end of the prefabricated frame is vertically provided with a card strip, and the other side is provided with a card slot for the card strip to be embedded.

[0010] In a preferred embodiment, the present invention can be further configured such that: a positioning block is provided on the lower end face of the front end of the prefabricated frame, and a positioning hole for the positioning block to be embedded is provided at the middle position of the upper end face.

[0011] In a preferred embodiment, the present invention can be further configured such that: the lower end face of the tail end of the prefabricated frame is provided with a needle that can penetrate into the dam body.

[0012] In a preferred embodiment, the present invention can be further configured such that a zipper is provided at the opening of the planting bag.

[0013] In a preferred embodiment, the present invention can be further configured such that an impermeable membrane is laid on the inner side of the dam body.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. By setting up a modular protective slope structure, the protective slope can be quickly assembled after the dam body is compacted, which improves construction efficiency. At the same time, the protective slope is composed of prefabricated frames and planting bags, which can not only protect the dam body, but also grow grass and form an ecological slope structure, which can improve the aesthetics and prevent soil erosion.

[0016] 2. By setting interlocking structures between prefabricated frames, the stability of the prefabricated frames after assembly is increased, ensuring the protective performance of the slope. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 As shown, an earth-rock dam structure for a landfill includes a dam body 1 and a protective slope 2.

[0022] like Figure 1 As shown, the cross-section of dam body 1 is trapezoidal. An impermeable membrane 3 is laid on the inner side of dam body 1 to prevent the leakage of internal leachate and to limit the infiltration of external rainwater. The protective slope 2 is set in a stepped shape on the outer side of dam body 1 to prevent soil erosion of dam body 1.

[0023] like Figure 1 , Figure 2 As shown, the protective slope 2 includes a prefabricated frame 21 and planting bags 22. The prefabricated frame 21 is rectangular and has six open sides. The prefabricated frames 21 are arranged side by side and layered in a stepped manner. The planting bags 22 are placed inside the prefabricated frame 21. The opening of the planting bags 22 is equipped with a zipper 23 to facilitate filling with soil and grass seeds.

[0024] Therefore, by setting up a modular protective slope 2 structure, the protective slope 2 can be quickly assembled and constructed after the dam body 1 is compacted, thus improving construction efficiency. At the same time, the protective slope 2 is composed of prefabricated frame 21 and planting bags 22, which can not only protect the dam body 1, but also grow grass plants to form an ecological slope protection structure, which can improve aesthetics and prevent soil erosion.

[0025] like Figure 2 As shown, a clip 24 is vertically provided at one end of the prefabricated frame 21, and a slot 25 for the clip 24 to be inserted is provided on the other side, so as to increase the stability and structural strength between two adjacent prefabricated frames 21.

[0026] like Figure 2 As shown, a positioning block 26 is provided on the lower end face of the front end of the prefabricated frame 21, and a positioning hole 27 for the positioning block 26 to be embedded is provided in the middle of the upper end face, so as to increase the stability and structural strength between the upper and lower prefabricated frames 21.

[0027] like Figure 2 As shown, the lower end face of the precast frame 21 is provided with a needle 28 that penetrates into the dam body 1. Therefore, during the construction of the precast frame 21, the needle 28 on the precast frame 21 penetrates into the dam body 1 to increase the stability between the precast frame 21 and the dam body 1 and improve the structural strength between the two.
