Description

Technical Field

[0001] The utility model relates to the technical field of bank protection structures, in particular to an assembled bank protection. Background Art

[0002] The main function of revetments is to protect against waves and currents and maintain shoreline stability. Traditional slope revetments are primarily riprap slope revetments, constructed along the shoreline using materials such as boulders and bagged sand. They are protected by structures such as large boulders, twisted king-shaped blocks, four-legged hollow blocks, and fence panels. These structures require numerous construction steps, are labor-intensive, and technically complex. The bond between the embankment and the shore foundation is insufficient, and under the long-term effects of wind and waves, uneven local forces cannot be effectively and evenly distributed to the embankment and the shore foundation behind it, requiring the shore foundation to provide stability. This can lead to revetment slippage and collapse of sections of the embankment structure. Furthermore, the slope of these revetments is generally shallow, resulting in a larger foundation footprint. Traditional vertical revetments, on the other hand, primarily utilize structures such as concrete blocks, sheet piles, caissons, buttresses, and inserted cylinders. Because the support force is provided solely by the limited foundation at the bottom, they place high demands on the foundation's bearing capacity. Utility Model Content

[0003] The purpose of the present invention is to overcome the defects in the prior art and provide an assembled revetment to overcome one or more problems caused by the limitations and defects of the relevant technology to a certain extent.

[0004] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0005] A prefabricated revetment comprises a plurality of embankment blocks and a bottom protection block spliced along the shoreline. The embankment blocks are cast as one piece and are a structure with a hollow interior and transparent and open upper and lower ends. The structure comprises a guard panel facing the sea survey, a retaining plate on the shore side, a footing structure and a cross pile structure. One end of the footing structure is connected to the guard panel and the other end is against the bottom protection. The guard panel is arranged at an angle, the retaining plate is arranged vertically, and a cross pile structure is arranged in the middle of the retaining plate. The backfill area between the retaining plate and the original shore edge is filled with backfill material. The cross pile structure is inserted in the backfill material to provide horizontal anchoring connection force. The cross pile structure comprises a ground-grabbing vertical plate and a plurality of connecting cross plates. The ground-grabbing vertical plate is arranged vertically, and a plurality of connecting cross plates are arranged vertically and distributed in parallel and equidistantly. One end of the cross pile structure is connected to the middle of the ground-grabbing vertical plate and the other end is connected to the retaining plate.

[0006] Alternatively, after the embankment blocks are filled with fillers, a continuous wave-blocking wall is cast in situ at the upper ends of the embankment blocks.

[0007] Alternatively, after the embankment block is filled with filler, a wave-breaking wall is assembled at the upper end of the embankment block. The wave-breaking wall is formed by splicing and assembling the end faces of several wave-breaking blocks. The wave-breaking block includes integrated panels on both sides, an internal frame structure and an upper sealing plate at the top.

[0008] Furthermore, the joints of the wave-blocking blocks and the joints of the embankment blocks below are offset from each other.

[0009] Furthermore, the inclination angle of the guard plate is 45°-75°.

[0010] Compared with the existing technology, the assembled revetment of the utility model has the following beneficial effects:

[0011] The revetment is formed by assembling the embankment blocks to form the embankment body and the face protection. The support frame, the face protection panel and the retaining wall with the middle support are integrally formed on the embankment block. The structure is light and easy to hoist and assemble, and the overall stress performance is good. The face protection panel will not fall off. The core of the embankment is formed by the internal filler, and the overall wind and wave resistance is high. Under the conditions of sufficient grip and stability maintenance, a larger face protection slope can be allowed. In addition, the retaining wall is provided with a horizontal pile structure to improve the bonding strength between the embankment block and the backfill material, provide horizontal anchoring force, limit and constrain the embankment block in the horizontal direction, and share the stress of the foundation.

