Technical field
This utility model relates to a kind of detection equipment, particularly relates to a kind of infiltration experiment device in situ.
Background technology
The permeability of soil, is the complexity of Free water flowing in reflection soil, is one of native important indicator.In order to evaluate
Roadbed and the permeability of foundation soil body, need to carry out on-the-spot osmotic coefficient investigating.The mensuration of on-the-spot infiltration coefficient, monocycle of testing pits is noted
Water law, dicyclo water flood of testing pits, boring constant head water flood, boring precipitation head water flood, method etc. of drawing water.
Currently for the osmotic coefficient investigating of unsaturated soil, generally use dicyclo water flood of testing pits；During test, in test
An area testing pits not less than 1.0m*1.5m is excavated by desired depth in position, and dig down always warp is equal to outer shroud, deeply at the end, hole
The water storage hole of 15 20cm.Large and small steel loop is put in water storage hole so that it is concentrically justifying, bottom all spreads the gravel after 2cm, so
After in internal ring and two czermak spaces injected clear water to full；Laying bracket, is inverted on support after water supply bottle fills clear water, supplies water
The angle glass tubing of bottle inserts below the water surface between internal ring and two rings respectively.Record infiltration time started and the water level of water supply bottle
And temperature；After certain time, survey note and penetrated into the water yield in soil by water supply bottle, till stability of flow at this moment.From
After the water yield that water supply bottle flows out reaches to stablize, in 12 hours, survey note flow out the water yield at least 56 times.Survey every time and remember flow
10% is not should be greater than with the difference of meansigma methods.After experiment terminates, the water in sucking-off water storage hole, the outer boring in hole or under dig, determine water
Infiltrate the degree of depth.Count according to the time of drafting and infiltration capacity relation curve according to surveying, and ooze according to the calculating of infiltration coefficient computing formula
Coefficient thoroughly.
Current test method needs manual record infiltration time started, the water level of water supply bottle and temperature, during infiltration interval
Between, flow out the water yield, draw curve, calculate result of the test；Complex operation, time-consuming, arduously, and test data is easily by anthropic factor
Impact, result of the test is difficult to accurately objectively respond the permeability of soil.
