Abstract

The invention discloses a bridge shock absorption system and an implementation method. The bridge shock absorption system comprises a bridge body, a first supporting base, a second supporting base, afirst oblique supporting column, a second oblique supporting column, a bearing beam, multiple inhaul cables and a damper. The damper comprises an outer barrel and an inner barrel, the inner barrel extends to the outer portion of the outer barrel, a first end socket is installed on one side in the outer barrel, and a second end socket is installed on the other side in the outer barrel. An oil cavity is formed in the outer barrel, a cavity is formed in the inner barrel, a large-diameter piston is installed in the oil cavity in a sliding mode, a small-diameter piston is installed in the cavity ina sliding mode, oil grooves are formed in the large-diameter piston in the axis direction of the large-diameter piston, both the large-diameter piston and the small-diameter piston are installed on apiston rod, a first connecting seat is installed at one end of the piston rod, a first connecting hole is formed in the first connecting seat, a second connecting seat is installed at the outer end of the inner barrel, and a second connecting hole is formed in the second connecting seat.

Description

technical field [0001] The invention relates to the technical field of bridge damping, in particular to a bridge damping system and an implementation method. Background technique [0002] Bridges are an important part of the "lifeline project". After the earthquake, for the needs of emergency rescue and earthquake relief, its importance is even more obvious. In an earthquake, the collapse of a large or medium-sized bridge will cause a complete interruption of traffic, especially in environments such as the Yangtze River and Yellow River wetlands. It is often more difficult to repair projects. It is self-evident that this will bring difficulties to emergency rescue work, and even increase The extent of earthquake damage. In order to reduce the damage of bridge structures caused by earthquakes, scholars from various countries have conducted extensive and in-depth research on the shock absorption of bridge structures. At present, the methods of shock absorption that are relat...
