Roller compacted concrete dam prefabricated stairwell
The invention discloses a roller compacted concrete dam prefabricated stairwell. The roller compacted concrete dam prefabricated stairwell comprises a plurality of stairwell subsections which are sequentially stacked from bottom to top. Each stairwell subsection comprises a square prefabricated shaft and two sections of prefabricated step plates. The prefabricated step plates are arranged inside the prefabricated shafts in a staggered mode and are connected end to end. Two brackets matched with the corresponding prefabricated step plates are arranged on the inner wall of each prefabricated shaft. The top ends of the prefabricated step plates are arranged on the brackets and fixed through foundation bolts. A convex edge is arranged at the top end of each prefabricated shaft, and a concave groove matched with the corresponding convex edge is formed in the bottom end of each prefabricated shaft. According to the roller compacted concrete dam prefabricated stairwell, the procedures that cast-in-situ of stairwell vertical formworks inside a roller compacted concrete dam is conducted, reinforcement assembling is carried out and joint bars need to be reserved on stairway plates for conducting second-phase pouring are omitted, so the construction period can be shortened, and the project investment can be reduced.
