Abstract

The embodiment of the invention provides an environment-friendly drainage system for municipal engineering. According to the environment-friendly drainage system for the municipal engineering, a pipeline with a U-shaped cross section is arranged beside a municipal drainage opening, after the municipal drainage opening is blocked, the water level at the municipal drainage opening rises, and when the water level rises to the height of a water inlet of the pipeline, rainwater flows in from the water inlet of the pipeline and flows to the bottom of the pipeline with the U-shaped cross section. Due to the fact that a communicating vessel principle is adopted, along with inflow of rainwater, a floating block located in the other side wall of the pipeline rises along with rising of the water level in the pipeline, and in the rising process of the floating block, a baffle arranged on the floating block is driven to move upwards till the floating block makes contact with a limiting plate; and at the moment, the baffle can block rainwater higher than the municipal drainage opening so as to prevent a sidewalk beside the municipal drainage opening from being submerged.

Description

technical field [0001] The invention relates to the technical field of municipal drainage engineering, in particular to an environmental protection drainage system for municipal engineering. Background technique [0002] Municipal drainage refers to the rainwater and sewage pipes under the municipal roads, commonly known as "sewage pipes", which are usually called municipal drainage pipes in engineering. According to the current situation of facilities under municipal roads in China, different pipelines are generally set up, such as electricity, communication, gas, water supply, drainage pipelines, etc. As for the drainage pipeline, due to the consideration of rain and sewage diversion measures, that is, rainwater is generally discharged into the river nearby, and sewage is discharged into the sewage treatment plant, so the municipal drainage pipe includes two kinds of pipes, rainwater and sewage. [0003] Corresponding to the existing rainwater drainage pipes, in order to ...
