The invention relates to a frequency oscillation pile casing type drilling machine for a cast-in-place concrete pile. The frequency oscillation pile casing type drilling machine comprises a lifting lug and a low frequency oscillator, wherein the low frequency oscillator is connected to the upper end of a motor through a water inlet steel pipe; the upper end of the water inlet steel pipe is connected with a high-pressure water inlet pipe; the lower end of the water inlet steel pipe is provided with two high-pressure water inlet branch pipes; the lower ends of the high-pressure water inlet branch pipes are provided with water jet steel pipes; the lower ends of the water jet steel pipes are provided with jet nozzles; a pile casing is fixed on a shell at the lower end of the motor, and is cylindrical; the lower end of the pile casing is provided with a cutting edge, and the upper end of the pile casing is provided with an upper cover; the upper cover is provided with an overflow hole; the lower end of a motor output shaft is provided with a drill rod; the lower end of the drill rod is provided with a drill bit; the drill bit is arranged in the pile casing; and the pile casing and the cutting edge are higher than the drill rod and the drill bit. Rapid drilling is performed by enlarging jet flow, and the low frequency oscillator vibrates into the pile casing and is used for driving the drill bit to sink together with the motor, so that drilling is rapid, and hole walls are smooth and regular.
Description
1. Technical field [0001] The invention relates to a drilling machine, in particular to a frequency-vibration casing-type drilling machine for concrete pouring piles. 2. Background technology: [0002] The well-known common sense is: in drilling in soft ground, increasing the jet flow can significantly increase the drilling speed, but increasing the jet flow will cause serious hole reaming and hole wall collapse. 3. Contents of the invention: [0003] The present invention overcomes the above disadvantages and provides a casing-type drilling machine with frequency vibration. [0004] The present invention is achieved through the following technical solutions: [0005] A frequency-vibration casing-type drilling machine, including lifting lugs and a low-frequency vibrator, the low-frequency vibrator is connected to the upper end of the motor through a water inlet steel pipe, the upper end of the water inlet steel pipe is connected with a high-pressure water inlet pipe, and ...
