Description
Technical Field
[0001] The utility model relates to the technical field of river bank slope protection, in particular to a top-pressed grass-planting brick. Background Art
[0002] The top grass brick is made of high-quality materials such as concrete or new ecological concrete poured into a mold and vibrated by a vibrator. After scientific and systematic maintenance, the grass brick has good compressive resistance and structural strength. It has good stability when used as the top of the river bank protection, with a wide greening area, and can withstand water erosion without being damaged. At the same time, the roots of the green grass grow under the grass brick, which will not cause damage to the grass roots. Therefore, the grass brick has been widely used. It not only meets the requirements of water conservancy projects for bank protection structures, but also increases the greening area of the river.
[0003] Ecological interlocking grass bricks are widely used in ecological environment governance projects. They can be used as the top material of embankment or ditch slope protection bricks to increase the greening area of the slope. Usually, manufacturers mass-produce grass bricks according to design drawings. The porosity is not less than 35%. The shape is rectangular and symmetrical at both ends. The side bumps and mortise and tenon grooves form an interlocking structure with adjacent bricks to enhance the connection between bricks.
[0004] Since the single unit shape is mostly rectangular, the top grass bricks are restricted by the fixed shape and position of the side protrusions and the mortise and tenon, making it difficult to lay in winding rivers. In the construction of water conservancy projects, it is usually adopted to straighten the winding river to reduce the difficulty of laying grass bricks in the turning section of the river, or to cut the grass bricks and then bond them with mortar, which greatly tests the construction technology, and there is a high probability of material waste in the process of cutting bricks.

[0036] The utility model provides a top-pressed grass-planting brick, which is combined with Figures 1 to 7 The utility model is described with reference to the structural schematic diagram, but it should be understood that the protection scope of the utility model is not limited by the specific implementation methods.
[0037] Example 1
[0038] like Figure 1 As shown, the utility model provides a top-pressed grass brick, comprising: a body 1 and a connecting block 2. The cross section of the body 1 is an integrated shape composed of a rectangle and an isosceles trapezoid, the isosceles trapezoid has two waists and a first side and a second side (the upper base and the lower base of the isosceles trapezoid respectively), the second side is longer than the first side, the rectangle has a third side and a fourth side, the third side and the fourth side are a group of adjacent sides, the third side of the rectangle is connected to the second side of the isosceles trapezoid, a through hole is provided in the body 1, the shape of the through hole is consistent with the shape of the cross section of the body 1, the angle between the waist of the isosceles trapezoid and the extension line of the fourth side of the rectangle is θ, θ is an acute angle, the body 1 is a hexamorphosis, which is equivalent to a rectangular frame structure with a group of adjacent corners cut off, such as Figure 6 The upper part of the main body 1 is formed into an isosceles trapezoid shape; two connecting blocks 2 are symmetrically arranged on both sides of the main body 1, and the connecting blocks 2 are used to be rotatably connected with the connecting blocks 2 of the adjacent main body 1. The connecting blocks 2 are arranged on both sides of the main body 1 of the grass-planting brick, which can be rotatably connected with the adjacent main body 1, so that it is convenient to adjust the angle between the two adjacent main bodies 1 according to the curvature of the river channel, so that the main body 1 of the top grass-planting brick can be rotated arbitrarily with the curvature of the river channel, which not only enhances the mutual interlocking and nesting force of the top grass-planting bricks in the winding river channel, but also makes it unnecessary to deliberately straighten the river channel during river channel management, which is more in line with the principle of river channel ecological management. The main body 1 of the device is set to such a shape in order to avoid collision between the two rotating bodies when adjusting the angle between the two main bodies 1. At the same time, the rectangular shape of the existing brick body also leads to a small angle adjustment range between the two main bodies 1, which cannot adapt well to the curvature of the river channel. The dimensions of the main body 1 are length: 450mm (356mm) × width: 400mm × height: 120mm, and the wall thickness is 45mm (referring to the thickness between the through hole and the outer wall of the main body 1). Under this dimension, the porosity of the grass brick can reach 62%. The angle θ is related to the dimensions selected for the main body 1, and under this dimension, θ is 15°. In addition, the connecting block 2 plays the role of connecting two adjacent grass bricks on the one hand, and on the other hand, it can adjust the angle between two adjacent grass bricks, so as to facilitate the application of grass bricks beside winding rivers.
