FRP slab band formula foundation ditch envelope

The utility model discloses a FRP slab band formula foundation ditch envelope and construction method are installed and realize excavation supporting around the foundation ditchs, include along excavation supporting location unwrapping wire, draw the hole and insert the tubular pile that adopts FRP arrangement of reinforcement material to make, three a set of constitutions of tubular pile strut the pile body, be located the tubular pile position of tubular pile top and foundation ditch cutting depth bottom department, be equipped with the hoop lock of holding the tubular pile tightly and supporting three root canal stakes respectively, strut that the winding is connected with FRP strip cloth between the front side tubular pile of pile body. The utility model discloses a FRP tubular pile through arranging the hoop lock, forms stull and restraint to strutting the pile body, and supporting construction is more stable, and FRP strip cloth plays better fender soil effect to can richen the excavation supporting type, enlarge the excavation supporting choice, shorten construction period, realize energy saving and consumption reduction, the excavation supporting form also can be followed conventional plane mode and expanded to the spatial model, has effectively improved supporting construction's rigidity, realizes the safety and stability of foundation ditch engineering.
