在路塹開挖和路堤填筑施工中，工程車輛配合挖掘機所需的車輛數量不僅與挖掘機和工程車輛的性能有關，還與運輸距離、道路條件、駕駛員操作技術等因素有關。一般可以通過估算的方法得到，然后通過具體的操作來實現。在這個過程中，原則是保證挖掘機不中斷作業，不讓工程車等待。挖掘機在進行平面挖掘時，可以采用垂直挖掘法和等分挖掘法。垂直開挖法，挖掘機在工作面垂直開挖。垂直開挖法的優點是挖掘機的兩側都可以停放工程車輛， and the engineering vehicles on one side can be loaded when transported, and the turning angle of the excavator does not exceed 80, which is beneficial to improve the working efficiency.

The causes of cracks in the side plate of excavator boom include bubbles, slag inclusion and micro cracks in the original weld. When the excavator is overloaded, micro cracks will occur in the original weld and expand slowly. When welding, the covered electrode does not match the performance of the plate, resulting in cracks. Because of the large size of the excavator boom, it is difficult to adopt reliable and effective heating and insulation measures, and the hardened zone of the base metal around the weld cannot be removed after welding, resulting in the decrease of weld strength. During the operation of the excavator, the vibration impact is large, and the uneven stress at the weld cracks.
