在路堑开挖和路堤填筑施工中，工程车辆配合挖掘机所需的车辆数量不仅与挖掘机和工程车辆的性能有关，还与运输距离、道路条件、驾驶员操作技术等因素有关。一般可以通过估算的方法得到，然后通过具体的操作来实现。在这个过程中，原则是保证挖掘机不中断作业，不让工程车等待。挖掘机在进行平面挖掘时，可以采用垂直挖掘法和等分挖掘法。垂直开挖法，挖掘机在工作面垂直开挖。垂直开挖法的优点是挖掘机的两侧都可以停放工程车辆， 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.
