水库普遍存在大坝坝体、坝基、坝端渗漏水等问题,混凝土护坡因其施工程序简单,使用机械器具易操作、作业面宽、可连续施工等优点,在工程加固中得到广泛应用。实践证明,混凝土护坡加固后的水库,通过对混凝土板块钻芯取样,其强度、密实度、厚度及表面回弹值都满足设计及规范要求。经检查,混凝土板块无下滑、断裂现象,水位变动区混凝土也无风浪冲袭、冰冻损坏痕迹,运行状况良好,达到了加固目的,成效明显。
There are common problems such as water leakage of dam body, dam foundation and dam end in reservoirs. Concrete revetment is widely used in engineering reinforcement due to its simple construction procedure, easy operation with mechanical equipment, wide working area and continuous construction. Practice has proved that the reinforced concrete slope protection reservoir, through the core sample of concrete slab, the strength, density, thickness and surface rebound value to meet the design and specification requirements. After examination, the concrete slab did not slide down or break down, and the concrete in the water level fluctuating zone was also free from storm waves and waves. The traces of freezing damage were in good condition and the purpose of reinforcement was achieved with obvious success.
