Research on application of cofferdam technology in diversion of water conservancy and hydropower construction
It is an important part of the construction of cofferdam to make use of cascade drilling technology for curtain grouting.This paper summarizes the design of concrete construction parameters by studying the fluid characteristics in curtain grouting.The application of specific technology in diversion cofferdam is sorted out by taking specific projects as cases.From the perspective of quality control,the influence factors of diffusion radius,water-cement ratio and pulp consumption are analyzed,and the quality control countermeasures are given based on the analysis results.It is hoped that the research of this paper can provide help for the subsequent construction.
