Prefabricated assembly pier system with separated load bearing and anti-seismic mechanisms

Abstract

The invention discloses a prefabricated assembly pier system with separated load bearing and anti-seismic mechanisms and belongs to the field of bridge engineering. The prefabricated assembly pier system with the separated load bearing and anti-seismic mechanisms comprises a bearing platform, a pier bottom segment, pier upper segments and a capping beam; the pier bottom segment comprises a horizontal anti-seismic member and a vertical bearing member; fiber mortar beds are arranged between the pier upper segments and the pier bottom segment, between the pier upper segments and between the pierupper segments and the capping beam; steel bar shear keys are arranged between the pier upper segments and the pier bottom segment, between the pier upper segments and between the pier upper segmentsand the capping beam to connect the pier upper segments with the pier bottom segment, connect the pier upper segments and connect the pier upper segments with the capping beam; the pier bottom segmentand the bearing platform are poured together; the pier bottom segment and the pier upper segments are connected with each other through sleeves to form a whole body; and the pier upper segments and the capping beam are connected with each other through corrugated pipes to form a whole body. According to the prefabricated assembly pier system with the separated load bearing and anti-seismic mechanisms, the repairing speed of the pier after earthquakes is increased, and the disturbance to the surrounding environment is reduced; and the prefabricated assembly pier system with the separated loadbearing and anti-seismic mechanisms has important instruction significance for promoting the application of a prefabricated assembly technology in high intensity areas.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to a prefabricated assembled bridge pier system with separated load-bearing and anti-seismic mechanisms. Background technique [0002] Traditional bridge construction generally adopts the construction technology of cast-in-place concrete. This construction technology not only has the disadvantages of long construction period, large environmental disturbance, and high energy consumption in the industry, but also is not suitable for bridges in offshore areas, severe cold areas, and areas with strict environmental protection. building. In order to alleviate the above problems, prefabricated bridge technology began to be applied and developed in bridge construction. [0003] The essence of prefabricated and assembled bridge technology is to complete the construction process such as on-site formwork, binding steel bars and pouring concrete in the prefabrication plant, and divide the pr...
