Rain water seepage well lid for urban green land

Abstract

The invention relates to a rain water seepage well lid for an urban green land, which comprises a well frame and a well lid. The rail water seepage well lid is characterized in that the well lid adopts a cone frustum type recess; a perforation plate card is arranged in the cone frustum type recess; a perforation plate is lapped on the perforation plate card to divide the well lid into an upper layer and a lower layer; the upper layer adopts a vegetation planting layer; and the lower layer adopts a water storage layer; the outer edge of the well lid is lapped on circular grids of the well frame; the well frame consists of a circular ring, a soil retaining ring and the circular grids; the soil retaining ring is arranged above the well frame; the diameter of the soil retaining ring is equal to the outer diameter of the circular ring; and the circular grids are vertically mounted on the edge of the inner diameter of the circular ring. The upper layer of the well lid adopts the vegetation planting layer; redundant rain water collected by the well lid when rain falls can be stored in the water storage layer, and is used for the growth of vegetation in a lid plate in the non-rain falling period. And the well lid can improve the overall aesthetics of the green land under the condition of not influencing water entrance.

Description

technical field [0001] The invention relates to a manhole cover for rainwater seepage in urban green areas, which belongs to the field of urban rainwater control and utilization. Background technique [0002] With the acceleration of urbanization, the urban impermeable ground has increased significantly, resulting in an increase in the urban surface runoff coefficient, which has caused major cities to suffer from floods and floods caused by sudden heavy rains and stagnant water. In order to solve such problems, in recent years, the use of concave green spaces in cities has become more and more popular. The application of concave green spaces in cities has the functions of supplementing groundwater, regulating runoff, flood detention, and reducing runoff pollutants, providing rainwater infiltration Generally, seepage wells are scattered in the green land, and the seepage wells act as underground water collection devices. After the rainwater is accumulated, it spreads to the s...
