Production and installation of head plate (5): In the mold of the head plate (5), 6mm steel bars are used as the skeleton; holes are reserved in the middle to form a connecting groove (22) to facilitate the subsequent insertion of the traction embedded parts (19); holes are reserved in the upper part to form fixing bolt holes, and flat head bolts (17) and head nuts (20) are installed to fix the head plate (5) and the arc cover plate (1); S8. Opening method of the arc-shaped cover plate (1): unscrew the upper flat head bolt (17) of the head plate (5); then, pull out the head plate (5) to expose the traction embedded part (19) with holes; use a special hook to pull the two sets of arc-shaped cover plates (1) to both sides until they reach the edge lines on both sides, then stop pulling to prevent the whole from falling off; finally, use a special hook to support the end panel (4) to complete the opening; S9, after polishing the surface layer to make it smooth and free of pollutants, perform treatment and then apply transparent waterproof coating on the surface layer of the curved cover plate (1).
