Abstract
Description
Technical Field
[0001] The present application relates to the field of riverbank support structures, and particularly to a bank protection pile. In addition, the present application also relates to a bank protection structure. Background Art
[0002] With the development of society, people pay more and more attention to the ecological environment of rivers or water areas. For natural rivers without treatment, after long-term continuous scouring by water flow, the sand, gravel and soil on the riverbank will continuously flow into the river or water area, seriously affecting the functions of the river such as water storage, drainage and water transportation. Moreover, long-term water flow scouring usually erodes the bank foundation of the riverbank. Coupled with the fact that the riverbank is usually overgrown with weeds, once the riverbank collapses, it is extremely easy to cause safety accidents.
[0003] In order to reduce the siltation of sand, gravel and soil in the river and water area and prevent the collapse of the riverbank, it is usually necessary to support the riverbank through a riverbank protection project. The usual support method is to drive support piles along the riverbank. By using the support piles to isolate the water flow and the river embankment, on the one hand, it can prevent the invasion and scouring of the embankment by the water flow and waves, and on the other hand, it can prevent the soil and gravel on the embankment from sliding into the river and water area. Through the support, the safety and stability on both sides of the river can be effectively guaranteed, the self-purification ability of the river can be effectively improved, which is beneficial to the improvement of the water environment, and thus the long-term stability of the water ecosystem can be maintained.
[0004] After the existing support piles are successively driven into the riverbank, there are usually certain gaps between adjacent support piles, and the water flow will still erode the riverbank through the gaps between the support piles. The Chinese utility model patent with the authorization publication number of CN220746881 discloses a precast support pile, and trapezoidal or arc-shaped grooves and tenons are respectively arranged on both sides of the pile body of the support pile to block the water flow from passing through the gaps between the support piles. However, it is very difficult to arrange the support piles closely after they are driven into the riverbank. Once there are gaps between the support piles, there will also be gaps between the grooves and the tenons, and the blocking effect on the water flow is limited. Utility Model Content
[0005] In order to prevent the soil inside the bank protection pile from flowing out from the joints between the bank protection piles and improve the protection effect of the support pile on the riverbank, the present application provides a bank protection pile and a bank protection structure.
[0006] The bank protection pile provided by the present application adopts the following technical solutions:
[0007] A bank protection pile includes a pile body main part and wing plates. The wing plates are integrally connected to both sides of the pile body main part. A first overlapping plate is arranged at the edge of the wing plate on one side of the pile body main part, and a second overlapping plate is arranged at the edge of the wing plate on the other side. The first overlapping plate and the second overlapping plate are respectively arranged on different sides in the thickness direction of the wing plate, and are parallel to the wing plate on the same side. The sides of the first overlapping plate and the second overlapping plate adjacent to the middle of the wing plate are located at the same position in the thickness direction of the wing plate.
[0008] By adopting the above technical solution, by using the first overlapping plate and the second overlapping plate respectively arranged on different sides in the thickness direction of the wing plates on both sides of the pile body main part, when multiple bank protection piles are successively driven into the river bank, the overlapping plates on adjacent bank protection piles can be overlapped alternately to block the contact between the water flow and the river bank and prevent the water flow from scouring the river bank. By using the fact that both the first overlapping plate and the second overlapping plate are parallel to the wing plate on the same side and the sides adjacent to the middle of the wing plate 2 are located at the same position in the thickness direction of the wing plate, reliable overlapping can be achieved with the corresponding sides on adjacent bank protection piles when the bank protection piles are driven along the river bank direction, and water flow can also be blocked from passing through when there are gaps between adjacent bank protection piles.
[0009] In a specific feasible implementation scheme, one side of the pile body main part protrudes outward to form a convex surface, and the other side is recessed inward to form a concave surface. The pile body main part is C-shaped in a cross-section perpendicular to the length direction.
[0010] By adopting the above technical solution, by using the C-shaped structure formed by one side of the pile body main part protruding outward and the other side being recessed inward, a relatively large lateral bearing capacity can be formed with a relatively small mass of the pile body main part, and the supporting strength for the river bank can be improved.
[0011] In a specific feasible implementation scheme, the projection of the convex surface on a plane perpendicular to the pile body main part includes a first straight line, an arc and a second straight line that are successively connected to each other, and both the first straight line and the second straight line are tangent to the arc.
