浅析水下冲孔灌注桩斜面岩层爆破成孔技术

Analysis of a coring by blast Technique for Underwater Construction of Punched Cast-in-situ Pile at Inclined Stratums

针对水下冲孔灌注桩通过斜面岩层成孔困难、易出现斜孔、施工进度慢等情况,本文介绍斜面岩层爆破成孔技术及取得的经济效益,为水下冲孔灌注桩通过斜面岩层施工提供借鉴。

It is difficult to use conventional techniques for underwater construction of punched cast - in - situ piles at inclined stratums, which would cause problems such as tilted holes and low construction efficiency. This paper introduces a coring by blast technique which has the potential of providing economic benefits.
