Problems solved by technology

[0002] In the current tunnel construction, the site is full of dust, and the upper exhaust method causes turbid and polluted air to permeate around the human body's breathing and ventilation. Tunnel construction personnel have been working in turbid air for a long time, causing silicosis and physical discomfort.

Embodiment Construction

[0024] Shaft construction principle:

[0025] The shaft can be built vertically on the mountainside or on the top of the mountain or near the tunnel entrance after lying on the mountain for a certain distance. The main construction of the shaft follows the general civil engineering method. The long tunnel requires a large amount of ventilation. , Install a general-purpose wind turbine on the top of the shaft, flange connection, open at the bottom of the shaft, install a jet tee device, and connect the exhaust pipe.

[0026] Exhaust principle:

[0027] In the tunnel, a wind turbine is installed to uniformly deliver the fresh air to the exhaust duct and the fresh air duct separated by the partition board. The fresh air sent into the exhaust duct provides wind energy for the exhaust duct, forming a combination of wind energy drive in the lower part and shaft effect in the upper part. The combined exhaust method effectively improves the exhaust effect and reduces the equipmen...

Abstract

The invention relates to a ventilation system and a ventilation method for tunnel construction. The system consists of a wind turbine, an air exhaust vertical shaft, a jet flow tee joint, an exhaust duct, a filter connection tee joint, a fresh air duct, a tee joint purification foundation, a separation air duct, a fan, and a fresh air filter; a ventilation vertical shaft is constructed outside a tunnel before construction, and during construction, air feeding is adopted on an upper part, and exhausted air on a lower part is directly filtered and removed; a fresh air machine can drive fresh air and exhausted air synchronously, wind energy is fully utilized, and energy is saved and emission is reduced; and the system can be industrially designed, and produced in the standardized, generalized and serialized mode, can be widely applied to tunnel construction industry, mining industry, dust operation industry and other industry, and belongs to the field of tunnel construction and ventilation and purification.

Description

technical field [0001] The invention relates to a tunnel construction ventilation system and a ventilation method. The system consists of a wind turbine, an exhaust shaft, a jet tee, an exhaust duct, a filter connection tee, a new air duct, a tee purification base, a partition air duct, a fan, The fresh air filter is composed of; before construction, a ventilation shaft is built outside the tunnel. During the construction, the upper part is used to supply air, and the lower part is used to directly filter and remove the exhaust air; a fresh air fan drives the fresh air and exhaust air synchronously, making full use of wind energy, saving energy and reducing emissions, and can be industrialized. Design, Standardized, generalized, and serialized production can be widely used in tunnel construction, mining, and dust operations in various industries, and belongs to the field of tunnel construction and ventilation and purification. Background technique [0002] In the current tun...
