Example Embodiment

[0038] The present invention will be further explained below in conjunction with the embodiments and the drawings of the specification.

[0039] The prefabricated pier column can be a hollow pier or a solid pier. The cross-section form can be round, rectangular or square. It can be a fixed or variable cross-section. Now take the circular cross-section solid flower pot type pier as an example. :

[0040] A prefabricated bridge pier, such as figure 1 , figure 2 As shown, it includes pier cap section 1, pier body section 2 and cap 3; among them, the length of the built-in steel protective tube 4-1 on the bottom of the pier cap section 1 is 30cm, and the built-in steel 8 upper anchor holes 9-1 are evenly distributed on the barrel wall of the protective tube 4-1; the top of the bearing platform 3 extends out of the circular lower built-in steel protective tube 4-2 with a length of 30cm, and the lower built-in steel protective tube 4-2 8 lower anchor holes 9-2 are evenly distributed on...

Abstract

The invention discloses a prefabricated fabricated bridge pier and an assembling construction method thereof. The prefabricated fabricated bridge pier comprises a pier cap segment, a pier body linearsegment and a bearing platform. Grooves which are each formed by two concentric round steel casings are formed in the head and the tail of the pier body linear segment correspondingly; the pier cap segment is a bridge pier straight-curved transition segment, the pier cap is internally provided with the round steel casings, and the round steel casings extend out of the lower end of the pier cap tobe matched with the grooves of the linear segment; a round steel casing is arranged in the center of the top of the bearing platform and extends out of the top surface of the bearing platform to be matched with the grooves of the linear segment; and the steel casings are connected through bolts. According to the prefabricated fabricated bridge pier and the assembling construction method thereof, the flowerpot-shaped bridge pier is subjected to prefabricated assembling, the bridge pier is divided into the pier cap segment and the pier body segment, the assembling direction of the bridge pier isunified, the difficulty of site construction alignment is reduced, the construction time is shortened, pollution of site construction to surrounding environment is reduced, and the influence of construction on surrounding traffic is minimized.

Description

technical field [0001] The invention relates to a prefabricated assembled bridge pier and an assembly construction method thereof, belonging to the field of bridges. Background technique [0002] With the rapid development of construction industrialization, the bridge structure will inevitably enter the industrialization period of rapid assembly. Segmentally assembled precast concrete piers have the advantages of fast construction, reliable quality, little impact on the environment, and little impact on traffic. This type of bridge pier is a structural system that divides the pier body into several segments vertically, the longitudinally stressed steel bars are disconnected between the segments, and these prefabricated components are assembled through certain connection methods. [0003] There are many ways to connect prefabricated piers, and the technical purpose of the present invention is to provide a safe and reliable assembly connection method and construction method. ...
