目前，桩基础的前期造孔，大多采用机械施工。但在沼泽地由于没有道路，运输不畅，机械设备难以运进。即使运进去，机械造孔所要花费的工时、费用与人工造孔相比也是得不偿失的。因此，在沼泽地造孔宜采用人工施工。根据笔者多年施工经验，观介绍一种人工造孔的方法。一、人工? At present, most of the pre-hole construction of pile foundations uses mechanical construction. However, due to the lack of roads in the marshlands, transportation is not smooth and mechanical equipment is difficult to transport. Even if it is shipped in, the time and cost that it takes to mechanically create a hole are not worth the effort compared to artificial holes. Therefore, artificial construction should be used to make holes in wetlands. According to the author’s many years of construction experience, the concept of an artificial hole making method was introduced. First, artificial?
