Description

Technical Field

[0001] This invention relates to the field of highway slope protection technology, and in particular to a phosphogypsum ecological slope stabilization technology and its application. Background Technology

[0002] Phosphogypsum is a solid waste generated during the production of phosphate fertilizers and phosphoric acid. Currently, the resource utilization of phosphogypsum is not very satisfactory. Existing technologies have used phosphogypsum for slope protection, such as Patent Document 1, which discloses a novel method for preventing seepage into phosphogypsum reservoir slopes. This method uses phosphogypsum for slope protection and lays a layer of HDPE membrane on top of the phosphogypsum to prevent water from seeping into the phosphogypsum and polluting the environment. Although this slope protection uses phosphogypsum to protect the slope, it is complex in structure and has a long construction period because it requires laying an HDPE membrane and separately constructing drainage structures to prevent water seepage. Furthermore, since slopes are not flat, they deteriorate over time. The soil layers above will experience some slippage, potentially causing the laid HDPE to fail due to tensile tearing. For example, Patent Document 2 discloses a composite ecological slope protection block. During slope protection, it uses a snap-fit ​​interlocking structure to connect the blocks, filling the spaces between them with soil, and then planting vegetation. The steps formed by the blocks mitigate rainwater erosion from the top to the bottom of the slope, effectively controlling soil erosion. The vegetation also creates an aesthetically pleasing landscape, protecting the riverbank's ecological environment. However, this type of protection structure... While the structure can mitigate the erosion of rainwater from the top to the bottom of the slope, it also hinders the smooth retention of rainwater. The rainwater stored within the steps formed by the blocks increases in weight over time. Combined with the flow of water and soil on the slope, this eventually leads to significant stress between the blocks, causing the interlocking connections between them to loosen and ultimately fail. Finally, as disclosed in Patent Document 3, a landscape design for a green protective slope includes several drainage channels 2 on the slope's solidification layer 1 and several "V"-shaped structures on the soil layer 7. The water trough 13 is divided into a drainage trough 14. The above-mentioned water trough structure guides the water on the solidified layer 1 to be discharged. However, the drainage structure does not take into account the problem that the slope will shift over time. As the slope shifts, the drainage trough may become blocked. At the same time, the above-mentioned water trough structures will not change after they are set up. They cannot actively form an adaptive drainage trough structure according to the slope shift or the amount of rainwater. Therefore, its drainage effect needs to be improved and the service life of the drainage structure needs to be increased.

[0006] In summary, existing technologies for slope protection, while using phosphogypsum, primarily focus on preventing water penetration into the phosphogypsum layer. Drainage is often limited to simple fixed drainage channels dug into the slope, without considering the potential for slope shift over time or due to external forces. This shift not only damages the laid HDPE membrane but also causes misalignment or drainage problems between drainage channels. Therefore, this invention provides a phosphogypsum-based ecological slope stabilization technology and its application, featuring a drainage channel structure that actively selects drainage channels for slope protection. Summary of the Invention

[0007] To overcome the shortcomings of existing phosphogypsum ecological slope stabilization methods, this invention provides a technical solution: a phosphogypsum ecological slope stabilization structure, comprising: a slope, a phosphogypsum layer, a waterproof brick layer, and a slope body. The slope is located on one side of the slope body, the phosphogypsum layer covers the slope, and the waterproof brick layer is disposed on and covers the phosphogypsum layer. The waterproof brick layer is composed of several waterproof bricks, and each waterproof brick is provided with a water-guiding channel. The waterproof brick layer prevents water from seeping into the phosphogypsum layer, and allows water to be guided from the slope body to the ground through the water-guiding channel. Each waterproof brick includes a brick body and a water-guiding plate rotatably disposed on the brick body, with the water-guiding channel disposed on the water-guiding plate. The water guiding channel includes a main water channel, a left arc-shaped water guiding channel, and a right arc-shaped water guiding channel. The left and right arc-shaped water guiding channels are connected to the main water channel, and the main water channel, the left arc-shaped water guiding channel, and the right arc-shaped water guiding channel are in a "V" shape. The water guiding plate is rotatably mounted on the brick body via rotating shafts A and B. In two adjacent waterproof bricks, the main water channel of the lower waterproof brick is opposite to the left or right arc-shaped water guiding channel of the upper one. When water flows through the waterproof brick layer, the water guiding plate can rotate to adapt to the water flow, thereby automatically selecting whether the water flows through the left or right arc-shaped water guiding channel. After the water guiding channels on each waterproof brick are connected, a water guiding channel is formed for the water flow.

