Abstract

The invention discloses a multifunctional protection device for road and bridge construction, which comprises a bottom frame, a pulley and a lifting and fixing device. tube, the upper end of the shock absorbing device is provided with a fixed frame, the upper end of the fixed frame is provided with a chute one, two sliders one are arranged inside the chute one, and the upper ends of the slider one are provided with support rods, And the middle of the two support rods is fixed by a rotating fixing mechanism, a telescopic spring is arranged between the two support rods, and a support frame is arranged at the upper end of the support rods. This protection device is used for the protection work of road and bridge construction. It has a protective effect on roads and bridges, and has a reminder function for passing vehicles and pedestrians. And the reminder sign has a reminder function to passing vehicles and pedestrians, so as to prevent traffic accidents of vehicles and pedestrians.

Description

Technical field [0001] The invention relates to a protective device, in particular to a multifunctional protective device for road and bridge construction. Background technique [0002] Roads and bridges generally consist of roadbeds, pavements, bridges, tunnel engineering and traffic engineering facilities. Bridge engineering includes the work process of survey, design, construction, maintenance and verification, as well as the science and engineering technology of studying this process. Bridges need a lot of construction, and manpower, material resources, and financial resources are limited; therefore, the technical level is constantly improved, new materials, new techniques, and new bridge styles are used to conduct more accurate numerical analysis of structural behavior and use more accurate structural tests for verification. In order to continuously improve the economic benefits of bridge construction, it has become a requirement of the times. [0003] However, the protectiv...
