Embodiment Construction
[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0033] see figure 1 As shown, a construction method for joint construction of station air duct and underground excavation section includes the following steps:
[0034] Step 1, constructing the shaft 1 of the fresh air shaft;
[0035] Step 2, constructing the connecting section structure 2 between the shaft and the air duct;
[0036] Step 3, constructing the station air duct structure 3, which is located above the main line of the station section;
[0037] Step 4, construct the second lining structure 4 of the fresh air shaft, and complete the air duct air defense section structure 41 after the second lining structure 4 of the fresh air shaft is completed;
[0038] Step 5, construction exhaust shaft shaft 5;
[0039] Step 6, constructing the structure 6 of the connecting section between the exhaust shaft and the air duct.
[0040] Among them, see figur...
