Background

After the large steel or concrete structural member is transported to the wharf by a ship, the cargo is usually directly unloaded to the wharf by a heavy crane, a floating crane or a crawler crane according to the conventional method. Because steel or concrete structural members usually weigh more than hundreds of tons and even up to thousands of tons, and the lifting capacity of the related crane is limited, under special conditions, a crane unloading method is abandoned by a construction unit, and an SPMT modularized vehicle is directly used for boarding and directly unloading after jacking.

Because the unloading of the SPMT modular vehicle requires high dock load capacity and requires a dock-mean load. The method is generally implemented for mature commercial docks and heavy duty docks. However, if the receiving dock is a non-finished and non-heavy-duty dock, due to factors such as process and cost, the SPMT modularized vehicle has to be used for unloading, and the cantilever in front of the dock wall cannot bear load, how to avoid damaging the front suspension structure of the dock wall and adjust the height of the dock, and how to enable the SPMT modularized vehicle to smoothly drive in and out the cargo ship are critical problems.

In one embodiment of the utility model, the auxiliary soil table structure is constructed by 20-30 cm of gravels as basic materials on the concrete surface of the wharf wall top according to the on-site elevation difference through the technical means of water generation, backfilling, rolling and the like. After the whole auxiliary soil table 2 is rolled, the bearing capacity of the auxiliary soil table is ensured to be more than 10T/m. Avoiding the region of the wharf cantilever 1 and the convex edge region, and calculating the size of the auxiliary soil table 2 according to the SPMT loading condition. The length of the springboard section is 6.5m, the width is 1m, the height is 0.2m, the material is AH36 marine steel, and the yield strength is 355Mpa, and the springboard is of a welded steel structure. After welding, all weld joints UT are subjected to flaw detection, and the weld joints UT reach more than two stages. The first gussets 44 have a plurality of rib plates 45 added at 1m intervals therebetween to improve bending strength. The bottom of the first bottom plate 41 needs to be welded with a limiting block to prevent the springboard from moving along with the ship body, surge and other reasons, so that the springboard slides and falls off. On the dockside, directly onto the laid steel pad 3. And then paving the springboard transition sections 6 on two sides of the springboard section 4. The ramp length of the springboard transition segment 6 is 2m, the width is 1m, and the gradient is 5 degrees.
