Description
Technical field
It the utility model is related to shield tunnel design and construction technical field, and in particular to a kind of shield tunnel shock-resistant and energy-dissipating subtracts
Shake node structure.
Background technology
With China's economy, the fast development of society, Large Underwater Tunnel Engineering has been enter into fast-developing phase, shield method tunnel
Road is widely used because of the features such as its is safe, quick, scientific and technological.Generally, shield tunnel chip architecture is not taken
Special earthquake resistant construction.But the antidetonation of shield tunnel chip architecture, glissando need under complicated geological, highlight lines earthquake region severe earthquake action
Design.Do not take the special main construction procedure of earthquake resistant construction duct pieces of shield tunnel as follows：
1st, section of jurisdiction makes；
2nd, section of jurisdiction is transported；
3rd, interior pipe sheet assembling；
The 4th, section of jurisdiction endless loop is installed to, longitudinally connected bolt；
5th, section of jurisdiction back-grouting.
Utility model content
The defects of the purpose of this utility model is to be directed to prior art and deficiency, there is provided one kind adapts to large deformation, can answered
Position reduces section of jurisdiction circumferential weld spacing, consumes the shield tunnel shock-resistant and energy-dissipating damping node structure of inputting seismic energy.
To achieve the above object, the technical solution adopted in the utility model is：It includes the adjacent shield duct piece of two rings, steel
Plate, nut, marmem plate, bolt, segment joint；The adjacent shield duct piece intrados of two described rings be provided with steel plate and
Nut, marmem plate, marmem plate difference are provided with the inside of the segment joint of the adjacent shield duct piece of two rings
Spun by bolt through steel plate with nut.
Preferably, described steel plate and nut is embedded in the adjacent shield duct piece of two rings.
Preferably, it is provided with bolt hole on described marmem plate.
Operation principle of the present utility model is：Using two adjacent endless tube pieces of existing shield tunnel, by section of jurisdiction system
Intrados pre-embedded steel slab and nut when making, after the shaping of pipe sheet assembling tunnel, by bolt with can restore to the original state performance, Gao Yan
Property, the marmem plate that can consume inputting seismic energy is fixed on the inside of section of jurisdiction.During generation earthquake, under severe earthquake action,
Stratum relative settlement is adapted to, reduce section of jurisdiction circumferential weld spacing and ensures tunnel structure safety.
After said structure, had the beneficial effect that caused by the utility model：
1st, the Structure adaptation large deformation, can reset reduce section of jurisdiction circumferential weld spacing, consumption inputting seismic energy；
2nd, marmem plate can be repaired, replaced, easy to maintenance；
3rd, produce using common segment die, without making special segment die again, make simple；
4th, construction technology is simple, and construction investment is few.

Cambered surface is provided with steel plate 2 and nut 3, and the inner side of the segment joint 6 of the adjacent shield duct piece 1 of two rings is provided with marmem plate
4, marmem plate 4 is spun by bolt 5 through steel plate 2 with nut 3 respectively.
Preferably, described steel plate 2 and nut 3 are embedded in the adjacent shield duct piece 1 of two rings.
Preferably, it is provided with bolt hole on described marmem plate 4.
The operation principle of present embodiment is：Using two adjacent endless tube pieces of existing shield tunnel, by pipe
Intrados pre-embedded steel slab and nut when piece makes, after the shaping of pipe sheet assembling tunnel, by bolt have the performance that can restore to the original state,
High ductility, the marmem plate that can consume inputting seismic energy are fixed on the inside of section of jurisdiction.During generation earthquake, severe earthquake action
Under, stratum relative settlement is adapted to, reduce section of jurisdiction circumferential weld spacing and ensures tunnel structure safety.
When present embodiment operates：
1st, when section of jurisdiction makes, in the section of jurisdiction intrados pre-embedded steel slab and nut apart from section of jurisdiction circumferential weld certain distance；
2nd, after the shaping of pipe sheet assembling tunnel, pre-buried steel plate and nut can form one on the intrados of tunnel duct piece
Circle；
3rd, with bolt the marmem plate with bolt hole made, installed in section of jurisdiction intrados pre-embedded steel slab
On；
4th, it is closely connected between mounted marmem plate and section of jurisdiction intrados.
After said structure, had the beneficial effect that caused by present embodiment：
1st, the Structure adaptation large deformation, can reset reduce section of jurisdiction circumferential weld spacing, consumption inputting seismic energy；
2nd, marmem plate can be repaired, replaced, easy to maintenance；
3rd, produce using common segment die, without making special segment die again, make simple；
4th, construction technology is simple, and construction investment is few.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.This
The technical staff of industry is retouched in above-described embodiment and specification it should be appreciated that the utility model is not restricted to the described embodiments
That states simply illustrates principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model
