Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a water permeable brick technical field, specifically relates to a sidewalk water permeable brick. BACKGROUND
[0002] At present, when the sidewalk, square and other public open places are constructed in the city, in order to solve the problem of rainwater or poor drainage, the water permeable brick is usually used as the ground material of these open places. When it rains, the rainwater on the open ground penetrates into the water permeable brick. Before laying the water permeable brick, the cement stone (stone) stable layer, concrete cushion or sand cushion is laid on the roadbed.
[0003] In some rainy areas, the road surface is often washed by rainwater, and the rainwater penetrates through the water permeable brick to the bottom. Long-term penetration and water accumulation cause the cushion at the bottom of the water permeable brick to gradually form a cavity, and after being extruded by the upper heavy object such as a battery car, the cavity is enlarged and even collapses. After the rain, when walking on the sidewalk paved with the water permeable brick, the pedestrian may accidentally step on the collapsed water permeable brick at the bottom, and the water permeable brick will extrude and splash the temporarily stored water in the collapsed area, causing the pedestrian to have a bad experience of wet clothes. SUMMARY
[0004] Based on the above description, the utility model provides a sidewalk water permeable brick to solve the problem mentioned in the background technology.
[0005] The technical scheme for solving the above technical problem is as follows:
[0006] A sidewalk water permeable brick comprises a rectangular brick body and a positioning block, a limiting groove is formed in the top surface of the four corners of the brick body, and the positioning block is inserted into the limiting groove of the four brick bodies to form fixation after the four brick bodies are spliced.
[0007] On the basis of the above technical scheme, the utility model can also be improved as follows.
[0008] Further, the bottom of the brick body is provided with a cross-shaped through groove.
[0009] Further, the through groove forms a narrowing opening on one side close to the end surface of the brick body.
[0010] Further, the vertical edge line of the four corners of the brick body forms a rounded corner, and the outer edge line of the bottom surface of the brick body forms a folded edge.
[0011] Further, the positioning block is a pie-shaped structure with an outer circle and an inner circle.
[0012] Further, the positioning block is a pie-shaped structure with an outer circle and an inner square.

[0030] As Figures 1-4 A kind of sidewalk water permeable brick, including rectangular brick 1 and positioning block 2 splicing complete paving, the top surface of the four corners of brick 1 is provided with limiting groove 3, when four bricks 1 are spliced, the limiting groove 3 of four bricks 1 is communicated, form the groove structure matched with the shape of positioning block 2, positioning block 2 is inserted in the limiting groove 3 of four bricks 1 and locks four bricks 1. Brick 1 is preferably square structure.
[0031] When a large area is paved, one corner of each brick body 1 is locked with three adjacent brick bodies 1, that is, each brick body 1 is locked with a surrounding circle of eight brick bodies 1, and as the paving proceeds, the water permeable bricks form a whole. Even if the bottom of the water permeable bricks has a partial pit, when a pedestrian steps on the corresponding water permeable bricks, the water permeable bricks will be fixed by the clamping effect of the surrounding water permeable bricks to support the pedestrian and avoid collapse.
[0032] The positioning block 2 can simultaneously fix the limiting grooves 3 of four spliced brick bodies 1, and therefore the shape of the positioning block 2 is not limited, and the following embodiments are provided in the present scheme.
[0033] The positioning block 2 is a pie-shaped structure with an outer circle and an inner circle, as shown in Figure 1 .
[0034] The positioning block 2 is a pie-shaped structure with an outer circle and an inner square.
[0035] The positioning block 2 is a pie-shaped structure with an outer square and an inner circle, as shown in Figure 2 .
[0036] The positioning block 2 is a pie-shaped structure with an outer square and an inner square.
[0037] In order to avoid the problem of insufficient structural strength of the limiting groove 3 of the brick body 1 caused by the excessive thickness of the positioning block 2, and to avoid the problem of insufficient structural strength of the positioning block 2 itself caused by the excessive thinness of the positioning block 2, the thickness ratio of the positioning block 2 to the brick body 1 is designed to be 1:2 to 1:3.
[0038] The present scheme is more suitable for scenes with large amount of rain, and accordingly, a large amount of rain will cause drainage problems, and excessive short-time rainfall will cause waterlogging caused by insufficient drainage efficiency of the water permeable bricks. In order to improve the drainage efficiency, a cross-shaped through groove 4 is arranged at the bottom of the brick body 1. When the brick bodies 1 are spliced with each other, the through grooves 4 are connected with each other, and the rainwater penetrates from the inside of the brick body 1 and from the gap between the brick bodies 1, both of which enter the through groove 4, and the through groove 4 forms a four-way and eight-way drainage channel and finally flows into the sewer.
[0039] In order to further improve the drainage efficiency, in some embodiments, a round corner 6 is formed at the vertical edge line of each corner of the brick body 1, and a folded edge 7 is formed at the outer edge line of the bottom surface of the brick body 1. The design of the round corner 6 of the vertical edge can make the joint of the four brick bodies 1 larger, facilitating the downward drainage into the through groove 4, and at the same time, the formation of the folded edge 7 at the bottom edge can make the space at the joint larger, facilitating short-time water storage. Accordingly, the through groove 4 forms a narrowing opening 5 from the outside to the inside at the side close to the end face of the brick body 1, and also in order to improve the water storage space and provide a larger receiving capacity for the drainage channel.
[0040] Specifically, the brick body 1 includes an upper wear-resistant layer 8 and a lower water permeable layer 9, and the thickness ratio of the wear-resistant layer 8 to the water permeable layer 9 is 1:10 to 1:15.
[0041] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
