The present invention maintains the precision of the surfaces in contact with each other constituting the circular manhole by changing the manufacturing method, and inserts a water-expandable rubber resin material into the groove part installed therein to increase the watertightness to maximize the effect of the circular manhole. -TYPE Circular manholes.

In general, as shown in FIG. 1, the manhole includes a cylindrical body and an inlet pipe and an outlet pipe which are sewage pipes connected to the lower part of the body.

In order to connect the inlet and outlet pipes, the wall thickness is thinned in three directions or two directions so that the holes can be easily drilled at the construction site, or the holes are made in advance in the manhole to connect the sewer pipes at the site or to secure watertightness. In some cases, the means tube is inserted into the wall to be integrated.

The method of inserting the local means pipe is avoided due to the complicated manufacturing process, and the construction by the two methods described above is predominant.

However, in this case, it should be precisely installed between the hole and the sewer pipe so that there is no leakage. Actually, it is not so precisely constructed, and it is difficult to check after construction, and even though leakage occurs, it is not a problem.

Therefore, since manpower and time are required for the production of the local means pipe, it is difficult to control the quality at the site and cause the increase of manhole construction cost.

In addition, the lower sphere, the vertical sphere, and the slab constituting the main body, as shown in Figure 2, assembling the formwork used to directly mold the concrete manhole into a plurality of panels to stiffen to pour concrete therein and then to the panel Complete by removing it.

In particular, the lower sphere is the base of the circular manhole, which is a concrete structure in which a bottom plate is made in advance and cured, and a wall is formed thereon.

In this case, as well as the lower sphere, the vertical sphere, the slab is mostly produced on the uneven floor of the construction site, so the two or one side of the connection surface is not precisely horizontal, especially as the opening of the formwork assembled as shown in the drawing When the concrete is poured, it is hardened into an uneven shape due to the viscosity and composition of the concrete.

As the upper and lower spheres or some of the connection part surface is not made smoothly, a lot of gaps are generated in the connection part with the lower or vertical spheres, causing the body to be distorted or leaks, which is a cause of the poor construction.

As more than 90% of domestically used manholes are made in this way, the auditor's audit showed that one site was constructed poorly on average 27 meters of 76000km sewage pipes nationwide, and even if sewage treatment plant is installed due to leakage of wastewater, Destruction continues, and on the other hand, rainwater or groundwater seeps into the sewer pipes and exceeds the limits of the sewage treatment capacity, so that the national budget is being saved.
