Road rainwater filtering device

Abstract

The invention provides a road rainwater filtering device. A filtering screen is arranged at the opening of the rainwater inlet end of a rainwater branch pipe, located on the same plane integrally and composed of ribs arranged in the transverse direction and in the longitudinal direction. The ribs comprise the main ribs and the auxiliary ribs, and the main ribs are thicker than the auxiliary ribs and form a filtering screen framework. The filtering screen completely covers the pipe opening or the middle and the lower part of the pipe opening. The invention further provides another road rainwater filtering device. The road rainwater filtering device can carry out secondary filtering to rainwater after a rainwater grate carries out primary filtering to the rainwater, sundries such as leaves, gravel and plastic bags are effectively prevented from entering the rainwater branch pipe, fewer sundries enter a rainwater pipeline or an inspection well, the cleaning frequency of drainage facilities such as the rainwater pipeline is lowered, abrasion of cleaning equipment is lowered, and the urban civilization level is improved to a certain degree.

Description

technical field [0001] The invention belongs to municipal road drainage engineering, in particular to a road rainwater filtering device. Background technique [0002] When it rains, urban road surface drainage mostly collects rainwater through the rainwater outlets set on both sides of the road and flows into underground drainage pipelines and other facilities, and then merges into rivers to achieve the purpose of urban drainage. The rainwater grate above the gully cannot filter out debris such as leaves, gravel, and plastic convenient bags, and gradually more debris will accumulate in the gully, especially when it rains, these debris directly enter the gully and pass through the rainwater The branch pipe directly flows into the inspection well pipeline, which may even cause blockage of the pipeline or the inspection well for a long time, affecting the drainage of the road surface. In order to prevent debris from entering the pipeline and increase the difficulty of inspec...
