Row of inclined holes passing through foundation of structure is drilled from its inner side, vertical holes are drilled from outer side of structure around its perimeter and vertical holes arranged in rows over area of structure basement are also drilled. Three vertical holes arranged over area of basement are drilled and filled with grouting by pouring it into hole which is adjoining two other drilled-out holes. Grouting is poured till it flows out of their mouths. EFFECT: enhanced reliability of fixing and hydraulic insulation of foundation mass and ground in footing of existing construction structures. 2 cl |
