Unequal-depth weathered rock stratum MJS high-pressure jet grouting pile all-directional construction method
The invention discloses an unequal-depth weathered rock stratum MJS high-pressure jet grouting pile all-dimensional construction method which comprises the following steps of 1 range determining, 2 drilling machine positioning, 3 construction sequence determining, 4 jet grouting pile position setting, 5 construction temporary control net building, 6 slurry preparation, 7 high-pressure jet grouting trolley in-place, 8 drilling, 9 drill bit replacement, 10 test jet grouting, 11 high-pressure jet grouting operation, 12 machine tool cleaning and 13 pile machine displacement. According to the construction method, the high-pressure jet grouting pile machine is improved and adapts to hole guiding in the rock layer, the pile forming quality of the unequal-depth high-pressure jet grouting piles in the weathered rock layer is achieved, the pile length of the jet grouting piles and manual and mechanical input are reduced, the construction period is shortened, the pile forming quality of the unequal-depth high-pressure jet grouting piles in the weathered rock layer is further achieved, and the effects of effective water stopping, water retaining and the like are achieved. The high-pressure jet grouting piles with different lengths are selected or the high-pressure jet grouting piles are adopted on the inner side and the outer side at the same time according to the water content of different soil layers in a local section, the water stopping effect is achieved, and the application effect is good.
本发明公开了不等深风化岩石层MJS高压旋喷桩全方位施工工法，包括以下工法步骤：1确定范围、2钻机定位、3明确施工顺序、4设定旋喷桩位置、5建立施工临时控制网、6浆液制备、7高喷台车就位、8钻孔、9更换钻头、10试喷、11高压喷射注浆作业、12机具清理、13桩机移位，本施工工法通过对高压旋喷桩机改进，适应岩石层中引孔，实现了不等深高压旋喷桩在风化岩石层中的成桩质量，减少了旋喷桩桩长及人工与机械的投入，缩减工期，还实现了不等深高压旋喷桩在风化岩石层中的成桩质量，得到了有效止水，局部区段根据不同土层含水率，选择不同长度的高压旋喷桩或者内外侧同时采用高压旋喷桩，已达到止水效果，应用效果好。
