Description

Technical Field

[0001] This invention relates to the field of river protection technology, and in particular to a green and ecological river slope sheet pile support structure. Background Technology

[0002] Green and ecological riverbank sheet pile support structures are a river management technology that integrates stability and ecological restoration. They primarily utilize materials such as ecological U-shaped sheet piles, plastic-steel sheet piles, or composite steel sheet piles. Through scientific layout and construction, they stabilize riverbanks, prevent soil erosion, and create conditions for vegetation restoration and ecological reconstruction. These structures typically possess high strength and corrosion resistance, and achieve rapid assembly construction through prefabricated components and specialized connection designs, minimizing disturbance to the water area.

[0003] For example, patent document CN215518834U discloses a cofferdam device for hydraulic construction that is easy to assemble, including an outer baffle. Two adjacent outer baffles are slidably connected to each other through a first trapezoidal limiting block and a first trapezoidal limiting groove, thereby facilitating the assembly and disassembly of the outer enclosure. However, since the height of the outer enclosure is usually fixed, this type of cofferdam device makes it difficult to observe the water surface at low water levels and fails to meet the water-blocking requirements at high water levels. Summary of the Invention

[0004] Therefore, it is necessary to provide a green and ecological riverbank slope sheet pile support structure to address the technical problems of current cofferdam devices having fixed heights that make it inconvenient to observe water surface conditions or fail to meet the requirements for water blocking.

[0005] The above objectives are achieved through the following technical solutions: A green and ecological riverbank slope sheet pile support structure includes sheet piles and floating plates. The sheet piles are hollow and multiple in number. The length of the sheet piles extends vertically, and the width of the sheet piles extends horizontally. The multiple sheet piles are connected sequentially in the horizontal direction, and adjacent sheet piles are detachably connected by dovetail joints. The floating plates are multiple in number, and each floating plate is slidably mounted on its respective sheet pile in the vertical direction. The floating plates on adjacent sheet piles are interlocked. Each floating plate has a blocking surface extending vertically. Thus, when the water level in the river changes, the multiple floating plates can move up and down synchronously relative to their respective sheet piles, so that the blocking surface and the outer surface of the sheet pile can jointly block the water in the river.

[0006] Furthermore, the sheet pile is provided with an inlet and an outlet, which are located on both sides of the sheet pile along its width, and multiple inlets and outlets are distributed along the vertical direction. The inlet is used to allow water from the river to enter the interior of the sheet pile, and the outlet is used to allow water from the interior of the sheet pile to flow out. Both the inlet and outlet are provided with elastic filter screens, which can block large particles of impurities from entering the interior of the sheet pile. The bottom of the sheet pile is provided with filler material, which is used to purify the river water. The filler material is made of shrimp shells or squid bones.

[0007] Furthermore, each floating plate is equipped with an insert, which is slidably disposed inside each sheet pile. The insert includes a suction and drainage plate, which is inclined relative to the vertical direction, so that when the floating plate moves up and down, it can drive the insert to move synchronously, thereby allowing the suction and drainage plate to slide synchronously up and down inside the sheet pile. The suction and drainage plate draws water from the outside of the sheet pile into the inside of the sheet pile through the inlet and discharges water from the inside of the sheet pile to the outside through the outlet.

[0008] Furthermore, the insert also includes multiple filter frames and multiple connecting blocks. The multiple filter frames are distributed in the vertical direction, and adjacent filter frames are snapped together by connecting blocks. Each connecting block is provided with two hinge shafts extending in the horizontal direction, and the axis of the hinge shafts is perpendicular to the width direction of the sheet pile. The water suction and drainage plate is hinged to the connecting block through the hinge shafts. Two water suction and drainage plates on the same connecting block are symmetrically arranged about the vertical axis. In the initial state, the two water suction and drainage plates on the same connecting block maintain a fixed included angle.

