Embodiment Construction

[0046] The present invention will be described in further detail below in conjunction with the embodiments of the drawings.

[0047] Such as figure 1 As shown, the hydraulic reaming circulation drilling rig (HRCR drilling rig) in this embodiment includes a pile machine body 1, a mast 2, a mast support mechanism 3, a faucet 4, a hydraulic device 5, a drill rod, a power head 7, and a reaming drill 8. Main components such as pulley block, lifting rope, crawler chassis 10. The HRCR drilling rig is equipped with a visual control system, which can display real-time reaming depth, reaming diameter, reaming cylinder stroke, power head rotation speed; dynamic display of the reaming process; monitoring the current of each motor of the rig, high mechanical automation, reducing labor demand And effectively reduce the probability of safety accidents.

[0048] Among them, the crawler chassis 10 is installed on the bottom of the pile driver body 1, the mast 2 and the mast support mechanism 3 are...

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 circulation drill and a reaming pile construction process. Background technique [0002] In the construction of high-rise and super high-rise buildings, piling is required. There are various types of piling machines in the prior art, such as the Chinese utility model patent with the patent number ZL 99237847.8 (authorized announcement number CN 2375670 Y) "Multifunctional Pile Driver", this multifunctional pile driver is composed of upper and lower chassis, tower, strut, drill rod, drilling tool, lifting and lowering device and supporting structure. 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 with the patent number ZL201120217172.6 (Authorized Announcement Number CN 202131986 U). The pile driver includes the main body of the pile driver. The main body is provided with a mast an...
