Relay press-in type and roadway type combined ventilation system

Abstract

The invention discloses a relay press-in type and roadway type combined ventilation system. The relay press-in type and roadway type combined ventilation system comprises a left tunnel, a right tunnel, an air supply inclined shaft, an air exhaust inclined shaft, an air duct isolation device, a variable-frequency axial flow fan, a first anti-explosion variable-frequency axial flow fan, a second anti-explosion variable-frequency axial flow fan, a first air pipe, a second air pipe and a third air pipe. The relay press-in type and roadway type combined ventilation system has the advantages of good ventilation effect and low ventilation cost.

Description

technical field [0001] The invention relates to a ventilation system, in particular to a combined ventilation system of relay press-in type and roadway type. Background technique [0002] Due to the complex construction environment characteristics of super long-span gas tunnels such as large tunnel section, long air supply distance, long construction period, many construction machinery and equipment personnel, and containing gas when passing through coal-measure and non-coal-measure gas strata, the construction ventilation air volume, Ventilation technology and ventilation management have put forward higher requirements. Existing ventilation schemes such as press-in type, tunnel type, and jet tunnel type have high construction costs, and the construction requirements of the wind wall 6 are high, the ventilation effect is poor, and the energy consumption is high. The highway tunnel construction ventilation control technology combined with inclined shaft and cross passage 5 i...
