Technical Field

The invention relates to the technical field of foundation treatment, in particular to a noise reduction method in a compaction pile construction process.

Background

The compaction pile is formed by pressing or driving a steel pipe with a pipe plug, a valve or a conical head into an underground compaction soil layer to form a hole, and then throwing fillers such as lime soil, gravel and the like into the hole. The compaction pile composite foundation can effectively eliminate the collapsibility of the large-thickness loess in the collapsibility loess foundation treatment.

In actual construction, when crowded compact pore-forming through the crowded compact stake, can be through pile driver hammering crowded compact stake, with crowded compact stake drive in the soil, but there is very big sound through pile driver hammering crowded compact stake, can form noise pollution, therefore the amortization method in the crowded compact stake construction technology of now urgent need.
