Rotary drilling rig suitable for various rock stratums and foundation construction method
The invention relates to a rotary drilling rig suitable for multiple rock stratums and a foundation construction method.The rotary drilling rig suitable for the multiple rock stratums comprises an equipment body, an excavating assembly, a laser rock breaking assembly and a wall protecting and grouting assembly. Tunneling of conventional rock stratums can be achieved through the excavating assembly, tunneling of hard rock stratums can be coped with through the excavating assembly and the laser rock breaking assembly, and therefore targeted tunneling can be conducted on the rock stratums with different hardness; and meanwhile, grouting support can be formed on the inner wall of the soft rock stratum through the wall protection grouting assembly before the hard rock stratum is tunneled, the stability of the structure is improved, and collapse of the soft rock stratum during tunneling of the hard rock stratum is avoided. The problems that in the prior art, a rotary drilling rig cannot adapt to rock stratums with different hardness, so that when the rotary drilling rig meets hard rock stratums, a drill bit is seriously abraded, and soft rock stratums of pouring holes have collapse risks are effectively solved.
本申请涉及一种适用于多种岩层的旋挖钻机及地基施工方法，其中，适用于多岩层的旋挖钻机，包括：设备主体、挖掘组件、激光破岩组件和护壁注浆组件。通过挖掘组件能够实现常规岩层的掘进，通过挖掘组件和激光破岩组件能够应对硬质岩层的掘进，从而满足对不同硬度的岩层进行具有针对性的掘进，同时进行硬质岩层的掘进前可以通过护壁注浆组件在软质岩层的内壁上形成注浆支护，提高其结构的稳定性，避免了硬质岩层掘进的时候导致软质岩层处发生塌陷。本申请有效地解决了现有技术中的旋挖钻机不能适应不同硬度的岩层，导致遇到硬质岩层时，钻头的磨损严重，灌注孔的软质岩层存在塌陷风险的问题。
