Embodiment 4:

Roof drain:

Roof drain is the water inlet of entire Stormwater Drainage System, and main function is maximum excretion rain, snow-broth；To into Water has rectification, guide functions, makes water flow stationary, to reduce the aeration of system；Have the function of intercepting coarse impurities simultaneously.

Connecting tube:

Connect the short tube of roof drain and column pipe.

Column pipe:

Column pipe is connect with connecting tube and rain leader downspout, sees indoor rainwater system figure, for some important workshops, no Indoor inspection shaft is allowed to emit water, when buried transverse tube cannot be set, it is necessary to which column pipe is set.

Standpipe:

The rainwater for receiving roof drain or column pipe, connect with discharge pipe.

Buried transverse tube:

Closed system generally uses column pipe is aerial to drain into outdoor, does not set buried transverse tube；Open system, interior are equipped with inspection Cha Jing, the pipe between inspection shaft are buried-pipe laying.

Inspection shaft:

Some sundries on roof are usually rushed in pipeline by rainwater, to be arranged between indoor rainwater underground pipe convenient for clear and coherent Inspection shaft.It is should be noted that when design to prevent inspection shaft from emitting water, checks that well depth cannot be less than 0.7m.Inspection shaft inner connecting tube should be adopted It is flushed with tube top, and water flow corner cannot be less than 135o in plane.