[0039] like Figure 7 As shown, further, the top surface of one of the connection blocks 2 is flush with the top surface of the body 1, and the bottom surface of the other connection block 2 is flush with the bottom surface of the body 1, as shown in FIG. Figure 2 , 3 As shown, two connection blocks 2 are staggered, and the distance between the bottom surface of one connection block 2 and the top surface of the other connection block 2 is d, and d is used to make the connection blocks 2 between two adjacent bodies 1 fit in clearance. That is, the opposite surfaces of the connection blocks 2 between two adjacent bodies 1 can abut against each other or have a certain spacing. Among them, the top surfaces of the two connection blocks 2 can be flush with the top surface of the body 1, as long as the two connection blocks 2 of the two adjacent bodies 1 are connected, one of the connection blocks 2 is located above the other connection block 2, so that the two connection blocks 2 are stacked up and down.
[0040] Furthermore, the connecting block 2 includes: a first block 21 and a second block 22. The first block 21 is fixed on the side wall of the body 1; the second block 22 has a semicircular cross section and is fixed on the side of the first block 21 away from the body 1. Figure 4 As shown, the second block 22 is an arc-shaped block, and the end of the connecting block 2 away from the main body 1 is an arc-shaped, so that when the angle between the two main bodies 1 is adjusted, collision between the main bodies 1 during rotation can be avoided.
[0041] like Figure 6 As shown, further, two protrusions 11 are respectively arranged on both sides of the body 1, and the two protrusions 11 are respectively located at the two waists of the isosceles trapezoid. The protrusions 11 are respectively arranged on both sides of the body 1, which can play a role in protecting the body 1, and can avoid collision between the two bodies 1 when adjusting the angle between the two bodies 1. Among them, the protrusion 11 can be made of the same material as the body 1 to form an integrated structure, and can also be made of a flexible material, which plays a role in buffering protection when the two bodies 1 are in contact.
[0042] Example 2
[0043] As a further improvement on Example 1, Figure 6As shown, further, it also includes a connecting shaft 4, wherein the second block 22 of one connecting block 2 is vertically penetrated by a first connecting hole 3, and the second block 22 of the other connecting block 2 is vertically penetrated by a second connecting hole, the connecting shaft 4 is penetrated in the first connecting hole 3 and the second connecting hole, and the connecting shaft 4 is rotatably connected to the first connecting hole 3 and the second connecting hole respectively, and the rotatable connection structure can be that an annular groove is opened in the circumference of the first connecting hole 3 and the second connecting hole, and a connecting rod is arranged on the side wall of the connecting shaft 4, so that the end of the connecting rod away from the connecting shaft 4 is clamped in the annular groove and is slidably connected to the annular groove to achieve rotatable connection, and the connecting shaft 4 can be made of fiberglass anchor rods or steel bars. When the top grass bricks are actually installed beside the river channel, there is no need to connect the connecting shaft 4 with the first connecting hole 3 and the second connecting hole. It is sufficient that the connecting shaft 4 is clamped in the first connecting hole 3 and the second connecting hole and the two main bodies 1 can rotate relative to the connecting shaft 4. This makes it convenient to adjust the angle between the two main bodies 1 according to the curvature of the river channel. In the specific implementation, the slope protection top position is arranged according to the river bank line, the first connection hole 3 and the second connection hole of the two connecting blocks 2 of the adjacent main body 1 are aligned, the connecting shaft 4 is inserted into the first connection hole 3 and the second connection hole, and the series main body 1 is rotated according to the curvature of the river. Among them, the connecting shaft 4 can be replaced by embedded bolts, and fixed with nuts after adjusting the position of the main body 1. The diameter of the first connecting hole 3 and the second connecting hole is selected to be 40mm, the diameter of the connecting shaft 4 is 20mm, and the length is 120mm; the size of the connecting block 2 is: length: 55mm×width: 50mm×height: 60mm.
