Description

Technical Field

[0001] The invention relates to a permeable brick paving technology, and in particular to a permeable brick paving structure capable of improving the water permeability of the permeable bricks. Background Art

[0002] Permeable bricks originated in the Netherlands. In the process of building cities by enclosing the sea, the Dutch found that the ground after draining the seawater would cause continuous ground subsidence due to long-term lack of water. Once the dam on the coastline is washed away, the seawater will quickly rush to the city much lower than the sea level and submerge the entire coastal city. In order to prevent the ground from sinking, the Dutch made a small road brick with a length of 100 mm, a width of 200 mm, and a height of 50 or 60 mm, which was laid on the street pavement, and a 2 mm gap was reserved between the bricks. In this way, when it rains, rainwater will seep into the ground from the gaps between the bricks.

[0003] Although permeable bricks have a certain water permeability, they can speed up water penetration compared to traditional bricks, thereby reducing the accumulation of stagnant water. Of course, there are also many existing methods. When laying permeable bricks, the gaps between the permeable bricks are appropriately increased to expand the water permeability of the permeable bricks. However, long-term use of this method will cause impurities to remain between the gaps, affecting the water permeability. Some methods also add sand bases or grids to the foundation, but do not adjust and control the permeable bricks, which will also affect the water permeability of the permeable bricks. Therefore, it is urgently necessary to design a permeable paving structure that can efficiently improve the water permeability of permeable bricks to solve the shortcomings of the existing technology. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the gaps between permeable bricks in the prior art limit the water permeability of the ground, or cannot avoid the defect of impurities being accumulated in the gaps between the bricks.

[0005] In order to solve the above technical problems, the technical solution provided by the present invention is:

[0006] A permeable brick permeable paving structure comprises a first bottom plate and a second bottom plate arranged in parallel, wherein the first bottom plate and the second bottom plate are fixed to the ground foundation by fastening screws; the first bottom plate 1 is connected to the first support plate by a first torsion column; the second bottom plate is connected to the second support plate by a second torsion column. The first torsion column and the second torsion column are both composed of an upper support, a rotating shaft and a lower support, wherein the upper support and the lower support are connected by a rotating shaft; the lower support of the first torsion column is fixed to the first bottom plate, and the lower support of the second torsion column is fixed to the second bottom plate; the upper support of the first torsion column is fixed to the first support plate, and the upper support of the second torsion column is fixed to the second support plate. The adjacent sides of the first support plate and the second support plate are connected by a pin. Coil springs are respectively installed between the two sides of the first support plate and the first bottom plate, and between the two sides of the second support plate and the second bottom plate.

[0007] The beneficial effects of the present invention are:

[0008] In the present invention, permeable bricks are laid on the first support plate and the second support plate, and the first support plate and the second support plate are connected by a pin shaft, so that the support plates can be rotated, and the spiral spring can automatically reset. The permeable brick paving structure provided by the present invention slightly flips the brick surface when pedestrians pass by, so that the permeable brick road surface can effectively seep water, and automatically resets after the pedestrians leave, avoiding the clogging of the gap by impurities, and effectively solving the contradiction between the smooth road surface seepage and the excessive accumulation of impurities.

[0020] The following will be combined with the attached Figure 1-4 The technical solution of the present invention is described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this technical solution can be understood according to specific circumstances.

[0022] A permeable brick permeable paving structure comprises a first bottom plate 1 and a second bottom plate 2 arranged in parallel, wherein the first bottom plate 1 and the second bottom plate 2 are fixedly connected to the ground foundation by fastening screws. The first bottom plate 1 is connected to the first support plate 3 by a first torsion column; the second bottom plate 2 is connected to the second support plate 4 by a second torsion column. The first torsion column and the second torsion column are both composed of an upper support 5, a rotating shaft 7 and a lower support 6, wherein the upper support 5 and the lower support 6 are connected by the rotating shaft 7; the lower support 6 of the first torsion column is fixedly connected to the first bottom plate 1, and the lower support 6 of the second torsion column is fixedly connected to the second bottom plate 2; the upper support 5 of the first torsion column is fixedly connected to the first support plate 3, and the upper support 5 of the second torsion column is fixedly connected to the second support plate 4. The adjacent sides of the first support plate 3 and the second support plate 4 are connected by a pin 9. Coil springs 10 are respectively installed between the two sides of the first support plate 3 and the first bottom plate 1, and between the two sides of the second support plate 4 and the second bottom plate 2.

[0023] like Figure 1-2 As shown, the upper parts of the first bottom plate 1 and the second bottom plate 2 are respectively fixed with hydraulic cylinders 8, and the lower support 6 is fixed with the hydraulic cylinders 8. The model of the hydraulic cylinders 8 is an ENERPAC oil cylinder. The hydraulic cylinders 8 can adjust the overall height of the present invention, so as to be applicable to foundations of various depths.

[0024] The first support plate 3 and the second support plate 4 are collectively referred to as support plates, and permeable bricks 11 are laid on the support plates. Figure 3 As shown, after the foundation is prepared, the paving structure provided by the present invention is arranged in the foundation pit, and all the first support plates 3 and the second support plates 4 are combined into a paving base for the permeable bricks 11. The first support plates 3 and the second support plates 4 are mesh structures. The mesh structure of the support plates further enhances the water permeability.

[0025] The upper support 5 is a U-shaped plate, and its arc end overlaps with the lower support 6. A rotating shaft 7 is installed in the overlapping range. The rotating shaft 7 can be a rotating rod rotating shaft or a ball shaft. The upper support 5 and the lower support 6 form a movable connection, mainly to realize that the top surface of the upper support can be tilted and swung.

[0026] The spiral spring 10 is a thrust spring. The spring is used to provide thrust, thereby accelerating the reset of the support plate and making the permeable brick smoother.

[0027] When installing the device, multiple groups of the device are installed in the excavated foundation, and the present invention is fixed with fastening screws, and then permeable bricks 11 are laid on the first support plate 3 and the second support plate 4, and a sand base is laid between the support plate and the permeable bricks to achieve paving of the permeable bricks.

[0028] The working principle of the permeable brick permeable paving structure provided by the present invention is as follows:

[0029] Due to the certain cavity supported by the support plate and a series of components below the support plate, the surface water can penetrate downward smoothly, and the permeability of the permeable brick floor is enhanced.

[0030] When pedestrians walk on the permeable bricks, the support plates tilt slightly, which makes the contact surface between the permeable bricks smaller and the gap larger, making water seepage smooth. Due to the thrust provided by the spiral spring 10, the permeable bricks 11 can be immediately reset after the person leaves, and the gap is restored to avoid clogging by garbage in the gap.

[0031] The gap between the pavement bricks formed by the permeable brick paving structure designed by the present invention is not fixed. Since the gap between the permeable bricks is variable, the width of the reserved seam can be reduced when paving the bricks, making the road surface smoother.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1) A certain space is supported between the bottom plate and the supporting plate, forming a certain cavity under the permeable bricks to improve the water permeability of the permeable brick floor.

[0034] 2) The support plate can be slightly tilted and automatically reset. When tilted, water can flow quickly, thereby avoiding the accumulation of water above the permeable bricks. After rapid reset, impurities can be prevented from entering the brick joints.

[0035] 3) The present invention is buried underground and cannot be observed from the surface. By using the structure as the paving foundation of permeable bricks, the reserved gaps of the permeable bricks can be reduced, and the road surface is more beautiful.

[0036] 4) The present invention only needs to fix the paving structure on the ground to form a plane supporting the permeable bricks on the top surface, and the permeable bricks can be directly paved on the supporting plate, which is convenient for installation.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
