What is a trail brick? What should I pay attention to when laying paving paving bricks?
First of all, what is a trail brick?
1. Trail brick is an artificial board made of concrete, fly ash, etc. At the same time, its shape is larger than that of brick, so it can be constructed quickly. Trail bricks are also divided into small, medium and large bricks, and medium and small bricks are generally used.
2. Trail bricks are divided into porous grass-planting bricks in appearance, and the forms are divided into single row of square holes and multiple rows of flat hole lights. Porous bricks can be better used in plants, followed by main bricks and auxiliary bricks according to their functions. In addition, the footpath bricks with high water absorption can not be soaked in water often, which will shorten their service life.
Second, what should be paid attention to when paving bricks are laid?
1. First, clean the sundries on the surface of the base, rinse them with clean water at the same time, and then lay them according to the design drawings. When paving, determine the position first, then wet the brick with water first, and then use it when there is no water on the surface of the brick.
2. Sprinkle water on the construction ground surface, and then brush the cement mortar evenly. When brushing, the area should not be too large, but as much as possible. Secondly, the coating thickness should be controlled at 10 mm to 25 mm, and the paving height should be 3 mm to 4 mm higher than the surface layer. After paving, scrape it with a ruler, and then scrape it with a tool.
3. When mixing, hard mortar should be used, which can be held in hand to form a ball, preferably scattered on the ground. In addition, after two or three rows of paving, it is necessary to check the verticality of the joints, and the irregular places should be repaired in time and hammered with a hammer.
4. After paving is completed, the seam sweeping process should be carried out, which can be carried out with cement sand of 1: 1. Secondly, after laying for 24 hours, it should be watered for at least one week. People can only get here when the strength of the newly laid pavement brick is very hard. At the same time, cement mortar should not be placed on the paved sidewalk brick, so as not to stick to it and affect the appearance.
Editor's summary: I'm here to introduce what is a trail brick and the matters needing attention when laying it. In addition, when using the pavement brick, you can't scrape its surface with sharp tools, which will not only reduce the aesthetics, but also shorten its service life.
