Technical field
This utility model belongs to shield tunnel class field, is specifically related to the pipe-plate lining structure of a kind of blood pressure lowering that sluices.
Background technology
Pipe-plate lining ring is the structural shape that one is widely used in shield (TBM) tunnel, is that a kind of waterproof effect is preferable
Tunnel structure pattern, typically before tunnel piercing, be prefabricated into pipe-plate lining block by batch production, assembled cyclization in shield machine, pipe
Waterproof elastic rubber gasket is set between tile and block, between ring and ring.Then release shield tail, bear the various of tunnel
Load.Owing to shield tunnel digs driving, it is therefore desirable to space after pipe-plate lining wall is carried out grouting and reinforcing, it is ensured that shield tunnel
Stability.
When pipe-plate lining tunnel structure is applied to high hydraulic condition, on the one hand use as made structure bear water pressure completely
Thicker tunnel segment structure, uneconomical；On the other hand, elastic sealing gasket is easy seepage under long-term high hydraulic pressure effect, affects tunnel
Safe operation.It is to open relief hole reserved on the ring of section of jurisdiction to high penstock sheet built existing sluicing reduction technology, will lining
Build the subsoil water after wall by relief hole pressure limiting draining.In actual application, there is following asking in existing sluicing buck configuration
Topic:
(1) relatively low due to the grouting layer infiltration coefficient after pipe-plate lining wall, subsoil water is not smooth toward the path of spilled water hole seepage flow,
Cause water discharging structure can only reduce the hydraulic pressure near spilled water hole, and the water pressure at other position of pipe-plate lining ring away from spilled water hole
The biggest, it is difficult to reach the purpose of tunnel all-round sluicing blood pressure lowering.
(2) spilled water hole needs to carry out slip casting, during serosity easily blocks in spilled water hole, and grouting layer during slip casting behind
The fine graineds such as fine sand easily move under long-term high hydraulic pressure effect, thus block sluicing decompression hole, after causing runing a period of time
Spilled water hole occurs cannot the problem of draining.

Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, it is simple to is well understood to
This utility model, but they do not constitute restriction to this utility model.
As it is shown in figure 1, this utility model provides the pipe-plate lining structure of a kind of blood pressure lowering that sluices, including pipe-plate lining ring,
It is characterized in that: pipe-plate lining ring is included coaxially being spliced by the fissure of displacement and multiple lets out according to what certain intervals was longitudinally arranged along tunnel
Water decompression tube sheet built ring 5 and fixing pipe-plate lining ring 6, at least set between one group of adjacent sluicing decompression tube sheet built ring 5
It is equipped with fixing pipe-plate lining ring 6；At least it is provided with sluicing decompression tube sheet built between one group of adjacent fixing pipe-plate lining ring 6
Ring 5；Sluicing decompression hole 3 through after oriented pipe-plate lining ring wall is set on sluicing decompression tube sheet built ring 5；Sluicing decompression hole 3
Inwall on be provided with air relief valve 4；It is filled with the water guide with hole after sluicing decompression tube sheet built ring 5 wall and between country rock 1
Layer 7.Sluicing decompression hole is arranged at the drainage channel of tunnel longitudinal direction, it is simple to Quick drainage after spilled water hole startup, and does not affects
The use function in tunnel.Described water guide layer thickness meets it and forms good drainage path in pipe-plate lining ring periphery, once opens
Dynamic blood pressure lowering sluices, it is possible to quickly reduce the water pressure in tunnel.
It is connected by grouting layer 2 is fixing with country rock 1 after the wall of described fixing pipe-plate lining ring 6, fixing pipe-plate lining ring 6 wall
The modes such as rear employing slip casting backfill closely knit with country rock 1.The thickness of pipe-plate lining ring 6 grouting behind shaft or drift lining layer ensures pipe-plate lining ring and tunnel
Effectively fixing of road country rock, limits the deformation of pipe-plate lining ring.
Described water guide layer 7 uses the material that the infiltration coefficients such as beans stone are higher to fill and is formed.The particle diameter model of described beans stone
Enclosing for 5-10mm, the injected hole reserved from pipe-plate lining ring of described beans stone is blown into, and its bean footpath size should be easy to construction.
The plurality of sluicing decompression tube sheet built ring 5 and the alternately arranged assembled connection of fixing pipe-plate lining ring 6, by deformation
Coordinate to keep the Stability Analysis of Structures of sluicing blood pressure lowering ring.Water guide layer 7 along sluicing decompression tube sheet built ring 5 outer wall contour line loopful or
Every being evenly arranged, determine according to permeability, groundwater condition and the Operational requirements on stratum residing for tunnel.
When hydraulic pressure is close to when bearing the limit of seam elastic sealing gasket, pipe-plate lining and construction equipment, open air relief valve 4,
Sluicing decompression hole 3 starts to sluice, and owing to water guide layer 7 infiltration coefficient is high, the water pressure of tunnel perimeter can be reduced rapidly to and sluice
At decompression hole 3 mouthfuls basically identical.Owing to sluicing decompression tube sheet built ring 5 does not the most carry out the filtration work of slip casting and beans stone
With, it is possible to prevent spilled water hole blocked.The water guide layer 7 material hole filled behind due to sluicing decompression tube sheet built ring 5 is relatively big,
More weak to tunnel structure effect of contraction, easily produce tunnel structure deformation bigger.But use note after fixing pipe-plate lining ring 6 wall
Slurry mode forms stable structure, and sluicing decompression tube sheet built ring 5 and fixing pipe-plate lining ring 6 use the side of staggered joint erection simultaneously
Formula reaches compatibility of deformation, and the deformation of sluicing decompression tube sheet built ring 5 and stress are transferred to stable fixing pipe-plate lining ring
6, thus it is collectively forming stable overall structure.
The content that this specification is not described in detail belongs to prior art known to professional and technical personnel in the field.
