Why Choose Rotary Drilling Rig For Low Construction?

(1) Fast construction speed.

Due to the construction of the rotary pile driver, the cylindrical drill bit with a valve at the bottom rotates and crushes the rock and soil, and directly loads it into the drilling bucket for lifting and transportation to the ground, without the need to crush the rock and soil and return it out of the hole by mud. The average footage per minute can reach about 50cm. The construction efficiency can be increased by 5-6 times compared to drilling and punching pile machines in suitable geological formations.

(2) The construction accuracy is relatively high. The construction process can be controlled by the machine computer for pile depth, verticality, drilling pressure, and soil capacity inside the drill barrel.

(3) Low noise. The noise of rotary excavator construction mainly comes from the sound of the engine on the body, and there is almost no friction sound from other components, which is particularly suitable for use in urban or residential areas.

(4) Beneficial for environmental protection. The amount of mud used in the construction of rotary pile drivers is relatively small. During the construction process, the main function of mud is to increase the stability of the hole wall. Even in areas with good soil stability, clean water can be used instead of mud for drilling construction, greatly reducing the discharge of mud and having a relatively small impact on the surrounding environment. At the same time, the cost of transporting mud outside is saved.

(5) It can walk on its own and is easy to move.

As long as the bearing capacity of the site can meet the self weight requirements of the rotary pile driver, it can move on its own by the track without the need for other mechanical cooperation.

(6) The degree of mechanization is relatively high. The construction process does not require manual dismantling and assembly of drill rods, nor does it require mud cleaning and slag treatment, which can reduce the labor intensity of workers and save human resources.

(7) No power supply is required.

At present, the small rotary drilling rigs used in the market are powered by diesel engines, which are particularly suitable for construction sites without electricity. At the same time, they also eliminate the need for cable transportation and protection, and have relatively high safety.

(8) Under the same conditions, the bearing capacity of a single pile is higher than that of a bored pile. Due to the fact that small rotary excavators rely on the bottom corner blade of the cylinder to cut soil into holes, the hole walls are relatively rough after drilling. Compared with drilled piles, the hole walls have almost no mud coating effect. After pile formation, the degree of bonding between the pile body and the soil is relatively high, and the bearing capacity of a single pile is relatively high.

(9) Widely applicable to geological formations. If corresponding technical control is carried out during the construction process of the rotary pile driver, due to the diversity of drill bits configured by the rotary pile driver, the rotary pile driver can be applied to various strata, and can be used to complete all the construction processes of the same pile without the need to use other machinery to form holes.

(10) Easy to manage. Due to the inherent characteristics of rotary pile drivers, the machinery and personnel required for drilling and punching pile construction processes have been greatly reduced compared to previous years. At the same time, the electricity requirements are not high, making it easy to manage and save management costs from a management perspective.

(11) Low price, low investment cost, fast return

Due to the emergence of small rotary drilling rig products in recent years, the purchase cost of drilling equipment in foundation construction has been greatly reduced. Equipment worth no more than one million yuan has been launched one after another, and some even invest tens of thousands of yuan to own their own construction equipment, making it easy to become a boss
