Structure (16)；Construction station internal structure, station main body civil construction are completed.
In the present embodiment, temporary construction vertical shaft and transverse passage-way can be excavated with construction site on ground, in the transverse passage-way of upper layer
The small pilot tunnel in station is set, arch tube curtain (being divided into big pipe curtain tubule curtain by internal diameter difference) structure is set in lower layer's transverse passage-way,
Laying freezing pipe forms the Frozen Soil Cylinder being used cooperatively with pipe curtain structure in pipe curtain.
In the present embodiment, this method is suitable for building for the buried Station of water rich strata, the tunneling vehicle in water rich strata
It stands in construction process, can avoid influence of the Underground Construction to traffic above-ground and pipeline, while avoiding traditional subsurface excavation method station
The larger bring groundwater treatment problem of buried depth.
In the present embodiment, big pipe curtain (5), tubule curtain (6) and Frozen Soil Cylinder (8) form domes can to resist foundation soil anti-
Power and water buoyancy form closing water-stop curtain with water barrier and the lateral building enclosure of hidden digging structure (9), guarantee anhydrous job execution
Condition.
In the present embodiment, it is not necessarily to ground artificial precipitation, by arranging freezing pipe (7) in pipe curtain, to pipe curtain week in construction
Side rich water soil layer, which actively freezes, forms Frozen Soil Cylinder (8), forms closing water-stop curtain with the lateral building enclosure of hidden digging structure (9).
In the present embodiment, the small pilot tunnel in upper layer (4) is for the structures such as the lateral building enclosure in station (9), steel pipe column (10) of constructing；
When the small pilot tunnel in upper layer (4) is located at water level line or less and is unable to dewatering construction, according to Practical Project using slip casting or freezing sealing
Measure.
In the present embodiment, tubule curtain (6) is mainly arranged in arch structure span centre position, plays connection and intermal force, and diameter
Meet construction personnel's working space requirement；Big pipe curtain (5) is used as arch structure fulcrum force, and also serve as hidden digging structure vertical applied force
Member base, it is ensured that arch tube curtain structure forms complete structure stress system with tunneling main structure, guarantees structure safety,
Its diameter need to meet foundation bearing capacity and construction personnel's working space requirement.
In the present embodiment, big pipe curtain (5) is used as vertical applied force member base, when foundation bearing capacity is unsatisfactory for requiring, in advance
Injected hole is stayed, grouting and reinforcing is carried out to ground, improves foundation bearing capacity.
In the present embodiment, big pipe curtain (5) also serves as lateral building enclosure (9) strip footing and steel pipe as arch structure fulcrum again
Strip footing under column (10) guarantees structural system integrality, while realizing underwater operating machine and melting digging.
