Abstract

The invention discloses a connecting structure and method for precast assembled pier segments, and belongs to the field of bridge engineering. The connecting structure is a precast assembled steel tube concrete pier based on connection of ultra-high performance concrete (UHPC), an inner sleeve connecting steel pipe and a high-strength bolt. The connecting structure comprises a bearing platform, apre-buried segment, a precast steel tube concrete segment, the inner sleeve connecting steel pipe and a cover beam. The exteriors of the precast steel tube concrete segment and a pre-buried segment are precast steel pipe segments. The precast steel tube concrete segment is partially filled with concrete, and reserved heights of the two ends of the precast steel tube concrete segment are half thatof the inner sleeve connecting steel pipe. The UHPC is applied to the precast pier segments during connection, excellent compressive and tensile properties of the UHPC are fully utilized, and the problem of weak connection of the precast pier segments is solved.

Description

technical field

[0001] The invention belongs to the field of bridge engineering, and in particular relates to a structure and method for segmental connection of prefabricated assembled bridge piers. Background technique

[0002] Concrete-filled steel pipe piers are widely used in urban bridges, high-pier bridges in mountainous areas, and sea-crossing bridges because of their high strength and stiffness, as well as excellent ductility and energy dissipation capacity. It is used in bridge construction in high-intensity areas. With the rapid development of urban traffic, mountain bridges and sea-crossing bridges, the demand for rapid bridge construction in limited sites has become increasingly prominent. At the same time, in the current urban bridge construction, owners and residents have put forward higher requirements for bridge construction, that is, in addition to ensuring the safety and durability of the bridge structure, it is also necessary to avoid or reduce traffic in...
