Frozen earth drill. Recommendations for drilling wells in frozen soils during engineering-geological surveys for construction. And the purpose and features of drilling engineering-geological wells in frozen soils
This auger is designed for drilling frozen or rocky soil. This auger is represented by a special drill, which can be used for drilling mainly various wells. In particular, it is possible to drill holes for pillars with a diameter of 200 mm and a depth of 800 mm. In order to achieve a significant reduction in the forces spent on drilling and at the same time speed up the work performed when drilling both frozen and directly rocky soil, it is necessary to use special removable blades that are designed specifically for this auger. At the same time, if necessary, the screw can be easily replaced. It is worth noting that this screw the best way Suitable for gas drills that have a power rating above average, as well as for high power gas drills.

With the arrival of winter, visitors to our site again have questions about drilling frozen soil because there is always a need for year-round operation of motorized drills. Frozen soil is the most difficult and unpredictable for drilling. How to choose the right motor drill for winter operation and drilling frozen soil? Even frozen sandstone, light and flowing in warm time year, in winter it can cause a lot of trouble when drilling.
The fact is that in winter the soil is bound by frozen water, which increases the density and mass of the soil, and when drilling, the water melts, and the mixture of water and soil becomes even more abrasive than dry soil. The basic principle of drilling frozen soil is that the auger drill blades do not cut frozen soil. The knives should break it into small pieces. And for this you need power and a strong transmission. The most popular mechanical motor drills for two operators - Stihl BT 360, Ground Hog C-71, Efco TR1585, Oleo-Mac MTL85, Iron Mole C-5, Hitachi da300e - definitely cannot cope with this job.
Low torque and there is a risk of transmission failure. Therefore, the only choice remains powerful ones with high torque and low revolutions of the drilling tool, for example (torque 750 Nm), (torque 1020 Nm) or Ground Hog HD 99 (torque 372 Nm). But even these heavy-duty machines cannot always cope with frozen soil, especially if it is necessary to drill holes with a diameter of more than 250 mm. Then only a drilling rig based on a tractor or other construction equipment will help you.
Drilling frozen soil requires special cutting knives which can work in an abrasive environment. Standard cutting knives Pengo 35 must be replaced with more abrasive-resistant carbide knives Pengo 1336. If pebbles or gravel are found in frozen soil, we recommend installing Pengo 5T30 knives. In order for the auger drill to start drilling, it is recommended to break open the upper layer soil, to a depth of 30 cm. The time of drilling a hole in frozen soil is tens of times higher than in ordinary soil.
When drilling, it is necessary to provide significant vertical pressure on the axis of the auger drill. At the same time, the operator must monitor the excessive load on the motor-drill transmission so that the auger does not jam in the ground and there is always a reserve in the auger rotation speed and hydraulic motor power.
When operating a motor drill in winter period, you need to remember making the right choice oils for hydraulic system And gasoline engine. Suitable for the engine is synthetic oil specification 5W30, oil specification VG32, which must be used at temperatures from - 5 degrees Celsius.
Description
The design of the BTKP series drills - a coil-free body made of high-quality steel, a powerful drill bit and reinforced cutting teeth with double fastening in a holder welded into the drill body - ensures high strength characteristics tool. Due to the use of individual geometry, the tool implements cutting and group shearing forces during the drilling process. This allows you to significantly increase drilling productivity. BTKP drills use something that has no analogues constructive solution- special removable cutting teeth original design, which allows you to secure the cutter as rigidly as possible, as an alternative to welded ones. This made it possible to significantly increase the maintainability of drills and eliminate long downtime in the event of breakage of cutters, since to restore the functionality of the drill there is no need to dismantle and welding work. Replacement of cutters is carried out in the shortest possible time in the field and does not require the involvement of specialists. But at the same time it is ensured reliable fastening cutting organs and their sufficient strength when cutting frozen and non-frozen frozen soils. The cutters are positioned in the drill body in compliance with optimal angles. A special powerful drill bit has been developed for BTKP drills, which makes it possible to effectively destroy frozen soil. The drill bit is equipped with the same cutters as the drill itself. With the same diameter, turn-free conical BTKP drill in terms of productivity and working life, it significantly (according to test results - 3-5 times) exceeds any reinforced paddle drills used in northern conditions. In addition, it reduces the load on the drilling rig, which increases its service life and saves on maintenance. Reinforced drills BTKP have long term services and are optimal for large volumes of drilling work in cases where within the framework of one project it is necessary to drill in various types soil. Drills can be used with any types of auger tools and drill rods. The tool is patented and certified.
