Description
Technical field
The invention belongs to high-level waste geological disposal padded coaming experimental study field, and in particular to one kind considers swollen
Moisten 1/8 fan-shaped soil block compacting tool set of native spring-back effect.
Background technology
Using multibarrier, (geologic medium belongs to the natural cover for defense to the high radioactivity nuclear waste plan in China, and waste body, packaging are held
Device is gentle to be rushed backfilling material etc. and belongs to engineering barrier) mode of deep geological disposal is disposed.Padded coaming is as in disposal storehouse
The important component of multibarrier system, it is last road artificial barrier being filled between dedicated waste tanks and geologic body, plays
The important function such as engineering barrier, hydraulics barrier, chemical barrier, conduction and lost radwaste decay heat, are geological disposals
The effective guarantee of storehouse safety and stability.By research both at home and abroad in recent years, the bentonite using montmorillonite as main component
It is considered as the most suitable buffering backfilling material of high level radioactive waste repository.
In fender long-term behaviour research, the preparation of padded coaming high-pressure solid bentonite block mainly employs static pressure
Real and power hits real two ways.The interior carried out for countries in the world and the research work of the large-scale stand of field test, are adopted
With buffering backfilling material blockwork, and for the preparation of blockwork, the mode for employing Static compaction prepares full chi
Very little or portion size building block.Meanwhile high-pressure solid bentonite is after compacting terminates, because difference occurs in the swelling properties of itself
The rebound phenomenon of degree, therefore at the beginning of mold design, it is necessary to consider the spring-back effect of bentonite in lump.Compacting tool set be prepare it is slow
The indispensable instrument of material building block is rushed, therefore designs and builds that simple in construction, consolidation is easy to operate, is adapted to high-volume raw
The compacting tool set of production has important practical value.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of 1/8 fan-shaped soil block pressing die for considering bentonite spring-back effect
Tool, the Mould operation are convenient, and using simple, compacting block is uniform, is adapted to produce in enormous quantities.
In order to solve the above technical problems, a kind of 1/8 fan-shaped soil block compacting tool set for considering bentonite spring-back effect of the present invention,
The mould includes punch-pin, cavity plate and backing plate；There is fan-shaped pylone in the middle part of the cavity plate；The punch-pin is sector, in the middle part of cavity plate
Fan-shaped pylone coincide；The backing plate is padded on punch-pin, cavity plate bottom, between the cavity plate sector angle is 44 °~44.5 °.
The cavity plate sector inside radius is more than inside radius 2mm~4mm of 1/8 fan-shaped bentonite in lump, and outer radius is less than 1/8 fan
Outer radius 2mm~4mm of shape bentonite in lump.
The height of plan compacting soil block of the height of the cavity plate more than 2~3 times.
Male Die Size is less than the scalloped recess size of cavity plate, and clearance between punch and die is less than 0.1mm~0.2mm after matched moulds.
The punch-pin, cavity plate and backing plate use 1Cr18Ni9Ti or 4Cr13 materials.
The length and width of backing plate is greater than cavity plate.
The advantageous effects of the present invention are：
(1) the 1/8 fan-shaped soil block compacting tool set of the present invention for considering bentonite spring-back effect, it is contemplated that compacting swelling
Resilience after soil block mould unloading, angle reduce 0.5 °~1 °, and inside radius increase, outer radius reduces, and ensures the fan-shaped soil block being pressed into
Annulus can be combined into.
(2) the mold material anticorrosive property is good, and the part contacted with bentonite is heat-treated, and to finish and
Hardness clearly requires, and can improve service life.
(3) after cavity plate and punch-pin matched moulds, gap is small, can effectively ensure that sample pressed density is uniform, occurs without scattered side and falls
Angle phenomenon, sample formation are preferable.
