Abstract
A lining structure of shield tunnel adapting nonuniform subsidence or dislocation of mass value stratum sets lining ring section with big deformation in said structure to increase longitudinal flexibility of said structure and to raise structure adaptability to nonuniform subsidence and dislocation while cross section of shield tunnel is expanded.
Description
Technical field
The present invention relates to tunnel-like, relate to a kind of shield tunnel lining structure of the adaptable for large value stratum ununiform settling or changing of the relative positions concretely.
Background technology
Ground fissure be face of land rock-soil layer under natural cause and human factor effect, produce cracking and form the phenomenon in certain-length and width crack on ground.Ground fissure is the result of multifactor stack, and in the ground fissure activity system, its origin cause of formation act as the master with natural geology, and human factor is auxilliary.The activity of ground fissure has three-dimensional deformation characteristics, shows as vertical sedimentation, horizontal stretch-draw and twisting.
Because the activity of ground fissure is a dynamic change procedure, the origin cause of formation, mechanism and type are all very complicated, and has tangible segmented activity feature according to moving towards difference, the face of land that has has obviously and appears, the tool that has is lain concealed property, to build, the destruction form of structure also has nothing in common with each other, so the method for preventing and treating of engineering also should be at the different active situation and the space exhibition step characteristic of ground fissure, segmentation is considered.
At ground fissure active situation and space exhibition step characteristic, need relevant specialities such as circuit, structure, track and waterproof to take all factors into consideration.At first structure design will adapt to its different deformation requirements, the displacement of its generation is controlled in the default position and structure, and this body structure of tunnel is not damaged.In this scope, reserve enough deformation spaces simultaneously,, and handle joint waterproofing well so that adjust track circuit.
In the construction of tunnel of prior art, the ground fissure for a large amount of value stratum differential settlements or the changing of the relative positions cause for example in the above changing of the relative positions amount of 10mm, does not also have efficient ways at present.
Summary of the invention
The objective of the invention is according to above-mentioned the deficiencies in the prior art part, a kind of shield tunnel lining structure of the adaptable for large value stratum ununiform settling or changing of the relative positions is provided, this structure is when enlarging the shield tunnel section, large deformation lining cutting ring section is set in structure, increased the longitudinal flexible of structure, improved the compliance of structure the differential settlement and the changing of the relative positions.
The object of the invention realizes being finished by following technical scheme:
A kind of shield tunnel lining structure of the adaptable for large value stratum ununiform settling or changing of the relative positions, connect and compose by some lining cutting ring sections, the internal diameter overgauge section shield tunnel liner ring section internal diameter that it is characterized in that described lining cutting ring section, if wherein the difference of the two is a Δ, then described Δ value, satisfying under the safety factor of national Specification, corresponding with the discreet value of this structure location stratum differential settlement or changing of the relative positions maximum perpendicular displacement in design period.
Having one in described some lining cutting ring sections at least is large deformation lining cutting ring section, and it is assembled that this lining cutting ring segment structure adopts two lining papers to build ring, and lining cutting ring assembly unit face is provided with the location and installation hole.
What adopted the section of jurisdiction of described lining cutting ring is steel material.
Place, described location and installation hole can adopt bolt to connect location and installation.
Be reserved with Grouting Pipe on the section of jurisdiction of described lining cutting ring.
Advantage of the present invention is, simple in structure, reliable in quality can adapt to the stratum settlement and the changing of the relative positions of higher value, avoids the damage of reinforced concrete segment in the tunnel, and every ring large deformation ring design can adapt to changing of the relative positions amount and the circumferential weld amount of opening of 10-100mm.
Summary of drawings
Accompanying drawing 1 is Facad structure schematic diagram of the present invention;
Accompanying drawing 2 is side structure schematic diagram of the present invention;
Accompanying drawing 3 is the local enlarged diagram of accompanying drawing 2;
Concrete technical scheme
Feature of the present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
As Figure 1-3, label 1-8 represents respectively: steel pipe sheet 1, steel pipe sheet 2, two ring steel pipe sheet stitching positions 3, Ω type waterstop 4, location and installation hole 5, nut 6, bolt 7, packing ring 8.
Embodiment:
Present embodiment is connected and composed by some lining cutting ring sections, wherein the internal diameter overgauge section shield tunnel liner ring section internal diameter of lining cutting ring section.Vertical displacement amount in ground fissure position is bigger, the cross dimensions of standard section design is the requirement of crack place's malformation contentedly, therefore influence the shield tunnel that band scope domestic demand designs big section in ground fissure, take into full account the deflection that it causes because of the ground fissure development during metro operation.During design, should be according to the discreet value of ground fissure maximum perpendicular displacement in design period in the scope of design, consider that certain safety factor determines the design load Δ.Be made as A as standard section shield tunnel liner internal diameter, then enlarging section shield tunnel liner internal diameter is the A+ Δ.By circuit supertronic, track adjustment, operation monitoring and integrated control means such as the slip casting processing combines, its adaptable maximum settlement is greater than the A+ Δ.
According to subsidence curve, keep at a certain distance away in some lining cutting ring sections and arrange a large deformation ring, the large deformation ring of present embodiment is assembled by steel pipe sheet 1, steel pipe sheet 2, and the assembly unit face of two rings is provided with location and installation hole 5.
Adopt bolt 7 to connect the location at 5 places, location and installation hole between constructing tunnel stage steel pipe sheet 1, steel pipe sheet 2, after the propelling of whole piece tunnel finished and be stable, loose nut 6 was installed Ω rubber fastening band 4, and this joint form can adapt to the lining cutting ring and open more greatly and the changing of the relative positions.In the structure operational phase, can reach by demounting bolt 7 and allow the purpose of malformation, with the stratum settlement and the changing of the relative positions that adapts to higher value.
Butterfly spring can be filled up in the position of the packing ring 8 on bolt 7, to discharge the longitudinal bolt stress in tunnel, avoids the damage of reinforced concrete segment.
During specific design, every ring design can adapt to changing of the relative positions amount and the circumferential weld amount of opening of 10-100mm.
Steel pipe sheet 1, steel pipe sheet 2 can be reserved Grouting Pipe, can adopt grouting and reinforcing to handle to the empty stratum that forms because of below, ground fissure motion tunnel at any time.
For the selection of steel pipe sheet 1, steel pipe sheet 2 diameters, the active level that needs to consider ground fissure or stratum sudden change sedimentation on the basis of existing structure design size is determined the affluence amount of size.
