The invention provides a construction method of a non-earthed section containing tunnel. The method includes that an advanced medium pipe-shed support, a primary support and a secondary lining are constructed sequentially in the radial direction of a same tunnel section, the tunnel comprises a first medium pipe-shed conventional section, a first medium pipe-shed densified section, a non-earthed section located between two penumbra positions in original construction design, a second medium pipe-shed densified section and a second medium pipe-shed conventional section sequentially from back to front along the excavation direction, the axial length of each of the two medium pipe-shed densified sections is 0.5-2 times of the diameter of the tunnel, and a skylight communicating the outside with the inside of the tunnel is further arranged at the arch crown of the first medium pipe-shed densified section or the non-earthed section to facilitate subsequent transportation of construction personnel, equipment and materials. By the construction method of the non-earthed section containing tunnel, on the premise that safety in construction is ensured, rapid construction of the non-earthed section tunnel is realized, construction period is shortened, engineering cost is lowered, and influence on surroundings is reduced.
