Description

Technical Field

[0001] The utility model relates to the field of water conservancy building blocks and ecological landscape, in particular to a chain-type ecological slope protection brick and a chain-type ecological slope protection brick assembly. Background Art

[0002] At present, conventional interlocking ecological slope protection bricks generally adopt a partially locked structural design. For example, the patented technology with application number "202321159008.3": an inclined hole interlocking ecological slope protection brick. When this type of brick is laid on a slope, the protruding part of the edge of the brick is embedded in the interlocking notch of another adjacent brick. After embedding, the bricks form a whole piece on the slope surface, and the structural strength is good. However, this technology has the following defects:

[0003] Due to weather reasons (such as cold climate, etc.), the bricks will experience ice expansion (mostly occurs in the north). Once ice expansion occurs, since the bricks are tightly fitted together, only a small relative displacement can occur between the bricks. Therefore, during the ice expansion, the bricks may be damaged. Since the ice expansion occurs many times and repeatedly, the bricks are more likely to be damaged.

[0004] Based on this, it is necessary to develop a chain-type ecological slope protection brick and a chain-type ecological slope protection brick assembly to overcome the above technical problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a chain-type ecological slope protection brick and a chain-type ecological slope protection brick assembly, which effectively overcomes the defects of the prior art.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, an angle α is formed between the slope surface and the main body, and 105°≤α≤120°.

[0010] Furthermore, the cross-sectional shape of the above-mentioned engaging portion is an isosceles trapezoid.

[0014] The beneficial effects are: the structural design is simple and reasonable, the bricks can be effectively interlocked and laid to form a whole surface, and at the same time, the design of the first slope surface can enable the bricks to move relatively and expand along the first slope surface when frost expansion occurs in cold weather, effectively relieving the frost expansion force and avoiding damage to the bricks and the overall paving.

[0025] The principles and features of the present utility model will be described below in conjunction with the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0026] Example: As Figure 1 and 2 shown, the interlocking ecological slope protection brick of this embodiment includes a brick body 1 in the shape of "I". The above brick body 1 includes a rectangular main body part 11. At both ends of the above main body part 11 near the ends, fitting parts 12 are respectively vertically and symmetrically extended toward both sides. One side of the two above fitting parts 12 on the same side that is close to each other is set as a first inclined plane, and an isosceles trapezoidal interlocking notch 13 is formed between the two above fitting parts 12 on the same side and the main body part 11.

[0027] The interlocking ecological slope protection brick of this embodiment adopts a special structural design. The brick body 1 is integrally designed in the shape of "I", and fitting parts 12 that are axially symmetrically distributed are respectively formed on both sides of both ends of the main body part 11. The inner side of the fitting part 12 is set as a first inclined plane. When the brick body 1 and the brick body 1 are assembled and fitted, one fitting part 12 of two same brick bodies 1 will be embedded in one interlocking notch 13, that is, the fitting parts 12 of the brick body 1 and the brick body 1 will be in side-end contact (that is, the two first inclined planes will be in contact with each other). In this way, when ice expansion occurs, the first inclined planes of two adjacent brick bodies 1 can relatively slide, realizing the separation of the brick bodies, effectively releasing the ice expansion force, and avoiding damage to the whole.

[0028] In this embodiment, an included angle α is formed between the above inclined plane and the main body part 11, and 105° ≤ α ≤ 120°.

[0029] In this embodiment, the shape of the interlocking ecological slope protection brick has at least the following two structural designs:

[0030] 1) The cross-sectional shape of the above fitting part 12 is an isosceles trapezoid, that is, both the inner and outer sides of each fitting part 12 are designed as first inclined planes.

[0031] 2) The cross-sectional shape of the above fitting part 12 is a right trapezoid, that is, only the inner side of each fitting part 12 is designed as a first inclined plane.

[0032] In this embodiment, the above-mentioned interlocking ecological slope protection bricks are cast and formed with concrete having a grade above C40 and a frost resistance grade above F300, which can solve the problem of freeze-thaw damage of concrete. After casting, the thickness of the brick body 1 is between 12 cm and 20 cm, which can be adjusted according to different use environments. Of course, the above grades are only the preferred solutions of this embodiment. During the actual construction and production process, the concrete grade and frost resistance grade can be adjusted under the condition of conforming to relevant national or industrial specifications, or can be adjusted according to the requirements of the project owner unit or the design unit under the condition of conforming to the specifications.

