Nowadays, when carrying out large-scale construction works, as a rule, a considerable number of units of powerful and bulky equipment are used. For example, an excavator will quickly and efficiently dig a large pit, and with a bulldozer, you can easily level a construction site of any size. However, such huge machines cannot penetrate the narrow passages between the houses and dig a small hole there. In general, the capabilities of powerful modern building mechanisms differ in some functional limitations.
In such cases, small-scale mechanization tools come to the rescue, which include a motor-drill for excavation, which allows you to dig a hole of the required depth and diameter in almost any type of soil. Moreover, this compact unit is able to work in conditions of even the most limited space. Motobur for earthworks has not only small dimensions, but also relatively light weight, which allows one person to control it.
This installation is an extremely versatile technical tool that allows you to perform not only earthmoving in various types of soil, but also drill, for example, a hole in the ice. Such a unit can easily cope even with the drilling of a full-fledged well. The use of this means of small-scale mechanization makes it possible to quickly, efficiently, efficiently and without significant effort cope with any planned task.
Motor drills for land have fundamentally changed the technology of excavation. Bursting rapidly into the market for construction equipment, they literally transformed the idea of builders about the boundaries of the capabilities of small-scale mechanization. Motobau for earthworks not only very quickly became super popular, but in many situations it is simply irreplaceable. Especially considering modern total urbanization and extremely high building density. Where bulky construction equipment will not pass, a motor-drill for earthworks will make it easy to carry out the necessary operations with the most minimal efforts and time costs. Often there are situations when he simply does not have an alternative.
Today, on the market of construction equipment, there are a huge number of models of motor-drilling installations, but almost all have the same operating principle. A screw-type drill nozzle is mounted on a two-stroke gasoline engine . As fuel, gasoline grades A-92 and A-95 are used. Waste soil during drilling is automatically extracted. Almost all models are now equipped with a special safety system that blocks the engine in case of emergency (loss of control, jamming of the working part in the soil, etc.). In addition, it serves to prevent accidental starting of the motor. Significantly expands the functionality of the motor-drilling unit with a set of interchangeable screws (nozzles) of various diameters.
Modern models are equipped with quick-detachable joints of a special design, which allow changing nozzles immediately and without significant effort. The drilling depth is increased by attaching additional rods to the main screw part. To quickly remove the drill, many units are equipped with reverse gear. Uninterrupted operation and long-term operation of the unit will be ensured only by the use of lubricants and fuel substances recommended by the manufacturer.
Among the main areas in which the drill is actively used for earthworks today, the following stand out: installation of piles, supports and poles for various purposes, erection of fences and various enclosing structures, digging trenches for laying gas pipelines, cables and other things, dismantling, sampling of soil.
