- 摘要:
- 以我國北方某城市的典型易澇區(qū)域整治項目為例，介紹了系統(tǒng)化方案的編制方法和實施效果。首先從匯水分區(qū)的尺度分析內(nèi)澇積水成因，然后根據(jù)目標(biāo)要求制定匯水分區(qū)優(yōu)化、源頭減排系統(tǒng)改造、排水管渠系統(tǒng)改造、排澇除險系統(tǒng)建設(shè)相結(jié)合的系統(tǒng)化方案，并建立排水模型對方案實施效果進行量化評估。在案例項目中，通過局部排水管線調(diào)整將匯水分區(qū)范圍減少約24%；通過小區(qū)和道路海綿化改造，實現(xiàn)了年徑流總量控制率不小于70%、年SS削減率不小于60%的目標(biāo)要求，同時顯著降低了徑流峰值；通過雨水管渠提標(biāo)改造將管渠排放標(biāo)準(zhǔn)提高到2年一遇；通過在人行道設(shè)置多處超標(biāo)徑流入河（綠地）通道，提高了排澇能力和調(diào)蓄能力，達到了30年一遇內(nèi)澇防治標(biāo)準(zhǔn)。該系統(tǒng)化方案通過雨水徑流的合理組織和排水防澇設(shè)施系統(tǒng)改造建設(shè)，在消除城市內(nèi)澇問題的同時，實現(xiàn)了徑流總量控制、徑流污染控制、景觀提升和地下水涵養(yǎng)等多重目標(biāo)，可為其他城市提供參考和借鑒。
- Abstract:
- The preparation method and implementation effect of a systematic plan of a typical waterlogging area remediation project of a northern city in China were introduced. The causes of waterlogging from the scale of the catchment zone were firstly analyzed. Then, a systematic plan combining the optimization of water catchment zoning, the reconstruction of the source emission reduction system, the reconstruction of the drainage pipe and canal system, and the construction of the drainage system were formulated according to the objectives and requirements, and a drainage model was established to quantitatively evaluate the implementation effect of the plan. In the case project, the catchment area was reduced by about 24% through local drainage pipeline adjustment. The target requirements of annual total runoff control rate of no less than 70% and annual SS reduction rate of no less than 60% were achieved through the sponge transformation of residential quarters and roads, and the runoff peak value was significantly reduced. The drainage standard of pipe and channel was raised to 2 year return period through the improvement of rainwater pipe and channel. The drainage capacity and storage capacity were improved by setting channels where excessive runoff flowed into the river (greenbelt) in many places along the sidewalk, and the waterlogging prevention reached 30 year return period standard. Through the reasonable organization of runoff and the reconstruction of drainage and waterlogging prevention facilities, this systematic plan not only eliminated the urban waterlogging problem, but also achieved multiple goals such as total runoff control, runoff pollution control, landscape improvement and groundwater conservation, which could provide reference to other cities.
