Collision reduction device modularized assembling box easy to detach and used for surface of bridge pier

The invention discloses a collision reduction device modularized assembling box easy to detach and used for the surface of a bridge pier. The collision reduction device modularized assembling box comprises a front buckle plate, bolts, L-shaped metal piece bases, a rubber ring, a metal cover plate and a rear buckle plate. The front buckle plate and the rear buckle plate are attached to the periphery of the bridge pier and are connected together through the bolts. The L-shaped metal piece bases for fixing a circular-pipe-shaped collision reduction device are arranged on a bottom plate of the front buckle plate. Four L-shaped metal piece bases form a set. The circular-pipe-shaped collision reduction device is inserted into a small circle defined by the four L-shaped metal piece bases. The rubber ring and the metal cover plate form a cylindrical box. The cylindrical box covers the outer face of the circular-pipe-shaped collision reduction device. The collision reduction device modularized assembling box is easy to install and detach, can assist the bridge pier in absorbing the impact energy exerted by a vehicle on the bridge pier, is an installing, detaching, protecting and energy absorption assisting integrated multifunctional assembling box for the bridge pier collision reduction device, and can be applied in a modularized mode.
