Description

Technical Field

[0001] This invention relates to the field of retaining wall technology for intercepting ditches, specifically to a retaining device for ecological restoration of soil and water conservation in waterfront areas and its usage method. Background Technology

[0002] In water and soil conservation and ecological restoration work in waterfront areas, non-point source pollution caused by soil erosion is a prominent problem, causing serious damage to the ecological environment. Currently, while end-of-pipe pollution control and reduction technologies for non-point source pollution caused by soil erosion have achieved some success in pollutant control—for example, showing significant effects on permanganate index, chemical oxygen demand, ammonia nitrogen, total phosphorus, total nitrogen, and nitrate nitrogen—and can effectively reduce the degree of non-point source pollution caused by soil erosion, these technologies still have limitations. They have little impact on pH values ​​and their interception effect on fluoride and chlorine-containing pollutants is not significant.

[0003] Meanwhile, among existing ecological restoration methods, constructed wetlands play a primary role in reducing total phosphorus and ammonia nitrogen, effectively intercepting phosphorus and nitrogen-containing pollutants, reducing nutrients in water bodies, and preventing eutrophication. Ecological purification ponds and ecological interception ditches have significant effects on the degradation of organic pollutants. Ecological purification ponds utilize plant roots and soil filtration, while ecological interception ditches rely on the combined action of plants and microorganisms, demonstrating outstanding performance in degrading organic pollutants and deepening denitrification. The three form a complementary organic whole.

[0004] However, in practical applications, there is a lack of effective comprehensive solutions for retaining soil in waterfront ditches, addressing the need for people to cross ditches, and planting vegetation near ditches to enhance physical filtration and preliminary biodegradation. Existing ditches may suffer from problems such as loose connections and limited functionality, failing to adequately meet the diverse needs of soil and water conservation and ecological restoration in waterfront areas.

[0005] Therefore, developing a retaining device for soil and water conservation and ecological restoration in waterfront areas is of great practical significance. Summary of the Invention

[0006] The purpose of this invention is to provide a retaining device and its method of use for ecological restoration of soil and water conservation in waterfront areas, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a retaining device for ecological restoration of soil and water conservation in waterfront areas, comprising a ditch retaining plate, wherein an installation groove is provided on the top surface of one side of the ditch retaining plate, a suspension plate is rotatably connected inside the installation groove, and an overlap groove is provided on the top surface of the other side of the ditch retaining plate, wherein after the suspension plate rotates, one end of the suspension plate extends into the overlap groove, and multiple planting grooves are provided on the surface of the suspension plate.

[0008] Preferably, splicing grooves are respectively formed at both ends of the ditch retaining plate. The splicing groove is located on the outer ring surface at one end of the ditch retaining plate, and the splicing groove is located on the inner ring surface at the other end of the ditch retaining plate. Two ditch retaining plates are spliced in a staggered manner through the splicing grooves.

[0009] Preferably, a reserved opening is formed on the surface of the suspension plate. The reserved opening is a "T"-shaped round opening, and a limiting shaft is inserted into the reserved opening. The limiting shaft is a "T"-shaped cylinder, and the bottom end of the limiting shaft is fixed on the bottom surface of the installation groove.

[0010] Preferably, two jacks I are formed on the surface of the installation groove. Two hand-tightening screws are screwed at one end of the suspension plate away from the limiting shaft. After the suspension plate extends into the installation groove, the bottom end of the hand-tightening screw penetrates through the suspension plate and is inserted into the jack I.

[0011] Preferably, the lapping groove is an arc-shaped groove, and two jacks II are formed on the bottom surface of the lapping groove. After the suspension plate rotates to the lapping groove with the limiting shaft as the central axis, the hand-tightening screw penetrates through the suspension plate and is inserted into the jack II.

[0012] Preferably, a rubber gasket strip is fixed on the surface of the lapping groove, and the rubber gasket strip is clamped between the suspension plate and the lapping groove to generate elastic deformation.

[0013] Preferably, the planting groove is an inverted "convex"-shaped round opening, and a corrugated telescopic enclosure sleeve is fixed inside the planting groove. After being compressed, the corrugated telescopic enclosure sleeve retracts into the planting groove.

[0014] Preferably, two groups of bolt interfaces arranged side by side are formed on the surface of the suspension plate.

[0015] Preferably, two side grooves are formed on both sides of the suspension plate. The side grooves are "U"-shaped grooves, and reinforcing ribs are fixed inside the side grooves.

[0016] A method for using a retaining device for waterfront soil and water conservation ecological restoration includes the following steps: Lay the ditch retaining plate in the intercepting ditch, turn the suspension plate, so that one end of the suspension plate extends into the lapping groove, and then plant green plants in the planting groove. The roots of the green plants are soaked in the water source of the intercepting ditch; The suspension plate acts as a bridge plate spanning the intercepting ditch. When the suspension plate is not needed, turn the suspension plate back into the installation groove for storage.

