For fixing the walls of pits of the underground parts of tall buildings can be used sheet pile walls, the walls of discretely arranged pile of supports to zabirkoy ‘wall in the ground’, the wall of , secant and screw piles and other methods of design and construction of fences, ensuring the stability of the sides of pits being built facilities, selected according to their depth and dimensions, physical and mechanical characteristics of soil, amount and nature of the load on the curb, technological equipment and economic indicators. 4.17. When using bored piles as foundation pillars of high-rise buildings should pay particular attention to ensuring high-quality stripper bottom of the borehole before it is concreting and reliable bearing piles to the current carrying layer of soil. In the case of sinking wells in the unstable soil beneath the mud should include activities (eg, special bookmark intravenous tubes) for additional grouting piles heels to ensure the quality of contact with the ground plate. 4.18.

When the device of multi-storey underground facilities for high-rise complexes should consider their construction method ‘top down’. In this case, the passage of soil for the next device underground floor is the small-sized earth-moving equipment from the previous ceiling. Exterior walls of the underground floors performed in a ‘wall in the ground’ and are simultaneously guard unearth the pit, and spacer fence system is included in the design of the overlap between the underground floors. Issuance of the developed soil at surface through openings left in the overlap. Production work on the method of ‘top down’ only permitted subject to agreement of technical documentation, in particular referred to the technological Regulations (Section 4.10), with the organization, which is the author of the project works of the zero cycle, and the positive resolution of geotechnical expertise. 4.19. When carrying out the zero cycle of tall objects to be waged the following technical documentation: general journal papers in the form prescribed snip 1.12; special journals for certain types of work (eg, piling, compacting foundation soil, etc
