Description
Technical field
The present invention relates to subway tunnel structure monitoring disease field, especially relate to a kind of subway tunnel structure water leakage defect area features value measurement mechanism and method.
Background technology
Subway tunnel is the carrier of urban track traffic, plays the effect that can not be substituted in urban modernization process of construction.Subway tunnel investment is large, the investment of over ten billion Yuan easily; Influence to operation scope is large, and the stoppage in transit in a certain section of tunnel impacts all may to upper hundreds of thousands of them trip.The main body of subway tunnel is artificial underground structure, is in crude media environment, there will be the diseases such as percolating water, lining cracking, lining corrosion in operation.These diseases and harm have material impact and threat to safe, comfortable, the normal operation in tunnel.
According to current existing national regulation " metro design code " (GB50157-2003) for waterproof disease related request, track traffic regional tunnel classification of waterproof should be defined as secondary waterproof.Whether District of Shanghai once ventilated to engineering, the state impact of the environmental baselines such as air force, season, humidity, temperature on wet mark is very large, but through the analysis of a large amount of observation data, when drawing badly, technical interior humidity larger, have also been obtained some valuable data: every 5 ~ 6 drip is about 1mL, the water percolating capacity of 2 ~ 3 per minute mark that about wets with 0.06m2 is suitable.Therefore, the department such as railway, tunnel is when judging whether an engineering reaches secondary standard, and concrete index is as follows: measure the wet mark total amount area on any 100m2 water repellent area, the maximum area of single wet mark, wet mark number.The accreditation of engineering circles has been obtained by the method judged These parameters.Wet mark total area value, single wet mark largest face product value and wet mark number as judging whether engineering reaches the quantizating index of secondary standard so define during revision on any 100m2 of engineering structure inwall water repellent area; Detect relevant regulations according to " underground waterproof engineering inspection of quality specification " (GB50208-2011) for engineering leakage water, water amount of seepage detects principal character value and comprises: the water percolating capacity (unit: L/ (m2.d)) of the maximum area (unit: m2) of single wet stain, total wet stain area (unit: m2), every 100m2; Whole Engineering average water percolating capacity (unit: the maximum water leakage (unit: L/d) of (L/ (m2.d)), single leakage point; Whole Engineering average water leakage (unit: L/d).
Can find out that from above-mentioned national regulation the judgement for the subway tunnel structure water leakage defect order of severity mainly relies on percolating water area and these two characterizing magnitudes of percolating water measure of water.According to " underground waterproof engineering inspection of quality specification " (GB50208-2011) current measuring method for the percolating water water yield mainly: the obvious water clock of the tunnel first half and continuous seepage flow, can directly measure with graduated container collection, or with the given size square frame with sealing edge mouth, be arranged on the inner surface of tunnel that regulation measures, by in percolating water import volume xylometer, then calculate the water amount of seepage of 24h; If detect utensil or ascend a height when having any problem, allow to count by range estimation the drippage number got in per minute or several minutes, calculate the leakage of this point.Usually, as dropleting speed 3/min ~ 4 droplet/min, the water percolating capacity of 24h is exactly 1L.When dropleting speed is greater than 300/min, then form continuous linear flow.But when rail traffic structure completes after construction puts into effect, due to the singularity of rail transportation operation, realize said method the Tunnel Water Leakage water yield to be carried out measuring thus judges that whether structurally waterproof requirement is up to standard and be difficult to implement, mentioned by " metro design code " (GB50157-2003): every 5 ~ 6 drip is about 1mL, the water percolating capacity of 2 ~ 3 per minute about wets with 0.06m2 the suitable value index definition of mark, is the means determining that the percolating water water yield is the most effective, direct and feasible at present by the area judged and measure water leakage defect.Tunnel defect investigation method traditional at present relies on artificial test mode, is mainly fixed against range estimation and micro-judgment, for measuring accuracy, there is very large error on tunnel defect percolating water area judges.Therefore the how effective blank realizing the area features value measurement of water leakage defect being become in field in subway tunnel disease survey process.
