Moreover, the problem of waste slag may also be prominent. Major measures and prevention treatment in construction are as follows:
(1) Excavation scope shall be clearly defined before construction in consideration of both construction convenience and prevention of arbitrary damage to vegetation on both sides along the route. Spoil area shall be confirmed, and the scope of spoil area shall be defined according to the conclusions in EIA report. Waste slag shall be piled in specific scope in strict accordance with technical requirements in design. We will take the open space between ramps in interflow section as spoil ground for ground clearing for convenience of planting vegetation.

Interflow (Wikipedia)
In hydrology, interflow is the lateral movement of water in the unsaturated zone, or vadose zone, that first returns to the surface or enters a stream prior to becoming groundwater.[1] Interflow is sometimes used interchangeably with throughflow;[1] however, throughflow is specifically the subcomponent of interflow that returns to the surface, as overland flow, prior to entering a stream or becoming groundwater.[2] Interflow occurs when water infiltrates (see infiltration (hydrology)) into the subsurface, hydraulic conductivity decreases with depth, and lateral flow proceeds downslope.[1] As water accumulates in the subsurface, saturation may occur, and interflow may exfiltrate as return flows, becoming overland flow.[1]
