Description
Technical field
The present invention relates to subway tunnel structure monitoring disease field, more particularly, to a kind of subway tunnel structure seepage edema
Evil area features value measurement mechanism and method.
Background technology
Subway tunnel is the carrier of urban track traffic, and the work that can not be substituted is played in urban modernization process of construction
With.Subway tunnel investment is big, the investment of over ten billion Yuan easily；Influence to operation scope is big, and the stoppage in transit in a certain section of tunnel may all give
Upper hundreds of thousands of them's trip impacts.The main body of subway tunnel is artificial underground structure, in crude media environment, is being runed
In the diseases such as percolating water, lining cracking, lining corrosion occur.Safe, comfortable, normal fortune of these diseases with harm to tunnel
Battalion has a major impact and threatened.
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 two level waterproof.Whether District of Shanghai once divulged information to engineering, air force, season
State influence of the environmental conditions such as section, humidity, temperature on wet mark is very big, but the analysis Jing Guo big discharge observation data, in ventilation not
Well, in the case that technical interior humidity is larger, some valuable data have also been obtained：Every 5~6 drip about 1mL, per minute
The water percolating capacity of 2~3 drops is about suitable with the wet marks of 0.06m2.Therefore, the department such as railway, tunnel is judging whether an engineering reaches two
During level standard, specific index is as follows：Measure wet mark total amount area on any 100m2 water repellent areas, the maximum of single wet mark
Area, wet mark number.The accreditation of engineering circles has been obtained by the method judged These parameters.So provided during revision
Wet mark gross area value, single wet mark largest face product value and wet mark number are made on any 100m2 water repellent areas of engineering structure inwall
To judge whether engineering reaches the quantizating index of secondary standard；According to《Underground waterproof engineering inspection of quality specification》(GB50208-
2011) relevant regulations are detected for engineering leakage water, water amount of seepage detection principal character value includes：The maximum area of single wet stain
(unit：M2), total wet stain area (unit：M2), water percolating capacity (unit per 100m2：L/(m2.d))；Whole Engineering average infiltration
Measure (unit：(L/ (m2.d)), single leakage point maximum water leakage (unit：L/d)；Whole Engineering average water leakage (unit：
L/d)。
It can be seen that the judgement for the subway tunnel structure water leakage defect order of severity is main from above-mentioned national regulation
By seepage water area and percolating water measure of water the two characterizing magnitudes.According to《Underground waterproof engineering inspection of quality specification》
(GB50208-2011) it is mainly for the measuring method of percolating water water at present：The obvious water clock of the tunnel first half and continuously ooze
Stream, directly it can be measured with graduated container collection, or with the given size square frame with sealing edge mouth, installed in regulation measurement
Inner surface of tunnel, by percolating water import volume xylometer, then calculate 24h water amount of seepage；If detecting utensil or ascending a height has
When difficult, it is allowed to take the drippage number in per minute or several minutes by range estimation meter, calculate the leakage of the point.Generally, when
Dropleting speed 3 drips/min~4 drops/min when, 24h water percolating capacity is exactly 1L.When dropleting speed is more than 300 drops/min, then formation connects
Continuous line stream.But after rail traffic structure completion construction puts into effect, due to the particularity of rail transportation operation, realize above-mentioned
Method is measured so as to be difficult to implement to judge whether structurally waterproof requirement is up to standard for Tunnel Water Leakage water, according to《Ground
Iron design specification》(GB50157-2003) mentioned in：Every 5~6 drip about 1mL, the water percolating capacities of 2~3 drop per minute about with
The suitable value index definition of the wet marks of 0.06m2, the area by judging and measuring water leakage defect are to determine percolating water water mesh
Preceding maximally efficient, direct and feasible means.Tunnel defect investigation method traditional at present relies on artificial test mode,
Tunnel defect seepage water area is relied primarily in range estimation and micro-judgment on judging, is existed for measurement accuracy very big
Error.Therefore how effectively to realize that the area features value for water leakage defect measures during subway tunnel disease survey
Become the blank in field.
