The invention relates to a rotation V-type T-structure bridge
pier and a construction thereof. When an included angle formed between a line and an existing busy
trunk line through vertical crossing is smaller, cross-hole arrangement of a bridge is more difficult. The bridge
pier is constructed on one side of the existing
trunk line, and comprises a
pile foundation, a supporting platform,
pier arms and a cover beam from bottom to top, wherein the supporting platform is divided into a lower rotary table and an upper rotary table from bottom to top; a rotary spherical hinge is arranged between the upper rotary table and the lower rotary table; during line operation
skylight time, the upper rotary table and the structure rotate to a designed position by taking the rotary spherical hinge as the center, concrete on the outer side of the rotary spherical hinge is poured to form a
solid stage, and the lower rotary table and the upper rotary table are fixedly connected together to complete construction. Due to the adoption of a rotation V-type T-structure scheme, the construction only needs to be performed on one side of the existing line, requirements for roads and construction sites on the other side are reduced, the conditions that houses on two sides of the existing line in an
urban area are dense and are difficult to remove are facilitated, the removal cost is greatly reduced, and the construction period is guaranteed; meanwhile, due to the adoption of rotation construction, the influence on operation of the existing line is minimized.
