Description

Highway roadbed slope drainage structures Technical Field The utility model relates to the technical field of highway drainage, in particular to a highway subgrade slope drainage structure. Background The water on the side slope of the highway subgrade is drained, namely, the water is used for intercepting and guiding the surface water on the side slope or on the side slope to flow to a designated drainage path, so that the water is prevented from directly flushing the highway subgrade, the subgrade is prevented from being damaged by the water, and the strength and the stability of the subgrade are ensured; However, the highway subgrade slope drainage structures of the prior art still have some drawbacks: In the highway construction process, the relevant structure of roadbed side slope drainage is most pre-buried between highway and side slope, and during raining, the rainwater of leaving on the side slope is led, and highway roadbed side slope drainage structure adopts drainage channel, drainage channel and drain pipe isotructure generally, and wherein, the apron of drainage channel top is used for the interception of stone, leaf and other debris, avoids debris to get into, owing to has only set up one deck interception structure to make the interception effect of debris relatively poor, lead to structure such as drain pipe jam easily, increased the maintenance frequency of drain pipe. Disclosure of utility model In order to solve the problems, the utility model aims to provide a highway subgrade slope drainage structure. In order to solve the technical problems, the utility model adopts the following technical scheme that the highway subgrade slope drainage structure comprises a drainage channel, a drain pipe and a maintenance well, wherein one end of the drainage channel is communicated with the inner cavity of the drainage channel, the other end of the drainage channel is communicated with the inner cavity of the drain pipe, the drain pipe penetrates through the maintenance well, a cover plate is movably arranged at the opening end of the drainage channel, a confluence groove is arranged on the upper surface of the cover plate, the confluence groove is of a trapezoid structure with an upper end opening larger than a bottom end opening, and a plurality of evenly distributed anti-fouling grooves are arranged on the bottom wall of the confluence groove; the inside of the drainage channel is provided with a filtering component, the filtering component comprises a U-shaped frame, the length and width dimensions of the U-shaped frame are smaller than the length and width dimensions of the inner cavity of the drainage channel, the opening dimensions of the U-shaped frame are larger than the bottom opening dimensions of the converging grooves, and the U-shaped frame is detachably arranged in the inner cavity of the drainage channel; A plurality of evenly distributed filter tanks are arranged on the bottom wall and the peripheral wall of the U-shaped frame, and the opening size of the filter tanks is smaller than that of the anti-fouling tank.
