PURPOSE:To form the pole foundation having great resitance to lateral pressures by a method in which a connecting annular part is driven into the ground through a pole whose lower part is fixed to a pit, and a resistance plate is driven into the ground while guiding the connecting part of the connecting annular material. CONSTITUTION:A pole 10 is inserted into a pit 11, and a liquid cement 12 is injected while confirming the verticality of the pole 10 and hardened. A connecting annular part B (as shown by the oblique line) is brought down to the ground's surface to be excavated and then driven into the ground until its upside is leveled with the ground's surface. Under the condition that a sleeve 2 is fitted into the space formed by the combining plate 7 and the guide plate 6 of the connecting annular part B, the resistance plate A is likewise driven into the ground and connected to the annular part B by a bolt 8, and the space of the excavated ground and the pit 11 is embedded with soil to complete the formation work of the pole foundation. The resistance plate A thus resist the lateral pressure to the pole 10, ensuring the self-supporting property of the pole 10. |
