Logical) time be 10 seconds.Sedimentary sample receiving tube 12 in first sampling groove 14a is accessed.Said process is
Second collection sedimentary section process.The double sampling time of the present embodiment 1 is 10 minutes and 20 minutes.
Contrast test：
As the translational speed of cutting plate 11 is larger on the physical index impact for gathering sedimentary, contrast test is adopted
With with embodiment 1 and the mud of the identical moisture content of embodiment 2, and mutually gathering sedimentary in the same time, but adopt
Different 11 translational speeds of cutting plate.
A kind of method for gathering sedimentary section during mud deposition test, which comprises the following steps：
Step (1) to (3) is with embodiment 1；
(4) sedimentary section is gathered
Before collection sedimentary, rotary control valve 4 start change gear box 3 make the first upper stop piece 8a, on second
Catch 8b, sealing ring 9 and steel disc 10 rise in the second outer tube 6b, and then promote deposition cylinder 7 to move upwards
Dynamic, scale 17 is observed, when sample position rises at the second sampling groove 14b control valve 4 of stopping the rotation.
Using the cutting plate in collection sedimentary tomography apparatus during a kind of mud deposition test shown in Fig. 2
It is acquired sedimentary.During deposition test, cylinder 7 and the upper and lower UNICOM of the second sampling groove 14b is deposited, is used during sampling
Hand promotes the cutting edge of cutting plate 11, cutting plate 11 move and promote sinking for the second sampling groove 14b from left to right
Lamination is slided to the right, the first telescopic spring cap 16a with spring, second spring flexible cap 16b, the 3rd bullet
Spring stretch cap 16c, the 4th telescopic spring cap 16d all snap in respectively the 5th circular hole 15e, the 6th circular hole 15f,
In 7th circular hole 15g, the 8th circular hole 15h, cylinder 7 and the upper and lower UNICOM of the first sampling groove 14a is now deposited.Push away
Dynamic cutting plate 11 reaches the time of specified location (i.e. deposition cylinder 7 and the upper and lower UNICOM of the first sampling groove 14a) and is
20 seconds.Sedimentary sample receiving tube 12 in second sampling groove 14b is accessed.Said process is heavy for gathering for the first time
Lamination section process.
When second sedimentary collection is carried out, rotary control valve 4 starts change gear box 3 makes the first upper stop piece
8a, the second upper stop piece 8b, sealing ring 9 and steel disc 10 are risen or fallen in the second outer tube 6b, and then are pushed away
Dynamic deposition cylinder 7 is moved up or down, and observes scale 17, when sample position rises to the first sampling groove 14a
Place stops the rotation control valve 4.Through first time collection sedimentary, deposition cylinder 7 is upper and lower with the first sampling groove 14a
UNICOM, promotes cutting plate 11 from right to left with hand during sampling, and the cutting edge of cutting plate 11 can be moved and promote first
The sedimentary of sampling groove 14a is slided to the right, and the first telescopic spring cap 16a with spring, second spring are stretched
Cap 16b, the 3rd telescopic spring cap 16c, the 4th telescopic spring cap 16d all snap in respectively the first circular hole 15a,
In second circular hole 15b, the 3rd circular hole 15c, the 4th circular hole 15d, cylinder 7 and the second sampling groove 14b is now deposited
Upper and lower UNICOM.Promote cutting plate 11 to reach specified location and (deposit cylinder 7 and the second sampling groove 14b up and down
Logical) time be 20 seconds.Sedimentary sample receiving tube 12 in first sampling groove 14a is accessed.Said process is
Second collection sedimentary section process.The double sampling time of the present embodiment 1 is 10 minutes and 20 minutes.
The moisture content of embodiment 1, embodiment 2 and contrast test collection sedimentary sample is as shown in figure 5, permissible
It was found that, no matter the first sub-sampling or the second sub-sampling, the sedimentary sample that embodiment 1 is obtained with embodiment 2
Moisture content closely, but significantly greater than contrast test obtain sedimentary sample moisture content, this is primarily due to right
Slower than promoting the speed of cutting plate 11 in test, cause during cutting plate 11 is promoted, the first sampling groove
Mud in 14a and the second sampling groove 14b is cut in promotion still in deposition process, i.e. sedimentary sample moisture content
It is gradually reduced when cutting plate 11, this causes the sedimentary sample moisture content that contrast test is obtained less than normal.Permissible
Find out, it is optimum that the 1st embodiment adopts the traveling time of cutting plate 11 with the 2nd embodiment, i.e., in the application
The traveling time of cutting plate 11 is optimal selection.
The preferred embodiments of the present invention are the foregoing is only, invention is not limited to, every according to this
Bright essence makes any simple modification, change and equivalent structure transformation to above example, all still belongs to skill of the present invention
In the protection domain of art scheme.
