Boring piles and a new design of pile-driving machine
- 58 Downloads
A rational technology for the boring of piles in unfrozen and seasonally frozen soils and permafrost, as well as in rock is presented. Prospects for the use of boring piles and a new design of machine are substantiated in construction. Experimental investigations of piles with multiple-turn helical blades and a machine for their boring indicated high accuracy of pile installation and machine productivity (18 piles per shift).
