Abstract

A drainage manhole of the present invention comprises: a house inlet laid under the underground; a riser pipe installed at the top of the house inlet; and a cover installed at the top of the riser pipe. A riser pipe connection hole is formed at the top of the riser pipe and inlet holes and a discharge hole are formed on the outer circumference. The three inlet holes are formed in the front of the house inlet. One inlet hole is each formed at both sides. The discharge hole is formed at the rear surface. A reverse U-shaped trap partition is formed at the inner front lower end of the house inlet. A trap water storage space is formed inside of the trap partition. A trap elbow is installed at the front central inlet to discharge sewage into the trap water storage space. The house inlet is easily manufactured by a simple structure of a deodorization trap. A pleasant surrounding environment can be maintained by preventing inner noise of the house inlet from being delivered to the outside. The sewage in the trap water storage space is prevented from being frozen or flowing backwards to the indoor.

Description

Drainage manhole {a manhole}

The present invention relates to a drainage manhole that collects and discharges various wastewater discharged from homes, and more particularly, to easily prepare a deodorization trap in the wastewater collecting tray, and to freeze the sewage filled in the trap reservoir in winter. It is about making it possible to prevent it.

In general, a drainage manhole for collecting and discharging various wastewater discharged from a home, etc., has a prized pipe installed at an upper portion of a sewage receiver buried underground, and a lid installed at an upper portion of the prized pipe.

And the drainage in the drainage manhole is provided with a granular pipe connection at the upper portion, and a plurality of inlets for allowing the waste water from the bathroom, kitchen, laundry room, etc. of the home to enter the inner periphery, and the sewage into the It is usually configured in the form of one outlet for discharging the collected waste water to the sewage treatment plant.

Meanwhile, in the drainage manhole, there are many examples in which a deodorization trap is provided to prevent the odor generated from the sewage inside the sewage trap back to the room. However, in the related art, the deodorization trap is complicated, which makes it difficult to manufacture the sewage catcher. There was.

In addition, the deodorization trap of the sewage receiver has a trap reservoir space which always maintains a state in which the sewage is filled. In the related art, the sewage filled in the trap reservoir space is frozen in winter so that the sewage inlet connected to the trap reservoir space is closed. Therefore, there was a problem that the waste water back to the room.

The present invention has been made in view of the above-mentioned conventional problems, and the object thereof is to provide a deodorization trap to prevent the introduction of odor into the sewage receiver, so that the cost can be reduced and the productivity and functionality can be improved. It is to provide a drainage manhole.

In addition, another object of the present invention is to provide a drainage manhole that prevents the sewage filled in the trap reservoir space of the deodorization trap of the winter to freeze the sewage backflow into the room.

The drainage manhole of the present invention for achieving the above object is a sewage receiver buried underground; A standing tube installed at an upper portion of the sewage receiving unit; And a lid installed on an upper portion of the granular tube. The sewage receiver is provided in the upper part of the drainage pipe is provided with a connecting pipe connection, a plurality of inlets and one outlet in the outer circumference, three inlets are provided on the front of the sewage receiver, one each on each side Provide an inlet port, and provide an outlet port at the rear, provide an inverted U-shaped trap partition wall at the inner front bottom of the sewage receiver, provide a trap reservoir space inside the trap partition wall, and sewage into the trap reservoir space at the front central inlet port. A trap elbow is installed to discharge the gas.

In the drainage manhole of the present invention, both front inlets of the sewage receiver are provided to the outside of the trap partition wall, and both side inlets of the sewage receiver are provided with a bent portion bent toward the outlet at the rear end thereof.

On the other hand, in the drainage manhole of the present invention, the inner top of the granular pipe is installed with an inner lid filled with a heat insulating material, and the granular pipe is formed in a form in which soft plastic is integrally formed on the outer side of the hard plastic.

The drainage manhole of the present invention is capable of introducing sewage in various paths through a plurality of inlets provided in the sewage receiving device, and the deodorization trap structure is simple, so that the sewage collecting device can be easily manufactured.

The drainage manhole of the present invention prevents internal noise from being transmitted to the outside through an inner lid filled with a heat insulating material, and a granular pipe composed of a double pipe of hard plastic and soft plastic, thereby keeping the surrounding environment pleasant as well as cold outside. The air can be prevented from entering the sewage collector, thereby preventing the sewage in the trap reservoir space from freezing or returning to the room.
