[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] To facilitate understanding of this embodiment, in conjunction with Figures 1 to 6 This invention provides a detailed description of a novel vertical wave-breaking and retaining structure disclosed in the embodiments of this utility model. Example

[0026] A novel vertical wave-breaking and retaining structure includes: several vertical wave-breaking and retaining units connected in series, each vertical wave-breaking and retaining unit including pipe pile 1, reserved hole 2, steel strand 3, grouting hole 4, embedded connector 5, tenon side plate 6, mortise side plate 7, and rib plate 8.

[0027] Pipe pile 1 has several pipe sections. Each pipe section has a reserved hole 2 on its cross section. Steel strands 3 pass through the reserved hole 2 to connect the pipe sections. High-strength grout is poured into the reserved hole 2 through grouting hole 4.

[0028] The tenon side plate 6 and the mortise side plate 7 are symmetrically welded and fixed to both sides of the pipe section at the top of the pipe pile 1 through the pre-embedded connector 5. The rib plate 8 is welded and fixed to both sides of the tenon side plate 6 and the mortise side plate 7, and is welded and connected to the pre-embedded connector 5. Concrete is poured at the connection between the tenon side plate 6, the mortise side plate 7 and the rib plate 8 and the pre-embedded connector 5.

[0029] The function of the rib plate 8 is to provide support and reinforcement for the tenon side plate 6 and the mortise side plate 7; the connection between the tenon side plate 6, the mortise side plate 7 and the rib plate 8 and the pre-embedded connector 5 is filled with concrete, which further improves the corrosion resistance of the structure and extends its service life.

[0030] Preferably, the reserved holes 2 on the cross section of each pipe section are positioned corresponding to the reserved holes 2 on the cross section of the adjacent pipe section.

[0031] Preferably, the tenon side plate 6, the mortise side plate 7, and the rib plate 8 are all precast reinforced concrete structures.

[0032] Among them, the tenon side plate 6, the mortise side plate 7, and the rib plate 8 are precast reinforced concrete structures that can be produced through centralized prefabrication, which can effectively shorten the construction period and save construction costs.

[0033] Preferably, both the tenon side plate 6 and the mortise side plate 7 are right-angled trapezoidal structures. The top edges of the tenon side plate 6 and the mortise side plate 7 are the first right-angled side 91 and the second right-angled side 9, respectively. The bottom edges of the tenon side plate 6 and the mortise side plate 7 are the first inclined side 101 and the second inclined side 10, respectively. The cross-section of the upper bottom edge 111 of the first trapezoid of the tenon side plate 6 is convex, and the cross-section of the upper bottom edge 11 of the second trapezoid of the mortise side plate 7 is concave.

[0034] Preferably, the tenon side plate 6 and the mortise side plate 7 are welded to the pipe pile 1 through the lower bottom edge 121 of the first trapezoid and the lower bottom edge 12 of the second trapezoid, respectively, and concrete is poured at the connection point;

[0035] The tenon side plate 6 of each vertical breakwater retaining unit is connected to the second trapezoidal upper bottom edge 111 of the mortise side plate 7 of the adjacent vertical breakwater retaining unit by means of a tenon and mortise joint.

[0036] The use of mortise and tenon joints to connect the vertical wave-breaking and retaining units enables them to form a continuous straight-wall structure. Compared with other prefabricated structures, this reduces construction joints. Its advantages include structural stability, easy installation, and quick construction, which helps in the construction and implementation of related projects and achieves the effects of wave dissipation, wave protection, and sand retention.

[0037] In this embodiment, the pipe pile 1 adopts a segmented splicing process, that is, splicing several pipe sections into a whole pipe pile 1. During the splicing of the pipe pile 1, the pre-drilled holes 2 on each pipe section are aligned sequentially with the pre-drilled holes 2 on adjacent pipe sections according to the markings. Adhesive is applied to the cross-section of the pre-drilled holes 2 to join the cross-sections of different pipe sections. Steel strands 3 are then inserted through the pre-drilled holes 2, and primary and secondary tensioning are performed. After the secondary tensioning is completed, valves are installed at both ends of the pre-drilled holes 2, and grouting is carried out using the grouting holes 4. Once the designed strength of the cement grout reaches the standard, the splicing and fabrication of the entire pipe pile is completed. Based on this characteristic, pipe piles of different lengths can be produced according to different geological conditions and bearing capacity requirements, eliminating the need for lengthy production preparation work and significantly reducing the construction period.

[0038] Based on this, the vertical breakwater retaining unit can be prefabricated and assembled in a land-based processing plant or temporary prefabrication yard, and then transported to the construction area by transport ship after production. After being transported to the construction area, the vertical breakwater retaining unit is driven into the ground using a vibratory hammer or hydraulic impact hammer. The depth of the pile driven into the ground depends on the site geological conditions and the design bearing capacity, so that the pipe pile 1, the tenon side plate 6, and the mortise side plate 7 are all driven into the mud surface at the bottom of the water, forming a continuous vertical wall structure. Because the pipe pile 1 has high hardness, it can penetrate thick soil layers and is suitable for various geological conditions. As the main structure, it can ensure the structural stability of the breakwater and sand-blocking dike, thereby ensuring that the new vertical breakwater retaining structure provided in this embodiment has good wave-damping, sand-blocking, and soil-blocking effects.

[0039] The structure provided in this embodiment can be applied in breakwater construction or cofferdam engineering and other related fields. After the structure is constructed, the pipe pile body and the tenon and mortise side plates form a continuous straight wall structure. When applied to breakwater construction projects, it can effectively block the impact of waves and siltation, and play a good role in protecting the harbor basin, maintaining water surface stability, and ensuring the safety of ships entering and leaving the port. At the same time, the continuous straight wall structure formed by the pipe pile body and the tenon and mortise side plates can also be used as a temporary water-retaining and water-enclosing structure in the field of cofferdam engineering, so as to carry out drainage, excavation of foundation pits, or construction of buildings within the cofferdam.

[0040] The beneficial effects of this embodiment include:

[0041] This embodiment provides a novel vertical breakwater retaining structure that effectively blocks various hydraulic media such as surface waves, underwater sediment, and soil. Compared to traditional riprap embankments or cofferdams, it saves a significant amount of materials and corresponding construction machinery. Furthermore, the reinforced concrete structure offers superior construction durability and a long service life. Simultaneously, this structure can be prefabricated and assembled in onshore processing plants or temporary prefabrication yards. After production, it can be transported to the construction area by ships, reducing numerous offshore construction procedures. In subsequent breakwater wind power, cofferdam, or other project construction, it can effectively shorten the construction period and save construction costs, demonstrating promising economic benefits.
