Abstract
The invention provides a railway tunnel protection structure crossed with a water passing tunnel, which comprises piles, a reinforced concrete bottom plate and curtain grouting; the piles are vertically fixed on two sides of the railway tunnel, reinforced concrete bottom plates are poured on the tops of the piles, the water passing tunnel is fixed by taking the reinforced concrete bottom plates as supports, and curtains are radially arranged on the position, located on the side face of the reinforced concrete bottom plate, of the water passing tunnel for grouting. The reinforced concrete bottom plate reduces the influence of train vibration of the railway tunnel and disperses the pressure of surrounding rocks at the upper part, and the water passing tunnel is radially provided with a row of curtains at the front and the back of the cross section for grouting, so that the influence of water leakage during the operation of the water passing tunnel is reduced. The protective structure effectively solves the problem that the water passing tunnel and the railway tunnel are mutually influenced at the cross position, the axis of the water passing tunnel is straight, the water flow condition is good, the structure is simple, and the design and construction difficulty is small.
Description
Technical field
The present invention relates to a kind of railway tunnel safeguard structures intersected with water tunnel, belong to subterranean railway tunnel protection knot
Structure technical field.
Background technique
During water conservancy construction, part engineering can be related to the case where water tunnel intersects with railway tunnel, railway tunnel
Road can not be synchronous with the water tunnel construction period, the two spatial position close proximity, seepage effect railway during water tunnel is runed
Tunnel operation security, railway tunnel train vibration influence water tunnel safety, and traditional scheme is mainly that water tunnel is relocated and fallen
Siphon has pressure underpassing scheme, is staggered and railway tunnel is intersected, but water tunnel relocates and increases tunnel length, and the program is handed over
Vent sets elevation limitation；Inverted-siphon has pressure underpassing scheme that control lock is arranged before inclined tube, and control lock chamber builds access tunnel and leads to mountain
In vitro, complex structural designs, Sedimentation Problems are relatively difficult to resolve certainly, and later period operation and maintenance cost is high.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of railway tunnel safeguard structure intersected with water tunnel,
The railway tunnel safeguard structure intersected with water tunnel can solve water tunnel and railway tunnel and influence each other in crossover location,
Water tunnel flow condition is bad, design, the problem of difficulty of construction is big.
The present invention is achieved by the following technical programs.
A kind of railway tunnel safeguard structure intersected with water tunnel provided by the invention, including stake, armored concrete bottom
Plate, grout curtain；The stake is vertically fixed on the two sides of railway tunnel, and stake top portion casting reinforced concrete bottom plate is mixed with reinforcing bar
Solidifying soil bottom plate is to support fixed water tunnel, and the position that reinforced concrete floor side is located on water tunnel is arranged radially curtain
Grouting.
The diameter of the stake is 2m.
The stake is 2m at a distance from railway tunnel.
The stake spacing ipsilateral in railway tunnel is 2m.
The reinforced concrete floor with a thickness of 2m.
The setting positional distance reinforced concrete floor at least 10m of the grout curtain.
The laying length of the stake is 1.5 times or more of water tunnel width and is not less than 10m.
The water tunnel is excavated using shield machine or tunnel boring machine.
The beneficial effects of the present invention are: reinforced concrete floor reduces in railway tunnel train vibration influence and dispersion
Portion's pressure from surrounding rock, water tunnel are arranged radially row's grout curtain before and after transposition section, seep during reducing water tunnel operation
The influence of leak.The safeguard structure efficiently solves water tunnel and railway tunnel and influences each other in crossover location, crosses water tunnel
Hole axis is more straight, and flow condition is good, and structure is simple, and design, difficulty of construction are small.
Detailed description of the invention
Fig. 1 is cross-sectional configuration schematic diagram of the invention；
Fig. 2 is longitudinal plane structure schematic diagram of the invention.
In figure: 1- water tunnel, 2- railway tunnel, 3-, 4- reinforced concrete floor, 5- grout curtain.
Specific embodiment
Be described further below technical solution of the present invention, but claimed range be not limited to it is described.
A kind of railway tunnel safeguard structure intersected with water tunnel as shown in Figure 1 and Figure 2, including stake 3, reinforced concrete
Native bottom plate 4, grout curtain 5；The stake 3 is vertically fixed on the two sides of railway tunnel 2,3 top pouring reinforced concrete floor of stake
4, it is to support fixed water tunnel 1 with reinforced concrete floor 4, the position of 4 side of reinforced concrete floor is located on water tunnel 1
It sets and is arranged radially grout curtain 5.
The diameter of the stake 3 is 2m.
The stake 3 is 2m at a distance from railway tunnel 2.
Stake 3 spacing ipsilateral in railway tunnel 2 is 2m.
The reinforced concrete floor 4 with a thickness of 2m.
The 4 at least 10m of setting positional distance reinforced concrete floor of the grout curtain 5.
The laying length of the stake 3 is 1.5 times or more of 1 width of water tunnel and is not less than 10m.
The water tunnel 1 is excavated using shield machine or tunnel boring machine.
Intersect when it is implemented, the present invention is suitable for water tunnel 1 with railway tunnel 2, and the two spatial position is at a distance of very
Nearly situation, intersection section front and back 10m range use pile slab structure, and railway tunnel two sides interval 2m distance piling 3, stake top position pours
Reinforced concrete floor 4, pile slab structure support top water tunnel 1, and reinforced concrete floor 4 reduces 2 train of railway tunnel
Vibration influences and dispersion top pressure from surrounding rock, water tunnel 1 are arranged radially row's grout curtain 5 before and after transposition section, reduce
The influence of percolating water during water tunnel 1 is runed.
Work progress is as follows:
1, water tunnel is always about 2km, cross dimensions D=8m, and tunnel excavation uses shield machine (TBM), saves the duration；
2, it drives piles in the water tunnel after excavating along railway tunnel two sides, stake diameter is 2m, and spacing 2m, stake top position pours
Reinforced concrete floor, bottom plate thickness 2m, the gap between water tunnel and bottom plate backfill slightly expanded concrete；
3, row's grout curtain is arranged radially in water tunnel at 50m before and after intersection section.
