Problems solved by technology

[0002] The pavement methods of the existing pavement bricks generally adopt the following two methods after the composite soil is rolled: one is the full sand cushion, and the pavement bricks are laid on the sand. Although the full sand cushion has good water permeability, the disadvantage is that it is not durable , no load
When it rains in a hurry, the sand layer at the bottom of the pavement bricks is washed away by the rain, resulting in uneven pavement of pavement bricks. This kind of pavement brick paved with full sand is easy to sink when the vehicle is pressed down, making the road surface uneven.
The other is the concrete cush

specific Embodiment approach 1

[0005] Specific implementation mode one: (see figure 1 ) This embodiment is achieved through the following steps: one, the original soil layer of the road bed is rammed or compacted with a rammer or a road roller; On the top, the paving thickness of the crushed stone is 30-200mm; 3. Laying the graded layer: lay the gravel and stone powder on the crushed stone layer, push it flat and then spray water for compaction, and the laying thickness of the graded layer is 10-200 mm. 100mm; 4. Laying the backing layer: After mixing the crushed stone and fine sand, spread it on the gradation layer, and sink it with water. The thickness of the backing layer is 10-50mm; The machine will tamp the backing layer, and then lay the pavement bricks, the thickness of the pavement bricks is 50-80mm. The average diameter of the gravel used in the crushed stone layer is 1-3cm or 2-4cm; the average diameter of the gravel in the graded layer is 0.1-2mm, and the particle size of the stone powder is 0.0...

Abstract

A method for laying the bricks of water-permeable pedestrian include such steps as tamping the bed of pedestrian, spreading broken stone layer, spreading the mixture of ballast and stone powder, levelling, spraying water, compacting, spreading liner layer of broken stone and fine sand, spraying water and laying bricks. Its advantages are high air and water permeability, smooth pavement, high load-bearing power, and low cost.

Description

Technical field: [0001] The invention relates to the field of municipal environmental protection engineering, in particular to a method for paving pavement bricks. Background technique: [0002] The pavement methods of the existing pavement bricks generally adopt the following two methods after the composite soil is rolled: one is the full sand cushion, and the pavement bricks are laid on the sand. Although the full sand cushion has good water permeability, the disadvantage is that it is not durable , No load bearing. When the rain falls rapidly, the sand layer at the bottom of the pavement bricks is washed away by the rain, resulting in uneven pavement of pavement bricks. This kind of pavement brick paved with full sand is easy to sink when the vehicle is pressed down, making the road surface uneven. The other is the concrete cushion. Although this cushion is resistant to heavy pressure and has good stability, its disadvantages are that it is airtight and watertight, and t...
