Description

Technical Field

[0001] The present application relates to the technical field of building materials, and in particular to a permeable brick and a pavement structure. Background Art

[0002] Permeable pavement is an important technology in the construction of sponge cities. It can quickly infiltrate and drain water from roads. It can also reduce the burden on urban drainage facilities during heavy rain and rainstorms, and ensure the comfort of residents' travel. Generally, permeable bricks, permeable concrete, and permeable cement-stabilized gravel, which have good water permeability and high porosity, are used in the road surface, base layer, and even soil foundation.

[0003] Traditional permeable road base construction mostly adopts the direct pouring method of permeable concrete. Permeable concrete is a dry and hard concrete with less slurry and short initial setting time. It is not suitable to be retained for a long time after mixing. Therefore, most of the current permeable concrete is mixed on-site. The on-site mixing of permeable concrete will bring a series of problems, such as large fluctuations in material quality, noise and dust, serious waste of materials, long curing time of permeable concrete base and low construction efficiency.

[0004] Chinese patent CN211036601U discloses a steel slag gap permeable brick, which does not require on-site mixing, but rather achieves the splicing of multiple permeable brick bodies by overlapping grooves and overlapping protrusions, thereby avoiding a series of problems caused by on-site mixing. However, this type of permeable brick is only spliced ​​by protrusions and grooves, and the bonding between adjacent permeable bricks after splicing is not strong. Therefore, the existing permeable bricks have the problem of weak bonding between adjacent permeable bricks after splicing. Utility Model Content

[0005] The purpose of the present application is to provide a permeable brick that improves the adhesion of adjacent permeable bricks after being assembled, which includes a first hole wall and a second hole wall, wherein the first hole wall and the second hole wall are located on different sides of the permeable brick.

[0008] Optionally, the third hole wall and the fourth hole wall are located on different long side portions of the permeable brick.

[0010] Optionally, the first hole wall, the first clamping protrusion, the first clamping recess and the second hole wall are semi-cylindrical, and the distance from the center axis of the first clamping protrusion to the center axis of the first hole wall is equal to the distance from the center axis of the first clamping recess to the center axis of the second hole wall.

[0014] The present application also provides a pavement structure, which includes a soil roadbed, a crushed stone layer, a permeable brick layer and a permeable asphalt layer which are sequentially supported from bottom to top, and the permeable brick layer includes a plurality of the permeable bricks.

[0015] The beneficial effect of the present application is that by setting the first hole wall and the second hole wall on the permeable brick, the first hole wall and the second hole wall are located on different sides of the permeable brick, and when the permeable brick is laid, the first hole wall and the second hole wall of two adjacent permeable bricks are pieced together to form a first through hole for filling concrete.

[0038] The following is an explanation of the implementation of the present application by means of specific embodiments. People familiar with the technology can easily understand other advantages and effects of the present application from the contents disclosed in this specification.

[0039] It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and in combination with the embodiments. In order to enable those skilled in the art to better understand the present application scheme, the technical scheme in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only embodiments of a part of the present application, not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in the field without making creative work should fall within the scope of protection of the present application.

[0040] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0041] 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 a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0042] For the convenience of explanation, a rectangular coordinate system O-XYZ is established in some of the accompanying drawings, where the X-axis is parallel to the width direction of the permeable brick 1, the Y-axis is parallel to the length direction of the permeable brick 1, and the Z-axis is parallel to the thickness direction of the permeable brick 1. The positive direction of the X-axis, the positive direction of the Y-axis, and the positive direction of the Z-axis remain the same in each of the accompanying drawings with a coordinate system.

[0043] Please also refer to Figure 1 and Figure 2In this embodiment, a permeable brick 1 is provided, which includes a first hole wall 100 and a second hole wall 101. The first hole wall 100 and the second hole wall 101 are located on different sides of the permeable brick 1. When the permeable brick 1 is laid, the first hole walls 100 and the second hole walls 101 of two adjacent permeable bricks 1 are assembled into a first through hole 10 for filling concrete. Since the first hole walls 100 and the second hole walls 101 of two adjacent permeable bricks 1 are assembled into a first through hole 10 for filling concrete during laying, the two adjacent permeable bricks 1 can be bonded by means of the concrete filled into the first through hole 10, thereby increasing the bonding property of the two adjacent permeable bricks 1. Filling the first through hole 10 with steel slag permeable concrete can also form a pile-type soft connection.

