Description
Technical field
The utility model belongs to technical field of tunnel construction, and in particular to arrives a kind of circular cross section tunnel lining construction three times
Device.
Background technology
In the construction of city underground shallow-depth-excavation tunnel, liner structure generally uses secondary liner structure, i.e. once lining
(preliminary bracing structure)+secondary lining (reinforced concrete lining layer), and waterproof layer is set among once lining and secondary lining.
But in tunnel excavation support, due to hydrogeologic condition limitation (level of ground water height, geology country rock difference etc.) or construction ring
Border condition element influences (buried depth is shallow, above ground structure is intensive etc.), to ensure tunnel excavation safety, generally uses temporary support
System adds interim median septum or interim inverted arch in CD or CRD methods.
In Tunnel Second Lining structure construction, general using bottom inverted arch of first constructing, re-segmenting removes temporary support
System, segmentation installation waterproof layer, the secondary armored concrete liner structure of construction.Especially in circular cross section tunnel, inverted arch filling
Layer structure is very thin, can not only remove temporary supporting system safely after the completion of inverted arch is constructed.
Therefore when the circular tunnel section for being provided with temporary supporting system carries out Tunnel Second Lining structure construction, generally
It is that construction period is very long, speed is slower, and process interference is big, and effect is low.
