When the starting and stopping position is determined, the assembly shall be carried out according to the water flow direction indicated on both sides of the ditch body. Make sure the position and mode of drainage outlet and arrange the falling well. When the position and assembly height of the drainage ditch is accurate, it is combined with the municipal well. The direction of flow from the intake assembly to the back of the groove body. Water flow direction is shown on both sides of the ditch body. For sloped ditches, the figures on the back of the ditch indicate the direction of flow).
