Description

Technical Field

[0001] This utility model relates to the field of construction, and in particular to water conservancy engineering construction technology, specifically a multifunctional ecological revetment block for river regulation. Background Technology

[0002] Ecological revetment blocks, as an alternative to traditional rigid revetments, have become the mainstream choice for modern riverbank management while ensuring the stability and safety of the riverbank and taking into account ecological restoration and landscape functions. However, existing ecological revetment block technologies often employ planar splicing, pin connections, or rope linkages, which have significant drawbacks: First, the overall connection is poor, with blocks relying solely on friction or weak mechanical connections to resist loads. Under conditions of uneven foundation settlement, soil erosion, or severe water scouring, local instability or even overall collapse can easily occur. Second, the connectors are mostly made of metal or plastic, which can lead to electrochemical corrosion or aging rate mismatches with the concrete block body, affecting the long-term durability of the structure. Third, construction is complex, often requiring special hoisting tools or complicated alignment procedures, resulting in low efficiency.

[0003] Therefore, there is an urgent need for a new type of ecological revetment block system that has sufficient connection rigidity, good integrity, convenient construction, environmental friendliness, and can fundamentally prevent revetment collapse. Utility Model Content

[0004] The purpose of this utility model is to provide a multifunctional ecological revetment block for river regulation. The block adopts a biomimetic Chinese traditional woodworking "wedge nail tenon" structure, sets standardized connection interfaces on the four sides of the block, and uses back-through wedge nails of the same material for locking and anchoring, thereby achieving strong lateral interlocking force between the blocks and reliable vertical anchoring between the revetment and the foundation, forming an ultra-stable integrated revetment structure.

[0005] To achieve the above objectives, this utility model provides a multifunctional ecological revetment block for river channel improvement, comprising a block body and wedges. The block body is a regular square prism structure, with all four sides having identical structures. Each side is provided with a pair of protruding tenons, a pair of concave mortises matching the shape of the tenons, and a half-hole formed in the adjacent surfaces of the tenons and mortises. The tenons and mortises are arranged alternately. The arrangement of the tenons and mortises ensures that when any side of two adjacent block bodies is aligned... When the blocks are joined together, the tenon of the first block body can be inserted into the mortise of the second block body, and the half-holes of the first and second blocks body can be aligned to form a complete, vertically penetrating wedge hole; the wedge is a frustum-shaped rod, the cross-sectional shape of the wedge matches the wedge hole, the length of the wedge is greater than the height of the block body, and the lower end of the wedge is a conical tip for driving into the foundation; the wedge is configured to be driven into the wedge hole after the blocks are joined to lock adjacent blocks and anchor them into the foundation.

[0006] Furthermore, this utility model provides a multifunctional ecological revetment block for river channel improvement, wherein the cross-section of the tenon and the mortise is trapezoidal.

[0007] Furthermore, this utility model provides a multifunctional ecological revetment block for river channel improvement, wherein the block body is provided with ecological holes penetrating the upper and lower end faces.

[0008] Furthermore, this utility model provides a multifunctional ecological revetment block for river channel improvement, wherein the top surface of the block body is provided with a planting trough or a water-friendly step surface.

[0009] Furthermore, this utility model provides a multifunctional ecological revetment block for river channel improvement, wherein the top of the wedge is provided with an enlarged nail head.

[0010] Furthermore, this utility model provides a multifunctional ecological revetment block for river regulation, wherein the block body and the wedges are both made of fiber-reinforced concrete or recycled aggregate concrete.

[0011] Furthermore, this utility model provides a multifunctional ecological revetment block for river channel improvement, wherein the wedges are driven into the foundation to a depth of not less than 300mm.

[0012] The multifunctional ecological revetment block for river regulation provided by this utility model has the following advantages compared with the existing technology:

[0013] 1. This utility model innovatively applies the "wedge tenon" principle to revetment engineering. The post-insertion wedges actively apply compressive force to the blocks through their wedge effect, achieving a strong rigid connection between the blocks and transforming the dispersed blocks into a cohesive whole. At the same time, the wedges penetrate deep into the foundation, providing excellent pull-out and shear resistance, forming a composite stability mechanism of "lateral locking and vertical anchoring", which fundamentally eliminates the risk of revetment collapse.

