混凝土防洪堤坝防渗墙加固施工技术

Construction Technology of Seepage Wall of Concrete Flood Control Dam

常规的堤坝防渗墙加固施工所设定的承压槽段一般是独立的,具有一定的稳定性,但是承压效果不佳,导致抗拉强度下降。文中对混凝土防洪堤坝防渗墙加固施工技术进行分析及验证。测试结果表明,针对4个防渗墙的测定,最终得出的抗压强度较好地控制在了1.2MPa以上,表明在实际的加固处理过程中,墙体内质结构的承载能力得到了加强,具有较高的应用价值。

The pressure bearing groove section set by the conventional dam cutoff wall reinforcement construction is generally independent and has a certain stability, but the pressure bearing effect is poor, leading to the decline of tensile strength. In this paper, the construction technology of strengthening the cutoff wall of concrete flood control dam is analyzed and verified. The test results show that the ultimate compressive strength of the four cut-off walls is better controlled at more than 1.2MPa, indicating that the bearing capacity of the internal structure of the wall has been strengthened in the actual reinforcement process, which has practical application value.
