How to lay ground paving stones

Determine the vertical connection method for the edge zone of the ground paving stone based on factors such as buildings, garden roads, and pipelines near the site, and adjust the ground elevation of the connection points. It is also necessary to confirm the location of the ground drainage outlet and adjust the elevation of the bottom of the drainage ditch pipe to make the connection between the square ground and the surrounding ground more natural, reducing conflicts in drainage, channels, and other aspects. How can we better lay the ground paving stones?

paving stone

1. Material preparation
In the paving stone project of the garden road, the preparation work of paving materials is relatively large. Therefore, when determining the plan, the layout on the drawing should be based on the actual size of the paving square, and the adjustment of the corner plan and the transition plan at the junction of the square and the garden road should be determined. Then, the quantity of various paving stones and the specifications and quantities of corner materials should be determined. Because in actual construction, the above problems are often encountered.
2. Site layout
According to the construction coordinate grid of the ground paving stone as shown in the design drawing, all coordinate points are measured and set on the site, and pile driving is carried out. Then, based on the coordinate pile points, according to the square design plan, the boundary lines of the site, the range lines of the main ground facilities, and the zero lines between the excavation and filling areas are marked on the ground.
3. Terrain review
Refer to the vertical design plan of Yuanlu Square and review the terrain of the site. The natural floor elevation data of each coordinate point and control point, and any missing ground paving stones should be measured and supplemented on site.
The filling sequence of the stone filled area on the ground should be deep first and then shallow, with the deep areas filled layer by layer first and the shallow areas filled later. Each layer should be compacted one layer at a time. Until the designed elevation. The fertile soil suitable for planting excavated during the excavation process should be temporarily piled up by the square and later filled into flower beds and planting areas.
