preparation example Construction
[0049] The present invention also provides a method for preparing the above-mentioned composite permeable brick, comprising the following steps:
[0050] a) providing a concrete slab body layer, on which a layer of bonding layer material is arranged;
[0051] b) A layer of flexible wear layer material is placed on the bonding layer material, and cured to obtain a composite permeable brick.
[0052] In the preparation method provided by the present invention, a concrete slab body layer is firstly provided. The preparation method of the concrete slab body layer is not particularly limited in the present invention, and it can be prepared by conventional prefabrication or stamping forming methods.
[0053]After the concrete slab body layer is obtained, a layer of adhesive layer material is arranged on the concrete slab body layer, preferably by spraying or brushing the adhesive layer material on the concrete slab body layer. Generally, the bonding layer material can be set after...
