The drainagecollecting mechanismis provided with a drainage channel, a cover, a supporting column, a drainage outlet, a water storage tank, a water inlet pipe, a water outlet pipe, a water outlet, a water outletpipe and a pressure valve, wherein the bridge body is provided with raining day detection mechanism; the raining day detection mechanism is provided with a fixing table, a water storage bottle, a mouth expanding collection pipe, a protective net, a water outlet, a water outlet guide pipe, a fixed plate, a fixed shaft, a movable floating ball and a small infrared distance meter, a drainage openingmechanism is arranged on the ladder-like drainage channel, the drainage opening mechanism is provided with a water permeable hole, an electric telescopic rod, a blocking plate, a blocking column and acircular opening, wherein a filtering mechanism is arranged in the water storage tank, and a rainwater secondary utilization mechanism is arranged in the water storage tank, and a controller is arranged on one side of the outer upper end of the water storage tank. The device has the advantages of simple structure and strong practicability.

Description

technical field [0001] The invention relates to the field of decoration and waterproofing, in particular to a drainage device for preventing water accumulation and seepage on bridges. Background technique [0002] At present, the common drainage devices on bridges generally have drainage outlets on the bridges, and then drain the water into the sewer through pipes. On the one hand, the rainwater is not collected for secondary use, and on the other hand, there are often plastic and wood on the drainage outlets. The entry of other impurities sometimes leads to blockage in the pipeline and affects the drainage efficiency, resulting in water accumulation on the bridge surface and affecting traffic. Contents of the invention [0003] The purpose of the present invention is in order to solve the above-mentioned problem, has designed a kind of drainage device that prevents accumulated water seepage on the bridge. [0004] To achieve the above object, the technical solution of th...
