Description

Technical Field

[0001] The present invention relates to the technical field of seawall ecological structures, and in particular to a seawall ecological modular system. Background Art

[0002] Seawalls serve as a safety barrier against wind and waves in coastal areas, effectively preventing storm surges and resisting the invasion and scouring of the coast by waves and currents. To effectively resist wave attacks, traditional seawalls basically adopt hard slope and bottom protection structures, resulting in a monotonous facade structure and simple design. Most of them are made of single stones, causing the outer mudflats of the seawall to shrink and the coastal mudflat habitats to be damaged, thus destroying the marine ecological environment.

[0003] Moreover, the ecological transformation of seawalls faces problems: the wave energy near the coast is large, the average wave height is large, the tide speed is fast, plants are easily fallen over, the dry season is long, and the sea vegetation is submerged for a long time, resulting in a low plant survival rate; and the construction conditions of the ecological transformation project of the seawall are limited. For example, the landscaping inside the embankment has been completed, resulting in limited space and the embankment cannot bear heavy machinery; irregular semi-diurnal tides require sea operations, and the construction cost outside the embankment is high and the construction is difficult.

DETAILED DESCRIPTION

[0040] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0041] like Figures 1 to 3 As shown, the seawall ecological modular system provided by the embodiment of the present application includes a slope protection belt 100 and a pipe pile belt 200. The pipe pile belt 200 is located on the side of the slope protection belt 100 away from the sea water, and a wave-breaking wall 300 is provided on the upper end of the pipe pile belt 200.

[0042] Also included: a plurality of ecological vegetation module structures 400;

[0043] A base layer 500 is provided on the slope protection belt 100 near the pipe pile belt 200. The base layer 500 is made of concrete. A gravel buffer zone 600 is provided on the side of the base layer 500 close to the seawater.

[0044] Multiple ecological vegetation module structures 400 are arranged in sequence according to a preset height and arranged on the foundation layer 500; multiple ecological vegetation module structures 400 form a first step, a second step, and a third step from the slope protection belt 100 to the pipe pile belt 200:

[0045] Among them, the planting height of the first tier is from the average low tide level to the average sea level, the planting height of the second tier is the average sea level, and the planting height of the third tier is from the average sea level to the average high tide level.

[0046] In this embodiment, the ecological vegetation module structure 400 includes: a mesh cage structure 410, a pebble layer 420, a support layer 430, a purification layer 440, a nutrient layer 450, a soil consolidation layer 460 and a planting layer 470;

[0047] The cage structure 410 is a rectangular cage structure, and the pebble layer 420 is arranged at the bottom and around the cage structure 410. A filling space is formed inside the pebble layer 420. The support layer 430, purification layer 440, nutrient layer 450, soil consolidation layer 460 and planting layer 470 are arranged in sequence from bottom to top in the filling space.

[0048] Among them, the pebble layer 420 can reduce the impact of waves and play a water-permeable role. The supporting structure can provide supporting strength for the modular structure under the impact of waves and increase the overall stability. The purification layer 440 provides a carrier for microorganisms to attach and can purify seawater at the same time. The nutrient layer 450 can provide rooting and growth for newly planted aquatic plants, provide nutrition for the root system, and promote rooting and germination. The soil-fixing layer 460 plays a role in preventing over-wave erosion of the nutrient layer 450. The planting layer 470 is for planting different aquatic plants, which effectively improves the diversity of the seawall's ecological landscape.

[0049] As a preferred embodiment, the cage structure 410 is composed of gabion mesh, which has a strong ability to resist natural damage and corrosion. Combined with the internal pebble layer 420 and the support layer 430, it can withstand a large range of deformation without collapsing.

[0050] To construct the 410 cage structure, select a flat, hard surface. Unpack the bundled gabion mesh and remove a complete gabion unit. Erect the partitions and front and rear panels. Secure the corners with extended edge wire, ensuring the upper edge of the gabion is level and all vertical partitions and panels are perpendicular to the base. Finally, use long steel wire to twist all adjacent vertical edges, forming a double-single-double-twist pattern at intervals of 10-15 cm. The assembled gabion mesh must be placed on a flat surface to prevent deformation. Use specialized lifting equipment for installation, with lifting points spaced 1 meter apart. Do not use a single-hook crane for lifting. Use a rigid hanger for all lifting operations. During lifting, the lifting rope must be perpendicular to the gabion mesh. Lifting is accomplished using both mechanical and manual methods.

[0051] As a preferred embodiment, the pebble layer 420 is formed by stacking a number of pebbles. The stacking height of the pebble layer 420 is the same as the height of the mesh cage structure 410. The pebbles are gray pebbles with a diameter of 80-120 mm to block the grid spacing in the mesh cage structure 410. At the same time, the pebble layer 420 can buffer the impact of waves, reduce water dynamics, and at the same time, the gaps between the pebbles act as water permeability.

[0052] As a preferred embodiment, the support layer 430 includes: wooden piles, wooden frames and X-shaped wood. The wooden piles are located at the bottom of the pebble layer 420. There are 6 wooden piles, which are arranged in a crisscross pattern. The wooden frame is located on the outside of the wooden piles. The wooden frame is fixed to the wooden piles by X-shaped wood, providing a stable structure in the offshore environment where waves frequently impact, while ensuring its permeability.

