Composite water-permeable brick plate with prefabricated surface layer, and preparation method thereof

Abstract

The invention discloses a composite water-permeable brick plate with a prefabricated surface layer, and a preparation method thereof, and belongs to the technical field of composite water permeable brick plates. The composite water-permeable brick plate comprises a prefabricated surface layer and a water-permeable base layer which are bonded up and down. The prefabricated surface layer is a pre-customized soft stone or argil pavement laying plate; the water-permeable base layer is of a water-permeable or semi-water-permeable concrete module structure formed by compounding mud and a prefabricated surface layer; the periphery of the top surface of the water-permeable base layer protrudes upwards to form a coating edge; the coating edge is bonded with one part of the peripheral side wall of the prefabricated surface layer; one end of the water-permeable base layer sinks inwards to form a drainage groove; a water storage tank is formed in the middle of an inner cavity of the water-permeable base layer in the length direction; and a water seepage groove is formed in the bottom of an inner cavity of the water-permeable base layer in the length direction. According to the composite water-permeable brick plate with the prefabricated surface layer, and the preparation method thereof, external force scratching friction can be borne, the attractiveness of the water-permeable brick can bebetter improved, and the phenomenon that the water-permeable brick is broken or the other side of the water-permeable brick tilts up can be better prevented.

Description

technical field [0001] The invention relates to the technical field of composite permeable brick panels, in particular to a composite permeable brick panel with a prefabricated surface layer and a preparation method thereof. Background technique [0002] At present, the permeable paving of urban roads is made of semi-dry concrete permeable bricks formed by pressing and vibrating with brick machines. The traditional manufacturing process is divided into coarse-grain base materials and fine-grain surface materials with different concrete gradations. Extrusion molding, because there are many problems in the practical application of this permeable brick, technical personnel in the professional field have made corresponding improvements. [0003] as attached figure 1 and 2 As shown, the existing improved composite pavement permeable brick consists of two parts: the surface layer a and the base layer b. Among them, in order to prevent weathering and delamination and aesthetic ef...

Problems solved by technology

[0004] 1. For the composite permeable brick, since the surface layer a and the base layer b are solidified and formed by using different formulations of mud raw materials through the mold, and the base layer b is prefabricated during preparation, and the surface layer a is laid on the top of the base layer b after the base layer b is solidified and formed. Therefore, this preparation process is only applicable to permeable bricks with non-hard and smooth surface layer a, which lacks durability, and the pattern, color and texture of the surface layer a after forming are relatively single, and lack aesthetics;

[0005] 2. Since the texture of the surface layer a is relatively solid, and the base layer b is a structural layer with gaps, when the permeable brick is subjected to unbalanced force F on one side corner for a long time, the base layer b will have different degrees of settlement and shrinkage, which will cause the surface layer a The support structure is lost at the bottom of the stressed corner, resulting in corner breakage;

[0006] 3. Based on the defect described in 2., after the surface layer a settles and shrinks on the base layer b and loses the support structure, if there is no corner breakage due to its good strength and reliability, it is easy to produce a dislocation at the opposite corner of the stress point. The base layer b is separated from the leverage force, which causes the surface layer a to lift and detach at the opposite corner of the force point