[0012] By adopting the above technical solution, by using the linear structures on both sides of the convex surface in the cross-section, the included angle between both sides of the convex surface and the wing plate can be reduced, the resistance of the convex surface to the water flow in the river channel can be reduced, the influence of the bank protection pile on the river channel water flow can be reduced, and it is beneficial to improve the stability of the bank protection pile.
[0013] In a specific feasible implementation scheme, the arc is an arc with a central angle of 90° - 135°.
[0014] By adopting the above technical solution, by using the arc line with a central angle of 90° - 135°, while forming a sufficient arc top height of the convex surface, the included angle between both sides of the convex surface and the wing plate can be reduced, and the balance between increasing the supporting strength of the bank protection pile and reducing the water flow resistance can be achieved.
[0015] In a specific feasible embodiment, the projection of the concave surface on a plane perpendicular to the pile body is an arc.
[0016] By adopting the above technical solution, with the concave surface in the shape of an arc cylindrical surface, it is possible to reduce the mass of the pile body to a greater extent while increasing the bearing capacity of the revetment pile and the supporting strength for the riverbank to a greater extent.
[0017] In a specific feasible embodiment, the sum of the thicknesses of the first lap plate and the second lap plate is equal to the thickness of the wing plate.
[0018] By adopting the above technical solution, with the sum of the thicknesses of the first lap plate and the second lap plate being equal to the thickness of the wing plate, it can be ensured that the thickness formed after the first lap plate and the second lap plate are lapped is the same as the thickness of the wing plate, guaranteeing that the wing plates of adjacent revetment piles and their lapping areas are flush, and avoiding blocking the water flow and guiding the water flow towards the lap joint.
[0019] In a specific feasible embodiment, the widths and thicknesses of the first lap plate and the second lap plate are equal.
[0020] By adopting the above technical solution, with the widths of the first lap plate and the second lap plate being equal, when the first lap plate and the second lap plate are lapped with each other, each lap plate can be in contact with the wing plate of the adjacent revetment pile, reducing the lap gap therebetween and preventing the water flow from scouring the riverbank to the greatest extent.
[0021] In a specific feasible embodiment, chamfers are provided at the corners of the pile body and the wing plate.
[0022] By adopting the above technical solution, with the chamfers provided at the corners of the pile body and the wing plate, all corners of the revetment pile can have smooth transitions, preventing the corners of the revetment pile from being chipped due to bumps during transportation and construction, which is beneficial to improving the morphological integrity of the revetment pile.
[0023] In a specific feasible embodiment, the wing plates on both sides of the pile body are respectively located on two intersecting planes parallel to the length direction of the pile body.
[0024] By adopting the above technical solution, with the wing plates on both sides of the pile body being located on two intersecting planes, adjacent revetment piles can be lapped with each other on different straight lines, which is beneficial to forming a reliable lap between the lap plates on adjacent wing plates when the revetment piles are driven into a curved riverbank.
[0025] The revetment structure provided by this application includes a plurality of revetment piles provided by this application, and the first overlapping plates, the second overlapping plates, or the first overlapping plate and the second overlapping plate between adjacent revetment piles overlap with each other.
[0026] By adopting the above technical solution, by using the overlapping between the first overlapping plates or the second overlapping plates of adjacent revetment piles, the same side of the main body of adjacent revetment piles can face different directions, which is beneficial to increasing the overall support width of different revetment piles in the revetment structure; by using the overlapping between the first overlapping plate and the second overlapping plate of adjacent revetment piles, the same side of the main body of adjacent revetment piles can face the same direction, which is beneficial to reducing the blockage of the revetment structure to the water flow. These two overlapping situations can be used at riverbanks with different orientations, improving the support effect on riverbanks with different orientations.
[0027] In summary, this application includes at least one of the following beneficial technical effects:
[0028] 1. By using the wing plates provided on both sides of the main body of the pile and the overlapping plates provided on different sides in the thickness direction of the two wing plates, a reliable overlap can be formed with the overlapping plates on the adjacent sides of adjacent revetment piles, which is beneficial to reducing the overlapping gap between the overlapping plates, better blocking the water flow from scouring the riverbank through the overlapping gap, and improving the protection effect on the riverbank.
