Description

Simple manhole of rain gutter drainage {A portable manhole for gully hole of Rainwater case}

The present invention relates to a simple manhole of rain gutter sewers, and more specifically, to prevent the reverse flow of sewage and odors, and to collect and separate soil sand, cigarette butts and garbage mixed with rain or sewage. It is about the simple manhole of the sink drain.

In general, manholes are installed on the roadside to discharge rainwater or sewage. Manholes are connected to sewer pipes buried underground. Therefore, the collected rainwater or sewage is discharged to a sewage treatment plant or a river.

On the other hand, on the open top of the manhole, a grid-shaped manhole cover, also called "steel grating," is installed to filter out large, coarse foreign matter.

However, these manholes and sewage pipes have a problem of allowing backflow of sewage when heavy rain or rainy season prevents the discharge of sewage smoothly. In particular, there is a problem of polluting the road by discharging the reversed sewage as it is on the road.

In addition, the conventional manholes and sewage pipes have a problem in that the odor of the sewage flowing along the inside is directly flowed back. In particular, there is a problem of polluting surrounding air by releasing backflow odor into the atmosphere.

In view of this, a "sewage and odor backflow prevention device" for preventing backflow of sewage and odors has been developed.

This technique, as shown in Figure 1, by installing a pair of doors (3) facing on the sewer passage (1), when the sewage flows open the sewer passage (1), When the inflow is stopped or the sewage backflow is configured to block the sewer passage (1).

Such a prior art prevents the backflow of sewage at the source even if the sewage flow is closed when the sewage flows back, even when heavy rain or rainy season makes it difficult to discharge the sewage.

In addition, when there is no discharge of sewage, the sewage passage 1 is closed, thereby preventing backflow of the odor of sewage flowing along the sewage pipe. This prevents backflow odors from being released into the atmosphere.

By the way, this conventional technique has the advantage of preventing the backflow of rainwater, sewage and odor, but when the rainwater or sewage flows in, it is impossible to filter and collect soil sand, cigarette butts or garbage mixed with rainwater or sewage. There was a problem to pass.

And because of these shortcomings, it was pointed out that soil sand, cigarette butts and garbage were mixed with rainwater or sewage and flowed into the sewer pipes underground. In particular, the problem is that the sand is accumulated on the bottom of the manhole or flows into the sewage pipe to block the underground sewer pipe or to reduce the sewage flow to cause bad smell.

The present invention has been proposed to solve the above problems in consideration of the above problems, an object of the present invention is a rain gutter to prevent the backflow of sewage and backflow of odor by a catchment drainage acts as a drainage trap (drainage trap) It is to provide a simple manhole of the sewer.