[0015] The following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only the best embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0016] This embodiment provides an assembled revetment, such as Figure 1-Figure 2As shown, the revetment is formed by a number of embankment blocks 5 spliced along the coastline to form the embankment body and the protective surface. The embankment block 5 is cast in one piece, and is formed by a support frame 52 of a frame structure connecting and supporting a protective panel 51 and a retaining plate 54. The protective panel 51 is arranged on the sea side, and the retaining plate 54 is arranged on the sea side. The lower ends of the protective panel 51 and the retaining plate 54 can form pile feet 53 to be inserted into the foundation for preliminary stability, and the embankment block 5 has a hollow structure with open upper and lower ends. The internal hollow structure is filled with filler 8 to form an embankment core. After the filler 8 is filled, not only the self-weight of the embankment block 5 is increased, but also the combination effect of the filler 8 with the bottom foundation is better than that of the filler 8. The artificial blocks are better and more stable. In addition, most of the structure of the support frame 52 can be buried in the embankment core filler 8, which increases the contact area between the embankment block 5 and the core filler 8, evenly transfers the wind and wave intensity of the embankment to the embankment core filler 8, evenly bears the force on the whole, and fully utilizes the friction of the foundation. Therefore, the slope of the sloped revetment in the prior art for placing the artificial blocks of the surface is 1:1.25-1:2.0, that is, the slope angle is 27°-39°, while the inclination angle of the integrated guard plate 51 on the embankment block 5, that is, the revetment slope can be designed to be 45°-75°, which can significantly reduce the area occupied by the bottom foundation.

[0017] The retaining plate 54 is generally arranged vertically to reduce the pressure of the backfill soil at the rear. The revetment is assembled at a certain distance from the bank, and there is a backfill area 2 between the retaining plate 54 and the bank. In order to prevent the embankment block 5 from becoming unstable during the backfilling and compaction rolling process, a horizontal pile structure 7 is integrally formed on the retaining plate 54. The horizontal pile structure 7 is the same length as the retaining plate 54, and includes a ground-gripping vertical plate 72 and a plurality of connecting horizontal plates 71. The ground-gripping vertical plate 72 is arranged parallel to the retaining plate 54, and is connected to the middle part of the retaining plate 54 by a plurality of vertically arranged and parallel and equidistantly distributed connecting horizontal plates 71. When backfilling, the backfill height after compaction is at least 1 meter higher than the upper end of the horizontal pile structure 7. The horizontal pile structure 7 can provide horizontal anchoring force, limit and constrain the embankment block 5 in the horizontal direction, and share the force of the foundation, which can reduce the influence of foundation settlement to a certain extent.

[0018] In order to better stabilize the embankment block 5, a foot guard structure 4 is integrally formed on the seaward side of the guard panel 51. The foot guard structure 4 is also a frame structure with a hollow interior and open top and bottom. It is combined with the bottom guard 3 for reinforcement. The foot guard structure 4 is the same length as the embankment block 5. Its outer panel is vertically arranged and abuts against the end of the bottom guard 3 layer paved with blocks. The interior of the foot guard structure 4 is filled with filler 8.

[0019] According to the water level design, after filling the filler 8 in the embankment block 5, a continuous wave-blocking wall 7 can be built and cast in situ on the upper end of the embankment block 5. In order to prevent debris from accumulating inside the embankment block 5, the wave-blocking wall 7 should close the opening at the upper end of the embankment block 5;

[0020] Of course, the wave-breaking block 61 can also be prefabricated for on-site assembly. The upper end of the embankment block 5 can be made into an inward-recessed embedding area, and the lower end of the wave-breaking block 61 is plugged and connected to the embedding area, and the connection between the two is reinforced by a connecting component, and the assembly gap between the two is sealed with concrete. The wave-breaking block 61 also adopts a structural form of integrated panels on both sides and internal frame support. The integrated panel can be an inclined plate or a straight plate, and the top of the wave-breaking block 61 needs to be integrally formed with an upper sealing plate 62; during assembly, the splicing seams of the wave-breaking block 61 and the splicing seams of the embankment block 5 below should be staggered with each other to improve the overall structural strength; compared with the cast-in-place wave-breaking wall 7, the prefabricated wave-breaking block 61 assembled wave-breaking wall 7 is easier to prefabricate the lightweight wave-breaking block 61 in the factory, which is conducive to reducing the overall weight of the bank protection, and has a short construction period and low assembly technical difficulty.
