A shock-absorbing system for super-tough concrete bridges

Abstract

The invention discloses a super-tough concrete bridge shock-proof system which comprises a pile group arranged on a foundation soil layer. The upper portion of the pile group is covered with a gravellayer, a pouring bearing platform is arranged on the upper portion of the gravel layer, the upper portion of the pouring bearing platform is connected with a bridge pier, a capping beam is arranged atthe top of the bridge pier, a fluctuating power generation device is arranged on the pouring bearing platform, sulfur concrete boxes are arranged on the periphery of the pouring bearing platform, sulfur concrete is poured into the sulfur concrete boxes, heating wires are embedded into the sulfur concrete and electrically connected with piezoelectric crystals, and a hydraulic connecting rod mechanism is arranged between the bridge pier and a bridge. Energy generated by an earthquake is transformed into electric energy by the fluctuating power generation device, the hydraulic connecting rod mechanism at the tops of the sulfur concrete and the bridge pier is further used for comprehensively absorbing the energy, the system is reasonable in design, the earthquake energy absorption capacity ofa bridge structure is greatly improved, and impact of the earthquake energy on the bridge pier is reduced.

Description

technical field [0001] The invention belongs to the field of bridge damping, and in particular relates to a super-tough concrete bridge damping system. Background technique [0002] Bridge is a key hub in traffic engineering and an important node to ensure road traffic. Due to the structural characteristics of bridge engineering itself, it is extremely vulnerable to damage under extreme conditions such as earthquakes. In the past two decades, bridge structures have been severely damaged in previous major earthquakes, causing huge economic losses. Among them, although a large number of bridges did not collapse after experiencing the earthquake, due to the special damage location and serious damage degree of some components in the substructure of the bridge, it was difficult to reinforce and repair them after the earthquake, resulting in the whole bridge having to be demolished and rebuilt, resulting in Huge material waste and economic losses have also greatly affected the re...

AI Technical Summary

Problems solved by technology

However, the bridge pier is located on the surface. Once a large-scale earthquake occurs, the lateral slip of the cast cap will be large without any buffer, which will cause the problem of disconnection between the bridge pier and the bridge deck, which will affect the safety of the bridge.
