[0033] The utility model provides a through-type service tunnel with the functions of auxiliary construction, ventilation, drainage and rescue, which achieves the purpose of assisting the ventilation and drainage of the mainline tunnel construction, ensuring the ventilation and drainage of the operation, and ensuring the safety of the personnel in the tunnel in case of fire or emergency.

[0034] like Figure 1 , the direction of the left-line tunnel 1 and the right-line tunnel 6 in the figure is defined as the longitudinal direction, and the direction perpendicular to the direction of the left-line tunnel 1 and the right-line tunnel 6 is the transverse direction. The through-type service tunnel is set up between the left-line tunnel 1 and the right-line tunnel 6, including the left-line cross channel 2, the vertical shaft 3, the service channel 4 and the right-line cross channel 5. The service channel 4 is set up longitudinally between the left-line tunnel 1 and the right-line tunnel 6, and is set up along the entire line, and is connected to the vertical shaft 3 at the top. The left-line cross channel 2 is laterally connected between the left-line tunnel 1 and the service channel 4, and the right-line cross channel 5 is laterally connected between the right-line tunnel 6 and the service channel 4.

[0035] The vertical shaft 3 can directly utilize the existing structure during the tunnel construction. The position of the vertical shaft 3 corresponds to the node where the left-line cross channel 2 connects to the service channel 4 or the node where the right-line cross channel 5 connects to the service channel 4. Multiple locations are set at intervals. The lateral distance between the service channel 4 and the left-line tunnel 1 and the right-line tunnel 6 is roughly the same.

[0036] Figure 1 In the middle, the left-line transverse channel 2 and the right-line transverse channel 5 are staggered front and back longitudinally to avoid the transverse channels on both sides of the service channel 4 to correspond horizontally and the ventilation on both sides to affect each other.

[0037] like Figure 2 The service channel 4 is set lower than the left-line tunnel 1 and the right-line tunnel 6, and the left-line transverse channel 2 and the right-line transverse channel 5 are respectively connected to the service channel 4 obliquely downward from the left-line tunnel 1 and the right-line tunnel 6. The utility model has a drainage function, and the oblique downward transverse channel is more conducive to drainage.

[0038] The structure of the service channel 4 can adopt a general tunnel structure with a lining and a drainage system, such as longitudinal side ditches 8 on both sides of the bottom and a longitudinal central ditch 9 in the center of the bottom. An annular pipe is arranged in the lining structure of the service channel 4, and the bottom end of the annular pipe is connected to the side ditch 8. The side ditch 8 is connected to the central ditch 9 through a transverse connecting pipe, and the side ditch itself has a drainage function.

[0039] A transverse channel center ditch is arranged at the center of the bottom of the left-line transverse channel 2 and the right-line transverse channel 5 for channel drainage. The transverse channel center ditch can be connected to the center ditch 9 for confluence and discharge.

[0040] like Figure 3 Fans 7 are arranged on both sides of the service channel 4, and fans 7 are arranged on both sides of the left-line horizontal channel 2 and the right-line horizontal channel 5, all of which are installed on fan brackets.

[0041] During the construction period, the service tunnel of the utility model can be used as a through-level guide to assist in construction, increase the construction working surface, and assist in tunnel construction ventilation and construction drainage.

[0042] During operation, fans and valves are installed in the service channel 4 and the cross channel as needed. The service tunnel of the utility model is used as a ventilation duct. Based on the fan to guide the airflow, a segmented ventilation mode is formed for operational ventilation to ensure the air quality in the main line.

[0043] For tunnels in severe cold and cold areas, the service tunnel of the utility model can be used as a drainage tunnel to avoid freezing damage such as ice hanging in the tunnel and siltation in the drainage ditch.

[0044] When a fire or emergency occurs in the main line tunnel, personnel can quickly escape into the service channel through the cross channel to ensure the safety of personnel in the tunnel.

[0045] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
