Description
Technical field
The invention belongs to technical field of tunnel construction, and in particular to a kind of circular cross section tunnel lining construction side three times
Method.
Background technology
In the construction of city underground shallow-depth-excavation tunnel, liner structure is generally using 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 using temporary support
System in CD or CRD methods, adds interim median septum or interim inverted arch.
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.Particularly in circular cross section tunnel, inverted arch filling
Layer structure is very thin, only can not remove temporary supporting system safely after the completion of inverted arch construction.
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.

Concrete, cuts off interim profile steel frame, repairing leveling secondary lining concrete surface, and installation overlays waterproof roll.
The lining cutting three times of the present invention includes the lining cutting of construction inverted arch, arch wall lining cutting, inverted arch fill concrete, inverted arch lining
Block is included in section bottom and overlays waterproof roll, surface installation lining cutting reinforcing bar three times, erects template, casting concrete, in abutment wall
Setting steel plate water stopper in the middle part of the construction joint of lining cutting longitudinal direction；The inverted arch fill concrete is included in inverted arch bottom, and to pour filling mixed
Solidifying soil；The arch wall lining cutting is included along waterproof roll surface setting tunnel arch wall lining cutting reinforcing bar three times is overlay, using monoblock type
Lining trolley construction lining concrete three times.
The present invention has the following advantages relative to the prior art：
1st, tunnel cross-section is small, constructs smaller to the disturbance on stratum.
2nd, bored tunnel is mostly using horseshoe type, oblate type, and circular cross section stress is evenly.
3rd, it is designed relative to two layers of liner structure, three layers of liner structure design can be complete in second layer reinforced concrete lining layer
Cheng Houke, which shifts to an earlier date, all removes temporary support, and speed of application is relatively faster.
The 4th, waterproof layer is set between second layer lining cutting and third layer lining cutting, waterproof layer laying basal plane is more smooth, more sharp
In the construction quality of control waterproof layer, ensure the construction quality of entire circular cross section.