[0009] Furthermore, an adjusting rod is detachably connected to the floating plate. The adjusting rod extends in the vertical direction and can be slidably inserted into the interior of multiple connecting blocks at the same time. The vertical movement of the adjusting rod can synchronously adjust the two symmetrically arranged suction and drainage plates, so that the two suction and drainage plates can rotate freely around their respective hinge axes at a certain angle.

[0010] Furthermore, the connecting block is provided with a through hole extending in the vertical direction, and the adjusting rod can slide up and down along the through hole. Multiple adjusting ring grooves are distributed along the length direction of the adjusting rod. The adjusting ring grooves are coaxially arranged with the adjusting rod. The end of the suction and drainage plate is provided with a hinge ring, which is hinged to the hinge shaft. The outer circumferential surface of the hinge ring is provided with an anti-rotation plane. When the anti-rotation plane is opposite to the adjusting ring groove on the adjusting rod, the hinge ring can rotate freely around the hinge shaft at a certain angle.

[0011] Furthermore, the filter frame has a hollow structure and a three-layer structure, consisting of a filter plate, a filter mesh layer, and an adsorption layer from the outside to the inside. The filter plate has a first filter hole with its axis extending horizontally. The filter mesh layer is fitted to the inner wall of the filter plate, and the adsorption layer is fitted to the side of the filter mesh layer away from the filter plate. The adsorption layer is used to purify river water and is made of shrimp shell or squid bone material.

[0012] Furthermore, the sheet pile has a horizontal partition inside, which seals the filler at the bottom of the sheet pile. The horizontal partition has a second filter hole with its axis extending vertically. The lower surface of the horizontal partition has a filter membrane that can purify the river water.

[0013] Furthermore, in the width direction of the sheet pile, one end of the floating plate is provided with a snap-fit ​​groove, and the other end is provided with a snap-fit ​​protrusion. The snap-fit ​​protrusion can seamlessly connect with the snap-fit ​​groove of the adjacent floating plate.

[0014] Furthermore, the lower end of the sheet pile is pointed, and the pointed end is used to insert into the soil layer of the riverbank slope.

[0015] The beneficial effects of this invention are: This invention provides a green and ecological riverbank slope sheet pile support structure. First, a floating plate is installed on the sheet pile. When the water level is low, the floating plate can move downward relative to the sheet pile, so that the floating plate will not obstruct personnel from observing the water surface. When the water level is high, the floating plate can automatically move upward relative to the sheet pile, so that the blocking surface of the floating plate and the outer surface of the sheet pile can jointly block the water in the river, increase the water blocking range, and improve the adaptability of the green and ecological riverbank slope sheet pile support structure to water level changes.

[0016] Secondly, because the suction and drainage plates can move up and down synchronously with the floating plate, the upward-moving suction and drainage plates create negative pressure inside the sheet pile. This draws river water through the inlet, while large particles of impurities in the river water are blocked by the elastic filter screen. The filtered river water then enters the interior of the sheet pile and is finally guided by the downward-moving suction and drainage plates to the bottom of the sheet pile and discharged through the outlet. This improves purification efficiency.

[0017] Third, when the water level in the river fluctuates significantly (i.e., when the waves are large), the two suction and drainage plates on the same connecting block maintain a fixed angle, which facilitates the suction and drainage plates to move up and down with the floating plate, thereby sucking up and discharging river water and improving purification efficiency. When the water level in the river fluctuates less (i.e., when the waves are small), the two suction and drainage plates can be freely rotated around their respective hinge axes by adjusting the rod. In this way, under the action of gravity, the two suction and drainage plates will gradually move closer to the filter frame, which facilitates the sedimentation of small particles of impurities inside the sheet pile and improves the river water purification effect.

