Outlet

There are many types of water outlets, the common one-character, eight-character and gate-character type. The location, form and outlet flow rate of the outlet of the drainage pipe should be determined according to the drainage water quality, downstream water consumption, water flow rate and water level change range, dilution and self-purification capacity, water flow direction, wave conditions, topographic changes and meteorological factors, and To obtain the consent of the local health authorities and shipping management departments, measures such as erosion prevention, energy dissipation, and reinforcement should be taken at the junction of the water outlet and the shore of the water body. Generally, cut bricks are used for retaining walls and paving. In areas affected by frost heave, the water outlet should be constructed with frost-resistant materials, and its foundation must be set below the frost line.
