地埋管地源热泵系统在喀斯特地区的钻孔施工技术分析

摘要

地埋管地源热泵系统在国内的应用地区越来越广,在喀斯特地区的应用工程也与日俱增.但是喀斯特地区地质状况较复杂,钻孔难度较大,在一定程度上阻碍了地埋管地源热泵在该地区的发展.针对喀斯特地区的地质结构,研究其特征,分析了在钻孔施工中应注意的问题,并提出了一套在喀斯特地区可行性较高、成本较低的钻孔施工技术.%Ground coupled heat pump system is more and more widely application in China, the number of projects is growing in karst district. However, geology condition is complicated and drilling is difficult in karst district, to a certain extent, these hinder the development of the ground coupled heat pump. According to the geological structure in karst district, study the commonness and characteristics, analyze the problems that should be paid attention to in the drilling, and puts forward one feasibility drilling technology in karst district.
