Application of Large-diameter Dragging Pipe Construction Technology in Connecting Ditches and Crossing Highways
The large diameter horizontal directional drilling construction technology,as a new construction technology,has a relatively short construction period,minimal interference to the surrounding environment,and high construction safety.It is widely used in the construction of underground urban pipeline networks.In order to protect the existing infrastructure,the dragging pipe construction method has been adopted,and large-scale excavation operations are not required during the horizontal directional drilling dragging pipe construction.The key is to use a guiding device to control the guiding drill bit to drill along the axis of the designed pipeline during construction.This construction technology is a green and environmentally friendly building construction technology,which has been applied in the construction of connecting large diameter HDPE pipes under urban roads.
