Abstract

The invention relates to an integral abutment-concrete filled steel tube pile joint with laminated rubber. The integral abutment-concrete filled steel tube pile joint comprises a concrete bridge abutment and a concrete-filled steel tube pile, and is characterized in that a laminated rubber device is arranged at the top of the concrete-filled steel tube pile; the laminated rubber device comprises laminated rubber; and the laminated rubber is formed by alternately laminating rubber sheets and stiffening steel plates layer by layer. The invention further provides a construction method of the integral abutment-concrete filled steel tube pile joint. The integral abutment-concrete filled steel tube pile joint can improve the lateral displacement capacity of the abutment-pile joint.

Description

technical field [0001] The invention belongs to the field of integral abutment bridge structure design, and in particular relates to an integral abutment-concrete steel pipe pile node with laminated rubber devices. Background technique [0002] In order to solve the problem of expansion and deformation of bridges under the action of temperature, the traditional method is to set expansion joints. However, under normal working conditions, expansion joints are easily damaged by factors such as rain erosion, foreign matter filling, vehicle load and foundation settlement. The integral abutment bridge that cancels the expansion device and the support at the abutment, the beam end is directly integrated with the abutment pouring, which fundamentally solves the problem of damage to the bridge expansion joints. However, the deformation and force of the bridge superstructure are directly transmitted to the substructure, which puts forward higher requirements on the deformation capacit...
