Small rotary drilling rigs are the main force in the development of rural construction, which solves the problems of piling in rural housing construction, such as a lot of backfill and the stability of the foundation. Although large rotary drilling rigs have high efficiency, they are large in size, high in investment costs, and difficult to disassemble and assemble. It is inconvenient to transport and only suitable for large construction sites.
The following are the advantages of small rotary drilling rigs:
●Fast construction speed
Rotary drilling rig construction is to rely on the bottom with a valve of the drum drill rotary crushing rock and soil, and directly into the drill hopper lifting to the ground, without the rock and soil crushing mud back out of the hole, the average footage per minute can reach about 50cm. Construction efficiency in suitable stratum can be increased 5-6 times compared with drilling and punching pile machine.
●High construction accuracy
During the construction process, the pile depth, perpendicularity, drilling weight and soil capacity in drill barrel can be controlled by computer.
●Low noise
Rotary drilling rig construction noise mainly from the engine, the rest of the parts almost no friction sound, which is very suitable for urban or residential use.
●Conducive to environmental protection
The amount of construction mud used by rotary drilling rig is relatively small. The main function of mud during construction is to increase the stability of hole wall. Even in areas with good soil stability, clean water can be used to replace mud for drilling construction, which greatly reduces the discharge of mud, has little impact on the surrounding environment, and saves the cost of outward transportation of mud.
●It can walk by itself and move easily
As long as the site bearing capacity can meet the rotary drilling rig weight requirements, it can move on its own by the crawler without other mechanical assistance.
●High mechanization
The construction process does not require manual disassembly and assembly of drill pipes, and no need to remove mud, thus reducing intensity of workers
●No power supply requirement
The small rotary drilling rigs used in the market today are powered by diesel engines, which are especially suitable for the construction site without electricity，and also saves the hauling, laying and protection of cables, and the safety is relatively high.
●The bearing capacity of single pile is higher than that of bored pile
Since the small rotary drilling rig cuts the soil by the bottom corner edge of the cylinder, the hole wall is relatively rough after the hole is formed, and the hole wall has almost no smearing effect of mud compared with the bored pile. , the bearing capacity of the single pile is relatively high.
●Applicable to a wide range of strata
If the corresponding technical control is carried out in the construction process of rotary drilling rig, due to the diversity of rotary digging pile machine configuration drill, rotary drilling rig can be applied to all kinds of stratum, in the same pile construction process can be completed by rotary drilling rig, without the need for other mechanical cooperation
●Easy to manage
Due to the characteristics of rotary drilling rig, compared with the drilling and punching pile construction process required machinery and personnel are greatly reduced, while the electricity demand is not high, easy to manage and save management costs.