[0044] like Figure 5 As shown, further, stoppers 41 are respectively provided at both ends of the connecting shaft 4, and one of the stoppers 41 is detachably connected to the connecting shaft 4. When in use, the connecting shaft 4 is inserted into the first connecting hole 3 and the second connecting hole, and then one of the stoppers 41 is connected to the connecting shaft 4 to fix the two ends of the connecting shaft 4 to prevent the connecting shaft 4 from slipping out of the hole.
[0045] Furthermore, the detachable connection between the stopper 41 and the connecting shaft 4 is a threaded connection, and a slot hole is opened on the stopper, an internal thread is arranged in the slot hole, and a threaded section is arranged at the end of the connecting shaft 4, so that the connecting shaft 4 is threadedly connected to the slot hole.
[0046] Among them, other structures of this embodiment are consistent with those of embodiment 1, and are just optimizations made to embodiment 1.
[0047] Example 3
[0048] As a further improvement on Example 2, Figure 6 As shown, it also includes: a limiting structure is arranged on the opposite side of the two connecting blocks 2, which is used to limit the rotation angle range of the two bodies 1 to avoid excessive rotation causing collision between the two bodies 1, so a limiting structure is set, such as Figure 3 As shown, the limiting structure includes: a fan-shaped groove 23 and a fan-shaped protrusion 24. The fan-shaped groove 23 is provided on the side wall of one of the connection blocks 2; the fan-shaped protrusion 24 is provided on the side wall of the other connection block 2, and the fan-shaped protrusion 24 is used to be clamped with the fan-shaped groove 23 of the adjacent body 1, the central angle of the fan-shaped groove 23 is greater than the central angle of the fan-shaped protrusion 24, the fan-shaped protrusion 24 is cocentric with the fan-shaped groove 23, and the fan-shaped protrusion 24 is located on one side of the connection shaft 4. In addition, the positions of the fan-shaped groove 23 and the fan-shaped protrusion 24 can be interchanged, that is, the fan-shaped protrusion 24 can be provided on any one of the two connection blocks 2, and the fan-shaped groove 23 can be provided on the other, without affecting the limiting function.
[0049] like Figure 4 As shown, further, the difference between the central angle of the sector groove 23 and the central angle of the sector protrusion 24 is 2θ. Under the actual size of the body 1 of the present device, θ is 15°, then the difference between the central angle of the sector groove 23 and the central angle of the sector protrusion 24 is 30°, the central angle of the sector groove 23 is 150°, and the central angle of the sector protrusion 24 is 120°.
[0050] Furthermore, θ is 10°-30°. If θ is too small, the two adjacent main bodies 1 may collide with each other when adjusting the angle between them, and if θ is too large, the gaps left by the grass bricks during installation are too large, which is not conducive to slope protection.
[0051] Among them, the other structures of this embodiment are consistent with those of Embodiment 2, and are just optimizations made to Embodiment 2.
[0052] The advantage of the utility model is that the connecting blocks are arranged on both sides of the main body of the grass brick, which can be rotatably connected with the adjacent main body, so that the angle between the two adjacent main bodies can be adjusted according to the curvature of the river channel, so that the main body of the top grass brick can be rotated arbitrarily with the curvature of the river channel, and can be laid in the winding river channel, while avoiding material waste, which not only enhances the mutual bite and nesting force of the top grass brick in the winding river channel, but also makes it unnecessary to deliberately straighten the river channel during river channel management, which is more in line with the principle of river channel ecological management. At the same time, a limiting structure is also provided, which can limit the angle range of the rotation of the two main bodies to avoid excessive rotation causing collision between the two main bodies.
[0053] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
