First-Rate High Torque Drilling Machine All Casing Drilling Rig

The casing rotator is a kind of newly developed drilling equipment integrating the advantage of hydraulic power system and transmission device. It is controlled by mechanical, electrical and hydraulic system, featuring environmental protection and high efficiency.In recent years, our rotary drilling is widely used in subway construction, secant piling for foundation pit protection, discarded pile( underground obstacle) clearance, as well as high speed rail, road, bridge, and urban construction. In addition, our casing rotator is an ideal tool for reservoir dam reinforcement.Features are below:Foundation pile and diaphragm wall constructionA. Foundation piles for high-speed rail, bridge, road, and house construction
B. Secant piling for subway platform, underground building, diaphragm wall, and other construction requiring heavy excavation.
C. Reservoir retention wall reinforcement. 2.Cobble stone, boulders and karst cave drillingA. it supports foundation pile construction in the mountain land with cobble stone and boulder.
B. Application at coastal region is allowed, where it features thick quicksand and hole shrinkage, for foundation pile construction.
C. The piling equipment can be used for socket pile construction too.
3. Underground obstructions cleranceIn the process of urban construction and bridge reconstruction, our casing rotator can be employed for cleaning reinforced concrete pile, steel-pipe pile, steel H pile, PC pile, wooden pile, and some others, realizing foundation pile poured in place. 4.Rock stratum drilling
A. Rock socketed drilling for pile poured in place
B. Through hole drilling on sill for vertical shaft or ventilation hole
5.Deep excavationA. Poured in place for steel pipe insertion for deep foundation improvement.
B. Deep well digging for construction of reservoir and tunnelAdvantagesAside from little noise and vibration, our casing rotator has has safety.Requiring little mud, the construction site is clean. In addition to environmental protection, it prevents mud entering into concrete for high quality pile formation, which is conducive to improvement of the concrete bond stress to rebar.During construction, workers can determine the stratum and rock character, intuitively.For regular soil layer, the drilling speed of the casing rotator reaches up to 14m/hour.According to soil layer condition, the maximum drilling depth can be as high as 80m.It is easy for operator to understand the hole perpendicularity, which can be accurate to 1/500.Hole collapse can be avoided, achieving high drilling quality.Compared with other hole drilling method, our product drills holes with standard diameter and small concrete filling coefficient.Our drilling machine is distinguished by complete and speedy hole cleaning. The drilling waste at the hole bottom is no more than 3cm.
