Description

Technical Field

[0001] This utility model relates to the field of seawall technology, and in particular to a seawall that does not intrude into the coastline. Background Technology

[0002] Terminology Explanation:

[0003] Seawall: A dike or levee built to protect a protected area from storm surges (floods) and waves.

[0004] Coastline: The line marking the boundary between land and sea at the average high tide of the multi-year spring tide.

[0005] A wave wall is a wall installed at the front edge of a dike to prevent waves from overturning the top of the dike.

[0006] Overpass volume: The unit width of the flow rate of waves overpassing the top of the dike.

[0007] Coastal areas are frequently hit by storm surges, which not only endanger people's lives but also cause serious economic losses. Storm surge dike projects are the most direct and effective safety measure to cope with storm surge disasters.

[0008] Seawall construction is often constrained by the existing conditions of the area on the leeward side and the sea-use boundary lines on the coastal side. On the one hand, coastal areas are economically developed, and the leeward side of seawalls often has municipal or civil facilities such as roads, parks, and buildings, making it impossible to extend the seawall to the leeward side. On the other hand, people highly value ecological civilization construction, and society encourages the implementation of coastal protection and restoration projects, the construction of ecological seawalls, and the enhancement of the ability to resist marine disasters. Seawall construction should focus on the leeward side to avoid damaging the coastal beaches and ecological functions.

[0009] Based on domestic and international experience in seawall construction, and according to their cross-sectional shape, seawalls directly facing the sea are generally classified into three basic types: sloping type, steep wall type, and hybrid type. Sloping type: The seawall foundation occupies a large area, requiring more fill material; when the slope on the seaward side is gentle, the calculated wave run-up value is larger, resulting in a correspondingly higher seawall. Steep wall type: Foundation stress is more concentrated; the different material properties of the wall and the fill material behind it can easily cause a large differential settlement between the wall and the area behind it, and wave backflow can easily cause erosion at the corners. Hybrid type: A combination of sloping and steep wall types.

[0010] Given the limitations imposed on seawall construction by the existing conditions of the area on the back side of the sea and the sea use boundary line on the front side, traditional seawall types are difficult to fully apply. Utility Model Content

[0034] In an exemplary embodiment, the subbase 1 is formed by casting plain concrete. The inner side of the upper embankment step 6 is a park or other architectural structure 100. For example... Figure 1 , 2 As shown

[0035] In an exemplary embodiment, the base plate and the seaside side wall are provided with water exchange holes or wave-damping holes. In an exemplary embodiment, the water exchange holes or wave-damping holes are arranged in a staggered pattern with a spacing of 1m. In an exemplary embodiment, the water exchange holes or wave-damping holes are circular holes with an inner diameter of 200mm.

[0036] In an exemplary embodiment, each of the starting and ending sections of the seawall is provided with an end plate 13 to enclose the empty box structure. In an exemplary embodiment, the end plate, the bottom plate, the back-sea side wall, the sea-facing side wall, the upper seawall steps, and the waterfront platform are integral concrete structures.

[0037] In an exemplary embodiment, a settlement joint 12 is provided every 8 to 12 meters along the seawall, and the width of the settlement joint is 20 mm. In an exemplary embodiment, the settlement joint 12 is filled with polyethylene closed-cell foam board 14.

[0038] In an exemplary embodiment of this application, the seawall that does not intrude into the coastline can be completed or implemented through the following steps during construction;

[0039] 1) Pour plain concrete for foundation layer 1.

[0040] 2) After the foundation layer 1 is completed, the formwork 8 that forms the base plate 2 is installed, the reinforcing bars are tied, and the concrete is poured.

[0041] 3) After the concrete of the base slab 2 reaches the design strength, the formwork 8 is removed.

[0042] 4) Install the formwork 9, tie the reinforcing bars, and pour the concrete for the sea-facing side wall 3, the sea-facing side wall 4, and the inverted arc wave-breaking wall 5; among them, when pouring the starting and ending sections of the seawall, install the end plate 13 formwork, tie the reinforcing bars, and pour the concrete.

[0043] 5) After the concrete of the back-sea side wall 3, the sea-facing side wall 4, and the inverted arc wave-breaking wall 5 reaches the design strength, the formwork 9 is removed.

[0044] 6) Install the formwork 10, tie the reinforcing bars, and pour the concrete for the steps 6 and the waterfront platform 7.

[0046] 8).

[0047] In this embodiment of the utility model, φ200 (unit mm) water exchange holes (wave-dissipating holes) 11 are designed and poured into the base plate 2 and the seaside side wall 4. The water exchange holes (wave-dissipating holes) are spaced 1m apart and arranged in a quincunx pattern.

[0048] The novel seawall in the exemplary embodiments of this application is suitable for situations where land use is limited on the seaward and leeward sides, and has the following advantages compared with traditional seawall types:

[0049] 1) Do not encroach on the coastline and minimize ecological disturbance as much as possible.

[0050] 2) The area occupied on the back side of the sea is very small and will not affect the existing facilities on the back side of the sea.

[0051] 3) The empty box structure has low base stress and strong adaptability to soft soil.

[0052] 4) It is equipped with water exchange holes (wave-dissipating holes). When the tide rises, seawater enters the seawall through the water exchange holes (wave-dissipating holes). The weight of the water inside the seawall can offset part of the buoyancy, ensuring the seawall's anti-buoyancy stability.

[0053] 5) The anti-arc wave wall and water exchange hole (wave-dissipating hole) have a good wave-dissipating effect and can effectively reduce the amount of overtopping waves.

[0054] 6) Most of the existing seawall slopes and wave-dissipating facilities can be preserved and utilized, saving investment.

[0055] Once the seawall in the exemplary embodiment of this application meets the standards, it can improve the safety and reliability of flood prevention, reduce the threat of storm surges to coastal areas, effectively protect people's lives and property, maintain social stability, improve the coastal production and living environment, and promote the development of eco-leisure tourism, thus having significant social, economic and environmental benefits.
