Description

One kind slurry arteries and veins-ground interface strength test instrument and method of testing
Technical field
The present invention relates to a kind of tester for testing slurry arteries and veins-ground boundary surface intensity, and in particular to one kind can be true The real crustal stress condition reproduced in Practical Project, obtains the test device of the slurry full-time empty intensity variation curve of arteries and veins-ground interface With method of testing.
Background technology
In recent years, along with the fast development of the Hydraulic and Hydro-Power Engineerings such as China Express Railway, highway, work is descended in large quantities Cheng Zhankai builds, but water bursting factor phenomenon takes place frequently in process of construction, causes mass casualties, property loss.According to statistics, The occurrence frequency of water bursting factor disaster comes second in underground engineering accident, the economic loss and casualties ranking for causing First.
Proved by a large amount of engineering practices, the slurry injection technique in underground engineering can be carried out effectively to the prominent mud disaster of gushing water Administer, by special slip casting pipeline, slurries by certain pressure to permeate, fill, cleave, the form such as densification enter weak broken Rock And Soil, improves Rock And Soil physical and mechanical parameter and performance, so as to ensure the smooth excavation of underground engineering so as to reach.
Wherein fracture grouting due to grouting pressure it is larger, so in engineering note to the improved effect of the weak rocks soil body preferably Extensive use in slurry.Slurry arteries and veins cleaves Rock And Soil under high pressure effect, forms slurry arteries and veins skeleton and slurries-Rock And Soil interface.Its Middle slurry arteries and veins-Rock And Soil boundary strength is to weigh the important parameter of fracture grouting effect, is the important ginseng for carrying out grouting program design Examine index.Set up a kind of tester of the slurries-Rock And Soil boundary surface intensity that can reproduce true engineering ground stress condition with Method of testing is problem demanding prompt solution, can effectively fill up the technological gap in this field.
Current method of testing is primarily present problems with:
1st, real crustal stress condition cannot be loaded, boundary strength mainly carries out theory on the basis of preliminary experiment and pushes away Lead, error is big, and reference value is not strong.
2nd, the total space intensity variation curve of slurry arteries and veins-ground body interface can not be obtained, it is impossible to obtain necessary key parameter.
3rd, in test process, it is impossible to measure the residual strength at slurry-rock interface, influence grouting program design.
4th, the full destructive process at the description slurry-rock interface without standard measure.
5th, in process of the test, main using artificial loading, the research technique of manual record, loading procedure is unstable, uneven It is even, experimental result is disturbed larger.
The content of the invention
To solve deficiencies of the prior art, the present invention provides a kind of slurry for loading differently stress condition Arteries and veins-ground interface strength test instrument and method of testing
