Embodiment

[0022] like Figure 1-Figure 5 As shown, a fragmented prefabricated concrete pier includes a pier body 1, characterized in that: the pier body 1 includes at least one pier segment 2, and the pier segment 2 is composed of a hollow shell 3 and a post-filled first concrete 4;

[0023] The hollow shell 3 includes a plurality of pier piers 5, and pier connection joints are arranged between the pier piers 5;

[0024] Pier connection joints 12 are arranged between the pier segments 2 and between the pier segments 2 and caps and cap beams.

[0025] Specifically, the pier connection joint is the pier connection wet joint 6 and / or the pier connection dry joint 7 .

[0026] Specifically, the pier connection wet joint 6 includes U-shaped bars 8 , vertical longitudinal bars 9 and second concrete 10 .

[0027] Specifically, the pier connection dry joint 7 is provided with a shear force bond and epoxy glue is applied, and a prestressed tendon 11 is provided on the hollow shell 3 in order t...

Abstract

The invention discloses a split precast concrete bridge pier. The bridge pier comprises a bridge pier body, wherein the bridge pier body at least comprises a bridge pier section, and the bridge pier section is composed of a hollow shell; the hollow shell comprises a plurality of pier sheets, and pier sheet connecting joints are arranged between the pier sheets; and bridge pier connecting joints are arranged between the bridge pier sections and between the bridge pier sections and the bearing platform as well as between the bridge pier sections and the cover beam. The bridge pier is advantaged in that prefabricating and assembling of large-size bridge piers and bridge pier bodies with limited transportation conditions can be achieved.

Description

technical field [0001] The invention relates to the field of bridge pier structures, in particular to a sliced ​​prefabricated concrete bridge pier. Background technique [0002] Prefabricated assembled bridge piers have many advantages and have been widely recognized by the society. [0003] Conventional prefabricated bridge piers have the characteristics of large size and heavy weight, which put forward higher requirements for transportation and hoisting during construction, and usually require special vehicles and equipment to carry out construction operations. [0004] For some bridge piers that are difficult to transport in cities and mountainous areas, it is difficult to carry out prefabricated assembly process construction with existing methods. [0005] For some particularly large-sized piers, there is no suitable way to transport the prefabricated components of the piers. [0006] How to make the prefabricated bridge components smaller and lighter has become a tec...
