The present invention relates to a prefabricated manhole device, and more specifically, the structure of the guide part to which the manhole body and the manhole cover made of a metal rectangular tube are combined to be specially formed to be assembled at a construction site to facilitate manufacturing and transportation. In addition to zooming, it is possible to easily insert or withdraw even large-sized devices that could not be inserted into the existing manhole entrances in the manhole device, making installation, repair and replacement of the internal devices easier.

Variously installed in the manhole body by integrally forming the drain pump installation part projected 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 prevents damage of internal devices beforehand,

The present invention relates to a prefabricated manhole device that can be replaced with a new manhole device without dismantling various internal devices such as a flow meter, a pressure reducing valve, and a distillation valve when the old manhole device is selectively replaced.

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 low productivity,

When constructing this, dug both sides of the bottom surface into “U” type with tools such as hammer and chisel to fit the diameter size of water, sewage pipe or underground cable for power / communication. In such a case, the gripping form is changed according to the skill of the operator. In addition, the impact is incorrectly transmitted, so that a crack occurs in a part of the body, which shortens the lifespan of the manhole and also installs the manhorn in the field. When the cover to cover the upper portion of the when formed by the concrete had a number of problems, such as not covering the manhole with soil until the cover is cured.

In consideration of the above-mentioned problems, there is a Utility Model Registration Application No. 2002-19701.

It forms a manhole body made of a metal square tube and integrally forms a cover body formed with a manhole inlet on the upper side thereof, and the manhole body is made of metal by forming the cover body in a curved upward shape. To produce,

It is not easy to break 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 before.

In addition, 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, despite the above-mentioned advantages, my elected draft is not only easy to carry and store because of its relatively large weight and large size.

Since the diameter of the manhole inlet provided at the upper end of the guide part integrally formed on the upper cover body of the manhole body is small, the size of various internal devices installed therein is not possible at all even if the size is slightly larger than the manhole inlet. According to the size of the internal equipment to be introduced, the economic inconvenience of having to produce a manhole body of various items having different sizes of the manhole entrance was followed.

In addition, if the size of various internal devices such as a flow meter, pressure reducing valve, or distillation valve is very large, the existing manhole device should be replaced without disassembling the existing internal devices or cutting the metal manhole body with an oxygen welder. There was no more.

Therefore, with other manhole devices that have been made in the past, it is necessary to install, repair or replace various devices in the manhole device, as well as to replace the old manhole device as much time, labor and cost as necessary. Not only this, but also such long-term maintenance work could not fundamentally solve all problems such as civil complaints caused by grievances related to water, sewage, power and communication.

The present invention was devised in view of the above problems,

It is formed on the upper surface of the manhole body made of metal square tube, and specially forms the structure of the guide part to which the manhole cover is coupled, so that even a relatively large device that cannot be inserted into the existing manhole device can be easily inserted. ,

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.

Variously installed in the manhole body by integrally forming the drain pump installation part projected downward on the bottom 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. Prevents damage to internal devices

In addition, the lower body is also cut into a longitudinal section based on the conduit connector to separate the left lower body and the right lower body, but the welded part of them or to form a flange on each of the cut parts and obsolete manhole device It is possible to exert various functions such as re-cutting the lower body or releasing the fastened bolt to separate the left lower body and the lower right body without disassembling the existing various internal devices. The purpose is to provide a multi-functional high-quality manhole device to solve many inconveniences caused by the installation and replacement of the manhole at one time so that workers and citizens can be satisfied at the same time.

Hereinafter, the present invention for achieving the above object will be described in detail based on the accompanying drawings.

The present invention is as shown in the accompanying drawings, Figures 1a to 1d

A manhole body 100 formed of a metal or circular or square shape is formed, and the manhole inlet 311 to which the manhole cover 200 is coupled is formed on the upper surface of the manhole body 100.

As the manhole device formed on both sides of the manhole body 100, at least one or more pipe connectors 120a are coupled to the upper and lower sewer pipes or underground cables for power / communication.

The middle portion of the manhole body 100 is laterally cut to separate the upper body 110 and the lower body 120 and

These cut portions are formed with flanges 111 and 121 to which the packing 140 is coupled to the inner surface, respectively.

On the other hand, the side stopper 121a is formed upwardly protruding on the outer surface of the flange 121 formed at the horizontal cut portion of the lower body 120 so that the lower end of the upper body 110 is guided to the inside of the side stopper 121a. It is configured to be.

And, the guide portion 300 is formed on the upper body 110, the upper surface so that the manhole cover 200 is coupled,

Overall, the body formed to be shorter than the diameter of the upper manhole opening 311 to which the manhole cover 200 is coupled is larger than the upper guide portion 310 and the lower guide portion 320,

It is configured to couple the upper guide portion 310 formed with a manhole inlet 311 to the upper side of the lower guide portion 320 integrally formed on the upper surface of the upper body 110.