[0018] Fourth, the filler at the bottom of the sheet piles and the adsorption layer of the filter frame are both made of shrimp shells or squid bones, which can adsorb heavy metal ions, organic pollutants, pigments, etc. in the water, reducing the concentration of pollutants in the river and improving the water quality. At the same time, shrimp shells or squid bones are widely available, environmentally friendly and biodegradable, and will not cause secondary pollution to the river's ecological environment, which is in line with the concept of green ecology.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0024] like Figures 1 to 9 As shown in the figure, an embodiment of the present invention provides a green and ecological riverbank slope sheet pile support structure, including sheet piles 104 and floating plates 102. The sheet piles 104 are hollow structures and are provided in multiples. The length of the sheet piles 104 extends in the vertical direction. The multiple sheet piles 104 are connected sequentially in the horizontal direction, and adjacent sheet piles 104 are detachably connected by dovetail joints. The floating plates 102 are provided in multiples, and each floating plate 102 is slidably disposed on each sheet pile 104 in the vertical direction. The floating plates 102 on adjacent sheet piles 104 are snapped together. Each floating plate 102 has a blocking surface extending in the vertical direction. Thus, when the water level in the river changes, the multiple floating plates 102 can move up and down synchronously relative to their respective sheet piles 104, so that the blocking surface and the outer surface of the sheet piles 104 can jointly block the water in the river.

[0025] The sheet piles 104 employ a hollow structure, reducing their weight while maintaining sufficient strength, thus facilitating transportation and construction. Multiple sheet piles 104 are detachably connected horizontally via dovetail joints. This dovetail connection ensures a tight fit between the sheet piles 104, forming a continuous, integrated structure. This enhances the overall integrity and anti-slip capability of the support structure, effectively blocking lateral pressure from the riverbank slope and preventing slope collapse. It also improves construction efficiency and shortens the construction period. The floating plate 102 is internally filled with foam material 112, which is made of polyethylene foam, ensuring that the floating plate 102 can float on the water surface.

[0026] A floating plate 102 is installed on the sheet pile 104. When the water level is low, the floating plate 102 can move downward relative to the sheet pile 104, so that the floating plate 102 will not obstruct personnel from observing the water surface. When the water level is high, the floating plate 102 can automatically move upward relative to the sheet pile 104, so that the blocking surface of the floating plate 102 and the outer surface of the sheet pile 104 can jointly block the water in the river channel, increase the water blocking range, and thus improve the adaptability of the green ecological river slope sheet pile support structure to water level changes.

[0027] Furthermore, the sheet pile 104 is provided with an inlet 116 and an outlet 117, which are located on both sides of the sheet pile 104 along its width, and multiple inlets and outlets are distributed along the vertical direction. The inlet 116 is used to allow water from the river to enter the interior of the sheet pile 104, and the outlet 117 is used to allow water from the interior of the sheet pile 104 to flow out. Both the inlet 116 and the outlet 117 are provided with elastic filter screens 103, which can block large particles of impurities from entering the interior of the sheet pile 104. The bottom of the sheet pile 104 is provided with filler material 109, which is used to purify the river water. The filler material 109 is made of shrimp shells or squid bones. Since the direction of water flow in the river remains unchanged, the river water can only enter through the inlet 116 and flow out through the outlet 117.

[0028] A vertical plate is detachably installed on the sheet pile 104, and the liquid inlet 116 and liquid outlet 117 are set on the vertical plate.

[0029] The filler 109 at the bottom of the sheet pile 104 is made of shrimp shell or squid bone material. It utilizes the porous structure of squid bone and the chitin properties of shrimp shell, and enhances mechanical properties through high-temperature sintering or bio-solidification. At the same time, it retains the natural porosity of the material, which can adsorb, filter and decompose pollutants in the river water, thereby purifying the river water, helping to improve the river water quality and enhance the quality of the river's ecological environment.

[0030] Furthermore, each float plate 102 is provided with an insert, which is slidably disposed inside each sheet pile 104. The insert includes a suction and drainage plate 105, which is inclined relative to the vertical direction, so that when the float plate 102 moves up and down, it can drive the insert to move synchronously, thereby making the suction and drainage plate 105 slide synchronously up and down inside the sheet pile 104. The suction and drainage plate 105 draws water from the outside of the sheet pile 104 into the inside of the sheet pile 104 through the inlet 116, and discharges water from the inside of the sheet pile 104 to the outside through the outlet 117.

