Rice or so.The scupper substantially moves towards direction arrangement along inter-laminar dislocation band C2, the thickness of the inter-laminar dislocation band 12 of exposure in cavern
Degree is 10-30 centimetres, and apart from 1.2-2 meters of bottom plate, which is mainly that landwaste presss from both sides chamotte mould, and upper disk is basalt, compared with
Lower wall is complete；Lower wall is tufa stone, is in cleavage fracture state；Chip off-falling easily occurs for the rock mass near inter-laminar dislocation band, and wall caving is seeped
Water, the disasters such as activation sliding, easily causes engineering accident；Its deformation failure stability problem be the main bugbear that faces of power station it
One；For the shearing mechanical characteristic for preferably studying inter-laminar dislocation band, as shown in Fig. 5, using a kind of layer described in the utility model
Between disturbed belt undisturbed soil sampling device be sampled, shown in specific step is as follows:
1): selecting water content larger part in cavern 11, especially there is the typical inter-laminar dislocation band 12 at water infiltration to be frozen
Connection sampling, and exclusion two in advance is helped and top plate loosens sillar；
2): rigging up fixed platform (i.e. bracket), and drilling machine is positioned；
3): on cavern's abutment wall by wait materials a little centered on 13 with impact drill interval 60 ° make a call to 6 prebored holes 14, hole in advance
Deep about 250mm, diameter about 20mm, drilling tilt down 15 ° or so, and the specific arrangement mode of prebored hole 14 is as shown in Figure 6；
4): being pressurized liquid nitrogen pump 10 using hand-pinch type, liquid nitrogen is pumped into prebored hole by drain pipe, when liquid nitrogen is from hole
When outflow, extracts drain pipe and block prebored hole with stopper, continue to be pumped into liquid nitrogen into next prebored hole 14；
5): by boring one 10 millimeters of hole and checking refrigerating effect with temperature measurer thermometric, guarantee in prebored hole perturbing area
Freeze space temperature is lower than zero degree；
6): drilling through rock (soil) core；During drilling through sample, due to sampler barrel frictional heat generation, refrigerating effect can be reduced,
The temperature shown by checking temperature measurer, decides whether to be pumped into liquid nitrogen into hole；
7): after getting into desired depth, drilling machine is closed, drilling pipe is unloaded from drilling machine, backs out the detachable type drill in drilling pipe,
Frozen sample is taken out；
8): frozen sample being wound rapidly to preservative film sealing, and is put it into prefabricated metal bucket, it is allowed to solve naturally
Freeze, the moisture that fresh-keeping film surface liquefaction generates is wiped after defrosting and seals with wax.
Conclusion: the non-disturbance undisturbed sample of the inter-laminar dislocation band of acquirement can reflect the reset condition of disturbed belt to the greatest extent,
Development for mechanical test in inter-laminar dislocation band room provides guarantee.
In order to more clearly illustrate a kind of inter-laminar dislocation band undisturbed soil sampling device described in the utility model with
Existing inter-laminar dislocation band undisturbed soil sampling device compares possessed advantage, and staff carries out both technical solutions
Comparison, comparing result are as follows:
As seen from the above table, a kind of inter-laminar dislocation band undisturbed soil sampling device described in the utility model and existing interlayer are wrong
Dynamic band undisturbed soil sampling device is compared, and the integrality materialsed is preferable, and sampling efficiency is higher, labor intensity is smaller.
