Problems solved by technology

During the construction of the roller compacted concrete dam, the temperature difference between the inside and outside of the roller compacted concrete dam and the temperature difference between the upper and lower layers will cause cracks and damage the stability and durability of the dam.
At present, almost all methods are used in the

Example Embodiment

[0024] refer to figure 2 , the present invention is a roller compacted concrete dam, the roller compacted concrete dam comprises the upstream face area 5 of the dam body, the inner area 6 of the dam body and the downstream area 7 of the dam body, and the inner area 6 of the dam body is located in the upstream face area 5 of the dam body Between the dam body and the downstream face area 7 of the dam body, the upstream face area 5 of the dam body adopts low plasticity and low heat of hydration large gradation concrete, the inner area 6 of the dam body adopts three-gradation roller compacted concrete, and the downstream face area 7 of the dam body adopts metamorphic concrete. Concrete, low plasticity and low heat of hydration large-graded concrete, three-graded roller compacted concrete and metamorphic concrete are mixed with a heat of hydration inhibitor.

[0025] The RCC dam is divided into three areas, which are divided into three areas from upstream to downstream: upstream a...

Abstract

The invention discloses a roller compacted concrete dam and a construction method thereof. The roller compacted concrete dam comprises a dam upstream positive surface area, a dam internal area and a dam downstream surface area, the dam upstream positive surface area adopts low-plasticity and low-hydration heat high graded concrete, the dam internal area adopts three graded roller compacted concrete, the dam downstream surface area adopts distorted concrete, and the dam internal area adopts a comprehensive temperature control measure. All the concretes are mixed with a hydration heat inhibitorto effectively control the maximum temperature of the dam, and cooling water tubes are not embedded in the dam, so the temperature control measure is simplified; and a thick layer compacting construction technology is adopted to avoid compactness detection of a construction warehouse surface, so the construction speed is improved. The roller compacted concrete dam is used in the field of roller compacted concrete dams.

Description

technical field [0001] The invention relates to the field of roller compacted concrete dam building, in particular to a roller compacted concrete dam and a construction method thereof. Background technique [0002] Roller compacted concrete dam is a new dam-building technology developed in recent decades. It is a concrete dam constructed by earth-rock dam technology. It not only has the characteristics of rapid construction of earth-rock dams, but also has the strength and durability of concrete dams. Unlike general concrete dams, which use a vibrator to insert and vibrate compactly, roller compacted concrete is a new concrete construction method that uses earth-rock dam construction equipment to vibrate dry hard concrete without slump. [0003] At present, the domestic RCC dam body material division is generally divided into four areas, such as figure 1 Shown: Metamorphic concrete area 1 on the upstream surface, anti-seepage area 2 of the second-level RCC upstream, third-g...
