Abstract

The utility model discloses a grass-planting paving brick which belongs to the technical field of the science and technology of environmental protection. The utility model solves the technical problem that green grass can grow in afforestation areas of cities, in green enlarging squares, among street trees and in green belts where people can walk, play and park vehicles, purifying environment and widening the afforestation areas of cities. The utility model has the main technical characteristic that square hole plates with circular holes and rectangular strip holes are made by adopting composite material to be shaped by pressing through a steel mold. The peripheries of the adjacent grass-planting paving bricks are adhesively connected by cement mortar and cultivating soil is put into the holes to form a grass-planting ground. The utility model is suitable for building green lawns in squares, slopes, street trees and architectural buildings.

Description

Ground brick for planting grass

Ground brick for planting grass belongs to the environmental protection science technical field.

The city-building develop rapidly of China at present, only see that group building stands in great numbers, and the vacant lot between the group building, concrete plate commonly used covers, general square is watered concrete plate surface more or is made the grinding stone face, also plates of spreading concrete between the avenue tree on sidewalk more, the green scene in the living space in cities and towns is reduced, side slope, protecting of riverbank at railway and highway are put forward side slope, all adopt concrete or stone to build block, can not grow grass, destroyed the ecological homeostasis, on the side slope face, will establish spilled water hole, expend a large amount of concrete and stone material, and commercially available floor tile does not possess the grass planting function at present.

The purpose of this utility model: increase the green scene in the living space in cities and towns, beautify town environment, ad hoc meter exploitation Ground brick for planting grass had both possessed the grass planting function, possessed the load-carrying function again.Be applicable to afforestation of city, extend between green square, avenue tree and the green belt of side slope is constructed, the green grass of can both growing, the people can walk in the above and play, and vehicle can be parked in the above, and not only environment purification but also the greening face of widening can be protected the ecological homeostasis effectively.

Ground brick for planting grass: one, make and have center hole (1), four limits are semicircle orifice (2) and four square orifice plates that the diagonal angle is quadrant hole (3), the thickness of orifice plate (4) is made up of skin layer composite material (5) and bearing course composite material (6), through punching block compression moulding; They are two years old, make the rectangle cylindrical void (7) with two ends semicircle, rectangle cylindrical void (8),  two ends semicircle rectangle cylindrical voids (9) and four square orifice plates that the diagonal angle is  two ends semicircle rectangle cylindrical voids (10) of an end semicircle, the thickness of orifice plate (11) is made up of skin layer composite material (12) and bearing course composite material (13), through punching block compression moulding.

The top layer of Ground brick for planting grass is by cementitious materials, color pigment, water, polypropylene fibre, form skin layer composite material (5) and (12) through mix, its proportioning is: cementitious materials: shades of colour pigment: water: polypropylene fibre=1: 0.2: 0.2: (0.0015～0.002).The bearing course of Ground brick for planting grass is by steel fibre, cementitious materials, high-strength aggregate, special fine powder, high efficiency water reducing agent, form bearing course composite material (6) and (13) through mix, its proportioning is: cementitious materials and special fine powder: high-strength aggregate: high efficiency water reducing agent: water: steel fibre=1: (3.32～3.38): (0.02～0.022): (0.15～0.20): (0.20～0.25).

The making of Ground brick for planting grass and use are all simpler, at smooth solid face upper berth, base one deck sand, on layer of sand, lay Ground brick for planting grass, in the hole, add and cultivate native grass planting or plant undershrub, and with company's seam crossing of the adjacent surrounding of Ground brick for planting grass, bonding with cement mortar, can the bonding green belt that is assembled into required area size.

This product material therefor: cementitious materials is high-strength cement or spherical cement, and aggregate is granite and limestone, and granularity is 0.5～10 millimeter, and high efficiency water reducing agent is commercially available industrial chemicals, and special fine powder is silica flour and fine coal ashes.

Advantage of the present utility model and effect:

1. have the grass planting function, cultivate the soil grass planting or plant undershrub but in circular hole and rectangle cylindrical void, add;

2. have bearing function, adopt composite material to make Ground brick for planting grass, have the mechanical property that bearing automobile is parked, because of Ground brick for planting grass has certain thickness, unlikely damage grass roots;

3. can extend effectively between green square, avenue tree and the green belt of side slope is constructed, not only environment purification but also widen green face;

4. lay Ground brick for planting grass in side slope, can not establish spilled water hole, the effect that grass of being planted or undershrub play fixed slope simultaneously and beautify the environment;

5. making is simple, the construction period is short, cost is low.
