Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The following first describes the concepts involved in the present application in conjunction with the accompanying drawings. It should be noted that the following description of each concept is only to make the content of the present application easier to understand, and does not limit the scope of protection of the present application; at the same time, the embodiments and features in the embodiments of the present application can be combined with each other in the absence of conflict. The present application will be described in detail with reference to the accompanying drawings and in conjunction with the embodiments.

[0022] like Figure 1 - Figure 3 As shown, the utility model provides a fully assembled high-pile waterfront trestle, including prestressed concrete pipe pile columns 1, a steel structure beam 5 is arranged on the top of the prestressed concrete pipe pile column 1, the steel structure beam 5 includes at least two longitudinal beams 51 and multiple cross beams 52, all longitudinal beams 51 are arranged longitudinally, all cross beams 52 are arranged transversely, and multiple cross beams 52 and at least two longitudinal beams 51 are welded into a whole, the prestressed concrete pipe pile columns 1 are arranged in plurality, all prestressed concrete pipe pile columns 1 are symmetrically arranged in pairs at the bottom connection of the steel structure beam 5, a plurality of steel keels 6 are evenly arranged on the top of the steel structure beam 5, and all steel keels 6 are welded and fixed to the steel structure beam 5.

[0023] All the steel keels 6 are paved with trestle boards 7 , and the trestle boards 7 are prefabricated with patterned steel plates, tempered laminated glass, and anti-corrosion wood board materials, and decorative railings 8 are arranged on the trestle boards 7 .

[0024] The prestressed concrete pipe pile column 1, steel structure beam 5, steel keel 6, trestle board 7 and decorative railing 8 are all connected by welding. The connection between each component and the prestressed concrete pipe pile column 1 adopts the mode of field production and on-site assembly, which has the characteristics of factory prefabrication of all components, full assembly implementation, simple and efficient construction, etc., which greatly speeds up the construction progress, improves the construction environment and reduces the construction cost.

[0025] A steel skeleton 9 is arranged inside the prestressed concrete pipe pile column 1 , and the steel skeleton 9 includes a plurality of longitudinal bars 10 and a plurality of stirrups 11 . The plurality of stirrups 11 are evenly arranged vertically inside the prestressed concrete pipe pile column 1 , and the plurality of longitudinal bars 10 are evenly arranged horizontally between two adjacent stirrups 11 .

[0026] The plurality of longitudinal bars 10 and the two stirrups 11 are arranged in an H shape, and the two ends of the plurality of longitudinal bars 10 are connected to the two adjacent stirrups 11 by binding. By combining and binding the plurality of longitudinal bars 10 and the plurality of stirrups 11 to form a "reinforcement cage", the bearing capacity of the prestressed concrete pipe pile column 1 is improved, thereby improving the overall strength of the prestressed concrete pipe pile column 1, and also improving the stability and safety of the prestressed concrete pipe pile column 1.

[0027] The micro-expansive concrete core 3 is poured in the steel skeleton 9. The concrete can expand to a certain extent during the hydration period by relying on the action of the expansion agent, thereby compensating for the shrinkage of the concrete, achieving the purpose of preventing concrete cracks and improving concrete performance. The present invention sets the steel skeleton 9 in the flood level area at the top of the prestressed concrete pipe pile column 1, and adopts the micro-expansive concrete core 3, which can enhance the flood resistance, impact resistance and shear resistance of the pile column, strengthen the integrity of the connection between the prestressed concrete pipe pile column 1 and the steel structure beam 5, and enhance the safety and stability of the structure.

[0028] Furthermore, a connecting steel plate 4 is welded on the top of the steel skeleton 9, and a steel support plate 2 is welded on the bottom of the steel skeleton 9. The arrangement of the connecting steel plate 4 and the steel support plate 2 can prevent the steel structure beam 5 and the inner bottom wall of the prestressed concrete pipe pile column 1 from being squeezed when the micro-expansion concrete expands.

[0029] When constructing the waterfront trestle of this embodiment, firstly, all the prestressed concrete pipe piles 1 are used as high piles and columns, and are embedded in the foundation soil layer by hammering, static pressure, vibration pile sinking, etc., then, the longitudinal reinforcement 10 and the stirrups 11 are combined and tied to form a "reinforcement cage"-shaped steel skeleton 9, and then the tied steel skeleton 9 is placed inside the prestressed concrete pipe piles 1, and then the micro-expansion concrete core filling 3 is poured, and then the fixing plate and the steel structure beam 5 are erected on the top of the prestressed concrete pipe piles 1 and welded and fixed, and the trestle board 7 prefabricated with patterned steel plate, tempered laminated glass, and anti-corrosion wood board material is laid on the top of the steel keel 6, and the decorative railing 8 is arranged on the top of the trestle board 7, thereby completing the assembly project of the entire high-pile waterfront trestle.

[0030] Among them, the prestressed concrete pipe pile column 1 has the advantages of good mechanical properties, good anti-corrosion performance, high durability, high pile body quality, and high degree of standardization, and effectively solves the problems of large scouring depth of river foundation, scouring foundation, soft soil foundation, etc.

[0031] The pile top steel structure beam 5 is light and simple, has a strong bearing capacity, and is highly plastic, and can adapt to the setting of a trestle with a large span, multiple shapes, and multiple curves.

[0032] The utility model is used in waterfront projects, and can realize water operations by means of pile-driving boats, etc., and eliminate construction measures such as cofferdam operations, diversion and interception, and drainage, and has no construction pollution and is low-carbon and environmentally friendly. It also combines the advantages of concrete structure, steel structure, and prefabricated components, and uses prestressed concrete pipe piles 1 underwater and steel structure components on the water, which not only solves the problem of difficulty in underwater corrosion resistance of steel structures, but also solves the problems of heavy weight, inconvenient construction, and quality control of traditional concrete structures.

[0033] This article uses specific examples to illustrate the principles and implementation methods of this application. The description of the above embodiments is only used to help understand the method and its core ideas of this application. The above is only the preferred implementation method of this application. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of this application, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the concept and technical solution of the invention to other occasions without improvement, should be regarded as the scope of protection of this application.
