Beschreibung
Zusammenfassung:	The invention discloses an ultra-deep filling drilling construction method. According to the method, ultra-deep filling drilling can be rapidly constructed, the section of a shaft is formed through one-time construction, one-hole multi-pipe design is adopted, the drilling utilization rate is increased, a traditional filling drilling construction and pipeline layout mode is broken through, and short-term rapid construction of ultra-deep drilling is achieved. 本发明公开了一种超深充填钻孔施工方法，该方法能够快速施工超深充填钻孔，井筒断面一次施工成型，采用1孔多管设计，提升钻孔利用率，打破传统充填钻孔施工和管道布局方式，实现超深钻孔短期快速施工。
