Technical Field

The invention relates to the technical field of building materials, in particular to a brick structure for paving a road surface.

Background

When ordinary pavement bricks are paved, mortar needs to be used for bonding, pointing and maintaining, the construction period is long, and the process is complicated. After the road surface water seeping device is put into use, inconvenience is caused, the road surface runoff is large in rainy seasons, the road surface is wet and slippery, drainage is not smooth, the phenomenon of water seeping on the road surface is serious, and the water seeping disaster and the like are easily formed to influence the traveling and property safety of residents. And because the paving adopts a tiling method, the surface bearing force is determined by the size of the face brick and the stability of the foundation, the bearing capacity of the pavement is limited, and the quality and the service life of the pavement are further reduced after the stability of the base layer is weakened by rain erosion, so that municipal works need to invest a large amount of funds to maintain urban street footpaths every year.

Water permeable bricks have a porous surface known as green pavement, which allows water to pass through for the purpose of reducing road run-off. But the installation cost is higher compared with the common pavement bricks. The porous surface is permeable but also prone to clogging, and industrial vacuum devices must be used to remove sand and fine particles that clog the voids. Failure to quickly clear the blockage can result in water and contaminants being lost from the surface, thereby damaging the permeable pavement. Also, the loose porosity reduces the firmness of the pavement, and if the pavement is subjected to excessive pressure, the pavement structure will collapse.

Detailed Description

The invention will be further illustrated by the following examples in conjunction with the accompanying drawings:

as shown in figures 1-6, the bonding-free hydrophobic pavement brick comprises a bottom brick A and a face brick B, both of which are made of solid concrete bricks. Preferably, the bottom brick A and the surface brick B are green solid concrete bricks made of recycled materials.

The bottom brick A is formed by pouring a hexagonal central column 1, a hexagonal conical table 2 and a hexagonal bottom plate 3 which are coaxially arranged from top to bottom in sequence. The regular-hexagonal central column 1 is arranged on the top surface of the regular-hexagonal conical table 2 in the middle, the cross section of the regular-hexagonal central column 1 is smaller than that of the regular-hexagonal conical table 2, and the regular-hexagonal central column 1 is staggered after horizontally rotating for a certain angle relative to the regular-hexagonal conical table 2. The part of the top surface of the regular hexagonal conical platform 2, which is exposed out of the regular hexagonal central column 1, is a pressure bearing surface a for bearing the face brick B, and the face brick B is just covered by the face brick B after installation. The regular hexagonal bottom plate 3 is formed by downward extending of the bottom surface of the regular hexagonal frustum 2, namely the side length of the regular hexagonal bottom plate 3 is consistent with that of the bottom surface of the regular hexagonal frustum 2. The face brick B is a regular hexagonal column and is consistent with the side length and the height of the regular hexagonal central column 1.

When the bottom bricks A are closely laid in a honeycomb manner, six face bricks B are embedded and laid around the periphery of a regular hexagonal central column 1. A face brick B is just embedded and installed among every three regular hexagonal central columns 1 which are arranged in a triangular mode and supported through corresponding three pressure bearing surfaces a, so that the bottom brick A and the face brick B are overlaid in a honeycomb mode and an inner brick pipe network C is formed by the bottom brick A and the face brick B in a surrounding mode. The binding surface of face brick B and regular hexagon center post 1 constitutes leads the surface of water, has seted up water guide chute B on the top edge of regular hexagon toper platform 2 for with the water drainage that flows into pressure-bearing surface a through the water guide surface to the brick inner pipe net C.

Preferably, a water guiding chute b is arranged at the center of each edge at the top of the hexagonal conical table 2, that is, six water guiding chutes b are arranged on each bottom brick a.

Preferably, the side lengths of the regular hexagonal central column 1 and the face brick B are 99mm, and the height of the face brick B is 45 mm; the upper side of the regular hexagonal conical table 2 is 126mm long, the lower side is 173mm long and 45mm high; the side length of the regular hexagonal bottom plate 3 is 173mm, and the height is 10 mm; the width of the water guide chute b is 5 mm.