[0044] like Figure 1 As shown, the permeable brick 1 can be rectangular, with a length greater than or equal to 200 mm and less than or equal to 400 mm, a width greater than or equal to 110 mm and less than or equal to 220 mm, and a thickness greater than or equal to 100 mm and less than or equal to 150 mm. The material of the permeable brick 1 can be 28d strength, concrete grade C25 or above, and 5-15mm graded steel slag permeable concrete, and its permeability coefficient is greater than 2.0×10 -2 The concrete filled in the first through hole 10 may be permeable concrete. For example, the concrete filled in the first through hole 10 may be steel slag permeable concrete with an aggregate particle size greater than or equal to 1 mm and less than or equal to 3 mm, and a water permeability coefficient greater than 2.0×10 -2 cm / s.

[0045] like Figure 1 As shown, the first hole wall 100 and the second hole wall 101 can be located at the right side and the left side of the permeable brick 1, respectively. The first hole wall 100 and the second hole wall 101 can penetrate the upper and lower surfaces of the permeable brick 1. The central axis of the first hole wall 100 and the central axis of the second hole wall 101 can be parallel to the Z axis. The first hole wall 100 and the second hole wall 101 can be semi-cylindrical, and their diameters can be the same. For example, the radius range of the first hole wall 100 and the second hole wall 101 can be greater than or equal to 12 mm and less than or equal to 18 mm. When the permeable brick 1 is laid, the adjacent permeable bricks 1 can be directly abutted and spliced ​​or spliced ​​by the first snap-fitting protrusion 12 and the first snap-fitting recess 13 of the adjacent permeable bricks 1 in the subsequent content of the embodiment.

[0046] Please also refer to Figure 1 and Figure 2 Optionally, the first hole wall 100 and the second hole wall 101 are located at different long side portions of the permeable brick 1. In this way, the diameters of the first hole wall 100 and the second hole wall 101 can be made larger to form a first through hole 10 with a larger diameter, thereby accommodating more concrete. Figure 1 As shown, the first hole wall 100 and the second hole wall 101 can be located at the right long side and the left long side of the permeable brick 1 respectively.

[0047] Please also refer to Figure 1 and Figure 2 Optionally, the permeable brick 1 further includes a third hole wall 110 and a fourth hole wall 111, which are located at different sides of the permeable brick 1. When the permeable brick 1 is laid, the third hole walls 110 and the fourth hole walls 111 of two adjacent permeable bricks 1 are assembled into a second through hole 11 for filling with a sponge. After the second through hole 11 is filled with a sponge, the water retention and water storage capacity of the permeable brick 1 can be enhanced. The sponge can be a polymer absorbent resin or a rubber sponge.

[0048] like Figure 1 As shown, the third hole wall 110 and the fourth hole wall 111 may penetrate the upper and lower surfaces of the permeable brick 1. The third hole wall 110 and the fourth hole wall 111 may be located at the right side and the left side of the permeable brick 1, respectively. The central axis of the third hole wall 110 and the central axis of the fourth hole wall 111 may be parallel to the Z axis. The third hole wall 110 and the fourth hole wall 111 may be semi-cylindrical, and their diameters may be the same and the same as the diameter of the first hole wall 100 and the diameter of the second hole wall 101. For example, the radius range of the third hole wall 110 and the fourth hole wall 111 may be greater than or equal to 12 mm and less than or equal to 18 mm.

[0049] Please also refer to Figure 1 and Figure 2 Optionally, the third hole wall 110 and the fourth hole wall 111 are located at different long side portions of the permeable brick 1. In this way, the diameters of the third hole wall 110 and the fourth hole wall 111 can be made relatively large to form a second through hole 11 with a larger diameter, thereby accommodating a larger volume of sponge. Figure 1 As shown, the third hole wall 110 and the fourth hole wall 111 may be located at the right long side and the left long side of the permeable brick 1 respectively.

