1. Diameter: The diameter of the spiral pile is one of the important factors that determine its design and is usually expressed in millimeters (mm). The spiral pile pattern can be confirmed by measuring its diameter at its widest point.
2. Wall Thickness: The wall thickness of the spiral pile refers to the thickness of the wall of the spiral pile and is also one of the important components of the model. Wall thickness is usually expressed in millimeters (mm). When measuring the diameter of the spiral pile, the wall thickness may be measured accidentally.

Small hydraulic auger drill is also called small hydraulic pile auger. This machine is suitable for operapiling and drilling engineering operations such as construction, roads and bridges, electric power and greening. .
Power comes from the engine of the moving vehicle. Its structure consists of: hydraulic oil pump, four stabilizers, mast, power head, afterburner/lifting pulley, drilling tools and hydraulic operating system.
Structure and operating principle.
Hydraulic oil pump: This is a double connection type. The large displacement pump powers the powerhead, and the small displacement pump powers the four outrigger cylinders, the lift mast cylinder, and the afterburner cylinder/lift pulley.
Four stabilizers: composed of hydraulic cylinders and fixed frames. The level of the machine body can be adjusted on the job site to support and stabilize the machine body.
Mast: It is a frame structure welded by a combination ofgiant steel pipes, channel steel and angle steel. The inner grooves of the channel steel on both sides are used as a rail for the powerhead operation. from top to bottom to ensure the verticality of the drilling. The raising and lowering of the mast is completed by hydraulic cylinders.
Drive head: It adopts the gear reduction box mechanism. There is a chuck with a large hole in the middle of the low speed shaft. The upper opening of the chuck can be connected to the pipe interface. concrete pouring equipment for pouring concrete; the chuck. The bottom port connects the drill pipe and the bit through the flange.
The working principle of this machine: the power head drives the spiral blade drill rod and the bit rotating, and the drilling is carried out under the downward force of the booster pulley /lifting. During rotation, part of the material present in the layerThe soil is transported to the ground along the spiral blades.
Another part of the floor material is sandwiched between the boards. After drilling to a sufficient depth, the drilling tool is lifted by the pulley, and the material is also lifted. By changing the diameter of the auger, pile holes of different diameters can be drilled.
