Slope greening system of novel soil layer structure and construction method of slope greening system

Abstract

The invention provides a slope greening system of a novel soil layer structure. The slope greening system comprises a slope, a riding track, a soil layer, a water storage irrigation system, a water collection open channel and a solar control system, wherein the soil layer covers the slope surface of the slope; the soil layer is composed of a mixed sandy soil layer and a clay layer in sequence frominside to outside; the water storage irrigation system comprises a water storage pipe, a water conveying pipe and a water pump; the water conveying pipe is horizontally arranged at the highest position of the mixed sandy soil layer; water seepage holes are evenly formed in the water conveying pipe; the water collection open channel comprises a rainwater confluence open channel body formed in theriding track; an opening in the bottom of the rainwater confluence open channel body communicates with the mixed sandy soil layer; and the solar control system comprises a solar power generation panel, a controller and a humidity sensor which are arranged on the riding track. The structure is simple and reasonable, construction operation is facilitated, rapid infiltration and utilization of rainwater are facilitated while the excellent slope greening capacity is achieved, the maintenance cost is saved, and water resources are saved.

Description

technical field [0001] The invention belongs to the technical field of slope greening, and in particular relates to a slope greening system with a novel soil layer structure and a construction method thereof. Background technique [0002] With the rapid development of economy and society, China's infrastructure construction has accelerated, and a large number of exposed slopes have been formed due to the implementation of construction projects such as transportation, water conservancy, mining, and electric power. The slope requires necessary engineering protection, and at the same time, people hope to restore the original vegetation as much as possible. This dual need gave birth to a new discipline - slope protection and greening. At present, its technologies are mainly divided into three categories: ① vegetation concrete slope protection and greening engineering technology; ② rock slope vegetation substrate ecological protection technology; ③ grass planting plastic soil-fi...

Problems solved by technology

However, the inherent characteristics such as steep slope and poor water retention make it difficult to grow and maintain plants. The growth of plants is uneven, and the cost of supporting irrigation and maintenance is high. Especially in the northwest region, which is dry and rainless, the survival rate of green plants on slopes is not high.

[0003] At present, the main problem encountered in slope greening across the country is that in high slope greening, there is no effective water source nearby, the irrigation head is large, and the slope is high and steep, and most of the irrigation water forms slope runoff and collects on the slope. feet, it is difficult to infiltrate into the soil in time, resulting in drought at the top of the slope, waterlogging at the bottom of the slope, and even scouring damage on the slope

At the same time, due to the inherent characteristics of the slope, it is difficult to use rainwater. Most of the rainwater flows into the road drainage system after runoff on the slope surface, and the rainfall has little effect on the irrigation of the slope.

Aiming at high slope irrigation and corresponding ecological environment problems in arid areas, there are few articles or patents to discuss and solve them. The more common solution is artificial sprinkler irrigation, which consumes a lot of water, and because of the poor water retention of slopes, most of the irrigation water is still passed through. The form of slope runoff is discharged into the road drainage system, and the utilization rate of water source is low

The method of spraying grass seeds is used for grass planting. This method has high grass planting efficiency, but the growth environment of grass seeds in the western arid region is harsh, and the evaporation on the slope is large and the water retention on the slope is poor. It is difficult for the grass seeds to survive for a long time.
