The main reason is the commercial attractiveness of the acquisition of buildings in the central part of the city and the addition of additional floors. As a result, the load on the foundation increases. Another task that requires strengthening the foundations is the settlement of buildings and, as a consequence, the appearance of cracks on the walls. Similar problems arise due to improper use of buildings and soil soaking at the base of foundations, or due to mistakes made in design or construction. If the reconstruction of the building takes place without increasing the loads on the foundations, then usually in this case, the cementation of the soils at the base of the foundations is performed , as well as the strengthening of the foundation masonry. In the event of an increase in the loads from the building, the reinforcement of the foundations is carried out with the device of bored injection piles. The same method is used to strengthen the foundations of buildings during construction near a new building with the development of a foundation pit. Strengthening the foundations of buildings on the street. Viktorenko, Moscow Bored piles (micro piles) are drill piles with a diameter of up to 300 mm and can be performed using different technologies. CFA piling K include, for example, piles samozaburivaemye Titan or Atlas ® . The essence of the Titan pile technology is to combine drilling and cementation operations. In this case, special hollow drill rods are used, which, after the completion of drilling, remain in the body of the pile as a reinforcing element. Titan piles diameter is 150- 250 mm... When piles of higher bearing capacity are required, MiniJet ® drill piles are used . Unlike Titan piles, when installing MiniJet ® piles , an increased pressure of a jet of cement mortar of 150-200 atm is used. The MiniJet pile diameter is 250-400 mm...
