Horizontal drilling rotary jet grouting pile-forming device and construction method thereof
The invention relates to the field of geotechnical engineering construction, and discloses a horizontal drilling rotary jet grouting pile-forming device which comprises a walking mechanism, an azimuth angle adjusting mechanism, a height elevation angle adjusting mechanism and a rotary jet grouting mechanism, and the rotary jet grouting mechanism comprises a sliding frame, a front power head, a wall protection sleeve, a rear power head, a drill rod and a drill bit. A front power head and a rear power head are connected to the sliding frame in a sliding mode, the front power head is detachably connected with a wall protection sleeve and used for driving the wall protection sleeve to move in the front-back direction, the rear power head is detachably connected with one end of a drill rod, the rear power head is used for driving the drill rod to rotate and move in the front-back direction, and the drill rod and the wall protection sleeve are coaxially arranged. The other end of the drill rod is detachably connected with a drilling bit or a grouting bit. In addition, the invention further discloses a construction method based on the device. According to the method, the drilling hole can be effectively prevented from collapsing, the slurry abandoning amount in the construction process is reduced, the pile forming quality is stable, and the pile diameter meets the design requirement.
本发明涉及岩土工程施工领域，公开了一种水平钻进旋转喷射注浆成桩装置，包括行走机构、方位角调节机构、高度仰角调节机构和旋喷注浆机构，旋喷注浆机构包括滑架、前动力头、护壁套管、后动力头、钻杆和钻头，滑架上滑动连接有前动力头和后动力头，前动力头可拆卸连接有护壁套管，前动力头用于带动护壁套管沿前后方向移动，后动力头可拆卸连接有钻杆的一端，后动力头用于带动钻杆自转和沿前后方向移动，钻杆与护壁套管同轴心设置，钻杆的另一端可拆卸连接有钻进钻头或注浆钻头，此外本发明还公开了一种基于上述装置的施工方法。本发明能够有效防止钻孔坍塌，降低了施工过程中的弃浆量，本发明成桩质量稳定，桩径满足设计要求。
