水下捆绑爆破切割法拆除码头桩基工艺

Technology for Cutting of Piles for a Wharf by Underwater Strap-on Blasting

通过对厦门东渡19号泊位桩基码头几种桩基拆除试验及工期成本分析,重点阐述了水下捆绑爆破法的工艺原理、方案设计及实施效果。结果显示,水下捆绑爆破切割技术用于高桩码头桩基拆除,具有工期短、成本低、工艺简单等特点。探索出了一种水下拆除桩基的新方法。

Based on the trial tests of different pile foundation demolition methods and analysis of construction period and cost during the execution of No.19 Berth in Dongdu Port Area of Xiamen Port, the paper expounds the working mechanism, method design and result of execution of underwater strap-on blasting method for demolition of the pile foundation. The result indicates that the method of underwater strap-on blasting to cut piles for wharfs is characterized by short working duration, low cost and simple technology. A new approach for underwater demolition of pile foundations has been explored.
