Abstract
The utility model is related to wear both wired temperature pier structure of existing railway roadbed under a kind of, both wired above newly-built under-traverse tunnel is arranged in parallel twice for both wired just beams for carrying out holding up reinforcing, just beam end to be supported by buttress, and buttress is located at tunnel both sides；Buttress pier top is provided with sleeper pile.The constructing tunnel structure of the utility model is using subsurface excavation method by if Shed-pipe Advanced Support is aided with grouting with small pipe and carries out pre support.The short drilling depth of in-cavity construction, strong supporting, fast lining cutting, construction safety utmostly reduce the influence to both wired operations, and ensure that both wired construction period does not cut off traffic.
Description
Technical field
The utility model is related to Tunnel Engineering technical fields, and in particular to the both wired of existing railway roadbed is worn under a kind of and is faced
When ruggedized construction.
Background technology
With the Large scale construction of urban rail transit in China, new route wears the situation of existing line increasingly under needing
It is more.The mode of passing through have on wear, under wear and wear three kinds with side, wherein under wear existing railway circuit engineering technology difficulty maximum, risk is most
It is high.During Tunnel Passing existing line, the existing country rock soil body can be generated and disturb and cause stratum deformation, when deformation reaches
The operation security of existing line or even generation damaging influence will be influenced when to a certain degree, correlation will be also influenced when serious
The security of the lives and property of personnel.
The content of the invention
The purpose of this utility model be to provide it is a kind of under wear both wired temperature pier structure of existing railway roadbed, it is ensured that both
Wired operation and construction safety.
Technical solution is used by the utility model：
Both wired temperature pier structure of existing railway roadbed is worn under a kind of, it is characterised in that：
Both wired above under-traverse tunnel is arranged in parallel twice for both wired just beams for carrying out holding up reinforcing, just beam
End is supported by buttress, and buttress is located at tunnel both sides；
Buttress pier top is provided with sleeper pile.
Just the circuit both sides of beam, which are extended, I-steel, and I-steel end is docked with just beam end, I-steel end
It is supported by buttress.
I-steel bottom surface has been evenly arranged sleeper pile.
The utility model has the following advantages：
The utility model is created under-traverse tunnel constructing structure and used to both wired temperature pier measures risen using just corbel
Subsurface excavation method is by if Shed-pipe Advanced Support is aided with grouting with small pipe and carries out pre support.The short drilling depth of in-cavity construction, strong supporting, fast lining cutting are applied
Work safety utmostly reduces the influence to both wired operations, and ensures that both wired construction period does not cut off traffic.

Specific embodiment
The utility model is described in detail With reference to embodiment.
The utility model is related to it is a kind of under wear both wired temperature pier structure of existing railway roadbed, on newly built tunnels
Side it is both wired be arranged in parallel twice for both it is wired carry out hold up reinforcing just beam 1, just 1 end of beam supported by buttress 4, prop up
Pier 4 is located at tunnel both sides；4 pier top of buttress is provided with sleeper pile 3.
Just the circuit both sides of beam 1, which are extended, I-steel 2, and 2 end of I-steel is docked with just 1 end of beam, I-steel 2
End is supported by buttress 4；2 bottom surface of I-steel has been evenly arranged sleeper pile 3.
Embodiment：
Existing railway Roadbed Soil is worn under tunnel exit, vault is away from the high about 5.5m of existing railway rail level, using following measures：
1st, both wired using the widened D types of 2 hole 24m, just beam 1 holds up reinforcing, and carries out button rail to both wired, just 1 base of beam
Plinth uses the caisson of φ 120cm, i.e. buttress 4, digging hole pile foundation should go deep into complete basement rock 2m.
2nd, banket existing line base using grouting and reinforcing.φ 42mm ductules, 4 ~ 6m of length, 1.0 × 1.0m of spacing, plum
Flower pattern is arranged, notes single liquid cement mortar.
3rd, construction is worn under creating using subsurface excavation method by if Shed-pipe Advanced Support is aided with grouting with small pipe and carries out pre support.In hole
Construction has to do things steadily and surely, short drilling depth, strong supporting, fast lining cutting.
4th, strengthen deformation monitoring measure, including being restrained in surface subsidence and hole, especially to strengthen both wired rail level absolute altitude,
The measurement of gauge etc. will take the measures such as parking, reinforcing, it is ensured that both wired operation and construction safety immediately if any abnormal.
The content of the utility model is not limited to cited by embodiment, and those of ordinary skill in the art are new by reading this practicality
Type specification and to any equivalent conversion that technical solutions of the utility model are taken, be the claim institute of the utility model
Cover.
