Rain sewage intercepting gate

Abstract

The invention discloses a rain sewage intercepting gate and relates to the technical field of rain sewage treatment. The rain sewage intercepting gate comprises an opening and closing machine, a steel structure gate body and an opening and closing machine beam, wherein the opening and closing machine beam is arranged on the top of the steel structure gate body; a draining opening is formed in the steel structure gate body; a cast iron gate which can vertically slide is arranged on the steel structure gate body and is used for sealing the draining opening; and the top part of the cast iron gate is connected with the opening and closing machine. As a steel structure form is adopted in the rain sewage intercepting gate provided by the invention, a plurality of steps in the existing rain sewage intercepting gate mounting process are eliminated, the mounting process is simplified, and a mounting period is greatly shortened; and furthermore, as the rain sewage intercepting gate is used by being matched with a rain sewage pipeline, the probability of seepage is reduced, and air-tightness is good.

Description

technical field [0001] The invention relates to the technical field of rain and sewage treatment, in particular to a rain and sewage interception gate. Background technique [0002] The interception of rainwater and sewage is mainly to prevent the sewage discharged by humans from directly flowing into the natural water body to pollute and protect the water quality environment, and to collect the sewage discharged from production and life through pipelines in an organized way (note: 100% collection may not be achieved, and generally can It is good enough to achieve more than 85%, and those that cannot be intercepted can only run away through infiltration, evaporation, and flow into rivers, etc.), and then collected through pipelines, flow into intercepted main pipes, and then transported to municipal sewage treatment plants for centralized treatment , The practice of discharging into natural water bodies after treatment reaches the standard is called sewage interception. The...

AI Technical Summary

Problems solved by technology

This kind of intercepting main pipe generally has a large diameter, and the construction is more difficult and the cost is higher.

Generally, the interception main pipe is equipped with an interception gate, but the installation of the existing rain and sewage interception gate is time-consuming and consumes a lot of manpower. After the drainage gate is installed, secondary grouting is required, and deformation is easy to occur during the secondary grouting. There may even be rework, which is very inconvenient to use, and the deformed drainage gate is prone to water seepage
