| Zusammenfassung: | A construction adit structure penetrating through multiple diversion tunnels comprises a construction adit used for constructing the multiple parallel diversion tunnels, the construction adit penetrates through the upper flat sections of the multiple diversion tunnels and is perpendicular to the upper flat sections of the multiple diversion tunnels, the construction adit is excavated in two layers, the section of the first layer of construction adit is in a city gate opening shape, and the section of the second layer of construction adit is in a city gate opening shape. After a first layer of excavation and support of the upper flat sections of the diversion tunnels are completed, bottom reduction of a second layer of construction adit is conducted on the intersection section of the construction adit and the upper flat sections of the diversion tunnels till the position above a bottom plate of the diversion tunnels, and after a second layer of excavation and support of the upper flat sections of the diversion |
