Abstract
The utility model belongs to the field of a lining structure for rail tunnels and relates to a permanent lining structure for tunnels in an active fault section. In past railway location, a basic principle of railway location for the active fault section is that the active fault section is kept off as far as possible, and if the active fault is not kept off, only the general engineering (lower roadbeds or culverts) of railway passes through the active fault section in the form of a large angel and a short distance so as to reduce construction of tunnel in the active fault section; therefore, the permanent lining structure is specially important when the tunnels are constructed in the active fault section in tunnel engineering. The permanent lining structure adopts the form of a circular section structure with high quake-proof capacity; deformed continuous seams which vertically partitions the tunnels are separately formed in the permanent lining structure, so as to form a structure system which eliminates deformation and releases seismic energy section by section. Due to high quake-proof capacity, the permanent lining structure forms a reparable structure through twice structure forms after the tunnel is partially damaged by earthquake, so as to ensure rapid repair, thereby reducing the damage to the tunnel engineering as much as possible when the fault moves due to the earthquake.
Description
Technical field
The utility model belongs to railway tunnel lining structure field, relates to tunnel, activity tomography location permanent lining, secondary lining structure.
Background technology
Said activity tomography generally was meant since the Recent Epoch (about 10,000 years) on the engineering, and movable tomography once took place.When passing through, infer that from its occurrence frequency in the phase, differential settlement, craze and transfiguration and bad break might take place for it at engineering safety, can directly influence the normal use of engineering when serious, even cause disaster when setting on active fault or with engineering.Therefore, in railway route selection in the past, when meeting with the activity tomography, basic route selection principle is firmly to pass round can pass round the time, must wide-angle in the time of can not passing round, short distance passes through with common engineering (low roadbed or culvert), and it is less to pass through example with construction of tunnel.So build construction of tunnel at the activity tomography, the permanent lining, secondary lining structure is with regard to particular importance.
Summary of the invention
The purpose of this utility model is to provide a kind of tunnel, activity tomography location permanent lining, secondary lining structure with safe and reliable, advanced technology and economic and reliable.
For achieving the above object, the technical solution adopted in the utility model is:
Tunnel, activity tomography location permanent lining, secondary lining structure, its special character is: described permanent lining, secondary lining structure adopts the high circular cross section form of structure of shock resistance; The distortion straight joint that the tunnel is vertically carried out piecemeal is set in the permanent lining, secondary lining structure at interval, forms the structural system that segmentation absorbs distortion and discharges seismic energy.
Above-mentioned permanent lining, secondary lining structure adopts double-deck steel concrete, but is formed on the maintaining structure after the earthquake local failure, guarantees quick reparation.
Above-mentioned tunnel cross-section apply fill concrete layer and groove at the bottom of the tunnel, reinforcement concrete structure layer also is set outside reinforced concrete floor.
The utility model is with respect to prior art, and its advantage is as follows:
Can cause the permanent lining, secondary lining structural deterioration to peripheral rock kneading extruding when 1, considering faulting, select the high circular cross section form of structure of shock resistance;
2, at interval the distortion straight joint is set, the tunnel is vertically divided soon, form the structural system that segmentation absorbs distortion and discharges seismic energy;
3, the permanent lining, secondary lining structure adopts and applies for twice, but is formed on the maintaining structure after the earthquake local failure, guarantees quick reparation.
4, consider the activity tomography in quite long period, still have distortion slowly, therefore, in tunnel structure, estimated total deformation, reserve in level, vertical direction by 100 year useful life period.
Description of drawings
Fig. 1 is a three-dimensional structure diagram of the present utility model;
Fig. 2 is an assembling schematic diagram of the present utility model.
The specific embodiment
Referring to Fig. 1, Fig. 2, existing liner structure is an elliptical section form of structure, tunnel cross-section size and technical standard are directly related, therefore should get technical standard in conjunction with actual engineering determines cross dimensions, then according to engineering pass through the technical data of activity tomography, determine the level of Tunnel Design lifetime, vertically add up displacement, thereby determine the pre-allowance of distortion.
Permanent lining, secondary lining structure of the present utility model adopts the high circular cross section form of structure of shock resistance; The distortion straight joint that the tunnel is vertically carried out piecemeal is set in the permanent lining, secondary lining structure at interval, forms the structural system that segmentation absorbs distortion and discharges seismic energy.
Referring to Fig. 2, its permanent lining, secondary lining structure adopts double- deck steel concrete 1,2, but is formed on the maintaining structure after the earthquake local failure, guarantees quick reparation.
After the tunnel cross-section excavation is shaped, apply reinforced concrete floor 1 earlier, lagging behind suitably applies reinforced concrete floor 2 after the distance, and reinforced concrete floor 2 adopts the perfusion of circular shuttering chassis pumping of concrete; After this apply fill concrete layer 3 and groove 4 at the bottom of the tunnel successively, reinforcement concrete structure layer 5 also is set outside reinforced concrete floor 2.
Consider the activity tomography in quite long period, still have distortion slowly, therefore, in tunnel structure, estimated total deformation, reserve in level, vertical direction by 100 year useful life period.
Claims (3)
1, tunnel, activity tomography location permanent lining, secondary lining structure is characterized in that: described permanent lining, secondary lining structure adopts the high circular cross section form of structure of shock resistance; The distortion straight joint that the tunnel is vertically carried out piecemeal is set in the permanent lining, secondary lining structure at interval.
2, tunnel, activity tomography location according to claim 1 permanent lining, secondary lining structure, it is characterized in that: described permanent lining, secondary lining structure adopts double-deck steel concrete (1,2).
3, tunnel, activity tomography location according to claim 1 permanent lining, secondary lining structure, it is characterized in that: described tunnel cross-section apply fill concrete layer (3) and groove (4) at the bottom of the tunnel, reinforcement concrete structure layer (5) also is set outside reinforced concrete floor (2).
