Rotary drilling rig is a kind of construction machinery suitable for hole-forming operation in building foundation engineering. It is mainly suitable for the construction of sandy soil, cohesive soil, silt and other soil layers, and is widely used in the construction of various foundations such as cast-in-place piles, underground continuous walls and foundation reinforcement. It is a 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.

Equipment characteristics:

Rotary drilling rig This kind of drilling rig generally adopts hydraulic crawler telescopic chassis, jack-up collapsible mast, telescopic drill pipe, automatic verticality detection and adjustment, digital display of hole depth and so on. The whole machine generally adopts hydraulic pilot control and load sensing operation, which has the characteristics of light and comfortable operation. The main hoist and the auxiliary hoist can meet the needs of various situations in the construction site.

This kind of drilling rig is suitable for dry (short spiral) or wet (rotary bucket) and rock formation (core drilling rig) with different drilling tools. It can also be equipped with long spiral drilling rig, underground diaphragm wall grab bucket, vibrating pile hammer, etc. Realize various functions, mainly used in municipal construction, highway bridges, industrial and civil buildings, underground continuous walls, water conservancy, seepage control and slope protection.

Domestic experts believe that the rotary drilling rig will still have a big market in China in the next few years.
