Circulating water forebay construction supporting method for power plant

The invention discloses a circulating water forebay construction supporting method for a power plant, and particularly relates to the technical field of construction supporting. 2, auxiliary construction of a three-shaft mixing pile concrete pile foundation; and 3, high-pressure jet grouting pile construction sealing. According to the construction method, the three-axis cement soil mixing piles, the high-pressure jet grouting piles and the steel sheet piles are combined at the water inlet forebay of the circulating water pump house, the problem of high water permeability and water stop of the coastal sandy stratum is solved, the construction safety is guaranteed, the construction efficiency is improved, and the effect of completely isolating seawater is achieved when the construction method is used under the coastal high-permeability sandy stratum condition; the construction period is short, no pollution is caused, the cost is low, the vibration noise is low in the construction process, the environment is not