[0017] Compared with the prior art, the beneficial effects of the present invention are: The retaining device for waterfront soil and water conservation ecological restoration proposed by the present invention and its usage method. By respectively opening splicing grooves at both ends of the ditch retaining plate, the splicing groove is located on the outer ring surface at one end of the ditch retaining plate, and the splicing groove is located on the inner ring surface at the other end. Two ditch retaining plates are misaligned and spliced through the splicing grooves, ensuring seamless assembly of adjacent two ditch retaining plates. This splicing method can effectively prevent soil and water from flowing out at the splicing joints of the ditch retaining plates, enhancing the ability to retain soil and water in the waterfront area.

[0018] An installation groove is opened on the top surface of one side of the ditch retaining plate, and a hanging plate is rotatably connected inside.

They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1, please refer to Figures 1 to 6 The present invention provides a technical solution: a retaining device for ecological restoration of soil and water conservation in waterfront areas, including a ditch retaining plate 1. The two ends of the ditch retaining plate 1 are respectively provided with a splicing groove 101 and a splicing groove 102. The splicing groove 101 is located on the outer ring surface of one end of the ditch retaining plate 1, and the splicing groove 102 is located on the inner ring surface of the other end of the ditch retaining plate 1. The two ditch retaining plates 1 are spliced ​​together in a staggered manner through the splicing groove 101 and the splicing groove 102.

[0024] The end-of-pipe pollution control and reduction technology system for non-point source pollution caused by soil erosion has significant effects on the prevention and control of various pollutants. Although it has little impact on pH value and its interception effect on fluoride and chlorine-containing pollutants is not obvious, it has outstanding effects on the prevention and control of permanganate index, chemical oxygen demand, ammonia nitrogen, total phosphorus, total nitrogen, and nitrate nitrogen, and can effectively reduce the degree of non-point source pollution caused by soil erosion. Constructed wetlands play a primary role in reducing total phosphorus and ammonia nitrogen, and have a good interception effect on phosphorus and nitrogen-containing pollutants, which can reduce the nutrients in water bodies and prevent eutrophication. Ecological purification ponds and ecological interception ditches have significant effects on the degradation of organic pollutants. The former utilizes plant roots and soil filtration, while the latter relies on the joint action of plants and microorganisms. They perform outstandingly in degrading organic pollutants and deepening denitrification, and the three form a complementary organic whole. The ditch retaining plate 1 is a component used to lay the ecological interception ditch. That is, the ditch retaining plate 1 is laid along the ditch, and two adjacent ditch retaining plates 1 are overlapped and spliced ​​by splicing grooves 101 and 102 to ensure seamless splicing of two adjacent ditch retaining plates 1.

[0025] In order to enable the suspended plate 2 to be used as a bridge plate for crossing the ditch retaining plate 1, the following was proposed: On one side of the ditch retaining plate 1, an installation groove 103 is provided on the top surface. Inside the installation groove 103, a suspension plate 2 is rotatably connected. A reserved opening 201 is provided on the surface of the suspension plate 2. The reserved opening 201 is a "T"-shaped circular opening. Inside the reserved opening 201, a limit shaft 202 is inserted. The limit shaft 202 is a "T"-shaped cylinder. The bottom end of the limit shaft 202 is fixed on the bottom surface of the installation groove 103. Two insertion holes one 105 are provided on the surface of the installation groove 103. At one end of the suspension plate 2 away from the limit shaft 202, two hand-tightening screws 6 are screwed. After the suspension plate 2 extends into the installation groove 103, the bottom end of the hand-tightening screw 6 penetrates the suspension plate 2 and is inserted into the insertion hole one 105; the lapping groove 104 is an arc-shaped groove. Two insertion holes two 106 are provided on the bottom surface of the lapping groove 104. After the suspension plate 2 rotates around the limit shaft 202 to the lapping groove 104, the hand-tightening screw 6 penetrates the suspension plate 2 and is inserted into the insertion hole two 106; a rubber gasket strip 5 is fixed on the surface of the lapping groove 104. The rubber gasket strip 5 is clamped between the suspension plate 2 and the lapping groove 104 to generate elastic deformation; two side grooves 203 are provided on both sides of the suspension plate 2. The side grooves 203 are "U"-shaped grooves. Inside the side grooves 203, reinforcing ribs 3 are fixed.

