Description

Technical Field

[0001] The utility model belongs to the technical field of ecological slope protection structures, and particularly relates to an ecological slope protection structure for coastal zones. Background Technique

[0002] Slope protection refers to the general term for various paving and planting done on the slope surface to prevent the slope from being scoured. In coastal areas, the use of coastal zone slope protection is more extensive.

[0003] In the Chinese patent with the publication number CN217923391U, an ecological slope protection structure for coastal zones is disclosed. The utility model adopts a sloping revetment, and a thick rubble bed is used at the bottom, which greatly improves the stability, extends the service life, and reduces the construction and maintenance costs; the bottom protection concrete blocks used can improve the strength of the revetment, and the backfilled gravel changes the slope, making the processing more convenient. At the same time, vegetation can be planted on the pavement to form an ecological slope protection.

[0004] When the above-mentioned ecological slope protection structure for coastal zones is in use, the pressure generated when the sea waves strike the landscape layer will directly damage the plants planted in the grass brick layer, causing frequent bending between the stems and leaves and the roots of the plants, resulting in difficulty for the plants to take root and affecting the effect of plant slope fixation. Therefore, an ecological slope protection structure for coastal zones is proposed to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an ecological slope protection structure for coastal zones to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] An ecological slope protection structure for coastal zones, comprising:

[0008] Geotextile, which is laid on the foundation bed formed by the slope surface of the coast and the flat surface of the seabed;

[0009] Concrete foot protection, which is laid on the flat surface of the seabed, and one side of its bottom presses on the geotextile;

[0010] Slope protection section, which is arranged on the upper surface of the geotextile and is set as three spaced sloping surfaces. The slope protection section is sequentially provided with a graded gravel layer, a two-piece stone cushion layer, a dry-laid stone block layer, a concrete layer, and a grass brick layer from bottom to top;

[0011] Wave-blocking columns, which are fixedly installed on the top of the concrete foot protection;

[0012] Retaining wall, which is arranged on the top of the slope protection section and is arranged above the dry-laid stone block layer.

[0013] Preferably, the height of the wave-blocking column exceeds the height of the bottom of the uppermost slope surface.

[0014] Preferably, the wave-blocking column is provided with a water-passing notch in the direction perpendicular to the coastline, and tide-blocking holes of different sizes are provided in the direction parallel to the coastline.

[0015] Preferably, both side surfaces of the wave-blocking column are inclined surfaces.

[0016] Preferably, the grass-planting brick layer is adhesively fixed on the upper surface of the concrete layer, and vegetation is planted between adjacent grass-planting bricks.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] (1) By providing the wave-blocking column, the present utility model can reduce the impact force of the sea wave on the slope protection section, and prevent the vegetation planted in the grass-planting brick layer from being washed away and damaged by the sea wave.

[0019] (2) By fixing the grass-planting bricks on the concrete layer and providing tide-blocking holes on the side surface of the wave-blocking column, the present utility model can not only protect the root systems of the vegetation from being washed away by the sea wave, but also provide a space for aquatic organisms to inhabit.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. It should be noted that the drawings are schematic and not drawn to scale. For the sake of clarity and convenience in the figure, the relative sizes and proportions of the parts shown in the figure are exaggerated or reduced in size and illustrated, and any size is only exemplary and not limiting.

[0025] Embodiment:

[0026] Refer to Figure 1 and Figure 2As shown in the figure, a coastal ecological slope protection structure includes:

[0027] A geotextile 1, which is laid on the foundation bed formed by the slope surface of the coast and the flat surface of the seabed;

[0028] A concrete foot protection 2, which is laid on the flat surface of the seabed, and one side of its bottom presses on the geotextile 1;

[0029] A slope protection section, which is arranged on the upper surface of the geotextile 1, and is set as three spaced slope surfaces. The slope protection section is successively arranged as a graded crushed stone layer 3, a two-piece stone cushion layer 4, a dry-laid stone block layer 5, a concrete layer 6 and a grass-planting brick layer 7 from bottom to top;

[0030] A wave-blocking column 8, which is fixedly installed on the top of the concrete foot protection 2;

[0031] A retaining wall 9, which is arranged on the top of the slope protection section and is above the dry-laid stone block layer 5.

[0032] Specifically, as can be seen from Figure 1 the height of the wave-blocking column 8 exceeds the height of the bottom of the topmost slope surface.

[0033] Specifically, the grass-planting brick layer 7 is adhesively fixed on the upper surface of the concrete layer 6, and vegetation is planted between adjacent grass-planting bricks.

[0034] As can be seen from the above, by setting the grass-planting brick layer 7, it is convenient to plant vegetation. At the same time, the gaps between adjacent grass-planting bricks can also serve as habitats for small aquatic fish after planting vegetation. By setting the wave-blocking column 8, it can block the impact of sea waves on the slope protection section and reduce the impact on the slope protection section.

[0035] Specifically, as can be seen from Figure 2 the wave-blocking column 8 is provided with a water passing notch 81 in the direction perpendicular to the coastline, and is provided with tide-blocking holes 82 of different sizes in the direction parallel to the coastline.

[0036] As can be seen from the above, the setting of the water passing notch 81 is used to allow seawater to flow through and is also convenient for shallow-sea animals to pass through the wave-blocking column 8. The setting of the tide-blocking holes 82 can provide habitat space for shallow-sea organisms and reduce the probability of shallow-sea organisms being washed ashore during high tide.

[0037] Specifically, as can be seen from Figure 1 the two side surfaces of the wave-blocking column 8 are both set as inclined surfaces.

[0038] As can be seen from the above, the setting of the inclined surfaces can reduce the impact force of the sea waves on the wave-blocking column 8.
