Technical Field
[0001] This utility model relates to the field of bank protection technology, specifically a block and bank protection. Background Technology
[0002] In water conservancy projects, such as the treatment of river, lake, and shore slopes, revetments are commonly used for slope management and protection. Revetments typically consist of masonry blocks, which are stacked layer by layer from the bottom up to form a retaining wall along the slope. Current technologies generally involve combining various types of blocks to create revetments of different shapes or requirements, leading to complex production and construction processes and hindering cost reduction and efficiency improvement. The applicant aims to research a type of masonry block that can be used for laying various types of revetments. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and propose a block that is conducive to the laying of various revetments, thereby simplifying production and construction; it also proposes a revetment that uses the aforementioned block.
[0004] Compared with the prior art, this utility model proposes a block, including a precast block body. The precast block body includes an inwardly inclined water-facing surface, a vertically arranged back surface, a top surface, and a bottom surface. The top surface is horizontally arranged and has a trapezoidal protrusion on the side near the back surface. The lower side of the inner waist side of the trapezoidal protrusion connects with the upper side of the back surface. The trapezoidal protrusion extends along the axial direction of the precast block body. The bottom surface is horizontally arranged and has a trapezoidal groove in the middle. The trapezoidal groove extends along the axial direction of the precast block body. The cross-section of the trapezoidal protrusion is the same as the cross-section of the trapezoidal groove. When the blocks are stacked, the trapezoidal groove and the trapezoidal protrusion cooperate to make the stacked blocks staggered front and back. The trapezoidal protrusion and the trapezoidal groove can slide relative to each other along the axial direction of the precast block body.
[0005] In some embodiments, two inverted trapezoidal protrusions with the same structure are provided on both sides of the trapezoidal groove. The inverted trapezoidal protrusions extend along the axial direction of the precast block body, and the cross-section of the inverted trapezoidal protrusions is the same as the cross-section obtained by inverting the trapezoidal protrusions.
[0006] In some embodiments, the width of the top side surface is formed by the bottom width of the trapezoidal protrusion plus the top width of the trapezoidal protrusion. This portion of the top width of the trapezoidal protrusion is defined as the first support surface. When the blocks are stacked one on top of the other, the bottom surface of the inverted trapezoidal protrusion on the water-facing side fits against the first support surface of the top side surface.
[0007] In some embodiments, the upper side of the outer side of the waist of the inverted trapezoidal protrusion located on the water-facing side is connected to the lower side of the water-facing side, and the outer side and the water-facing side form a V-shaped water-facing surface.
[0008] In some embodiments, the cross-sections of the trapezoidal protrusion, the trapezoidal groove, and the inverted trapezoidal protrusion are all isosceles trapezoids of the same shape.
[0009] In some embodiments, the precast block body is provided with ecological holes extending along the axial direction of the precast block body, and the ecological holes are surrounded by the water-facing side, the back side, the top side and the bottom side.
[0010] Compared with the prior art, the present invention has the following advantages when adopting the above structure: In this disclosure, it is surrounded by a water-facing side, a back side, a top side, and a bottom side. The top side is horizontally arranged and has a trapezoidal protrusion on the side near the back side. The trapezoidal protrusion extends along the axial direction of the precast block body. The bottom side is horizontally arranged and has a trapezoidal groove in the middle. The trapezoidal groove extends along the axial direction of the precast block body. The cross-section of the trapezoidal protrusion is the same as the cross-section of the trapezoidal groove. When the blocks are stacked, the trapezoidal groove and the trapezoidal protrusion cooperate to make the stacked blocks staggered. The trapezoidal protrusion and the trapezoidal groove can slide relative to each other along the axial direction of the precast block body. Therefore, it is beneficial to realize the laying of various revetments, thereby simplifying production and construction.
[0011] Compared with the prior art, this utility model also proposes a revetment, which includes multiple layers arranged from bottom to top, each layer being made of blocks laid sequentially along the length of the revetment, and the blocks are the aforementioned blocks.
[0012] Compared with the prior art, the present invention has the following advantages after adopting the above structure: In this disclosure, three different forms of revetment can be constructed from one type of block, and the front and rear are naturally staggered when stacked, which is conducive to simplifying production and construction.

Detailed Implementation
[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The embodiments described below are merely examples, and other obvious variations will arise for those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.
[0020] The present invention will now be described in further detail:
[0021] This disclosure provides a type of block that is produced through prefabrication and then laid, avoiding the drawbacks of cast-in-place production. The prefabrication method can employ dry molding, a production method that involves adding sand, cement, and other materials to a mold, pressing and shaping it, and then demolding to obtain the product. While concrete can also be used as prefabricated components, dry molding offers higher production efficiency, lower costs, and helps shorten the production cycle and reduce project investment.
