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

Embodiment 1

[0026] A construction method for backfilling anti-vibration trenches of sound-absorbing and vibration-isolated concrete materials, comprising the following steps:

[0027] (1) Clean up the construction waste in the anti-vibration ditch and clean up the accumulated water. After cleaning, pour a 0.1m thick C15 concrete cushion at the bottom of the anti-vibration ditch, and then paste 3.9m high and 0.05m thick on both sides of the anti-vibration ditch Polystyrene-like board as a waterproof protective layer;

[0028] (2) In the anti-vibration ditch, lime-sand bricks are used to build the first layer of partition walls at equal intervals. The distance between two adjacent partition walls in each layer of partition walls is 30m, and each partition wall is 0.24m thick and 1m high , with a width of 0.6m, the sound-absorbing and vibration-isolation concrete material is poured between the partition walls of the first floor by pumping to the same height as the partition walls of the firs...

Embodiment 2

[0033] A construction method for backfilling anti-vibration trenches of sound-absorbing and vibration-isolated concrete materials, comprising the following steps:

[0034] (1) Clean up the construction waste in the anti-vibration ditch and clean up the accumulated water. After cleaning, pour a 0.1m thick C15 concrete cushion at the bottom of the anti-vibration ditch, and then paste 3.9m high and 0.05m thick on both sides of the anti-vibration ditch Polystyrene-like board as a waterproof protective layer;

[0035] (2) In the anti-vibration ditch, ordinary fly ash bricks are used to build the first layer of partition walls at equal intervals. The distance between two adjacent partition walls in each layer of partition walls is 35m, and the thickness of each partition wall is 0.24m. The height is 1.2m, the width is 0.8m, and the sound-absorbing and vibration-isolation concrete material is poured between the first-layer partition walls by pumping to the same height as the first-la...

Embodiment 3

[0040] A construction method for backfilling anti-vibration trenches of sound-absorbing and vibration-isolated concrete materials, comprising the following steps:

[0041] (1) Clean up the construction waste in the anti-vibration ditch and clean up the accumulated water. After cleaning, pour a 0.1m thick C15 concrete cushion at the bottom of the anti-vibration ditch, and then paste 3.9m high and 0.05m thick on both sides of the anti-vibration ditch Polystyrene-like board as a waterproof protective layer;

[0042] (2) In the anti-vibration ditch, lime-sand bricks are used to build the first layer of partition walls at equal intervals. The distance between two adjacent partition walls in each layer of partition walls is 40m, and each partition wall is 0.24m thick and 1.5m high. m, 1.2m wide, the sound-absorbing and vibration-isolation concrete material shall be poured between the partition walls of the first floor by pumping to the same height as the partition walls of the first...

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...
