西边坑河涌整治工程的关键技术设计

Some key technical considerations in design of Xibiankeng watercourse reformulation

针对工程所在的自然地理环境,在分析洪水和暴雨流量的基础上,给出了水面线、河涌纵横断面的设计方法.初步实践证明,防洪排涝效果较好,但施工期间的废气、废水、废渣将会对环境产生一定的影响.

A method for the design of the flow profile and vertical and cross sections of the watercourse was given in accordance with the natural geographical environment of the project on the basis of analysis of the flood and rainstorm flow rate. Preliminary practice has proved that the effect of flood control and drainage is rather good. However, the waste gas, water and solids produced during construction will exert influence on the environment.