[0029] 2. By using the fact that the sides of the first overlapping plate and the second overlapping plate adjacent to the middle of the wing plate are parallel to the wing plate and are arranged at the same position in the thickness direction of the wing plate, a reliable contact can be formed between the opposite surfaces of the adjacent overlapping plates of adjacent revetment piles, effectively reducing the overlapping gap between the two. Moreover, when there is a certain arrangement gap between adjacent revetment piles in their arrangement direction, it can ensure that the opposite surfaces of the adjacent overlapping plates remain in close contact, improving the blocking effect on the water flow in the river channel.
[0030] 3. By using the setting that one side of the main body of the pile protrudes outward and the other side is recessed inward, while slightly increasing the mass of the revetment pile, the structural strength of the revetment pile can be effectively improved. On the one hand, it reduces the manufacturing cost of the revetment pile and lightens the transportation burden of the revetment pile, and on the other hand, it enhances the bearing capacity of the revetment pile and improves the protection effect on the riverbank.
[0031] 4. By using the setting that the wing plates on both sides of the revetment pile are arranged on different intersecting planes, when the revetment piles are arranged along the bending direction of the riverbank, a reliable overlap between the overlapping plates of adjacent revetment piles can be ensured. When forming a revetment structure with a zigzag shape along the riverbank, it can effectively block the water flow in the river channel and ensure the support effect for the zigzag riverbank.

Detailed description of the specific implementation mode
[0042] The following will make a detailed description of the specific implementation mode of the present application in conjunction with the accompanying drawings. It should be understood that the specific implementation mode described herein is only used to illustrate and explain the present application, and is not used to limit the present application.
[0043] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "set" and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, and can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.
[0044] In this specification, the terms "first" and "second" are used only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Therefore, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features.
[0045] An embodiment of the revetment pile of the application, as Figures 1 to 3 shown, includes a pile body main body 1 and wing plates 2. The pile body main body 1 and the wing plates 2 are generally integrally processed and formed from reinforced concrete materials. One wing plate 2 is provided on each side of the pile body main body 1, and the two wing plates 2 both extend along the length direction of the pile body main body 1 to both ends of the pile body main body 1, jointly forming an integral revetment pile structure with the pile body main body. When the revetment pile is driven into the river bank for river bank support, the pile body main body 1 and the wing plates 2 are arranged in a direction parallel to the river bank, extending the support range for the river bank.
[0046] On the side edge of the wing plate 2 on one side of the pile body main body 1 away from the pile body main body 1, a first lapping plate 21 is provided. On the side edge of the wing plate 2 on the other side of the pile body main body 1 away from the pile body main body 1, a second lapping plate 22 is provided. The first lapping plate 21 and the second lapping plate 22 both extend along the length direction of the wing plate 2 and cover the entire length direction of the wing plate 2, and the first lapping plate 21 and the second lapping plate 22 are both connected to partial areas in the thickness direction of the wing plate 2, respectively located on different sides in the thickness direction of the wing plate 2. The first lapping plate 21 and the second lapping plate 22 are respectively arranged parallel to the wing plate 2 on the same side. When two revetment piles are successively driven into the river bank, the adjacent first lapping plate 21 and the second lapping plate 22 on the adjacent two revetment piles can Figure 5 and Figure 6 be lapped with each other as shown, forming a flat linear structure extending in the same direction with the adjacent wing plates 2. Moreover, the connection positions in the thickness direction of the side surfaces of the first lapping plate 21 and the second lapping plate 22 located in the middle of the wing plate 2 are the same, enabling the adjacent first lapping plate 21 and the second lapping plate 22 on the adjacent two revetment piles to be closer to each other, preventing water flow from scouring the river bank through the gap between the adjacent two revetment piles and forming a better support effect on the river bank.
[0047] Pile end positioning holes 3 are provided at both ends in the length direction of the revetment pile. Through the pile end positioning holes 3, adjacent two revetment piles can be fixed together using connecting pieces, enabling multiple revetment piles to be connected to each other to form an interconnected integral structure, improving the position stability of the revetment piles driven into the river bank and the overall support strength of the formed revetment structure.
