Abstract

The invention discloses a combined anti-seismic pier column and a template-free construction method thereof. The combined anti-seismic pier column comprises a pier column base for providing supportingforce for a composite pier column; and the composite pier column which is fixed to the upper portion of the pier column base and comprises an outer wrapping sleeve and a pier body, wherein the pier body is sleeved in the outer wrapping sleeve, the outer wrapping sleeve is made of ultrahigh-toughness concrete, and the pier body is formed by pouring micro-expansion concrete. The composite pier column structure has good anti-cracking capacity and anti-seismic energy absorption capacity.

Description

technical field

[0001] The invention belongs to the technical field of bridge engineering, and in particular relates to a combined anti-seismic pier column and a template-free construction method thereof. Background technique

[0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0003] At present, bridge piers are mainly constructed of ordinary concrete and steel bars. Under seismic loads, the potential plastic hinge zones of bridge pier columns are located at the bottom and top of the pier body. Engineering practice shows that simply increasing the strength of concrete or adding reinforcement to improve the aseismic performance of bridge piers has a limited effect. This is because, on the one hand, the...
