GEOTHYNTHETICS TUBE CONSTRUCTURE ADOPTING FRICTION-BUMPER PART FOR CIVIL ENGINEERING WORK AND NEEDLE DEVICE FOR THE SAME

摘要

The present invention is to provide a tube structure capable of being easily assembled and having improved strength. To achieve the same, the present invention includes multiple unit tube units formed in a horizontal direction, which is a longitudinal direction, having a portion overlapped with a portion of an adjacent unit tube unit, and joined by at least one layered joining thread in a horizontal direction of the overlapped portion. The joining thread formed in the horizontal direction of the unit tube unit forms a joining thread joining unit at a first preset width from an adjoining thread in a vertical direction and at a second preset width from both ends of the joining thread. At least two joining thread joining units are formed on the overlapped portion of the unit tube units. A friction and shock-absorbing unit is formed at a third preset width from both joining thread joining units and generates frictional resistance while the unit tube units face each other. A reinforcing unit in face-contact with the multiple unit tube units is formed across the multiple unit tube units in a vertical direction. A sub friction unit at a fourth preset width in a horizontal direction of the reinforcing unit in face-contact with the unit tube units to resist against a tensile force applied to a vertical direction by using the friction force of the portion of the unit tube unit in face-contact with the reinforcing unit. The joining thread joining units are formed in both sides of the sub friction unit.
