Abstract

A permeable paving brick of cement and fine crushed stone is essentially used for paving a walkway, a greening way of park and a swimming pool. The permeable paving brick is made of the fine crushed stone, the cement, a binder and a little of water by pressing through a dry stirring. The brick comprises a body which is equipped with a facing layer which is composed of the fine crushed stone, the cement, the binder and a colourant; the brick also comprises a base course which is composed of the fine crushed stone, the cement and the binder. The body has a gap by which the water can penetrate into a ground layer below the body to be absorbed; a lateral of the body is equipped with a raised block. The fine crushed stone is mainly made of crushed granite by machining. The utility model is characterized in well permeability, convenient construction, pleasant appearance and waster reutilization.

Description

The permeable paving brick of cement fine stone

(1) technical field

The utility model relates to building material field, is specifically related to the permeable paving brick of a kind of cement fine stone, mainly is applicable to the ground in places such as laying sidewalk, park irrigation road, swimming hall.

(2) background technology

At present, the ground in places such as the sidewalk of urban operating mechanism, park irrigation road, swimming hall, generally adopting granite plates, ceramic tile is that facing is laid.Because face brick will adopt cement mortar to lay, do not seep water, if rainy day, road-face water-collecting, the generation road is slided and is dabbled and makes passerby be difficult to walking; If the ground around swimming pool, its road surface is sliding, more is difficult to walking.

(3) summary of the invention

The purpose of this utility model is the needs according to the field of employment, has designed the permeable paving brick of a kind of cement fine stone, has water permeability preferably.

The purpose of this utility model is realized by following technical scheme: the permeable paving brick of cement fine stone, adding low amounts of water dryness stirring compacting by fine stone, cement, binding material forms, the finish coat of brick body is fine stone, cement, binding material and colorant, basic unit is fine stone, cement and binding material, the brick body is formed with the slit, water can be penetrated into the formation absorption of brick body below from the slit, is laid with projection in the side of brick body, makes that adjacent two brick bodies leave the shrinkage joint automatically when laying.The fine stone granite stones that mainly has drawn from forms through machining.

The permeable paving brick of cement fine stone provided by the utility model can utilize granite barren rock material to be made, and has good water permeability.During laying,, on sand bed, spread the permeable paving brick of cement fine stone and get final product as long as at cement concrete roadbed upper berth last layer sand.According to the field of employment, the roadbed that suits should be selected in the ground under the sand bed.Characteristics with good water permeability, easy construction, attractive in appearance, refuse reclamation.

(5) specific embodiment

Embodiment: present embodiment adds low amounts of water dryness stirring compacting by fine stone, cement, binding material and forms, and the finish coat of brick body (1) is fine stone, cement, binding material and colorant, and basic unit (2) is fine stone, cement and binding material, and the brick body is formed with the slit.Be laid with projection (3) in the side of brick body, each limit of brick body is provided with two projections (3), (4), and the projection on each limit is partial to same edge, makes that the projection of adjacent two brick bodies all staggers mutually arbitrarily, its break joint that forms automatically is exactly the thickness of projection, and it is very convenient to construct.The fine stone granite stones that has drawn from forms through machining.

Claims (2)

1, the permeable paving brick of cement fine stone, it is characterized in that adding low amounts of water dryness stirring compacting by fine stone, cement, binding material forms, the finish coat of brick body is fine stone, cement, binding material and colorant, basic unit is fine stone, cement and binding material, the brick body is formed with the slit, is laid with projection in the side of brick body.

2, according to the permeable paving brick of the described cement fine stone of claim 1, it is characterized in that the projection on each limit of brick body is partial to same edge.
