The slope protection forms of river slope protection bricks include direct slope protection and indirect slope protection. Direct protection refers to directly reinforcing the bank slope to resist the erosion and washing of water flow. Commonly used types include throwing stones, dry rubble stones, mortar rubble stones, gabions, and pointed bundles. Protection is indirectly applicable to river sections with wide riverbeds or long protection lengths, and can be constructed with spur dikes, parallel dams, lattice dams, etc. to bring water away from the riverbank. Some plants can be artificially planted in the pores of this revetment to enhance its aesthetic appeal.
Hollow during grass planting brick construction can be prevented. Before construction, the ground should be flat. Not only should the ground be flat, but there should also be no stones on top to avoid unevenness caused by stones during construction. Even if the construction of river slope protection bricks is initially flat, there may still be unevenness in the later stage.
In addition to the factors of the ground itself, there is also the quality of the cement concrete used. During construction, it should be kept moist appropriately, not too dry, and of course not too wet. Too much moisture can affect drying time and effectiveness, while too little moisture can cause poor adhesion. In order to ensure the construction quality of the river slope protection bricks, there will be no hollowing. Applying cement mortar on the back is an effective method to prevent hollowing. You can try to see the effect.
River slope protection bricks have strong flood control capabilities. The self embedded retaining wall structure is stacked layer by layer, without the need for mortar masonry, and water flow can quickly enter and exit, reducing the damage of waves to the wall and having a sense of hierarchy. When the plants between the stomata grow up, they can cover the walls. Compared with concrete walls, river slope protection bricks have ecological awareness. The underwater pores provide a good habitat for animals such as fish and shrimp, with simple construction, no noise, and easy dismantling in the later stage.
