水电工程中的溢洪洞过流面属高速水流冲刷部位,对衬砌混凝土的表观质量及耐久性都有极高的标准及要求。结合猴子岩水电站工程实例,根据工程特点和难点,采用透水模板布粘贴在钢模台车模板板面上进场混凝土衬砌施工的方法,同时使用混凝土养护剂进行混凝土养护的试验,验证了透水模板布和混凝土养护剂在水工隧洞混凝土施工中可以取得较好效果。
The flow surface of the spillway in the hydrological electricity project will be subjected to high water flow rate and requires high resistance to the surface wearing of the concrete lining structures. This paper presents and construction technique of the pouring of the concrete lining structure of Houziyan Hydrological Electricity Project. The permeable form cloth was used inside the mobile steel forms and the concrete was cured with different additives. The work verified that the application of the permeable form cloth and the concrete additives in the poring of the wearing surfaces of the hydrological structures.
