FLOW GATE OF MANHOLE

The present invention relates to a floor gate for a sewer, comprising a first pipe having an inlet on the upper side of the sewer, and a second pipe communicating with the first pipe and connected to the sewer, Even when drainage is not performed due to this accumulation, the fluid flows into the inlet of the first pipe formed on the upper side of the sewer so that it can be smoothly drained. It relates to a floor gate for a sewer that can create a clean and sanitary environment as it flows into a pipe and drains.

In general, a drainage structure for discharging rainwater or sewage is installed on a road or road. The drainage structure is connected to a sewage pipe buried underground to transport collected rainwater or sewage to a sewage treatment plant or river. Here, a lattice structure (sewage manhole), also called "steel grating", is installed on the open upper part of the drainage structure to filter out large and rough foreign substances.

However, when fallen leaves or foreign substances are accumulated on the upper part of the sewage manhole, it is difficult to perform the function of drainage, causing problems such as backflow of water and overflow of water on the road.

Therefore, various technologies for preventing garbage from accumulating in the sewage manhole or cover are being proposed in various ways.

As related prior art, Registered Patent No. 10-1335863 "Odor blocking device having a function to prevent waste entry for sewer manholes" (hereinafter referred to as 'Prior Art 1'), Registered Utility Model No. 20-0268563 "Sewer foreign substances inflow prevention device" (hereinafter referred to as 'prior art 2').
