Multifunctional protection device for road and bridge engineering

Abstract

The invention provides a multifunctional protection device for road bridge engineering. The device comprises a poured pile, a reinforced concrete supporting column, a main body protection frame structure, a locking connecting frame structure, a peripheral connecting steel wire rope, a damping connecting frame structure, a bottom steel wire mesh, a bridge main body, a road edge, a guardrail fixing column, a V-shaped connecting plate, a bottom protection plate, a middle arc-shaped plate and a top protection plate. The reinforced concrete supporting column is poured on the upper portion of the poured pile. The main body protection frame structure is installed on the outer side of the reinforced concrete supporting column. Through the arrangement of a U-shaped connecting base, an overturning locking clamping plate, a trapezoidal locking block and a threaded rod, the connecting position of the overturning locking clamping plate and the trapezoidal locking block can be locked, and the situation that the trapezoidal locking block slides out from the inner side of the overturning locking clamping plate due to overturning of the overturning locking clamping plate is prevented.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a multifunctional protective device for road and bridge engineering. Background technique [0002] Road bridges are generally composed of several parts such as roadbed, road surface, bridge, tunnel engineering and traffic engineering facilities. The slab bridge is a commonly used bridge type with a large quantity and a wide area among highway bridges. It has a simple structure and clear force, and can adopt reinforced concrete and prestressed concrete structures. [0003] However, the existing protective devices for road and bridge engineering still have the problems of being unable to lock the connection of the top protective net, poor protection effect on the column and inability to buffer the impact force of the metal net on foreign objects. [0004] Therefore, it is necessary to invent multifunctional road and bridge engineering protective device. ...
