As shown in fig. 1-11, the invention provides a long auger drill, which comprises a body 1 and a power head 4, wherein the power head 4 is connected with a drill rod 5 and is used for driving the drill rod to rotate around the axis of the power head 4, a drill bit 51 is arranged at one end of the drill rod 5, and a mud scraping device for cleaning the drill rod 5 and/or the drill bit 51 is arranged at one side of the drill rod 5. The drilling machine further comprises a stand column 3, wherein a protective cylinder 6 is installed on the stand column 3, and a mud scraping device used for cleaning the drill rod 5 and/or the drill bit 51 is arranged on one side of the protective cylinder 6.
The mud scraping device is provided with a connecting seat 61 installed on the protective cylinder 6, a support 62 is connected to the connecting seat 61, and a rack shaft sleeve 621 is connected to the support 62.
The mud scraping device is further provided with a rotating support 64, a rotating support sleeve 641 is fixedly connected to the rotating support 64, the rack shaft sleeve 621 and the rotating support sleeve 641 are hinged to each other through a hinge rotating shaft 65, and then the rotating support 64 can rotate around the hinge rotating shaft 65.
The rotating bracket 64 is provided with a blade rotating shaft 66, the blade rotating shaft 66 is provided with a blade 661 for scraping mud, and the blade 661 can rotate around the rotating shaft 66.
Since the connection base 61 is a stationary part, it is generally fixedly installed on the casing 6, and it is connected with the casing 6 by a bolt. The bracket 62 is formed by welding angle iron, channel steel and steel plates, supports the whole mud scraping device, and is also fixedly connected with the connecting seat 61. The rotating bracket 64 is used to support the blades 661 and is fixedly connected thereto so that the action between the rotating bracket 64 and the blades 661 is maintained in unison. And the frame shaft sleeve 621 and the rotating bracket sleeve 641 are hinged with each other, and the rotating bracket sleeve 641 is arranged on the rotating bracket 64 to keep the same action with the rotating bracket 64, and similarly, the frame shaft sleeve 621 keeps the same action with the bracket 62, that is, the blade 661 and the bracket 62 have a moving relationship, so that the position relationship between the two is changed, and further, the position relationship between the blade 661 and the drill rod 5 and the drill bit 51 can be adjusted.
The rotating bracket 64 is also hinged with a connecting rod 67, and the blade 661 on the rotating bracket 64 can be moved by pushing the connecting rod 67, so that the position relation between the blade 661 and the drill rod 5 and/or the drill bit 51 can be adjusted.

The main winch 12 and the auxiliary winch 13 are further installed on the body 1, and the main winch 12 or the auxiliary winch 13 drives the steel cable to pass through the top pulley block 32 so as to lift the drill rod 5.
The legs 11 are used to support the whole body 1 at a certain longitudinal distance from the ground, and the distance between the body 1 and the ground can be adjusted by the leg cylinders a 10. The chassis 111 is disc-shaped and used for enlarging the contact area with the ground, so that the chassis is not sunk into the ground on soft ground, and the instability of the whole machine is avoided. The main hoist 12 and the auxiliary hoist 13 are driven by the hoist motor a18, and the main hoist 12 and the auxiliary hoist 13 output power to the pressurizing winch 8 again, so that it can lift the drill rod 5.

The power head 4 can slide on the guide rail 31 and can follow the position of the drill rod 5 in real time.
The fuselage 1 is also provided with a counterweight 14 and a cab 15.
When the spiral drilling machine is used, the spiral drilling machine is firstly installed in place, then the location work is carried out on the place needing drilling, then the rotation mechanism 7 is used for driving the machine body 1 to rotate, the translation motion of the machine body 1 is carried out, the two actions move the drill rod 5 to the preset position, and the work is stopped after the adjustment is carried out in place. The power head 4 is then activated, the power head 4 typically rotating a gear reduction motor as a power source to drive the rotational movement of the drill pipe 5, while driving the pressurized winch 8 to power the axial movement of the drill pipe 5. Meanwhile, when the drill rod 5 is lifted after drilling, the blades 661 on the mud scraper clean the drill rod 5 and the drill bit 51, and after cleaning is finished. The above work flow can be entered again until the operation is finished.
In drilling, the following process may also be followed. Long spiral drilling machine is in place → drilling (according to whether the geological condition is pressurized) is → drilling to the designed depth → hole bottom cleaning → pulling and simultaneously pouring concrete → drilling machine is moved → reinforcing cage is put → vibration → piling is carried out.
The long spiral drilling machine is in place: when the long spiral drilling machine is in place, the long spiral drilling machine must be kept stable and does not incline or displace, and in order to accurately control the drilling depth, a control scale is required to be made on a machine frame or a machine pipe so as to carry out observation and recording in the construction process.
Drilling: the column 3 is straightened, the pile position is aligned (by using the alignment ring), the machine is started to drill and unearth, and the pressurizing system is started according to the geological condition. And stopping drilling after the designed depth is reached.
And (6) cleaning soil at the bottom of the hole. After the hole is drilled to a preset depth, idle rotation soil cleaning is carried out at the bottom of the hole, and then the rotation is stopped; the drill rod 5 is lifted without the drill rod 5 being bent. The soil scattered on the ground during the drilling process must be removed at any time.
Construction in winter and rainy period:
(1) in winter, when the temperature is lower than 0 ℃ and the concrete is poured, heating and heat preservation measures are adopted. And when pouring, the temperature of the concrete is executed according to the specification of the winter implementation scheme. The pile top can not be frozen until the design strength is not 50%. When the temperature is higher than 30 ℃, the concrete is subjected to retardation measures according to specific conditions.
(2) In the rainy period, the regulation of pouring concrete along with drilling is strictly adhered to, so that the phenomenon that holes collapse due to water irrigation after the holes are formed in a rainy day is prevented. Drilling construction cannot be performed in rainy days. On site, various measures for drainage are needed to prevent the ground water from flowing into the groove so as to avoid slope collapse or foundation soil subsidence, inclination of a drilling machine and the like.
Meanwhile, the above embodiments of the present invention are only used for illustrating the technical solutions of the present invention, and are only examples of the technical solutions of the present invention, and are not used to limit the technical solutions of the present invention and the protection scope thereof. Modifications of the technical solutions disclosed in the claims and the specification by equivalent technical means, equivalent devices and the like should be considered as not exceeding the scope of the claims and the specification of the invention.
