The invention relates to a bored concrete pile using an ultra-high performance concrete protective tube and a fabricating and constructing method thereof. The bored concrete pile comprises a pile body vertically inserted into deep water, the pile body is sleeved with the protective tube formed by ultra-high performance concrete, a rebar cage is arranged in the pile body, the upper end of the protective tube is positioned above the water surface, the bottom of the protective tube is located below the mud surface of a riverbed, and the pile body and the protective tube are subjected to one-time-concreting shaping. During fabricating and constructing, (1) the protective tube is prefabricated by the ultra-high performance concrete according to design requirements; (2) the protective tube is hoisted by a machine and arranged on the designed position of the pile body to enable the center line of the protective tube to coincide with the center line of the pile body; (3) the lower end of the protective tube is submerged into the riverbed by adopting a pile sinking method to enable the bottom of the protective tube to reach the designed elevation or the position below 2m of the maximum scouring depth of the riverbed; (4) the rebar cage is inserted into the protective tube, and common concrete is poured into the rebar cage to enable the protective tube to wrap the pile body. The bored concrete pile is simple in structure, the capacity of a pile foundation resisting river scouring and impact of sand and stone in water is effectively enhanced, and the service life of a bridge is prolonged.
