LID Multi-purposed open-channel type LID-hydraulic facility experiment

摘要

The present invention relates to a multipurpose number-of-road type LID experiment apparatus. The present invention relates to a method for constructing a target watershed model by applying the law of the superstructure to rivers in a watershed (river basin) unit and observing the phenomenon occurring when a low impact development (LID) technique is applied to the watershed And to analyze phenomena such as erosion, scouring, and sedimentation occurring in rivers according to the increase / decrease of runoff due to rainfall, and to analyze the total amount of suspended solids contained, In addition, it is possible to more precisely analyze the correlation between the erosion and scour phenomenon of the surface soil and the increase and decrease of the impregnation amount caused by the influent runoff in the case of the element technology composed only of the soil such as the infiltration ditch . The present invention relates to an LID test bed having an upper surface opened, a sample to be tested filled therein, a plurality of groundwater outflow holes formed on a bottom surface thereof, and a plurality of underground outflow holes formed on a side surface thereof by a stopper; A water collecting tank for supplying water to the LID test bed in a state of being installed outside the front end portion of the LID test bed; A rectifying tank formed integrally with a front end portion of the LID test bed in contact with the water collecting tank to rectify water flowing into the LID test bed from the water collecting tank; And a permeator for collecting the water flowing out through the groundwater outlet hole on the LID experiment bed through the outflow pipe.
