溶洞处理采芯率和泥浆漏失的施工技术应用

Application of Caving Treatment Rate and Mud Leakage in Construction Technology

本文结合工程实例,根据勘察钻探资料、设计原则和现场实际钻孔资料,通过对溶洞采芯率达不到要求和钻孔泥浆漏失的主要原因进行分析及针对性的处理,有效地保证了溶洞处理的完整性,确保质量控制和经济效益,为同类岩溶区域基坑溶洞处理施工提供借鉴。

In this paper,combining with the engineering example,according to exploration drilling data,design principles and actual drilling data,through the cave the core rate of less than the requirement and the main cause of drilling mud loss is analyzed and the cor- responding processing,effectively guarantee the integrity of karst cave treatment,ensure quality control and economic benefit,as with the karst area foundation pit cave treatment construction to provide reference.
