Spacing between several earth's surface exhaust systems is 50-150 meters.
The end of the goat's horn part is located at 1-5 centimetres of water level line or less.
The pressure air quantity of the axial-flow type pressure fan is more than the summation of the exhausting amount of all propeller fans.
The sound insulation Anti-collision barrel outer wall has warning reflection patch, inner wall to be equipped with porous type sound-absorbing material.
The open area of the sound insulation Anti-collision barrel is 2 with the end area ratio of goat's horn part:1.
It is added to foaming agent in the water of shown sound insulation anticollision barreled.
The beneficial effects of the invention are as follows:
The present invention changes traditional unidirectional forced ventilation mode, and forced ventilation and exhaust ventilation are combined, and formation follows
Ring is distinguished and admirable, especially suitable for summer high temperature area vertical shaft, inclined shaft into urban shallow tunnel of constructing between the multi-region in hole, can increase and follow
The distinguished and admirable flow of ring, limited alleviation high temperataure phenomena caused by constructing in tunnel.Earth's surface exhaust system can be dusted waste air
Except dry, live on citizen and working environment is without influence, carried out Green civilization construction spirit;Easy construction simultaneously, input
It is less, it is detachable to recycle with the propulsion of face, reduce project cost.