[0014] 2. The four sides of the blocks are completely identical, enabling "non-directional" assembly, much like Lego bricks. This greatly reduces the difficulty of construction and alignment requirements, and improves paving efficiency. Workers only need to assemble the blocks and then nail them in place. The process is clear and the quality is controllable.

[0015] 3. The wedges and the main block are made of the same inorganic material, which completely avoids the problem of electrochemical corrosion. The structure is safe and reliable throughout its entire life cycle and does not cause any pollution to the environment.

[0016] 4. When it is necessary to replace a single block, the relevant wedges can be pulled out for replacement, which is reversible. Attached Figure Description

[0024] like Figures 1-3 As shown in the figure, this embodiment provides a multifunctional ecological revetment block for river channel improvement, which includes a block body 1 and wedges 2. The block body 1 is a regular square prism structure. The block body 1 has ecological holes 3 penetrating through the upper and lower end faces for filling soil to plant aquatic plants or provide habitat passages for aquatic animals. The top surface of the block body 1 is provided with a planting trough or a water-friendly step surface to enhance its ecological and landscape functions. The four sides of the block body 1 have identical structures. Each side is provided with a pair of protruding tenons 4, a pair of concave mortises 5 that match the shape of the tenons 4, and a half-hole formed in the adjacent face of the tenons 4 and mortises 5. The tenons 4 and mortises 5 are arranged alternately. The cross-section of the tenons 4 and mortises 5 is trapezoidal, and the self-locking property of the trapezoid enhances the stability after interlocking. The arrangement of the tenon 4 and the mortise 5 ensures that when any side of two adjacent masonry blocks 1 are spliced ​​together, the tenon 4 of the first masonry block 1 can be inserted into the mortise 5 of the second masonry block 1, and the half-holes of the first and second masonry blocks 1 can be aligned to form a complete, vertically penetrating wedge hole 6; the wedge 2 is a frustum-shaped rod, the top of the wedge 2 is provided with an enlarged nail head 7, which facilitates hammering and can cover the hole opening, the cross-sectional shape of the wedge 2 matches the wedge hole 6, the length of the wedge 2 is greater than the height of the masonry block 1, and the lower end of the wedge 2 is a conical tip 8 for driving into the foundation; the wedge 2 is configured to be driven into the wedge hole 6 after the masonry blocks are spliced ​​to lock adjacent masonry blocks and anchor them into the foundation, and the depth of the wedge 2 driven into the foundation is not less than 300mm;

[0025] As a preferred embodiment, both the block body 1 and the wedge 2 are made of fiber-reinforced concrete or recycled aggregate concrete, which completely avoids the problem of electrochemical corrosion, ensures the safety and reliability of the structure throughout its entire life cycle, and causes no pollution to the environment.

[0026] During construction, the sides of two masonry blocks 1 are brought close together, so that the tenon 4 of the first masonry block 1 is inserted into the mortise 5 of the second masonry block 1. At this time, the half-hole on the tenon 4 and the half-hole in the mortise 5 are precisely aligned, forming a complete circular wedge hole 6. The conical tip 8 of the wedge 2 is aligned with the wedge hole 6, and it is driven vertically in with a rubber hammer or other machinery. During the downward movement of the wedge 2, its conical surface presses against the inner wall of the wedge hole 6, generating huge radial pressure, which firmly locks the two masonry blocks 1 in the horizontal direction, making them inseparable. At the same time, the conical tip 8 of the wedge 2 penetrates the base layer and penetrates into the stable soil layer of the foundation, providing a strong vertical anchoring force. By repeating the above steps and splicing all the masonry blocks and driving in a sufficient number of wedges 2, an extremely stable, eco-friendly and beautiful revetment structure can be formed.
