Abstract

The invention discloses a hydraulic reaming circulation drilling machine. The hydraulic reaming circulation drilling machine comprises a pile machine main body, and a mast and a mast support mechanism which are installed on the pile machine main body, and is characterized in that a faucet is installed on the upper end portion of the mast, a hydraulic device which can transmit hydraulic pressure to the faucet is fixedly connected with the bottom of the faucet, a drill rod which can transmit hydraulic pressure to the hydraulic device is fixedly connected with the bottom of the hydraulic device, a power head which drives the drill rod to rotate is installed on the lower end portion of the mast, and a reaming drill bit which performs hydraulic reaming under action of the hydraulic device is installed at the bottom of the drill rod. The invention further discloses a reaming pile construction technology of the hydraulic reaming circulation drilling machine. The hydraulic reaming circulation drilling machine and the reaming pile construction technology thereof have the advantages of 1, achieving integration of drilling, reaming and hole cleaning, and being high in construction efficiency; 2, being stable and reliable in reaming action, and high in efficiency by using the reaming drill bit driven through the hydraulic pressure; 3, performing the slurry circulation hole cleaning in the reaming, and achieving good reaming quality; 4, being strong in reaming ability, and enabling the maximum reaming diameter to reach above 2m.

Description

technical field [0001] The invention relates to a pile driver, in particular to a hydraulic reaming circular drilling machine and a construction process for reaming piles. Background technique [0002] In the high-rise and super high-rise building construction process, all need to carry out piling, there are various pile drivers of different structures in the prior art, as disclosed by the Chinese utility model patent that the patent No. is ZL 99237847.8 (authorization announcement number is CN 2375670 Y) "Multifunctional pile driver", the multifunctional pile driver is composed of upper and lower chassis, tower, strut, drill pipe, drilling tool, lifting device and support frame, the multifunctional pile driver is easy to use and low in cost . Another example is the "pile driver" disclosed in the Chinese utility model patent whose patent number is ZL201120217172.6 (the authorized announcement number is CN 202131986 U). There is a millstone faucet on the side of the millsto...
