Description

Technical Field

[0001] The utility model relates to the technical field of waterway slope protection, in particular to a slope protection structure for a waterway slope. Background Art

[0002] Channel slope refers to the transition area between the water body and the coastline in the field of water transportation, that is, the slope with a certain slope on both sides of the channel. The protection of channel slope is crucial to the safety and smoothness of the channel. Therefore, reasonable demarcation of the protection range of channel slope is an important measure to ensure the stability of the slope and the normal operation of the channel.

[0003] In recent years, ecological slope protection technology has been used in the management of inland waterways to repair the ecological environment around inland waterways, improve the landscape around the waterways, enrich the biodiversity of rivers and slopes, and promote the sustainable development of inland waterways. Ecological slope protection technology usually includes slope leveling, support structure construction and vegetation planting. Specifically, the slope is leveled by filling soil, digging and adjusting the terrain to achieve the slope and shape required by the design; support structures such as geogrids and steel mesh are set on the slope to enhance the bearing capacity of the slope. When planting vegetation on the slope, choose appropriate plant species and density, and pay attention to ensuring the growth and ecological function of the plants.

[0004] At present, plants are divided into several units through prefabricated slope protection structures to increase the soil-fixing effect. Since the slopes are hit by waves in the waterway, if the drainage of the plants is not done well, the growth of the plants and the soil-fixing ability will be affected, the soil-fixing effect will still decrease, and it will not be conducive to the growth of the plants.

[0024] In order to better understand the technical content of the present invention, specific embodiments are described below in conjunction with the accompanying drawings.

[0025] Combination Figure 1 As shown, the first aspect of the utility model proposes a slope protection structure for a waterway slope, comprising a plurality of slope protection units 10 distributed on the slope surface in a matrix manner, the slope protection units 10 being laid on the surface of the slope with a predetermined slope, and after the slope is leveled and supported, the slope protection units 10 are laid layer by layer from low to high, wherein the direction from the waterway to the slope bank is the first direction, the direction parallel to the waterway is the second direction, the first direction and the second direction are perpendicular, and the slope protection units 10 are closely arranged in a matrix along the first direction and the second direction.

[0026] Among them, each slope protection unit 10 includes a base plate 11, a water retaining ring 12 and a soil fixing ring 13. Along the first direction, a pressure plate 111 is provided at the first end of the base plate 11, and a supporting step 112 is provided at the second end. When the slope protection units 10 are spliced ​​along the first direction, the pressure plates 111 and the supporting steps 112 of adjacent slope protection units 10 abut against each other. When spliced ​​along the second direction, they abut against each other through the side walls of the base plate 11.

[0027] The water retaining ring 12 is connected to the upper end surface of the bottom plate 11, and the bottom plate 11 is provided with a plurality of through holes 113 in the area within the water retaining ring 12; the soil fixing ring 13 is connected to the lower end surface of the bottom plate 11, and corresponding to the position distribution of the water retaining ring 12, a plant growth area 101 is formed on the inner side of the water retaining ring 12, and a plant planting area 131 is formed on the inner side of the soil fixing ring 13, and the plant growth area 101 and the plant planting area 131 are connected through the through hole 113.

[0028] In this way, when the slope protection unit 10 is arranged on the slope, the plant planting area 131 can accommodate soil for growing plants, and seeds can be sprinkled in the through holes 113, such as plants with good soil-fixing ability such as Bermuda grass and daylilies. Multiple plant growth areas 101 are separated by water retaining rings 12, and drainage channels 102 are formed between adjacent plant growth areas 101, and multiple water retaining rings 12 shield each other. When rainwater or waves wash the slope protection unit, they can flow through the drainage channel 102, thereby reducing the amount of water retained in the plant growth area 101.

[0029] Preferably, the diameter of the water retaining ring 12 is 1 / 2-1 / 3 of the width of the bottom plate 11. The drainage channel 102 formed in this way has a large width, which can form a better drainage effect.

[0030] Furthermore, a circular area is formed in the water retaining ring 12. In the circular area, the area close to the pressure plate 111 is defined as the first area, and the area far from the pressure plate 111 is defined as the second area. The through holes 113 are distributed in the second area.

[0031] In this way, when water flows into the water retaining ring 12 , it will also flow to the first area due to gravity. Therefore, arranging the through hole 113 in the second area can also prevent water from entering the through hole 113 .

[0032] In an optional embodiment, an area ratio of the second region to the first region is greater than 3:1.

[0033] Further, the outer wall of the water retaining ring 12 is provided with a drainage groove or drainage hole 121 at a position corresponding to the first area. The drainage groove or drainage hole 121 is located at the bottom of the water retaining ring 12. In this way, the water retained in the first area can be discharged from the drainage groove or drainage hole 121 in time.

[0034] Furthermore, in order to reduce soil loss caused by repeated scouring of water waves, a baffle 14 extending downward is provided at the first end of the bottom plate 11, the baffle 14 coincides with the outer edge of the soil fixing ring 13, and the width of the baffle 14 is the same as the width of the bottom plate 11. In this way, each row of slope protection units 10 is spliced ​​to form a horizontal baffle wall, and the baffle 14 can prevent soil from moving downward along the slope with the water flow.

[0035] Further, the bottom of the baffle 14 is provided with micropores 141 penetrating the baffle 14 , and the axial direction of the micropores 141 is along the first direction. Optionally, the size of the micropores 141 is 2-3 mm, which can effectively drain water and prevent soil and sand from being discharged from the micropores 141 .

[0036] Optionally, the bottom plate 11, the water retaining ring 12, the soil fixing ring 13 and the baffle 14 are an integrated structure and are prefabricated with concrete.

[0037] In combination with the above embodiments, the slope protection unit of the utility model includes a water retaining ring and a soil consolidation ring. The soil consolidation ring forms a soil consolidation area below the base plate for storing soil for plant growth. The water retaining ring isolates the water flow above the base plate so that the water flow on the slope can quickly flow out from the drainage channel between the water retaining rings. This design makes the plants in the water retaining ring less affected by the impact of waves and water, which is conducive to growth and soil consolidation, thereby ensuring the ecological function of the slope.

[0038] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. A person with ordinary knowledge in the technical field to which the present invention belongs may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the definition of the claims.
