Construction Technology of Non-excavation Directional Drilling Concrete Drag Pipe
The urban drainage network,as the infrastructure of urban construction,is the"blood vessel"of urban development and construction,playing an important role in improving the urban ecological environment,flood control and sewage discharge,and urban economic development.But with the continuous development of urbanization,the difficulty of constructing urban drainage networks is increasing.The article takes practical engineering as an example,summarizes construction experience,and proposes a non excavation directional drilling concrete drag pipe construction technology,which effectively solves the problem of urban drainage pipe network construction being unable to excavate extensively and underground comprehensive pipelines being complex and unable to be effectively protected.