[0053] As a preferred embodiment, the purification layer 440 includes a thick impact-resistant coconut fiber mat, which is bound to the mesh cage structure 410 by steel wire. The purification layer 440 serves to provide an attachment carrier for microorganisms and purify seawater.

[0054] As a preferred embodiment, the nutrient layer 450 uses planting soil mixed with fertilizer, and the fertilizer can be nitrogen fertilizer.

[0055] As a preferred embodiment, the soil-solidifying layer 460 includes: a first branch layer 461, a gravel layer 462 and a second branch layer 463. The first branch layer 461 is arranged above the nutrient layer 450, a gravel layer 462 is laid above the first branch layer 461, and a second branch layer 463 is laid above the gravel layer 462. In addition, the first branch layer 461 and the second branch layer 463 are respectively connected to the mesh cage structure 410 by steel wire.

[0056] Specifically, the first branch layer 461 uses several dead branches with a diameter of 100mm and a height of 200mm, with a horizontal and vertical spacing of 300mm, and is fixed with pebbles or a mesh cage structure 410 using a 3mm diameter steel wire; the gravel layer 462 uses gravel with a diameter of 50-80mm and a thickness of 100mm; the second branch layer 463 uses several branches with a diameter of 15mm and a 3mm diameter steel wire for binding on the outside, and the horizontal and vertical spacing of the branches are both 150mm, so that the first branch layer 461, the gravel layer 462 and the second branch layer 463 form a soil solid layer 460 to prevent over-wave erosion of the planting soil.

[0057] As a preferred embodiment, the first level, the second level, and the third level each include an ecological vegetation module structure 400;

[0058] The planting layer 470 in the first-tier ecological vegetation module structure 400 adopts the first type of aquatic plants, which include: Tung trees, Acanthus species and other mangrove plants;

[0059] The planting layer 470 in the second-tier ecological vegetation module structure 400 adopts the second type of aquatic plants, which include: any one or more of broad-breasted chrysanthemum, bitterling tree, and halo fern mangrove plants.

[0060] The planting layer 470 in the third-tier ecological vegetation module structure 400 adopts the third type of aquatic plants, which include: any one or more of the wetland herbaceous plants such as reed, short-leaved gentian, salt-loving iris, cattail and pickerel grass.

[0061] The plants used in the ecological vegetation module structure 400 were selected based on the site's salt and flood tolerance requirements. The overall plant landscape is dominated by salt-tolerant plants, with mangroves interspersed in some areas. Low-growing plants were chosen to create a distinct landscape effect without obstructing views, creating an ecological, natural, and diverse plant community.

[0062] The total length of the above three ecological vegetation module structures is 400, which can be flexibly combined within the range of 4.0-20.0 meters according to the landscape design to form a staggered landscape outside the embankment.

[0063] The aforementioned ecological vegetation module structure 400 is implemented by hoisting three modules outside the dike, creating a stepped layer without breaching the sea use redline. Different halophytes are added according to tidal levels, creating a staggered and dynamic plant layer. This reduces the vertical height difference of the dike. Rockfill is used in front to reduce water dynamics, increase biodiversity, and enhance the quality of the ecological landscape. This construction technology offers numerous advantages: reduced offshore work, improved construction efficiency, and lower costs; a small storage yard that does not impact the landscape greening area; a lightweight modular design that eliminates the need for heavy machinery; a small construction area that does not affect tourists; and rapid landscape completion with low maintenance.

[0064] As a preferred embodiment, guardrails 700 are provided along the length direction of the breakwater 300, and welding is performed between adjacent guardrails 700.

[0065] As a preferred embodiment, a viewing platform 800 is provided on the side of the breakwater 300 away from the sea.

[0066] In summary, the seawall ecological modular system provided in this embodiment has at least the following advantages compared to the existing technology:

[0067] (1) The 400mm hoisting technology of the ecological vegetation module structure can be installed quickly, which can reduce time costs and improve offshore construction efficiency.

[0068] (2) Plant varieties should be cultivated in a weak dynamic environment near the site in advance according to the site's salt tolerance and flood tolerance, so as to improve the plant survival rate and quickly establish the landscape.

[0069] (3) The plant community, combined with the ecological structure formed based on tidal changes, can better adapt to tidal waves, grow naturally, and have low artificial maintenance costs.

[0070] (4) The ecological vegetation module structure 400 is hoisted in the form of multi-layer steps to reduce the height difference and form a distinct landscape effect to beautify the seawall.

[0071] (5) Ecological vegetation module structure 400, gabion mesh has good water permeability and high porosity, which improves the plant habitat, is conducive to plant growth, effectively improves the biodiversity outside the seawall, and reduces the embankment effect.

[0072] (6) The terraced plant communities interact with different ecological units of intertidal plants such as salt marshes and mangroves, achieving important ecological benefits such as carbon sequestration, pollution control, and habitat improvement.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
