Abstract

The invention discloses a pressurized type long bored pile machine and a method for drilling by means of the pile machine. The pile machine comprises a base plate (1), a main mast and a power head (4). The main mast is fixed to the base plate (1), the power head (4) is matched with the main mast, a pressurization winch (8) is fixed to the base plate (1), a pulley block is arranged between the base plate (1) and the power head (4) and the pulley block comprises a set of upper pulleys fixed to the power head (4), a set of lower pulleys fixed to the base plate (1), and steel wire ropes (9) connecting the two sets of the pulleys. The method includes the key steps of starting the pressurization winch (8), tensioning the steel wire ropes (9), increasing several times of traction of the pressurization winch (8) under the action of the pulley block and applying the traction to the power head (4) to drill up rocks. According to the pile machine and the method for drilling by means of the pile machine, drilling capacity can be improved greatly.

Description

technical field [0001] The invention relates to pile foundation construction technology in the field of civil engineering, in particular to a pressurized long spiral drilled pile driver and a drilling method using the pile driver. Background technique [0002] A traditional long auger drilled pile driver includes a chassis, a main mast, a power head connected with a long auger rod, a hoist, a traction rope, and ancillary equipment for pumping concrete. The main mast is fixed on the chassis, the power head is slidingly matched with the main mast, the top of the mast is provided with a fixed pulley, the hoist is fixed to one end of the traction rope, the traction rope goes around the fixed pulley and the other end of the traction rope is fixed to the power head. The hoist winds or loosens the traction rope, causing the power head to rise or fall along the mast. The long helix is ​​a commonly used name in the industry, that is, the long helical drill rod, which essentially mea...