[0008] Preferably, the rotating shaft A and rotating shaft B are respectively disposed at both ends of the water guide plate, and the axes of rotating shaft A and rotating shaft B coincide. The main water channel is a semi-circular arc channel structure, and the axis of the main water channel is parallel to the axis of rotating shaft B. Moreover, when viewed from a direction perpendicular to the front of the water guide plate, the axis of the main water channel coincides with the axis of rotating shaft B. The brick body is a hollow frame structure.

[0009] Preferably, the four side walls of the brick are respectively provided with two inner spherical cores and two outer spherical buckles. The inner spherical core includes an inner tube and a spherical shell one, and the outer spherical buckle includes an outer tube and a spherical shell two. When each waterproof brick is locked in place, the spherical shell two is locked on the outside of the spherical shell one, and the inner tube and outer tube are respectively fixed to the side wall of the brick, and the inner tube and outer tube are connected to the inner side of the brick.

[0010] Preferably, it also includes an arc-shaped frame, which comprises a U-shaped frame body, an HDPE membrane, and dovetail groove connectors. The U-shaped frame body is a metal frame structure made of steel or iron sheet. The HDPE membrane is attached to the inner side of the U-shaped frame body. Two dovetail groove connectors are provided, located on the top two sides of the U-shaped frame body respectively. The waterproof brick layer is fixed to the slope on all four sides by upper edge connecting structures, lower edge connecting structures, left edge connecting structures, and right edge connecting structures. The upper edge connecting structure includes a snap-fit ​​strip located on the top side of the slope that mates with the dovetail groove of the dovetail groove connector, and an arc-shaped frame. The upper side wall of the top waterproof brick is provided with a snap-fit ​​block that mates with the dovetail groove connector. The left edge connecting structure includes a left edge connecting rod and an arc-shaped frame. The left edge connecting rod is equipped with a snap-fit ​​block that engages with a dovetail groove connecting buckle. The left side wall of the waterproof brick on the left side is also equipped with a snap-fit ​​block that engages with a dovetail groove connecting buckle. The right edge connecting structure includes a right edge connecting rod and an arc-shaped frame. The right edge connecting rod is equipped with a snap-fit ​​block that engages with a dovetail groove connecting buckle. The right side wall of the waterproof brick on the right side is also equipped with a snap-fit ​​block that engages with a dovetail groove connecting buckle. The lower edge connecting structure includes a lower edge connecting rod and an arc-shaped frame. The lower edge connecting rod is equipped with a snap-fit ​​block that engages with a dovetail groove connecting buckle. The lower side wall of the lower layer of waterproof brick is also equipped with a snap-fit ​​block that engages with a dovetail groove connecting buckle.

[0011] Preferably, the system further includes a connecting rod that passes through the U-shaped frame and is threaded. From left to right, the connecting rod is threaded with a first limiting sleeve, a second limiting sleeve, a third limiting sleeve, and a fourth limiting sleeve. The first and second limiting sleeves are engaged at one end of the U-shaped frame, and the third and fourth limiting sleeves are engaged at the other end. The U-shaped frame can slide along the connecting rod. One end of the connecting rod is fixed to a waterproof brick, and the other end is fixed to a slope, the left edge of the connecting rod, the bottom edge of the connecting rod, or the right edge of the connecting rod.

[0012] Preferably, the arc-shaped frame includes a connecting rod one and a connecting rod two, and a connecting sleeve 50 is provided between the connecting rod one and the connecting rod two. When the waterproof brick moves, the U-shaped frame can adaptably deform. Moreover, since the U-shaped frame has a certain elasticity, it can also actively adjust the position of the waterproof brick. When the deformation is too large, the U-shaped frame will abut against the limiting sleeve, thereby ensuring the connection strength of the arc-shaped frame.

[0013] Preferably, an arc-shaped frame is provided between each waterproof brick, and a connecting block that engages with the dovetail groove connecting buckle is provided on the side wall of the brick, so that the HDPE membrane is in a flat state and no longer adheres to the inner side wall of the U-shaped frame. The two ends of the HDPE membrane are respectively fixed to the two ends of the U-shaped frame, so that the HDPE membrane also forms a flat surface like the waterproof brick.

