Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy projects, specifically relates to the field of breakwater face protection projects, and in particular relates to a cannon-shaped face protection block. Background Art

[0002] Breakwaters are hydraulic structures used to defend against wave intrusion, and slope embankment structures are widely used due to their stability, ease of construction, good stability, and strong foundation adaptability. As an important component of slope embankments, face protection blocks are laid on the surface of the slope embankment, directly facing the impact of waves and protecting the core material of the embankment. Face protection blocks are mainly divided into stone blocks and artificial blocks. Stone blocks are generally obtained through mining and crushing, and their wave-breaking effect is average and the landscape is poor. In areas with high waves and severe wave impacts, it is calculated that a single block weighs several tons, and the demand for stone blocks is huge, and mining and transportation are difficult.

[0003] Therefore, artificial blocks are often used as protective blocks in engineering projects. Common ones include twisted king blocks and twisted I blocks. These block structures are mostly heterogeneous structures, and the installation methods include random placement and regular placement of one layer or two sides, with good wave-breaking effects. Twisted king blocks and twisted I blocks often need to be connected to each other to maintain their stability in order to cope with the impact of wind and waves. Regular placement of blocks can ensure good connection between blocks, but the placement workload is large, the construction time is long, and the project investment is large. If the blocks are randomly placed, the block connectivity cannot be guaranteed, and the stability is poor. In extreme weather, the blocks may overturn, slide, scatter, etc., resulting in reduced block protection effect. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a cannon-shaped armor block, which can solve the problem that the existing armor blocks cannot ensure connectivity and have poor stability under the random placement installation method, while improving the wave-breaking effect and economy of the armor blocks.

[0005] A cannon-shaped armor block comprises a center body, an upper body, and a lower body. The upper and lower bodies are respectively disposed at the top and bottom of the center body. The center body has an X-shaped column structure formed by vertically extending inwardly convex trapezoidal holes on the inner side of each of the four sides of the rectangular column top surface. Both the upper and lower bodies are outward-facing column structures.

[0006] Optionally, the top and bottom surfaces of the rectangular cylinder are squares, the side lengths of the top and bottom surfaces are h, and the height of the rectangular cylinder is h / 3.

[0007] Optionally, the inwardly convex trapezoidal through hole is symmetrically arranged in the middle position of the four sides of the top surface of the rectangular cylinder, and the outer shape of the inwardly convex trapezoidal through hole is an isosceles trapezoid, and the bottom side of the isosceles trapezoid coincides with the outer side of the top surface of the rectangular cylinder.

[0008] Optionally, the base angle of the isosceles trapezoid is 45°.

[0009] Optionally, a sloped surface is provided on both the upper and lower end surfaces of the rectangular X-pillar structure, parallel to the length of the side of the rectangular X-pillar structure. Furthermore, the sloped surface has a length of (0.20-0.225) h along the length of the rectangular X-pillar, and a thickness of (0.03-0.05) h along the height of the rectangular X-pillar.

[0010] Preferably, in order to ensure that the four teeth columns of the X-column structure have good structural strength, the width of the teeth columns should be (1 / 4~1 / 3)h.

[0011] Optionally, the lower body has the same structural type as the upper body, and both the upper and lower bodies are formed based on a prism by providing chamfered surfaces. The upper and lower bases of the prism are both rectangular, such as a square. Furthermore, the side length of the lower base rectangle is h / 3, and the side length of the upper base rectangle is (1 / 4 to 1 / 3)h.

[0012] Optionally, the upper end body is connected to the upper end surface of the intermediate body through a rectangular bottom surface, and the side length of the bottom surface of the upper end body is perpendicular to the diagonal line of the X-column.

[0013] Optionally, a triangular reinforcement angle is provided at the connection between the upper end body and the middle body; and / or a triangular reinforcement angle is provided at the connection between the lower end body and the middle body.

[0014] Optionally, triangular chamfered surfaces are provided at the four end corners of the pyramid body, the triangular bases of the triangular chamfered surfaces are located on the top surface of the pyramid body, and the triangular vertices of the triangular chamfered surfaces are located on the top of the reinforced angle.

[0015] The beneficial effects of the utility model include:

[0016] (1) Compared with commonly used armor blocks, the gun-shaped armor block disclosed in the present invention has an X-shaped tooth foot in the middle body and an outward-facing column structure in the upper and lower end bodies. The blocks are easily connected to each other. When the blocks are randomly placed, the stability of the blocks is better than that of commonly used armor blocks.

[0017] (2) The placement density of the cannon-shaped face blocks is lower than that of commonly used face blocks, and the void ratio between the blocks is higher. Under the same protection function, the number of blocks and the amount of concrete used are both less than those of commonly used face blocks, which can save engineering costs. At the same time, the larger void ratio between the blocks also makes the blocks have better wave-breaking effect and ecological properties. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] See also Figure 1-4 For example, a cannon-shaped armor block includes a middle body 10, an upper end body 20, and a lower end body 30. The middle body 10 has an upper end face and a lower end face opposite to each other. The upper end body 20 and the lower end body 30 are symmetrically connected to the upper end face and the lower end face of the middle body 10, respectively. The upper end body and the lower end body are both outward-facing column structures.

[0031] The intermediate body 10 is formed based on a rectangular cylinder by setting an inwardly convex trapezoidal through hole 11 and a slope surface 12. For example, the top and bottom surfaces of the rectangular cylinder are squares, the side lengths of the top and bottom surfaces of the rectangular cylinder are h, and the height of the rectangular cylinder is h / 3.

[0032] The inward-convex trapezoidal through hole 11 is symmetrically arranged in the middle of the four sides of the rectangular column. The outer shape of the inward-convex trapezoidal through hole 11 is an isosceles trapezoidal column with a trapezoidal bottom angle of 45°. The bottom side of the isosceles trapezoid coincides with the outer side of the top of the rectangular column. After the rectangular column is provided with four inward-convex trapezoidal through holes, an X-column structure is formed.

[0033] In order to ensure that the four teeth columns (i.e., the wings on the corner sides) of the X-column structure have good structural strength, the width of the teeth columns should be (1 / 4~1 / 3)h.

[0034] On the upper and lower end surfaces of the rectangular X-pillar structure, a slope surface 12 is provided along the direction parallel to the length of the X-pillar.

It can be understood that, if Figure 1 As shown, the slope surface 12 refers to a rectangular frame (the rectangular frame in the middle position in the figure) built into the upper and lower end surfaces of the rectangular X-column structure. The four sides of the rectangular frame are parallel to the four sides of the top surface of the rectangular column, and the rectangular frame is located outside the upper or lower end body. The side length of the rectangular X-column, the adjacent diagonals of the rectangular X-column, and each side of the rectangular frame together form the slope surface 12. For example, the slope surface 12 can be divided into an inner side and an outer side. The outer side is parallel to the inner side, and the inner side has the same height and is higher than the outer side to form a slope surface.

[0035] The upper end body 20 is formed based on a prism body by setting a chamfered surface 50, the height of the prism body is h / 3, the upper base and the lower base of the prism are both rectangular, such as a square, the side length of the lower base rectangle is h / 3, and the side length of the upper base rectangle is (1 / 4~1 / 3)h.

[0036] The upper end body 20 is connected to the upper end surface of the intermediate body 10 through a lower bottom rectangular shape, and the side length of the lower bottom rectangular shape is kept perpendicular to the diagonal of the rectangular X-column.

[0037] A triangular reinforcement angle 40 is provided at the connection between the upper end body 20 and the middle body 10 , and a triangular reinforcement angle 40 may also be provided at the connection between the lower end body and the middle body 10 .
