Long auger is a type of equipment commonly used in construction machinery, with a high utilization rate. Its application range is extensive.Auger drillingThe use of drilling machines is very extensive, which can meet the needs of bridge construction and high-rise building engineering. Currently, rotary drilling machines are widely used in engineering construction for drilling and grouting. With the widespread use of this equipment, the selection and proper operation of auger drills, as well as the use of long auger drills, have become major concerns for every user.

Auger bit selection

Correct operation and use of long auger

There are four types of auger bits according to their properties and functions. Therefore, appropriate bits should be selected according to their properties and functions. Relative to traits, it mainly includes:

One is the pointed bottom drill, which is suitable for a cohesive soil layer. It can insert and weld cemented carbide cutter head on the edge, and drill hard soil and frozen soil.

The second is the flat bottom drill, which is suitable for slack soil layer.

Third, rake bit, which is suitable for miscellaneous fill soil layer rich in many bricks and tiles.

Fourth, the barrel drill bit is suitable for drilling concrete blocks, strip stones, and other obstacles, but when in use, the thickness of each drilling should be less than the height of the barrel body, and water should be added to cool it properly during drilling.

In terms of function, it is divided into four types: the first is the core auger bit, which is suitable for gravelly soil, medium hardness rock, and weathered rock stratum. The second is the core bit, which is suitable for weathered rock stratum and cracked rock. The third is the single floor soil layer drilling bucket, which is suitable for the construction of the clay layer and dry hole. In addition, there is a rotary drilling bucket with a double bottom, which is suitable for the operation of quicksand layer, sandy soil, and pebble layer with poor cementation and small particle size. Under the condition of wet hole drilling, the use of a double bottom rotary drilling bucket can also be conducive to the hole cleaning construction at the hole bottom.

The function of each kind of auger bit is different, so we should choose it differently.

For the scientific operation and use of long auger drilling rig, the requirements for operators are stricter. Never drink alcohol or take medicine before operation. Do not do anything that affects the normal operation of the auger drill.

Auger drill operators must pass practical inspections and work with certificates from their perspective.

Second, the auger shall meet the construction needs. Before formal drilling, the trial operation test shall be carried out first, and the equipment inspection application form shall be submitted to the supervision unit in time. At the same time, the key points of drilling treatment in the construction of spiral drilling rig shall prepare specific drilling process operation instructions, and carry out skill disclosure level by level. There shall be operating procedures for mechanical equipment, and the drilling process shall be well recorded.

Third, do not turn or move the drill pipe until the planned elevation is reached in the drilling process. If it is necessary to turn or move the drill pipe under special circumstances, it is essential to raise the drill pipe to the surface promptly, clean and close the drill bit valve. The operator must carefully control the auger drill to decrease the speed and rotation rate. For every full rotation of the auger drill thread, the drill bit should decrease by one pitch to maintain alignment.

In addition, before drilling, first carefully check whether the air hole at the top of the core pipe is smooth, whether the concrete delivery hose has excellent joints and whether there are signs of misunderstanding. In the process of hole forming, if the drill pipe shakes or the footage is slow, wait for the footage slowly to avoid the deflection and displacement of the pile hole and the damage of the drill pipe and drilling tool.

Up to now, Zhejiang Hengyue Machinery Co., Ltd. has gone through 12 years of R & D and production experience in the field of.drillingDrill and spiral bit industry.

Since 2012, a professional R & D team has been established from basic assembly and market practice, which can design new products according to customers' ideas. We mainly supply soil drill, manual soil drill, ice drill, ice fishing drill, artisan Mini cultivator, manual scoring machine, ground drill, etc.
