Description

Technical Field

[0001] The utility model relates to the technical field of port engineering, and more specifically to a high-pile dock steel structure. Background Art

[0002] A piled wharf is a common port facility, mainly used for loading and unloading cargo and for passengers embarking and disembarking. It consists of a series of decks supported by high piles, which are usually reinforced concrete columns that penetrate into the seabed or riverbed to provide stable support. The design of the piled wharf allows ships to dock safely at different water levels and can adapt to large tidal changes. The piled wharf is mainly composed of pile foundation and superstructure, among which the pile foundation technology has developed rapidly, and the design and construction technology of reinforced concrete piles, prestressed reinforced concrete piles, prestressed large pipe piles, steel pipe piles, etc. has become increasingly mature, adapting to different geological conditions and conditions of use. Different pile types can meet the use requirements; however, the superstructure technology of the piled wharf has developed slowly, and there are fewer structural forms to choose from. So far, beam-slab structures are basically used.

[0003] The high-pile beam-slab wharf is a type of wharf structure that is mainly suitable for soft soil foundations. Common pile forms include concrete square piles, concrete pipe piles, steel pipe piles, etc., and the upper structure is a concrete beam-slab structure. At present, the upper structure system of traditional high-pile wharves generally uses a large amount of cast-in-place concrete. The casting of cast-in-place pile caps or beams often involves the support and removal of formwork at a lower water level. The construction window is short, the construction period is long, and the construction efficiency is low. In addition, a large amount of concrete construction work on the water will cause serious environmental pollution such as noise and dust during the on-site construction process. It is very difficult to standardize the operation management, and it is difficult to control the on-site safety and project quality.

[0004] Therefore, how to provide a high-pile wharf steel structure that is efficient and fast to construct, has low construction difficulty, and is easy to manage is a problem that technical personnel in this field urgently need to solve. Utility Model Content
