Description
Technical field
The invention belongs to tunneling and underground engineering test apparatus technical field, in particular to a kind of inversion sample preparation measurement is special
The sample preparation device and test method of curved surface and Soil Interface adhesive force.
Background technique
As China central and east urban population is increasingly intensive, traffic condition growing tension, public transportation system at present compel to
Perfect, more than 20, China large- and-medium size cities also will start subway tunnel construction in the coming years at present.In densely populated prosperity
Downtown area carries out subway tunnel excavation, can neither use cut and cover tunneling, can not use mining method construction, best selection is exactly shield
Method.Shield machine is in shield tunneling process, due to the influence of each factor such as temperature or soil layer of different nature, in shield knife
On cutter and excavation face on disk under soil body continuous action, incrusted phenomenon can be generated on the cutterhead of shield machine, so as to cause
The decline of Tool in Cutting function and the generation of eccentric wear, while also will cause the increase of cutter head torque, driving progress is influenced when serious
Even stop work.Therefore, how precise measurement Soil adhesion power, be a kind of effective means for solving the problems, such as cutterhead mud lining.
Currently, the correlative study of existing adhesive force measurement device both at home and abroad, such as: in the 1950s, Foutaine exists
It is had developed in " Investigation into the mechanism of soil adhesion " text using circular metal plate as survey
The soil adhesion instrument of disk.The end of the seventies to the beginning of the eighties, Pan Jun save equal older generations' agricultural machinery expert in " 13 provinces and cities' water of south China
Field soil parameters investigation " text in have developed attached power, cohesion force detector outside SF-1 type soil.1984, Jiangsu Polytechnical College mulberry was just
In, Zhang Jixian et al. a kind of " hydraulic electric measuring type Soil adhesion is developed in " hydraulic electric measuring type soil adhesion force detector " text
Force detector " proposes that a kind of use hydraulic mechanism and vertical guide post are continuously pressed and unloaded, use in vertical direction to interface
Resistance strain gage beam type sensor obtains the Soil adhesion force detector for sticking force data.1993, Jilin Industry University
" the Soil adhesion force measuring instrument " that Ren Luquan et al. is developed in the patent of invention of " tester for soil viscosity force " uses combined type
It surveys disk and solves true adhesive force when attached power is greater than cohesive force outside soil and do not measure or indeterminable situation.In the middle and later periods nineties,
Computer technology is introduced into soil in " development of multifunction soil experimental bench " text by Jilin University Lu Shaofang, Shi Yaowu et al.
In the development of adherometer, the automation of soil adhesion instrument is tentatively realized.2002, Jilin University Wang Baisheng was in " soil adhesion
The research of characteristic test system " in text by repacking electronic universal tester, can be realized and transport triangular wave, sine wave etc. are different
Under flowing mode Soil adhesion power measurement, Jilin University Sun Lu in 2005 " soil adhesion characteristic test system sample frequency and
The research of control parameter " text in again the sample frequency of soil adhesion test macro and control parameter etc. have been made it is further complete
It is kind.But the research of these adhesive force measurement devices cannot effectively carry out the measurement of adhesive force under the influence of special surface,
Also it is not involved with the case where how making special surface accurately be bonded the soil body to be measured, drawing survey directly can not be carried out to special surface
Try soil body adhesive force.Traditional method for making sample uses and directly object under test such as cone and sphere is pressed directly into soil, it will to soil
Body is generated compared with large disturbances, and the soil body is caused to destroy, and the contact of the soil body and solid interface is uneven, and interface moisture moves
It moves；It is this influence to special surface object it is even more serious, or even cause curved surface with the soil body there are what large area was come to nothing to show
As, the measurement of special surface Yu Soil Interface adhesive force is leveraged, it is larger with really gap edge is sticked.
To overcome above-mentioned deficiency, the present invention proposes the sample preparation of a kind of inversion sample preparation measurement special surface and Soil Interface adhesive force
Device and test method by anastrophe sample preparation and directly carry out drawing to special surface device, analytical soil sample adhesive force size,
To provide effectively analysis foundation for the incrusted prevention and treatment of cutterhead.
