Embodiment Construction

[0022] The following is further described in detail by specific embodiments:

[0023] An energy-consuming guardrail for a bridge is arranged on the side of the bridge, and mainly includes a pier 1, a bridge deck 2 and a bridge guardrail 3. In this embodiment, the bridge guardrail is composed of several horizontal steel pipes and several vertical steel pipes, and the vertical steel pipes are composed of several vertical steel pipes. One end is fixedly connected with the bridge deck 2, and the other end is fixedly connected with the horizontal steel pipe. Several horizontal steel pipes are located at the same height and are connected end to end. Several horizontal steel pipes are provided with steel ropes 4. Both ends of the bridge deck 2 are fixedly connected with the bottom surface. The fixed pile, the two ends of the steel rope 4 are respectively fixed on the fixed piles at the two ends of the bridge deck 2, and the benefit is that the impact force of the automobile can easily...

Abstract

The invention relates to the field of bridge guardrails, in particular to an energy-consuming guardrail for bridges. Including bridge piers, bridge decks and bridge guardrails, the bridge guardrails are arranged on both sides of the bridge deck, and the outside of the bridge guardrails are provided with energy-consuming units at equal intervals, and the energy-consuming units are composed of mounting brackets, fixed blocks, sliders, It consists of several groups of piston cylinders, several groups of piston rods, several groups of shock-absorbing springs, several groups of exhaust pipes, several groups of connecting blocks and several groups of connecting ropes. The mounting frame is fixedly connected to the bridge deck, and the fixed blocks are vertically fixed. On the mounting frame, the piston end of a single group of the piston rod is located in the single group of the piston cylinder, and the other end of the single group of the piston rod is fixedly connected with the slider, the slider is located outside the bridge railing, the The shock-absorbing spring is sleeved on the piston rod, and the shock-absorbing spring is located between the piston cylinder and the slider. The technical solution is used to solve the problem that the bridge guardrail in the prior art has poor impact on the vehicle and cannot well prevent the vehicle from rushing out of the bridge guardrail.

Description

technical field [0001] The invention relates to the field of bridge guardrails, in particular to an energy-consuming guardrail for bridges. Background technique [0002] Most bridges are ubiquitous at high altitudes and are used to connect two high grounds, eliminating the time for people to detour. With the widespread popularity of bridges, bridge safety technologies have also been developed one after another. Gradually improving, the safety protection technology of municipal bridges is also gradually improving, and the anti-collision guardrail is also an important part of the bridge safety facilities. When an accident occurs, the existence of the anti-collision guardrail makes the impact of the traffic accident gradually reduced. [0003] However, it often plays a small role in safety protection when a traffic accident occurs. When a collision occurs, either the hardness of the guardrail is too large to cause the vehicle to be destructive, or the hardness is too small, an...
