Description
Technical field
The present invention relates to a kind of test unit, especially relate to a kind of duct pieces of shield tunnel circumferential weld anti-permeability performance pilot system.
Background technology
Along with moving forward steadily of China's new round Development of China's Urbanization, urban track traffic has become expansion city physical space, facilitates the important way that the people goes on a journey.And the running tunnel of the system core is handed over as city rail, adopt shield method in a large number.Current shield tunnel lining structure mostly is prefabricated reinforced concrete section of jurisdiction and is spliced by coupling bolt, due to the structural property of segment joint, seam rigidity and bearing capacity are far below the rigidity of section of jurisdiction itself and bearing capacity, it is the stressed weak link in tunnel, especially be in the stratum that this kind of lateral pressure coefficient of muddy soft soil is little, larger seam corner distortion very easily occurs under the impact of periphery engineering activity, seam opens distortion and seam dislocation distortion.
For shield tunnel, percolating water is an outstanding difficult problem for puzzlement structure of the subway safety and normal operation always.Investigation finds, most percolating water all betides segment joint position, and the waterproof sealing of seam generally adopts the elastic sealing gasket be pasted onto near section of jurisdiction extrados to realize.As can be seen here, the anti-permeability performance of tunnel seam is most important for the reliable military service of shield tunnel.The seam of shield tunnel can be divided into longitudinal seam (section of jurisdiction-section of jurisdiction) and hoop seam (Lining Ring-Lining Ring).Therefore, for ensureing the waterproof sealing of shield tunnel in horizontal and vertical two dimensions, need to carry out impervious study mechanism for longitudinal seam and hoop seam respectively.
Make a general survey of domestic and international shield tunnel seam waterproof correlation test device, patent of invention as published in Tongji University---elastic sealing gasket of shield tunnel " yi word pattern " watertightness verifying attachment (CN201010145789), the published utility model patent of Central South University---shield duct piece joint anti-permeability performance test unit (CN104075854A), propose and open rectangular channel separately on upper and lower two pieces of steel cover plates, adopt after elastic sealing gasket being closed into frame-type and be gluingly connected in groove, with bolt, sealing gasket is compressed, pad is utilized to simulate the different joint open of section of jurisdiction, simultaneously at device sidewall mounting limit plate, to simulate the faulting of slab ends situation of section of jurisdiction.Above-mentioned patent is all indoor model tests of small scale, and itself just exists following problems:
1) front duct pieces of shield tunnel is based on prefabricated reinforced concrete section of jurisdiction pattern, adopts steel groove can not reflect the actual contact condition of elastic sealing gasket elastomeric material and concrete groove, thus test findings and the larger discrepancy of engineering physical presence;
2) a large amount of Engineering Projects shows, due to the construction deviation of construction stage duct piece assembling machine, and operation stage soft soil layer the superposition of the multiple factors such as relative settlement, very easily there is the faulting of slab ends amount of 15mm in circumferential weld and circumferential weld, and be limited to the size of cover plate, seam big shearing working condition tests cannot be carried out;
3) adopt bolt presses simulation seam joint open, pad spacing simulation seam faulting of slab ends amount, need manual setting to measure, test accuracy is lower;
4) this patent of invention is positioned the subway tunnel of diameter about the 6m adopting single track elastic sealing gasket waterproof, corresponding cover plate size is less, cannot adopt the waterproof ability of the major diameter cross-river tunnel of more than the diameter 10m of two pass elastic sealing gasket waterproof by scientific evaluation;
5) have ignored the connection of shield tunnel circumferential weld and circumferential weld and the otherness of structure, broadly the impervious condition of two kinds of different seams is lumped together;
6) waterproof ability of actual reinforced concrete segment seam under different open-angle can not be simulated.
7) based on the waterproof test of punching block fixture, cannot the mechanical behavior of simulating reinforced concrete segment joint reality and contact condition.
In addition, by the investigation to domestic and international Patents and document, the test unit that can carry out assay for tunnel circumferential weld waterproof sealing ability is not found.
In sum, in view of duct pieces of shield tunnel seam complexity stress with contact condition; the indoor model test of small scale is difficult to the waterproof sealing mechanism accurately reflecting that it is true and reliable; therefore research and develop duct pieces of shield tunnel circumferential weld anti-permeability performance pilot system, most important for the deep development promoting shield tunnel waterproof technique field.
