Description

Technical Field

[0001] This utility model relates to the technical field of municipal solid waste landfills, specifically to a rainwater and sewage diversion and drainage structure for municipal solid waste landfills. Background Technology

[0002] To prevent rainwater from entering landfills and increasing leachate production, landfills implement rainwater and sewage separation measures during operation. Currently, landfills use geomembranes as the main anti-seepage material for their rainwater and sewage separation systems.

[0003] However, the currently laid geomembrane lacks drainage structure, causing rainwater to remain on the surface of the geomembrane for a long time. This makes it easy for rainwater to enter the garbage below, resulting in an increase in leachate. This will undoubtedly greatly increase the treatment burden of landfill leachate treatment stations and increase operating costs, which urgently needs to be improved. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a rainwater and sewage diversion and drainage structure for a municipal solid waste landfill, which can divert rainwater on the surface and separate it from the sewage below, so as to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a rainwater and sewage diversion and drainage structure for a municipal solid waste landfill, comprising a drainage trough welded from multiple troughs. Multiple drainage troughs are provided, each embedded in the surface of the municipal solid waste landfill. A thickened portion protrudes from the bottom surface of each drainage trough, and a fixed groove extends from the bottom surface of the inner cavity of each drainage trough into the thickened portion. An impermeable membrane is provided between each drainage trough, with both ends of the membrane extending into the fixed groove. A clamping rod, welded from multiple pressure rods, is provided in each fixed groove, and both ends of the impermeable membrane are pressed into the fixed groove by the clamping rod.

[0006] As a preferred technical solution, excluding the outermost clamping rod, the cross-sections of the remaining clamping rods are all trapezoidal, the cross-sections of the fixing grooves are all trapezoidal, the opposite sides of the clamping rods on both sides protrude to form sealing parts, and the gaps between the outer sides of the clamping rods on both sides and the fixing grooves are sealed by the sealing parts.

[0007] As a preferred technical solution, the clamping rod is provided with multiple first screw holes, and the thickened part is provided with second screw holes at the positions corresponding to the first screw holes. The corresponding first screw holes and second screw holes are threaded with fixing bolts for locking the clamping rod.

[0008] As a preferred technical solution, the middle of the geomembrane is arched by garbage, and the two ends of the geomembrane near the drainage channel are bent downwards.

[0009] As a preferred technical solution, drainage pipes are installed at both ends of the drainage channel.

[0010] As a preferred technical solution, multiple insertion rods are installed on the thickened part.

[0011] As a preferred technical solution, the cross-section of the drainage channel is set in a trapezoidal structure.

[0012] The beneficial effects of this utility model are: the utility model has a simple structure, the drainage ditch is pressed down on the surface of the landfill, and the two ends of the geomembrane are directly fixed in the drainage ditch and arched. The geomembrane can be quickly disassembled, which facilitates subsequent replacement. Rainwater on the surface of the geomembrane can flow into the drainage ditch for unified extraction, reducing the probability of seeping into the interior of the landfill. It can be separated from the leachate inside as much as possible, reducing the burden on the treatment station. Attached Figure Description

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0021] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a rainwater and sewage diversion and drainage structure for a municipal solid waste landfill, comprising a drainage trough 1 welded from multiple troughs. Multiple drainage troughs 1 are provided, each embedded in the surface of the municipal solid waste landfill. A thickened portion 7 protrudes from the bottom surface of each drainage trough 1, and a fixing groove 8 extends from the bottom surface of the inner cavity of each drainage trough 1 into the thickened portion 7. An impermeable membrane 2 is provided between each drainage trough 1, with both ends of the impermeable membrane 2 extending into the fixing groove 8. A clamping rod 3, formed by welding multiple pressure rods, is provided in each fixing groove 8, and both ends of the impermeable membrane 2 are pressed tightly into the fixing groove 8 by the clamping rod 3.

[0023] In this embodiment, except for the outermost clamping rod 3, the cross-sections of the remaining clamping rods 3 are all trapezoidal, and the cross-sections of the fixing grooves 8 are all trapezoidal. The opposite sides of the clamping rods 3 on both sides protrude to form sealing parts 9, and the gaps between the outer sides of the clamping rods 3 on both sides and the fixing grooves 8 are sealed by the sealing parts 9. The sealing parts can seal the gaps between the clamping rods on both sides and the fixing grooves, thereby preventing rainwater from entering the fixing grooves.

[0024] In this embodiment, the clamping rod 3 is provided with a plurality of first screw holes, and the thickened part 7 is provided with a second screw hole at the position opposite to the first screw hole. The corresponding first screw hole and second screw hole are threaded with a fixing bolt 4 for locking the clamping rod 3.

[0025] In this embodiment, the middle of the geomembrane 2 is arched by garbage, and the two ends of the geomembrane 2 near the drainage trough 1 are bent downwards so that the rainwater on the surface can flow quickly to both sides along the arched surface and enter the drainage trough.

[0026] In this embodiment, drain pipes 5 are installed at both ends of the drainage trough 1; multiple insertion rods 6 are installed on the thickened part 7.

[0027] In this embodiment, the cross-section of the drainage trough 1 is set in a trapezoidal structure, so that the incoming rainwater can gather in the middle and be discharged uniformly along the drainage pipe.

[0028] Working principle: The drainage channel can be pressed down and embedded into the surface of the landfill, while the insertion rod can be inserted into the interior of the landfill, increasing the stability after installation; the two ends of the geomembrane can extend into the fixing groove, and the clamping rod can be placed into the fixing groove, and the fixing bolts are threaded into the corresponding first screw hole and second screw hole. The fixing bolts can press down the clamping rod, and the lowered clamping rod can fix the two ends of the geomembrane in the drainage channel without the need for heat fusion fixing. Afterwards, the geomembrane can be replaced after the fixing bolts are removed.

[0029] During geomembrane installation, more debris can accumulate in the middle of the geomembrane, while less accumulates on the sides. This causes the geomembrane to arch in the middle and bend downwards on the sides. After rain, rainwater can quickly flow along the surface of the geomembrane into the drainage channel. Flexible hoses can be connected to the drainage pipes at both ends of the drainage channel, and one end of the hose can be connected to a water pump to quickly extract the surface rainwater, greatly reducing the probability of residue and seepage.

[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
