Description

Technical Field

[0001] This utility model relates to the field of concrete pavement brick laying technology, specifically to a concrete pavement brick laying structure for preventing settlement. Background Technology

[0002] Concrete paving bricks are a common paving method for urban roads, squares, sidewalks, etc., and have the advantages of being beautiful, durable, permeable, and easy to construct.

[0003] During the laying of concrete paving bricks, factors such as poor drainage, uneven load-bearing capacity, or insufficient load-bearing capacity can easily lead to settlement problems during use, affecting the service life of the paving bricks and increasing maintenance costs. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a concrete paving brick anti-settlement structure to solve the problem of settlement that easily occurs during the use of paving bricks after they are laid, as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete pavement brick paving structure for preventing settlement, comprising a base layer, a permeable mold shell on the top of the base layer, a crushed stone filling layer inside the permeable mold shell, the permeable mold shell having a hexagonal structure when viewed from above, a geotextile on the top of the permeable mold shell, a leveling layer on the top of the geotextile, and permeable bricks on the top of the leveling layer.

[0006] Preferably, the permeable formwork shell is made of recycled PP plastic, and the permeable formwork shell is fixed to the base layer by composite anchoring technology.

[0007] Preferably, a distributed support net is laid on top of the leveling layer, and the width of the distributed support net is smaller than the width of the permeable brick.

[0008] Preferably, the permeable brick has a groove at its bottom, and the distributed support net is located in the groove.

[0009] Preferably, the leveling layer is made of fine sand, and the distributed support mesh is fixed to the leveling layer by concrete.

[0010] Preferably, the permeable bricks are fixed to the top of the dispersed support net by concrete, and the gaps between the permeable bricks in the lateral direction are filled with coarse sand for grouting.

[0011] Preferably, drainage holes are provided on both sides of the permeable membrane shell to promptly drain excess rainwater from inside the permeable membrane shell.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This device can improve drainage performance and make the load distribution more uniform while improving the load capacity of the device, thereby ensuring the service life of the device and reducing the maintenance frequency.

[0014] (2) This device can not only convert vertical load into lateral dispersion force by fixing a permeable mold shell on the top of the compacted base layer and filling the inner hole of the permeable mold shell with a crushed stone filling layer, thus reducing the compaction and settlement of the base layer, but also improve the permeability and prevent water accumulation from softening the base layer by filling the crushed stone filling layer inside the permeable mold shell to form a three-dimensional drainage channel.

[0015] (3) This device opens a groove at the bottom of the permeable brick for connection with the distributed support net. The distributed support net can support the permeable brick, making the pressure more evenly distributed and reducing the problems of loosening and settling of the permeable brick.

[0020] 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.

[0021] Please see Figure 1-3This utility model provides a technical solution: a concrete pavement brick paving structure for preventing settlement, including a base layer 9, with a permeable formwork 6 on top of the base layer 9. The permeable formwork 6 is made of recycled PP plastic. The permeable formwork 6 is fixed to the base layer 9 using composite anchoring technology. Before paving, the base layer 9 needs to be compacted to ensure the stability of the foundation. Drainage holes 7 are provided on both sides of the permeable formwork 6 to promptly drain excess rainwater from inside the permeable formwork 6. This structure is equipped with drainage holes 7... The permeable formwork 6 improves drainage. The interior of the permeable formwork 6 is filled with a gravel layer 8. Viewed from above, the permeable formwork 6 has a hexagonal structure. A geotextile 5 is placed on top of the permeable formwork 6, and a leveling layer 4 is placed on top of the geotextile 5. A distributed support net 3 is laid on top of the leveling layer 4. The width of the distributed support net 3 is smaller than the width of the permeable bricks 1. The leveling layer 4 is made of fine sand. The leveling layer 4 ensures the horizontal and stable laying of the permeable bricks 1. The distributed support net 3 is fixed to the leveling layer 4 with concrete. The structure can distribute the load through the distributed support net 3, and also support the permeable brick 1. The permeable brick 1 is set on the top of the leveling layer 4. The bottom of the permeable brick 1 has a groove, and the distributed support net 3 is located in the groove. This structure can improve the firmness of the connection between the permeable brick 1 and the distributed support net 3. At the same time, the distributed support net 3 will not affect the connection between the permeable brick 1 and the leveling layer 4. The permeable brick 1 is fixed to the top of the distributed support net 3 by concrete. The gaps between the permeable bricks 1 in the horizontal direction are filled with coarse sand 2. The coarse sand 2 in this structure ensures the drainage effect during use. The height of the permeable formwork shell 6 of this device can be controlled between 50-80mm, and the wall thickness is controlled at 2mm. The permeable formwork shell 6 can reduce the amount of crushed stone filling layer 8. At the same time, the permeable formwork shell 6 formed by the "honeycomb" structure can convert the vertical load into lateral distributed force, reducing the compaction settlement of the base layer 9. The permeable formwork shell 6 is filled with crushed stone filling layer 8 to form a three-dimensional drainage channel, which improves the water permeability and prevents water accumulation and softening of the base layer 9.

[0022] Working principle: When using this anti-settlement concrete pavement brick paving structure, firstly, the base layer 9 is compacted using compaction equipment. Then, the permeable formwork 6 is fixed to the base layer 9 using composite anchors. After fixing, the hexagonal holes of the permeable formwork 6 are in a vertical state. Then, the crushed stone filling layer 8 is filled into the hexagonal holes of the permeable formwork 6. Next, geotextile 5 is laid and reinforced with anchor rods. Then, the leveling layer 4 is laid. Then, the distributed support net 3 is fixed to the bottom groove of the permeable brick 1 with concrete. After the distributed support net 3 is fixed, the distributed support net 3 and the permeable brick 1 are fixed to the leveling layer 4 with concrete. Finally, the gaps of the laid permeable brick 1 are filled with coarse sand 2.

[0023] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
