一般挖方地段为内侧设50×80厘米的直墙，边沟底宽50厘米，深50厘米，外侧坡度为1：1，沟底厚30厘米。边沟纵坡一般与路基纵坡一致。对于汇水面积较大的边沟或农田灌溉渠合一的边沟，采用加宽加深改沟形式，以保证设计泄洪能力，

結果 (英文) 1:

General excavation area 50x80 cm for the inner vertical walls, ditches bottom width 50 cm, depth 50 cm, the outer slope of 1:1, the bottom 30 cm thick. Ditches longitudinal slope and roadbed slope line. For larger catchment area of ditches or farm irrigation ditches, with wide and deep ditch modified forms, to ensure the design flood discharge capacity

結果 (英文) 2:

Usually located inside of the excavation area is 50 × 80 cm straight wall, ditch bottom width of 50 cm, 50 cm deep, outer slope of 1: 1, the ditch 30 cm thick. Ditch Embankment Longitudinal Longitudinal generally consistent. For larger catchment area drainage ditches or irrigation ditches unity, deepen reform adopted widened ditch forms in order to ensure that the design flood discharge capacity,

結果 (英文) 3:

Straight wall excavation sections located inside for 50 x 80 cm, side ditch bottom 50 cm wide, 50 cm deep, outside slope 1:1, gully bottom 30 cm thick. The longitudinal slope of the side ditch is generally consistent with the longitudinal slope of the roadbed. For a larger catchment area ditch or irrigation canal and ditch a ditch, the wide and deep change form, to ensure the design flood discharge capacity,
