Deepwater pile foundation positioning and guiding structure and construction method
The invention provides a deepwater pile foundation positioning and guiding structure and a construction method. An underwater positioning support is fixedly arranged on a water bottom; a plurality of underwater guiding tubes are arranged on the underwater positioning support; a water surface positioning support is fixedly arranged on an operation water surface; a plurality of water surface guiding tubes are arranged on the water surface positioning support; a plurality of steel pile casings penetrate in the water surface guiding tubes and the underwater guiding tubes; and a water surface drilling platform is arranged on the water surface positioning support. The construction method comprises the following steps of flattening and cleaning a surface of a deepwater pile foundation during construction; sinking the underwater positioning support in place; pouring underwater fixing concrete to fix the underwater positioning support; positioning and fixing the water surface positioning support; mounting the water surface drilling platform; and mounting and positioning the steel pile casings. By the construction method, the water surface drilling platform and the steel pile casings are mounted. By the deepwater pile foundation positioning and guiding structure, the drilling precision and the pile position precision of deepwater bridge pile foundations of rivers and coastal waters can be improved, and influences of flowing water on drilling of the pile foundation are avoided.
