Description

The improved manhole for construction}

The present invention relates to an improved manhole for building, and the septic, living sewage and rainwater of the septic tank generated in the building flows into the manhole to block odor emission when drainage is made, and at the time of construction according to the location of the sewage pipe and living sewage pipe The height can be adjusted.

Manholes are divided into road manholes and building manholes.

Road manholes are provided with manholes at one point of sewer pipes, and rainwater can be introduced into the upper part, and the manholes can be easily cleaned of sediments and debris from manholes. A passage is provided and rainwater is filtered out of the strainer to allow inflow and discharge and to clean sediments and debris.

Here, if the manhole is constructed together with the inlet of the septic tank and the living sewage inlet, even if the septic passage and the manhole of the septic tank are linked, the manhole does not occur even if the odor of the manhole flows back into the septic tank. If the odor of the manhole flows back into the inflow passage of domestic sewage, the odor is released into the building, which causes obstacles to life.

As a means of eliminating this, if the manhole for septic tank and manhole for living sewage are installed separately and the manhole of living sewage is equipped with a countermeasure against bad smell, individual manholes are constructed, resulting in complicated construction and difficult cleaning and maintenance of manholes. There is this.

In addition, the manhole equipped with the septic tank inlet and living sewage inlet has not been adjusted in the position of the septic tank and the domestic sewer inlet.

Therefore, the present invention solves the conventional drawbacks, while the manhole is provided with a sewage inlet and a living sewage inlet at the same time, the manhole is partitioned into partition plates to separate the septic tank sewage inflow passage and the living sewage inflow passage, and the living sewage inlet and the partition plate. The purpose of the present invention is to provide an improved manhole for the construction by providing an opening and closing plug in the drain passage to block odor and to adjust the positions of the septic inlet and the living sewage inlet of the septic tank to simplify the construction.
