Description

Technical Field

[0001] The utility model belongs to the technical field of seawall slope protection and relates to a seawall slope protection structure. Background Art

[0002] Seawalls are embankments built along the coast to prevent tides and waves. They are important hydraulic structures in sea reclamation projects. Seawalls can prevent marine disasters and protect life and property.

[0003] Seawalls often need hard slope protection to resist the scouring of waves. The conventional method of seawall slope protection is to protect the waterside slope of the seawall with concrete. Although concrete slope protection can effectively prevent the scouring of waves, it is easy to cause problems such as reduced ecological diversity, weakened tide absorption function, and weakened water purification capacity.

[0004] Ecological seawalls are seawalls that are ecological, that is, they combine vegetation, environmentally friendly materials and construction methods to transform existing seawalls. On the basis of not reducing physical protection capabilities, they enhance their ecological connectivity and ecological service functions. While meeting the functions of resisting storm surges, resisting wave erosion, preventing soil erosion, maintaining biodiversity and improving water quality, they also have ecological functions and aesthetic values. The existing ecological seawalls reserve planting areas when building seawalls, and plants are planted in these areas. However, although this method can build an ecological seawall, after low tide, the planting soil in this area is swept into the sea, affecting the growth and replanting of plants.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Please refer to the attached Figure 1-3 , attached Figure 1-3 The following are respectively shown the three structures of seawall slope protection structures provided by the embodiments of the present application. Figure 1-3 It can be seen that the seawall slope protection structure provided in the embodiment of the present application includes a curb 01, a retaining wall 03, and an inclined embankment body 02 arranged between the curb 01 and the retaining wall 03. The curb 01 is arranged between the seawall body and the road surface, and the retaining wall 03 is arranged close to the sea to resist the hydraulic action and maintain the stability of the slope; at the same time, it can also prevent soil erosion and scouring, and prevent the occurrence of landslides or collapses. In the embodiment of the present application, the curb 01 and the retaining wall 03 can adopt existing structures. The inclined embankment body 02 is the main structure of the seawall, which mainly plays a protective role.

[0030] Along the inclined direction of the inclined embankment body 02, multiple rows of seawall ecological boxes 04 are arranged on the inclined embankment body 02, as shown in the attached Figure 1 The side of the drainage trough 2 in the seawall ecological box 04 faces the retaining wall 03 so as to discharge the seawater poured into the seawall ecological box 04 during high tide.

[0031] In addition, the inclined embankment 02 can also adopt a step structure in addition to the above-mentioned planar structure. Specifically, along the inclined direction of the inclined embankment 02, the inclined embankment 02 is provided with steps 05 of equal width and height at equal intervals from top to bottom, and a seawall ecological box 04 is placed on each step 05. In this case, multiple rows of seawall ecological boxes 04 are arranged in a multi-step manner, as shown in the attached figure. Figure 2 ,3 shown.

[0032] In the embodiment of the present application, when multiple rows of seawall eco-boxes 04 are arranged in a multi-step manner, the bottom of the upper seawall eco-box 04 partially overlaps with the top of the lower seawall eco-box 04, as shown in the attached Figure 2 As shown. This arrangement can place multiple layers of seawall eco-boxes 04, presenting different arrangements and placements of flowers and plants, and is suitable for seawalls with larger slopes. Alternatively, the bottom edge of the upper seawall eco-box 04 can overlap with the top edge of the lower seawall eco-box 04, as shown in the attached figure. Figure 3 Such a setting method can reduce the number of seawall eco-boxes 04 used, reduce construction costs, and is suitable for seawalls with smaller slopes.

[0033] Please refer to the attached Figure 4 , attached Figure 4 The first structural schematic diagram of the seawall eco-box provided in the embodiment of the present application is shown. Figure 4 It can be seen that the seawall ecological box provided in the embodiment of the present application includes a box body 1, a non-woven fabric 3, a gravel layer 4 and a soil layer 5.

[0034] Specifically, the box 1 is the main structure of the seawall eco-box, which is set to a square or trapezoidal structure. In order to facilitate the planting of plants inside the box 1, the top of the box 1 is opened. Since the seawall eco-box provided in the embodiment of the present application is applied to the seawall, in order to prevent the eco-box from being destroyed by the impact of seawater, the seawall eco-box adopts a concrete box prepared by concrete pouring. The setting of the concrete box also facilitates the pouring of the seawall eco-box and the seawall together, thereby enhancing the stability of the seawall.

