Wherein, in the utility model embodiment, level sensing module 200 is used to detect from water body to be measured
Depth, for example, level sensing module 200 can be liquid level sensor, it is preferable that throw-in type liquid level sensor can be used;
Wherein, in the utility model embodiment, penetration resistance detection module 300 is used to examine in injection water body to be measured
Penetration resistance is surveyed, for example, penetration resistance detection module 300 can be pressure sensor, it is preferable that ceramic pressure can be used to pass
Sensor;
For example, liquid level sensor, pressure sensor can be arranged on a body of rod, pressure sensor is located at the bottom of the body of rod
End;
Because different objects attribute is different, the bearing capacity having is different, and the relation between bearing capacity and specific penetration resistance is such as
Shown in lower:
Fk=aPs+b
Wherein:FkIt is object bearing capacity, PsIt is specific penetration resistance, refers to suffered during the probe injection object of pressure sensor
Total penetration resistance and probe plane projected area business, a, b are constant;
As shown from the above formula, it is linear between object bearing capacity and specific penetration resistance, the bearing capacity of different objects
Difference, the mutation of penetration resistance can be determined by the probe of pressure sensor, to determine the institute of the interface between different objects
The position at place.
When being detected to water body to be measured, the above-mentioned body of rod can with the uniform velocity state injection water body to be measured, due to air,
Water, mud, the bearing capacity of hardcore below mud are different, therefore, during body of rod injection water body to be measured, pressure
Penetration resistance suffered by the probe of sensor also differs, when pressure sensor injection to air and water surface intersection, pressure
Promutation (being referred to as the first catastrophe point) can occur for the pressure value (namely penetration resistance) of force snesor detection, when pressure passes
During sensor injection to water and mud intersection (namely at the top of mud), the pressure value of pressure sensor detection can occur second
Secondary mutation (be referred to as the second catastrophe point), when pressure sensor injection to mud and hardcore intersection (namely mud bottom
Portion) when, third time mutation (being referred to as the 3rd catastrophe point) can occur for the pressure value of pressure sensor detection, therefore can be according to pressure
The penetration resistance of force snesor detection determines pressure sensor, and whether injection is at the top of mud and whether injection is to mud
Bottom, specifically, rational threshold value can be set beforehand through experimental data, further according to the pressure value changes of pressure sensor detection

Referring to Fig. 2, in penetration resistance detection module injection water body to be measured after, as depth of penetration increases, penetration resistance
Slowly increase is (during 1-19), until in water and mud intersection, above-mentioned telomutation (during 19-21) being produced, in injection
After resistance detection module enters mud, because mud density gradually increases, penetration resistance value can comparatively faster increase
(during 21-36), but numerical value is consecutive variations, when touching the hardcore of water body to be measured, is pressed because operating personnel apply
Power reason, penetration resistance value can produce a larger mutation (during 36-37), now produce above-mentioned third time mutation, drawing
Go out during measuring staff, penetration resistance detection module is among water or mud, can by a pressure value, but pressure value compared with
It is small.
Liquid level sensor is used to detect from the depth in water body to be measured, it is necessary to which explanation, enters to water body to be measured
In row detection process, at the top of pressure sensor (i.e. penetration resistance detection module) injection mud (namely during second catastrophe point)
During with mud bottom (namely during three catastrophe points), it is required to ensure liquid level sensor (i.e. level sensing module) positioned to be measured
,, can be according to the inspection of liquid level sensor in the second catastrophe point by the detection data of combination pressure sensor in the water of water body
Data calculation pressure sensors probe is surveyed to the distance (i.e. the top depth of mud) of the water surface, can be with three catastrophe points
According to the data calculation pressure sensor probe that liquid level sensor detects to the distance (i.e. the bottom depth of mud) of the water surface, tool
Body, it is assumed that the distance between liquid level sensor and pressure sensor are s, then mud top depth Hm1, mud bottom
Portion's depth Hm2Respectively:
Hm1=Hk1+s;
Hm2=Hk2+s;
Wherein, Hk1Liquid level sensor is in water body to be measured during at the top of the mud of pressure sensor injection to water body to be measured
Depth, Hk2For when the mud bottom of pressure sensor injection to water body to be measured liquid level sensor in the depth of water body to be measured
Degree;
The then silt depth H of water body to be measuredΔ=| Hm2-Hm1|=| Hk2-Hk1|。
