Description

Technical Field

[0001] The utility model belongs to the field of municipal engineering, and in particular relates to a tool for quickly finding the slope of a flood discharge ditch. Background Art

[0002] Flood spillways usually use trapezoidal cross-section trenches to provide the best drainage effect and stability. The slope gradient on both sides of the flood spillway is an important parameter in the slope quality and directly affects the stability of the slope. Appropriate slope gradient can effectively disperse the gravity of the soil and reduce the possibility of sliding or collapse caused by gravity. At present, the slope gradient is mostly controlled by construction layout method, which involves setting up a total station, repeatedly measuring and adjusting the position, and then laying out the slope. The process is cumbersome and the construction efficiency is low. Summary of the invention
