Abstract

The invention provides a high-ground-temperature tunnel ventilation cooling device and an advanced cooling method, and belongs to the technical field of tunnel construction. The high-ground-temperature tunnel ventilation cooling device comprises a ventilation assembly and a first refrigeration assembly. When the high-ground-temperature tunnel ventilation cooling device is used, a fan introduces relatively low-temperature air outside a tunnel into a first ventilation pipe and discharges the relatively low-temperature air into the tunnel, so that the ventilation quantity in the tunnel is increased, the stuffiness feeling of constructors is reduced, and the working environment is improved. A plurality of first refrigeration bags are arranged on the surface of a connecting sleeve, and the connecting sleeve is arranged on the outer wall of the first ventilation pipe in a sleeving mode. The refrigeration bags become solid in a low-temperature environment, the refrigeration bags are arrangedon the outer wall of the first ventilation pipe in a sleeving mode, the air entering the first ventilation pipe can be cooled, the situation that the air enters the tunnel to be spread to form hot aircan be avoided to a certain extent, and the cooling effect is improved.

Description

Technical field

[0001] The invention relates to the technical field of tunnel construction, in particular to a high ground temperature tunnel ventilation and cooling device and an advanced cooling method. Background technique

[0002] A large number of high-altitude, long-distance tunnels and complex geological conditions have appeared in China. Among them, the deterioration of the construction environment caused by high ground temperature, the higher the temperature of the working surface, the serious loss of water and salt in the body of the construction personnel in the high temperature and high temperature work environment, if not timely supplemented, the construction personnel are prone to heat collapse and reduce work efficiency. In addition, the high ground temperature environment causes insufficient pullout resistance of the anchor rod, and even causes the anchor rod to fail and cannot be anchored. The high ground temperature environment will also reduce the safety of th...
