A rainwater recovery system for an overpass bridge and its installation method

Abstract

The invention mainly discloses a rainwater recovering system of an overpass bridge and an installation method thereof. According to the technical scheme, the rainwater recovering system comprises a bridge surface and bridge piers; a first flow guiding groove and a drainage ditch communicating with the first flow guiding groove are formed in the bridge surface, a first drainage pipe connected with a filter is installed in the drainage ditch, and the filter is connected with an underground water tank through a water purification pipe; and a first collecting hopper is installed at the top end of each bridge pier, a second collecting hopper communicating with the corresponding first collecting hopper is installed at the bottom end of each bridge pier, and each second collecting hopper is connected with the filter through a water falling pipe. According to the rainwater recovering system of the overpass bridge and the installation method thereof, the structure is simple, installation is convenient, the rainwater generated during rain falling or road purling can be quickly collected and stored, and drainage efficiency is improved; the rainwater is filtered and purified before storing, using efficiency of water resources is improved, and the water pollution problem is solved; and through the first collecting hoppers and the second collecting hoppers, the rainwater is prevented from entering the bridge piers, corroding the bridge piers or influencing appearance, and application and popularization are easy.

Description

technical field [0001] The invention relates to an overpass rainwater recovery system and an installation method thereof. Background technique [0002] With the acceleration of the urbanization process, the natural hydrological cycle processes such as evaporation and infiltration have been severely hindered, the increase in extreme weather, and the frequent occurrence of rainstorm and flood disasters have led to frequent urban waterlogging, water pollution, and a large loss of rainwater resources. There has been a trend of waterlogging every time it rains, but the groundwater level has been decreasing year after year, and the city's water shortage is extremely serious. Nowadays, people are paying more and more attention to the development and utilization of water resources. Rainwater is a precious water resource. If it is collected and used effectively, it will make a great contribution to energy conservation. [0003] While the urban overpass system brings convenient traff...
