Automatic ventilation system for tunnel construction

Abstract

The invention discloses an automatic ventilation system for tunnel construction. The automatic ventilation system comprises a plurality of air condition detection units, an upper monitor, an electric ventilator arranged at a constructed tunnel opening and ventilation pipeline construction vehicles. Each ventilation pipeline construction vehicle comprises a traveling trolley, a traveling driving mechanism, a pipeline retracting and laying device, an electric pipeline retraction and laying driving mechanism and an electronic circuit board. A flexible air pipe is continuously wound on a winding shaft of each pipeline retracting and laying device from inside to outside. A controller, a traveling direction detection unit, a traveling position detection unit, an air supply volume detection unit and a first wireless communication module are arranged on each electronic circuit board. The rear end part of each flexible air pipe is connected with an air supply outlet of the electric ventilator, and the front end part of each flexible air pipe is fixedly arranged on the corresponding traveling trolley. The automatic ventilation system is simple in structure, rational in design, convenient to operate and high in intellectualization degree, and has good using effects, and the problems of heavy field workload, more manpower and material resource investment, inconvenience for operation, relatively poor ventilation effects and the like of the conventional ventilation system for tunnel construction can be solved.

Description

technical field [0001] The invention belongs to the technical field of tunnel ventilation construction, and in particular relates to an automatic ventilation system for tunnel construction. Background technique [0002] As we all know, ventilation in tunnel construction is a key process. Its function is to deliver enough fresh air from outside the tunnel to the inside of the tunnel, and to discharge the gun smoke and harmful gases generated by blasting and transportation in the tunnel, so as to finally ensure the safety of the workers and machinery in the tunnel. The need for fresh air makes the air in the cave meet the standards stipulated by the state and industry. The quality of the ventilation effect in the construction of long tunnels directly affects the progress of the project and the health of the workers. At present, the tunnel construction ventilation at home and abroad mostly adopts the pipeline press-in ventilation method, and an axial flow fan is installed outs...
