Highway slope drainage structure

Abstract

The invention discloses a highway side slope drainage structure, relating to the field of highway drainage, The structure comprises a water storage tank and a lower water tank, wherein a floating plate is vertically slid and connected in the water storage tank, one side of the floating plate is fixedly connected with a water blocking plate inserted in the lower water tank, one side of the water blocking plate is abutted on the side of the lower water tank close to the slope, a drainage pipe is arranged in the slope, and the lower end of the drainage pipe extends to the lower end of the slope;The water blocking plate is provided with a flow restriction hole communicated with the lower water tank; Normally, the upper edge of the restriction orifice is lower than the upper edge of the upperorifice of the drain pipe, and the lower edge of the restriction orifice is lower than the lower edge of the lower orifice of the drain pipe. The drain pipe is also evenly provided with a water permeable hole. As that rainfall amount is small, the rainwater enter the drainage pipe and is quickly drained away by the drainage pipe, so that the water does not permeate into the interior of the slopeand is drained away, and the rainwater has the advantage that the flow rate in the water pipe can be automatically regulated, the flow time of the rainwater in the drainage pipe can be prolonged, andthe rainwater can penetrate into the interior of the slope for a long time.

Description

Technical field [0001] The invention relates to the field of highway drainage, in particular to a highway side slope drainage structure. Background technique [0002] With the rapid development of my country's economy, the mileage of expressways has been increasing. More and more attention is paid to the maintenance of expressways. The early damage to the expressway is the first “culprit”. The drainage design is related to the life and use cost of the expressway. In order to prevent the accumulation of water in the center of the road when it rains, the general setting of the expressway is The high and low sides in the middle of the structure allow the water in the center of the expressway to flow to both sides of the expressway, and finally drain the accumulated water on the road surface of the expressway through the drainage structure on both sides of the expressway. [0003] At present, there are two types of drainage methods for side slopes on both sides of the expressway: cent...

Problems solved by technology

However, when the rainfall is low, when a small amount of rainwater enters the drain pipe, it will be quickly drained away by the drain pipe, causing the water in the drain pipe to flow to the drain before it penetrates into the slope. In addition, the above-mentioned Valves are installed at the lower end of the drainpipe in the multi-functional dense-porous highway slope drainage structure, but the flow rate of rainwater cannot be changed. It can only accumulate rainwater in the lower part of the downpipe, thereby penetrating to the bottom of the slope, and the upper part of the slope remains the same. Water seepage cannot be achieved