[0035] When the tide rises, a large amount of seawater is discharged into the seawall eco-box, affecting the growth of plants. In order to prevent the accumulation of seawater in the seawall eco-box, a drainage groove 2 is provided at the bottom, side wall or the connection between the bottom and side wall of the box body 1 in the embodiment of the present application. Figure 4-6 As shown. The arrangement of the drainage groove 2 can discharge seawater, prevent seawater from accumulating in the eco-box, and is conducive to plant growth. When the seawall eco-box is installed on the seawall, the side of the box body 1 with the drainage groove 2 faces the sea to facilitate smooth drainage.

[0036] In order to adapt to different arrangements of the seawall eco-boxes on the seawall, drainage grooves 2 are provided at the bottom, side walls or the connection between the bottom and side walls of the box body 1 .

[0037] When the seawall eco-box 04 adopts Figure 1 In the arrangement structure shown in the figure, the drainage groove 2 is arranged at the bottom of the box body 1 and close to the side wall of the box body 1. Figure 4 At this time, the seawater poured into the box body 1 during high tide is discharged from the drainage groove 2 at the bottom of the box body 1 and then discharged along the inclined embankment body 02.

[0038] When the seawall eco-box 04 adopts Figure 2 , 3 In the arrangement structure shown in the figure, the drainage groove 2 is arranged on the side wall of the box body 1 and close to the bottom of the box body 1. Figure 5 At this time, the seawater poured into the box 1 at high tide is discharged from the drainage groove 2 on the side wall of the upper box 1 into the lower box 1, and so on, until the seawater in the last layer of seawall ecological box 04 is discharged from the drainage groove 2 along the inclined embankment body 02.

[0039] When the seawall eco-box 04 adopts Figure 1-3 In any of the arrangement structures shown in the figure, the drainage groove 2 can be arranged at the connection between the bottom of the box body 1 and the side wall, as shown in the figure. Figure 6 At this time, the seawater poured into the box body 1 during high tide can be discharged from the drainage groove 2 at the bottom of the box body 1, or can be discharged into the box body 1 of the next layer from the drainage groove 2 on the side wall of the box body 1 of the upper layer.

[0040] Furthermore, when the seawall is a flat slope, in order to facilitate drainage of the seawall eco-box, a bracket 8 is provided at the bottom of the box body 1 in the embodiment of the present application. The setting of the bracket 8 can make a certain distance between the box body 1 and the seawall slope, thereby facilitating drainage from the drainage groove 2 at the bottom of the box body 1.

[0041] In the embodiment of the present application, non-woven fabric 3 is laid inside the box body 1. Specifically, non-woven fabric 3 is laid on the bottom of the box body 1 and the surrounding side walls. Non-woven fabric 3 has heat-resistant properties, which can dissipate the heat inside the seawall eco-box to prevent the roots of plants from rotting due to excessive heat. Non-woven fabric 3 also has water-repellent properties, which can keep the water and soil inside the box body 1 moist, which is conducive to plant growth. Non-woven fabric 3 also has air permeability, which is conducive to plant roots absorbing oxygen and producing nitrogen. In addition, when the seawater tide hits the seawall eco-box, non-woven fabric 3 can also filter muddy water to prevent the formula soil in the seawall eco-box from being washed away.

[0042] A gravel layer 4 and a soil layer 5 are provided in the nonwoven fabric 3, and the soil layer 5 is located above the gravel layer 4. The laying of gravel in the gravel layer 4 can facilitate drainage, prevent seawater from accumulating in the eco-box, and facilitate plant growth. In the embodiment of the present application, the laying thickness of the gravel layer 4 is 10-12 cm.

[0043] In order to prevent the formula soil in the seawall ecological box from being washed away, a gravel layer 6 is also provided above the soil layer 5. The provision of the gravel layer 6 is also conducive to the breathing and ventilation of the plants. Preferably, the particle size of the gravel in the gravel layer 6 is about 3 cm. Further, in order to prevent the gravel in the gravel layer 6 from being washed away by seawater, a fixed net 7 is laid on the gravel layer 6, and the mesh diameter of the fixed net 7 is smaller than the particle size of the gravel in the gravel layer 6, so as to achieve the purpose of fixing the gravel.

[0044] In the seawall slope protection structure provided in the embodiment of the present application, multiple rows of seawall eco-boxes 04 are arranged on the inclined embankment body 02 between the curb 01 and the retaining wall 03, so as to facilitate the planting of plants through the seawall eco-boxes 04. In the seawall eco-box 04, the non-woven fabric 3 laid inside the box 1 can block heat, keep the water and soil moist, and also facilitate the root system to absorb oxygen and produce nitrogen. In addition, when seawater impacts the eco-box, the non-woven fabric 3 can also filter muddy water to prevent the formula soil in the seawall eco-box from being washed away. The seawall slope protection structure provided in the embodiment of the present application has the characteristics of simple structure, water drainage, and keeping the water and soil moist, which is conducive to plant growth and the rooting of replanted plants.

[0045] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
