And a slag blocking device is arranged between the reservoir and the corresponding water collecting channel.

The slag blocking device further comprises a connecting pipeline for communicating the water collecting ditch with the reservoir; the connecting pipeline is provided with a sand settling and dirt blocking pool for blocking slag; the sand setting trash-blocking tank is internally provided with a trash-blocking filter screen.

Further, a control gate valve is arranged on the second pipeline.

The utility model has the advantages that: 1. the rainwater collecting ditch is arranged on the contour line, so that rainwater falling on a mountain slope can be collected to the maximum degree and can be converged into the water storage tank, rainwater can be collected in a mountain area with relatively short water resources, and the probability of mountain flood outbreak can be reduced in an area where mountain floods are prone to outbreak;

2. the slag blocking structure is arranged between the water collecting ditch and the water storage tank, so that deposited sand and waste slag in collected rainwater can be prevented from entering the water storage tank, the cleanness of water in the water storage tank is ensured, and the collected rainwater can be conveniently recycled;

3. through set up the control gate valve on the second pipeline, be convenient for control the water circulation between the adjacent cistern, constitute a slice irrigated area, improve irrigation assurance rate and moisture productivity ratio.

The utility model discloses a by the conversion of "control flood" to "management flood", utilize "rainy early in summer", collect the rainwater through the collection rain surface, the collection holds to the cistern, plays and effectively blocks the mountain torrent, stores the rain torrent of collection on the hillside, to improving aquatic ecological environment, prevent that soil erosion and water loss from having more important positive effect.
