Description

Technical Field

[0001] This utility model relates to a hydraulic structure, specifically a seawall with an outward-cantilevered, permeable frame structure, designed to address land resource constraints and protect the marine environment in front of the seawall during current seawall upgrades and renovations. It is particularly suitable for coastal cities with scarce land resources, complex wave and hydrological conditions, and high requirements for marine ecology, possessing comprehensive functions such as disaster prevention and mitigation, ecological protection, space utilization, and land conservation. Background Technology

[0002] Seawalls are dikes built along the coast to block tides and waves, serving as crucial disaster prevention structures for protecting life and property in coastal areas. Traditional seawalls often employ a mixed earth and stone structure. Affected by tides and storm surges, seawalls are generally quite high in elevation. Considering the overall stability of the dike, they require significant land and sea area both inside and outside the dike, with a total width ranging from 50m to 200m. With the development of coastal cities, especially in economically developed areas, land resources are becoming increasingly scarce. This has led to the emergence of projects utilizing the underground space of traditional seawalls to construct warehouses, underground parking lots, and traffic tunnels. However, this method of utilizing the underground space of traditional seawall structures still presents problems such as the main dike body being located on the inland side, still occupying significant land resources, and the hardened compaction layer on the offshore side encroaching on the original tidal flats and impacting the marine ecosystem.

[0003] Therefore, this paper explores a cantilevered, open-frame seawall. The main structure of the seawall cantilevered and is suspended above the existing marine mudflats. While effectively responding to the threat of floods and tides, it can utilize the internal space of the seawall, take into account marine ecological protection and intensive and economical use of land resources, and give full play to the comprehensive functions of seawall in disaster prevention and mitigation, ecological protection, space utilization and land conservation, so as to meet the new demands for seawall construction in the new era. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing traditional seawalls in terms of underground space by providing a cantilevered, permeable frame seawall. This seawall employs a cantilevered, permeable frame structure with cast-in-place piles underneath. The main frame of the seawall extends outwards above the marine tidal flat and uses a vertical seawall structure, saving land resources compared to the width of traditional earthen inland seawalls. The frame structure utilizes the internal space of the seawall, reducing the overall load and improving its overall stability. Cast-in-place piles support the seawall, preserving the existing marine tidal flat and minimizing the impact on the marine ecosystem. Furthermore, the cantilevered pile foundations, connected to a continuous beam slab above, form an integrated structure that effectively resists wave erosion and backlash, further enhancing the safety and stability of the seawall structure.

[0005] The technical solution adopted in this utility model is as follows: An outward-cantilevered permeable frame seawall includes a permeable frame, a cast-in-place pile support structure, and a revetment structure. The permeable frame is located above the marine tidal flat. The upper parts of the cast-in-place pile support structure and the revetment structure are cast in place with the permeable frame to form an integral structure, which not only transfers the upper load to the foundation but also forms a moisture-proof and seepage-proof closed system.

[0006] The cast-in-place pile support structure serves as the foundation on the seaward side, employing a sparsely arranged cast-in-place pile layout. The revetment structure is located in the inland revetment area and includes a continuous beam at the pile top, densely arranged cast-in-place piles for the revetment, double-row densely arranged high-pressure jet grouting piles, and a road behind the dike. The double-row densely arranged high-pressure jet grouting piles are arranged inside the densely arranged cast-in-place piles for the revetment, the continuous beam at the pile top is located at the top of the densely arranged cast-in-place piles for the revetment, and the road behind the dike is located at the top of the double-row densely arranged high-pressure jet grouting piles. The continuous beam at the pile top is cast-in-place connected to the road behind the dike to form a seepage prevention curtain system.

[0007] The permeable frame is a reinforced concrete structure, including a base slab, bottom beams, continuous longitudinal beams, a tidal-facing retaining wall, inland support columns, a top slab, and a top beam. The continuous longitudinal beams are arranged above the sparse cast-in-place piles of the pile-supported structure. The base slab and bottom beams are cast-in-place connected to the right end of the continuous longitudinal beams and the left end of the pile-top continuous beams of the revetment structure. The base slab is erected above the bottom beams to form the bottom platform of the frame. The tidal-facing retaining wall is arranged above the continuous longitudinal beams, and the inland support columns are arranged above the pile-top continuous beams of the revetment structure to form the frame support system. The top slab and top beams are cast-in-place connected to the top right end of the tidal-facing retaining wall and the top of the inland support columns. The top slab is erected above the top beams to form the top platform of the frame. A wave-breaking wall is installed on the top of the tidal-facing retaining wall and is cast integrally with the tidal-facing retaining wall.

[0008] Preferably, a railing is provided on the inner side of the top of the top plate, and the railing is fixed to the top plate by bolts.

[0009] Preferably, the height of the frame space in the open frame can be controlled between 2.0m and 4.0m according to the requirements of seawall moisture prevention and human activity.

[0010] Preferably, the top inner side of the wave-breaking wall is provided with planting troughs and light troughs to enhance marine ecological protection and provide lighting function.

[0011] The beneficial effects of this utility model are: 1. Compared with traditional seawall design, this frame seawall adopts a more compact reinforced concrete structure and the main structure of the seawall is located above the marine mudflats, which basically does not occupy inland land resources.

[0012] The open frame design allows for the creation of storage spaces within the seawall, which can be used for storing disaster relief supplies, facilitating traffic, and parking vehicles, thus increasing the functionality and practicality of the seawall.

[0013] This utility model's seawall design takes into account the protection of marine ecosystems. Through its open structure, it preserves the original marine mudflats, providing a habitat for marine life and minimizing the impact on the marine environment. This not only helps protect marine ecosystems but also promotes marine biodiversity.

[0014] This utility model's seawall structure prioritizes reinforced concrete structures that are easy to construct and have minimal environmental impact, which helps reduce the overall project's carbon footprint and aligns with the principles of sustainable development.

[0015] This invention, by employing both cast-in-place pile and high-pressure jet grouting pile structures, offers significant advantages in terms of seawall construction costs and subsequent maintenance expenses. It not only ensures construction quality and efficiency but also reduces overall project costs, making this seawall an economical and efficient option. Attached Figure Description
