Description
Technical Field
The invention relates to the technical field of tunnel exhaust, in particular to an exhaust system of a city tunnel without a wind tower.
Background
With the increasing awareness of ecological environment indexes such as high-quality air quality, the emission of polluted air in the tunnel becomes one of the most sensitive problems in tunnel construction.
The polluted air discharge scheme in the tunnel mainly adopts concentrated discharge. The centralized discharge is divided into high-altitude centralized discharge and hole centralized discharge. The high-altitude centralized discharge is to discharge polluted air through a high wind tower, which is beneficial to the diffusion and dilution of pollutants and has the minimum influence on the surrounding environment; the concentrated discharge at the hole outlet is not beneficial to the dilution and the diffusion of pollutants, and has great influence on the surrounding environment.
No matter high altitude discharges or portal discharges, great challenge is provided to the construction of urban tunnels: high wind towers are required to be arranged for high-altitude emission, the first problem is land acquisition, and the second problem is the influence of peripheral landscapes and environment on the arrangement of the high wind towers; due to the limit of dense urban sensitive buildings, the discharge of polluted air at the exit cannot be realized.
The person skilled in the art is dedicated to solving the above technical drawbacks.
