Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] Such as figure 1As shown, a transverse shear-resistant segmental self-resetting bridge pier of the present invention includes a transverse shear-resistant pier bottom segment 1 installed on a base 8, a plurality of transverse shear-resistant pier body segments 2 and a transverse shear-resistant pier The top segment 3, the bottom segment 1 of the transverse shear pier, the multiple transverse shear pier body segments 2 and the top segment 3 of the transverse shear pier are all fitted together through the occlusal joint 4, and the prefabricated and assembled The method forms the pier as a whole. The shear pins 5 are arranged continuously between the segments, and cooperate with the occlusal joint 4 to realize the effective transmission of shear force. It also includes a plurality of self-resetting components 6 penetrating throu...

Abstract

The invention relates to a transverse shear resisting section type self-resetting pier and a construction method thereof. The pier comprises a transverse shear resisting pier bottom section, a plurality of transverse shear resisting pier body sections and a transverse shear resisting pier top section. The transverse shear resisting pier bottom section, the transverse shear resisting pier body sections and the transverse shear resisting pier top section are connected through meshing connecting faces and shear resisting bolts. The pier further comprises a plurality of self-resetting components. The self-resetting components penetrates and are anchored to the transverse shear resisting pier bottom section, the transverse shear resisting pier body sections and the transverse shear resisting pier top section through reserved holes. The invention further provides a mounting method of the pier. The self-resetting pier is simple in structure and convenient in material taking. The mounting method is simple, practical, safe and reliable, and the actual application difficult of section type concrete piers is solved.

Description

technical field [0001] The invention relates to the fields of bridge engineering and structural engineering, in particular to a transverse shear-resistant segmental self-resetting bridge pier and a construction method thereof. Background technique [0002] With the rapid development of my country's economy and society, especially the rapid development of highway and railway traffic, the design of bridge structures is facing higher requirements, among which the mechanical properties and construction convenience of bridge piers are particularly important. [0003] Conventional ductility-based design of concrete piers focuses on ensuring the safety of bridges under extreme load conditions. It has excellent mechanical properties and strong ductile deformation capacity, and has been widely used. However, in actual engineering, the overall design of concrete piers is difficult to avoid the following disadvantages: (a) the amount of concrete poured at one time is large, the pouring...