[0050] Please also refer to Figure 1 and Figure 2 Optionally, the permeable brick 1 also includes a first clamping protrusion 12 and a first clamping recess 13. The first hole wall 100, the third hole wall 110 and the first clamping protrusion 12 are located on one side of the permeable brick 1, and the second hole wall 101, the fourth hole wall 111 and the first clamping recess 13 are located on the other side of the permeable brick 1. When the permeable brick 1 is laid, the first clamping protrusions 12 and the first clamping recesses 13 of two adjacent permeable bricks 1 are clamped with each other.

[0051] Please also refer to Figure 1 and Figure 2In this way, the first engaging protrusion 12 of a permeable brick 1 can be used as a reference to engage with the first engaging recess 13 of another adjacent permeable brick 1 to form the correct number of first through holes 10 and second through holes 11. For example, if the first engaging protrusion 12 is not used as a reference, the second hole walls 101 of adjacent permeable bricks 1 may face each other, the fourth hole walls 111 of adjacent permeable bricks 1 may face each other, and the first engaging recesses 13 of adjacent permeable bricks 1 may face each other, resulting in the formation of three through holes. Figure 1 As shown, the first clamping protrusion 12 and the first clamping recess 13 can be located at the right long side and the left long side of the permeable brick 1 respectively.

[0052] like Figure 1 As shown, the upper and lower end surfaces of the first clamping protrusion 12 can be flush with the upper and lower surfaces of the permeable brick 1 respectively. The first clamping recess 13 can penetrate the upper and lower surfaces of the permeable brick 1. The first clamping protrusion 12 can be convex outward along the positive direction parallel to the X-axis, and the first clamping recess 13, the second hole wall 101 and the fourth hole wall 111 can be concave inward along the positive direction parallel to the X-axis. The first hole wall 100 and the third hole wall 110 can be concave inward along the negative direction parallel to the X-axis. The central axis of the first clamping protrusion 12 and the central axis of the first clamping recess 13 can be parallel to the Z axis. The first clamping protrusion 12 and the first clamping recess 13 can be semi-cylindrical, and their diameters can be the same and the same as the diameter of the first hole wall 100 and the diameter of the second hole wall 101. For example, the radius range of the first clamping protrusion 12 and the first clamping recess 13 can be greater than or equal to 12 mm and less than or equal to 18 mm.

[0053] Please also refer to Figure 1 and Figure 2 Optionally, the first hole wall 100, the first clamping protrusion 12, the first clamping recess 13 and the second hole wall 101 are semi-cylindrical, and the distance from the central axis of the first clamping protrusion 12 to the central axis of the first hole wall 100 is equal to the distance from the central axis of the first clamping recess 13 to the central axis of the second hole wall 101. With this arrangement, once the first clamping protrusions 12 and the first clamping recess 13 of two adjacent permeable bricks 1 are aligned, the first hole wall 100 and the second hole wall 101 can also be automatically aligned, so as to facilitate the formation of the first through hole 10.

[0054] Please also refer to Figure 1 and Figure 2Optionally, the third hole wall 110 and the fourth hole wall 111 are semi-cylindrical, and the distance from the central axis of the first clamping protrusion 12 to the central axis of the third hole wall 110 is equal to the distance from the central axis of the first clamping recess 13 to the central axis of the fourth hole wall 111. With this arrangement, once the first clamping protrusions 12 and the first clamping recesses 13 of two adjacent permeable bricks 1 are aligned, the third hole wall 110 and the fourth hole wall 111 can also be automatically aligned, so as to facilitate the formation of the second through hole 11.

