1. What is a rotary drilling rig? What is a rotary drilling rig used for?
A rotary drilling rig is a mechanical device used for drilling soil and forming bored piles. The drill pipe drives a rotating bucket, which cuts soil and then lifts it out of the hole to remove it in a cyclical cycle. The rotary drilling rig features a multi-purpose modular design, suitable for a variety of pile construction types. It is more convenient and efficient than previous pile drivers.
Modernly, whether it's a building or a bridge, underground piles-those cement concrete columns-are constructed by first drilling a hole and then pouring concrete.#heavy equipment drilling machine#
The rotary drilling rig's accompanying drilling tools, including short spiral drill bits, standard drill buckets, and sand dredging buckets, can penetrate diverse geological formations, including clay, gravel, pebbles, and moderately weathered mudstone.
Rotary drilling rigs are widely used for bored pile construction in pile foundation projects for urban high-rise buildings, railways, highways, and bridges. They offer fast pile construction, high efficiency, and are environmentally friendly and energy-efficient. The structure of a rotary drilling rig mainly consists of two parts, chassis and working device, from the functional point of view. According to the different chassis used, it can be divided into two specifications: crawler type and automobile chassis type. The working device of a rotary drilling rig mainly includes a boom mechanism, mast, main and auxiliary winches, power head, follower frame, pressure device, drill rod, drilling tools, etc. The whole machine adopts pilot control and load sensing to maximize the convenience, sensitivity, safety and comfort of operation, and fully realize the integration of man, machine, hydraulics and electricity. 2. Advantages of rotary drilling rigs, advantages of rotary drilling rigs (1) Rapid rock entry. For hard formations, the unique construction process can achieve rapid rock entry. (2) Low construction noise, no pollution to the environment, suitable for construction areas with high environmental protection requirements. (3) Strong power. The power head acts directly on the drill bit, and the torque is kept unchanged during pile driving. (4) The rotary drilling rig is suitable for different geological conditions and has a high drilling efficiency, which is 5-6 times that of the rotary drilling rig used in this bridge. Therefore, it is suitable for engineering projects with tight construction deadlines. (5) There is no need for disassembly and assembly, and the drill rod is highly integrated into the main machine, saving working time. (6) The operation of the rotary drilling rig is controlled by a fully hydraulic system, which can ensure that all indicators such as the verticality of the pile foundation, hole position, hole depth, and sediment thickness meet the construction specifications. (7) The hole wall drilled by the rotary drilling rig has good stability, and the hole is thoroughly cleaned after drilling, which speeds up the construction progress. (8) The performance is excellent, the lifting speed is fast, and the lifting weight is large. The drilling rig can rotate 270 degrees for construction, and the workbench can be moved forward and backward, which can drive both small and large pile diameters.#heavy equipment drilling machine#
