Construction Advantages of Rotary Drilling Rig

When a new item is born, the value it brings will conflict with the items with similar value, and the generation of this conflict will bring the comparison of advantages and disadvantages, and finally let people have choices from this comparison. In piling machinery, rotary drilling rig has been widely used in it, and its completion efficiency is beyond reproach. Compared with the traditional reverse circulation drill, the rotary drilling rig has made the following breakthroughs:

(1) Fast construction speed

Because the construction of rotary drilling rig relies on the drum drill with a valve at the bottom to break the soil and directly load it into the drill bucket to lift it to the ground, there is no need to crush the soil and return it to the hole by mud, and the average footage per minute can reach about 50cm. The construction efficiency in the suitable stratum can be increased by 5-6 times compared with drilling and punching pile machine.

(2) The construction precision is relatively high

During construction, pile depth, verticality, weight on bit, and soil capacity in drill barrel can be controlled by the fuselage computer.

(3) Low noise

The noise of rotary drilling rig construction mainly comes from the sound of the fuselage engine, and the rest of the components have almost no friction sound, which is especially suitable for use in urban or residential areas.

(4) Conducive to environmental protection

Rotary drilling rig construction mud consumption is relatively small, the main role of mud in the construction process is to increase the stability of the hole wall, and even in the soil stability of the relatively good area can use water instead of mud drilling construction, greatly reducing the discharge of mud, the impact on the surrounding environment is relatively small, while saving the cost of mud transport.

(5) Can walk by itself, easy to move the machine

As long as the bearing capacity of the site can meet the self-weight requirements of the rotary drilling rig, it can move by itself on the track without other mechanical coordination.

(6) Relatively high degree of mechanization

The construction process does not need to manually dismantle and assemble the drill pipe, no need to carry out mud cleaning treatment, etc., which can reduce the labor intensity of workers and save human resources.

(7) Under the same conditions, the bearing capacity of single pile is higher than that of bored pile

Because the rotary drilling rig cuts the soil into the hole by the simple bottom Angle edge, the hole wall is rough after the hole is formed, and there is almost no mud "daub" effect on the hole wall compared with the drilled pile, the combination degree of the pile body and the soil is relatively high, and the bearing capacity of a single pile is relatively high.

(8) A wide range of applicable strata

If the corresponding technical control is carried out in the construction process of the rotary drilling rig, due to the diversity of the rotary drilling rig configuration drill, the rotary drilling rig can be applied to various strata, and the construction process of the same pile can be completed by the rotary drilling rig, and there is no need to choose other machinery to match the hole.

(9) Easy to manage

Due to the characteristics of the rotary drilling rig itself, the machinery and personnel required in the construction process of drilling and punching piles are greatly reduced, and the electricity requirement is not high, from the management point of view, it is easy to manage and save management costs.
