Problems solved by technology

[0004] The superstructure system of traditional high-piled wharf generally adopts a large amount of cast-in-place concrete, the amount of concrete is relatively large, and the self-weight load is relatively large, so the pile foundation structure of the lower part is not economical.
In addition, pouring of cast-in-place beams often involves lower water level formwork support and dismantling operations, the effective construction time is short, the construction period is long, and the construction efficiency is low
A large number of manual construction operations on the water, a large number of on-site workers, technicians, and management personnel, etc., it is very difficult to standardize operation management, and it is difficult to control site safety and project quality

Embodiment 1

[0057] Such as Figure 1-6 As mentioned, a modular assembly type pile foundation wharf structure system includes:

[0058] Pile foundation (1), modular superstructure (2), connection node between pile foundation and modular superstructure (3);

[0059] The overall plane size of the berths of the bulk cargo terminal is 1400 (length) * 30 (width) m, and its superstructure (2) is divided into 28 parts, which are first manufactured and processed in the factory, and then transported to the site by waterway, and then assembled and installed in place , including 14 first modular superstructure parts (2A) and 14 second modular superstructure parts (2B), each with a plane dimension of 50 (length) * 30 (width) m.

[0060] The pile foundation (1) of the modular assembly type pile foundation wharf structure system adopts straight pile steel pipe piles, which is convenient for the overall installation and construction of the superstructure part (2). In this embodiment, the first and seco...

Embodiment 2

[0069] Such as Figure 1-6 As shown, the construction method of the modularized prefabricated pile foundation wharf structure system described in embodiment 1:

[0070] a. Complete the fabrication and processing of the steel structure of the modular superstructure (2) in the prefabrication plant. At the same time, dispatch the piling ship to the project site in time to carry out pile sinking construction.

[0071] b. After the piling ship arrives at the project site, carry out pile sinking construction of the pile foundation of the wharf, and timely monitor the deviation of the pile sinking, and form the on-site pile position map of the modular superstructure part (2), and timely feed back to the modular superstructure Part (2) of the prefabrication processing department; when necessary, consideration should be given to erecting pile foundation enclosures to ensure the stability of the pile foundation deviation.

[0072] c. Complete the welding and fixing of the lower protru...

Abstract

The invention discloses a modular assembly type pile foundation wharf structure system. The system comprises pile foundations (1), modular upper structure portions (2) and pile foundation and modular upper structure portion connection joints (3). According to the technical scheme, the wharf total plane dimension: N*L(length)*B(width)m is directly divided to be the N upper structure portions (2), the N upper structure portions (2) are prefabricated and machined in a factory at first and then conveyed through a waterway to a site, and then general assembly and in-place installation are carried out. The invention discloses a construction method of the modular assembly type pile foundation wharf structure system. A large number of overwater special dangerous construction working procedures can be avoided, the number of on-site staff is reduced, the construction period is shortened, and the building efficiency is remarkably improved.

Description

technical field [0001] The invention relates to the field of ports and wharves, in particular to a modular assembly type pile foundation wharf structure system and a construction method thereof. Background technique [0002] High-piled beam-slab wharf is a type of wharf structure mainly suitable for soft soil foundations. The commonly used types of foundation piles include concrete square piles, concrete pipe piles, steel pipe piles, etc. The upper structure is a concrete beam-slab structure, and most of them are partially prefabricated structures. . In recent years, some large-scale pile-based wharves have been built on shallow covering layers or even exposed bedrock surfaces, such as Baosteel's 300,000-ton ore wharf project, Zhoushan Shulang Lake 400,000-ton ore wharf project and other large open-sea wharves The scope of application of the high-pile beam-slab pile foundation wharf structure is becoming wider and wider. [0003] In the construction of offshore ports and...
