Do not mechanically excavate too deep but first by 300mm and then 100mm each to avoid destructing pipelines. If there are pipelines, immediately take manual C581 南線開挖到臨時道路，通過其它承包商倉庫的時候先不開挖斷，等電纜溝開挖到最后的時候再回頭開挖這部分，開挖后并在這些地段鋪上木方。Excavate side earth should ensure the stability of the slope and upright. When the soil is fine, throw earth on the groove side (or material) away from the pit (groove) edge with height more than 1m. Stack backfill soil if it has conditions and move the excess earth out to avoid secondary 6） 土方開挖部分采用人工開挖為主，部分區(qū)域在保證人員，設(shè)備安全，不損壞現(xiàn)有管線的基礎(chǔ)上采用機(jī)械開挖，槽底預(yù)留 20cm 由人工清底。Generally clay can be excavated from top to bottom by layer with the appropriate depth 60cm. backward excavate from the end by stepping 碎石類土先用鎬翻松，正向挖掘，每層深度，視翻土厚度而定，每層應(yīng)清底和出土，然后逐步挖掘。根據(jù)建設(shè)方提供的現(xiàn)況地下管線圖，進(jìn)行現(xiàn)場調(diào)查探摸，在每個開挖路線上，每隔 30m 進(jìn)行人工開挖試空井，明確整個斷面有無其它管線，及其管線分布情況，采取有效措施加以保護(hù)。Alignment measurement needs to determine the centerline and corners, and measure grooves and adjacent permanent building location relations.