[0031] Because the suction and drainage plate 105 can move up and down synchronously with the float 102, the upward-moving suction and drainage plate 105 creates a negative pressure inside the sheet pile 104, thereby drawing river water through the inlet 116. Large particles of impurities in the river water are blocked by the elastic filter screen 103, allowing the filtered river water to enter the interior of the sheet pile 104 and finally be guided by the downward-moving suction and drainage plate 105 to the inner bottom of the sheet pile 104 and discharged through the outlet 117. This accelerates the entry of water from the river into the sheet pile 104 through the inlet 116 and accelerates the flow of water from the sheet pile 104 out of the outlet 117, improving purification efficiency. At the same time, during the suction or discharge process, the elastic filter screen 103 will undergo elastic deformation, which can prevent large particles of impurities from adhering to its surface, thereby preventing the elastic filter screen 103 from easily becoming clogged.

[0032] Furthermore, the insert also includes multiple filter frames 108 and multiple connecting blocks 106. The filter frames 108 are distributed vertically, and adjacent filter frames 108 are engaged with each other via connecting blocks 106. Each connecting block 106 is provided with two horizontally extending hinge shafts 107, and the axis of the hinge shafts 107 is perpendicular to the width direction of the sheet pile 104. The water suction and drainage plate 105 is hinged to the connecting block 106 via the hinge shafts 107. Two water suction and drainage plates 105 on the same connecting block 106 are symmetrically arranged about the vertical axis. In the initial state, the two water suction and drainage plates 105 on the same connecting block 106 maintain a fixed included angle. The filter frames 108 and the connecting blocks 106 are detachably connected by dovetail joints, which facilitates assembly and disassembly.

[0033] The two suction and drainage plates 105 maintain a fixed angle, which allows the two suction and drainage plates 105 to better suck up and discharge river water.

[0034] Furthermore, an adjusting rod 101 is detachably connected to the float 102. The adjusting rod 101 extends vertically and can be simultaneously slidably inserted into the interior of multiple connecting blocks 106. The vertical movement of the adjusting rod 101 can synchronously adjust the two symmetrically arranged suction and drainage plates 105, allowing each of the two suction and drainage plates 105 to rotate freely around its respective hinge axis 107 at a certain angle. The adjusting rod 101 is threadedly connected to the float 102.

[0035] When the water level in the river changes significantly (i.e., when the waves are large), the two suction and drainage plates 105 on the same connecting block 106 maintain a fixed angle, which facilitates the suction and drainage plates 105 to move up and down with the float 102, thereby sucking up and discharging river water and improving purification efficiency. When the water level in the river changes less significantly (i.e., when the waves are small), the two suction and drainage plates 105 can be freely rotated around their respective hinge axes 107 by adjusting the rod 101. In this way, under the action of gravity, the two suction and drainage plates 105 will gradually move closer to the filter frame 108, which facilitates the sedimentation of small particulate impurities inside the sheet pile 104 and improves the river water purification effect.

[0036] Furthermore, the connecting block 106 is provided with a through hole extending in the vertical direction, and the adjusting rod 101 can slide up and down along the through hole. Multiple adjusting ring grooves 1011 are distributed along the length direction of the adjusting rod 101. The adjusting ring grooves 1011 are coaxially arranged with the adjusting rod 101. The end of the suction and drainage plate 105 is provided with a hinge ring, which is hinged to the hinge shaft 107. The outer circumferential surface of the hinge ring is provided with an anti-rotation plane 1051. When the anti-rotation plane 1051 is opposite to the adjusting ring groove 1011 on the adjusting rod 101, the hinge ring can rotate freely around the hinge shaft 107 at a certain angle.

[0037] This design is simple and makes it easy to adjust the angle of the water suction and drainage plate 105.

