Water spraying type distribution hopper device for lattice type steel plate pile cofferdam
The invention discloses a water spraying type distribution hopper device for a lattice type steel plate pile cofferdam. The water spraying type distribution hopper device for the lattice type steel plate pile cofferdam is composed of a platform, a pumping and draining system and a conical body discharging hopper. The platform comprises a floating body mechanism, a support bearing the conical body discharging hopper and a hand rail. The floating body mechanism is fixed through a rebar frame and a steel pipe frame. A formed cavity is used for fixing the conical body discharging hopper. The axis of the funnel and the axis of a water pipe spraying nozzle with the lower portion connected with a water pump water outflow pipe coincide with the vertical line of the gravity center of the platform. The pumping and draining system comprises a water pump, a water inflow/outflow pipe and a water outflow pipe spraying nozzle. Short steel pipes are evenly welded to the end round pipe wall of the water outflow pipe spraying nozzle in the direction of the outer diameter. A high-pressure water pump washes sand discharged from the conical body discharging hopper through high-speed water flow jetted through the short steel pipes of the water outflow pipe spraying nozzle, uniformly washes the materials to the periphery and redistributes the materials. Filling materials can be uniformly lifted, and deformation and instability caused by unbalance pressure generated on the periphery of a steel plate pile cell body are prevented. The silt content and the content of impurities in the washed sand are low, self compaction of the sand is facilitated after balanced filling, vibration and compaction workloads during construction are reduced, and cost is saved.
