Single-power bidirectional drilling stirring pile machine

Abstract

The invention discloses a mono-dynamics bidirectional drilling mixing pile machine, comprising a forward rotating drilling rod, a reverse rotating drilling rod, an electric motor, a framework, a mixing can, a slush pump, bit blades, and a cyclic gear train mechanism for changing directions of the forward rotating drilling rod and the reverse rotating drilling rod. The cyclic gear train is disposed on the upper portion of the drilling rod. A fixation plate for changing the cyclic gear train to an ordinary gear train is fixed on the upper portion of the mixing pile machine which does not rotating with the electric motor. The invented method implements forward and reverse bidirectional drilling and mixing of the pile machine without changing structure and operation method of the traditional mixing pile machine; and the piling speed and piling quality are enhanced.

Description

technical field [0001] The invention relates to a stirring pile driver, in particular to a single-power, two-way drilling stirring pile driver. Background technique [0002] In the construction of mixing piles in railway, highway, construction, municipal, water conservancy, and port projects, the pile driver usually uses the drill bit to rotate in one direction to drill, stir, and form piles. Slurry phenomenon occurs, the efficiency is low, and the quality is not easy to guarantee. Recent literature has shown that the use of double motors and double drill rods for bidirectional drilling and mixing has improved drilling efficiency and pile quality, but the pile machine needs to be rebuilt or remanufactured, which is costly. [0003] The Chinese patent 200720097836.3 applied by the applicant achieves single-power two-way multi-layer mixing through the epicyclic gear train mechanism, but since the epicyclic gear train mechanism is installed on the drill bit, during the pile for...

[0002]In the construction of mixing piles in railway, highway, construction, municipal, water conservancy, and port projects, the pile driver usually uses the drill bit to rotate in one direction to drill and mix. Pile, there is a slurry phenomenon, the efficiency is low, and the quality is not easy to guarantee

Recent literature shows that the use of double motors and double drill rods for bidirectional drilling and mixing improves the drilling efficiency and pile quality, but the pile machine needs to be modified or remanufactured, and the cost is high

[0003] The Chinese patent 200720097836.3 applied by the applicant realizes single-power two-way multi-layer stirring through the epicyclic gear train mechanism, but because the epicyclic gear train mechanism is installed on the drill bit, the During the pile process, the epicyclic gear train mechanism is drilled into the ground together with the drill bit. Due to the high sealing requirements of the epicyclic gear train mechanism, the structure is complicated and the cost is high, which affects the cost performance
