Technical Field

[0001] The utility model belongs to the technical field of tunnel engineering, and more specifically relates to a tunnel ventilation inclined shaft system and a tunnel system which are also used for escape. Background Art

[0002] Inclined shafts are spatial structures arranged along the tunnel slope, which have the functions of ventilation and smoke exhaust. Specifically, in tunnels, exhaust gas emitted by motor vehicles can cause problems such as air pollution and hypoxia, and may even cause accidents.

[0003] However, in the existing inclined shaft design, no special escape passage is set up. For example, the passage for vehicles and personnel is the same passage. The layout of the inclined shaft makes it easy for accidents to occur when personnel and vehicles are in the same passage when a fire occurs, and it does not have the function of dispersed escape.

[0041] Embodiment 2

[0042] Embodiment 2 of the present utility model provides a tunnel system, which includes any one of the above-mentioned tunnel ventilation inclined shaft systems for escape. The tunnel ventilation inclined shaft system for escape includes a tunnel, a power fire protection pipe gallery, a vehicle evacuation passage, and a personnel evacuation passage; specifically, a power fire protection pipe gallery, a vehicle evacuation passage, and a personnel evacuation passage are arranged along the depth direction of the tunnel; wherein the vehicle evacuation passage is located in the middle of the tunnel, and the power fire protection pipe gallery and the personnel evacuation passage are symmetrically distributed with the vehicle evacuation passage as the axis.

When a fire occurs, the vehicles and personnel are evacuated separately, and congestion and gathering accidents will not be caused. This design method enables the inclined shaft to have the function of dispersed escape, and solves the technical problem that the ventilation inclined shaft in the traditional tunnel inclined shaft cannot be used as an escape function.

[0043] Inclined shaft ventilation system is one of the important measures used in mining to ensure the safety of the working environment and improve work efficiency, especially in underground mining. Inclined shaft is an inclined passage connecting the ground and underground working surface. The design and operation of its ventilation system are crucial to ensure the quality of underground air, remove harmful gases, control dust, provide fresh air, and adjust the working environment temperature. The following are some basic knowledge of inclined shaft ventilation system. 1. Purpose of ventilation: Remove harmful gases: such as methane, carbon monoxide, sulfur dioxide, etc., to prevent explosions and poisoning accidents. Provide sufficient oxygen: Ensure that there is enough oxygen underground for personnel to breathe and maintain the normal operation of combustion equipment. Control dust: Reduce floating dust in the air and prevent occupational diseases such as pneumoconiosis. Adjust temperature and humidity: Maintain a suitable working environment and improve work efficiency. 2. Ventilation methods include natural ventilation: Use the natural air pressure difference generated by the height difference of the inclined shaft itself for ventilation, which is suitable for shallow wells or small mines. However, this method is greatly restricted by climatic conditions and the effect is unstable. Mechanical ventilation: Install a fan (usually an axial flow fan or a centrifugal fan) to force air supply or exhaust to achieve a stable ventilation effect. It is suitable for deep well or large-scale mining operations, and the air volume can be adjusted as needed. 3. The ventilation network design includes the layout of the main ventilation lanes, auxiliary ventilation lanes and local ventilation facilities to form a reasonable airflow path to ensure that all working faces can be effectively ventilated. It is necessary to consider factors such as wind resistance, wind speed, and air volume distribution, and use ventilation network solving software for simulation analysis to optimize the design plan. 4. In order to control and adjust the direction and volume of wind flow, dampers and wind windows will be set in the shafts. The dampers are used to partition or connect the ventilation paths, and the wind windows are used to fine-tune the air volume. 5. Monitoring and control Use equipment such as anemometers and gas detectors to regularly or continuously monitor the underground air quality, including oxygen concentration, harmful gas concentration, dust concentration, etc. Equipped with an automatic control system, the fan operating parameters are automatically adjusted according to the monitoring data to ensure the efficient and stable operation of the ventilation system. 6. Safety management Establish a strict ventilation management system, including daily inspections of ventilation facilities, maintenance plans, and ventilation adjustment plans in emergency situations.

[0044] It can be seen that the traditional inclined shaft mainly plays the role of ventilation, and the second embodiment of the present invention provides a tunnel system which also serves as a tunnel ventilation inclined shaft system for escape. The tunnel system utilizes the tunnel ventilation inclined shaft system for escape to enable the inclined shaft to have the function of dispersed escape, thereby solving the technical problem that the ventilation inclined shaft in the traditional tunnel 1 cannot be used as an escape function.

[0045] The effective operation of the inclined shaft ventilation system is the basis for ensuring safe production in mines. It requires comprehensive consideration of geological conditions, mining scale, operating characteristics and other factors, and scientific design and meticulous management. It is easy for technicians in this field to understand that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
