[0051] The specific implementation of the invention will be further described below in conjunction with the drawings.
[0052] A construction method of a deep-water steel trestle bridge without covering layer, including the following steps:
[0053] (1) Construction of steel pipe pile foundation: The steel pipe pile 1 is installed on the river bed 11 in the form of a single row of piles, and the pile top elevation is higher than the five-year flood level. If the new water conservancy project is added, the flood level has been affected in the past years. The hydrological station should provide the annual flood level data after the newly added water conservancy project, and comprehensively compare the cost and the stability factors of the steel trestle; each steel pipe pile 1 is equipped with a settlement observation point for monitoring the station. The settlement of the steel pipe pile 1; wherein the installation method of the steel pipe pile 1 includes the following steps:
