The application provides an active power-free safety
system and a mountain tunnel drainage method, and belongs to the technical field of
tunnel safety. The
system comprises a
groundwater collection module, a power
windmill module, a centrifugal drainage module and a magnetic attraction reverse prevention module. The
groundwater collection module pre-intercepts
fissure water of surrounding rock; the power
windmill module drives the
windmill by tunnel wind, and drives the driven shaft to rotate through the
bevel gear set; the centrifugal drainage module contains a porous
capillary water absorption /
water retention core body, which generates
centrifugal force with the rotation of the driven shaft to actively
discharge the collected
groundwater. The magnetic attraction reverse prevention module realizes one-way reverse prevention through magnetic force cooperation. The application does not need external power supply, relies on natural wind energy to drive, realizes proactive active drainage, and has the advantages that capillary and centrifugal synergistic effect adapts to dynamic wind conditions and
water level changes, and magnetic attraction reverse prevention effectively prevents
backflow. The application can be matched with a disposable degradable
siphon hose to assist drainage, form a composite drainage mechanism, and significantly improve the safety and reliability of tunnel drainage.
