The steel pipe pile and the ground reinforcement method of using this

摘要

Topic The steel pipe pile of the screwing in type which can raise the bearing capacity of ground securely with simple constitution and offer of the ground strengthening method which uses this. SolutionsSteel pipe pile 1, in steel shell the helical excavation wing allotted to the outer circle directly under 3 which is allotted 2 and the bottom outer circle and the top, it consists of with opposite direction helical consolidation wing to excavation wing 3 4. The reinforcement piece 5 which in the lowest section of shell 2, crosses in length direction, at the same time passes the center is allotted, furthermore with the direction which crosses in this, centering of coil component 6 is allotted. Excavation wing 3 it is the component which in lower part outer circle of shell 2 is formed helically with the metal plate, bit 3a in order to dig ground 7 is allotted on the bottom. Direction of spiral is the right screw condition. As for consolidation wing 4, in outer circle directly under the top of shell 2 with the metal plate it is constituted in excavation wing 3 and backward helical. Selective figure Figure 1
