A bridge swivel construction structure and its construction method

Abstract

The invention discloses a bridge swivel construction structure and a construction method thereof; it belongs to the technical field of bridge construction; its technical points include a steel-concrete lower base, an installation groove is opened in the top center of the steel-concrete lower base, and the installation groove A ball hinge mechanism is arranged inside; the ball hinge mechanism includes a lower ball hinge assembly and an upper ball hinge assembly, and the upper ball hinge assembly is located directly above the lower ball hinge assembly; the lower ball hinge assembly includes a spherical lower plate, and the spherical surface There is a placement groove in the center of the top of the lower plate, and a plurality of circular grooves are evenly distributed on the outside of the placement groove. Groove; the inside of the circular groove is equipped with a circular lubricating plate, the inside of the hemispherical groove is equipped with a hemispherical lubricating plate, and the circular lubricating plate and the hemispherical lubricating plate are integrally formed; the present invention is effective It saves manpower, reduces construction difficulty, reduces construction workload, and improves bridge construction efficiency.

Description

technical field [0001] The invention relates to bridge construction, and more specifically, relates to a bridge swivel construction structure and a construction method thereof. Background technique [0002] Bridge swivel construction refers to the prefabrication of the half-bridge on both sides of the river or at a suitable position by using the terrain and using a simple support, and then the bridge structure itself is used as the rotating body to rotate the two half-bridges to the bridge position axis. A bridge construction method in which the positions are closed into a bridge. [0003] The bridge swivel construction structure in the prior art still has some shortcomings in the actual application process. For example, in order to ensure the smooth performance of the bridge pile, after the installation of the lower spherical joint is completed, multiple hemispherical recesses on the top of the lower spherical joint are required.

[0003] The bridge swivel construction structure in the prior art still has some shortcomings in the actual application process. For example, in order to ensure the smooth performance of the bridge pile, after the installation of the lower spherical joint is completed, multiple hemispherical recesses on the top of the lower spherical joint are required. Spread butter in the pit, put the hemispherical polytetrafluoroethylene plate with good lubricating properties into the pit, and finally hang the upper ball joint to the top of the lower ball joint. In the above process, when applying butter, generally by The construction personnel carry out manual operations, and the workload is heavy. At the same time, the butter in each pit is not uniform enough, and it is easy to have too much or too little butter in some pits. It is necessary to adjust the position of the hemispherical PTFE plate so that the inner surface of the PTFE plate and the inner surface of the lower ball joint remain smooth. The operation is difficult and the workload is large, which affects the bridge rotation. The overall construction efficiency of the body
