Description
Technical field
The present invention relates to Tunnel Engineering technical field, more particularly to a kind of segment joint sealing gasket water resistance test device
And experimental method.
Background technology
Shield method is widely adopted in China's tunnel construction at present, and shield tunnel liner uses prefabricated reinforced concrete more
Pipe-plate lining is spliced, and the section of jurisdiction of splicing needs to take tight waterproof measure in seam crossing.Under the conditions of prior art, section of jurisdiction
Seam waterproof is mainly realized by the way of sealing gasket sealing.Groove, groove typically are set at the fitting position of segment joint
Middle installation sealing gasket, during pipe sheet assembling, the sealing gasket between section of jurisdiction is compressed using jacking power, then consolidated by fastener
Surely the both sides section of jurisdiction being bonded, so that sealing gasket keeps densification state, to have the function that waterproof, effect.
At present, sealing gasket design there is no general theoretical direction, frequently with experience and the design meanses of experiment.Design process
In by substantial amounts of waterproof test, reach the test objective of research joint seal pad water resistance.But because section of jurisdiction is spliced
Mode is different, and segment joint type is also varied, and section of jurisdiction connecting method includes straight joint splicing and spliced with the fissure of displacement, and the fissure of displacement splices such as
Shown in Fig. 1, tunnel is spliced by multiple tube couplings, and each tube coupling is spliced by the section of jurisdiction 14 of multiple arc sections, section of jurisdiction 14 with
" one " word seam 12A is formed between section of jurisdiction 14, forms circumferential weld 12D between two neighboring tube coupling, " one " between two neighboring tube coupling
Word seam 12A be staggeredly arranged so that " one " word seam 12A and circumferential weld 12D between formed " T " word seam 12B, straight joint splicing as shown in Fig. 2
Tunnel is spliced by multiple tube couplings, and each tube coupling is equally spliced by the section of jurisdiction 14 of multiple arc sections, section of jurisdiction 14 and section of jurisdiction
" one " word seam 12A is formed between 14, forms circumferential weld 12D between two neighboring tube coupling, " one " word seam between two neighboring tube coupling
12A is alignd, and " ten " word seam 12C is formed with circumferential weld 12D." one " word seam is most common seam, and two sections of jurisdiction are right in any way
When connecing, " one " word seam is respectively formed, and " ten " word seam is located at longitudinal joint and circumferential weld（Transverse joint）Intersection, and longitudinal joint and circumferential weld（Transverse joint）Hand over
Follow-up renew of converging is stretched, so as to form " ten " word seam；" T " word seam also is located at longitudinal joint and circumferential weld（Transverse joint）Intersection, but two connect
After seam crosses, only a seam continues to extend, so as to form " T " word seam.
For water resistance of the different seams under the conditions of certain joint open, faulting of slab ends amount of analyzing and researching, have devised perhaps
More experimental rigs, such as elastic sealing gasket of shield tunnel " yi word pattern " watertightness disclosed in application number " 201010145789.1 " are examined
Experiment device, its applying date are on April 14th, 2010, and data of publication of application is on December 29th, 2010, can effectively simulate section of jurisdiction not
With the water proof case of elastic sealing gasket in the case of joint open and faulting of slab ends amount.But this kind of device can only simulate a kind of seam type,
Or " one " word seam can only be simulated, or " T " word seam can only be simulated, pilot project is single.
In Practical Project construction, generally there is the seam of two or more type in section of jurisdiction splicing simultaneously, the two, two
Interactional situation generally be present in the seam of type, for example, when " one " word seam and " T " word seam simultaneously be present, " T " word seam
In the case of different joint opens, the faulting of slab ends amount of " one " word seam is also different；When " T " word seam and " ten " word seam simultaneously be present, " T "
Word is sewn in the case of different faulting of slab ends amounts, and the faulting of slab ends amount of " ten " word seam is also different, and existing device can not take into account a variety of seams
Interactional situation, obtained water resistance data and actual condition have differences, and can not be provided for Practical Project valuable
Reference.
In addition, existing watertightness is examined（Experiment）In device, install sealing gasket groove structure type also with live work
Condition is not inconsistent, and causes to be tested at the same conditions, and obtained test data is lost biased, and reference value is limited, leads
In the presence of certain security-hidden trouble during cause practice of construction.
