1、The drilling rig moves the machine to the hole position, adjust the Angle, and support the legs to the ground to ensure that there is no displacement in the drilling process;

2、Install the casing and casing drill bit, return the mud from the drill bit from the hole through the casing pipe, and drill with water to the design requirements;

3、Before injecting a certain amount of cement slurry into the casing before the anchor cable, and then put the recyclable anchor cable into the casing (to ensure the pile effect);

4、First, grouting in the pipe, connect the made slurry through the grouting pump to a grouting pipe for grouting the bottom of the hole. When the hole is completely back to the slurry, stop the grouting;

5、Pull out the casing and move the machine to the next hole;

6、After the cement slurry in the hole is initially condensed, the second grouting is carried out.
