Description
Technical field
The utility model belongs to the field of measuring techniques of measuring length thickness and similar linear dimension, be specifically related to by measuring each point coordinate be used for gauge length, width, thickness to use measurer or the metering outfit of mechanical means for its feature.
Background technology
The tunnel is built in underground rock soil medium, belong to half concealed work, runed the influence of factors such as the time limit, weather conditions, design, construction, make operation tunnel disease quantity more and more, be in particular in: liner structure distortion is invaded limit, crack, faulting of slab ends, falls piece, is caved in, percolating water, substrate are risen soil, sinking, pucking etc., wherein the crack is a kind of very general disease, and is the direct or indirect reason of other disease.According to the document announcement of the relevant tunnel slot of Japan, 1979, Japan carried out investigation statistics to 3807 tunnels, percolating water have 2135, account for 56%, the length of leaking reaches 70%, wherein the crack is the main channel of percolating water.1986, Japan was investigated the coldest Hokkaido local highway tunnel defect, had 141 the crack to occur, leak in 302 vcehicular tunnels in Hokkaido, icingly caused the crack to be subjected to cyclic load to carry effect in the hole in, and the crack is constantly developed.April nineteen ninety, existing 6705 vcehicular tunnels of Japan, length overall 1970km, investigation finds that the tunnel quantity that disease takes place accounts for 23.9% of tunnel sum, in the tunnel that worsens, the situation that the lining cutting cracking occurs is maximum.
For vcehicular tunnel, the investigation of Hokkaido, Japan institution of civil engineers vcehicular tunnel branch shows, by in Dec, 1986, vcehicular tunnel during use in Hokkaido has 302, comprising national highway, urban road and car lane, investigation finds that lining cutting has appearred in 141 tunnels and the road surface is damaged, account for tunnel sum 50% nearly, the main disease in tunnel shows as: lining cutting cracking, along crack place's percolating water and freezed in winter.Discover that the influence of tunnel cracking, seepage and icing constructed age and freezing index is bigger, and is subjected to the influence of geologic condition less; The tunnel-liner distortion that is caused by bias voltage seldom only accounts for 8% of disease tunnel, and distortion is distinct issues.
According to China railways tunneling technique statistic in 1997, there was seat surplus the operation tunnel 5000 in the whole nation, amounts to 2500km, wherein serious crack, leaked, and influenced reach 1502 of tunnel operation, accounted for about 30% of tunnel sum.Works Bureau of China Ministry of Railways in 1972 and capital construction general bureau investigate and analyse dissimilar (holocentric circular arch, three-centred arch, straight flange wall and bent abutment wall, single line and two-wire section) tunnel concrete lining cutting causes of cracks that 30～seventies of the whole nation builds under different geology (hard, soft rock, loess) condition, investigate 94 in tunnel altogether, length overall 80.7km, 93.2% tunnel-liner cracking is arranged approximately, and fracture length accounts for tunnel length overall 19.2%.Nineteen ninety-five and 1997, Ministry of Railways's works department shows that to China railways tunneling technique statistic its disease tunnel accounts for 50%, 30% of tunnel sum respectively, and main disease is the tunnel cracking.Nineteen ninety-five, 4855 of the total operation tunnels of China railways, total length 2261.56km, the main disease of existence is to invade limit, crack and leak.According to the detection of works department autumn nineteen ninety-five, not enough 2546 of invading track clearance of headroom are seriously leaked 1428, and lining cutting is seriously ftractureed 677,212 of inverted arch distortion.Crack disease has in various degree all appearred in the tunnel in numerous constructions and the operation, and this has caused extensive attention, and the monitoring and the analysis and Control in crack have been mentioned agenda.
The Tunnel Lining Cracks detection method has multiple, and common measures with vernier caliper such as brush paint method, plaster strip method, both sides, crack ailing, and the joint meter method for measurement etc.The paint method is similar to the plaster strip method, is comparatively rough method for measurement, whether can judge the crack in sustainable development, and ailing cooperates the vernier caliper method for measurement to belong to the one dimension measurement, can only judge the development of fracture width, and measured value is accurate relatively.In addition, also available special joint meter measures.Domestic had joint meter and a three-dimensional crack gauge, though the joint meter measured value relatively accurately and is easy to install, but generally can only carry out the one dimension joint measurement, the three-dimensional crack gauge then is mainly used in the opening of monitoring dam body, side slope, engineering rock mass or mountain cracks, the closed or distortion of the changing of the relative positions up and down, and, when this instrument is used for the measurement of inner concrete crack, tunnel, install quite inconvenient.
