Problems solved by technology

With the continuous increase of the urban population and the continuous expansion of the construction area, most of the land will be closed by road squares paved with water-blocking materials such as urban buildings and cement, so that precious natural precipitation cannot penetrate into the soil, and the increasingly depleted groundwater resources will be recovered. If it is not timely to make up for it, it will also increase the load on the municipal drainage system, restricting the sustainable development of urban construction

Embodiment 1

[0029] Such as figure 1 As shown, the permeable floor tile of the present invention is sintered from spontaneously combusted coal gangue granules, and there are three-dimensional through pores 2 between the granules 1 . The brick body has a two-layer pore diameter gradient structure from the surface to the bottom surface. The particle size of the surface layer particles is 1-2 mm; the particle size of the bottom layer particles is 3-4 mm.

[0030] Preparation method: It is obtained through material selection, granulation, screening and selection of granules, adding binder and mixing, molding and firing. The weight percentage of the binder A used is: 35% of albite feldspar, 25% of window glass powder, and 40% of kaolin; the binder B is water glass with a modulus of 2-4. Binder A is pulverized by ball milling into a fine powder with a residue of less than 3% on a 10,000-hole sieve for later use.

[0031] Binders are added to the large and small granules respectively, and the w...

Embodiment 2

[0036] The water-permeable floor tile of the present invention is formed by sintering Zibo cooked coke gem granules, and there are three-dimensional through holes between the granules, and the particle diameter of the granules is 0.5-2mm.

[0037] Preparation method: It is obtained through material selection, granulation, screening and selection of granules, adding binder and mixing, molding and firing. The weight percentage of the binder A used is: 33% of potassium feldspar, 28% of window glass powder, and 39% of Laiyang soil; the binder B is water glass with a modulus of 2-4. Binder A is pulverized by ball milling into a fine powder with a residue of less than 3% on a 10,000-hole sieve for later use.

[0038] The weight composition of the granular material batching is: 86% of the granular material, 14% of the binder A; 8% of the binder B is added.

[0039] After adding the binder, the mixture is aged for 28 hours and then pressure-formed.

[0040] The molded product is dri...

Abstract

A water-permeable ground brick containing 3D through gaps is made up through choosing raw materials, granulating, screening, mixing with binder, shaping and sintering. Its advantages are high water permeability, low cost, and high antiskid and antiwear performance.

Description

technical field [0001] The invention provides a water seepage floor tile and a preparation method thereof, belonging to the technical field of building materials. Background technique [0002] On the one hand, in nature, rainwater should naturally seep through the surface and into the ground. But at present, the paving materials of urban roads and squares, such as traditional water-blocking materials such as cement block bricks, ordinary ceramic sintered bricks, concrete pavement, asphalt pavement, and the interception of urban buildings together block the infiltration of natural precipitation through the surface. Underground, coupled with the city's long-term over-exploitation and successive years of drought, urban groundwater resources have declined year by year, and groundwater levels have dropped sharply. Large underground funnel groups have formed in Beijing, Tianjin, Shijiazhuang and other places in my country. For example, the world-famous ...
