EXECUTION CONSTRUCTION OF LANDSLID PROTECTION PILE AND EXECUTION METHOD

PURPOSE:To enhance rigidity by forming a plurality of vertical piles driven into the ground, a slope coupling pile coupling the lower end of one vertical pile with the upper end of the other vertical pile and a horizontal coupling pile coupling the vertical piles in the horizontal direction. CONSTITUTION:Excavated vertical piles 2 and 2 are buried into two adjacent vertical holes 21. After that, one end of a wire 14 as the core of a horizontal coupling pile 4 is connected to the rear of an excavator from a coupling hole 13 of one pile 2 to excavate a horizontal hole 16, the excavator is withdrawn from the other pile 2, a stopper 15 is fixed to one end of the wire 14 to strain the tension piles 2 and 2 from the other end, and a sticking agent 17 is poured to the inside of the pile 2 until the hole 16 is buried. Then, an outside pipe welding a drilling bit 26 to the front end thereof is made as a slope coupling pile 3 toward the bottom of the other pile 2 from a neighborhood of an opening of a hole 21, an inclined hole 22 is excavated by an excavation rod using a hole widening bit 26 on the front end thereof as an inside pipe to bury the pile 3, the pile 2 is drilled with the bit 26 to insert the front end of the pile 3 into a drifting 8, and a sticking agent 9 is filled from the top of the pile 3 to connect the piles 2 and 3.
