Vibration and noise reducing structure for driving in highway tunnel and construction method of vibration and noise reducing structure

Abstract

The invention discloses a vibration and noise reducing structure for driving in a highway tunnel and a construction method of the vibration and noise reducing structure, and can be used for reducing vibration and noise for driving in the highway tunnel in a sensitive region. The vibration and noise reducing structure comprises a tunnel structure, backfill concrete, drainage systems and the like, and a graded crushed stone vibration reducing layer and a substrate surface layer are paved on the backfill concrete layer by layer; an upper layer asphalt water sealing layer is paved at the top of the graded crushed stone vibration reducing layer; lower layer asphalt water sealing layers are paved at the top of the backfill concrete, and the connection joint of the backfill concrete and a gravel water seepage layer; a plurality of branch warehouse diaphragm beams buried in the graded crushed stone vibration reducing layer are arranged between the upper layer asphalt water sealing layer and the top of the gravel water seepage layer; a rubber strip which is embedded and fixed is arranged at the top of each branch warehouse diaphragm beam; the top surface of the substrate surface layer is used for allowing vehicles with loads to drive; the rubber strips are used for bearing the substrate surface layer; and therefore, the vibration and noise reducing structure has the advantages of being simple in configuration, stable in structure, convenient to use, low in manufacturing cost, easy in material obtaining and the like. The vibration and noise reducing structure is combined with a corresponding construction method, the vibration and noise for driving in the highway tunnel can be effectively eliminated, and the economic benefits and the social benefits are obvious.

Description

technical field [0001] The invention relates to the construction field of a road tunnel driving vibration and noise reduction structure, in particular to a road tunnel driving vibration and noise reduction structure and a construction method thereof. Background technique [0002] Urban rail transit and subways mostly pass in residential areas. How to take effective measures to reduce the impact of vibration and noise caused by trains on the environment has become one of the hot issues. There are many ways to solve the vibration and noise reduction of driving, such as using Track damper fasteners, rubber floating slab track bed, steel spring floating slab track bed, elastic short sleeper, high elastic modulus emulsified asphalt cement mortar ballastless track, etc. And road tunnels often encounter vibration and noise sensitive areas when driving through. Because the vibration and noise of road tunnels are relatively smaller than urban rail transit and subway, the above method...

Problems solved by technology

And road tunnels often encounter vibration and noise sensitive areas when driving through. Because the vibration and noise of road tunnels are relatively smaller than urban rail transit and subway, the above methods are not suitable for vibration reduction of road tunnels due to adaptability or cost. Noise reduction, so it is obviously necessary to develop a road tunnel driving vibration and noise reduction structure with stable structure, convenient use, low cost and easy material retrieving and its corresponding construction methods
