stop the ground or road

ZhangXiaoXin said, this city prepare for several key areas, key road drainage system planning and research, and gradually raise these areas drainage system standards and ability, safeguards these key areas and key areas to be able smoothly drainage. Met rainstorm According to information, these key areas and roads, including tiananmen square, financial street, CBD, still include important areas such as Tibet, jing jing) expressway, and ring highway and the wilderness and the auxiliary, road.

ZhangXiaoXin said, in a period of time, drainage expansion, will and flood season take emergency measures parallel use. "Can take engineering measures is best, but it needs time."

According to the reporter that information to show, at present this municipality in some local area in the finished drainage is not smooth. For new district and general finished, can through increasing pipe diameter, rain shunt intercepting wait for means to undertake reform. And in the densely populated areas, enabling community rain water loss.ponds, increase the greening area, into permeable square brick wait for means, can alleviate rainwater flow of urban drainage system pressure.

Local standards compiled is going to carry out

Public data showed that in recent years, this city successive happen one hour rainfall than 70 mm of local extreme rainfall weather. While in regional scope, only tiananmen square and the Olympic park public area network to meet a drainage standard hours 56 millimeter, also is 5 years in a extreme weather, Parts of the drainage pumping station can achieve cope with 2 or 3 years in a extreme weather requirements; While many of the trunk road drainage capacity can reach an hour 36 millimeter, namely 1 year in a extreme weather standards.

In urban rainwater drainage system planning and design standard research work on the expert's demonstration, through drainage system of the Beijing local standards for construction work, also is imminent, and this work usually takes two years.

"We also hope to advance rainwater drainage system planning and design as soon as local standards compilation work, in order to guide the construction of Beijing rainwater drainage system and solving rain water problem." ZhangXiaoXin said.
