Pump suction reverse circulation pile foundation construction device and method
The invention discloses a pump suction reverse circulation pile foundation construction device and method and belongs to the technical field of pile foundation construction. The pump suction reverse circulation pile foundation construction device comprises a rotary drilling rig, a reverse circulation gravel pump, a slag suction hose, a mud purification device, a settling pond and a circulating pool which are communicated in sequence; the rotary drilling rig comprises a drill bit, a drill pipe, a transmission rod, a rotating disk and a hydraulic motor, the drill bit is connected with a bottom flange of the drill pipe, the top end of the drill pipe is connected with a bottom flange of the transmission rod, the top end of the transmission rod penetrates through the rotating disk and is fixed, the top end of the transmission rod is connected with one side of the reverse circulation gravel pump through a swiveling union, the joint of the reverse circulation gravel pump and the slag suction hose is provided with a faucet, and the slag suction hose is fixedly connected with the faucet and the mud purification device. The construction method includes the first step of forming reverse circulation, the second step of starting drilling after reverse circulation is formed until a pile hole is formed and the third step of conducting hole cleaning construction after the pile hole is formed. The device reduces the power of the gravel pump and improves hole forming efficiency.
