Jet grouting pile grouting construction process for underground shaft reinforcing
The invention provides a jet grouting pile grouting construction process for underground shaft reinforcing, and relates to the field of jet grouting pile grouting processes. The jet grouting pile grouting construction process for underground shaft reinforcing comprises the following steps that S1, a drilling machine is in place, wherein the drilling machine needs to be flat placed on the firm andsolid ground beside a construction site drilled hole, and a drill rod of the drilling machine is aligned to the center of a hole site; and S2, a pipe is tripped into the drilled hole, wherein a grouting pipe is subjected to jetting testing firstly, the jetting condition of grouting pipe high-pressure water and compressed air is checked, whether sealing rings at all positions are closed or not is checked, then the drilling machine is started, the drill rod starts to drill the hole downwards, the grouting pipe is inserted downwards while the hole is drilled, low-pressure water is conveyed to theinner end of the grouting pipe in the pipe tripping process at the same time for flushing the hole and being sprayed downwards. According to the jet grouting pile grouting construction process for underground shaft reinforcing, the problem that an existing jet grouting pile grouting pipe is likely to be blocked, and forming of the bottom of a jet grouting pile is incomplete is solved, the construction rate is increased, and the construction cost is reduced.
本发明提供一种用于暗挖竖井加固的旋喷桩注浆施工工艺，涉及旋喷桩注浆工艺领域。该用于暗挖竖井加固的旋喷桩注浆施工工艺，包括以下步骤：S1.钻机就位：将钻机需平置于施工现场钻孔旁牢固坚实的地面上，将钻机的钻杆对准孔位中心；S2.钻孔下管：先对注浆管进行试喷，检查注浆管高压水与压缩空气喷射情况以及各部位密封圈是否封闭，然后启动钻机，让钻杆开始向下钻孔，一边钻孔一边向下插入注浆管，下管过程中同时箱注浆管内端输送低压水冲孔喷下。本发明提供一种用于暗挖竖井加固的旋喷桩注浆施工工艺，该工艺解决了现有旋喷桩注浆注浆管容易堵塞、旋喷桩底部成型不完全的问题，加快了施工的速率，减少了施工成本。
