Friction and gravity energy dissipation type bridge anti-seismic check block and construction method thereof

Abstract

The invention relates to the technical field of bridge earthquake prevention, in particular to a friction and gravity energy dissipation type bridge anti-seismic check block and a construction methodthereof. The friction and gravity energy dissipation type bridge anti-seismic check block comprises a steel bottom plate, a steel cover, a groove steel block, a small steel checkblock, a steel check block, a steel ball, a transverse spring, a vertical spring, a thick and heavy pulley, a steel corbel web plate, a steel corbel bottom plate, a steel corbel top plate, a steel corbel side plate, a steel corbel bolt, a steel baffle web plate, a steel baffle top plate, a steel baffle side plate and a steel baffle bolt. In the case of earthquake occurrence, earthquake energy is converted into pulley gravitational potential energy to achieve the effect of reducing the earthquake energy on a bridge; internal components generate friction force and consume earthquake energy during movement; meanwhile,earthquake energy can be buffered through the arrangement of the steel springs, so that the problem that the bridge body moves can be relieved, even the possibility of collision between the bridge bodies is reduced, the bridge can be well protected, and harm to the bridge when an earthquake occurs is reduced.

Description

technical field [0001] The invention relates to the field of bridge anti-seismic technology, in particular to a friction and gravity energy-consuming bridge anti-seismic block and a construction method thereof. Background technique [0002] With the continuous acceleration of the urban modernization process, the large concentration of urban population, and the increasing importance of the transportation network in the lifeline of the entire city, the people's dependence on bridges is also increasing. [0003] However, due to the continuous occurrence of earthquakes and the occurrence of disasters, many bridge projects around the world have been damaged in earthquakes in recent decades, which seriously blocked the traffic lifeline in the earthquake area and further aggravated the secondary disasters caused by earthquakes. and post-disaster reconstruction efforts have brought great difficulties. At the same time, as an important social infrastructure, bridges require large in...

Problems solved by technology

[0003] However, due to the continuous occurrence of earthquakes and the occurrence of disasters, many bridge projects around the world have been damaged in earthquakes in recent decades, which seriously blocked the traffic lifeline in the earthquake area and further aggravated the secondary disasters caused by earthquakes. and post-disaster reconstruction efforts have brought great difficulties

At the same time, as an important social infrastructure, bridges require large investment, strong publicity, and difficult maintenance and management. Once the bridge is damaged, it will cause heavy economic losses.
