Problems solved by technology

[0004] Although the double-hole complementary ventilation has the advantages of economy, it has certain limitations in application, that is, it is suitable for the situation where the air volume of the uplink and downlink tunnels differs greatly, and for the case where the ventilation load of the uplink and downlink tunnels has little difference, it can realize Unsatisfactory effect

Embodiment

[0063] Aiming at the current situation of ventilation methods for most extra-long mountain tunnels in China, from the perspective of saving energy and reducing civil construction costs, and according to the calculation principles in the detailed rules for ventilation design of highway tunnels, the present invention proposes a single-channel and vertical (inclined) shaft in long tunnels. Modular ventilation design, using different module combinations for ventilation, giving full play to the advantages of different modules under different geological conditions, achieving energy saving in tunnel ventilation design, saving civil engineering costs, and improving the convenience of smoke exhaust organization in case of fire.

[0064] The system can be used in mountainous super-long highway tunnels. The single channel part and the vertical (inclined) shaft part are modularized and combined. The vertical (inclined) shaft can effectively discharge the polluted gas in the tunnel, send in ...

Abstract

The invention relates to a single-channel and vertical inclined well modular ventilation system in a long and large tunnel. The single-channel and vertical inclined well modular ventilation system isformed by splicing and combining one or more of a first ventilation module, a second ventilation module, a third ventilation module and a fourth ventilation module, and is used for satisfying requirements for ventilation of the long and large tunnel through real-time monitoring of ventilation parameters in the tunnel, dynamic intelligent calculation and fan operating state adjustment. Compared tothe prior art, the single-channel and vertical inclined well modular ventilation system has the advantages of modular design, low energy consumption, dynamic intelligent control, energy-saving tunneloperation, rapid transformation of normal and fire working conditions, and the like.

Description

technical field [0001] The invention relates to the field of tunnel ventilation, in particular to a single-channel and vertical shaft modular ventilation system in a long tunnel. Background technique [0002] With the rapid development of highway construction, a large number of extra-long highway tunnels, especially tunnels with a length of more than 4km, have appeared. The question of whether to add shaft ventilation during tunnel construction has attracted widespread attention. The concentration of harmful gases in extra-long highway tunnels is high, and it is relatively difficult to discharge or dilute them. The primary problem in construction and operation is tunnel ventilation. Tunnel ventilation research mainly focuses on the selection of mechanical ventilation methods, the setting of ventilation shafts, the evaluation of mechanical ventilation effects, and the ventilation mode under fire, etc. Throughout the evolution of highway tunnel ventilation methods in various ...
