Problems solved by technology

[0003] Most of the existing prefabricated segmental assembly piers adopt the same prefabricated segmental assembly technology, but the joints of the two assemblies are mainly subject to shear force, and the bearing capacity is low, and there are often problems of insufficient shear force and stability

Embodiment 1

[0024] Embodiment 1, the prefabricated section-assembled concrete pier of the present invention includes a pier body assembled from several pier prefabricated sections from bottom to top. This embodiment takes two pier prefabricated sections as an example, including the upper pier prefabricated section 1 and the lower pier pier The prefabricated section 2, the pier prefabricated section 1 and the lower pier prefabricated section 2 are all columnar structures, the connection of two adjacent pier prefabricated sections is provided with a shear key 3, and the upper end surface and the lower end surface of the upper pier prefabricated section 1 are provided with useful For installing the top installation groove 101 and the bottom installation groove 102 of the shear key, the upper end surface and the lower end surface of the lower pier prefabricated section 2 are provided with the top installation groove 201 and the bottom installation groove 202 for installing the shear key. The u...

Embodiment 2

[0032] Embodiment 2, the difference between this embodiment and Embodiment 1 is that the groove 8 in this embodiment is continuous and plays the same role, but forms a ring, so that less impurities or dust can enter the accommodating chamber Inside.

Abstract

The invention discloses a prefabricated segment assembling concrete bridge pier and an assembling method. Top mounting grooves for mounting shear keys and bottom mounting grooves for mounting the shear keys are correspondingly formed in the upper end surface and the lower end surface of a bridge pier prefabricated section, the upper end surface of a lower part bridge pier fabricated section is connected with the lower end surface of an upper part bridge pier prefabricated section in an abutting-against mode, thus the notches of the top mounting grooves of the lower part bridge pier prefabricated section are opposite to those of the bottom mounting grooves of the upper part bridge pier prefabricated section, the top mounting grooves and the bottom mounting grooves are matched with each other to form containing cavities for containing the shear keys, grouting holes communicating with the containing cavities and slurry discharging holes communicating with the containing cavities are formed in the surface of the bridge pier prefabricated section, grouting materials are solidified to form the shear keys, and the shear keys are arranged through the method. The bridge pier has large shearcapacity, thus seamless assembling between the bridge pier prefabricated sections is actually achieved, the two bridge pier prefabricated sections are not prone to sliding, water is prevented from entering the inner part of a bridge pier to erode the internal structure of the bridge pier, and thus the shear capacity is further improved.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a prefabricated segmentally assembled concrete pier and an assembling method thereof. Background technique [0002] The bridge pier is a sub-structure that supports the bridge span structure and transmits the constant section and vehicle live load to the foundation, and the bridge abutment is located on the two lakes of the bridge. The piers are between the two abutments. The function of the bridge pier is to support the bridge span structure, and the surface abutment support not only plays the role of supporting the bridge span structure, but also connects with the embankment and prevents the embankment from slipping. [0003] Most of the existing prefabricated segmental assembly piers adopt the same prefabricated segmental assembly technology, but the joints of the two assemblies are mainly subjected to shear force, the bearing capacity is low, and there are often p...
