Embodiment 1
[0018] The concrete anti-cracking method of the flood discharge tunnel of the hydropower station according to the present invention, its construction steps are:
[0019] (1) The concrete of the unpressured section of the flood discharge tunnel is divided into blocks according to the length of 15m, and the part of the aerated sill where the structure changes is divided into blocks according to the length of 18m. The pouring height of the first and second floors of the side walls is 4.5m, the third and fourth floors are poured at a height of 3m to 1m below the arch line, and the top arch is used as the first floor construction. Seam penetration and copper water stop treatment;
[0020] (2) The concrete is proportioned according to the standard ratio of cement, sand aggregate, admixture, admixture and mixing water, and the alkali activity test of the concrete aggregate is carried out in due course;
[0021] (3) When carrying out the concrete mix construction of the anti-impact and
