Novel rainwater perforated strainer suitable for being used in sponge city

Abstract

The novel rainwater grate of the present invention is suitable for collecting rainwater from roads and squares in sponge cities, and includes a grate body and a grate cover. Holes of a certain diameter are evenly arranged in the upper part. The grate cover plate is a square panel. There are water seepage holes of a certain diameter and a certain width range evenly arranged around the cover plate. There is a certain height of isolation under the cover plate. There are holes of a certain aperture uniformly arranged on the upper and lower parts of the isolation plate, and the diversion reinforcement plate connects the panel and the isolation plate. The new rainwater grate can be made of different materials according to the installation position to meet the load requirements. The invention solves the problem of sand and other heavy particles flowing into the rainwater well, solves the problem of larger floating objects entering the rainwater well, solves the problem of peculiar smell in the rainwater well, and solves the problem of road garbage falling into the rainwater well in dry season.

Description

Technical field [0001] The invention relates to a rainwater grate, in particular to a new type of rainwater grate suitable for use in the construction of sponge city roads and squares. Background technique [0002] The construction of sponge cities is the direction of the country's urban development for some time to come. In places where rainwater is concentrated, such as urban roads and squares, many pilot areas still use old-fashioned rainwater grate. This old-fashioned rainwater grate has several disadvantages that cannot be overcome: the sediment and larger-shaped floating objects carried in the rainwater flow into the rainwater pipe due to the large space of the grate; the rainwater well cannot be discharged in time for a long time. The water quality deteriorates and emits peculiar smell; in the rainless season, rubbish in the road square is easy to fall into the rain well, and over time, garbage pits are formed. Summary of the invention [0003] The technical solution of t...

Problems solved by technology

This kind of old-fashioned rainwater grate has several defects that cannot be overcome: the sediment and larger floating objects in the rainwater flow into the rainwater pipe because the grate has a large space and cannot be intercepted; the rainwater well collects water for a long time and cannot be discharged in time. The water quality deteriorates and emits peculiar smell; in the rainless season, the garbage in the road square is easy to fall into the rainwater well, and after a long time, a garbage pit will be formed
