Problems solved by technology

[0003] At present, the road congestion problem is solved by building bridges with steel-concrete structures. Bridges with steel-concrete structures are expensive and have a long construction period. In case of urban reconstruction, only one bridge will be lost in vain.
There is no good way to solve the problem of road congestion at home and abroad

Abstract

The invention discloses a mountable and demountable road bridge which comprises a bridge body. Demountable guardrails are arranged on two sides of the top surface of the bridge body. The bridge body consists of building blocks which are in fastener connection. The mountable and demountable road bridge has the advantages that the road bridge is convenient to mount and demount, can be secondarily used without damage during urban reconstruction, bridge reconstruction cost can be greatly reduced, and meanwhile, labor and material resources are saved. Besides, the mountable and demountable road bridge can be built over narrow rivers and is firm, durable, safe and reliable, and cost can be reduced greatly as compared with reinforced concrete structured bridge same in size.

Description

Technical field: [0001] The invention relates to a road bridge, in particular to a road bridge that can be assembled and disassembled conveniently, can greatly alleviate traffic congestion, save resources, and is safe and reliable. Background technique: [0002] With the rapid development of China's economy, the development of the automobile industry, the growth of per capita GDP, the prosperity of the country and the prosperity of the people, and the increase in the number of various cars and motor vehicles, the road traffic congestion is becoming more and more serious. [0003] At present, the road congestion problem is solved by building bridges with steel-concrete structures. Bridges with steel-concrete structures are expensive and have a long construction period. In case of urban reconstruction, only one bridge will be lost in vain. There is no good way to solve the road congestion problem both at home and abroad. Invention content: [0004] The object of the present...
