Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The utility model provides a baffling open channel for treating and controlling rainwater runoff in a building district, which comprises an inlet channel 1, an overflow baffle 2, a baffling component 3, a sand collecting tank 4, an end cover 5 and a plurality of inlet pipes 6, wherein the inlet channel 1 is provided with a first water inlet and a first water outlet; the preferred inlet channel 1 is a straight channel.

The overflow baffle 2 is arranged in the water inlet channel 1 relatively in the first water inlet, and the top height of the overflow baffle 2 is lower than that of the water inlet channel 1.

Baffling subassembly 3 includes a plurality of baffling canals 31, a plurality of interception net 32, baffling canal 31 and the perpendicular and a plurality of baffling canal 31 end to end connection in proper order of inlet canal, the end of intaking that is located first baffling canal 31 is linked together with inlet canal 1, and the intercommunication department be located overflow baffle 2 with between the first water inlet, the outlet end that is located the baffling canal 31 of tail position is linked together with inlet canal 1, and the intercommunication department be located overflow baffle 2 with between the first delivery port, a row of husky mouth has been seted up to the bottom of each baffling canal 31.

The interception nets 32 are arranged corresponding to the deflection channels 31 one by one, and the interception nets 32 are arranged in the corresponding deflection channels 31 and arranged between the sand discharge port and the water outlet end of the deflection channels 31;

preferably, a slot is formed inward at the top of each baffle channel 31, the bottom of the slot is flush with the inside of the bottom of the baffle channel 31, and the interception net 32 is slidably inserted into the slot.