[0022] like Figures 1 to 4 As shown, the specific structure of the block is as follows: it includes a precast block body 1, which includes an inwardly inclined water-facing surface 2, a vertically arranged back surface 3, a top surface 4, and a bottom surface 5. The top surface 4 is horizontally arranged and has a trapezoidal protrusion 6 on the side near the back surface 3. The lower side of the inner waist side of the trapezoidal protrusion 6 is connected to the upper side of the back surface 3. The trapezoidal protrusion 6 extends along the axial direction of the precast block body 1. The bottom surface 5 is horizontally arranged and has a trapezoidal groove 7 in the middle. The trapezoidal groove 7 extends along the axial direction of the precast block body 1. The cross-section of the trapezoidal protrusion 6 is the same as the cross-section of the trapezoidal groove 7. When the blocks are stacked, the trapezoidal groove 7 and the trapezoidal protrusion 6 cooperate to make the stacked blocks staggered front and back. The trapezoidal protrusion 6 and the trapezoidal groove 7 can slide relative to each other along the axial direction of the precast block body 1.
[0023] In some embodiments, such as Figure 1 , 2As shown, two inverted trapezoidal protrusions 8 with the same structure are respectively provided on both sides of the trapezoidal groove 7. The inverted trapezoidal protrusions 8 extend along the axial direction of the precast block body 1, and the cross-section of the inverted trapezoidal protrusions 8 is the same as the cross-section obtained by inverting the trapezoidal protrusions 6. This facilitates the backfill soil 15 to enter between the adjacent upper and lower blocks.
[0024] Furthermore, such as Figure 1 , 2 As shown, the width of the top side 4 is formed by the bottom width of the trapezoidal protrusion 6 plus the top width of the trapezoidal protrusion 6. This part of the top width of the trapezoidal protrusion 6 is defined as the first support surface 9. When the blocks are stacked up and down, the bottom surface of the inverted trapezoidal protrusion 8 located on the water-facing side 2 is in close contact with the first support surface 9 of the top side 4.
[0025] Furthermore, such as Figure 1 , 2 As shown in Figure 3, the upper side of the outer side 10 where the waist of the inverted trapezoidal protrusion 8 is located on the water-facing side 2 is connected to the lower side of the water-facing side 2, and the outer side 10 and the water-facing side 2 form a V-shaped water-facing side 2. In this way, when the blocks are stacked one on top of the other to form a revetment, the entire revetment can form a continuous corrugated surface on the water-facing side, and because the upper side of the outer side 10 where the waist of the inverted trapezoidal protrusion 8 is located on the water-facing side 2 is connected to the lower side of the water-facing side 2, the corrugated surface has good continuity.
[0026] In this example, the cross-sections of the trapezoidal protrusion 6, the trapezoidal groove 7, and the inverted trapezoidal protrusion 8 are all isosceles trapezoids with the same shape.
[0027] In some embodiments, such as Figure 1 , 2 As shown, the precast block body 1 is provided with ecological holes 11 extending along the axial direction of the precast block body 1. The ecological holes 11 are surrounded by the water-facing surface 2, the back surface 3, the top surface 4, and the bottom surface 5. This is beneficial for ecological design.
[0028] When stacking blocks to form a revetment, such as Figure 3 , 4 As shown, firstly, a bolt foundation 14 is made on the foundation. The bolt foundation is located under the bottom side 5 of the lowest layer of masonry block, and the bolt foundation is provided with a trapezoidal protrusion 6. The trapezoidal groove 7 of the lowest layer of masonry block is matched with the trapezoidal protrusion 6 of the bolt foundation.
[0029] Furthermore, the bolt foundation 14 is provided with a thrust cone 16 at the bottom front end, which helps the blocks to be stacked more stably on the bolt foundation 14.
[0030] This disclosure provides examples of two types of riverbank protection, the first type being... Figure 3In the first embodiment shown, when the blocks are stacked, the trapezoidal groove 7 of the upper block engages with the trapezoidal protrusion 6 of the adjacent lower block, and the end faces of adjacent blocks in the same layer are abutted together. The second embodiment... Figure 4 In the second embodiment shown, when the blocks are stacked, the trapezoidal groove 7 of the upper block and the trapezoidal protrusion 6 of the adjacent lower block cooperate with each other, and the end faces of adjacent blocks in the same layer are spaced apart, which forms an ecological groove 12, which is connected to the ecological hole 11.
[0031] Of course, there can also be a third type, such as some of the adjacent blocks on the same floor being set with their end faces touching, while the other part of the blocks are set with gaps, thus forming a variety of combinations.
[0032] To make the bank protection more stable, a top pressure block 13 is also included. The top pressure block 13 is located on the top side 4 of the uppermost block, and the top pressure block 13 is provided with a trapezoidal groove 7, which is matched with the trapezoidal protrusion 6 of the uppermost block.
[0033] When understanding this disclosure, the above structure may be referred to other embodiments / appendices if necessary. Figure 1 And that is understood, so I will not elaborate further here.
[0034] The above description is merely an illustrative embodiment of this disclosure. Therefore, all equivalent changes or modifications made to the structure, features, and principles described in this disclosure are included within the scope of protection of this disclosure.
