Abstract
The utility model relates to a slope collapse rock prevention open-cut tunnel structure for multi-line unequal-altitude railways, which can effectively solve the problems of difficulty of unequal-altitude joint repair and affection on collapse rock prevention caused by incompleteness of respective repair and protection so as to guarantee running safety of tunnels. An open-cut tunnel mainly comprises an arch portion lining (11), an inner side wall lining (12), an outer side wall lining (13) and a backfilling layer, wherein the backfilling layer is filled outside the open-cut tunnel. An actual backfilling line (24) on one side of the backfilling layer close to a slope surface of a side slope is recessed relative to a devised backfilling line (25) to form a collapse rock channel (26), a side slope protection net (31) is fixedly arranged on the slope surface of the side slope above the open-cut tunnel, and a protective guard (32) is fixedly arranged on the top of the outer side wall lining (13).
Description
Technical field
The utility model relates to railway tunnel, particularly a kind of multi-thread high railway abrupt slope danger stone control open cut tunnel structure that do not wait
Background technology
Mostly the mountain area, southwest especially Guizhou and area, Guangxi is karst landform, and landform is precipitous, and the crag falling rocks is grown.Along with people-oriented, the theory of safety first deepens continuously, the control of railway crag falling rocks is also paid attention to more.In recent years along with the road network construction to mountain development, often form multi-thread parallel general layout, multi-thread parallel and rail level does not wait under the high situation control of crag falling rocks more difficult.
For high situation such as multi-thread parallel rail levels, generally can adopt the multi-thread scheme control crag falling rocks that closes honest and enlightened hole or hangar tunnel; And for multi-thread parallel but rail level does not wait high situation; The circuit span and the discrepancy in elevation that it is adjacent are all bigger; Be difficult to through building open cut tunnel or the hangar tunnel structure is protected, falling rocks very easily occur, have a strong impact on the operation security of subordinate's railway from the risk that the higher level divides the open cut tunnel top spring of repairing to get into subordinate's railway.
The utility model content
The utility model technical problem to be solved provides a kind of multi-thread high railway abrupt slope danger stone control open cut tunnel structure that do not wait, and can effectively separate and never wait high closing to repair difficulty and branch and repair and protect the endanger problem of stone prevention effect of overall effect not, to guarantee the tunnel operation security.
It is following that the utility model solves the technical scheme that its technical problem adopted:
The multi-thread high railway abrupt slope danger stone control open cut tunnel structure that do not wait of the utility model; The open cut tunnel main body comprises that arch lining cutting, inner edge wall lining are built and the outside wall lining is built; And fill the backfill layer outside it; It is characterized in that: said backfill layer near the actual backfill line of side slope surface one side with respect to the recessed formation stone falling channel of engineered fill line, on the side slope surface above the open cut tunnel, fixedly install the side slope protection net, the top of abutment wall lining cutting outside fixedly installs roll guard.
The beneficial effect of the utility model is; Multiple-protection is set, falling rocks is carried out effective classification interception, avoid falling rocks to get into low class 1 railroad; Separate effectively and never wait high closing to repair difficulty and branch and repair and protect the not difficult problem of overall effect danger stone prevention effect, thereby guarantee the tunnel operation security.
Description of drawings
This manual comprises like next width of cloth accompanying drawing:
Fig. 1 is the multi-thread sectional schematic diagram that does not wait high railway abrupt slope danger stone control open cut tunnel structure of the utility model.
Member shown in the figure, toponym and pairing mark: arch lining cutting 11, inner edge wall lining block 12, outside wall lining build 13; The 1st backfill layer the 21, the 2nd backfill layer the 22, the 3rd backfill layer 23, actual backfill line 24, engineered fill line 25, stone falling channel 26; Side slope protection net 31, the roll guard 32 on the open cut tunnel exterior wall.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
With reference to Fig. 1, the multi-thread high railway abrupt slope danger stone control open cut tunnel structure that do not wait of the utility model, the open cut tunnel main body comprises arch lining cutting 11, inner edge wall lining block 12 and outside wall lining block 13, and fills the backfill layer outside it.Said backfill layer near the actual backfill line 24 of side slope surface one side with respect to engineered fill line 25 recessed formation stone falling channels 26; On the side slope surface above the open cut tunnel, fixedly install side slope protection net 31, the top of abutment wall lining cutting outside 13 fixedly installs roll guard 32.Multiple-protection is set; Falling rocks is carried out classification interception, with side slope protection net 31 as the first road safeguard procedures, with the 26 second road safeguard procedures of the stone falling channel on the backfill face; Stone falling channel 26 ability effectively catching part falling rocks; The falling rocks that part spring is not gone in the groove protect by roll guard 32 once more, separates effectively and never waits height to close to repair difficulty and branch to repair to protect not the overall effect difficult problem of stone prevention effect of endangering, thereby guarantee the tunnel operation security.
With reference to Fig. 1, usually, said backfill layer comprises filling in arch lining cutting 11 and outside wall lining builds the 1st backfill layer 21 between 13, fills the 2nd backfill layer 22 between inner edge wall lining block 12 and side slope surface, fills 3rd backfill layer 23 of lining cutting more than 11 in the arch.The 1st backfill layer 21 is filled by the C20 concrete, and the 2nd backfill layer 22 is filled by mortar flag stone, and the 3rd backfill layer 23 is filled by native stone.
Not waiting the danger stone control of high location with reconstruction iron Hunan and Guangxi line WDK365+555～WDK365+613 section abrupt slope below is that embodiment further specifies the utility model.WDK365+555～WDK365+613 section is the parallel locations of four lines, and the upper level step is the outer left line of goods, and the next stage step is the outer right line of Hunan and Guangxi main track and goods, and abrupt slope, the outer left line left side of goods is a dolomitic limestone, and the discrepancy in elevation reaches hundred meters, and danger stone is grown.Concrete parameter is following:
1, the outer left line of goods is taked the single line open cut tunnel, and the open cut tunnel liner structure is made up of arch lining cutting 11, inner edge wall lining block 12, outside wall lining block 13, inverted arch lining cutting 14.Wherein the outside wall lining is built 13 overhead roll guards 32, and the outside wall lining is built 13 structural thicknesses and should give reinforcement.
2, open cut tunnel structure backfill layer comprises the 1st backfill layer 21 that fills between arch lining cutting 11 and outside wall lining block 13, fills the 2nd backfill layer 22 between inner edge wall lining block 12 and side slope surface, fills 3rd backfill layer 23 of lining cutting more than 11 in the arch.Wherein actual backfill line 24 should stay stone falling channel 26, and object is answered periodic cleaning in the stone falling channel 26, is no more than engineered fill line 25.
3, protective screening 31 is set on the abrupt slope, the outside wall lining is built 13 tops and is fixedly installed roll guard 32, and falling rocks is carried out effective classification interception.
Multi-thread some principles that do not wait high railway abrupt slope danger stone control open cut tunnel structure of the above the utility model that just explains through diagrams; Be not be to the utility model be confined to shown in described concrete structure and the scope of application in; So every the modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
