According to the present invention, the construction of the plant is easy to produce as a field pipe, which shortens the manpower and the air, thereby dramatically reducing the cost, and made of the same material as the sewage pipe, so that a watertight connection is made without the risk of leakage, and the watertight connection is made in the future. The present invention relates to a sewer pipe joint manhole that is firmly maintained to prevent defects from occurring.

In general, a manhole is a general term for a facility that allows a person to enter and exit for maintenance and repair of various pipelines installed underground. Such a manhole is a channel for supplying various sewage, living water, and industrial water, or for various telecommunications. It is installed at a certain section and confluence point of the pipeline.

The sewer pipe is connected to the lower side of the manhole, but in order to connect the sewer pipe, it is important to prevent leakage.

If a leak occurs at the junction of the manhole and the connection pipe, there is a problem of contaminating the surrounding soil and groundwater as well as a problem in the sewage treatment if the groundwater flows back into the manhole.

The manhole facility of the prior art forms a formwork for building a manhole in the field, forms a coupling opening of a larger diameter than a sewer pipe in a part of the formwork in which the sewer pipe is coupled, and then casts concrete on the formwork while one end of the sewer pipe is connected. On-site casting method of forming sewage pipes integrally with manholes is widely used.

However, such a prior art has a problem that the construction work is very cumbersome, waste manpower and air and public affairs.

In addition, the sewage pipe made of a resin material to the concrete body is coupled, so that in winter, when the temperature decreases, the shrinkage rate of the resin material sewer pipe is larger than that of the concrete body manhole, resulting in a leak in the connection part.

Various problems have been tried in the related art in the past, but most of them are concentrated on the coupling structure of the sewer pipe to the concrete manhole.

The present invention has been made to solve the above problems,

The purpose of the present invention is the factory production, the construction of the field pipe is made easy to reduce the manpower and air, so dramatically reduce the cost, made of the same material as the sewage pipe is made of watertight connection without the risk of leakage is made in the future watertight connection The present invention provides a sewer pipe joint manhole that is firmly maintained to prevent defects.

Sewer pipe joint manhole according to the present invention for achieving the above object,

In the manhole which is provided with a manhole opening for installing a manhole cover on the upper surface and a sewer pipe is connected to the lower portion,

A base tube for forming a weight filling space at a lowermost position;

A main body tube having a tubular shape in which the connection pipe is connected to the upper part of the base pipe and is connected to the sewer pipe;

A reducer (reducer) connected to the upper body tube assembly; And

It is configured to include; and connected to the upper portion of the redundancy and is provided with a manhole opening is provided with a manhole opening,
The base pipe, the main body pipe, the redundancy and the short pipe is characterized in that it is formed of the same material as the sewer pipe (2).

Hereinafter, with reference to the accompanying drawings an embodiment of the sewer pipe joint manhole of the present invention will be described in more detail.

1 is an exploded cross-sectional view showing the configuration of an embodiment according to the present invention, FIG. 2 is a combined cross-sectional view of Figure 1, Figure 3 is a plan view of FIG.

As shown in Figures 1 to 3, the sewage pipe joint manhole 1 of the embodiment according to the present invention is provided with a manhole opening 41 for installing the manhole cover 70 on the upper surface and the sewer pipe (2) at the bottom In this connected manhole, the base tube 10 to form a weight filling space 15 in the lowest position, the connecting tube 21 is assembled and connected to the upper portion of the base tube 10 and connected to the sewer pipe (2) The tubular body tube 20 is formed of a red tube 30, the red tube 30 is assembled and connected to the upper portion of the main body tube 20 and the red tube 30 is connected to the upper assembly and the manhole opening 41 is provided ( 40), and the base tube, the main body, the redundancy and the short pipe are formed of the same material as the sewer pipe (2).

Here, the base 10 is preferably formed in the bottom surface 11, a plurality of acquisition holes (17) for preventing the injury (浮上) caused by the inundation during construction.

The short pipe 40 may be connected to a plurality of stages depending on the underground depth.

In addition, the fall safety first safety net 51 installed on the upper part of the manhole opening 41 of the short pipe 40 and the second safety net 52 which is installed on the main body pipe 20 serving as a work space and serves as a work table is provided. The second safety net 52 may be provided with a passage window 53 which can be opened and closed from above and below (see FIG. 5).

In addition, the front end of the base tube 10, the main body tube 20, the redistributor 30 and the end pipe 40 is formed in a pipe joint structure according to the type of sewage pipe.

The body pipe 20 may be connected to a plurality of stages according to the sewage pipe drop height.

In addition, each of the assembly joints between the base tube and the main body tube, between the main body tube and the redundancy, and between the redundancy and the end pipe are formed of steel and the joint rings 61a, 61b, 61c having a coupling flange formed thereon; A packing 63 is installed, and a joint ring 61d formed of steel is installed at an assembly joint of the upper end of the end pipe, and the first safety net 51 is supported by a joint ring 61d assembled at the upper end of the end pipe. The second safety net 52 is supported by a joint ring 61b installed between the main body pipe and the redoxer, and a ladder 55 supported by the joint rings 61a, 61b, 61c, and 61d is preferably installed. (See FIG. 4).

In addition, the connection pipe 21 to the main body pipe 20 may be formed in various ways such as 'T', 'Y', '十' shape.

In the drawings, reference numeral '71' is a manhole cover support member, and '73' is a site concrete for height adjustment.

It looks at the construction and working state of the sewer pipe joint manhole (1) according to the present invention having such a configuration.

In the present invention, the base tube 10, the main body tube 20, the redistributor 30 and the end pipe 40, etc. are manufactured and transported as a standard product in a factory, and construction is performed by simply assembling in the field.

The manhole construction method of the present invention connects and assembles the base tube 10 and the main body tube 20 by using the joining method according to the type of the joint ring 61 and the sewer pipe.

However, if flooding occurs during the installation work, the tubular manhole will not be seated and will float.

At this time, as the inlet hole 17 formed on the bottom surface 11 of the base tube, water is introduced into the manhole to prevent injury.

After completion of manhole positioning and backfilling to the height of the main tube, remove the water from inside and plug the stopper 13 so that water does not leak through the inlet. Placing and curing in (15) so that the main body pipe is firmly positioned even when flooding occurs.

On the other hand, the pipe joint of the sewer pipe (2) and the connecting pipe 21 is also fastened so that the watertightness is firmly maintained by using the joint method according to the type of the joint ring 61 and the sewer pipe.

Thus, since the sewage pipe 2 is connected to the connection pipe 21 formed integrally with the main body pipe 20, a rigid coupling is prevented from occurring in the manhole and the sewer pipe 2 joint, and connection is very easy. .

In addition, since the components including the connection pipe 21 are formed of the same material as the sewer pipe 2, there is no fear that a difference in expansion and contraction rate due to seasonal temperature changes occurs when the sewer pipe is connected to the sewer pipe.
