Tandem type pre-tensioning method double-T-beam prefabricated pipe pile force transmission device and construction method

The invention belongs to the technical field of civil engineering, and particularly relates to a tandem type pre-tensioning method double-T-beam prefabricated pipe pile force transmission device and a construction method. According to the tandem type pre-tensioning method double-T-beam prefabricated tubular pile force transmission device and the construction method, by arranging the end cross beams, the force transmission columns and the force column supporting mechanisms, when double-T-beam tensioning construction is conducted, the prefabricated tubular piles capable of being repeatedly used serve as a tensioning force transmission system, the structural size of the tensioning end of the double-T-beam and the damage depth of an original hardened base layer are reduced, and the construction efficiency is improved. The invention has the advantages of simple structure, environmental protection and high efficiency, only needs to input recyclable prefabricated tubular piles, force column supporting mechanisms and
