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 anti-impact and wear-resistant concrete of the overflow surface and the roller compacted concrete of the dam are synchronously poured is adopted; a large amount of labor, time, materials, equipment resources and hydroelectric resources are saved, the construction period is shortened on the premise that the concrete pouring quality is guaranteed, and the construction cost is greatly reduced.
本发明公开了一种大坝溢流面常态混凝土与碾压混凝土浇筑施工方法。包括：首先进行溢流面结构钢筋和混凝土收面样架筋的绑扎、安装和焊接；将强度等级不低于抗冲耐磨混凝土的预制块绑扎在溢流面结构钢筋上之后，开始安装模板；经过冲洗的仓号开始进行大坝碾压混凝土和溢流面抗冲耐磨混凝土的浇筑施工。本发明通过优化混凝土配合比，对碾压混凝土和常态混凝土的初凝、终凝时间进行准确控制，调整碾压混凝土和常态混凝土的浇筑顺序，采用溢流面常态抗冲耐磨混凝土与大坝碾压混凝土同步浇筑进行的施工方法，节约了大量的人工、时间、材料、设备资源及水电资源，在混凝土浇筑质量有保证的前提下缩短了施工工期，大大降低了施工成本。