[0038] Furthermore, the filter frame 108 has a hollow structure and a three-layer structure, which consists of a filter plate 113, a filter mesh layer 114, and an adsorption layer 115 from the outside to the inside. The filter plate 113 is provided with a first filter hole, the axis of which extends horizontally. The filter mesh layer 114 is fitted to the inner wall of the filter plate 113. The adsorption layer 115 is fitted to the side of the filter mesh layer 114 away from the filter plate 113. The adsorption layer 115 is used to purify river water and is made of shrimp shell or squid bone material.

[0039] The first filter holes and filter screen layer 114 on the filter plate 113 can prevent small particulate impurities (such as suspended particles and algae) in the river water from entering the interior of the filter frame 108, thereby promoting the settling and sedimentation of small particulate impurities. The adsorption layer 115 can adsorb heavy metal ions, organic pollutants, pigments, etc. in the water, reducing the concentration of pollutants in the river water and improving the water quality. At the same time, shrimp shells or squid bones are widely available, environmentally friendly and biodegradable, and will not cause secondary pollution to the river's ecological environment, which is in line with the concept of green ecology.

[0040] Furthermore, the sheet pile 104 is provided with a horizontal partition 111 inside, which seals the filler 109 in the inner bottom of the sheet pile 104. The horizontal partition 111 is provided with a second filter hole, the axis of which extends in the vertical direction. The lower surface of the horizontal partition 111 is provided with a filter membrane 110, which can purify the river water.

[0041] The second filter holes extending vertically on the baffle can intercept medium-sized impurities (such as fine silt and aquatic plant remains) in the water that are not blocked by the filter screen at the inlet 116, preventing these impurities from directly contacting the filler 109, reducing the risk of clogging the pores of the filler 109, and extending the service life of the filler 109; the filter membrane 110 on the lower surface of the horizontal baffle 111 can perform more refined treatment on the river water passing through the second filter holes, and can intercept tiny suspended particles, some colloidal substances, and even microorganisms (such as algal spores) in the water, making the river water entering the area of ​​the filler 109 cleaner, allowing the filler 109 to focus more on adsorbing small molecule pollutants such as heavy metal ions and organic pollutants, avoiding impurities from interfering with the adsorption process, and significantly improving the overall purification efficiency.

[0042] Furthermore, in the width direction of the sheet pile 104, one end of the floating plate 102 is provided with a snap-fit ​​groove, and the other end is provided with a snap-fit ​​protrusion. The snap-fit ​​protrusion can seamlessly connect with the snap-fit ​​groove of the adjacent floating plate 102.

[0043] This design allows multiple floating panels 102 to move up and down synchronously, while also blocking river water.

[0044] Furthermore, the lower end of the sheet pile 104 is pointed, and the pointed end is used to insert into the soil layer of the riverbank slope, and the pointed end is triangular.

[0045] Based on the above embodiments, the usage principle and working process of the embodiments of the present invention are as follows: Multiple sheet piles 104 are interconnected and inserted into the soil layer of the riverbank slope. Initially, the two suction and drainage plates 105 on the same connecting block 106 maintain a fixed angle. When the water level in the river changes significantly (i.e., when the waves are large), the float 102 moves up and down with the water level. Since the suction and drainage plates 105 can move up and down synchronously with the float 102, the upward-moving suction and drainage plates 105 will create a negative pressure inside the sheet pile 104, thereby drawing river water through the inlet 116. Large particles of impurities in the river water are blocked by the elastic filter screen 103, and the filtered river water enters the interior of the sheet pile 104. Finally, it is guided by the downward-moving suction and drainage plates 105 to the inner bottom of the sheet pile 104 and discharged through the outlet 117.

[0046] Due to the three-layer structure of the filter frame 108 and the filler 109 at the bottom of the sheet pile 104, the river water entering the sheet pile 104 can be purified, improving purification efficiency and effect. During the process of pumping or discharging river water, the elastic filter screen 103 will undergo elastic deformation, which can prevent large particles of impurities from adhering to its surface, thereby preventing the elastic filter screen 103 from clogging easily.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