[0055] Please also refer to Figure 1 and Figure 2 Optionally, the central axis of the first hole wall 100, the central axis of the first clamping protrusion 12 and the central axis of the third hole wall 110 respectively pass through the four equal points of one long side of the permeable brick 1, and the central axis of the second hole wall 101, the central axis of the first clamping recess 13 and the central axis of the fourth hole wall 111 respectively pass through the four equal points of the other long side of the permeable brick 1. With such an arrangement, concrete can be filled into each first through hole 10 formed by adjacent permeable bricks 1 along a straight line, and sponge can be filled into each second through hole 11 formed by adjacent permeable bricks 1 along a straight line, which facilitates the filling of concrete and sponge. For example, after the permeable bricks 1 are laid, concrete can be filled into each first through hole 10 in the same row along a straight line parallel to the X-axis, and sponge can be filled into each second through hole 11 in the same row along a straight line parallel to the X-axis.

[0056] like Figure 1 As shown, the central axis of the first hole wall 100, the central axis of the first snap-fit ​​protrusion 12 and the central axis of the third hole wall 110 can respectively pass through the four equal points of the right long side of the permeable brick 1, and the central axis of the second hole wall 101, the central axis of the first snap-fit ​​recess 13 and the central axis of the fourth hole wall 111 can respectively pass through the four equal points of the left long side of the permeable brick 1.

[0057] Please also refer to Figure 1 and Figure 2 Optionally, the first clamping protrusion 12 is located between the first hole wall 100 and the third hole wall 110, and the first clamping recess 13 is located between the second hole wall 101 and the fourth hole wall 111. This arrangement can avoid the first through hole 10 and the second through hole 11 being too close, preventing concrete from entering the second through hole 11 or preventing sponge from entering the first through hole 10.

[0058] like Figure 1As shown, a second snap-in protrusion 14 can be provided on the front short side of the permeable brick 1, and a second snap-in recess 15 can be provided on the rear short side of the permeable brick 1. When adjacent permeable bricks 1 are laid, the second snap-in protrusion 14 of one permeable brick 1 and the second snap-in recess 15 of another adjacent permeable brick 1 can snap-in with each other. The diameters of the second snap-in protrusion 14 and the second snap-in recess 15 can be the same. The second snap-in protrusion 14 can be convex outward along the positive direction parallel to the Y axis, and the second snap-in recess 15 can be concave inward along the positive direction parallel to the Y axis.

[0059] Please also refer to Figures 1 to 3 In another embodiment, a pavement structure 2 is provided, which includes a soil roadbed 20, a crushed stone layer 21, a permeable brick layer 22 and a permeable asphalt layer 23, which are sequentially supported from bottom to top. The permeable brick layer 22 includes a plurality of permeable bricks 1 in the above-mentioned embodiment. The permeable asphalt layer 23 is laid on the permeable brick layer 22 to achieve a rigid-flexible composite effect, thereby improving the walking comfort and service life of the pavement structure 2.

[0060] The paving method of pavement structure 2 is as follows:

[0061] (1) The preparation and maintenance of the water-stable crushed stone layer 21 on the soil roadbed 20 is completed through processes such as paving and leveling;

[0062] (2) paving a permeable brick layer 22 on the gravel layer 21, paving the permeable bricks 1 in the permeable brick layer 22 in the correct position, filling the first through holes 10 in a row between the paved permeable bricks 1 with steel slag permeable concrete, and filling the second through holes 11 in a row between the permeable bricks 1 with sponge material, and performing staggered filling construction;

[0063] (3) During paving, check each permeable brick 1 one by one to ensure that each permeable brick 1 in the permeable brick layer 22 has no damaged edges or corners and no adhesion;

[0064] (4) When the permeable bricks 1 are laid to the roadside and there are gaps, fill them with 1-3 mm steel slag sand or fill the gaps with steel slag mortar;

[0065] (5) After the permeable brick layer 22 is paved, the mixed cold-mixed OGFC permeable asphalt is used to pave the permeable asphalt layer 23. The thickness of the permeable asphalt layer 23 is 40-60 mm, and the permeable asphalt layer 23 is spread, smoothed, corrected and compacted.

[0066] The permeable bricks and pavement structures provided by the embodiments of the present application are described in detail above. For those skilled in the art, according to the ideas of the embodiments of the present application, there will be some changes in the specific implementation methods and application scope.
