Grass planting bricks have strong pressure resistance, have good stability when laid on the ground, beautify a wide area, can withstand the rolling of pedestrians and vehicles without being damaged, and the root of the green grass grows under the grass planting bricks. The grass roots will not be harmed because of this. Therefore, the foundation grass planting bricks have been widely used. Many large and small cities are also using the foundation grass planting bricks, such as Guangzhou, Changsha, Wuhan, and so on. Recognition, it can not only facilitate people to travel, but also increase the landscaping area of the city, and then improve the air. Grass planting paving is a kind of paving that cultivates grass in the holes or gaps of the bricks. If the grass is strong, this kind of paving looks like a piece of green grass, and it is flat and solid on the ground. Some are used as parking lots. The ground floor of grass planting bricks is as follows: compacted plain soil → crushed stone cushion → plain concrete cushion → fine sand layer → bricks and cultivated soil and grass seeds. Another method is: tamping of plain soil → gravel cushion → fine sand layer → bricks and cultivated soil, grass seeds.
With the further promotion of China's urbanization process, urban construction is getting higher and higher, and the buildings are becoming more and more dense. With the promotion and application of manufacturers' grass-brick system, rational design and selection of materials is very important. The sharp increase in the construction area has led to the continuous reduction of urban oasis, together with the release of various types of energy consumption and automobile exhaust, the "urban heat island effect" has become more severe, and the urban ecological environment has deteriorated. One of the effective ways to solve the above problems is to develop landscaping cultivation. Green cultivation can not only solve the problems of oasis and leisure places, but also greatly reduce the energy consumption of construction and reduce greenhouse gas emissions. Together, they can increase the accumulation of urban oasis, beautify the city, and improve the urban climate.
As can be seen from the ground floor practices of grass-brick flooring, plain soil compaction, crushed stone cushion, and concrete cushion are the same as the general ground floor practices of granite roads, except that there is a fine sand layer in the grass-brick flooring. And the difference between the two surface materials. Therefore, the key to the grass-planting brick laying method is also the paving of the surface-planting grass-brick.
Grass planting bricks commonly used now include two-hole bricks made of cement, and small cement bricks without holes. When laying grass-planting bricks, the distance between the bricks and the bricks is generally about 50mm. The center is here, the cultivation soil is sprinkled, and then the grass seeds are dialed. Now there is also a cultivated grass brick joist. This is a jog made of plastic with a certain strength. The product is 500mm × 500mm. It is laid directly on the ground and sprinkled with cultivation soil. After the grass is cultivated, it becomes Planted grass paving.
The above is the sharing of Guangzhou square pavement manufacturers.
