Hekou Village Dam Completion Detection Mode Research And Exploration

Intercept River Dam water to raise the water level in the river channels and adjust the flow with water retaining structures, to ensure the quality of construction and safe operation of the dam, to explore new methods of detection and evaluation system has important practical engineering significance. Based on the investigation on the basis of current research, to explore the detection mode before the completion and acceptance of hydraulic dam, concrete dam of the currently used detection methods are analyzed, and the Hekou village of Jiyuan in Henan dam to detect objects on the design specifications of the dam were detected(in non-destructive testing based), research can provide technical support for the completion and acceptance of reservoir dams.Village in the town of reservoir is located in Kejing Town of Jiyuan City territory Qinhe river in the last paragraph canyon at the exit, it holds the basin area of 9223 square kilometers, occupy river dawen river basin area, the Yellow River Xiaolangdi to Hua Yuan Kou without engineering control interval area of 68.2%, 68.2%.The reservoir spillway of hydraulic structures including concrete face rockfill dam, flood discharge, and water power generation system, belong to the big(Ⅱ) water conservancy hub project, flood control standard is 500, checking standard is 2000, capacity of 317 million m3.Type reservoir dam with concrete face rockfill dam dam, dam, 530.0 meters high, 122.5 meters long, dam crest elevation of 288.5 meters, project total investment 2.775 billion yuan, the project total duration 60 months. The main contents of this article:(1) put forward the main content of the dam concrete appearance quality detection, summarized the concrete appearance quality testing method and evaluation index.(2) describes the mechanical properties of the concrete dam physical detection method is proposed based on the physical and mechanical properties testing should pay attention to the problem, analyze the specific factors of various detection methods of test results.(3) This paper expounds the principles and methods of dam concrete durability testing, analyzes the advantages and disadvantages of all kinds of durability test method.(4) By detecting hekou village dam concrete detection method proposed was the practical application of research.
