Beschreibung
Zusammenfassung:	The invention relates to a mountainous area pipeline entry and excavation technical method. The method comprises the following steps: basic entry requirements; exploring and planning; entering technical requirements; excavating an operation pit; the approach technical requirement comprises terrain judgment; if the gradient is smaller than 35 degrees, the entering mode is preferentially selected according to the sequence of excavator transportation, Z-shaped road construction transportation, mountainous region comprehensive pipe transportation vehicle transportation and mountainous region pipe distribution machine transportation, and if the gradient is between 35 degrees and 45 degrees, the entering mode is preferentially selected according to the sequence of mountainous region comprehensive pipe transportation vehicle transportation and mountainous region pipe distribution machine transportation; if the gradient is larger than 45 degrees, the entering mode is preferentially selected according to the sequence
