Thus, during the process of foundation pit excavation, the construction operation will affect the stability of the highway slope and the safety of driving. The traditional method is to use concrete piles with a diameter of 1.5m~1.8m for temporary protection of the slope, but the pile foundation construction needs to use large pile foundation equipment, and at least half of the road needs to be occupied during construction, which makes the land occupation area large and the construction period long.
