Grass planting bricks are used as parking spaces and driveways in parking lots. In order to solve the problem of grass roots being crushed by vehicles entering and leaving, grass planting areas are turned into landscape devices in loadable areas. Grass planting brick belongs to concrete brick, which is commonly used in landscape. Grass planting bricks are made of high-quality materials such as concrete, river sand and pigment by vibrating and pressing with a high-pressure brick machine. They are completely unburned and meet the requirements of environmental protection production. At the same time, it uses brick joints or brick holes as grass growing spaces, and the roots of green grass grow under the grass planting bricks to protect the grass roots from damage, so the grass planting bricks have been widely used. It can not only facilitate people's travel, but also increase the green area of the city, thereby improving the environment.
Applicable scenarios
Square, college, parking lot, community greening, park, family courtyard and other places are suitable for paving grass planting bricks.
Grass planting bricks are widely used in the laying of small parks and small parking lots in cities and many units. Grass planting grids turn the grass planting area into a load-bearing surface, which is suitable for parking lots, sidewalks, access roads, fire fighting passages, etc., especially suitable for parking lots and vehicle access roads located in various residential quarters, office buildings, development zones, as well as around sports grounds Temporary parking lots will be built on the campsite and lawn.
Performance and characteristics
At present, Cement grass planting brick The application of grass planting brick is more and more common, because grass planting brick has the advantages of compression resistance, environmental protection and environmental purification.
Here are some characteristics of grass planting bricks:
(1) Extremely strong compression resistance: the pavement has good stability on the ground, and there is no problem for passers-by and drivers. Grass planting bricks have good environmental benefits. They are used to pave the load for greening. The greening rate can reach 30%, and can avoid grass roots being rolled, greatly improving the microenvironment.
It is beneficial to the growth of flowers. The permeability of grass tiles is beneficial to the infiltration of rainwater, and promotes the growth and development of trees, flowers, grass roots, leaves, flowers and fruit stems, without affecting the growth of stuffy roots.
(2) The quality of grass planting brick is good: solid and durable, the service life can exceed 20 years, and it will not fade in harsh environments. Because the grass planting brick is small in size, its bending strength is very high, and its adaptability to the basic uneven settlement is strong. Grass planting bricks have strong resistance to high temperature and freezing thawing. The grass planting bricks are vibrated on six sides with high frequency. The stones are evenly distributed and the surface is rough, so the surface is not easy to be damaged, and the wear resistance and impact resistance are good.
(3) Beautiful and decorative: concrete with green grass makes the environment more close to modern life, harmonious and pleasant, promotes urban greening, meets the basic requirements of urban homestead intensification, and is one of the basic factors to reasonably reduce the cost of commercial housing.
Grass planting bricks can be made into various specifications and colors according to the requirements, and can be assembled into different patterns when laying. Reduce the dazzling condition caused by pavement reflection, reduce the reflection of ground radiation, and reduce the transmission of hot gas on the pavement layer.
(4) The road paved with grass bricks is a flexible road formed by independent small floor tiles, which can move freely without gaps under the influence of load. Grass planting bricks have low requirements for the foundation, and any form of old ground can be used as the basis. The thickness is determined according to the ground load and foundation soil performance. Grass planting bricks can be used on any foundation as long as the foundation can be fully compacted.
Moreover, the cement grass planting bricks are easy to rectify, the grass ceramic bricks are easy to dismantle and lay, and the rectification and renovation of underground pipelines and parking lots are convenient, saving manpower, material resources and funds.
(5) To improve the ecological environment, the gap of the grass tile has a strong air permeability, which is conducive to planting lawn. It can also better store the surface humidity, increase the air humidity, reduce the yellow sand in the sky, purify the air, and improve the urban ecological environment.
Product process and classification
The types of grass planting bricks are as follows:
(1) According to its hole shape, it can be divided into round holes, round holes or other hole shapes. The shapes of the grass planting brick products in the market generally have a zigzag shape, a vest shape, a single 8-shaped shape, a double 8-shaped shape, and a grid shape.
(2) It can be divided into those with surface course and those without surface course according to materials.
Grass planting brick without surface course: It is poured by mixing various clay, sand, water and straw, and is generally stored in the form of bricks. It is placed under the sun to dry and produced after the mold is removed.
Grass brick planting with surface course: add surface course on the basis of grass brick planting without surface course, and the thickness of the surface course shall not be less than 5mm. The color of grass planting brick is given by the surface course.
(3) According to the thickness of the brick, it can be divided into 70mm, 80mm, 90mm and 100mm.
The bottom layer of grass planting grid mainly consists of the following schemes:
(1) Plain soil compaction+melon seed pieces+crushed stone+melon seed pieces+grass planting grid+mixed culture soil.
(2) Plain soil compaction+crushed stone+concrete foundation+melon seed pieces+grass planting grid+mixed cultivated soil.
(3) Plain soil compaction+crushed stone+concrete foundation+melon seed pieces+non-woven blanket+grass planting grid+mixed cultivated soil.
Common parameters
Three common types of machine pressed grass planting brick specifications (mm): 250 × one hundred and ninety × 80、300 × three hundred × 80、400 × two hundred × 80。
(The above data are the product parameters of some manufacturers in the market. Different manufacturers have their own differences, which are only for reference)
Design considerations
The daily maintenance management of grass planting bricks is as follows:
(1) Paint, glue, cement and other parts attached to the surface of grass planting brick shall be shaved with a knife first, and then the coarse cotton cloth shall be dipped in pine perfume, stain removal oil or ethanol and other solvents to scrub and dry.
(2) Generally, the daily cleaning and maintenance is mainly based on dry test. First, use a broom or dust removal paper mop to clean the tiny sand, stone dust and stains adhered to the brick surface, and then use a clean towel or mop to wipe the brick surface with water.
(3) When black scratches, oil stains, rust stains and other parts caused by ironware are hard to remove from the brick surface, decontamination powder, stain removal paste, car wax, etc. can be used to scrub and clean them with clean coarse cotton cloth.

Key points of construction and installation
The key points of construction can be roughly divided into the following eight points:
(1) When paving the support layer, special attention shall be paid to ensure sufficient water permeability, but relatively The main thing is robustness.
(2) The compression condition and thickness of the support layer are determined by the assumed pressure objects (vehicles, passers-by, etc.), for example, a 30 cm thick support layer is required for load-bearing cars.
(3) Before paving grass planting bricks, a layer of 2~3cm thick sand must be paved on the support layer.
(4) Grass planting bricks can be arranged in a row or in ladder shape. All grass planting bricks shall be assembled well, and can be made into arc or other shapes with general tools.
(5) The bottom ends of grass planting bricks are staggered to make them better fixed and installed on the foundation. As required, it may be necessary to frame the whole area or fix it with fixing nails. In order to prevent possible thermal expansion of grass planting bricks, a gap of 1~1.5cm must be reserved between each grass planting brick.
(6) Grassing is done in two steps. First fill the bottom soil, then sprinkle water on the soil to make it firm, and then sprinkle grass seeds, behind Then sprinkle some soil to make the bottom soil equal to the top of the grass planting brick.
(7) During the germination period of grass seeds, always water them, and do not drive on the newly planted lawn. Once the lawn is completely grown, the area can be put into use.
(8) Often take care of the grass planting ground, hoe and fertilize frequently to maintain the grass planting environment.
