A rainwater well with filtering function and convenient for flood discharge for municipal drainage

Abstract

The invention discloses a catch basin with a filtering function and flood discharging convenience for municipal drainage. The catch basin main body comprises an outer ring, a transverse well body, a longitudinal well body and an upper ring, the transverse well body and the longitudinal well body are both tubular, and the transverse well body is horizontally placed at the bottom of the catch basin;the longitudinal well body is perpendicularly placed in the middle on the transverse well body, the transverse well body is internally communicated with the longitudinal well body, and the upper ringis arranged on the top of the longitudinal well body; clamping grooves are formed in the front and back protruding portions of the upper ring, the bottom of the upper ring on the longitudinal well body is a two-stage step, and one-stage step is arranged under the second-stage step; an oblique surface is arranged under the one-stage step, several perpendicular locating columns are arranged on theoblique surface, a filtering screen is placed on the longitudinal well body, and the bottom of an upper circle on the upper side of the filtering screen is placed above the portion, of the one-stage step, on the upper side inside the longitudinal well body. When the catch basin with the filtering function and the flood discharging convenience for municipal drainage is in conventional use, a flooddischarging groove can be closed to reduce the flow and strengthen the effect of filtering impurities, when water is accumulated, the filtering screen can be pulled through a hand wheel to open the flood discharging groove, and the catch basin can be widely used and popularized.

Description

Technical field [0001] The invention belongs to the technical field of construction engineering, and specifically relates to a rainwater well with filtering function and convenient for flood discharge for municipal drainage. Background technique [0002] When there is heavy rainfall, there is water in some sections of urban roads, which seriously affects the safe passage of vehicles and pedestrians. Rainwater wells are used for ground roads or gas pipelines to dredge rainwater, and the design of rainwater well covers is related to the difficulty of the drainage system. Nowadays, the common rainwater well covers on the market are steel grating rainwater well covers, such as steam manhole covers on roads. The drainage effect of the rainwater manhole cover is not very good, and it is easy to be blocked. In case of heavy rain or flood, the rainwater cannot be discharged to the sewer in time, resulting in road traffic inconvenience and prone to safety accidents. Therefore, the manhole...

Problems solved by technology

[0002] When there is a large amount of rainfall, some sections of urban roads sometimes have waterlogging, which seriously affects the safe passage of vehicles and pedestrians

Rainwater wells are used for ground roads or gas pipelines to dredge rainwater, etc., and the design of rainwater well covers is related to the difficulty of the drainage system. Now the common rainwater well covers on the market are steel grating rainwater well covers, such as steam well covers on the road. The drainage effect of the rainwater manhole cover is not very good, and it is easy to block. In case of heavy rain or flood, the rainwater cannot be discharged to the sewer in time, resulting in inconvenient road traffic and prone to safety accidents. Therefore, the manhole cover device with simple design and easy access to rainwater in emergency situations is very important
