Embodiment Construction

[0036] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0037] In the embodiment of the present invention, such as Figure 1-9 As shown, a prefabricated segmental pier is provided, and the prefabricated segmental pier includes a pier body 500 and a jacket 400 . Among them, the pier body 500 is a hollow or solid cement column, the overall shape is round or square, etc., and its specifications can be adjusted appropriately according to the construction requirements; in order to increase the supporting strength of the pier body, several longitudinal reinforcement ribs are arranged inside the pier body 500 600, the length of the longitudinal rib 600 is the same as the length of the pier body 500.

[0038] A steel liner 300 is installed at one end of the pier body 500. The steel liner 300 is barrel-shaped as a whole, and its cross-sectional shape is the same as that of the pier body 500. The wall t...

Abstract

The invention discloses a prefabricated section bridge pier and its application in bridge construction. The prefabricated section bridge pier includes a bridge pier body and a sheath; The parts include a connecting steel plate fixed at the end of the pier body and a PBL connecting cylinder passing through the connecting steel plate. The PBL connecting cylinder is provided with a shear connection hole, and the PBL connecting cylinder is inserted into the shear connection hole at one end of the pier body. A perforated rib, the shear connection hole extending out of the outer end of the pier body is equipped with a second perforated rib; the side wall of the steel liner is provided with a vertical wall hole, and the side wall of the pier body is provided with a mounting hole; the sheath includes two pieces The sheath plate is provided with fixing holes opposite to the vertical wall holes. The segmental bridge pier in the present invention can be quickly assembled with low construction risk, and has small initial defects, guaranteed bearing safety, high resource utilization rate, less environmental pollution, and economical durability.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, and in particular relates to a prefabricated segmental bridge pier and its application in bridge construction. Background technique [0002] With the development of the economy and the progress of the society, the requirements for the construction speed of the highway and railway transportation network are getting higher and higher, and the requirements for environmental protection are getting stricter. At the same time, the safety, economy, construction risk controllability, and durability Sex and other aspects are also more and more important. This is especially true for bridge piers, which are the key link of a large number of bridges in the road network. [0003] The usual bridge piers are bound with steel bars, covered with supports and formwork at the construction site, then poured concrete, and removed the formwork after reaching the strength requirements. Due to the process a...
