When laying straw bricks, we should pay special attention to the following problems.
When laying the supporting layer, we should ensure sufficient water permeability, and at the same time, we should not ignore the firmness; The compression condition and thickness of the support layer are determined by the pressurizer; Before laying, lay a layer of 2-3cm sand on the supporting layer.
Grass planting bricks can be made into arcs or other shapes with common tools. Before laying, the grass planting bricks should be spliced in good condition and can be spliced into a row in a trapezoidal arrangement.
When paving grass bricks, grass bricks can be well fixed on the foundation by staggered arrangement, and the peripheral area of the whole block needs to be framed or fixed with fixing nails when fixing. In order to avoid thermal expansion, 1- 1.5cm should be reserved before each brick.
When planting grass, first fill in the soil at the grass-roots level, then sprinkle water to stabilize it, then sprinkle grass seeds, and finally sprinkle soil to make it equal to the top of the grass-planting brick.
Do not use this area during the germination of grass seeds. After put into use, you should always take care of the grass-planted pavement.
