Water-permeable brick plate with composite surface layer and for road surface as well as preparation method thereof

Abstract

The invention relates to a water-permeable brick plate with a composite surface layer and for a road surface. The water-permeable brick plate with the composite surface layer and for the road surfacecomprises a brick body; at least two upper grooves which extend in the longitudinal direction and with upward notches are formed in the upper side surface of the brick body; the transverse size of thegroove bottom of the cross section of each upper groove is larger than the transverse size of the notch; when the quantity of the upper grooves is more than two, the upper grooves are distributed inthe transverse direction sequentially at intervals; the water-permeable brick plate with the composite surface layer and for the road surface further comprises a water-permeable material layer which is paved on the upper side surface of the brick body and is added to the upper groove; a water-permeable channel capable of communicating from top to bottom is formed in the brick body. According to the brick plate, a rich surface layer can be designed according to the requirement, and the surface layer of the brick body has rich colors and has high harmony with the surrounding environment. The comfortability is high, and the walking comfortability can be enhanced when the surface layer material is a soft material. The surface layer material can adopt a regenerated material, and resource recycling of the surface layer material can be improved completely.

Description

technical field [0001] The invention relates to the field of road construction, in particular to a permeable brick board for pavement with a composite surface layer and a preparation method thereof. Background technique [0002] At present, the permeable pavement of urban roads adopts semi-dry concrete permeable bricks formed by pressing and vibrating with brick machines. The traditional manufacturing process is divided into coarse-grained base materials and fine-grained surface materials with different concrete gradations. Extrusion molding; this kind of permeable brick has the following problems: 1. The bonding between the base layer and the surface layer of the permeable brick is affected by external friction and the heat shrinkage ratio of each layer of material, and external environmental factors corrode, forming surface layer particles Shedding and weathering delamination, resulting in serious pavement color difference and surface pollution (such as Figure 12 , shown ...

[0002] At present, the permeable pavement of urban roads adopts semi-dry concrete permeable bricks formed by pressing and vibrating with brick machines. The traditional manufacturing process is divided into coarse-grained base materials and fine-grained surface materials with different concrete gradations. Extrusion molding; this kind of permeable brick has the following problems: 1. The bonding between the base layer and the surface layer of the permeable brick is affected by external friction and the heat shrinkage ratio of each layer of material, and external environmental factors corrode, forming surface layer particles Shedding and weathering delamination, resulting in serious pavement color difference and surface pollution (such as Figure 12 , shown in 13); 2. Through this extrusion molding process, the surface material must be hard and pressure-resistant, which limits the use of the surface material that makes the feet feel comfortable and soft, durable in color, and good in water permeability; 3. Due to The permeable mechanism of the permeable brick manufactured by this traditional process is to permeate water through the tiny pores of the brick body. Due to the dust, organic matter, and fine sand particles in the external environment, the pores of the permeable brick are blocked, and the permeable function is basically lost in a short time. The pavement surface Layers are hardened, losing the function of rainwater infiltration and evaporation, causing noise reflection on the paved road surface and pollution results in environmental ecology being destroyed
