Description

Integrated management manhole for pipe line

The present invention relates to an integrated management manhole for a pipeline, and more particularly, to an integrated management manhole for a pipeline, which is applied as an upper slab and a lower slab, which are divided into a plurality of sections and closely adhered to each other, The installation period can be shortened remarkably. Also, since the equipment manhole lid and the maintenance manhole lid are provided, the equipment can be easily installed and installed in the internal space, and the equipment installed in the internal space can be easily maintained, To an integrated management manhole for a pipeline so that forced discharge can be easily performed.

In general, when we look at the supply route of water that we use, we collect the river water at the water intake station and send it to the water purification plant to purify the water in the water intake plant. The purified water in the water purification plant is installed on the mountain, The water sent to the pumping station is sent to the reservoir near each building with constant potential energy.

In other words, in the case of Seoul waterworks, more than 48% of the area is composed of highlands and hills with high altitude difference from flat land. Therefore, there are many areas where water supply is impossible from the water supply pressure from the water purification plant. It operates the pumping station.
