Sleeve drilling system
The embodiment of the invention provides a sleeve drilling system which comprises a sleeve used for rotary drilling, a gas ejector pipe, and an air compressor; the gas ejector pipe is fixed to the outer side of the sleeve and can rotate along with the rotation of the sleeve; the air ejecting direction of the gas ejector pipe is consistent with the drilling direction of the sleeve; the air compressor is connected with the gas ejector pipe and used for providing high-pressure ejecting gas for the gas ejector pipe; the air compressor is used for providing the high-pressure ejecting gas for the gas ejector pipe when the sleeve rotates for drilling; and the high-pressure ejecting gas ejected out of the gas ejector pipe is used for conducting cutting disturbance on a to-be-drilled soil body so that the soil body can be softened. According to the sleeve drilling system, the technical problems that in the drilling process of a traditional sleeve drilling system, side friction generated between the inner wall and the outer wall of the sleeve and a soil layer is large, and sleeve drilling is difficult are solved.
本申请实施例提供了一种套筒钻进系统，包括：套筒，用于旋转钻进；喷气管，固定在套筒的外侧且能够随着所述套筒的旋转而旋转，所述喷气管的喷气方向与所述套筒的钻进方向一致；空压机，与所述喷气管连接，用于为所述喷气管提供高压喷射气体；其中，所述空压机用于在所述套筒旋转钻进时，为所述喷气管提供高压喷射气体，所述喷气管喷出的高压喷射气体用于对待钻进的土体进行切削扰动使得土体软化。本申请实施例解决了传统的套筒钻进系统在钻进过程中，套筒内外壁与土层产生的侧摩阻力较大，套筒钻进困难的技术问题。
