The construction and repair works and core drilling were implemented for the need of the produce in this mill in General Toshevo. Different diameter vertical openings have to be made in a concrete plate. The diameter range includes: 122, 152, 162, 182, 202, 250, 302, 402 and 500 mm. Also, square openings (400/400 mm and 1500/1500 mm) and complex holes of 900 mm diameter are done.
The works continue with the last opening of 900 mm diameter. The drill stand is fixed and working. We have also done the square openings.
The core drilling in the floor begins. The reinforced concrete of the openings is being pulled out with anchors placed there in advance. The diamond coring machine has tools with different diameter which are fitted according to the needs of the usage.
First, the places of the openings are being marked. The workers will then fix the drill stand for every hole they make.
