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 polluted, and the influence on surrounding buildings is small.
本发明公开一种电厂用循环水前池施工支护方法，具体涉及施工支护技术领域，包括步骤一、区域灌注桩施工；步骤二、辅助施工三轴搅拌桩混凝土桩基，步骤三、高压旋喷桩施工密封。本发明在循环水泵房进水前池处采用三轴水泥土搅拌桩、高压旋喷桩和钢板桩组合的施工方法解决了沿海沙质地层高透水止水难题，保证了施工安全、提高施工效率，在沿海高透水沙质地层条件下使用，达到完全将海水隔离的效果，施工工期短，无公害，成本低，施工过程中振动噪声低，不污染环境，对周围建筑影响小。
