Subterranean junction shield tunneling method and that shielded machine of tandem tunnel

摘要

Abstract Topic The earth the small diameter seal of the acceptance side shielded machine junctionWhile supporting tare weight, maintaining seal Characteristic, it goes back the do machine,Concrete means because of the ru are shown the acceptance side shielded machine whereIt is. Solutions Acceptance side shielded machine R large diameter shielded machine NWith two step type shielded machines which are formed with from small diameter shielded machine MTo form, this large diameter shielded machine itself 8 and the small diameter shielded machine manualAs the support component is provided with bodies 1, both shielded machineTo provide the seal component which maintains the seal Characteristic between computer 1,8, thisSeal component, seal Characteristic and small diameter shielded machine M when diggingThe seal component 14,15 which maintains the seal Characteristic of the last retreating/quitting time and, smallInside large diameter shielded machine N where diameter shielded machine M went back penetrationFacing toward the computer outside cylindrical surface of the se ru penetration side shielded machine the large diameter sealThe tube seal 13 which swells from do machine N and 3 where it consists of it is heavyIt consists the seal.
