Precautions for Use of Drill Pipe of Rotary Digger? Drill pipe and drill bit can only be used for drilling pile hole, and are not allowed to be used for soil transfer, handling or leveling of construction site. Never immerse the drill in liquid concrete. The drilling operation can only be started when the drill bit touches the bottom of the hole. When drilling into sand layer or pebble layer, the driver should pay special attention to it. When drilling, the footage should not be too deep at one time. Otherwise, the hole wall will shrink, so that there will be no gap between the barrel wall of the drill bit and the hole wall, which will cause the drill bit to fail to reverse or lift, causing major accidents such as sticking. According to the geological environment, to select the appropriate drilling bucket. Selection of suitable and geological requirements of the drilling bucket, both to improve the work
Precautions for Use of Drill Pipe of Rotary Digger? Drill pipe and drill bit can only be used for drilling pile hole, and are not allowed to be used for soil transfer, handling or leveling of construction site. Never immerse the drill in liquid concrete. The drilling operation can only be started when the drill bit touches the bottom of the hole.
When drilling into sand layer or pebble layer, the driver should pay special attention to it. When drilling, the footage should not be too deep at one time. Otherwise, the hole wall will shrink, so that there will be no gap between the barrel wall of the drill bit and the hole wall, which will cause the drill bit to fail to reverse or lift, causing major accidents such as sticking.
According to the geological environment, to select the appropriate drilling bucket. The selection of drilling bucket suitable for geological requirements not only improves the work efficiency, but also avoids the occurrence of major accidents of buried drilling and sticking drilling.
When using the drill pipe of the rotary excavator, the following steps should be followed to improve the service life of the drill pipe of the rotary excavator. The following is a specific understanding.
1. Stop the lifting action of the main hoist immediately to prevent the drill pipe from opening itself during the lifting process. The unlocked drill pipe may slide down freely and cause the rod to fall. The loss of the falling rod is very serious, and it is possible to scrap the entire drill rod and pile hole.
2. Slowly drop the drill pipe into the bottom of the borehole again, reverse the drill pipe, and then put out the drill pipe after it is unlocked.
3. Remove the drill pipe for inspection after pouring the soil.
4, open the drill pipe, the drill pipe for a thorough inspection and repair.
Finally, it is reminded that when drilling, the footage should not be too deep at one time, otherwise the hole wall will shrink, so that there will be no gap between the drill barrel wall and the hole wall, resulting in the drill bit being unable to reverse or lift, resulting in major accidents such as sticking.
