Description
Technical field
The invention belongs to municipal works apparatus fields, and in particular to arrive a kind of isolation guardrail, more particularly a kind of municipal administration
Engineering combined isolation guardrail.
Background technique
The town road guardrail, which is called, does the galvanized plastic-sprayed steel guard rail of urban transportation, and municipal guardrail sheet makes as plastic-steel structure
It has the characteristics that cost of manufacture is lower, and municipal guardrail is mostly used to play the role of separation to pedestrian and motor vehicle in road both sides,
It is applicable in urban transportation thoroughfare, highway centre greenbelt, bridge, Class II highway, township road and each highway tollgate
Deng isolation, existing political affairs road guard function is relatively simple, is correspondingly improved although having, but still it is impossible to meet people
Demand when using；
There are certain drawbacks in existing political affairs road guard, traditional political affairs road guard, which does not have, to be folded during use
Container structure can occupy biggish space during political affairs road guard is transported and carried, and increase the transfer of political affairs road guard
Difficulty, traditional political affairs road guard do not have composite assembly structure, and the safety between multiple political affairs road guards is more time-consuming, traditional political affairs
Road guard does not have lifting adjusting structure, and no decree political affairs road guard is mutually converted between movement and fixation, and structure is simple,
Function is relatively simple, and certain adverse effect is brought to user.
Summary of the invention
In order to overcome above-mentioned technical problem, it is isolated the purpose of the present invention is to provide a kind of municipal works with combined type and is protected
