XPB-20B jet grouting pile full hydraulic walking, Weight: 2.8t can be accessed drill length: 3 meters can be equipped with drill types: single-tube double pipe three jet grouting drilling rig, the process is as follows: start pile driver while opening the high-pressure mud pump low pressure conveying cement slurry, so the drill pipe stands to move along the guide, the jet into a sink hole; until the pile bottom design elevation, observation should not exceed the current rating. High Pressure Churning Pile machine safety operation 1, machine operator must carry operation certificate, operations area shall be clearly marked and enclosure. 2, when the crew for climbing inspection and maintenance, must wear seat belts, tools and other items should be placed in kits, high-altitude operations personnel shall not arbitrary parabolic downward. 3, away from the job site power transformers or power from the main line should be less than 200m, lifting startup voltage shall not exceed 10% of the rated voltage. The motor and the control box should have good grounding. 4, machine should be placed on a smooth, solid, and fine-tune adjust drill, triple pipe jet grouting rig type, so that it remains vertical 5 should be checked and confirmed before the start of each component is connected securely pile, tightness of the belt properly, gearbox within the oil level compliance. 6, before the start, should the joystick in neutral position; after the start, should short test run, check the meter, temperature, sound, braking and other work before the job is normal. 7, boot, sun triple pipe jet grouting rig should be sent to the slurry after drilling; shutdown, you should first stop after stop drilling slurry. Mud pump should not be left unattended, the quality of the mud and slurry surface height measurements and adjustments should be ready, track triple pipe jet grouting rig to ensure a suitable concentration. When the stop drilling, jet grouting rig triple tube manufacturers, appears to be leaking slurry should be added, and should be kept clean of debris sedimentation tank, holding the mud pure. 8, construction pile driver should always observe the functioning of the pile, when an exception occurs, should immediately stop inspection, troubleshooting before continuing after construction. 9, before grouting, check the high-voltage equipment and management systems, seals must be intact and must not have debris in each pipe and nozzles. 10, when the pile driver job control air compressor, pump delivery pressure and stripping tube, spraying speed.
