Construction method of a rock-embedded bored cast-in-place pile
The invention discloses a construction method of a rock-embedded bored cast-in-place pile. On the basis of an existing cast-in-place pile, a plurality of pick cylinder drills and roller cone drills are additionally arranged, the pick cylinder drills and the roller cone drills are reasonably and alternately used in the construction process, the advantages of the pick cylinder drills and the rollercone drills are fully exerted, and the pore-forming efficiency of the cast-in-place pile at the embedded rock section under the complex geological conditions such as hard rock stratum is effectively improved. The invention is used in the field of drilling construction.
本发明公开了一种嵌岩钻孔灌注桩的施工方法，在现有灌注桩的基础上额外配置若干截齿筒钻和牙轮筒钻，在施工过程中合理地交替地使用截齿筒钻和牙轮筒钻，充分发挥了截齿筒钻和牙轮筒钻的优点，有效提高了硬质岩层等复杂地质条件下灌注桩的嵌岩段的成孔效率。此发明用于钻孔施工领域。
