Description

Intelligent protection structure and method for slope rainwater storage, drainage and maintenance integration Technical Field The invention relates to the technical field of ecological slope protection, in particular to an intelligent slope protection structure and method integrating rainwater storage, drainage and maintenance. Background The side slope is used as a common geological structure in engineering construction of roads, water conservancy, mines and the like, and the stability of the side slope is directly related to engineering safety and ecological environment. In natural environment, the side slope is easily affected by rainfall, weathering and other factors, when geological disasters such as landslide, soil erosion, water and soil loss and the like are caused, a large amount of rainwater permeates into the slope body to increase the weight of the slope body, meanwhile, the water content of the soil rises to reduce the internal cohesive force and further aggravate disaster risks, and in drought period, vegetation on the side slope surface is difficult to survive due to water shortage, the side slope stability cannot be enhanced through the root system soil fixing effect, and the ecological protection effect is poor. In order to solve the problems, various side slope protection and maintenance schemes are proposed in the prior art. For example, some technologies realize rainwater drainage and storage through structures such as a drainage ditch and a water storage pool, and repair slope environments by combining ecological greening means, but the scheme has multiple emphasis on single drainage or ecological restoration functions, lacks self-adaptive protection capability for different rainfall capacities, is still easy to cause structural instability due to slope soil scouring in heavy rainfall, and other technologies design a slope drainage and storage and automatic irrigation device, so that the stored rainwater is used for vegetation irrigation, but the irrigation start of the device depends on manual control or fixed electric drive, the slope protection state cannot be automatically adjusted according to rainfall intensity, and the retraction of a protection film requires additional power sources, so that the operation is complex and the energy consumption is higher. The existing slope protection technology has the following defects that firstly, drainage and protection cooperativity are poor, most drainage devices can only realize rainwater drainage, slope protection cannot be automatically started during heavy rainfall, soil bodies in a funnel-shaped water collecting area are easy to wash and destroy, secondly, the utilization rate of rainwater resources is low, stored rainwater is mainly used for simple irrigation, a closed loop system of saving, drainage, protection and irrigation is not formed, thirdly, the retraction and release of a protection film lacks a stable tension adjustment mechanism, the problems of film loosening, breaking or untimely recovery easily occur, fourthly, soil matrixes are difficult to meet the requirements of washing resistance and plant growth, or the soil matrixes are insufficient in bonding strength and easy to run off, or excessive solidification leads to low seed germination rate, and fifthly, the irrigation system is high in energy consumption and difficult to use under a non-power supply scene. In addition, each functional unit (drainage, protection, irrigation) of traditional side slope protector is independent relatively, lacks integrated design, leads to the structure complicacy, the construction degree of difficulty is big, and self-adaptation ability is not enough, can't be according to real-time working condition dynamic adjustment operating condition such as rainfall intensity, environmental humidity. Therefore, there is a need for a slope protection system that can achieve adaptive protection of rainfall, recycling of rainwater, low energy consumption irrigation maintenance, and structural integration, so as to solve the above-mentioned drawbacks in the prior art. Disclosure of Invention The invention aims to overcome the defects and provide an intelligent integrated slope rainwater storage, drainage and maintenance protection structure and method, so as to solve the problems in the background technology. The technical scheme includes that the intelligent slope rainwater storage, drainage and maintenance integrated protection structure comprises a rainfall storage unit, a slope body protection unit, a drip irrigation unit and a soil matrix layer, wherein the rainfall storage unit comprises a water storage well, a drainage groove and a lattice type anchor rod support structure, the water storage well and the drainage groove are formed in a slope, an overflow port of the water storage well is connected with a water inlet of the drainage groove, a water outlet of the drainage groove is communicated with drainage channels at two sides of a road, the la