[0014] Preferably, both the inner and outer pipes are located at the bottom of the side wall of the brick, so that water entering the brick can also flow out through the channel formed by the inner and outer pipes.

[0015] Preferably, in order to facilitate the smooth flow of water between adjacent waterproof bricks in the upper and lower layers, water guiding channels are also provided on the bricks at positions corresponding to the main water channel, the left arc-shaped water guiding channel, and the right arc-shaped water guiding channel, so as to facilitate the smooth flow of water.

[0016] The beneficial effects of this invention are as follows:

[0017] 1) The phosphogypsum ecological slope stabilization technology of the present invention uses phosphogypsum in slope protection. Considering that the slope will shift after a long time, a waterproof and water-conducting layer made of several waterproof bricks is laid on the phosphogypsum layer during slope protection. The waterproof bricks are provided with water flow channels that can dynamically change to adapt to the amount of water flow. So no matter how the slope shifts in the direction of the vertical slope, a water flow channel that can adapt to the size and amount of water flow can be adaptively adjusted. Compared with the existing fixed water flow channels, it can achieve better water guiding effect.

[0018] 2) The phosphogypsum ecological slope stabilization technology of the present invention, in order to adapt to the displacement of the slope in the direction parallel to the slope surface, sets a fixed vertical rod on each side of the slope. The waterproof bricks connected to the fixed vertical rods are detachably connected to the fixed vertical rods through an HDPE membrane. Through this setting, the waterproof bricks can adapt to the displacement of the slope, and even if the waterproof bricks are displaced, there will be no water seepage. The HDPE membrane is set between the two waterproof bricks through an arc-shaped frame. The arc-shaped frame has a certain elasticity and can adaptively adjust the distance between the two waterproof bricks, so that the distance between the waterproof bricks can be actively adjusted when the slope is displaced.

[0019] 3) Furthermore, the waterproof bricks are arranged in a cross pattern, which makes the connection between the waterproof bricks more secure. The upper end of the waterproof brick includes a movable water guide plate, which is rotatably set on the upper end of the waterproof brick. The water guide plate can adapt to the amount of water flowing through both ends and adjust which channel the water passes through. In this way, it can adapt to the deformation of rainwater and slope and automatically select the channel that allows more water to flow, thus changing the problem of difficult water diversion on the slope.

[0020] 4) Furthermore, the upper surface of the water guide plate is provided with a herringbone-shaped water guide channel. The water guide plate is rotatably mounted on the waterproof brick via a rotating shaft, and the rotating shaft passes through the central axis of symmetry of the herringbone shape. Thus, when water passes through the water guide channel, if more water passes through a certain channel in the herringbone shape, the water will tilt towards the channel with more water, and the water will choose to be guided through that channel. Finally, the water guide channels with water passing through each water guide plate are connected in series to form a complete water guide channel structure. This allows the water guide channel structure to be automatically selected according to the direction of water flow. Compared with the existing fixed water guide channel structure, it can automatically form a water guide channel structure by adapting to rainwater and slope deformation, and can achieve a better water guiding effect.

[0021] 5) Preferably, in order to keep the water guide plate as horizontal as possible in the initial state and to enable it to automatically select the water channel according to the size of the water flow, a weighted pendulum is set below the water guide plate. This ensures that no matter how the slope is deformed, the water guide plate is always level with respect to the axis of symmetry of the "V" shape, thus ensuring that the water channel of the water guide plate is automatically selected according to the water flow.

The water guide plate 12 is rotatably arranged on the brick body 11 through a rotating shaft A16 and a rotating shaft B17. Among two adjacent waterproof bricks up and down, the main water guide groove 13 of the waterproof brick at the lower end is opposite to the position of the left arc water guide groove 14 or the right arc water guide groove 15 of the upper end. When water flows through the waterproof brick layer 3, the water guide plate 12 can rotate to adapt to the water flow, so as to automatically select the water flow to pass through the left arc water guide groove 14 or the right arc water guide groove 15. After the water guide grooves 10 on each waterproof brick 9 are connected, a water guide channel for the water flow to pass through is formed.

