Embodiment Construction

[0019] The present invention will be further described below in conjunction with specific examples, but the protection scope of the present invention is not limited thereto.

[0020] like figure 1 and 2 Shown, the roof of sponge city siphon drainage of the present invention comprises gutter 9, and the sidewall of gutter 9 is provided with overflow port 11, and overflow port 11 is equipped with overflow pipe 8, and overflow pipe 8 is fixedly connected on On the outer wall of the house, the height of the water outlet of the overflow pipe 8 is 0.2-0.3m from the ground. Several siphon rainwater buckets 10 are installed in the gutter 9, and the siphon rainwater bucket 10 is connected with a pipeline 7 with a drain 4, and the drain 4 extends into an external drainage pipeline, and the pipeline 7 is provided with a second one-way valve 6 and Branch pipe 12, the branch pipe 12 is located above the second one-way valve 6, the first one-way valve 2 and the negative pressure device 3 a...

Abstract

The invention relates to a spongy urban siphoning and water-draining roof which comprises a gutter. An overflow port is formed in the side wall of the gutter, the gutter is provided with an overflow pipe, a plurality of rainwater siphoning hoppers are installed in the gutter and are connected with a pipeline with a draining port, a second one-way valve and a branch pipe are arranged on the pipeline, the branch pipe is located above the second one-way valve, a first one-way valve and a negative pressure device are installed on the branch pipe, and the negative pressure device is located at the end of the branch pipe. The negative pressure produced by wind energy and a siphoning and water-draining structure are integrated, a pressure different between the upper and lower water inlet-outlet ends of the pipeline is further increased, accordingly the water draining speed is improved, the water draining and water proofing capability is improved, and the spongy urban siphoning and water-draining roof is simple in structure, low in device cost, green, free of pollution, clean, free of energy consumption and convenient to use and convenient.

Description

technical field [0001] The invention belongs to the technical field of drainage, in particular to a roof for siphon drainage in a sponge city. Background technique [0002] The siphon phenomenon is caused by the attraction force and potential difference between liquid molecules. That is to use the pressure difference of the water column to make the water rise and then flow to the lower place. Because the water surface of the nozzle is subjected to different atmospheric pressures, the water will flow from the side with high pressure to the side with low pressure until the atmospheric pressure on both sides is equal, and the water surface in the container becomes the same height, and the water will stop flowing, and the siphon phenomenon will be used quickly. Just can pump out the water in the container. [0003] At present, the construction industry has achieved good results by using siphon structure for drainage, and the construction and installation of siphon structure is...
