Sound-absorption and vibration-isolation concrete material vibration resisting ditch backfill construction method and application

Abstract

The invention provides a sound-absorption and vibration-isolation concrete material vibration resisting ditch backfill construction method. A vibration resisting ditch is cleaned, and a waterproof protecting layer is paved; first layers of separation walls are built in the vibration resisting ditch at equal intervals, and concrete materials are cast between the first layers of separation walls tobe as high as the first layers of separation walls; second layers of separation walls with the same heights, widths and thicknesses with the first layers of separation walls are built on the first layers of separation walls, and the concrete materials are cast between the separation walls to be as high as the second layers of separation walls; the separation walls are continuously built until thevibration resisting ditch is fully filled; and the curing, the top surface polishing and the mold disassembly are performed. The sound-absorption and vibration-isolation concrete material vibration resisting ditch backfill construction method is low in cost, convenient to construct, environment-friendly and safe.

Description

technical field [0001] The invention belongs to the technical field of buildings, and relates to a backfilling construction method and application of a sound-absorbing and vibration-isolating concrete material anti-vibration ditch. Background technique [0002] Noise pollution refers to the noise generated by humans in activities such as industrial production, construction, transportation, and social life that interferes with the living environment of surrounding animals. At present, the main source of environmental noise in the world is traffic noise, including noise generated by cars, ships, planes and trains. Industrial noise is also a major pollution. In addition, construction machinery, entertainment sound reinforcement facilities, and even some office equipment, people Loud noise is a source of noise pollution. For example, the vibration and noise caused by the operation of subway trains is a problem worthy of attention that exists in subways all over the world. Inter...

Problems solved by technology

When excavating, the ditch wall should be sloped or supported by sheet piles, so as to avoid landslide blockage and make the vibration transmission medium continuous without vibration isolation effect. The extruded polystyrene board is set in the middle of the bricks, and the brick wall is built until the anti-vibration ditch is filled, and the upper part is covered with a concrete surface. However, the operation of lime-sand brick masonry is inconvenient, and the workers will face a narrow space when using the lime-sand brick backfill method. Risk of falling objects such as steel bars, aluminum membrane panels, shelves, etc. due to lack of oxygen during operation and surrounding buildings under construction
