Dam overflow surface normal concrete and roller compacted concrete pouring construction method

The invention discloses a normal concrete and roller compacted concrete pouring construction method for a dam overflow surface. Comprising the following steps: firstly, binding, mounting and welding overflow surface structural reinforcements and concrete surface finishing sample frame reinforcements; after prefabricated blocks with the strength grade not lower than that of anti-impact and wear-resistant concrete are bound to overflow surface structural steel bars, a formwork is started to be installed; and pouring construction of dam roller compacted concrete and anti-impact and wear-resistant concrete on the overflow surface of the flushed warehouse number is started. According to the construction method, the concrete mixing proportion is optimized, the initial setting time and the final setting time of roller compacted concrete and normal concrete are accurately controlled, the pouring sequence of the roller compacted concrete and the normal concrete is adjusted, and the construction method that the normal
