中型水库除险加固涉水作业的质量安全控制

Quality and Safety Control of Water Related Operations for Risk Removal and Reinforcement of Medium-sized Reservoirs

当前随着水库修建的饱和,既有水库的加固除险工程占比越来越高,对水库加固除险工程的质量控制非常重要,事关水库的加固效果的运营安全稳定的年限,研究探索水库加固除险施工质量控制体系非常重要。针对白沙河水库的加固除险施工,基于其受供水和调洪的影响下合理排布施工期。对水库的主体工程加固和混凝土支护结构的施工关键工艺提出了具体方案,并重点对混凝土和新建输水隧洞和主坝防渗墙的施工质量提出了控制措施,为白沙河水库在调洪供水周期下的顺利高质量施工提供了依据。

With the saturation of reservoir construction,the proportion of risk removal and reinforcement projects for existing reservoirs is increasing.The quality control of reservoir reinforcement engineering is very important,which is related to the safe and stable operation of reservoir.It is very important to study and explore the quality control system for reservoir reinforcement construction.For the reinforcement construction of Baishahe Reservoir,this paper reasonably arranges the construction period based on the influence of water supply and flood regulation.At the same time,specific plans have been proposed for the key construction techniques of the reinforcement of reservoir main projectand concrete support structure.And key control measures have been proposed for the construction quality of concrete,new water conveyance tunnels,and main dam anti-seepage walls,providing a basis for the smooth and high-quality construction of Baishahe Reservoir during the flood regulation and water supply cycle.
