Prefabricated building block

Abstract

The invention relates to the technical field of building materials, in particular to a prefabricated building block. The prefabricated building block comprises a water permeable surface layer and support layers, wherein the support layers are polygonal prisms, the outer contour of the cross section of the support layers is orthohexagnal, and a plurality of first open holes are formed in the support layers and penetrate the upper and lower surfaces of the support layers, accordingly, the water-permeable function can be realized through the first open holes, and the water storage function can be realized by matching with the water-impermeable ground after installation. Rainwater can enter the first open holes in the support layers through the water permeable surface layer to be stored. When the water quantity is small, the stored water can keep a road in a wet state through evaporation, so that the probability of flying dust on the road is low, the specific heat of the road is increased, the surface temperature is reduced, and the heat island effect is relieved. The support layers are polygonal prisms, and the outer contour of the cross section of the support layers is orthohexagnal, so that when the road is assembled, tightness between the supporting layers is high, flatness is higher, the problem of uneven settlement of a foundation can be effectively solved, and the structure stability is maintained.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an assembled block. Background technique [0002] At present, in urbanization construction, due to the weak water permeability of traditional asphalt and concrete pavement, it is difficult for rainwater to permeate when it rains, which will cause the road to accumulate water. It also affects the groundwater recharge. [0003] In view of the above problems, a permeable surface layer in the prior art includes a permeable surface layer and a support structure located below the permeable surface layer, wherein the permeable surface layer is made of silica sand in the desert through special processing, and the support structure is made of permeable concrete. When it rains, the accumulated water infiltrates below through the permeable gaps on the permeable surface, and then the water flow infiltrates into the soil or drainage system through the permeable function of the ...
