Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of mine drainage, specifically relates to a mine dump slope water guide device. BACKGROUND

[0002] The mine dump is mostly soil slope, under the condition of heavy rainfall in the rainy season, the top surface of the dump step slope often forms a catchment area, and a large amount of accumulated rainwater will flow down along the slope, and long-term erosion will lead to slope instability and seriously affect the platform strength. Therefore, measures such as interception, diversion and drainage must be taken to prevent the softening of the slope soil and further cause landslides and other geological disasters.

[0003] In order to quickly collect and drain the rainwater in the catchment area outside the slope, the commonly used solution is to arrange a water collecting ditch and a drainage ditch in the slope body, wherein the water collecting ditch transverses the slope, the drainage ditch longitudinally drains along the slope, and the two are crisscrossed to form a drainage ditch network. The problems of the drainage ditch network are: (1) in order to quickly drain the catchment out of the slope, the drainage ditch needs to use a steep slope, but under the condition of heavy rain, the torrent in the drainage ditch will flow down along the steep slope, and it is easy to overflow outside the ditch at the turning point, which cannot prevent the catchment from eroding the slope; (2) the water collecting ditch and the drainage ditch are often built with mortar rubble or concrete, and a sinking joint needs to be set every certain distance, and the surface needs to be jointed, and the broken part needs to be repaired in time after jointing, which has complex construction process and difficult maintenance.

[0004] In summary, a slope water guide device suitable for mine dump is proposed to overcome the above-mentioned deficiencies. CONTENT OF THE UTILITY MODEL
