Description
Technical field
The utility model belongs to the underground works sedimentation and deformation and observes field, particularly a kind of subway sectional tunnel settlement observer.
Background technology
Subway engineering is the important infrastructure that improves the large-and-medium size cities traffic.China's subway construction was later than the world 100 years, and what put into effect has cities such as Beijing, Tianjin, Shanghai, Guangzhou, Nanjing, Shenzhen.According to statistics, granted construction subway engineering of 30 cities was nearly arranged in recent years.Under the background of urban transportation growing tension, citizen are with great expectations to subway.Thirsting for building up of subway can offer convenience to trip, also wishes simultaneously the subway line maintenance safety of having runed, comfortable kilter.
But subway engineering is built in underground Rock And Soil medium more, and engineering geological condition and complicated hydrogeological conditions have a lot of uncertainties, along with increasing or other specific factor of the operation time limit, the excessive and secondary disease of sedimentation and deformation can occur.Pile foundation is adopted in the subway station more, and sedimentation and deformation is usually very little; And the interval subsoil that adopts of subway tunnel, sedimentation and deformation is relatively large, and decades even for many years, special soft clay area.
Subway tunnel Excessive Settlement distortion is the common disease of subway sectional tunnel engineering, particularly coastal riverine soft clay area or soft or hard stratum ecotone.It can cause that structure crack, the serious faulting of slab ends in section of jurisdiction, seal failure, ground water seepage, bolt corrosion, railway roadbed come to nothing, rail recessed (subsider), tread raise the sick evil of grade that transfinites.As untimely discovery or early warning, probably bring out operation and rock truck in shock, hole, be subjected to the security incident such as electric bad parking.As build up in the Shanghai Metro Line 1 of nineteen ninety-five Spring Festival in 2012 just because of the running tunnel sedimentation and deformation reach 10～15cm even the disease such as 20cm have to seal overhaul; The diseases such as the running tunnel sedimentation is excessive also appear in Guangzhou, Nanjing, Shenzhen successively, have to keep in repair.
Therefore, to going deep into that subway engineering is familiar with, the settlement observation of subway sectional tunnel more and more is subject to gerentocratic attention along with people.At present common engineering survey means are still used in the settlement observation of subway sectional tunnel, namely vertically at interval of tens meters, an observation station is set along the tunnel, utilize spirit-leveling instrument or total powerstation to carry out pointwise observation, analyze as calculated the settling amount (single settling amount and accumulative total settling amount) that obtains each point, judge whether whether it transfinites, affect metro operation and influence degree thereof.
But subway tunnel is different from ground surface works, adopts common engineering survey means often to be difficult to satisfy the observation work of present subway tunnel sedimentation.With respect to land subsidence observation, the subway tunnel settlement observation faces following problem usually: in (1) tunnel, sighting condition is poor.Even be also rather dark, be unfavorable for the observation of spirit-leveling instrument or total powerstation under the condition of turning on light.(2) in the hole, " time window " of observation is of short duration.Subway belongs to " enclosure space ", and the non-stoppage in transit period must not enter, and generally can only just permit entering at 1:00 AM to 4.(3) in the hole observation can only pass through the continuity carry out.All belong to the sedimentation and deformation district in the hole, unlike ground, several reference points can be set along the line, can carry out by multistage.(4) in the hole, the settlement observation branch is carried out.The common 20-40 rice of settlement observation dot spacing can be encrypted to 10 meters under specified conditions.Simultaneously observation station may not necessarily be arranged on sedimentation maximum point place.(5) each observation time continues longer.The subway tunnel interval mostly is the 1km left and right, and once observation needs 2-3 days.(6) even present automatic monitoring (" robot measurement " or static level observation) is also that fixing observation station (tens meters to tens meters of spacings) is observed, invest hugely, the while is also to carry out continuity settlement observation along the line.In view of These characteristics, subway tunnel settlement observation at present is limited to the interval paragraph that has been found that obvious sedimentation disease more, the settlement observation data do not possess measuring point continuity (the observation station spacing is very little) feature in the vertical, be unfavorable for overall understanding and whole assurance of sedimentation and deformation, easily cause dangerous situation to be omitted.
In sum, research and development explore a kind of technical feasibility, measuring point continuously, economical rationality, subway tunnel observation new technology easy and simple to handle, have important practical significance and far-reaching significance.
