Wharf upgrading and reconstruction structure and wharf upgrading and reconstruction construction method

Abstract

The invention provides a wharf upgrading and reconstruction structure and a wharf upgrading and reconstruction construction method. The wharf upgrading and reconstruction structure comprises a newly-built wharf arranged on the side, facing a water area, of an old wharf; multiple foundation piles are arranged at the bottom of the newly-built wharf; a space is reserved between the old wharf and thenewly-built wharf; multiple transition plates are arranged in the space; one ends of the transition plates are arranged on the old wharf, the other ends of the transition plates are arranged on the newly-built wharf; buffer plates are arranged between the rear side faces of the transition plates and the old wharf; buffer plates are arranged between the front side faces of the transition plates andthe newly-built wharf; and buffer pads are arranged between the lower side faces of the transition plates and the old wharf and between the lower side faces of the transition plates and the newly-built wharf. According to the wharf upgrading and reconstruction structure and the wharf upgrading and reconstruction construction method, the construction efficiency of upgrading and reconstruction of the old wharf is enhanced, the construction period is shortened, the construction cost is reduced, and the operation interruption time caused by upgrading and reconstruction of the old wharf is shortened.

Problems solved by technology

[0002] Some old gravity wharves that have been in operation for decades, because of the design standards and berthing capacity requirements of the year, can no longer meet the needs of modern operations, especially decades of wind, waves, currents, berthing forces, and ship tie forces. Under the action, the pile foundation and the upper structural parts have concrete damage, protective layer falling off, and steel bars exposed. The upgrading and reconstruction of the old gravity wharf is the requirement of the times.

[0003] The traditional gravity old wharf includes the old wharf formed by stacking gravity blocks and the riprap prism under the old wharf, and the method of transforming the traditional gravity old wharf: most of them use hook machines, hydraulic breakers, automatic Machines such as unloading trucks break up, dismantle, and transport away all the gravity block structures of the old wharf, and then rebuild the old wharf at the original site. Due to the high hardness of the gravity block, the large number of layers, and the large number, a large number of different types are required. Only mechanical equipment and manpower can break and transport the blocks away. The construction period is long, and the instability of the gravity wharf block itself also brings a greater construction safety risk to the demolition work. Usually, most of the gravity wharf blocks have thickness below them. Larger riprap prisms are not easy to clean and have a great impact on the construction of new wharfs, often causing foundation piles to fail to penetrate the remaining riprap prisms under the original old wharf, resulting in pile foundation cracks and broken quality ACCIDENT

However, the period and funds required for new wharves are greater, resulting in a longer operating time for the interruption of the upgrading and transformation of gravity-type old wharves
