Description

Technical Field

[0001] The utility model relates to the technical field of coal gangue mountain restoration, in particular to a grass planting device for restoration and management of abandoned coal gangue mountain. Background Art

[0002] Gangue is a solid waste discharged during the coal production process, accounting for 15% to 20% of the raw coal output. Spontaneous combustion, explosion, landslide and leaching water of gangue heaps all pollute the mining environment. It is necessary to plant grass and repair the abandoned gangue heaps.

[0003] The utility model with the publication number CN208446248U discloses a drought-resistant grass planting device, including a grass planting blanket, side guard plates are arranged around the grass planting blanket, connecting blocks are fixed between the side guard plates, and anchor holes are arranged on the connecting blocks. The side guard plates also include a bottom plate, and two side plates are symmetrically fixed to the upper end of the bottom plate. A vertical plate and a windproof plate are arranged between the two side plates. The vertical plate is next to the grass planting blanket and fixed to the bottom plate. A water storage cavity is arranged inside the vertical plate. The vertical plate is provided with multiple rows of water discharge holes on the side facing the grass planting blanket, and each row is provided with a plurality of water outlet holes, and the water outlet holes are connected with the water storage cavity.

[0004] The above technical solution prevents the evaporation of ground water by laying grass carpets and keeps the soil under the grass carpets moist, thereby ensuring the water required by plants. The windbreaks can effectively prevent wind and drought and reduce the rapid loss of water caused by wind. The inclination of the windbreaks makes the wind blow obliquely upward, which has a certain guiding effect, reduces wind resistance, and makes the side guard plates more stable. The contraction of the springs plays a shock-absorbing role, which reduces the shaking of the side guard plates, thereby ensuring the healthy growth of plants. The water storage cavity of the vertical plate can accumulate rainwater, and the stored water flows into the grass carpet through the water outlet holes for irrigation, thereby saving water resources. In order to alleviate the drought, multiple rows of water discharge holes are provided, and each row is provided with several water outlet holes. Water is released row by row to control the water volume. The dustproof net prevents foreign matter from entering the water storage chamber. The anchors can be nailed into the ground through the anchor holes on the connecting blocks to enhance stability. However, when the abandoned coal gangue mountain is repaired and managed to be planted with grass, the poor geology of the coal gangue mountain is not conducive to the stable growth of grass. There is no stable water storage and water supply coordination on the ground of the coal gangue mountain, and the fragments of the coal gangue mountain are not conducive to the rooting of grass, and the movement of the fragments will damage the grass, which is not convenient for stable grass planting and reduces the damage of the fragments to the grass stems.
