The cofferdam project is a large-aperture pile hole construction plan. 1000mm and 1200mm diameter casings need to be inserted into the rock formation for 5-6 meters, the total depth of the pile holes is 25-30 meters, 300 piles with a diameter of 1200mm, and 280 piles with a diameter of 1000mm. This solution is expected to allow the port to obtain a load capacity of 500,000 tons, thereby increasing the throughput of the Chulai port.

Spherical tapered button bit Features
Ball-tooth tapered button bit has the characteristics of long service life, accurate positioning, coarse cuttings, low dust, durability and no need for grinding, etc. Compared with the traditional flaky tapered button bit, the drilling speed is faster, and the ball-tooth bit is passivated. Long, its non-grinding life is about 5-6 times that of the tapered button bit of the same diameter blade head, which is conducive to saving auxiliary man-hours, reducing manual labor of workers and speeding up engineering. Therefore, tapered button bit with taper connection and threaded connection of different diameters is widely used in various hard and brittle rocks with drilling rigs.

The ball-tooth drill bit is composed of cemented carbide column teeth inlaid on the drill bit body. Compared with the chip drill bit, the ball tooth drill bit has free tooth arrangement, and the number and position of the edge and middle teeth can be reasonably determined according to the diameter of the chisel hole and the size of the rock breaking load, and the diameter of the drill bit is not limited. And because it is multi-point crushing, the rock-breaking efficiency is higher, which can effectively eliminate the blind area of rock-breaking and avoid the repeated crushing of cuttings. Its non-grinding life is longer and the regrinding workload is small. It shows high value under the operating conditions of rock trolley and deep hole mining.
