Description
Technical field
The present invention relates to the method for real-time monitoring of rubber fastening band, be specifically related to a kind of method for real-time monitoring and type inflatable rubber fastening band thereof towards immersed tube tunnel rubber fastening band.
Background technology
Concrete is pressed the common You San of joint seal structural shape road water-stopping system at present: seam bottom waterstop, seam middle part sealing and seam table portion sealing.Generally, for the keypoint part of key project, common three road water-stopping systems use simultaneously, but a lot of engineering only arranges seam middle part water-stopping system conventionally one; In work progress, the deformation joint complex structure of structure, arranges waterstop difficulty of construction therein larger, in work progress, also, easily by mounted waterstop displacement and distortion, is difficult to ensure the installation quality of waterstop simultaneously.
In the daily operation in tunnel, daily monitoring and maintenance are manually carried out in basic dependence, detection and replacing for rubber fastening band all have very large difficulty, generally can only just can remedy nosing into after the situation of leaking, so not only inefficiency, and occur illustrating while leaking situation that the operation situation in tunnel is very poor, have huge potential safety hazard.If rubber fastening band is monitored in real time, once occur extremely in time the rubber fastening band breaking down being safeguarded or being changed, the safe operation that ensures tunnel is of great immediate significance.At present, what the first of immersed tube tunnel hermetic seal system protection both at home and abroad adopted substantially is GINA rubber fastening band, uphold although this rubber fastening band can adapt to differential settlement and the large displacement of pipeline section the distortion causing, can play better stagnant water effect, its shortcoming is:
1, required precision is high, in actual mechanical process, cannot quantitatively control, in installation process, because the tube coupling sinking required precision to immersed tube tunnel is very high, but can not connect by the contraposition that regulates the size of GINA rubber fastening band compression height realize immersed tube tube coupling, tend to cause in installation process, occur crooked etc.
2, process function is more single, and decrement size that cannot Quantitative Monitoring GINA rubber fastening band cannot shift to an earlier date the sealing operating condition of anticipation GINA rubber fastening band,
3, due to the existence of rubber slack, easily cause water stopping function lost efficacy, and conventional structure do not have restorative, sealing lost efficacy after cannot complete reparation.
4, isostructural GINA rubber fastening band cost is higher, and material expense is large, must rely on a large amount of rubber to fill GINA rubber fastening band main part.
In sum, the conventional GINA rubber fastening band of a large amount of employing at present, mainly contains tip, body and bottom three parts and forms, by the narrow structure division in compression tip, reach the quick sealing of immersed tube tunnel, continue to be compressed to body, can better maintain long sealing requirement, but the limitation of this structure is very large, function ratio is more single, and installation accuracy is had relatively high expectations, in service cannot quantitatively monitoring, long-term meeting in service is because the appearance of rubber slack causes stagnant water effect to be lost.
Find through retrieval, name is called the utility model patent of " a kind of bar-shape hermetic seal air bag " and has recorded a kind of bar-shape hermetic seal air bag, it is characterized in that: described bar-shape hermetic seal air bag is provided with Valve for aerocyst 1, the cross section of air bag is pancake, respectively there is a transitional inclined-plane 2 for air bag overlap joint at two ends, make the sealing of air bag junction reliable, can effectively solve the problem sealing between object, especially solve a difficult problem for the waterstop sealing between casing stake hole and pile body in water, bar-shape hermetic seal air bag is not only applicable to the sealing of the circumferential weld of various forms, can also be applicable to vertical masonry joint, the sealing of plane.The utility model patent that name is called " hollow is inflatable, water-bound seam waterproof rubber strip " discloses that a kind of hollow is inflatable, water-bound seam waterproof rubber strip.It belongs to subterranean tunnel architectural waterproof material, applicable to current common tunnel construction and underground construction.Its structure is oval, and section structure is divided into sealing surface, fire hose and union, and outside flat seal face, inner side fire hose are integrated, union is planted in flank through ectonexine; The section structure of its oval rubber fastening band of the utility model makes sealing surface in the time of work realize controllability, produce the vertical changing of the relative positions of 500mm and the horizontal changing of the relative positions of 50mm between ground fissure place upper lower burrs agent structure time, the agent structure of water proof rubber is not destroyed, obstructing surface is connected in two flanks with ellipse, multiple tracks water-proof wire is set in sealing surface main body, its main body bends in the reserved seam of tunnel main body with annular, and water-proof wire can be set to one or multi-channel.Above-mentioned two kinds of structures can realize the water stopping function at simple bar shaped seam and plane suture place, but do not there is fastness function, can produce floating, require very high to installed surface, decrement is smaller, is not suitable for deep water field and the immersed tube tunnel hermetic seal function with flexible joint field.
Summary of the invention
The object of the invention is to for above-mentioned technical problem provide a kind of by gather the real time data of rubber fastening band and empirical data compare to realize real-time monitoring to rubber fastening band towards immersed tube tunnel rubber fastening band method for real-time monitoring.The present invention also provides a kind of energy quantitatively regulating and controlling and monitoring, can realize the type inflatable rubber fastening band of tunnel pipe connector place water stopping function safe and convenient, not only can meet decrement and the shearing displacement of the large displacement in tunnel pipe connector place, thus and can be by regulating the expansion of center sleeve and compressive state quantitatively regulate the decrement of rubber fastening band.
