Laying requirements: (1) Before laying, check and verify the reserved dimensions between the concrete strip and the surface layer filter material around the working face to ensure that they are on the same plane as the top of the strip after laying the hydraulic bricks; (2) When transporting river slope protection bricks, 1-2 wooden slides with a width of no more than 1.0m should be laid below the filter material from the top strip of the embankment slope. Then, the hydraulic bricks should be transported along the wooden slides to the laying surface in sequence, ensuring that the filter material layer is not damaged and reducing the loss of hydraulic bricks. It is absolutely not allowed to directly throw or throw water bricks from the top of the embankment onto the filter layer.
(3) The control of laying flatness should be carried out by hanging lines from both horizontal and vertical planes. That is, when laying river slope protection bricks, only vertical lines can be hung, and the bricks can be laid from the foot of the slope in rows upwards. At the same time, two horizontal plane lines should be hung from the top of the slope first downwards and then downwards to keep the rows in the same plane and avoid bulging.
(4) Edge joint treatment: After each working face is laid, there are inevitably varying degrees of gaps between it and the strip (especially on curved slope surfaces). If the size of the edge joint is greater than or equal to 1/2 brick, it should be repaired with hydraulic bricks first, and then filled with 1:1 cement mortar for finishing; If the size of the edge joint is less than 1/2 of the brick, simply fill the surface with 1:1 cement mortar.
