Abstract
The invention discloses a concrete dam hole construction method, and belongs to the technical field of concrete dam construction. The method comprises the following steps that T1, a dam hole prefabricated part is manufactured in advance; t2, a roller compacted concrete area A is constructed, and then the dam hole prefabricated part is installed on the roller compacted concrete area A; t3, a roller compacted concrete area B is constructed, meanwhile, metamorphic concrete is poured into a gap between the roller compacted concrete area B and the dam hole prefabricated part, and the metamorphic concrete between the roller compacted concrete area B and the dam hole prefabricated part rises synchronously; t4, deformed concrete is poured on the upper side of the dam hole prefabricated part; (T5) a roller compacted concrete area C is constructed; and T6, a roller compacted concrete area D is constructed. In the construction process of the roller compacted concrete dam, only the dam hole prefabricated part needs to be hoisted and installed to the designed position on site, the construction technology of the roller compacted concrete dam is simplified, meanwhile, the rising speed of dam roller compacted concrete is remarkably increased, and the overall construction period is shortened.
