AI Technical Summary
In existing technologies, the construction of drainage slopes for bridge deck drainage holes relies on manual operation, which results in problems such as low precision, long time consumption, inconsistent quality, and high cost.
The tooling for forming the drainage slope of the bridge deck drainage hole includes a forming plate and ribs. The positioning through hole matches the inner diameter of the drainage hole, the bottom surface is inclined to match the slope of the drainage slope, and the ribs are fixed in a cross shape to assist the forming process.
It improves the forming accuracy and consistency of drainage slopes, shortens construction time, reduces costs, meets standardized construction requirements, and enhances construction quality and efficiency.
