The working hours of the permeable brick paving equipment should be well-planned according to the conditions of the construction site, and the construction water should be drawn in place with electricity and temporarily drained. In detail, the requirements are prepared from the following aspects:

1. Raw material preparation: Select the surface layer as cement and quartz sand separation materials, the permeability of the permeable brick is 1mm / s, the processing of the permeable brick is machine-pressed, and the manufacturing process is relatively simple; the paving materials are mainly conventional medium-grit, gradation Stone. Sampling and testing of the permeable bricks and sandstones entering the site are stopped, and can be used before the production quality reaches the standard.

  

2. The permeable bricks should be handled lightly, put in a stack and stacked separately according to batch, color, and category. Pervious bricks with cracks, warped corners, and surface defects should be removed. Do not mix and use different types of pervious bricks.

3. According to the construction design and plan, organize machinery and equipment and operators to enter the site for construction.

4. Construction measurement control, especially how to ensure the horizontal and vertical joints of the permeable bricks and the horizontal and vertical joints of the curbs on the two sides of the highway are different. The vertical elevation and flatness are in harmony with the highway. The measurement control is construction. Focus. One ds3-1 level and two j2 theodolites are configured for this purpose.
