高铁岩溶地段钻孔桩施工技术

Construction Technology of Bored Pile in Karst Section of High-speed Railway

随着经济和交通的快速发展,桥梁的修建越来越多。由于岩溶地区地质、水文条件错综复杂,因此其在施工期间往往会伴有诸多不可预见的因素,桩基施工条件复杂,稍有不慎就会造成卡钻、钻孔偏斜等安全质量事故,因此岩溶地区的柱基施工必须采取充分可靠的施工技术措施。基于此,本文以工程实例为背景,并重点围绕高铁岩溶地段的钻孔桩施工技术展开探讨,通过阐述具体的应用要点,确保高铁岩溶地段钻孔桩的施工质量,为高铁岩溶地段提供更好的施工保障。

With the rapid development of economy and traffic,more and more bridges are built.Due to the complex geological and hydrological conditions in karst areas,there are many unforeseen factors in the construction period,the construction conditions of pile foundation are complex,and a little carelessness will lead to safety and quality accidents such as sticking of drill pipe,deviation of drilling hole,etc,therefore,the reliable construction technical measures must be taken in the construction of column foundation in karst area.Based on this,this paper take the engineering example as the background,and focuses on the bored pile construction technology of the karst section of high-speed railway,through the elaboration of specific application points,ensure the construction quality of bored pile in karst section of high-speed railway,and provide better construction guarantee for karst section of high-speed railway.
