Description

An isolation belt filling paver

technical field

The invention relates to an isolation belt filling paver, in particular to a paver used for highway isolation belt filling operations, and belongs to the technical field of paver.

Background technique

According to the expressway design specification, an isolation belt is designed in the middle of the expressway, and low plants are planted in it to prevent the opposite traffic lights from dazzling and ensure driving safety. In some mountain roads, due to some drawbacks in the structural design of the original intermediate isolation belt, it cannot play a blocking role. When a traffic accident occurs, the accident vehicle may cross the middle isolation belt and rush to the opposite lane, causing greater secondary loss of personnel and goods. Therefore, according to the characteristics of local road traffic practices, some provinces have designed the middle isolation belt as pre-installed cement concrete structural walls on both sides, filled with soil in the middle, and then planted flowers, plants and trees inside to prevent dazzling. By strengthening the isolation belt, the occurrence of secondary accidents can be effectively prevented.
