Abstract

He shan tunnel as the expressway one. Which is the key project of expressway coiling the city. The design of cave passage adopts whittles the bamboostyle hole door, style in order to look pretty good. As to lining cutting, composite style is my choice lightly excavate is my way for the beginning of cave passage as well as entire lining cutting. Entilation in the tunnel is adopted in the efflux style machine direction way. In addition, 10 seriess of 20 air-blowers which dimeter are 1120mm. Natrium lighting is for lighting. When building it, it will be exploded all-around way and somooth surface will be left after exploding. In the course of practising the scitntific management will be a necessary step. Key words : Composite style lining cutting 、Ventilation、Lighting、Exploding in all-around way.
