Example Embodiment

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

[0036] Such as figure 1 As shown, a segmental self-resetting bridge pier with transverse shear resistance of the present invention includes a transverse shear pier bottom section 1, a plurality of transverse shear pier body sections 2 and a transverse shear pier installed on a base 8. The top section 3, the bottom section of the transverse shear pier 1, the plurality of transverse shear pier body sections 2, and the top section 3 of the transverse shear pier are all interlocked with each other through the occlusal joint 4, using prefabricated assembly The method forms the whole pier column. Shear pins 5 are continuously arranged between the segments, and cooperate with the occlusal joint 4 to realize effective transmission of shear force. It also includes multiple self-resetting components 6 penetrating through and anchored to the lateral shear pier...

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...
