Product Description

Product Description

The rotary drilling rig as a hydraulic rotary piling rig is a kind of construction machine suitable for hole
formation in building foundation engineering comprehensive drilling rig, which can use a variety of bottom
layers, and has the characteristics of fast hole forming speed, less pollution, and strong maneuverability.
The short auger bit is used for dry excavation, and the rotary bit can also be used for wet excavation in the
case of mud retaining walls. The rotary drilling machine can cooperate with the hammer to drill through the
hard formation and then carry out the digging operation. If it is matched with the expansion head drill, the
hole reaming operation can be carried out at the bottom of the hole. The rotary piling rig adopts multi-layer
telescopic drill pipe, which has less auxiliary drilling time, low labor intensity, no need for mud circulation
and slag discharge, which saves costs and is especially suitable for the foundation construction of urban
construction.

Rotary drill rig main performance characteristics:Strong maneuverability and quick transitions;There are
various types of drilling tools, which are lightweight and can be quickly loaded and unloaded;Adapt to a
variety of formations, and the speed is fast, about 80% faster than the impact drill;Small pollution to the
environment, no need to recycle slag.

Can correspond to various types of piles.The working principle of the auger piling machine is to use a
short auger bit or a rotary bucket to directly excavate the drilling slag such as soil or gravel with a strong
torque, and then quickly lift it out of the hole, which can realize dry construction without mud support. ,
Even in the case of special strata requiring mud wall protection, the mud only plays a supporting role,
and the mud content in drilling is quite low, which greatly reduces the pollution source, thus reduces the
construction cost, and also improves the construction environment and hole forming efficiency. high.
This is why the rotary drilling rig has good environmental protection.
