PURPOSE:To eliminate the need for the foundation of climbing crane by a method in which a floor plate for foundation, having a desired surface area, is attached to the lower part of the base frame of the climbing crane through a vertical force component transmitter and then contacted with the base ground. CONSTITUTION:A leveled ground 2 is formed on sloped ground in a mountaneous region, and a hole 7 of a given dimension is excavated. Then, the foundation slab 15 of a climbing crane for constructing a power transmission steel tower is set on the leveled ground 2. Also, a support leg 13 is attached to a bracket 12 and inserted into the hole 7, the vertical force component transmitter 19 of the base frame 11 is matched with a receiving base 18, the level is adjusted by a regulator 20, the hole 7 is embedded with excavated soil, and then the support leg 13 is fixed. Furthermore, a guide rope is laid between the gusset plate of the steel pole 8 of the foundation of the steel tower and the plate 10 of a guide mast 4. In this way, the vertical force component of loads is transmitted through the foundation slab 15 to the ground, and the setting of the foundation is made easier as the ground contact area increases. |
