Preferably, the method comprises the following steps: the horizontal sides of the upper tripod and the lower tripod are connected, the connection part is parallel and level with the upper surface of the back cover concrete, the bottom end of the vertical side of the lower tripod is contacted with the bed course of the rubble, namely, the height of the vertical side of the lower tripod is equal to the thickness of the back cover concrete.
The utility model has the advantages that:
1. the utility model discloses a steel sheet pile cofferdam and back cover concrete connection device all adopt bolted connection, simple structure, be convenient for installation and dismantlement.
2. The utility model discloses an anti tripod that misplaces about superficial steel sheet adopts bolted connection, makes steel sheet pile embedding back cover concrete can one-way displacement, not only helps steel sheet pile cofferdam to provide anti buoyancy at the concrete back cover, does not influence engineering later stage steel sheet pile pull out work moreover.
3. The utility model discloses a steel sheet pile cofferdam and back cover concrete connection structure, can strengthen the cohesive force of back cover concrete and steel sheet pile, improve the anti ability of floating of back cover concrete greatly, reduce concrete placement thickness, safety and stability, economic environmental protection.
