Manhole device with drainage structure {Manhole with drainage system}

The present invention relates to a manhole device embedded in the basement, and more particularly, to install a water collecting well downwardly projected on the bottom surface of the manhole body, and to install a drain pipe having a non-return valve in one direction to open the water collecting well, By forming a gravel layer at the outlet of the drain pipe, the water flowing into the manhole body to be discharged to the outside naturally, to prevent the automatic discharge of water flowing into the manhole device and the damage of various internal devices installed in the manhole device in advance. Manhole device with drainage structure.

In general, the manhole is used to easily maintain or control various underground buried wire wiring devices such as the valve device of the water and sewage pipes buried underground or the communication cable or the power cable. Most of these manholes are made of reinforced concrete. It is composed of the body.

However, these concrete manholes take a long time to cure, resulting in a decrease in productivity. When installing them, tools such as hammers and chisels are used on both sides of the floor to suit the diameter size of the water pipe, sewer pipe or underground cable for power / communication. It should be dug into "U" type so that water, sewage pipes, underground cables, etc. can pass through. In this case, the gripping shape is changed according to the skill of the worker. As a result, the lifespan of the manhole is reduced, as well as when the construction of the manhorn on site has a variety of problems such as covering the upper part of the manhole can not be covered with soil until the cover is cured by the concrete.

Therefore, in consideration of the above problems, I have been registered as a registered utility model No. 20-0291458, which was previously filed, which forms a manhole body made of a metal tube and a manhole entrance formed on the upper side thereof. It is formed integrally, but by forming the cover body in a curved dome shape upward, the manhole body is made of a metal body to produce a manhole quickly, so as not to be easily broken like a conventional concrete manhole,

It is basic to allow the manhole to be covered immediately after construction in the field without the inconvenience of waiting for the concrete to cure as in the prior art, and the curved dome-shaped cover body strengthens the force to withstand external stress, The manhole cover is formed on the bottom of the manhole cover that blocks the manhole entrance, and when the manhole cover is combined, the manhole entrance is completely sealed by the seal ring so that water never penetrates into the manhole through the manhole cover. And the construction is convenient, and to strengthen the strength of the manhole to make a long life, to suppress the penetration of water to make the maintenance and control of various devices in the manhole convenient.

However, in spite of the above-mentioned advantages, the present invention of the present invention is that its disadvantages are exposed, which is because the lower part of the manhole body has an open structure, and the passage through which the upper and the sewer pipes are formed by a cutting method. After embedding the manhole device in the basement, rainwater or submerged water flows into the manhole device, causing problems such as corrosion of various devices inside the manhole device.

Accordingly, in view of the above problems, the present applicant has been registered with the Utility Model Registration No. 20-0436633, which is formed on the upper surface of the manhole body made of a metal square tube body, the structure of the guide portion is coupled to the manhole cover special Formed to make it easy to insert even the relatively large devices that could not be inserted into the existing manhole device,

Separating the manhole body horizontally and assembling and disassembling makes it easy to manufacture and transport, as well as perfectly inserts even internal devices that are so large that they cannot be inserted or extracted through the specially configured guide. Or withdrawals to make repairing and replacing internal devices even easier.

In particular, it is installed in the manhole body by integrally forming the drain pump installation part projecting downward on the bottom surface of the manhole body and installing a drain pump operated by the water level sensor to automatically discharge the water flowing into the manhole body to the outside. It is to prevent the damage of various internal devices.

However, in spite of the advantages described above, the design of the original application of the present inventors has exposed its disadvantages, which is composed of a drain pump which detects water by a sensor and is electrically operated, and a drain pipe drawn out through the manhole device. Invar, the drain pump and the drain pipe is installed inside the manhole body there was a problem receiving a proposal for the utilization of the manhole body space.

In addition, there is a problem that causes the operation of various devices such as a valve device, a communication cable, a power cable, etc. installed in the manhole body by a drain pump that is electrically operated to generate noise and vibration.
