Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy engineering, and in particular relates to a rapid greening structure suitable for plateau slag piles. Background Art

[0002] Water conservancy and hydropower projects generally require the establishment of slag dumps. During the construction of slag dumps, the surrounding natural environment will be greatly damaged. The environment of the southwestern plateau is very fragile, so it is necessary to restore vegetation and conserve soil and water in the damaged areas in a timely and rapid manner. Slag dumps are often lumps of stone and slag, which have little soil content and poor water retention.

[0003] For the above-mentioned slag pile located in the southwestern plateau area, when the slag pile is also located by the river, it is necessary to carry out slope foot protection and greening treatment on the slag pile, and the greening measures are located on the slag pile and the slope foot protection, while taking into account the requirements for local species protection. The greening measures need to be combined with the water retention of the slag pile, the moisture retention and freezing depth of the planting soil, the matching of the selected vegetation species and the region, and the location of the slag pile by the river.

[0004] Common greening measures on slag bodies and slope foot protection structures in the prior art include cast-in-place concrete planting troughs covered with soil for greening, finished planting troughs covered with soil for greening, and laying transition cushion materials for covering soil for greening. The cast-in-place reinforced concrete planting trough greening scheme uses cast-in-place concrete, which requires a large number of templates and a certain maintenance period, resulting in a long construction period for the greening project and high overall cost; the finished planting trough covered with soil for greening scheme has high procurement and transportation costs and a long time in the southwestern plateau area, and is placed on irregular terrain such as slag bodies, so it has poor adaptability and durability; the construction process requirements of laying transition cushion materials for covering soil for greening are high, and the requirements for the gradation and thickness of the covering soil are high. It is easy to cause the loss of covering soil due to poor on-site gradation control and construction quality problems, resulting in poor greening effect. In addition, planting soil is scarce in the southwestern plateau area, and this scheme requires a large amount of covering soil. Utility Model Content