[0026] When the suspension plate 2 is not in use, it is inside the installation groove 1 of the suspension plate 2 is not in use, it is inside the installation groove 103. At this time, the hand-tightening screw 6 penetrates the suspension plate 2 and is inserted into the insertion hole one 105 to brake the suspension plate 2. When using the suspension plate 2, loosen the hand-tightening screw 6 and pull it out of the insertion hole one 105. Then,拨动 the suspension plate 2 to rotate around the limit shaft 202 to the lapping groove 104 until one end of the suspension plate 2 is lapped on the lapping groove 104. At this time, the suspension plate 2 can be stepped on to cross the ditch retaining plate 1. The addition of the reinforcing ribs 3 improves the anti-folding performance of the suspension plate 2.

[0027] In order to plant green plants on the suspension plate 2 and satisfy the roots of the green plants extending into the ditch to strengthen physical filtration and preliminary biodegradation, the following is proposed: On the other side of the ditch retaining plate 1, a lapping groove 104 is provided on the top surface. After the suspension plate 2 rotates, one end of the suspension plate 2 extends into the lapping groove 104. A plurality of planting grooves 204 are provided on the surface of the suspension plate 2; the planting grooves 204 are inverted "convex"-shaped circular openings. Inside the planting grooves 204, corrugated telescopic enclosing sleeves 4 are fixed. After being compressed, the corrugated telescopic enclosing sleeves 4 retract into the planting grooves 204; two groups of side-by-side distributed bolt interfaces 205 are provided on the surface of the suspension plate 2.

[0028] First, screw the hand-tightening screw 6 to fix the end of the suspension plate 2 in the lapping groove 104. Then, stretch the corrugated telescopic enclosing sleeve 4 upward, stuff the green plants into the planting grooves 204, and let the roots of the green plants pass through the planting grooves 204 and extend into the water source of the ditch. Then, fill the corrugated telescopic enclosing sleeve with soil and gently pat the soil to prevent the soil from being too loose and expanding the corrugated telescopic enclosing sleeve 4.

[0029] Embodiment 2 proposes a method for using a retaining device for ecological restoration of water and soil in waterfront areas on the basis of Embodiment 1, including the following steps: Splicing grooves 101 and 102 are respectively formed at both ends of the ditch retaining plate 1. The splicing groove 101 is located on the outer ring surface of one end of the ditch retaining plate 1, and the splicing groove 102 is located on the inner ring surface of the other end of the ditch retaining plate 1. Lay the ditch retaining plate 1 along the ditch, and stagger and overlap and splice adjacent two ditch retaining plates 1 through the splicing grooves 101 and 102 to ensure seamless assembly of adjacent two ditch retaining plates 1.

[0030] When the hanging plate 2 is not in use, it is inside the installation groove 103. At this time, the hand-tightening screw 6 passes through the hanging plate 2 and is inserted into the jack 105 to realize the braking of the hanging plate 2. When it is necessary to use the hanging plate 2 to cross the ditch retaining plate 1, first loosen the hand-tightening screw 6 and pull it out of the jack 105. Make the hanging plate 2 rotate around the limiting shaft 202 to the lap groove 104. The limiting shaft 202 is inserted into the "T"-shaped circular opening reserved opening 201 on the surface of the hanging plate 2, and its bottom end is fixed on the bottom surface of the installation groove 103. Until one end of the hanging plate 2 overlaps the lap groove 104, insert the hand-tightening screw 6 through the hanging plate 2 and insert it into the jack 2 106 at the bottom of the lap groove 104. At this time, the hanging plate 2 can be stepped on to cross the ditch retaining plate 1. A rubber gasket 5 is fixed on the surface of the lap groove 104, and the rubber gasket 5 is clamped between the hanging plate 2 and the lap groove 104 to generate elastic deformation. Two "U"-shaped side grooves 203 are formed on both sides of the hanging plate 2, and a reinforcing rib 3 is fixed inside the side groove 203. The addition of the reinforcing rib 3 improves the anti-folding performance of the hanging plate 2. <\

[0031] Turn the hand-tightening screw 6 to fix the end of the hanging plate 2 in the lap groove 104. Stretch the corrugated telescopic enclosure 4: Stretch the corrugated telescopic enclosure 4 inside the planting groove 204 on the surface of the hanging plate 2 upward. The planting groove 204 is an inverted "convex"-shaped circular opening, and the corrugated telescopic enclosure 4 shrinks into the planting groove 204 after being compressed. Stuff the green plants into the planting groove 204, and pass the roots of the green plants through the planting groove 204 and into the water source of the ditch. Fill the corrugated telescopic enclosure 4 with soil and gently pat the soil to avoid the soil being too loose and expanding the corrugated telescopic enclosure 4. Two groups of side-by-side distribution of bolt interfaces 205 are formed on the surface of the hanging plate 2, which can be used to bolt the foam board. After opening the foam board, lay it on the ditch, and place the green plants in the opening of the foam board.
