Description of the drawings
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the structural schematic diagram of the liquefaction package of the utility model；
Including：Gas cylinder 11, measure and control device 12, flat chisel probe 13, rigid diaphragm 131, miniature vibrator 21, taper
Probe 22, blade 221, connecting plate 3.
Specific implementation mode
The utility model is further elaborated below in conjunction with attached drawing and specific example, but the utility model is not limited to
This specific examples.
The utility model is a kind of device for detecting property after non-liquefaction earth liquefies, including liquefaction package and flat chisel
Side is swollen test assembly two parts.
The liquefaction package includes：Drill bit, connecting plate 3 and the miniature vibrator 21 on drill bit.
Drill bit is used to take in instrument the designated position of the soil body, is made of metallic steel, the cone being preferably made of several blades
Shape drill bit 22.In the present embodiment, taper bit 22 is pyramid shape drill bit, and blade 221 is in decussation shape.
Miniature vibrator 21 is for making not liquefied soil body vibrations now, to enable the original not liquefied soil body generate liquid
Change.Miniature vibrator 21 is set to the knife spine position of taper bit 22.In the present embodiment, each blade 221 of taper bit 22
Knife spine be respectively arranged with miniature vibrator 21.Preferably, miniature vibrator 21 is arranged in 22 each blade of taper bit, 221 knife spine
Position by periphery.
Connecting plate 3 is made of metallic steel, for connecting taper bit 22 and flat chisel probe 13.
The Flat Dilatometer Test component includes：Gas cylinder 11, measure and control device 12 and flat chisel probe 13.
Flat chisel probe 13 is connected to 22 top of taper bit by connecting plate 3.Flat chisel probe 13 is using conventional existing city
Commodity are sold, there is the deformable rigid diaphragm 131 that is pressurized.Because when creeping into a part of soil body can generate taper bit 22
Larger gap, the blade parallel of 13 (planes of rigid diaphragm 131) and taper bit 22 if flat chisel is popped one's head in, flat chisel probe 13
Rigid diaphragm 131 cannot be close to the soil body.The knife of 13 (planes of rigid diaphragm 131) and taper bit 22 it is therefore preferred that flat chisel is popped one's head in
Plate plane intersects, best, is provided at the angular bisector of adjacent two blade 221, makes the rigid diaphragm 131 on flat chisel probe 13
The pedestal (pedestal is not shown) at 131 back side of rigid diaphragm by the pressuring action of soil pressure, can be close to.
Gas cylinder 11 makes 131 bulging of rigid diaphragm of flat chisel probe 13 for providing air pressure.
Measure and control device 12, for the size and reading data of control pressure, both ends are separately connected connection gas cylinder 11
With flat chisel probe 13.
In use, exploration sites selected first, conical probe 22, miniature vibrator 21 are assembled, by connecting plate 3 with
Start to tunnel after 13 connection of flat chisel probe.After reaching predetermined depth, starts miniature vibrator 21, the soil body is made to generate vibrations
Liquefaction.Miniature vibrator 21 is closed after liquefaction of soil mass, continuing drilling taper bit 22 makes flat chisel probe 13 reach what needs detected
Liquefaction position.11 air valve of gas cylinder is opened, the big of 131 inflation of rigid diaphragm and control pressure is made by measure and control device 12
It is small, reading A and B of 131 bulging of rigid diaphragm to apart from pedestal 0.05mm and 1.10mm when are read during inflation；Reduce gas
Pressure, diaphragm are shunk, and atmospheric pressure value when being retracted to apart from the pedestal positions 0.05mm is C readings.It can be calculated using the data obtained
The basic parameter for obtaining the soil body after liquefying, to obtain the liquefaction property of the soil body.
