Description

Technical Field

[0001] This invention relates to the field of windbreak and sand-fixing equipment technology, and in particular to a sand-fixing vegetation slope protection device for preventing soil erosion. Background Technology

[0002] Slope protection refers to all paving and planting work done on slopes to prevent erosion. Soil and water erosion refers to the damage and loss of soil and water resources and land productivity caused by natural forces such as water, wind, gravity, and freeze-thaw cycles, as well as human activities. This includes surface erosion and water loss. Among these, water erosion is more serious, especially on the concave banks of rivers, which are eroded by water flow year by year, as well as by water erosion caused by rainstorms. This washes away the soil, causing the riverbanks to collapse and damaging bridges, embankments, and other structures.

[0003] In today's context of increasing emphasis on ecological slope protection, slope protection mainly includes the following categories: Directly planted vegetation slope protection is simple to construct and inexpensive, but it has poor initial soil stabilization and water retention capacity, and its unstable foundation makes it easy to be eroded and displaced. Eco-bag slope protection uses artificial geotextile to make ecological bags. Plants grow in the ecological bags filled with soil to protect the slope and restore the environment. However, its disadvantages are also very obvious. If the ecological bags are directly stacked on a slope with a certain angle, once the surface structure of the slope is loose or the slope is steep, the ecological bags are prone to sliding and becoming unstable over time, resulting in uneven vegetation distribution and a significant reduction in soil stabilization capacity. Grid ecological slope protection is formed by using materials such as bricks, stones, concrete blocks, and cast-in-place concrete to form a grid. Plants are then planted within the grid to create a comprehensive slope protection system that combines the grid with vegetation. It combines engineering structures with vegetation slope protection, resulting in significant effects. However, its disadvantages include complex preparation and bulky structure, which affects construction and installation efficiency and safety. Summary of the Invention

[0004] To address the above problems, this invention provides a sand-fixing vegetation slope protection device for preventing soil erosion. It combines a grid pattern covering the slope surface with vegetation slope protection, while also achieving efficient construction and installation and reducing processing costs. It achieves reliable and significant soil stabilization and water retention, and is easy to adjust and highly adaptable.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A sand-fixing vegetation slope protection device for preventing soil erosion includes multiple connecting bars evenly spaced along the slope surface, with multiple slope protection unit plates spaced apart on the connecting bars. Each slope protection unit plate includes a strip, with bases on both sides of the strip. The connecting bars pass through through holes on the bases and have knots at both ends of the through holes for limiting the slope protection unit plates. A bottom groove is provided on the bottom surface of the strip, and a moisture-retaining block is provided in the bottom groove. A through groove is opened laterally on the top surface of the strip, and multiple positioning water guide rods are provided in the through groove, with the upper part located in the moisture-retaining block and the lower part embedded in the slope soil. Each positioning water guide rod includes a nail head at the top and a nail tail in the shape of a pointed cone at the tail end. A water guide pipe is provided between the nail head and the nail tail, and the water guide pipe is hollow inside with multiple water passage holes on the side. An adjustment window is opened on the outside of the base to connect to the middle of the through hole, and the connecting bars located in the through hole can extend outward through the adjustment window. Knot grooves for accommodating the knots are provided at both ends of the through hole.

[0006] As a further improvement to the above solution, the moisturizing block is provided with water storage holes, and its two ends along the length of the connecting rib are provided with customized edges with a specific shape.

[0007] As a further improvement to the above solution, the moisturizing block is a sponge block; the edge of the customized edge contour is an inner arc shape, and the strip has a limiting edge for limiting the position on the bottom surface of the moisturizing block.

[0008] As a further improvement to the above solution, the top of the connecting bar is provided with a fixing member fixed to the top of the slope; the fixing member includes an end connected to the top of the connecting bar, and a ground-fixing structure is provided between the end and the top of the slope.

[0009] As a further improvement to the above solution, a sign for recording information is provided on the end, and the grounding structure is an expansion nail.

[0010] As a further improvement to the above solution, an ecological bag is provided between the slope protection unit panels, and a bag-fixing strip for limiting the ecological bag is connected between the positioning water guide rods located on the upper and lower sides of the ecological bag.

[0011] As a further improvement to the above scheme, the slope protection unit panels connected by the connecting bars are evenly spaced and arranged on both sides of the connecting bars, and the area between multiple longitudinally and transversely adjacent slope protection unit panels is the area for direct growth of sand-fixing vegetation or the area for placing ecological bags.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: Multiple slope protection unit panels are set on the slope to form a grid structure, and the slope protection unit panels are connected and fixed with connecting bars; at the same time, positioning water guide rods that connect moisture-retaining blocks are set, and their lower parts are inserted into the slope soil. While fixing the slope protection unit panels to the slope surface, continuous and in-depth soil watering is completed, which is conducive to the growth of vegetation between the grids and combines them to achieve composite slope protection.

[0013] The moisturizing block is a sponge block that can retain moisture and water, and improve the bonding strength between the bottom surface of the slope protection unit board and the slope surface. The positioning water guide rod can also be easily inserted into the soil through the moisturizing block. The upper part absorbs water from the sponge through the water passage hole and sends it to the lower part, and then sends it to the vicinity of the vegetation roots through the water passage hole, which promotes vegetation growth and completes the reliable fixation of the slope protection unit board on the slope.

[0014] The setting of rib knots and through-rib holes can firmly limit the slope protection unit panels to the connecting ribs. At the same time, the position of the rib knots can be adjusted. If the distance between the rib knots is too long, causing the slope protection unit panels to slide up and down, the excess connecting ribs can be pulled out and knotted by adjusting the window to ensure that the rib knots are firmly set in the knot groove and are not subject to wear and sunlight, thereby improving the structural strength and durability.

[0015] Customized edge design enhances the overall neatness and aesthetics of the device while increasing the contact area between the edge and the eco-bag, thereby further stabilizing the position of the eco-bag and avoiding the loss of manpower and materials for later replanting and maintenance.

[0016] The installation of fasteners can improve the distribution and adjustment adaptability of the device. Depending on the width of the slope protection unit panels, the spacing between the connecting bars can be adjusted by fixing the fasteners. In addition, the sign can record the construction and maintenance information of the slope protection at that location, which facilitates the rapid and reliable development of subsequent related work.
