Construction technology
The background is equipped with a 75 grouting pump and a cement mixing bucket
1、Move the machine to the hole position.
2、Adjust the vertical Angle of the machine to good the hole position.
3、Connect the drill pipe, open the water pump, and drill to the required hole depth.
4、Remove out of the drill pipe, take the made anchor rod into the hole with a secondary wire rope.
5、After the first pressure grouting, the hole is completely returned to stop the grouting.
6、After primary coagulation of grouting, secondary high pressure grouting is carried out with high pressure grouting pipe.
