The difference between the rotary drilling bored pile and long spiral bored concrete pile?
The long auger rig includes two parts: hydraulic walking pile and drilling system. Pile frame adopts hydraulic walking chassis, a high degree of automation, self walking and 360 degree rotation, is equipped with four hydraulic legs and a walking cylinder to aid in walking and turning at the same time increase the overall stability in construction, can machine transfer. Column for folding box type column, flange connection, column by using two pieces of high thickness mask and bending technology of large bending machine, the two welding seam welded and column inside every 60cm welding of four reinforcing ribs fixed, increasing column torsion bending resistance. The column is controlled by two variable pressure hydraulic cylinders to take off and take off. The drilling system comprises a power head and the output shaft of the power drill head and screw drill is hollow, pile machine into a long spiral hole, drill pipe through the center of the concrete or mud pump] {concrete CFG pile construction, which can be a drilling machine once completed, can also be used to dry hole grouting, altering tool can also be taken deep mixing a variety of Engineering construction.
Rotarydiggingmachine, also known as rotary drilling rig. The utility model is a tool for road traffic and high-rise building construction. The rotary drilling rig is a kind of comprehensive, it can use the short helix bit dry digging, can also be used in wet digging rotary drill mud case. Rotarydiggingmachine with hammer drill hole digging work pieces after hard formation. If the enlarged head drilling tool is used, the reaming operation can be carried out at the bottom of the hole. Rotary digging machine adopts multi-layer telescopic auxiliary drilling drill pipe, less time, low labor intensity, without mud circulation deslagging, cost saving, no pollution, infrastructure construction is especially suitable for the construction of the city.
The difference between the rotary drilling bored pile and long spiral bored concrete pile is the main construction machinery, the hole is not the same. Long spiral for small diameter bored pile, more than 800 of the use of rotary excavation.
