Description
Technical field
This utility model belongs to field of civil engineering, relates to the measurement apparatus of a kind of soil-slope corrosion resistance, particularly relates to soil property
Side slope is the measurement apparatus of corrosion resistance in the case of Rainfall simulator erosion.
Background technology
As the construction material of slope project, road engineering and dyke building etc., the soil body is directly exposed in atmospheric environment.Soil
Moisture content alternately etc. affected by environmental change, precipitation, water level, slope table layer soil body is easily generated erosion and peels off and wash away etc. disease,
To such an extent as to rupture and peel off and then reduce engineering stability.Different from rock side slope, the most common disease of current soil-slope is
Domatic problem, along with extensive civil engineering construction, the domatic etch resistant properties of soil-slope reduce and cause slope disaster,
Localized landslip and overall landslide are more and more, cause economic loss serious harm people's life safety.The domatic disease of soil-slope is led to
In often the degree of depth is only limitted to climatic effect band (about 1.5-2m), etch resistant properties deficiency the disease caused is not according to natural conditions
With erosion being divided into peel off and wash away two kinds, there is certain difference in its formation mechenism.
Any position coming across side slope is peeled off in the erosion caused by sloping surfaces, and generally lamellar, flakey and bed separation, Crack cause includes
Domatic moisture humidity change (the dry and cracked peeling performance especially produced to tailo is the most prominent), toe draw action of compressive stress and air slaking
Drying shrinkage etc., the soil that usual silt content is many, soluble salt content is high easily produces to corrode and peels off.Domatic soil layer easy-weathering peels off opposite side
Slope is stablized unfavorable, particularly paleosol layer thicker and be positioned at during toe the most unfavorable；Domatic pull out type fracture is except forming spill at toe
Counter-slope landform slope stability is had certain impact, if being not added with leaving rainwater infiltration with protection, long-term slope stability can be made
Become tremendous influence；Domatic peeling Rock And Soil blocking gutter, the overall drainage performance of impact.
Slope wash refers to that rainfall and slope table current destroy the domatic top layer soil body and cause coombe, the phenomenon such as collapse of slipping.The work of soil-slope
Journey characteristic is that when being dried, intensity is higher, and structural deterioration after immersion, cohesive strength reduces rapidly, and amplitude of variation is big, and facile hydrolysis peels off.
Slope wash can cause substantial amounts of soil erosion, soil-slope slope wash and soil layer, soil nature, geographic and geomorphic conditions, hydrology bar
Parts etc. have close relationship.When rain time is concentrated or occurs with heavy rain form, and soil-slope is easily by rainwater and surface water
Destroy；When side slope uses stepped form to build, when drainage sunk well is unreasonable, the most easily cause erosion damage；After rainfall, domatic quilt
Scattered little runoff is washed into many fine and closely woven ditches, and the gradient is steeper and unvegetated domatic upper rill erosion is grown；When intermittent slope
Surface current concentrates water eroding and flooding, gradually forms shallow gully erosion and destroys domatic and platform.
Soil-slope erosion-resisting characteristics is not a simple physically or chemically index, but a comprehensive factor.Therefore,
Quantitative measurement soil-slope corrosion resistance is not easily accomplished.Existing all kinds of specifications not yet have evaluation soil-slope anti-erosion
Property test method, only have soil slaking test and side slope rain test can part measurement and reflection soil-slope anti-erosion
Property, the corrosion resistance of soil-slope can not be reflected completely, be only capable of reflecting these special circumstances under full water (washing away) state, logical
Cross and measure a certain parameter of domatic soil property as soil-slope domatic corrosion resistance index.
The ultimate principle of the slaking test of soil is to measure the change of volume in soil body disintegrating procedue, i.e. soil sample is put in process of the test
Enter the web plate central authorities in humidifying instrument, immerse in water drum rapidly, start stopwatch, the moment of scale at the neat water surface of floating drum when survey note starts
Stablize reading, then survey the reading of the note floating drum water surface according still further to different time intervals, calculate disintegrate amount and disintegration rate.By
Big in the changed measurement application condition of volume in process of the test, and perusal immediate reading need to be relied on, anthropic factor is compared
Many, result of calculation is the most inaccurate, owing to reading time interval is big, can not be predicted the Scouring Characteristic of soil-slope.
Side slope rain test is the one of on-the-spot test, carries out rain making washout test by field engineering test section, obtains
Different slope erosion destructive processs and antiscour effect thereof.Ordinary test needs to measure 4 contents: before (1) measuring rainfall,
Rear and during the change of moisture content of slope soil；(2) measure the time forming rainwash；(3) measure at different periods water sample
Clay content；(4) observe formation and the Evolution of slope erosion ditch.Rainfall simulator typically uses faces upward spray formula simulated rainfall machine.
The height of rainfall shower nozzle freely can regulate according to practical situation, reaches 80% to the similar performance of natural rainfall.On-the-spot rain test
Can complete side slope is washed away case study more really, but rainstorm mechanism and rainfall size form have certain district with natural rainfall
Not, it is impossible to right-on reflection practical problem, and test complicated loaded down with trivial details costly.
