Description
Technical field
The present invention relates to test Hydraulie Conductivity of Geotetile technical field, specially a kind of geotextiles silting and permeability mould
Draft experiment device.
Background technique
In the slope project of mine and highway, it is necessary to which the drainage pipe of embedded package different type geotextiles is to reduce side slope
In level of ground water, avoid destroying because of the excessively high initiation slope instability of water level.Drainage pipe, can be because of soil after the long-time service of decades
Work cloth surface, which generates silting deposition, to cause to fail, and underground water can not flow out.To analyze this deposition silting mechanism, need to carry out interior
Simulated experiment discloses the silting process and influence factor of geotextiles, the changing rule of its permeability of synchronism detection, to be the later period
Design and the silting prevention and treatment of drainage pipe provide basis.
Test to all kinds of soil bodys and geotextiles permeability, technology is mature at present, mainly uses two methods, i.e., often
Head permeability test and variable head permeability test, and form national standard (GB/T 15789-2016, geotextiles and its related
The test of vertical Penetration Signature when product is zero load；GB/T 50123-1999, Standard for test methods of earthworks).The main original of test
Reason is the volume by passing through the water of vertical direction sample in cooling water of units of measurement time, calculates and obtains infiltration coefficient.It is for infiltration
The biggish sample of number, generallys use hydrostatic head method, and the sample small for infiltration coefficient then preferably uses variable water level method to test.According to
When national standard is tested, properties of samples is uniform to be existed without interlayer.
To geotextiles silting phenomenon and mechanism study, usually carried out using simulating lab test.Domestic easily China is strong etc.
(2005), (2011), Gu Gaoli etc. such as (2008), Wu Jun etc. such as Jiang Long etc. (2006), Zhang Guojun (2008), Duan Xiangbao
(2011), Hu Xuetao etc. (2012) and Li Shibo etc. (2013) devise it is suitable for oneself research field, can carry out
The experimental provision that permeability is tested after silting.These devices generally include water circulation system (pump pressurizing unit, water inlet pipe, water outlet
Pipe and connecting pipeline), sand and geotextiles sample filling system, several parts such as pressure and infiltration monitoring system.Water inlet system
Be divided into two classes: 1) from bottom apply high pressure make water from water storage container enter experimental channel again from top flow out, then fluid into
Enter post-processing stages, when the method tests permeability, the hydraulic pressure of application needs to be greater than gravity, and when calculating is the equal of that constant head is surveyed
The mutation method of examination needs to take into account the pressure of application in formula；2) water is promoted to using peristaltic pump disposed above
Water tank, then water carries out experimental channel from water tank, penetrates filler under Gravitative Loads, flows out from outlet at bottom, then
Carry out the post analysis stage.According to experiment purpose difference, arrangement geotechnique is distributed in duct bottom in part Experiment pipeline, and part is directly
Filling sand is not laid with geotextiles, only one layer of experimental channel, is disposed with pressure monitor system in side wall some.
In terms of existing technology, when carrying out penetration clogging experiment to earthen materia, various experimental facilities can carry out single
The permeability of filler is tested, and in use, there are problems that the following aspects: 1) great soil group filled in experiment is
Homogeneous material, if material is multilayer, the material permeability coefficient measured is average value, and the infiltration coefficient of single layer can not obtain；2)
Geotextiles can only arrange one layer, and cloth is postponed and can not be replaced, after can not carrying out same solution different time effect
Silting comparative experiments；3) water level control is relatively easy, can not carry out water level lifting and reduce circulation experiment, after analyzing ringing
The infiltration coefficient of filler and the infiltration coefficient of geotextiles are tested；4) in experimentation, some equipment are provided with pressure monitoring
Equipment, sample position is arranged in few side walls, therefore can not sample during the experiment, analyzes initial soln after different time
The variation of ingredient and concentration.
