Description

Temporary protective fence for urban road Technical Field The utility model belongs to the field of protective barriers, and particularly relates to a temporary protective barrier for urban roads. Background The guard rail is an important safety facility in the urban traffic system, has both functionality and aesthetic property, and is mainly used for separating traffic flow, guaranteeing driving safety and optimizing urban environment. The guard rail is used for clearly dividing the motor vehicle lanes, the non-motor vehicle lanes and the sidewalk through physical isolation, so that the risks of random lane changing, turning around or crossing of pedestrians by the vehicle are reduced, and the guard rail has certain buffering performance. The existing guard rail is usually of a fixed structure and is fixedly installed on a road surface through expansion bolts, however, along with urban development and construction, road surface construction diversion conditions usually exist in the city, the fixed guard rail is relatively complicated to install and detach, inconvenient to use and poor in flexibility, so that road construction efficiency can be possibly influenced, and road traffic is further influenced. Disclosure of utility model The embodiment of the utility model aims to provide a temporary guard rail for an urban road, which aims to solve the problems in the background art.
