Problems solved by technology

[0004] After a long period of development, many improvements have been made in the structure and materials of permeable bricks. At present, most of the common permeable bricks on the road are made of crushed stones as raw materials with cement and adhesive admixtures. The manufacture of this permeable brick The cost is relatively low, and it has good strength, but its water permeability, wear resistance and anti-skid performance are still unsatisfactory

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...

Abstract

The invention belongs to the field of road engineering materials, and particularly relates to a composite water permeable brick and a preparation method thereof. The provided water permeable brick comprises a concrete slab body layer, a bonding layer and a flexible wearing layer which are in contact successively, the flexible wearing layer is prepared from an organic cementing material and a grading gravel mixed material, the organic cementing material is prepared from modified bitumen and / or a modified polymer, and the grading gravel mixed material is prepared from the following components inparts by weight: 12-26 parts of 1-3 mm of gravels, 35-90 parts of 3-5 mm of gravels, 0-30 parts of 5-10 mm of gravels, 0-20 parts of 10-16 mm of gravels, 0-3 parts of cement, and 0-4 parts of a pigment. The provided composite water permeable brick is formed by the rigid concrete layer and the flexible wearing layer, and has the advantages of water permeability, wear resistance, skid resistance, high strength and the like, these advantages can solve quality problems of freeze-thaw damage, peeling, corroding, swelling, soaking corrosion by rainwater and snowmelt and the like of an existing pavement brick; the service life of the pavement brick is prolonged.

Description

technical field [0001] The invention belongs to the field of road engineering materials, in particular to a composite permeable brick and a preparation method thereof. Background technique [0002] With the development of my country's economy and the acceleration of urban construction, the surface of modern cities is gradually covered by buildings and concrete pavement. Convenient transportation facilities and paved roads bring great convenience to people's travel, but these impermeable roads also bring many negative effects to the ecological environment of the city. Therefore, to alleviate the above problems, people have developed permeable bricks. [0003] Permeable bricks originated in the Netherlands. During the process of building the city from the sea, the Dutch found that the ground after the sea water was drained would cause continuous land subsidence due to long-term lack of contact with water. Once the dykes on the coastline are washed away, the seawater will qui...
