Main advantages of non-excavation underground pipeline construction technology

(1) Resolving the interference of traditional excavation construction on the normal life of residents, reducing the damage and adverse effects on the transportation, environment and surrounding building foundation;
(2) Where the traditional construction method cannot be constructed or excavation is not allowed, the non-excavation technology can be used to traverse the pavement from below, and the pipeline design can be passed through at the best position with the least amount of engineering;
(3) It is possible to control the laying direction and depth of underground pipelines with high precision, and to make pipelines bypass undiscovered underground obstacles (such as boulder and underground structures);
(4) Under the same comparability, the comprehensive cost of laying, replacing and repairing non-excavation pipelines is lower than that of excavation method. And because of the increasing depth of urban pipelines. The cost of excavation construction increases sharply with the increase of buried depth and pipe diameter, and the superiority of non-excavation construction is more remarkable.
