Construction method for semi-integral jointless bridge structure adaptive to soft soil foundation

The invention discloses a construction method for a semi-integral jointless bridge structure adaptive to a soft soil foundation. The construction method for the semi-integral jointless bridge structure adaptive to the soft soil foundation comprises the following steps of first, erecting a precast beam, arranging a permanent support and a temporary cushion block under the precast beam; arranging the temporary cushion block at the end part of the precast beam to support the precast beam; and then binding a reinforcement in a beam-end cast-in-situ section, embedding an embedded part of a tension-compression combined member in the beam-end cast-in-situ section, and pouring the beam-end cast-in-situ section, which is positioned above the permanent support, at the end part of the precast beam; and finally, pouring a pavement; mounting a tensile top plate, on which a PBL shear resistant perforated plate is welded, a perforated reinforcement, a reinforcing reinforcement and a pavement reinforcement above the embedded part of the tension-compression combined member; and pouring a concrete leveling course and an asphalt concrete surface course. According to the construction method for the semi-integral jointless bridge structure adaptive to the soft soil foundation, the mounting accuracy is greatly improved, tension-compression combined expected effect can be synchronously achieved, and the mounting and pouring angles of a tension-compression rod can be adjusted according to on-the-spot erecting situations to ensure that a tension rod is closely attached to the beam top and a compression rod is closely attached to the beam end.
