超长空心钢管嵌岩斜桩混凝土取芯技术

Concrete Core Drilling Technology for Ultra-long Inclined Hollow Steel-tube-pile Embedded in Rock

本文涉及一种超长空心钢管嵌岩斜桩混凝土取芯导向定位装置,通过对取芯检测设备进行导向定位以保证钻进垂直度的装置。

An introduction is given to a guide positioning device which leads the core-drilling detection equipment to ensure appropriate verticality of the drill rod while concrete core is taken from an ultra-long inclined hollow steel-tube-pile embedded in rock.
