Miniature pipe jacking construction process for rain sewage pipe network reconstruction project

According to the construction technology for the miniature jacking pipe of the rain and sewage pipe network transformation project, through the steps of preparation, positioning, angle propelling, jacking, continuous propelling, section changing and dismounting, extremely high convenience and rapidity are shown in the mounting and dismounting process of the miniature jacking pipe, and the construction period is effectively shortened; in addition, the micro pipe jacking construction process is excellent in accuracy and safety of pipe jacking operation, and powerful guarantee is provided for rapid construction of urban rain and sewage diversion transformation; in a rain sewage pipe network reconstruction project, the construction technology plays a crucial role, and non-excavation type laying and repairing of the pipeline are achieved through precise mechanical equipment and a pipe jacking technology. The initial point and the end point of the pipeline are determined, the prefabricated pipeline is jacked into t
