[0002] There are two methods for laying underground pipelines: trench laying and trenchless laying. Trench laying refers to laying the pipeline in an open ditch after excavating it manually or using excavation machinery. It is generally suitable for ground with few surrounding buildings and underground pipelines and no paved roads. With the continuous acceleration of urban construction, the buildings are becoming more and more dense, and various infrastructures are constantly increasing, resulting in the continuous increase of underground pipelines in cities, smaller construction sites, and increasing difficulty of trench construction. Especially in the laying of underground pipelines passing through the road surface, trenchless construction is increasingly being adopted.
