Construction Technology of Super-Large Diameter Steel Pipe Jacking of Municipal Water Supply and Drainage Pipe Network
The traditional construction method of municipal water supply and drainage pipe network will make the bending degree of the pipe larger and become unstable.In order to reduce the occurrence of this phenomenon,the construction method of super large diameter steel pipe jacking of municipal water supply and drainage pipe net-work is put forward,and the construction technology of ultra-large diameter steel pipe jacking is applied to mu-nicipal water supply and drainage pipe network project.Select the large-diameter steel pipe jacking equipment of the municipal water supply and drainage network,install the pipe jacking guide rail and jack,weld the steel pipe jacking groove during the installation process,and grouting the steel pipe jacking,so as to realize the large-diam-eter steel pipe jacking construction of the municipal water supply and drainage network.Carry out the experimen-tal test according to the engineering overview and the experimental preparation work,the results prove that the construction method of super-large diameter steel pipe jacking is more stable in the bending degree,which can ensure the overall quality and stability of the pipe.This technology will bring more convenience and benefits to the construction of urban water supply and drainage system.
