Before the installation of FRP gratings, the specifications of different FRP gratings are different, and the load capacity or willfulness are also different. Then, the appropriate FRP gratings are purchased according to actual needs and started to be laid and installed.
1. Before laying (installation), make the drainage channel, and the drainage pipeline should be pre-buried. The width of the outer opening of the drainage channel should be less than 5% of the width of the fiberglass grating, and the width of the inner opening should be less than 10% of the width of the fiberglass grating. The lower the width of the inner opening, the greater the carrying capacity of the grille, but the smaller the drainage capacity will decrease, so the ratio must be controlled.
2. After the drainage channel is completed, start to formally lay the glass fiber reinforced plastic grille. The grille is laid flat according to the requirements. The inner opening of the drainage channel is around the grille, and the distance from the outer opening of the drainage channel is equal, so that the force will be uniform in the later stage.
3. Fix the glass fiber reinforced plastic grille, fill the gaps with 705 glass glue around the sides, and cover the gaps with 302 cement after the glue is dry.
4. Post-processing, after laying, check whether the laying is in place, and carry out stress test to ensure the project wm****.
