Description
Technical field
The present invention relates to a kind of shield tunnel construction, be specifically related between a kind of shield tunnel chip architecture and section of jurisdiction connect knot
The design of structure.
Background technology
In recent years, along with the reinforcement putting into infrastructure construction, urban infrastructure cause achieves fast development.With
This simultaneously, the tunnel previously built, run through for many years, shield tunnel construction occur in that longitudinal differential settlement, transversely deforming,
The disease problems such as long-term seepage, joint infringement, crackle crack, section of jurisdiction, reduce tunnel military service quality, cause to operation security
Certain threat.
At present, shield tunnel construction typically uses inner bolt between reinforced concrete segment erection method, section of jurisdiction to connect, connect
Seam uses elastic sealing gasket or expanded rubber bar waterproof.Such as, in Chinese invention patent application CN104612710A, in background skill
Art part discloses a kind of duct pieces of shield tunnel longitudinal seam joint, is common structure of the prior art.Can from Fig. 1 b of this document
See, duct pieces of shield tunnel is reserved with bolt installation hand hole, through penetrating section of jurisdiction between the bolt installation hand hole on adjacent section of jurisdiction
Bolt hole connects, and adjacent section of jurisdiction is connected by built-in connecting bolt.
There is following defect in the duct pieces of shield tunnel of said structure: one, connecting bolt installation hand hole reserved on section of jurisdiction
And bolt hole, segment joint uses built-in connecting bolt to couple section of jurisdiction, although this structure can strengthen tunnel structure globality
Can, but, connecting bolt installation hand hole reserved on section of jurisdiction and bolt hole not only reduce section of jurisdiction mechanical property, also easy shape
Becoming the passage of percolating water, it addition, connecting bolt is built-in at duct piece connector, it is difficult to repair after damaging.Two, in existing design
5cm concrete is had, both as protective layer, again as force part outside steel reinforcement cage within section of jurisdiction.But, at seam areas
Protective layer, bear locally concentrated forces effect when tunnel deformation the most damaged, cracks, crack, falls block etc., forms percolating water
Passage, causes substantial amounts of water leakage defect；And in other position, bury the tunnel structure in underground for a long time by corrosive ion shadow
Ringing relatively big, concrete easily ftractures, and in turn results in reinforcement corrosion, affects tunnel segment structure durability.Three, joint waterproofing, is usually
Use elastic rubber gasket to add hydro-expansive rubber bar at seam crossing, but it is the most aging, durability is relatively low, waterproof effect
Poor, particularly paste with glue and be fixed on surface, section of jurisdiction, easily come off.Chinese invention patent application CN104612710A attempts
The layout of position and water proof rubber by changing bolt solves the problems referred to above, but which results in the lengthening of bolt, bolt
Entirety is had a negative impact by hole layout in tunnel segment structure by force intensity.Four, under high load capacity volume of traffic demand, newly built tunnels
Section presents increasing trend, and the tunnel segment structure thickness adapted therewith is more and more thicker, and sectional space reduces accordingly.China
In a kind of duct pieces of shield tunnel longitudinal seam joint disclosed in application for a patent for invention CN10476341A, by the office to section of jurisdiction connecting portion
Portion thickeies to be increased by force intensity, but it causes the irregular of section of jurisdiction interior shape, for increasing sectional space limited use,
And the problems such as aforementioned section of jurisdiction mechanical property and water resistance can not be solved.
Along with the progress of extensive tunnel construction, large-scale maintenance problem will be faced from now on.Therefore, research is opened
Sending out a kind of, intensity is high, thickness is little, joint damages shield tunnel construction low, that durability is high and has great importance.

Layer 4；It is positioned at the steel nail 5 of the@20cm × 20cm φ 13mm of steel plate both sides；It is positioned at the steel joint 6 of section of jurisdiction lateral margin；Ω shape GINA is only
Water band 7；The junction steel plate 8 of Ω shape.
As it is shown in figure 1, section of jurisdiction main material uses RPC (RPC200), size thickness is 10cm.20mm is thick
Polyurea materials be coated in outside the concrete of section of jurisdiction, it is possible to the direct of isolation concrete and groundwater environment contacts, it is to avoid corrode micro-
The formation of crackle, reduces reinforcement corrosion probability.This polyurea water-proof anticorrosive coat and tunnel segment structure consistent size, but it is not involved in joint
Stress effect, it is to avoid joint damage.
The bar-mat reinforcement of internal both sides, section of jurisdiction design pitch 10cm × 10cm, bar diameter 8mm, strengthens section of jurisdiction self further
Intensity and cracking resistance.
Section of jurisdiction medium design steel plate+steel stud frame, steel plate thickness 13mm, steel nail spacing 20cm × 20cm, it is possible to further
Strengthen the performances such as section of jurisdiction self Anti-pull-press intensity, shear strength, cracking resistance.
Segment design steel joint, joint global design is concave groove type, the upper and lower both sides of joint can bear bigger pressure and
Not easy damaged, groove position can firmly embed GINA waterstop.The excessive position of joint groove uses fillet design, it is to avoid right angle
Damage to waterstop.
As in figure 2 it is shown, seam is connected by inverted Ω shape junction steel plate structure, it is fixed in steel nail or stove bolt
Section of jurisdiction inner surface.
As it is shown on figure 3, Ω shape junction steel plate structure uses steel material, such as Q235B.In the present embodiment, Ω shape connects steel
Plate arc angle is 120 °, and thickness is 60mm.The concrete value of junction steel plate arc angle and thickness needs according to tunnel duct piece
Parameter and tunnel health status select.
As shown in Figure 4, the docking assembly of adjacent section of jurisdiction, GINA waterstop leads to owing to assembly is squeezed in groove internal congestion percolating water
Road, forms first flexible waterproof layer.Ω shape junction steel plate steel nail or stove bolt are fixed on section of jurisdiction inner surface, form second
Steel waterproof layer.Being section of jurisdiction state tension or in compression in that case, pressure is mainly born by steel joint, and pulling force is mainly by Ω shape
Junction steel plate bears.
As it is shown in figure 5, shear action is born in section of jurisdiction, shearing force is mainly born by Ω shape junction steel plate, does not produces between section of jurisdiction
Raw faulting of slab ends effect.
As shown in Figure 6, duct piece connector bears sagging moment effect so that joint joined inside opens.Outside rigidity groove joint
Side forms bending resistance moment with Ω shape rigidity plate.GINA waterstop with angle open deformation fill recess space be still first consolidate
Flexible waterproof layer, Ω shape junction steel plate is the rigidity waterproof layer that second is firm.
As it is shown in fig. 7, duct piece connector bears hogging moment effect so that joint outer side seam opens.In rigidity groove joint
Side forms bending resistance moment with Ω shape junction steel plate.GINA waterstop opens deformation with angle and fills recess space to be still first steady
Solid flexible waterproof layer, Ω shape junction steel plate is the rigidity waterproof layer that second is firm.
