The flexible segment is characterized in that a steel-cast left box-type segment part (1a) and a steel-case left box-type pipe segment (1b) are arranged in bilateral symmetry, a right side of the left box-type segment part (1a) and a left side of the right box-type segment part (1b) are connected to the outer radial side through two inverted-omega-shaped steel-edge waterstop belts (2), an inner radial side of the right side of the left box-type segment part (1a) is hinged with a left spherical universal hinge (3a), an inner radial side of the left side of the right box-type segment part (1b) is hinged with a right spherical universal hinge (3b), and a connecting cavity (3c) of a connecting rod of the right spherical universal hinge (3b) is sleeved on a connecting rod of the left spherical universal hinge (3a). The flexible segment can remarkably improve flexibility of segment lining and improve safety and durability of the shield tunnel.
Description
Technical field
The present invention relates to a kind of shield tunnel and use flexible section of jurisdiction.
Background technology
At present, shield method with its safety, efficient, automaticity is high, advantages such as peripheral disturbance is little have greatly been promoted the development of China's shield tunnel.Shield tunnel is widely used in China's city underground, railway, highway and municipal submerged tunnel at present.
Shield tunnel liner generally adopts the assembling pipe-plate lining structure, namely utilizes the hoop bolt to connect into the lining cutting ring by the prefabricated pipe section with the several piece arc, and the recycling longitudinal bolt extends to form the pipe-plate lining structure with vertical connection of some lining cutting rings.Under load often, the mechanical properties such as flexibility of pipe-plate lining structure all can satisfy safety and the life requirement of be correlated with subway, railway and highway standard.But under following situation, its flexibility that vertically connects then can not meet the demands, and causes the tunnel to destroy:
One, the big position of tunnel lining stiffness differences: because the functional requirement of shield tunnel, pipe-plate lining needs with other forms of, is connected as vertical shaft (shield launching well, shield machine are to sending out well), ventilating shaft, contact transverse passage-way, pump house etc.The connecting portion of pipe-plate lining and these structures has significantly changed the rigidity of tunnel structure self, causes that easily stress is concentrated and the lining cutting cracking, causes the tunnel to destroy.
Two, the big position of tunnel lining penetrating ground difference: when the vertical penetrating ground characteristic of shield tunnel marked change place (hard-soft heterogeneous ground, country rock rank gap is big or have big stratum, joint), when passing through unfavorable zone such as high-intensity earthquake area.Bigger heterotaxis can take place in the stratum of these positions under long-term vibrating load or accidental seismic load, the uneven sedimentation in serious stratum takes place, utilize longitudinal bolt to realize the pipe-plate lining that vertically connects, its whole flexibility then is difficult to adapt to the requirement of this stratum large deformation (or big displacement), can cause that stress is concentrated and the lining cutting cracking, cause the tunnel to destroy.
Summary of the invention
The purpose of this invention is to provide a kind of shield tunnel and use flexible section of jurisdiction, this flexibility section of jurisdiction can significantly improve the flexibility of pipe-plate lining, improves safety and the durability of shield tunnel.
The present invention realizes that the technical scheme that its goal of the invention adopts is, a kind of shield tunnel is used flexible section of jurisdiction, it is characterized in that: the right box section of jurisdiction parts bilateral symmetry of the left box section of jurisdiction parts of steel casting and steel casting, the left side of the right side of left box section of jurisdiction parts and right box section of jurisdiction parts is connected by the twice shaped steel of falling Ω limit waterstop at radial outside; The hinged right spherical universal hinge of radially inner side on the hinged left spherical universal hinge of the radially inner side on the parts right side, box section of jurisdiction, a left side, the parts left side, right box section of jurisdiction; The connection chamber of the connecting rod of right spherical universal hinge is linked on the connecting rod of left spherical universal hinge.
Using method of the present invention is:
At the reinforced concrete segment of the general position assembly unit routine of shield tunnel, the reinforced concrete segment that is about to the several piece arc utilizes the hoop bolt to connect into the lining cutting ring, and the recycling longitudinal bolt vertically connects some lining cutting rings and extends to form the pipe-plate lining structure; And in tunnel lining stiffness differences bigger position and the bigger position of tunnel lining penetrating ground difference, as required, adopt the reinforced concrete segment of flexible section of jurisdiction of the present invention routine, namely in the pipe-plate lining section, be substituted into one or more flexible pipe loops.
Compared with prior art, the invention has the beneficial effects as follows:
Flexible section of jurisdiction of the present invention, by the left box section of jurisdiction parts of symmetry and right box section of jurisdiction parts and left and right spherical universal hinge hinged, and left and right spherical universal hinge connects in piston type sleeve mode; The safe deformation range of the steel limit waterstop of the type of falling Ω is also bigger simultaneously; Can rotate in any direction, move thereby make between the parts of left and right box section of jurisdiction.It is installed in the bigger position of tunnel lining stiffness differences and the bigger position of tunnel lining penetrating ground difference, has namely formed flexible ring in this section lining cutting.Because the big displacements of degree of freedom direction arbitrarily such as flexible ring can stretch, compresses, shearing, rotations, thereby significantly improve the comprehensive deformation ability of lining cutting.Finally, under the optimization improvement of an amount of flexible ring of particular design position, improved safety and the durability of shield tunnel:
1, significantly reduced the rigidity of binding site, effectively avoided stress to concentrate structure crack and the destruction that causes, made the concentrated stress of the big position of tunnel lining stiffness differences obtain discharging.
2, the subsidiary stress that acts on pipe-plate lining that adopts extraneous factors such as adapting to distortion earthquake but not the flexible section of jurisdiction of resistance to deformation can effectively be subdued, vibration, stratum difference to produce, make when unfavorable positions such as shield driven tunnel crossing high intensity Zone, weak intercalated layer and the uneven alternating layers of soft or hard district, adapt to each to the ability raising of large deformation or displacement greatly (particularly differential settlement, Compression and Expansion that quantity is bigger).
Experiment shows that permission stretching, the decrement of single flexible ring of the present invention are ± 10cm-± 15cm to allow shearing displacement: 5-10cm, permission crooked (rotation) amount: 10 °-15 °.
The radial outside on the above-mentioned parts right side, left box section of jurisdiction protrudes the left boss that forms one " day " font to the right, the radial outside on the parts left side, described right box section of jurisdiction protrudes the right boss that forms one " day " font left, and left end and the right-hand member of the described twice shaped steel of falling Ω limit waterstop are connected on left boss and the right boss.
Like this, can reduce the width of the shaped steel of falling Ω limit waterstop, improve the application life of waterstop.
The outermost radial outside of above-mentioned left boss is protruded the left overhanging backplate of formation " " font to the right; The outermost radial outside of right boss is protruded the right overhanging backplate of formation " " font left.
Left and right overhanging backplate can be protected the shaped steel of falling Ω limit waterstop, makes it not be subjected to extruding and the bump of outside big country rock fragment.
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
