Point selection, drilling, drilling, lifting... On March 27, 2023, the Zhonghe Reservoir Project in Jinzhai County, undertaken by the Hefei Branch of China Aneng First Bureau, successfully extracted a length of 20.25 meters and The 200 mm diameter roller compacted concrete core sample indicates that the quality and technology of the dam construction have reached the industry-leading level.

Concrete coring is an important means of testing the quality of concrete construction. Through coring, the quality of concrete pouring can be observed, the uniformity of concrete pouring can be verified, and the thickness of the rolling layer, compaction and interlayer bonding can be correctly judged and checked. During the concrete construction of the Zhonghe Reservoir dam, the project department strictly followed the design specifications, conscientiously implemented various quality control measures, continuously explored and summarized, improved the construction technology, and realized real-time monitoring of the entire process of concrete warehousing, pouring, and maintenance. monitor. According to the observation of the core sample taken out, its appearance is smooth and smooth, the aggregate distribution is even, the structure is dense, the interlayer bonding is good, and the integrity is high, which objectively reflects the construction quality of the RCC of the Zhonghe Reservoir Dam and the level of coring technology.

length measurement

The roller compacted concrete gravity dam of Zhonghe Reservoir in Jinzhai County is located in Jinzhai County, Anhui Province. The largest dam is 52.5 meters high and 212.5 meters long. The total storage capacity of the reservoir is 7.06 million cubic meters. It governs the rural drinking water safety of 60,000 people in Gubei Town and Huaishuwan Township, develops an irrigation area of 4,000 mu, and provides ecological supplementary water sources for the Wangjia River in Gubei Town.

The successful extraction of core samples this time fully demonstrates the leading level of China Aneng No. 1 Bureau in the field of domestic concrete coring, greatly boosts the morale of all staff in the project department, and improves the construction image of the project department.Editor / He Yurong
