Slope drainage structure of waste dump

Abstract

The present invention discloses a slope drainage structure for a waste dump, wherein an inclined slope drainage ditch is arranged on the outer slope between the upper and lower horseway platforms of the waste dump, the starting point of the slope drainage ditch is located at the lower slope of one end of the upper horseway platform, the end point is located at the inner side of the lower horseway platform at the far end and is connected to the intercepting ditch, and the rainwater collected in the slope drainage ditch is introduced into the intercepting ditch. Since the intersection angle between the slope drainage ditch and the intercepting ditch is large, the water flow in the slope drainage ditch cannot be smoothly introduced into the intercepting ditch. In order to prevent the impact of the water flow, a cover plate is cast at the connection between the slope drainage ditch and the intercepting ditch. The present invention increases the longitudinal slope of the slope drainage ditch, effectively solves the problem that the drainage ditch of the horseway platform is easily blocked by siltation, and ensures the effective drainage of the slope of the waste dump.

Description

Technical Field

[0001] The invention relates to the technical field of waste dumps, in particular to a slope drainage structure for a waste dump. Background Art

[0002] The slope drainage ditch of the waste dump is generally set on the horseway platform, and connected to the intercepting ditch on both sides. Since the slope drainage ditch set on the horseway platform has a small slope, it is easy to be blocked by debris during the later operation, affecting the drainage capacity, and even the slope drainage ditch of the waste dump is completely silted up, and the drainage function is completely ineffective. Rainwater rushes from the top of the slope along the slope to the downstream, and the slope is washed by rainwater, forming surface erosion and gully erosion, and even threatening the stability of the slope of the waste dump. In order to ensure the normal drainage of the slope drainage ditch, it is necessary to frequently desilt, which invisibly increases the management cost.

[0003] Therefore, how to reasonably solve the problem of slope drainage of waste dumps, ensure the drainage effect of the slope of waste dumps, and facilitate management at the same time is an issue that needs to be solved urgently. Summary of the invention

[0006] The height difference between the upper and lower horseway platforms is between 5 and 10 meters.

[0007] The slope drainage ditch adopts a concrete structure with a net cross-sectional size of 0.4m in width × 0.5m in depth and a wall thickness of 0.15m to 0.2m.

[0008] The intercepting ditch adopts a concrete structure with a net cross-sectional dimension of 0.8m in width x 1.0m in depth and a wall thickness of 0.2m to 0.25m.

[0009] The upstream and downstream of the intercepting ditch are respectively provided with a 2-3m long cover plate section, and the slope drainage ditch is also provided with a 2-3m long cover plate section.

[0010] The cover plate adopts a prefabricated concrete structure, the thickness of the cover plate is not less than 0.1m, and the gaps between the cover plates are filled with cement mortar.

[0011] The beneficial effects of the present invention are: simple structure, easy management, capable of preventing the drainage ditch on the slope of the waste dump from being blocked by debris, ensuring the drainage effect of the drainage ditch, and saving management costs in the later operation process.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0017] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] like Figure 1-3As shown, the slope drainage structure of the waste dump of the present invention is provided with an inclined slope drainage ditch 2 on the outer slope between the upper and lower horseway platforms 1. The starting point of the slope drainage ditch 2 is located on the slope below the upper horseway platform, and the end point is located on the inner side of the lower horseway platform 1, and is connected to the intercepting ditch 3. The rainwater collected in the slope drainage ditch 2 is introduced into the intercepting ditch 3. Since the intersection angle between the slope drainage ditch 2 and the intercepting ditch 3 is large, the water flow in the slope drainage ditch 2 cannot be smoothly introduced into the intercepting ditch 3. In order to prevent the impact of water flow, a cover plate 4 is cast at the connection between the slope drainage ditch 2 and the intercepting ditch 3.

[0019] The height difference between the upper and lower horseway platforms 1 is between 5m and 10m.

[0020] The slope drainage ditch 2 adopts a concrete structure. In practical applications, the water flow section size can be determined according to the amount of water collected on the slope. In a preferred embodiment, the net section size L1 is 0.4m, H1 is 0.5m, and the wall thickness A1 is 0.15m to 0.2m.

[0021] The intercepting ditch 3 adopts a concrete structure. In practical applications, the water-passing section size can be determined according to the amount of water collected by the surrounding mountains and slopes. In a preferred embodiment, the net section size L2 is 0.8m, H2 is 1.0m, and the wall thickness A2 is 0.2m to 0.25m.

[0022] The cover plate 4 is a prefabricated concrete structure. In a preferred embodiment, the thickness h of the cover plate is 0.1 m, and the gaps between the cover plates 4 are filled with cement mortar.

[0023] In the embodiment, the slope drainage ditch 2 has a certain slope, which can effectively prevent clogging by debris and can quickly guide the rainwater collected on the slope into the intercepting ditch 3. The cover plate 4 is a concrete structure that can withstand the impact of the water flow collected by the slope drainage ditch 2, which can effectively solve the slope drainage problem of the waste dump. It is simple to operate and easy to manage, and can save management costs in the later operation process.

[0024] The following is a detailed description. In this embodiment, first, an intercepting ditch is constructed, and waste slag is piled according to the production situation. After the two horseway platforms are formed by the pile, an inclined groove is excavated on the slope of the waste slag body and a slope drainage ditch is poured. The lower end of the slope drainage ditch is connected and communicated with the intercepting ditch. Finally, a prefabricated cover plate is placed at the connection between the slope drainage ditch and the intercepting ditch. The gap between the cover plates is filled with cement mortar, and the construction of this slope drainage ditch is completed.

[0025] The embodiments described above are only used to illustrate the technical ideas and features of the present invention, and their purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly. The patent scope of the present invention cannot be limited only by this embodiment, that is, any equivalent changes or modifications made to the spirit disclosed by the present invention still fall within the patent scope of the present invention.