[0048] As Figure 5As shown, an end plate 4 made of metal material can also be provided at the end of the revetment pile. A locking bar hole 41 is provided on the end plate 4 and is arranged opposite to the pile end positioning hole 3. One end of the locking bar hole 41 is a large hole with a larger diameter, and the other end is a small hole with a smaller diameter. The large hole and the small hole are correspondingly connected, and can lock the steel bar inserted into the pile end positioning hole 3.
[0049] In some embodiments of the revetment pile of the present application, such as Figures 1 to 3 As shown, one side surface of the pile body main body 1 bulges outwards to form a convex surface 11, and at the same time, the other side recesses inwards to form a concave surface 12, so that the projection of the pile body main body 1 on the plane perpendicular to the pile body main body 1 is in a C shape, that is, in a C shape in the top view. And the wing plates 2 on both sides of the pile body main body 1 extend linearly outwards from both sides of the pile body main body 1. The surface of the wing plate 2 connected to the convex surface 11 is called the wing plate arch surface 201, and the surface connected to the concave surface 12 is called the wing plate groove surface 202. The C-shaped pile body main body 1 makes the height distance between the convex surface 11 and the wing plate groove surface 202 larger, improving the lateral bearing capacity of the pile body main body 1, so that the pile body main body 1 can withstand greater lateral extrusion force from the river bank. The setting of the concave surface 12 can effectively reduce the mass of the pile body main body 1, while effectively reducing the self-weight of the revetment pile, greatly reducing the material consumption for manufacturing the revetment pile, and reducing the production cost of the revetment pile.
[0050] In a preferred embodiment of the revetment pile of the present application, such as Figure 3 As shown, the projection of the convex surface 11 on the plane perpendicular to the pile body main body 1, that is, the contour line in the top view of the revetment pile, includes a first straight line 111, an arc 112 and a second straight line 113. One end of the first straight line 111 is connected to the contour line of one side wing plate 2. At the same time, the first straight line 111 is tangent to the arc 112, and the two are connected at the tangent point. One end of the second straight line 113 is connected to the contour line of the other side wing plate 2. At the same time, the second straight line 113 is tangent to the arc 112, and the two are connected at the tangent point. The first straight line 111 and the second straight line 113 are symmetrically arranged on both sides of the arc 112, so that the acute angles formed by the first straight line 111 and the second straight line 113 intersecting with the wing plate 2 are equal.
[0051] As Figure 4 shown, the contour line of the convex surface 11 in the top view of the revetment pile can also only include the first straight line 111 and the second straight line 113. One end of the first straight line 111 and the second straight line 113 are respectively connected to the contour lines of the same side wing plate 2, and the other ends are connected to each other to form a convex surface 11 in a folded surface shape. Usually, the included angle between the first straight line 111 and the second straight line 113 is an obtuse angle, while reducing the material used for manufacturing the revetment pile, making the structure of the revetment pile simpler.
[0052] As a specific implementation manner of the revetment pile of the present application, the arc 112 is an arc with a central angle of 90° - 135°, such that the ratio of the protruding height of the convex surface 11 to the straight width of the convex surface 11 is within a reasonable range, while providing sufficient lateral bearing capacity for the pile body main body 1, reducing the resistance when the water flow flows along the wing plate arch surface 201 and the convex surface 11, and improving the comprehensive performance of the revetment pile of the present application for riverbank support. Of course, the central angle of the arc 112 within the range of 0 - 180° is within the acceptable range of the present application. When the central angle of the arc 112 is 0, the convex surface 11 is integrally in a folded surface shape, and when the wing plates 2 on both sides of the pile body main body 1 are in the same plane and the central angle of the arc 112 is 180°, the convex surface 11 is integrally in a semi-cylindrical surface shape.
[0053] In some embodiments of the revetment pile of the present application, as Figure 3 shown, the projection of the concave surface 12 on the plane perpendicular to the pile body main body 1, that is, the contour line in the top view of the revetment pile, is an arc. At this time, the concave surface 12 is an arc cylindrical surface, and such a setting can, while ensuring the mechanical strength of the pile body main body 1, greatly reduce the mass of the pile body main body 1.
