Combined type ship lock structure

A combined type ship lock structure comprises an integrated structure, connecting pieces and sheet piles. The integrated structure is composed of a lock wall and a flat-bottom-shaped bottom plate. The elevation of the top of each sheet pile is between the original ground elevation and the elevation of the top of the lock wall, the elevation of the bottom of each sheet pile is smaller than or equal to the elevation of a foundation surface, and the elevation of the top face of backfill is smaller than or equal to the elevation of the top of the lock wall. During excavation, lateral bracings are adopted, and a built ship lock is very close to the combined type ship lock. Before construction, the sheet piles, the lateral bracings and the connecting pieces are prefabricated. The connecting pieces are fixed to the sheet piles to connect the sheet piles with the integrated structure, then, the bottom plate is constructed, and finally, the lock wall is constructed. By means of the combined type ship lock structure, the amount of reinforced concrete can be reduced, the stress of the integrated structure can also be improved so that the combined type ship lock structure can meet the requirement of higher filling behind a wall better, the excavated volume of earthwork can also be reduced, and a series of problems caused by stacking of abandoned soil can be avoided. The combined type ship lock structure can expand new study fields for design and type selection of building near ship lock structures.
