Abstract

The invention discloses a long-distance tunnel relay ventilation method, and relates to the technical field of tunnel construction, mainly aiming at solving the problem that the tunnel construction ispoor in ventilation effect. The method comprises the following steps: S1, adopting an ordinary tunnel press-in ventilation way before a tunnel is tunneled to 1200 meters; S2, adopting a roadway ventilation way after the tunnel is tunneled to 1200 meters; S3, when the tunnel is excavated to 2500 meters, adopting tunnel face ventilation through a left line hole and a right line hole, and moving a fan arranged outside the left line hole inwards to the front of a third fan section for ventilation; S4, continuing to tunnel forward along with a tunnel face. The fan arranged outside the left line hole, a fan arranged outside the right line hole, a first fan, a second fan and fan sections are cooperatively used, so that the ventilation effect of the tunnel construction is fully guaranteed, the work environment of construction in the tunnel is improved, and the phenomenon that the health of workers is affected by excessive dust, impurities and the like is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a relay ventilation method for long-distance tunnels. Background technique [0002] With the rapid development of my country's railway industry and highway industry, my country's tunnel industry is facing new challenges. The number and construction scale of tunnel projects continue to expand, and the level of mechanized construction is getting higher and higher. In the process of tunnel construction, good ventilation is an important source that affects the physical and mental health of front-line construction workers, and it is also a bottleneck for the progress and quality of the project. How to ensure the ventilation effect of tunnel construction and improve the construction working environment in the tunnel is one of the key issues that my country's tunnel industry is concerned about. [0003] In tunnel construction, various kinds of dust are often mixed in the ai...