[0033] As a preferred implementation manner, a first through hole 111 penetrating through both ends thereof is provided in the main body portion 11, and second through holes 112 penetrating through the corresponding ends and passing through the two fitting portions 12 are respectively provided in the inner parts of both ends of the main body portion 11, and two third through holes 113 penetrating through both sides thereof are provided at intervals in the middle area of the main body portion 11.

[0034] In the above-mentioned implementation scheme, the design of the first through hole 111 and the second through hole 112 can, on the one hand, achieve the purpose of weight reduction, and on the other hand, flexible connecting members can be respectively inserted into the first through hole 111 and the second through hole 112 to longitudinally and horizontally connect multiple interlocking and spliced brick bodies 1, so as to improve the structural strength after paving.

[0035] Embodiment 2

[0036] As shown in Figure 2 , the interlocking ecological slope protection brick combination of this embodiment includes multiple interlocking ecological slope protection bricks in Embodiment 1. The multiple interlocking ecological slope protection bricks are arranged in multiple rows. A contraction gap (designated by L in the figure) is formed between the ends of the main body portions 11 of two adjacent interlocking ecological slope protection bricks in each row. The two fitting portions 12 at the mutually approaching ends of two adjacent interlocking ecological slope protection bricks in each row extend into the interlocking notch 13 of one of the interlocking ecological slope protection bricks in the adjacent row, and among the three, the first inclined surfaces of the fitting portions 12 of two adjacent rows of interlocking ecological slope protection bricks are mutually attached, and a hollow ecological hole 201 is formed among the three.

[0037] In this interlocking ecological slope protection brick combination, the fitting portions 12 at the mutually approaching ends of two interlocking ecological slope protection bricks in the same row are embedded into the interlocking notch 13 of one interlocking ecological slope protection brick in the adjacent row, and the first inclined surfaces inside the fitting portions 12 are mutually attached. And after paving, a contraction gap will be formed between two adjacent interlocking ecological slope protection bricks in the same row. The contraction gap, in cooperation with the design of the first inclined surface (the first inclined surfaces are mutually attached), enables the brick bodies 1 to relatively slide and expand when the brick bodies 1 undergo ice expansion in cold seasons or weather, effectively releasing the ice expansion force and reducing breakage.

[0038] In this embodiment, the area ratio of the ecological holes 201 in the assembly is about 12% (that is, the porosity accounts for 12% of the area of the entire assembly), and the landscape beautification effect can be achieved by optimizing the size adjustment as needed.

[0039] As a preferred implementation manner, the first through holes 111 of multiple adjacent above-mentioned interlocking ecological slope protection bricks in the same row are penetrated, and a first connecting wire rope is threaded through them.

[0040] In the above-mentioned implementation scheme, the first through holes 111 in the same row are axially penetrated, and a first connecting wire rope is threaded through them, so that the brick bodies 1 in the same row are strung together by the first connecting wire rope, improving the connection strength between them.

[0041] As a preferred implementation manner, the two above-mentioned third through holes 113 of a single above-mentioned interlocking ecological slope protection brick respectively penetrate through the second through holes 112 at both ends of the above-mentioned interlocking ecological slope protection bricks in the adjacent row in a one-to-one correspondence, and second connecting wire ropes are respectively threaded through them.

[0042] In the above-mentioned implementation scheme, after the brick bodies 1 are laid, the second through holes 112 of the brick bodies 1 in two adjacent rows are penetrated and strung together by the threaded second connecting wire ropes. Cooperating with the series connection of the first connecting wire rope, the entire assembly is interconnected in the longitudinal and transverse directions by the first connecting wire rope and the second connecting wire rope, with better integrity and better interlocking strength after laying.

[0043] In this embodiment, the above-mentioned first connecting wire rope and second connecting wire rope are both steel stranded wires. Since the steel stranded wire itself has a certain toughness and a certain shrinkage performance, when the brick bodies 1 expand due to ice and slide and push each other apart, the steel stranded wire can pull the rope to a certain extent. After the ice expansion ends and returns to normal, the steel stranded wire can recover its own shrinkage and drive the brick bodies 1 in the assembly to return to their positions to a certain extent.

[0044] Of course, in this embodiment, the first connecting wire rope and the second connecting wire rope include but are not limited to steel stranded wires, high-galvanized steel wires, steel bars, etc.
