The basic characteristics of the construction engineering multi-head drilling rig can be summarized as follows:
Versatility:
The multi-head drilling rig is an improved single-head drilling machine and is a multi-functional device.
It can adapt to various work needs by adjusting different drill bits, the number of drill bits, the layout of drill bits, etc.
High precision:
The drill bits have a higher spacing density, which can provide higher drilling accuracy according to the complexity of the project.
During the trenching process of the multi-head drilling rig, the five rotating drill bits and side cutters have no impact and vibration on the surrounding soil, ensuring the flatness and verticality of the trench wall.
High efficiency:
The multi-head drilling rig is equipped with a depth display with a depth accuracy of centimeters and accurate excavation depth.
The mud reverse circulation method is adopted, and the soil cut by the drill bit is immediately taken away by the mud, so the drilling speed is fast and the excavation efficiency is high.
Good mud control:
The multi-head drilling rig can better control the mud quality because the mud is processed in multiple stages such as sedimentation tanks, vibrating screens and cyclones, and is strictly tested and processed during the construction process.
No disturbance to surrounding foundations:
No vibration or noise during operation, and not prone to collapse, can be constructed close to the foundation of the original building or structure.
Wide range of application:
Applicable to all kinds of geological conditions such as clay, silt, sand layer, gravel layer with a particle size less than 150mm and weathered rock layer.
Economical:
Although the number of drill bits and equipment and maintenance costs of multi-head drilling rigs are higher, the overall construction cost may be lower due to higher construction efficiency.
Safety:
In the construction of urban high-rise buildings, multi-head drilling rigs can be used for underground pipeline crossing and foundation pit support projects. Its accuracy and flexibility make it an indispensable equipment in construction and improve the safety of construction.
Construction engineering multi-head drilling rig plays an important role in construction projects with its versatility, high precision, high efficiency, good mud control, no disturbance to surrounding foundations, wide range of application, economy and safety.
