Description

Technical Field

[0001] The present invention relates to the technical field of port engineering, and in particular to an overall modular prefabricated assembled high-pile wharf structure and an assembly method thereof. Background Art

[0002] The high-pile wharf structure is the main type of wharf structure in port projects. It transfers the upper load to the deep foundation by sinking the piles into the solid bearing layer, and is particularly suitable for geological conditions with deep and soft soil layers. Conventional high-pile wharves use a large number of cast-in-place concrete structures. During the construction process, there are a lot of on-site formwork support, steel bar binding, concrete pouring and other work. The marine environment conditions faced by port projects are complex and harsh. A large amount of on-site concrete pouring work has greatly increased the construction difficulty of high-pile wharves, resulting in slow construction speed and difficult to control construction quality. Especially in the face of extreme sea conditions during the construction period, it is very easy to cause disasters.

[0003] In recent years, port engineering builders have proposed the concept of prefabricated high-pile wharfs. By rationally splitting the superstructure of the high-pile wharf to form standardized components, the standardized components are then assembled on site through node connections to form a whole. Through standardized component design, mechanized installation, information management and other means, the workload of on-site operations has been effectively reduced, and certain results have been achieved.

[0004] Chinese utility model patent CN113481931A (publication date: October 8, 2021) discloses a modular assembled high-pile wharf structure and its construction method. The invention prefabricates modular pile foundations, modular π-shaped plates, modular beams and modular steel structure pile cores, and performs modular assembly to form a high-pile wharf, thereby improving the degree of assembly of on-site construction.

[0005] Chinese utility model patent CN115928653A (publication date: April 7, 2023) discloses a modular assembled high-pile wharf structure, construction method and monitoring system. The high-pile wharf structure of the invention is convenient and fast to construct, shortening the construction period. The pile foundation adopts a combination of straight piles and inclined piles. The straight piles bear the vertical load of the wharf structure, and the inclined piles bear the horizontal load of the wharf, making the wharf structure more stable. Sensors are installed in each component to collect and monitor the quality parameters of each component during use to ensure the safe use of the wharf.

[0006] Although the above-mentioned prior art reduces the workload of on-site operations to a certain extent, it does not completely solve the problems of too many connection nodes, dense steel bars and small space at the nodes, difficult node construction, difficult node quality control, and low assembly rate. Based on this, the present invention provides an overall modular prefabricated assembled high-pile wharf structure and assembly method, which reduces the node connections of the assembled high-pile wharf by prefabricating the components of the wharf superstructure in an integrated manner, and fully utilizes the capacity of large-scale ship machinery equipment to overcome the shortcomings of the prior art.

Taking a typical 7-span wharf structure section as an example, the assembled high-pile wharf structure currently provided by CN113481931A requires 8 prefabricated cross beams and 28 prefabricated π-shaped plates, with a total installation quantity of 36 pieces.
