Bored pile drilling is a type of construction equipment used to make pile holes in the construction industry of concrete pile or cement mortar (ie take the soil from the ground to form pebbles) by drilling.
Pile Drill Pipe Drill (Twist): When drilling in the ground, the drill bits work like wood or steel drills, pushing the soil through the twist. There are also drills of chicken intestinal drum, spiral cage and row (three noses), used for drilling to form barrette piles and reinforcement walls reinforced foundation (wall made using this device in the form of a row of circular cross-sections planted in succession).
Pile drilling machine (digging bucket): At work, the drum is rotated by drilling rigs, cut to the ground, stuffed into a bucket, then the soil in the digging bucket is brought up with the dig by the withdrawal drill up
Borehole reciprocating drilling machine: ship propeller blade (ie, propeller type) drilled into the soil by attaching to the head of the drilling rigs, is the pump, rotary. Once the soil has been dredged into a drill, the pump is suctioned to a large capacity, pumped onto the ground with the solution kept in the hole through the drilling line.
* Construction of bored pile drilling machine
Pile drilling machine drum type digging drilling system includes (drum) and drill head (drilling bucket). The whole system is usually fitted to a crawler crane weighing between 30 and 80 T, mainly using a hydraulic engine called a boring machine. [Nbsp] For standard machines such as BAUER, There are many types of bored pile drills, but the most common ones in Vietnam are manhole drilling rigs. These drills provide the quality of well bored piles, drilling large piles that can not be drilled by drilling machines. Rock drill at high solids.

Drills made of steel with 3 to 5 interconnected segments such as antenna pole, length from 12 m to 18 m. When drilling the inside segments protrude until the five sections are complete, the drilling depth is from 30 m to 64 m. The drilling consists of two types of friction and locking. For each geological type that uses these needles.
Bucket drills with diameters ranging from 600 mm to 3,000 mm or more. Pile drilling machines used in Vietnam are listed by HITACHI, NIPON, SUMITOMO and so on. As a Japanese manufacturer of crawler cranes. Currently, large projects requiring high technology and good pile quality have used higher-tech mast boring machines, greater drilling capacity and drilling of the thinnest geothermal drilling sites. can not drill. BAUER bored pile brand has confirmed the quality and brand name in Vietnam when drilling large projects such as Vung Ang Thermal Power Plant, Hanoi - Lao Cai Expressway Project, Petrovietnam Hotel Building with a diameter of 2000m deep, 80m deep.
