Concrete drilling technology and tool selection
When carrying out construction work, it is often necessary to encounter the need to cut a hole in concrete. This problem can be solved in several ways. You can make a hole in concrete with a conventional perforator. The method is reliable, tested in practice, but has a number of significant disadvantages that make its use narrowly focused. It is convenient to quickly destroy concrete with a perforator, it is not possible to achieve special accuracy when using it. Chips and cracks, vibrations of the entire structure, lead to the fact that the hole obtained in this way is obtained with very large gaps. Plus dust and dirt. A perforator can quickly break through the doorway under the door. In addition, the quality of ordinary crowns for drilling leaves much to be desired.
With a sufficiently deep hole, it can jam it, and the punch may deteriorate. There is also a probability of injury. Hydro -tank plunger pump with pressure of the water jet at the output of up to 1000 bar. Can cut a hole in concrete with very great accuracy, practically without destroying the main structure. The disadvantages of the method are the need for special skills and mandatory shielding of the metal plate of the zone around the cut. The next way is to use diamond coating when drilling concrete. The quality of the cut is quite high. The hole is obtained by the correct geometric shape without chips and cracks. There is an opportunity to improve the method by using a vacuum cleaner. As a rule, this nozzle is complete with equipment. For the construction of various industrial buildings, high -quality concrete is necessary.
