Description

Revetment and water resource comprehensive utilization system based on honeycomb pipe-ecological blanket Technical Field The invention relates to the technical field of ecological restoration, in particular to a revetment and water resource comprehensive utilization system based on a honeycomb pipe-ecological blanket. Background Island and coastal-like areas often face special engineering and environmental challenges. The revetment soil body of the area is mostly composed of coral scraps, calcareous sand and other loose materials, and is low in structural strength, poor in cohesiveness and weak in self anti-scouring capability. Under the action of frequent typhoons, storm and waves, the slope is extremely easy to erode, develop in ravines and even collapse in shallow layers, and the slope feet are also frequently washed by water flow, so that the stability and safety of shoreside facilities are seriously threatened. At the same time, these areas often have extremely scarce fresh water resources. The area is limited, and an underground fresh water layer is lacked, so that fresh water supply is highly dependent on external transportation or high-energy consumption sea water desalination, and the cost is high and the sustainability is poor. Natural precipitation is a potential reliable fresh water source, but traditional shore protection engineering often hardens the earth surface, so that rainwater rapidly forms surface runoff to directly drain the sea, and the rainwater cannot be effectively collected and utilized, so that serious waste of water resources is caused. In prior art practice, revetment protection and rainwater collection are typically designed and constructed as two independent subsystems. On one hand, the conventional shore protection reinforcement scheme (such as deep anchoring by adopting a honeycomb anchor pipe or surface covering by laying an ecological blanket) mainly focuses on improving the mechanical stability, and the structure of the conventional shore protection reinforcement scheme is not designed with intercepting, guiding and utilizing functions on slope rainfall, so that precious fresh water resources are lost in the protection process. On the other hand, an independent rainwater collection system (such as a ground water collection pipe network, a water storage tank or sea water desalination equipment) often needs to occupy extra space, relies on complex pipeline layout and external energy supply, and is difficult to adapt to application scenes such as islands and reefs with limited space and weak infrastructure. Therefore, the prior art has the common problems of system fracture and single function. The shore protection engineering and the water resource management are mutually isolated in design and function, not only the repeated investment of materials, space and cost is caused, but also the function coordination among engineering measures and the maximization of the resource utilization efficiency cannot be realized. How to integrate the shore protection reinforcement with the rainwater collection, purification and utilization, thereby realizing the in-situ collection and utilization of fresh water resources while guaranteeing the stability of the bank slope becomes a technical problem to be solved urgently in the field. Disclosure of Invention The invention aims to provide a revetment and water resource comprehensive utilization system based on a honeycomb pipe-ecological blanket, which is used for solving the technical problems existing in the prior art. The shore protection and water resource comprehensive utilization system based on the honeycomb pipe-ecological blanket comprises a double-layer composite ecological blanket paved on a slope of the shore protection from top to bottom, multifunctional honeycomb anchor pipes implanted into the deep layer of the slope at certain intervals, a water collecting pipe network connected with a diversion structure of the double-layer composite ecological blanket, and a purifying and storing unit connected with the water collecting pipe network, wherein the double-layer composite ecological blanket is used for protecting the slope, penetrating and collecting rainwater, the multifunctional honeycomb anchor pipes pretreat partial split rainwater while providing deep anchoring force, and the water collecting pipe network conveys the collected rainwater to the purifying and storing unit which deeply processes the rainwater and stores produced fresh water. Optionally, the double-layer composite ecological blanket comprises a protective permeable layer, a transition layer and a water guide collecting layer from top to bottom. Optionally, the protective permeable layer is formed by weaving coral particles/scraps with the particle size of 0.5-1mm and salt-resistant polyester fibers, and the fiber gap is controlled between 1-2 mm. Optionally, the transition layer is a permeable geotextile. Optionally, the water guiding and collecting layer is
