Description
Technical field
But the present invention relates to a kind of environment probe of on-the-spot test soil body pH value, belong to a kind of static sounding device that can detect underground soil body Acidity of Aikalinity in Geotechnical Engineering and the field of environment engineering.
Background technology
Along with rapid economy development; The quickening of urbanization and process of industrialization; Place soil pollutes more and more serious, and the ground circle environment that we depend on for existence goes from bad to worse, and environmental geotechnical engineering problems has become China's Geotechnical Engineering and environmental engineering worker important research project.Because the immersion of acid rain, the potential of hydrogen of the soil body can change.The potential of hydrogen of the general soil body is all passed through on-site sampling, takes pH appearance or acidometer to measure the pH value of soil sample in the laboratory, the pH value of also available " wide model test paper colourimetry " simple measuring soil.The method is because the disturbance of sampling like this, often test value distortion, moreover in the transportation soil sample process since the forfeiture of moisture certainly will impact soil body ions content.The potential of hydrogen on-the-spot test of the at present external soil body is measured through the pH meter that is installed on the static sounding surface.Its maximum defective is that the pore water in the soil clamp-ons test chamber, has the process of pore pressure dissipation.The pH value realizes this process for for the low-permeability soil body the clay, being difficult to test accurately, all must clean behind the each reading of pH meter in addition.And pH meter is prone to produce wear-out failure.The present invention is installed on pH meter in the rear groove that measure to survey the friction resistance sensor, and probe penetration process mesoporosity water forms eddy current at groove, can be so that pH meter METHOD FOR CONTINUOUS DETERMINATION soil body hole liquid potential of hydrogen, and protect instrument to avoid wearing and tearing effectively.Continuous pH value section can judge effectively that the pH value exists the responsive soil body that changes to pollute when contaminated, and accurately judges and confirm that chemical reaction is taking place for it.
The present invention is based on conventional hole and press static sounding probe, proposed a kind of can be convenient, fast, the instrument of in-situ test pH value that testing cost is cheap, for the evaluation of underground soil body Acidity of Aikalinity provides test parameter efficiently and effectively.
Summary of the invention
Technical matters:The technical matters that the present invention will solve is to the domestic original position evaluation that can't carry out soil body Acidity of Aikalinity, proposes a kind of environment hole that can be used for the soil body the tested pH value of environmental area and presses static sounding probe.Utilize this probe can judge effectively that the pH value exists the responsive soil body that changes to pollute when contaminated, and accurately judge and confirm that chemical reaction is taking place for it.
Technical scheme:Static sounding probe is pressed in the environment hole of surveying soil body pH value of the present invention, and the top in its probe is provided with pH value test chamber and pH value meter; The bottom of probe is provided with tiltmeter and 3-component earthquake detector; Bottom at 3-component earthquake detector is provided with temperature sensor; In the bottom of temperature sensor is friction cylinder, below friction cylinder, is connected with probe, and hole press filtration ring is positioned at the junction of friction cylinder and probe; The feeler inspection probe is identical with the feeler lever diameter, and this probe probe top connects feeler lever.
The cone angle of circular cone probe is 60 °, and the awl basal cross section is long-pending to be 10 cm
2, the friction cylinder surface area is 150 cm
2
Hole press filtration ring thickness is 5 mm, and probe useful area ratio is 0.8.
3-component earthquake detector: natural frequency 100HZ/60HZ, sensitivity 104mV/kine, impedance 215 Ω.
Tiltmeter: drift angle measurement range: 0 °～15 °; Precision: ± 0.1 °; Drift angle resolution: 0.01 °;
The pH range ability of pH value meter: 0-14; Moisture scope: 1-8%; PH measuring accuracy: ± 0.2; Moisture precision: ± 1%; Environment temperature: 5-50 ℃.
Beneficial effect:The invention solves the quiet spy of domestic existing single doube bridge technology and can not detect the defective of underground soil body pH value, potential of hydrogen that can the effective evaluation soil body, thus whether and kind the existence of pollutant in the judgement soil body.
