Underground intelligent drip irrigation system for ecological remediation on high and steep slope and control method

Abstract

The invention relates to an intelligent drip irrigation system for ecological remediation on a high and steep slope and a control method. The intelligent drip irrigation system is buried in an ecological slope protection base material of the surface layer of a slope body, and consists of three parts, i.e., a water delivery system, a monitoring system and a processing system, wherein a main pipe and branch pipes of the water delivery system divide the slop into a plurality of areas, the main pipe is externally connected with a water source, a capillary network communicated with the branch pipes is laid in each area, water outlet round holes are reserved in the capillary networks, and the water delivery system also has an effect of reinforcing the ecological slope protection base material; the monitoring system monitors and collects a soil humidity condition in real time by using a soil humidity sensor, and transmits the soil humidity condition to the processing system; the processing system judges whether drip irrigation needs to be performed on one area by a mathematical algorithm, and a solenoid valve connecting the corresponding capillary network and branch pipe is automatically opened when drip irrigation is needed, and is automatically closed when drip irrigation is not needed. By adopting the intelligent drip irrigation system and the control method, drip irrigation is performed without missing dead corners, human input is not needed, and the intelligent degree and the water source utilization degree are very high.

Description

technical field [0001] The invention relates to the field of slope ecological restoration and water-saving irrigation, in particular to an underground intelligent drip irrigation system and a control method for high and steep slope ecological restoration. Background technique [0002] For the ecological restoration of high and steep slopes, ecological slope protection substrates are often sprayed on the surface of the slope to create a suitable vegetation habitat. In order to strengthen the stability of the ecological slope protection base material on the slope, it is generally necessary to lay a reinforcement layer within the ecological slope protection base material at a distance of 5-6 cm from the original slope surface. The reinforcement layer consists of a reinforcement net parallel to the slope surface and a vertical Anchor components on the slope. [0003] The horizontal projection area of ​​high and steep slopes is small, and the natural rainfall received and interc...

Problems solved by technology

There are two major disadvantages of automatic sprinkler irrigation on the ground: first, the accumulation of surface runoff on steep slopes is poor. Under the action of gravity, most of the water sprayed has no time to be absorbed by the slope soil, and it will flow directly along the slope surface to the slope foot, resulting in water resources Second, most of the slopes are uneven, and the automatic sprinkler irrigation system on the ground cannot fully cover the entire slope, leaving many dead spots. The plants located in these parts will be severely drought-stressed, resulting in local alopecia areata and slope ecological problems. Inconsistencies in the repair effect

Although manual watering can be used to replenish the slope soil with sufficient water at any time according to the needs, it is labor-intensive and has a low safety factor, and it is extremely inconvenient to operate under the site conditions of steep slope heights, and some dead spots will be left
