Problems solved by technology

[0002] Some underground powerhouses such as hydropower stations are located in high-altitude cold areas. During construction in winter, the invasion of the high-cold air outside the tunnel to the tunnel will cause great difficulties in construction. The environment is poor, and dust and blasting smoke cannot be removed in time, which affects the health of construction workers and the progress of the project

Abstract

The invention discloses a warm keeping, smoke dispersing and ventilating system for underground powerhouse construction in alpine regions and relates to a warm keeping, smoke dispersing and ventilating system for underground powerhouse construction in alpine regions. An air door comprises a front air door body and a rear air door body and is arranged in a tunnel, and the front air door body is arranged at the front end of the tunnel. A heat transfer device is arranged in front of the front air door body. A tunnel face is arranged in the rear of the rear air door body. A dust remover is arranged between the rear air door body and the tunnel face. The front air door body comprises an electric roller shutter I, the lower end of the electric roller shutter I is connected with a sensillum opticum I, the bottom end of the electric roller shutter I is connected with a magnetic plate I, and the magnetic plate I is matched with a magnetic stripe I for use. The magnetic stripe I is fixed on the ground. The upper end of the front portion of the electric roller shutter I is connected with a cotton curtain I, and positioning plates I are arranged at the two ends of the cotton curtain I correspondingly. The system is used for underground powerhouse construction in alpine regions.

Description

technical field [0001] The invention relates to a warm-keeping, smoke-dispersing and ventilation system for construction of an underground workshop in an alpine region. Background technique [0002] Some underground powerhouses such as hydropower stations are located in high-altitude cold areas. During construction in winter, the invasion of the high-cold air outside the tunnel into the tunnel will cause great difficulties in construction. The environment is poor, and the dust and blasting smoke cannot be removed in time, which will affect the health of construction workers and the progress of the project. Contents of the invention [0003] The purpose of the present invention is to provide a warming, smoke-dispersing and ventilation system for underground workshops in high-cold areas, which can not only ensure that workers reduce the prevalence of pneumoconiosis during construction, but also ensure ventilation and heating in tunnels in high-cold areas. [0004] Above-men...
