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.

The Tunnel Second Lining of the utility model is included in after the completion of Tunnel, cuts part temporary support coagulation Soil cuts thickness and is adapted with Second Lining Construction required thickness, and retains bracing members, segmentation installation secondary lining reinforcing bar, mould Plate, holder, casting concrete.
The tunnel waterproofing layer of the utility model is included in after completion secondary lining, form removal, cuts all interim branch Concrete is supportted, interim profile steel frame, repairing leveling secondary lining concrete surface are cut off, installation overlays waterproof roll.
The lining cutting three times of the utility model includes the lining cutting of construction inverted arch, arch wall lining cutting, inverted arch fill concrete, and described faces upward Arch lining block is included in section bottom and overlays waterproof roll, surface installation lining cutting reinforcing bar three times, erects template, casting concrete, Steel plate water stopper is set in the middle part of the construction joint of side wall lining longitudinal direction;The inverted arch fill concrete, which is included in inverted arch bottom and pours, to be filled out Fill concrete;The arch wall lining cutting includes that lining cutting reinforcing bar, use are whole three times along waterproof roll surface setting tunnel arch wall is overlay Body formula lining trolley construction lining concrete three times.
The utility model has the following advantages compared with the existing technology:
1, tunnel cross-section is small, and construction is smaller to the disturbance on stratum.
2, bored tunnel mostly uses horseshoe type, oblate type, and circular cross section stress is evenly.
3, 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.
4, 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.