[0031] Preferably, as Figure 3 shown, the rotating shaft A16 and the rotating shaft B17 are respectively arranged at both ends of the water guide plate 12, and the axes of the rotating shaft A16 and the rotating shaft B17 coincide. The main water guide groove 13 is a semi-circular arc groove structure.

[0032] Preferably, in order to facilitate the fixation of each waterproof brick 9, two inner ball cores 33 and two outer ball buckles 34 are respectively arranged on the four side walls of the brick body 11. As Figure 4 shown, the inner ball core 33 includes an inner tube body 35 and a first ball shell 36, and the outer ball buckle 34 includes an outer tube body 38 and a second ball shell 37. When each waterproof brick 9 is clamped and fixed, the second ball shell 37 is clamped outside the first ball shell 36. The inner tube body 35 and the outer tube body 38 are respectively fixed on the side wall of the brick body 11, and the inner tube body 35 and the outer tube body 38 are connected to the inside of the brick body 11.

[0033] Preferably, as Figure 1-2As shown in Figure 5, in order to securely lay the waterproof brick layer 3 on the phosphogypsum layer 2, an arc-shaped frame 39 is also included. The arc-shaped frame 39 includes a U-shaped frame body 41, an HDPE film 40, and dovetail groove connecting buckles 42. The U-shaped frame body 41 is a metal frame structure, and its material can be steel, iron sheet, etc. The HDPE film is attached to the inner side of the U-shaped frame body 41. Two dovetail groove connecting buckles 42 are provided, located on the top two sides of the U-shaped frame body 41 respectively. The waterproof brick layer 3 is fixed to the slope 1 on all four sides by the upper edge connecting structure 5, the lower edge connecting structure 6, the left edge connecting structure 7, and the right edge connecting structure 8. The upper edge connecting structure 5 includes a snap-fit ​​strip set on the top side of the slope 4 that mates with the dovetail groove of the dovetail groove connecting buckle 42, and the arc-shaped frame 39. The upper side wall of the top waterproof brick 9 is provided with a dovetail groove. The left edge connecting structure 7 includes a left edge connecting rod 52 and an arc-shaped frame 39. The left edge connecting rod 52 is provided with a snap-fit ​​block that mates with the dovetail groove connecting buckle 42. The left side wall of the waterproof brick 9 on the left side is provided with a snap-fit ​​block that mates with the dovetail groove connecting buckle 42. The right edge connecting structure 8 includes a right edge connecting rod 53 and an arc-shaped frame 39. The right edge connecting rod 53 is provided with a snap-fit ​​block that mates with the dovetail groove connecting buckle 42. The right side wall of the waterproof brick 9 on the right side is provided with a snap-fit ​​block that mates with the dovetail groove connecting buckle 42. The lower edge connecting structure 6 includes a lower edge connecting rod 51 and an arc-shaped frame 39. The lower edge connecting rod 51 is provided with a snap-fit ​​block that mates with the dovetail groove connecting buckle 42.

[0034] Preferably, such as Figure 6 As shown, in order to ensure that the arc-shaped frame 39 can adapt to the displacement between the waterproof bricks 9 caused by the deformation of the slope, a connecting rod 43 is also included. The connecting rod 43 passes through the U-shaped frame 41 and is threaded. The connecting rod 43 is threaded with a first limiting sleeve 44, a second limiting sleeve 45, a third limiting sleeve 46, and a fourth limiting sleeve 47 from left to right. The first limiting sleeve 44 and the second limiting sleeve 45 are engaged at one end of the U-shaped frame 41, and the third limiting sleeve 46 and the fourth limiting sleeve 47 are engaged at the other end of the U-shaped frame 41.

One end of the connecting rod 43 is fixedly set on the waterproof brick 9, and the other end is fixedly set on the slope 4, the left edge connecting rod 52, the lower edge connecting rod 51, or the right edge connecting rod 53.

[0035] Preferably, such as Figure 6As shown in (B), to facilitate the fixing of the connecting rods between the waterproof brick and the slope 4, the left edge connecting rod 52, the lower edge connecting rod 51, or the right edge connecting rod 53, the arc frame 39 includes a first connecting rod 48 and a second connecting rod 49, and a connecting sleeve 50 is provided between the first connecting rod 48 and the second connecting rod 49. This arrangement makes the length between the first connecting rod 48 and the second connecting rod 49 adjustable, thus making the connection more convenient. The U-shaped frame 41 can adaptably deform when the waterproof brick 9 moves, and because the U-shaped frame 41 has a certain elasticity, it can also actively adjust the position of the waterproof brick 9. When the deformation is too large, the U-shaped frame 41 will abut against the limiting sleeve, thereby ensuring the connection strength of the arc frame 39.

