Surface Drainage, Whether There Are Gaps Caused Flooding In The City - Water Supply And Drainage,

Construction industry sources, the vast majority of garage design acceptance no problem:

Surface drainage, cause flooding in the city

Heavy rain even falling, Guangzhou underground parking lot of a "flooding", it means that the flooded parking lot there are gaps in the design?

Reporter learned that, although China has no specific technical specification waterproof underground parking, underground parking is underground, but part of the project has maintained a very detailed technical specifications. Specialize Water and Wastewater Professional engineer surnamed Lu said: "As long as the underground works, be it parking, delivery of the goods or even open space, building the basic requirements have to be protected it will not become a 'reservoir'."

Present, Guangzhou has put into use an underground car park, mostly follow the "underground waterproof specification" requirements, such as a variety of openings leading to the ground, set against surface water intrusion measures, entrance and exit open ditch drainage during the height of the provisions of water drainage in the section size, displacement settings.

"Set the width of some deep some of the drains, easily tens of millions for the construction work on the total cost of 100 million yuan, increasing only a little, so the design side, construction side is not worth the cost in order to save it away adventure, whether in the planning approval, building approval and construction inspection and other links, checked out all 'Mishap', so I think the developer Buzhi Yu guilty of this low-level errors (without regard to drainage facilities, etc.). "Lu Engineers said. Since the underground parking

waterproof detailed technical specifications mature, why are so many parking drowned? To many large real estate developers in a consulting firm to do consulting director told reporters: "The reason above is Shuijin Jie Jiu Cheng Man here." The director said that underground parking for vehicles to access, it is impossible the same as MTR design retaining the high level, but often through a slow upward slope to stop flooding the ground. "However, if too much ground water will diffuse through the gentle slope, straight into the parking lot. The parking lot waterproof design, only consider the rainfall in the parking lot entrance, the ground will not diffuse the water 'account' is also advance counted. Now parking Man drowned by water, can be said that public works drainage, caused by 'complications'. "The Director introduced.