[0054] In some embodiments of the revetment pile of the present application, as Figures 1 to 3 shown, the sum of the thickness of the first lap joint plate 21 and the thickness of the second lap joint plate 22 is equal to the thickness of the wing plate 2. In this way, when two revetment piles are successively driven into the riverbank for riverbank support, as Figure 5 and Figure 6 shown, the first lap joint plate 21 and the second lap joint plate 22 on the adjacent revetment pile overlap with each other, and the thickness of the overlapping part of the first lap joint plate 21 and the second lap joint plate 22 is the same as the thickness of the wing plate 2, forming a balanced support force for the riverbank and having a relatively small impact on the water flow in the river channel.
[0055] In a preferred embodiment of the revetment pile of the present application, as Figure 3 shown, the width of the first lap joint plate 21 is equal to the width of the second lap joint plate 22, and the thickness of the first lap joint plate 21 is also equal to the thickness of the second lap joint plate 22.
[0056] As Figure 5 and Figure 6 shown, when the adjacent two revetment piles overlap with each other, the same width of the first lap joint plate 21 and the second lap joint plate 22 can make relatively small gaps be formed between the free ends of the first lap joint plate 21 and the second lap joint plate 22 and the opposite wing plate 2, which is beneficial to preventing the scouring of the riverbank formed by the water flow passing through the gap between the adjacent two revetment piles. And the setting that the thicknesses of the first lap joint plate 21 and the second lap joint plate 22 are equal can, when the adjacent two revetment piles are as Figure 9When the reverse lap joint shown is used, reliable lap joints can also be achieved between the two first lap plates 21 and the two second lap plates 22. This not only makes the lap gaps between the two first lap plates 21 and between the two second lap plates 22 smaller, but also enables the thicknesses of the lap portions of the two first lap plates 21 and the two second lap plates 22 to be closer to the thickness of the wing plate 2.
[0057] In some embodiments of the revetment pile of the present application, as Figures 1 to 3 shown, at each corner of the pile body main body 1, at each corner of the wing plates 2 on both sides of the pile body main body 1 including the first lap plates 21 and the second lap plates 22 connected thereto, and at the corners where the pile body main body 1 is connected to the wing plates 2, chamfers are provided, and the chamfers at each corner are generally arc-shaped chamfers. The provision of the chamfers can prevent damage to the corners of the revetment pile when it is bumped during transportation and construction.
[0058] In some other embodiments of the revetment pile of the present application, as Figure 7 shown, the wing plates 2 on both sides of the pile body main body 1 extend in different directions away from the pile body main body 1, so that the wing plates 2 on both sides of the pile body main body 1 are respectively located on two intersecting planes parallel to the length direction of the pile body main body 1. At this time, an included angle θ is formed between the wing plates 2 on both sides of the pile body main body 1. Such a revetment pile can be used at the curved position of the river bank, so that while adjacent revetment piles extend along the curved direction of the river bank, a good lap state can be ensured between the lap plates of adjacent revetment piles. Specifically, the size of the included angle θ between the wing plates 2 on both sides of the pile body main body 1 can be determined according to the actual curved direction and curved angle of the river bank. The value of θ can be greater than 180° or less than 180°, but for the convenience of processing the revetment pile, θ is usually less than 180°. For the curved situation of the river bank greater than 180°, it can be achieved by arranging the revetment piles in reverse.
[0059] An embodiment of the revetment structure of the present application, as Figure 8 and Figure 9 shown, is formed by arranging a plurality of revetment piles of any embodiment of the present application in sequence along the river bank. When the revetment pile is driven into the river bank, the pile body main body 1 and the wing plates 2 on both sides thereof are arranged along the trend of the river bank. According to the actual situation of the river bank, different embodiments of the revetment piles of the present application can be selected and combined with each other. The revetment pile can be driven into the river bank with the concave surface 12 facing the river bank, or with the convex surface 11 facing the river bank. When adjacent revetment piles are arranged in the same direction as Figure 8 shown, the first lap plate 21 on one side of the revetment pile overlaps with the second lap plate 22 of the adjacent revetment pile; when adjacent revetment piles are arranged in the same direction as Figure 9When arranged in the reverse order as shown, the first overlapping plate 21 on one revetment pile overlaps with the first overlapping plate 21 on the adjacent revetment pile, and the second overlapping plate 22 on the revetment pile overlaps with the second overlapping plate 22 on the adjacent revetment pile.
