Abstract
The utility model relates to a shock isolation waterproof union, which is characterized in that two rows of slide bolt bands are arranged between the connecting end surface of the concrete pipe section, and each row of slide bolt band is composed of slide bolts which have equal space and identical structure; the middle part of each slide screw is provided with a hollow double conical rubber cylinder and a double conical helical spring. Two baypren rings and two folding rubber soft boards which are provided with omega-shaped section are arranged in parallel along the pipe section connecting end surface, and an outer package fibre board sealing is arranged along the outer edge of the pipe section connecting part. The utility model has the advantages of capability of adapting structure displacement, impact and load resistance, earthquake energy elimination and no leakage and crack, which is suitable for shock isolation waterproof joint of the underwater tunnel.
Description
The utility model belongs to the connection of concrete member, particularly is immersed in the shock insulation water joint that tunnel pipeline section under water connects.
At present, when the pipeline section of submerged tunnel engineering connects, what adopt is " pipeline section rigid joint ", promptly between the tunnel pipeline section, adopt drawing jack and waterstop as joint, the drawing jack is close with two pipeline section drawings of adjacent segments, slit about 10 centimetres is arranged therebetween, lucky that [Gina] waterstop is set in the slit.Lucky that waterstop is a kind of rubber tape of Rockwell hardness 50～60 degree, and the raised rubber band of hardness low slightly [35 spend] is adopted at the position that it contacts with the pipeline section end face, and whole formation is rigidly connected, and uses in majority submerged tunnel engineering both domestic and external.The shortcoming of rigid joint is can't adapt to the displacement of pipeline section, so pipeline section is unsuitable long; When being used for deepwater field, leakage performance is relatively poor; Use at high intensity Zone, easily be torn, break, be difficult to adapt to region, delta, area, straits, have the region that surge strongly spring tide and earthquake take place to construct the needs of submerged tunnel engineering at great rivers.
The purpose of this utility model is, design a kind of joint of hard and soft combination, make it possess energy-dissipating and shock-absorbing, adapt to tunnel pipeline section displacement and water-proof function requirement, the connection part that is used for submerged tunnel bridge tube section, can guarantee that structure bears the water pressure of various dynamic loads, ensure the non-leakage water of tunnel pipeline section, can in the sea bed geosyncline, whole segmentation wriggle, improve the performance of combating a natural disaster of tunnel pipeline section.
The hard and soft union of shock insulation waterproof of the present utility model, form by drawing part and sealing part, it is characterized in that, the drawing part is provided with two row's slide bolt bands for connecting at pipeline section between the end face, every row's slide bolt band is equated by spacing, constructing identical slide bolt forms, the concrete structure of each slide bolt is, by the sliding plate of mounting hole in the setting of pipeline section end face, be installed with the screw rod of major diameter stainless steel slide bolt, be provided with spring washer and nut at the screw rod two ends, be provided with hollow biconial rubber tube at the screw rod middle part, be provided with the biconial helical spring in the hollow biconial rubber tube; Sealing part is for connecting end face be arranged in parallel the chloroprene rubber ring and the collapsible rubbery flexible sheet of twice of twice Ω type section along pipeline section, along the outer rim of pipeline section connection part the outer wrapping fiber disc seal is set.
Using method of the present utility model is, in the tunnel bridge pipeline section termination of sinking under water Ω type chloroprene rubber ring is set, and slide bolt is set in mounting hole; The tunnel bridge pipeline section push-and-pull of sinking newly is in place, with slide bolt two pipeline section drawings are connected; Inside and outside both sides at connection part are provided with collapsible rubbery flexible sheet, at connection part arranged outside outsourcing high-intensity fiber disc seal.
The hard and soft union of shock insulation waterproof of the present utility model, its slide bolt can be under external force, and generation level, vertically to displacement to eliminate seismic energy, reduces the effect of impact load; The Ω type cavity of chloroprene rubber ring, influence that can the commensurate structure displacement becomes the waterstop that seepage does not take place; Collapsible rubbery flexible sheet can stretch 300 millimeters and do not rupture, and does not destroy water-proof performance.Arrange the hard and soft union of shock insulation waterproof that the slide bolt bands constitute by waterproof defence line, five roads and two, be applicable to the deep water waters, if it is sea water advanced more than 80 meters, can in the space between the chloroprene rubber ring of twice Ω type section, pour into the high-effective water-proof material or the silicone rubber astragal is set, to improve anti-water effect; The hard and soft union of shock insulation waterproof is specially adapted in the big Underwater Engineering of submerged tunnel bridge class elastic displacement, when the tunnel bridge axis by the fault belt district or when crossing over narrow trench, pipeline section every segment length in tunnel can extend to 300～500 meters, can make submerged tunnel bridge construction body have the superpower performance of taking precautions against natural calamities; Hydrodynamic pressure, impact the burst load, coupling such as move produce and do the time spent, pipeline section termination, tunnel should be provided with the use that matches with the hard and soft union of shock insulation waterproof of thick seat cushion, the assurance joint is not torn, breaks.
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the organigram of the hard and soft union of shock insulation waterproof
As seen from the figure, the hard and soft union of shock insulation waterproof of the present utility model, form by drawing part and sealing part, it is characterized in that, the drawing part is provided with two row's slide bolt bands for connecting at pipeline section between the end face, every row's slide bolt band is equated by spacing, constructing identical slide bolt 1 forms, the concrete structure of each slide bolt is, by the sliding plate 2 of mounting hole in the setting of pipeline section end face, be installed with the screw rod of major diameter stainless steel slide bolt, be provided with spring washer 3 and nut 4 at the screw rod two ends, be provided with hollow biconial rubber tube 5, be provided with biconial helical spring 6 in the hollow biconial rubber tube at the screw rod middle part; Sealing part is for connecting end face be arranged in parallel the chloroprene rubber ring 7 and the collapsible rubbery flexible sheet 8 of twice of twice Ω type section along pipeline section, along the outer rim of pipeline section connection part outer wrapping fiber plate 9 is set and seals.
