Description

Technical Field

[0001] This utility model relates to the field of river sand mining and management technology, specifically to an ecological restoration structure for river sand mining pits. Background Technology

[0002] Riverbeds have abundant sand and gravel resources, and river sand is an excellent building material. With the increasing demand for river sand in the construction market, the direct cost of mining river sand is low, and there is a huge profit margin in sand mining. However, sand pits formed by excessive mining in unreasonable areas, at inappropriate times, and in large quantities have adverse effects on river stability, flood control safety, protection of the river water environment and aquatic ecology, and the normal operation of river-related facilities. Therefore, ecological restoration structures are needed to restore the riverbed. For example, the ecological water storage type sand pit restoration system authorized by announcement number "CN214738653U" includes a sand pit, wire mesh cage, ecological bag, composite geotextile, excavated soil and carbon fiber ecological grass, isolation fence, etc. The original sand pit is sloped, with a slope of no less than 1:5 on both sides and a slope of no less than 1:10 connecting with upstream and downstream areas. After sloping, a composite geotextile is laid on the surface of the slope, followed by backfill soil. A gabion is then laid on the backfill soil surface, with ecological bags placed inside the gabions. The ecological bags contain grass seeds, planting soil, and sand mining waste. The gabions are secured with wire and laid flat on the sides and bottom of the sand pit. Carbon fiber ecological grass is laid on the bottom gabions. A protective netting fence is placed on top of the sand pit slope. This invention enables ecological restoration of sand pits in river channels, where the gabion ecological bags not only have good erosion control effects;

[0003] When using the current ecological restoration structure for river sand mining pits, the wire mesh ecological bags at the bottom of the sand mining pit are arranged in a staggered layer, which helps to improve the anti-erosion effect. The wire mesh cages are tied together to form a unified whole, which enhances the protective function of the flexible wire mesh ecological bags and can effectively prevent soil erosion caused by water flow scouring or rain splash erosion. Grass seeds are placed inside the ecological bags, and the roots of the grass grow to fix the soil and water, further preventing soil erosion.

[0004] Traditional ecological restoration structures for river sand mining pits involve placing grass seeds into wire mesh cages via ecological bags, which then secure the bags. As the grass grows, its roots penetrate the soil, helping to stabilize the soil and prevent soil erosion. However, since the soil needs to be placed into multiple ecological bags to provide space for the grass seeds to grow, the process of filling the ecological bags with soil is cumbersome and not conducive to the widespread use of ecological restoration structures. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an ecological restoration structure for river sand mining pits. It solves the problem that traditional ecological restoration structures for river sand mining pits involve placing grass seeds into wire mesh cages via ecological bags, securing the bags with the wire mesh cages, and allowing the grass roots to anchor in the soil and prevent soil erosion. However, the process of filling the ecological bags with soil is cumbersome and hinders the widespread adoption of this ecological restoration structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ecological restoration structure for river sand mining pits, comprising a base plate, with multiple vertical rods fixedly connected to the top of the base plate, and anti-loss devices installed on the inner walls of the multiple vertical rods. The anti-loss devices include: multiple filter plates, all movably connected to the inner walls of the multiple vertical rods; and multiple planting boxes, all installed on the inner walls of the base plate. The filter plates are capable of filtering sediment from the river water flow into the planting boxes.

[0007] Preferably, a maintenance device is provided at the top of the plurality of vertical poles, the maintenance device comprising: multiple connecting rods respectively installed at the top of the plurality of vertical poles; and multiple artificial reefs respectively installed at the bottom of the plurality of connecting rods; wherein the connecting rods fix the artificial reefs to the outer wall of the vertical poles.

[0008] Preferably, the inner wall of the base plate is fitted with two mounting nails by bolts.

[0009] Preferably, the bottom of the mounting pin is machined with a tapered structure.

[0010] Preferably, the outer wall of the vertical rod is provided with a water-blocking device, which includes: two sliders, each installed on the outer wall of the two vertical rods; two outer frames, each movably connected to the outer wall of the two sliders and movably connected to the outer wall of the two vertical rods; and two water-blocking plates, each installed on the outer wall of the two outer frames and abutting against the top of the bottom plate; wherein the outer frames limit the water-blocking plates through the sliders.

