Research On The Construction Of Ecological Slope Based On Sponge Technology And Its Preliminary Application

China is a country with a vast territory,complex terrain and a large amount of water resources.However,China’s per capita water resources are insufficient,and water resources are in short supply.Since 2014,“Sponge City” has been identified by China as a new model for urban construction.It plays a crucial role in the shortage of urban water resources and the protection of water systems.China is also a country with many mountains.The total area of mountainous regions,hills,and plateaus accounts for about two-thirds of the country’s total land area.Since the founding of New China,the construction of roads,railways,mines and other projects has caused the destruction of vegetation.A large number of exposed slopes have caused serious problems such as soil erosion and landslides.Many areas began to resume ecological restoration of slopes,but many of the ecological restorations of slopes ended due to the failure of water resources on the slopes.For this reason,based on the concept of sponge city and previous research,this paper puts forward the construction concept of "sponge slope" that conforms to nature,restores nature,and uses nature to build self-adjusting ability,environmental protection and conservation,and nature.Environmentally-coordinated ecological slopes give the green-slope nature of the slope.The fllowing are main research and conclusions of this paper:(1)Build a slope rainwater circulation system based on sponge technology.The slope rainwater cycle includes rainwater collection,rainwater treatment,storage and rainwater supply.When it rains,the slope collects rainwater while it is draining.After a simple treatment,it is brought into the reservoir for storage.When it is dry,it can directly use the water in the rainwater tank to irrigate the slope vegetation to achieve the recycling of rainwater.,to build an ecological slope that allows the recycling of rainwater.(2)Develop an automatic sprinkler system using fuzzy theory.Using the time control module,the daily watering time is controlled in a certain time period,so that the watering time is more reasonable.The soil and air temperature and humidity detection meter is used for information collection,and the collected information is subjected to fuzzy processing and the result is output to determine whether to spray.The time of showering and showering achieves no-manual automatic showering;the use of pressure sensors and fault location alarms enables the automatic alarm of system faults and the positioning of fault points.(3)Using FLAC3 D to study the stability of the slope after constructing the same-size reservoir with different sizes on the slope and building the same reservoir in different positions on the slope.The study found that the construction of reservoirs of the same size on different slopes has little effect on the stability of the slope;the stability of the slope and the maximum displacement of the slope when the same reservoir is built on different sides of the slope.With the increase of the construction site of the reservoir,it first increases and then decreases,and the position in the lower part of the slope reaches the maximum.(4)Initially construct a "sponge slope" in combination with actual projects.According to the rainfall situation in Fuling District of Chongqing City,the size of the reservoir was determined,and a certain slope of Shuangbao Road in Chongqing City was simulated using FLAC3 D.The stability of the slope was analyzed to determine the location of the reservoir and the construction of impoundment.The stability of the slope behind the pond was analyzed and compared with the results of the simulation of the ideal slope stability.The stability of the structure was obtained when the ideal slope was simulated.And from the rainwater collection,rainwater storage,automatic irrigation three aspects of the initial construction of the "sponge slope."The research results of this paper have important reference value for the use of rainwater resources and the construction of ecological slopes,as well as the design of automatic sprinkler systems.They can provide some references for the ecological restoration and construction of similar slopes and the design of automatic sprinkler systems.The basis.
