AI Technical Summary

Technical Problem

The existing combined riser pipe of the long balcony building is difficult to renovate, which will affect the normal use of the water by residents. Moreover, the water quality will be polluted after the renovation, resulting in black and smelly water.

Method used

The system employs components such as a downpipe, an upper horizontal pipe, a reducing tee, a new rainwater well, and a hanger. The rainwater hopper is connected to the upper horizontal pipe via a reducing tee and a 90° elbow. A 45° elbow is installed between the downpipe and the rainwater well. The hanger is fixed to the roof beam with angle steel and expansion bolts, and the support frame is fixed to the roof with steel plates and expansion bolts to ensure stable separation of rainwater and sewage.

Benefits of technology

It has achieved a simple and efficient rainwater and sewage separation transformation, reduced construction difficulty, avoided water pollution, ensured the normal life of residents, and simplified the maintenance process.