[0011] Beneficial effects

[0012] This utility model provides an ecological restoration structure for river sand mining pits. It has the following advantages: The ecological restoration structure uses bolts and mounting nails to fix the base plate inside the riverbed. An anti-erosion device prevents soil loss. A small amount of soil and aquatic plant seeds are added to the planting box, and a filter plate filters the silt from the river water. The filtered silt is stored inside the planting box to provide nutrients for the aquatic plant seeds. This eliminates the need to pack soil and seeds into multiple ecological bags, facilitating the widespread application of the ecological restoration structure.

[0013] Artificial reefs are fixed to the outer wall of vertical poles by maintenance devices, providing habitats for fish in the river and accelerating the restoration of the ecological environment for fish in the river. Water-blocking devices allow river water to pass through the interior of the anti-loss device, reducing soil erosion in the river. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0021] In the traditional ecological restoration structure for river sand mining pits, grass seeds are placed inside wire mesh cages through ecological bags during use. The wire mesh cages fix the ecological bags in place, and the roots of the grass grow into the soil, which helps to fix the soil and prevent soil erosion. Since the soil needs to be put into multiple ecological bags to provide growing space for the grass seeds, the process of putting the soil into the ecological bags is quite cumbersome and not convenient for the widespread use of the ecological restoration structure.

[0022] In view of this, the present invention provides an ecological restoration structure for river sand mining pits. The base plate is fixed to the inside of the riverbed using bolts and mounting nails. Soil loss is prevented by an anti-loss device. A small amount of soil and aquatic plant seeds are added into the planting box. The filter plate can filter the silt in the river water, and the filtered silt is stored in the planting box to provide nutrients for the aquatic plant seeds. It is not necessary to put the soil and seeds into multiple ecological bags, which facilitates the promotion and use of the ecological restoration structure.

[0023] Example 1: By Figure 1 , 2 As can be seen from points 3 and 4, an ecological restoration structure for river sand mining pits includes a base plate 1. Multiple vertical rods 2 are fixedly connected to the top of the base plate 1. An anti-loss device 3 is installed on the inner wall of the multiple vertical rods 2.

The filter plate 31 filters the silt in the water and stores the silt inside the planting box 32. Aquatic plant seeds are placed inside the planting box 32. The silt can provide more nutrients for the aquatic plant seeds. The aquatic plant seeds pass through the bottom of the filter screen of the planting box 32, take root and enter the riverbed, which can prevent soil erosion inside the riverbed.

[0028] Furthermore, two mounting nails 6 are installed on the inner wall of the base plate 1 by bolts 7;

[0029] In the specific implementation process, it is worth noting that bolt 7, together with mounting nail 6, fixes the base plate 1;

[0030] Furthermore, the bottom of the mounting nail 6 is machined with a tapered structure;

[0031] In the specific implementation process, it is worth noting that the conical structure makes it easy to fix the mounting nail 6 inside the river channel;

[0032] Specifically, based on the above embodiment 1, the staff fixed the artificial reef 42 at the bottom of the connecting rod 41 to the outer wall of the vertical rod 2. The artificial reef 42 can provide a habitat for fish in the river and further accelerate the speed of ecological restoration. The base plate 1 is fixed to the river by bolts 7 and mounting nails 6.

[0033] Example 3: From Figure 1 , 2 As can be seen from points 3 and 4, the outer wall of the vertical rod 2 is provided with a water-blocking device 5. The water-blocking device 5 includes: two sliders 51, which are respectively installed on the outer wall of the two vertical rods 2; two outer frames 52, which are respectively movably connected to the outer wall of the two sliders 51 and respectively movably connected to the outer wall of the two vertical rods 2; and two water-blocking plates 53, which are respectively installed on the outer wall of the two outer frames 52 and abut against the top of the bottom plate 1; wherein, the outer frame 52 limits the water-blocking plate 53 through the sliders 51.

[0034] In the specific implementation process, it is worth noting that the outer frame 52 fixes the water baffle 53 to the outer wall of the vertical rod 2 by means of the slider 51;

[0035] Specifically, based on the above embodiment 1, the outer frame 52 is fitted onto the outer wall of the vertical rod 2, and the outer frame 52 is fixed to the water baffle 53 by the slider 51. The water baffle 53 can collect the water in the river and allow the river water to pass through the anti-loss device 3.
