Description

Technical Field

[0001] This utility model relates to the field of permeable brick technology, and in particular to a permeable brick with stepped gaps. Background Technology

[0002] Most existing permeable bricks are made entirely of permeable material, allowing rainwater to be filtered through the material before entering the water storage channel, which is costly. If the brick body is made of non-permeable material, water can only be permeated through drainage gaps. However, impurities such as silt can easily enter the water storage channel through these gaps, causing blockages and reducing the lifespan of the permeable bricks. Furthermore, water accumulation is more likely to occur on roads paved with permeable bricks. Utility Model Content

[0003] This utility model proposes a permeable brick with stepped gaps. The permeable brick is made of non-permeable material, which reduces costs. Moreover, the rainwater is filtered through the filter material in the stepped gaps, preventing impurities such as silt from entering the water storage channel, and also preventing the filter material from entering the water storage channel.

[0004] The technical solution of this utility model is implemented as follows: a permeable brick with stepped gaps includes a non-permeable brick body. The bottom of the non-permeable brick body is provided with a through water storage channel. A water collection trough is provided on the periphery of the upper end of the non-permeable brick body. Vertical stepped grooves are provided on the side wall of the non-permeable brick body. The water collection trough is connected to the water storage channel through the stepped grooves. The stepped grooves of adjacent non-permeable brick bodies form a stepped gap. The horizontal gap at the upper part of the stepped gap is larger than that at the lower part. The upper part of the stepped gap is filled with filter material.

[0005] Furthermore, a stepped groove is provided around the perimeter of the non-permeable brick, and a spacer protrusion is provided at the bottom of the stepped groove. The spacer protrusions on the opposite sidewalls of the non-permeable brick are staggered. The spacer protrusions abut against the bottom of the stepped groove of the adjacent non-permeable brick and form the bottom of the stepped gap.

[0006] Furthermore, the non-permeable bricks are provided with stepped grooves at intervals along their perimeter. The horizontal gap at the top of the stepped grooves is larger than that at the bottom. The stepped grooves are provided one-to-one with the ends of the water storage channels. The stepped grooves of adjacent non-permeable bricks are aligned to form stepped gaps.

[0007] Furthermore, the water storage channel includes a horizontal channel and a vertical channel, which are interconnected and both horizontally penetrate the impermeable brick body.

[0008] Furthermore, it also includes a permeable cushion layer laid on the ground, with the bottom of the non-permeable bricks bonded to the permeable cushion layer.

[0009] Furthermore, the water storage channel is an arched channel.

[0010] Furthermore, the non-permeable bricks are rectangular bricks.

[0011] Furthermore, the filter material is filter sand.

[0012] The beneficial effects of this utility model are:

[0013] The permeable brick of this utility model is made of non-permeable material, which reduces costs. Moreover, it forms a stepped gap through stepped grooves. The upper part of the stepped gap is filled with filter material, which filters rainwater and prevents impurities such as silt from entering the water storage channel. At the same time, the horizontal gap at the upper part of the stepped gap is larger than that at the lower part, which prevents the filter material from entering the lower part of the stepped gap, thereby preventing the filter material from entering the water storage channel.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] like Figure 1-6 As shown, a permeable brick with stepped gaps includes a non-permeable brick body 1, which is a rectangular brick body and includes a base layer 2. The upper side of the base layer 2 is a surface layer 3. Both the base layer 2 and the surface layer 3 are made of non-permeable materials. A water storage channel is provided at the bottom of the non-permeable brick body 1. The water storage channel includes a transverse channel 4 and a longitudinal channel 5. The transverse channel 4 and the longitudinal channel 5 are connected, such that a longitudinal channel 5 passes through the middle of the two transverse channels 4.

[0029] A water-collecting groove 6 is provided around the upper periphery of the non-permeable brick body 1, and a vertical stepped groove 7 is provided around the periphery of the non-permeable brick body 1. The stepped grooves 7 of adjacent non-permeable brick bodies 1 form a stepped gap 8. A spacer protrusion 9 is fixed at the lower part of the stepped groove 7. The spacer protrusions 9 on opposite sidewalls of the non-permeable brick body 1 are staggered. The spacer protrusions 9 abut against the lower part of the stepped groove 7 of adjacent non-permeable brick bodies 1, forming the lower part of the stepped gap 8.

[0030] like Figure 5 As shown, the horizontal gap at the top of the stepped gap 8 is larger than that at the bottom. For example, the upper horizontal gap is 4.5mm and the lower horizontal gap is 1.5mm. The upper part of the stepped gap 8 is filled with filter material 10, which is filter sand. Because the lower gap is smaller, the filter sand will only fill the upper part of the stepped gap 8, preventing the filter sand from entering the water storage channel through the lower part of the stepped gap 8. The water collection tank 6 is connected to the water storage channel through the stepped gap 8.

[0031] The method of using the permeable bricks is as follows: Figure 4-6 As shown, a permeable cushion layer 11 is laid on the ground. The permeable cushion layer 11 is a permeable concrete layer. Then, the bottom of the permeable bricks is bonded to the permeable cushion layer 11 using an adhesive layer 12. The adhesive layer 12 is cement mortar and avoids the water storage channel.

[0032] The impermeable bricks 1 are arranged one by one, with the ends of the transverse channels 4 of adjacent impermeable bricks 1 connected and the ends of the longitudinal channels 5 connected. The interval protrusions 9 abut against the lower part of the stepped grooves 7 of adjacent impermeable bricks 1. The stepped grooves 7 of adjacent impermeable bricks 1 are aligned to form stepped gaps 8. The stepped gaps 8 are filled with filter material 10. Rainwater enters the upper part of the stepped gaps 8 through the water collection trough 6, and then enters the lower part of the stepped gaps 8 after being filtered by the filter material 10. Finally, it enters the permeable cushion layer 11 through the water storage channel and seeps into the ground surface.

[0033] Example 2

[0034] This embodiment is basically the same as Embodiment 1, except that, as Figure 7-10 As shown, the non-permeable brick body 1 is provided with stepped grooves 7 at intervals along its perimeter. The horizontal gap at the upper part of the stepped groove 7 is larger than that at the lower part. The stepped grooves 7 are provided one-to-one with the ends of the water storage channel. The stepped grooves 7 of adjacent non-permeable brick bodies 1 are aligned to form stepped gaps 8. The upper gap of the stepped gap 8 is 8mm and the lower gap is 1.5mm.

[0035] Non-permeable bricks 1 are laid in alignment, with their sidewalls abutting each other. The stepped grooves 7 of adjacent non-permeable bricks 1 are aligned to form stepped gaps 8, and filter material 10 is filled into the stepped gaps 8.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
