摘　　要：深圳市东江水源工程输水建筑物需每年进行停水检修,但历年停水检修的排水工作存在费用高、效率低、时间长等问题。为了确保供水的稳定性及安全性,亟须对该工程输水建筑物检修排水设施进行改造。文章针对东江水源工程检修过程中存在的问题进行深入分析,并结合工程实际情况,对东江压力管段排污阀井、压力箱涵及沿线排污阀井等排水设施制订改造方案。为了验证该方案的可行性,对其改造效果展开分析。结果显示,该方案实施后能有效缩短排水工作时间,提前进行停水检修工作,且投资相对较小,综合效益显著。The water conveyance structure in Dongjiang water source engineering in Shenzhen needs to be overhauled with water outrage every year,but there are some problems such as high cost,low efficiency and long time in the drainage work in overhaul with water outrage over the years.In order to ensure the stability and safety of water supply,it is urgent to reconstruct the overhaul and drainage facilities of the water conveyance structure in the engineering.This paper makes an in-depth analysis of the problems existing in the overhaul process of the Dongjiang water source engineering,and combines the actual situation of the engineering to formulate a reconstruction scheme for the drainage facilities such as the blowdown valve chamber,the pressure box culvert in Dongjiang pressure pipe section and the blowdown valve chamber along the line.In order to verify the feasibility of the scheme,the reconstruction effect is analyzed.The results show that after the implementation of the scheme,the drainage working time can be effectively shortened,the overhaul work with water outrage can be carried outin advance, the investment is relatively small, and thecomprehensive benefit is remarkable.
