Multifunctional protective device for road and bridge engineering

Abstract

The invention provides a multifunctional protective device for road and bridge engineering, including pouring piles, reinforced concrete support columns, main protective frame structure, locking connecting frame structure, peripheral connecting wire rope, damping connecting frame structure, bottom wire mesh, bridge main body, road The edge, guardrail fixed column, V-shaped connecting plate, bottom protective plate, middle arc plate and top protective plate, the reinforced concrete support column is poured on the upper part of the pouring pile; the main protective frame structure is installed on the reinforced concrete support outside of the column. The arrangement of the U-shaped connecting seat, the overturned locking card plate, the trapezoidal locking block and the threaded rod of the present invention is beneficial to locking the connection between the overturned locking card plate and the trapezoidal locking block, and prevents the appearance of the overturned locking card plate. Flip over, causing the trapezoidal locking block to slide out from the inside of the flip locking clip.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and particularly relates to a multifunctional protective device for road and bridge engineering. Background technique [0002] Road bridges are generally composed of subgrades, pavements, bridges, tunnel engineering and traffic engineering facilities. Slab bridge is a common bridge type with large volume and wide area among highway bridges. It has a simple structure and clear force, and can use reinforced concrete and prestressed concrete structures. [0003] However, the existing protective devices for road and bridge engineering still have the problems that the connection of the top protective net cannot be locked, the protective effect on the column is poor, and the impact force of the metal net on foreign objects cannot be buffered. [0004] Therefore, it is very necessary to invent multifunctional protective devices for road and bridge engineering. SUMMARY OF THE INVENTION ...
