Abstract

The invention discloses a pipeline through-double-layer-wall sound insulation structure and a construction method, and belongs to the technical field of through-wall pipeline construction. The structure achieves sound insulation and sound reduction of the pipeline through-wall. The pipeline through-double-layer-wall sound insulation structure comprises a first casing pipe and a second casing pipe component which arranged outside the pipeline in a sleeving mode, the second casing pipe component comprises an independent first casing pipe body and an independent second casing pipe body, the first casing pipe body is fixed to the fixed wall, the second casing pipe body is fixed to a floating wall, and the second casing pipe body and the floating wall synchronously move. A first sound absorption material layer is arranged between the outer wall of the pipeline and the inner wall of the first casing pipe, and a metal hose joint is arranged at the end, close to the floating wall, of the pipeline. In the construction process, the fixed wall and the floating wall are firstly constructed, the first casing pipe body and the second casing pipe body are buried, the first casing pipe and the pipeline horizontally penetrates through the first casing pipe body and the second casing pipe body in sequence, and the metal hose joint is located at the end close to the floating wall. Finally, the first sound absorption material layer is arranged. The structure can prevent the pipeline in the floating wall from deforming, and the sound insulation and sound reduction effects of pipeline through-wall can be met. The construction method is easy and convenient to operate and shortens the construction period.

Description

technical field [0001] The invention belongs to the technical field of pipeline construction through walls, and in particular relates to a sound insulation structure and a construction method for pipelines passing through double-layer walls. Background technique [0002] Usually, some ventilation pipes and water pipes will be set in the building walls. When the pipeline is working, the sound of wind or water will form noise, which will affect the sound insulation effect of the building. Therefore, the pipe-through-wall structure of the building wall with high sound insulation requirements should be treated with sound insulation to prevent solid sound transmission between the pipe and the wall. The traditional approach is to fill the gap between the pipe and the wall with sound insulation material to reduce noise pollution. However, when the building wall is a floating wall, because the floating wall has the characteristics of vertical movement, the traditional pipe wall pe...
