Urban road and construction method thereof

Abstract

The invention discloses an urban road and a construction method thereof, and relates to the technical field of road engineering.The urban road comprises a road body, reinforcing guardrails are arranged on the two sides of the road body, each reinforcing guardrail comprises a plurality of stand columns, upper handrails and lower handrails are arranged on the stand columns, and a plurality of anti-collision assemblies are arranged between the upper handrails and the lower handrails; the anti-collision assembly comprises a fixing base arranged on the lower handrail, a supporting rod is hinged to the fixing base, an anti-collision rotating cylinder is detachably connected to the supporting rod, a threaded rod is connected to the end, away from the fixing base, of the supporting rod, a pressing piece is in threaded connection with the threaded rod, and an embedding sleeve used for embedding the threaded rod is arranged on the upper handrail. And a cover shell is detachably mounted at the opening of the nest. The anti-collision rotary drum has the beneficial effects that the anti-collision rotary drum of the urban road is extremely convenient and easy to disassemble and assemble, the protection effect of a reinforced guardrail can be guaranteed all the time, so that the driving safety of the road is guaranteed, and the construction method of the urban road is high in safety and high in construction efficiency.

Description

technical field [0001] The invention relates to the technical field of road engineering, in particular to an urban highway and a construction method thereof. Background technique [0002] Highways refer to public roads within cities, between urban and rural areas, and in rural areas that are constructed in accordance with the technical standards for highway engineering stipulated by the state, and which have been checked and approved by the highway authorities. Highways refer to those built in accordance with national technical standards that connect cities, between urban and rural areas, between villages and villages, and between industrial and mining bases, including expressways, first-class roads, second-class roads, third-class roads, and fourth-class roads. It does not include trails formed naturally in fields or rural areas. [0003] At present, when existing highways are constructed, guardrails are usually installed on both sides of the road. The guardrails use the d...

Problems solved by technology

[0004] And because the vehicle will contact and rub against the guardrail at the same time when it collides with the guardrail, in order to avoid scratching the vehicle, the existing roads also use rotating barrel guardrails, which can greatly absorb the energy by converting the impact force into rotational kinetic energy. The impact force is strong and the impact is reduced, and when friction occurs with the vehicle, it can also rotate to relieve force and reduce scratches, thereby effectively reducing the consequences of traffic accidents. However, after a traffic accident, the rotating barrel on the rotating barrel guardrail usually It will be deformed and damaged, and because the rotating barrel is fixedly installed on the guardrail, it is difficult to disassemble, and if it is not disassembled and replaced in time, it will affect the protective effect of the guardrail, resulting in a decrease in driving safety on the road
