Description

technical field [0001] The invention relates to the technical field of expressway construction auxiliary equipment, in particular to a temporary protection device for expressway construction. Background technique [0002] With the continuous development of the social economy, the construction of expressways gradually adapts to the development of industrialization and urbanization. The construction of expressways mostly starts from urban ring roads, radiation roads and busy traffic sections, and gradually becomes urban traffic with expressways as the backbone. With the continuous improvement of people's living standards and the continuous increase of the proportion of cars as a means of travel, the increase in the number of cars will inevitably cause a burden on the expressway, and the road surface of the expressway is prone to damage as time goes by. [0003] In order to avoid traffic inconvenience caused by road damage, it is necessary to regularly maintain and repair the u...

Problems solved by technology

[0004] However, the existing temporary protective devices have poor flexibility. Most of the temporary protective devices need to be arranged in order when they are arranged, and the connection between the protective devices is poor. On the road, a large number of protective devices need to be used for splicing, and the handling of the protective devices is time-consuming and laborious, so it does not meet the existing needs. For this, we propose a temporary protective device for expressway construction
