Sand face on, jar block is mentioned to top end of sliding rod, it is then allowed to slide naturally to baffle ring, repeat jar block slide process 5 times,
Complete first time back-up sand pressure compacting；Then first time back-up sand compacting process is repeated, until fill out sand tube is filled up.
An other fill out sand tube is changed, repeats the back-up sand process of first fill out sand tube completely.Since the quality of jar block is certain,
The landing height of jar block is fixed, and the jarring number of jar block is certain, and every time plus the amount of sand is fixed, therefore jar block is to sand core
Compaction is constant, it is possible to guarantee that the sand core permeability that loads twice is identical or substantially close to can satisfy parallel test
Demand.
Embodiment 2:
Loading a root long degree is 35 centimetres, the fill out sand tube that internal diameter is 3.8 centimetres.
Choose two scale bars that length is 20 centimetres, the pressure head that outer diameter is 3.8 centimetres, referring to Fig.1 by T-type handle, cunning
Bar, jar block, (outer diameter is for baffle ring, scale bar (length is that 20 centimetres of two scale bars are also connected with baffle ring) and pressure head
3.8 centimetres) it connects.Back-up sand and debulking methods are with embodiment 1, until fill out sand tube is filled up.
Embodiment 3:
Loading a root long degree is 15 centimetres, the fill out sand tube that internal diameter is 2.5 centimetres, and sand core requires to be divided into have obvious permeability poor
Different three sections, three segment length are respectively 3 centimetres, 5 centimetres, 7 centimetres.
Choosing length is 20 centimetres of scale bar, the pressure head that outer diameter is 2.5 centimetres, referring to Fig.1 will by T-type handle, slide bar,
Jar block, baffle ring, scale bar (length is 200 centimetres) and pressure head (outer diameter is 2.5 centimetres) connect.
When back-up sand, the combined type sand-filling apparatus connected is put into empty fill out sand tube first, from the upper surface of fill out sand tube
The reading L1 on scale bar is read in place's head-up, then in fill out sand tube plus mesh number be M1 (mesh number M1 is a range value, such as 20
Mesh~40 mesh) sand, back-up sand and debulking methods all notice that head-up reads scale bar in back-up sand with embodiment 1, every time after compacting
The reading L2 of pipe upper end surface, until | L2-L1 |=3 centimetres, complete first segment back-up sand；Then, changing another mesh number is M2
The sand of (mesh number M2 is a range value, such as 80 mesh~100 mesh) continues back-up sand, is compacted with sand-filling apparatus, and look squarely reading
Scale bar fill out sand tube upper end surface reading L3, until | L3-L2 |=5 centimetres, complete second segment back-up sand；Then changing mesh number is
The sand of M3 (mesh number M3 is a range value, such as 180 mesh~200 mesh) continues the back-up sand of third section, and looks squarely reading scale
Bar fill out sand tube upper end surface reading L4, until | L4-L3 |=7 centimetres, complete the back-up sand of third section.So far entire fill out sand tube
Back-up sand is completed.
Its internal cores of the fill out sand tube loaded in this way are just divided into three sections that permeability has notable difference, can be used to simulation layer
Between heterogeneity.
