Background With the increasing importance of countries on water environment, the construction amount of various pipe network projects is continuously increased, and for pipe network projects in urban central areas, the original electric power, telecommunication, tap water, drainage and other pipelines are distributed on the pipe network lines in an intricate and complex manner, so that the construction process of new pipe network projects often involves the protection of a large number of existing pipelines. And for the construction engineering of the newly-built pipelines with denser distribution, the construction is mainly carried out by adopting an open cut method, and for the protection of the existing pipelines in the groove range of the newly-built pipelines constructed by adopting the open cut method, a suspension method is mainly adopted, wherein one end of a steel wire rope is suspended on a ground channel steel, and the other end of the steel wire rope is suspended on the existing pipelines. The method is most widely applied at home and abroad, but after being well suspended, the method generally has a loose condition, does not have a tensioning and adjusting function, cannot guarantee potential safety hazards, and easily has a condition that an existing pipeline sags due to the fact that a steel wire rope is loose in a construction process, so that the existing pipeline is deformed excessively or damaged. Once accidents are caused, the problems of slow engineering progress, large influence on surrounding environment and large construction risk are caused, and after the traditional suspension protection method is adopted, the construction space of a newly-built pipeline is restricted, and the construction efficiency of the newly-built pipeline engineering is reduced. Therefore, it is necessary to provide a pipeline protection system for controlling deformation of an existing pipeline and a pipeline protection method for controlling deformation of an existing pipeline, so as to control deformation of an existing pipeline within a normal range, and simultaneously realize pipeline protection of an existing pipeline, and improve construction efficiency.
