In addition, it can help to prevent water pollution by purifying the discharged sewage, and when using rainwater, it is possible to install a sedimentation tank, so that manholes can be installed for rainwater and sewage.

Description

A manhole for combined use of gutter for the rainwater and and sewage}

The present invention relates to a manhole, in particular to show a manhole that can be performed as a function of rainwater and sewage.

In general, manholes are divided into storm water or sewage water. Rainwater dragons can be placed inside the sedimentation tank to filter out things such as foreign matter or sand, so that water can flow into the drainage well, but the sewage receiver is accompanied by a bad smell.

Therefore, the sewage receiver was installed when the hydraulic pressure acted to block the odor, and when the hydraulic pressure was removed, there was a damper of a structure that automatically shuts off the drain by self-weight or spring force.

However, until now, there have been no manholes that have functions of rainwater and sewage, and they have to be produced and installed separately for sewage and rainwater.

In particular, the odor counter flow prevention device of the sewage collecting device has a closed end that does not function properly when foreign matter is caught between the dampers or the spring is damaged.

The present invention was devised to solve the above-mentioned drawbacks, and it has a double structure to block the odor inside and installs a filtering net to filter out foreign substances or sand, if necessary. Its purpose is to provide a manhole that can serve as a base.

Another object of the present invention is to purify the sewage drained through the carbon basket to minimize water pollution.

The present invention for achieving the above object in the manhole consisting of a lid or grating is seated on the upper side and an outlet on the lower side of the inlet, the separator is installed in the center of the manhole hermetically separating the upper and lower airtight, the separation In the center of the plate, the lower end is located at the lower part of the outlet, and the lower pipe is immersed in the stored sewage and rainwater. The upper part of the lower pipe is detachably installed at the upper part of the upper part than the inlet. This is achieved by installing a tea basket and installing a second basket on the upper tube and a carbon basket on the lower tube as necessary.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view of the rainwater and sewage combined manhole according to the present invention, Figure 2 is a cross-sectional view of the rainwater and sewage combined manhole according to the present invention.

As shown, the main body 10 has a shape of normal light and bottom narrow, and an inlet 12 through which sewage is introduced is formed on one side, and an outlet 14 through which sewage and rainwater are discharged is provided on the lower side of the other side. The outlet 14 is installed at a position higher than the floor so that rainwater or sewage overflows into the outlet and is discharged. At this time, foreign matter mixed in the discharged rainwater or sewage is settled so as not to flow into the sewage, and the discharged sewage or rainwater is always maintained at the level of the discharge port (14).

In addition, the lid 16 is seated on the upper portion of the main body 10. The lid 16 has a grating 18 seated when the manhole is installed for rainwater, and a sewage lid 16 with a completely closed upper portion when used for sewage. In the case of rainwater and sewage combined, it is preferable that the rainwater lid 18 is seated.

The main body 10 may be configured in a rectangular cylinder, a circular shape, and various other shapes, and a separation plate 20 is disposed between the inlet 12 and the outlet 14 to partition the upper and lower chambers. It is. The separation plate 20 can be installed in an airtight manner without a separate structure by the shape of the body 10 is a normal light, and may be provided with a separation plate 20 by forming a step 24 in the body 10. have. In addition, a lower tube 22 is installed at the center lower portion of the separating plate 20, and a step 23 (see FIG. 1) is formed at an upper portion thereof so that the upper tube 25 is detachably installed. Of course, the upper tube 25 may be formed integrally with the lower tube (22).

The lower end of the lower tube 22 is located at a lower position than the height of the outlet 14 so as to be immersed in rainwater or sewage remaining at a certain level on the bottom, the upper tube 25 is higher than the inlet 12 In position, the water flowing from the inlet 12 overflows and is discharged.
