石牙山特长隧道送排风混合式通风方案设计

Design of Send-eject-wind Composite Ventilation Scheme of Extra-long Tunnel in Shiya Mountain

本设计方案从工程施工通风和现有设备出发,本着"安全、可靠、经济、合理"的原则进行施工通风方案的设计,通过方案技术与经济比较,选择适合隧道施工期间的通风设计方案——送排风混合式通风,解决隧道施工期间通风问题,创造舒适施工环境。

Based on engineering ventilation and existing equipment, this scheme is designed according to the principle of ＂safety,credible,economic and reasonable＂.By comparing technology with economy,the author chooses a suit- able scheme---Send-eject-wind composite ventilation scheme.This scheme can solve the ventilation problem during construction and create comfortable environment.
