Description
Technical field
The present invention relates to a kind of tests of the pore pressure of grouting in soil mass laboratory test test device, especially manipulated soil.
Background technique
The research of slip casting laboratory test is long-standing, and Germany, Austrian, the former Soviet Union scientist have carried out a lot rich in wound
The trial of meaning, it is general that ideal model of fissuration is made by concrete block, steel plate or groove profile ring, control slurries property and slip casting pressure
Power.Domestic scientist also carried out many practices, Southwest Jiaotong University-Zhang Baowen[1], Tongji University, Central South University-poplar
Level ground[8], world science and technology shaft building research institute-Gao Gangrong[9], coal science institute-Zhou Xingwang[6], Central South University-Yang Xiuzhu[3]Deng all once
The research of correlation test device was done, mainly there is plate, tubular type and square groove type three classes, it can using certain control device
Obtain the empirical equation under the conditions of different grouting pressures and slurries property.
The device used for the measurement of soil pressure in instrument and slurry pressure is mostly external pressure gauge, and slurry outlet passes through
Sebific duct connects pressure or stress test device, or built-in stress meter is controlled by computer in instrumentation, the third is then
Be soil model production after carry out aperture or again lay stress meter measure and control.First two mode high reliablity,
It is easily operated, but have fixed requirement for measurement position, specific position measurement has difficulties, the third is convenient, flexible, but is easy
Change the original property of the soil body, be affected by operation level, is more suitable for sand test.During making manipulated soil, soil
The control of body basic parameter (severe, moisture content, gradation etc.) and the combination of the above measuring instrument, which all exist, centainly to conflict.

Summary of the invention
The purpose of invention is
It carries out carrying out the variation test of Rock And Soil internal stress during simulation grouting test；Make heterogeneous soil indoor model
When be placed in inside soil body and compressed jointly with the soil body, the Parameters variations such as measurement resistance to shear of soil, pore water pressure.
Technical problems to be solved:
Existing common external pressure test device high reliablity, it is easily operated, but have fixed requirement for measurement position,
Specific position measurement has difficulties.Sand test is practical, and during making manipulated soil, (severe contains soil body basic parameter
Water rate, gradation etc.) control and the above measuring instrument combination all presence centainly conflict, the combination of measuring instrument and the soil body is general
It is difficult to keep the original state characteristic of contact surface.This experimental rig can measure for aperture is embedding, can also be in manipulated soil system
It is pre-buried during work, it is common to be pressurized, it is kept in contact face original state characteristic.
One, the general test method of grouting in soil mass test
When carrying out the test of general grouting in soil mass, need to carry out stress determination to inside soil body before carrying out grouting in soil mass test
, aperture first should be carried out to the soil body, instrument is put into aperture, fine sand is around filled up, sealing of hole is carried out with cement or cotton.
Two, heterogeneous soil model hole piezometry
1. " heterogeneous soil grouting simulation test device " is cooperated to use, pressure gauge is placed in assembled system soil in advance
Under frame, it is put into the native bucket of system.
2. it is more than pressure gauge height that deployed loose earth, which is uniformly introduced in earthenware processed, vibrates and tamp, removes frame
Frame vibrates uniformly again, smooth soil face.
3. cover board is placed on soil body surface, being densified to specific thicknesses with jack (may not exceed the maximum of pressure gauge
Compression height).Grouting test is carried out referring next to normal grouting test operating procedure and reads data.
The advantages of invention and good effect
1. soil body manufacturing process is simple, operation is can be completed in 1-2 people；Strong applicability is suitble to sand, loess, clay, sand ovum
The production of all kinds of soil models such as rock layers and complex earth filling.
2. slip casting process scalability is strong, slip casting process can be both manually controlled, information collecting device progress can also be increased
Computer control.
3. apparatus structure is simple, cleaning and maintenance easy to disassemble；Ensure soil structures by the reasonable dismounting of slip casting bucket
Integrality.
