Embodiment
The utility model is further illustrated with implementation steps below in conjunction with the accompanying drawings.
As illustrated in fig. 1 and 2, a kind of induction type sediment thickness test device, the device are used for rotary digging, drilling and impact holing
Stake detects along depth direction pore size.Test device includes center-pole 1, magnetic induction ring 2, spacer 3, bar point 4, stepping electricity
Machine 5 and magnetic induction probe 6.Overhung construction of the center-pole 1 as whole device, the inner hollow of center-pole 1 are electric as circuit etc.
The installation site of element, water-proof function can be achieved after cavities seals.The bottom of center-pole 1 is tip, and bottom hole is sunk down into device
When can penetrate bottom sediment layer, realize and sink the measurement of thickness of slag layer to bottom.Magnetic induction ring 2, and magnetic are nested with outside center-pole 1
The internal diameter of inductance loop 2 is slightly larger than the external diameter of center-pole 1, enable magnetic induction ring 2 on center-pole 1 slidably.The center of sophisticated top
Spacer 3 is fixed with the outer wall of bar 1, for limiting the extreme lower position of magnetic induction ring 2.Spacer 3 can use ring segment or
The rod member of pin etc, if limit function can be realized, but the area of spacer 3 should be as far as possible small, in order to avoid to sophisticated pin
Enter sediment and bring resistance.But magnetic induction ring 2, in order to realize the effect floated on above sediment layer, its area should try one's best greatly.Stepping electricity
Machine 5 and magnetic induction probe 6 are arranged in the internal cavities of center-pole 1, the power output shaft of magnetic induction probe 6 and stepper motor 5
Connection, stepper motor 5 are used to drive magnetic induction probe 6 to move up and down in the cavity of center-pole 1.When magnetic induction probe 10 is advanced
During to magnetic induction 2 position of ring, magnetic induction probe earthward tester can send signal, thereby determine that position residing for magnetic induction ring 2
Put, and then obtain sediment layer surface position.
Test device should be nonferromugnetic material, such as aluminium, stainless steel from metal material.To avoid to magnetic induction ring
Read and disturbed in position；In order to keep magnetic induction probe 6 to be able to detect that the optional position of magnetic induction ring 2, magnetic strength should be kept
Should pop one's head in 6 movement travel minimum point be not higher than the movement travel of magnetic induction ring 2 minimum point.
Control unit is set in the internal cavities of center-pole 1, Automated condtrol is carried out to stepper motor 5, control unit can be with

Sediment thickness method of testing based on the device, comprises the following steps：
Test device is occupy bore central by step 1., is transferred vertically by lifting rope until bottom hole.As shown in figure 3, now
The indwelling of magnetic induction ring 2 is in sediment surface, and then pin enters sediment layer bottom for the bar of center-pole 1 point and spacer 3.Now magnetic induction ring 2
The distance of the bar point of distance center bar 1 can be considered as the thickness of sediment layer.
Step 2. Driving Stepping Motor 5 transfers magnetic induction probe 6, when magnetic induction probe 6 passes through magnetic induction ring 2, sends
First time signal；Magnetic induction probe 6 continues to explore downward to the intracavity bottom of center-pole 1.And whether magnetic induction probe 6 reaches center-pole 1
Intracavity bottom can be carried out really by way of setting pressure sensor in bottom or being converted by stepper motor rotating cycle
It is fixed.
Step 3. magnetic induction probe 6 makes motor overturning after exploring downward to the intracavity bottom of center-pole 1, and magnetic induction probe 6 is above carried,
During again by magnetic induction ring 2, second of signal is sent.According to motor test between signal twice and above carry distance (can pass through
Stepper motor rotating cycle converts), distance of the magnetic induction ring 2 apart from intracavity bottom is obtained, by the distance plus center-pole bar point
With intracavity bottom distance, that is, obtain bottom hole sediment thickness.
Step 4：After the completion of test, test equipment is proposed into pore-forming, and cleared up and safeguarded.
