What are the key issues to be aware of when constructing U-shaped groove molding machines? Here are several points:

The U-shaped groove forming mechanism is pre-cleaned at the cement joint before缝ing, coated with a layer of cement slurry, and sealed with 1:2.5 expanded cement mortar.

2. The embankment along the channel requires that the particles from the U-shaped channel molding machine be no larger than 20 cm, with uniform density and a smooth finish.

3. According to the design specifications, a gantry pile is set every 30 meters, with the channel's shape as the standard, matching the U-shaped slab construction, and meticulously finishing the channel.

During the lining process, the bottom of the board is paved with 75# cement mortar at a thickness of 3-4 cm, with a width of no less than 15 cm, and joints in both directions are 2.0-2.5 cm wide.
