Abstract

The invention discloses a T-shaped groove-based socket connection structure and a construction method thereof, wherein the construction method includes the steps of: a. cast-in-place or prefabricated caps, so that the upper port of the caps forms a T-shaped longitudinal section; For the notch, the first shear reinforcement protruding upward is pre-embedded on the bottom wall of the cap corresponding to the large opening, and the first tensile steel bar protruding toward the center of the large opening is pre-embedded on the side wall of the cap corresponding to the large opening, prefabricated for inserting For the pier column installed in the notch, the second tensile steel bar protruding to the outside of the pier column is pre-embedded on the side of the pier column; b. Lay a grouting material leveling layer on the bottom wall of the cap corresponding to the small opening, insert the pier column Erection in the notch; c, adjust the plane coordinates, elevation and verticality of the pier column; d, connect the first tensile steel bar and the second tensile steel bar through the tensile connecting steel bar; e, pour concrete in the notch, which is based on The T-slot socket connection structure and its construction method aim to solve the technical problems of the existing socket connection structure with poor durability and anti-seismic performance.

Description

technical field [0001] The invention relates to the technical field of socket-type connection structures, in particular to a socket-type connection structure based on a T-shaped groove and a construction method thereof. Background technique [0002] For the connection between the lower pier body and the cap of the fabricated bridge, there are certain problems in the existing main connection technologies: ① Reinforcement welding or lap joint and wet joint connection: mechanical properties are often similar to traditional cast-in-place concrete piers, but wet The joints will increase the construction time and require more maintenance time; ②The post-tensioned prestressed tendons are connected by bonding: the cost of the pier body is much higher than that of the traditional cast-in-place concrete piers, the construction process is complicated, and the construction time is long; ③Grout Metal bellows connection: At present, a few bridges abroad have used this connection structure...
