Roadbed step excavation method
The invention provides a roadbed step excavation method, and relates to the technical field of roadbed excavation. The roadbed step excavation method comprises the following steps: step 1, preparation work: carrying out construction lofting near a construction roadbed, and installing temporary protection walls on two sides of a roadbed road; 2, roadside cleaning is conducted, specifically, a constructor is matched with a construction machine to conduct bottom cleaning, paving, leveling and slope finishing, and a structure affecting step excavation construction is dismantled; thirdly, the slope surface is compacted; step 4, excavating layer by layer; the water content and the compaction degree of padding at the bottom of the step of the old roadbed need to be detected in time after the step is excavated, and if the water content of the padding is too large or the compaction degree is obviously insufficient, the padding is replaced. According to the roadbed excavation method, the roadbed slope surface is compacted for multiple times, the slope surface is effectively reinforced, then collapse of the slope surface is effectively prevented, follow-up step excavation work is facilitated, and the step excavation safety is greatly improved.
本发明提供一种路基台阶开挖方法，涉及路基挖掘技术领域。该路基台阶开挖方法，包括以下步骤：步骤一、准备工作：在施工路基附近进行施工放样，在路基道路的两侧安装临时防护墙；步骤二、路旁清理：施工人员配合施工机械进行清底、摊铺、平整、修坡，对影响台阶开挖施工的结构物进行拆除；步骤三、压实坡面；步骤四、逐层开挖；步骤五：挖后处理：台阶开挖后要及时检测老路基台阶底填料的含水量、压实度，如果填料含水量过大或压实度明显不足，对其进行换填处理。该路基开挖方法施工对路基坡面进行多次压实，有效对坡面进行加固，进而有效防止坡面的坍塌，便于进行后续的台阶开挖工作，大大提高了台阶开挖的安全性。
