Concentrative discharge structure for underground rainwater of townhouse

Abstract

The invention discloses a concentrative discharge structure for underground rainwater of a townhouse, and belongs to the technical field of rainwater discharge. According to the technical scheme adopted by the invention, the key point is that the concentrative discharge structure comprises a rainwater well arranged on the bottom of a townhouse green belt and a water drainage tube which is pre-embedded into an underground parking garage or a sunken garden and communicates with the rainwater well; the upper-end opening of the water drainage tube is flush to the ground; the section of the water drainage tube is rectangular; a rainwater grate is arranged at the upper-end opening of the water drainage tube; the lower end of the rainwater grate is equipped with a lifting rod which extends into the water drainage tube and is controlled by a wireless control module; the bottom of the lifting rod is equipped with a spoon net which slips inside the water drainage tube; and the outer wall of thespoon net is fitted to the inner wall of the water drainage tube. The concentrative discharge structure has the advantages of conveniently getting out impurities in the water drainage tube, and improving discharge efficiency of underground rainwater.

Description

technical field [0001] The invention belongs to the technical field of rainwater drainage, and more specifically relates to an underground rainwater centralized drainage structure for townhouses. Background technique [0002] Townhouses originated in the 1940s and 1950s during the New Town period in England, and they are common in Europe and the United States. Townhouses are generally composed of several or more than a dozen low-rise residential buildings less than 5 floors connected in parallel. Each building has an area of ​​about 150-200 square meters, and has its own independent garden at the front and back, but the area of ​​the garden generally does not exceed 50 square meters. In addition, there are special parking spaces or underground parking garages. [0003] For the underground parking garage or sunken courtyard of existing villas, the rainwater discharge method is generally to open a rainwater well at the bottom of the green belt of each villa, and to pre-bury t...

Problems solved by technology

[0004] However, the debris on the underground parking garage or sunken garden, such as grass powder, paper scraps, cigarette butts, dust, etc., can enter the drain pipe, which is easy to cause blockage of the drain pipe. Remove the sundries in the drainpipe, or even replace the entire drainpipe, but the process of manually removing the sundries in the drainpipe is cumbersome, which affects the drainage efficiency of underground rainwater
