Description
Technical field
It the utility model is related to a kind of drawing out soil equipment, and in particular to a kind of to be answered for top layer, deep soil synchronized sampling
Attach together and put, belong to soil investigation sampling technique field.
Background technology
With urbanization, the frequent interference of the continuous acceleration and mankind's activity of process of industrialization, soil contamination problem is cured
Hair is serious.On April 17th, 2014, Environmental Protection Department and Ministry of Land and Resources, which combine, to issue《National Soil Pollution Investigation is public
Report》, investigation result shows：The total point position exceeding standard rate of national soil is 16.1%, wherein slightly, slightly, severe and serious pollution
Point position is respectively 11.2%, 2.3%, 1.5% and 1.1%, and soil environment situation totally allows of no optimist, and pollution control work is compeled
The eyebrows and eyelashes.
Apparent soil pollutant component and concentration are to formulate the basic premise of remediation contaminated soil measure, and pedotheque is adopted
Set analysis is to obtain soil physical chemistry natural disposition matter, the basic means of component characteristicses.Soil sample collector is the indispensability of collecting soil sample
One of instrument, the quality of its sampling performance determine the quality of sampling, close with the final accuracy for obtaining data and reliability
It is related.
Soil sampler has numerous species.Different samplers is selected according to different sampling analysis purposes.Gather farmland
Or wasteland topsoil sample, small-sized spades can be used；The general physical property of soil is studied, such as the soil weight, porosity and water holding
Characteristic etc., using cutting ring；Short handle earth boring auger may be selected in collection shallow-layer soil sample；1 meter or so soil layer interior profile feature of observation may be selected
Screw terminal earth boring auger；When collection is for chemical analysis or the soil sample for the physical analysis for being not required to undisturbed soil, with open type earth boring auger；Collection is not
Soil texture or the undisturbed soil sample of shape are destroyed, with telescopic earth boring auger；Contaminated site investigation in collecting soil sample frequently with
Directly promote the sampling appliance of rig.
The method that soil sample is carried out using direct Push Technology has been obtained a wide range of applications.But this direct press type takes
For quadrat method during promoting directly down, the frictional resistance of drill bit and soil is larger, causes the soil quilt into probe tube
Compression, causes more loose topsoil sampling rate relatively low.The low sampling rate of topsoil not only can be to the physics and chemistry of soil
Matter test is challenged, and also results in the judgement to pollution depth and error occurs.If topsoil sample is individually gathered, meeting
Additionally increase new sampling appliance, influence work on the spot efficiency.
Utility model content
Purpose of utility model：Technical problem to be solved in the utility model is in view of the shortcomings of the prior art, there is provided one
Kind directly promotes the device of soil sample, for top layer, deep soil synchronized sampling, ensure that sampling quality and operating efficiency,

Step 2：The device that step 1 combines is advanced into inside soil using direct press type sampling method, protection pipe is connected
Taken out with the first probe tube and retainer, obtain topsoil sample, outer drilling rod is with the first cut drill without being taken from soil
Go out；
Step 3：Interior drilling rod is connected with the second cut drill, the second probe tube is placed in inside interior drilling rod；
Step 4：The device of step 3 combination is inserted in outer drilling rod, continues to promote using direct press type sampling method downwards
Taken out after to soil target depth, the second probe tube is taken out, obtain deep soil sample.
Wherein, the depth that device promotes in step 2 is 1~2m.
Wherein, in step 4, the device of step 3 combination can continuously change several, the constantly sampling of progress deep soil
Operation, depth selection can reach 50m.
Beneficial effect：
1st, the application enters the diameter of soil sample mouth by increasing sampling cut drill, improves drill bit structure, reduces drilling rod insertion
To the compression of topsoil during soil, so as to improve the sampling rate of topsoil.
2nd, it is combined using double sampling cut drill, after topsoil is carried out using the first cut drill, only needs to take out
Probe tube, the second cut drill is subjected to deep soil sampling work through the first cut drill, easily carries out continuous soil
Earth sample collection, efficient quick, soil sample surrounding environment is destroyed small.
3rd, whole sampling work does not have to choose and change repeatedly drilling rod, only need to increase drill bit, extension arm can be connected
Continuous sample collection, operating efficiency that is time saving and energy saving, improving sampling.
