Use procedure:
Excavate groove in position, roadbed measured point along transversal section, sedimentation water tumbler 1 and connecting pipe 2 are put into groove, measuring system 3 is fixedly installed on the observation pier 33 outside roadbed toe.In this step, elder generation is direct to be imbedded observation pier 33 in the ground of roadbed toe, then surveyors' staff 31 and measuring tube 32 is fixed on observation pier 33.Channel excavation should arrange the gradient of the downward 3%-5% to toe direction, first should cover the sand of one deck 5cm ~ 10cm, fill out subgrade soils again after compacting during backfill, finally by groove compacting, guarantees that the connecting pipe 2 of rising pipe 15 can draining smoothly.Be tightly connected with water inlet pipe 14, rising pipe 15 and gas outlet 16 respectively one end of connecting pipe 2, the other end of connecting pipe 2 stretches out outside groove, is communicated with measuring tube 32, vacuum extractor 4 and outside air respectively by valve.Backfill compacting groove, what make that sedimentation water tumbler 1 and connecting pipe 2 can be stable is fixed in roadbed, ensures the stability measured and accuracy.After backfill is good, sedimentation water tumbler 1 submerges in roadbed completely, and the upper surface of observation pier 33 in measuring system 3 is positioned at the below of connecting pipe 2 port.
Open water inlet pipe valve 51, measuring tube valve 52 and water storage barrel connecting pipe valve 53, slow water filling in measuring tube 32, observe the water outlet situation of rising pipe 15 from observation Dun33Chu, after water inlet pipe 14 starts water outlet, close water inlet pipe valve 51, continue to measuring tube 32 slowly water filling; After water is full of water storage barrel connecting pipe, the water storage barrel connecting pipe other end is placed in water storage barrel 6.
Close measuring tube valve, continue water filling in measuring tube 32 and make its water level higher, treat that follow-up measuring process uses.
Close the valve of connecting pipe 2 port is connected with gas outlet 16, make cup 11 be in air-tight state, use vacuum extractor 4 to bleed from rising pipe 15 uninterruptedly subsequently, until after cup 11 and the interior formation vacuum of connecting pipe 2, open water inlet pipe valve 51.In abovementioned steps, because the flow velocity of water in water inlet pipe 14 and connecting pipe 2 is unhappy, after current, tube wall can adhere to a lot of bubble, and after placement after a while, bubble can break again, air wherein overflows from water, changes the liquid level of Guan Zhongshui, is unfavorable for the accuracy measured.Now, the negative pressure state formed in cup 11, and water inlet pipe, can keep the liquid in water inlet pipe 14 to be in the highest liquid level all the time in pipeline, and can accelerate the spilling that makes to there is air in water, ensure that the accuracy of measurement result.
Observe the water outlet situation of rising pipe 15 from observation Dun33Chu, after rising pipe 15 starts water outlet, slow down the speed of evacuation until stop, closing water storage barrel connecting pipe valve 53.Owing to there being the existence of negative pressure state, the flow velocity of current in comparatively elongated pipeline can also being accelerated, water is flowed out smoothly, the probability of bubbles attached on tube wall can also be reduced, reduce the bubble existed in water further.
Open the valve on the connecting pipe 2 that is connected with gas outlet 16 and measuring tube valve 52, slowly add water in measuring tube 32, continue to add water after water outlet stablized by rising pipe 15 and be no less than 50ml, the time of liquid level stabilizing is no less than 5min, stop afterwards adding water, after buret 32 liquid level stabilizing to be measured, read measuring tube middle water level height.
Again slowly add water in measuring tube 32 and be no less than 50ml, the time of liquid level stabilizing is no less than 5min, and reading again after liquid level stabilizing, until adjacent twice difference of reading is not more than 1mm, reading last numerical value is this survey measurements.Because when installing, the benchmark elevation of surveyors' staff 31 is relatively higher than the bottom of measuring tube 32, therefore the reading of measuring tube 32 liquid level measures measuring point elevation with observing the elevation of observation mark on pier be added being this time.Through repetitive measurement, can obtain elevation numerical value more accurately, the error produced when effectively reducing reading, makes measurement structure more accurate.
After measurement completes, stop to measuring tube 32 water filling, until the connecting pipe 2 no longer water outlet of rising pipe 15, disconnect water inlet pipe 14 and the connection of measuring system 3, vacuum extractor 4, measuring tube 32 and 3-way valve door 5 are removed, install again when next time measures and uses; Protect the nylon tube head of the connecting pipe 2 be connected with gas outlet 16, rising pipe 15 and water inlet pipe 14; Groove structure above observation pier 33 is then built to be protected.When again carrying out settlement observation, repeat steps A-H, when adopting level method to measure liquid level, level method is utilized to read liquid level in measuring tube 32, the elevation that can obtain liquid level in measuring chamber is added with the dip stick benchmark elevation measured with leveling measuring method, by the liquid level elevation of law of connected vessels just known another port (measuring point), twice measurement in front and back obtains the difference of elevation, is the settling amount of measured point.
Technique scheme utilizes law of connected vessels, buries sedimentation water tumbler in roadbed or on ground underground, take water as medium, carries out settlement observation by measuring system 3, connects sedimentation water tumbler 1 and measuring system 3 by connecting pipe 2.Observing without construction hindered falling of construction period can be realized, also can carry out the long-term observation of operating period, there is cost low, pollution-free, advantage simple to operation.