The two ends of the HDPE film are respectively fixed to the two ends of the U-shaped frame 41. In this way, the HDPE film also forms a flat surface like the waterproof bricks 9.

[0037] Preferably, to ensure the smooth drainage of water flowing into the brick body 11, an inner pipe 35 and an outer pipe 38 are provided at the bottom of each side wall of the brick body 11, allowing water entering the brick body 11 to flow out through the channel formed by the inner pipe 35 and the outer pipe 38.

[0038] Preferably, in order to facilitate the smooth flow of water between the two adjacent waterproof bricks 9, water guiding structures are also provided on the brick body 11 at positions corresponding to the main water channel 13, the left arc-shaped water guiding channel 14 and the right arc-shaped water guiding channel 15, so that water can be guided smoothly.

[0039] Preferably, in order to prevent the water guide plate 12 from swinging continuously, or to ensure that the water guide plate 12 is in a horizontal state, a counterweight is provided at the lower part of the water guide plate 12 at the central axis position. This can prevent the water guide plate 12 from malfunctioning and also prevent the water guide plate 12 from moving due to slight slippage of the slope.

[0040] Preferably, the waterproof brick 9 is made of impermeable concrete, which includes silicate cement, fly ash, river sand, rock particles with a particle size greater than 5 mm, and water-reducing agent; the elastic membrane is a membrane structure with a certain degree of elasticity, and its material can be polyurethane or rubber.

The phosphogypsum ecological slope-fixing structure according to claim 3, characterized in that: It also includes a connecting rod (43), which passes through the U-shaped frame (41) and is threaded. The connecting rod (43) is threaded with a first limiting sleeve (44), a second limiting sleeve (45), a third limiting sleeve (46) and a fourth limiting sleeve (47) from left to right. The first limiting sleeve (44) and the second limiting sleeve (45) are locked at one end of the U-shaped frame (41), and the third limiting sleeve (46) and the fourth limiting sleeve (47) are locked at the other end of the U-shaped frame (41). The U-shaped frame (41) can slide along the connecting rod (43). One end of the connecting rod (43) is fixedly set on the waterproof brick (9), and the other end is fixedly set on the slope (4), the left edge connecting rod (52), the lower edge connecting rod (51) or the right edge connecting rod (53).

5. The phosphogypsum ecological slope-fixation structure according to claim 4, characterized in that: The arc frame (39) includes a first connecting rod (48) and a second connecting rod (49), and a connecting sleeve (50) is provided between the first connecting rod (48) and the second connecting rod (49). The U-shaped frame (41) can adaptably deform when the waterproof brick (9) moves. Moreover, since the U-shaped frame (41) has a certain elasticity, it can also actively adjust the position of the waterproof brick (9). When the deformation is too large, the U-shaped frame (41) will abut against the limiting sleeve, thereby ensuring the connection strength of the arc frame (39).

6. The phosphogypsum ecological slope stabilization structure as described in claim 5, characterized in that: An arc-shaped frame (39) is provided between each waterproof brick (9). The side wall of the brick body (11) is provided with a connecting block that cooperates with the dovetail groove connecting buckle (42), so that the HDPE membrane is in a flat state and no longer adheres to the inner side wall of the U-shaped frame (41). The two ends of the HDPE membrane are respectively fixed to the two ends of the U-shaped frame (41). In this way, the HDPE membrane also forms a flat surface like the waterproof brick (9).

7. The phosphogypsum ecological slope stabilization structure as described in claim 6, characterized in that: An inner pipe (35) and an outer pipe (38) are provided at the bottom of the side wall of the brick body (11), so that water entering the brick body (11) can also flow out through the channel formed by the inner pipe (35) and the outer pipe (38).

8. The phosphogypsum ecological slope stabilization structure as described in claim 6, characterized in that: In order to facilitate the smooth flow of water between the two adjacent waterproof bricks (9), water guiding structures are also provided on the brick body (11) at the positions corresponding to the main water channel (13), the left arc-shaped water guiding channel (14) and the right arc-shaped water guiding channel (15), so that water can be guided smoothly.
