Research on Construction Technology of Deep Water Diagonal Rock Pile Foundation in Environmentally Sensitive Areas
In order to ensure the quality and protect the environment of pile foundation construction of bridge engineering under the geological conditions of deep-water inclined rock riverbed in environmentally sensitive areas,and to optimize the construction technology of bored piles reasonably,this paper takes the pile foundation construction of a railway bridge as the research object.Through the use of rotary drilling and mud reverse circulation system based on the principle of air lift reverse circulation,the results are analyzed by means of engineering practice effect and water quality monitor,and the research on rotary drilling construction and mud hole circulation system of deep-water inclined rock pile foundation in environmentally sensitive areas is carried out.The results show that the above methods can effectively guarantee the construction quality of pile foundation under the geological conditions of deep-water inclined rock riverbed and reduce the impact on the environment.
