Problems solved by technology

[0002] With the continuous increase of vehicles, nowadays, with the rapid development of the economy, the number of municipal roads is also increasing to meet more pedestrians and vehicles. Municipal roads are divided into ground roads and elevated roads. Municipal roads are generally The central isolation guardrail will be installed to guide and separate the vehicles. In some special cases, such as road rescue, traffic accidents, etc., especially on elevated roads, since ordinary vehicles on elevated roads are not allowed to turn around, if encountered In an emergency, the central barrier needs to be dismantled, so as to allow special vehicles such as rescue vehicles to turn around and arrive at the accident site in the shortest time. When the central guardrail needs to be disassembled, tools such as wrenches are needed to remove the bolts and other fasteners. The removal and installation efficiency is low, which will delay the best rescue time. After the central guardrail is removed, if the oncoming vehicle brakes If it is not timely, it will affect the U-turn of the rescue vehicle, and in serious cases, there will be a traffic accident with the rescue vehicle