Here, the present invention is formed integrally with the drain pump installation portion 150 protruded downward on the bottom surface (120b) of the lower body 120 constituting the manhole body 100 by the water level sensor 151 By installing the operating drainage pump 152 into the manhole body 100 to automatically discharge water accumulated in the drainage pump installation unit 150 protruding downward from the bottom surface 120b to the outside of the manhole body 100 automatically. It may be configured to prevent the damage of various internal devices installed in the manhole body 100 in advance.

In addition, the present invention, as shown in Figure 2 of the accompanying drawings, the lower body 120 is cut into longitudinal on the basis of the pipe connector (120a) to the lower left body 120 'and the right lower body 120 " Separately configured, but can also be welded to these cuts, or to form a flange 160 and bolted to each cut.

The reference numeral 140 is a packing that is coupled between the flanges (111, 121, 160) to prevent the penetration of moisture.

The present invention is not limited by the one embodiment described above as long as it is a simple design change or a simple substitution of the present invention will all fall within the technical scope of the present invention.

The manhole device of the present invention configured as described above first installs the lower body 120 at the manhole construction position, and then places the packing body 140 on the upper surface of the flange 121 of the lower body 120. After mounting the flange (111) (121) fastening bolts 130 between each other to complete the assembly of the manhole body 100,

Since the side stopper 121a is formed upwardly protruding on the outer surface of the flange 121 provided at the horizontal cut portion of the lower body 120, the flange 111 formed on the lower cut surface of the upper body 110 is the side stopper 121a. Since it is guided inwardly and lowered, the upper body 110 can be seated to be exactly matched to the upper end of the lower body 120, as well as the bolt fastening holes formed in the respective flanges 111 and 121 are automatically matched. The bolt 130 fastening operation is also very easy.

At this time, the size of various internal devices, such as a flow meter, a pressure reducing valve, a dilution valve, etc., which are installed inside the manhole body 100, is large, and thus it is impossible to put it into the assembled manhole body 100 or in the assembled manhole body 100. If it is determined that the connection installation work of these internal devices is inconvenient, before assembling the upper body 110 on the upper side of the lower body 120, the flow meter, the decompression valve, the dilution valve, etc. Water level sensor 151 inside the drain pump installation part 150 formed to protrude downward from the bottom surface 120b on one side of the bottom surface 120b of the lower body 120. After installing the drain pump 152 to operate by the upper body 110 is assembled to the upper side of the lower body 120.

In this way, not only can various kinds of internal devices be installed very conveniently, but even if water is introduced into the manhole body 100, the water is accumulated in the drain pump installation unit 150, and when the water rises to an appropriate level, the water level sensor 151 At the same time as the drain pump 152 is activated and the water sucked into the water suction port is automatically discharged to the outside of the manhole body 100 through the water outlet 153 of various internal devices installed in the manhole body 100. Damage can be prevented beforehand.

When the installation of the internal devices is completed as described above, the manhole inlet formed in the upper guide part 310 after combining the upper guide part 310 to the upper side of the lower guide part 320 integrally formed on the upper surface of the upper body 110. Combining the manhole cover 200 to the (311) and then pour the soil after the abdomen can complete the construction of the manhole device of the present invention in a very simple and fast time.

When the manhole device of the present invention is used as described above, it is very convenient to replace various internal devices installed in the manhole body 100 during use.

That is, if the size of various internal devices to be replaced is larger than the inner diameter of the manhole inlet 311 to which the manhole cover 200 is coupled, the conventional manhole devices had a problem that the whole manhole device had to be replaced.

The manhole device of the present invention has a lower portion than the diameter of the upper manhole inlet 311, the guide portion 300 formed on the upper body 110, the upper surface of the manhole cover 200 is combined so that the manhole cover 200 is coupled Since the guide portion 300 is formed to be separated from the upper guide portion 310 and the lower guide portion 320 so as to have a larger diameter, the guide portion 300,

When the size of various internal devices to be replaced is slightly larger than the inner diameter of the manhole inlet 311, the upper guide part 310 having the manhole inlet 311 is disassembled from the lower guide part 320 and then the manhole inlet 311. Through the lower guide portion 320 having an inner diameter larger than the inner diameter of the manhole body 100 into the various internal devices are replaced.

When the size of the various internal devices to be replaced is much larger than the diameter of the guide part 300, the bolts fastened to the flange parts 111 and 121 formed on the lower body 120 and the upper body 110. After releasing the 130, the upper body 110 is lifted up and separated from the lower body 120, and then various internal devices are put in and then the upper body 110 is returned to the upper side of the lower body 120 after completion of replacement. After mounting the bolt 130 is fastened, it is possible to complete the replacement of a variety of internal devices with a new, very simple, fast and perfectly without having to replace the entire manhole device as in the prior art.

On the other hand, as shown in Figure 2 when the lower body 120 is composed of the bellows around the pipe connector (120a) as a center, when the various internal devices such as pre-installed flow meter, pressure reducing valve, distillation valve, etc. The manhole device of the present invention can be completed within the construction.

That is, remove the old manhole device (not shown) without dismantling various internal devices such as flow meters, pressure reducing valves, and distillation valves installed in the old manhole device.
