Description
Technical field
The utility model belongs to test mould processing and manufacturing technology, is more particularly to surveyed for engineering material mechanics performance
A kind of chance water response type grouting material cylinder test specimen molding machine of examination.
Background technology
Polyurethane grouting material is polyurethane（Coating, adhesive, fluid sealant etc.）One of kind of material, since it has
Be swift in response, cured product performance adjustability is strong, meets the fast reaction of water energy and the physical and mechanical property for making volume expansion etc. excellent,
The fields such as distress in concrete water blockoff, curtain antiseepage, underground engineering pre-grouting, foundation stabilization are largely used to, having become should
With one of most commonly used chemical grouting material.
Polyurethane grouting material be the performed polymer prepared using polyisocyanates and more alkyl compound polymerisations as host agent,
By injection basis or the structure of being in the milk, the generation slurries material with certain elasticity or intensity induration not soluble in water is reacted with water
Material.In the grouting system of relative closure, carbon dioxide gas that polyurethane grouting material reaction is released know from experience generate it is very big interior
Pressure pushes slurries to penetrate into diffusion to the hole of unconsolidated formation, crack, cellular structure or crack is made to be filled out completely by slurries
It fills.Slurry dilatancy is restricted bigger, and the induration formed is closer, and impermeability and compressive strength are higher.Also, its with
Concrete crack surface and soil, mineral grain have stronger bonding force, the effects that playing water blockoff and improve foundation strength.
《Polyurethane grouting material》In JC/T2041-2010, for test polyurethane grouting material water-swellable rate and
The die trial of the cylinder test specimen of compression strength to be made of metal tube of the band there are two capping.It is main existing for discovery during experiment
Problem is wanted to include：（1）It is demoulded after sample molding difficult.With not with the interleaving agent of specimen reaction（Such as Organosilicon Release Agent）It is applied to examination
Mould inner wall and capping inner wall are ineffective, and reduction form removal difficulty, especially polyurethane-cement, polyurethane-waterglass are compound
When grouting generates hard induration.Reason is the carbon dioxide gas that polyurethane grouting material reaction releases under closed environment
Very big interior pressure can be generated, mould inner surface can be attached on securely after grout curing, easily stick to one with metal tube；
（2）Capping is difficult.Polyurethane grouting material is swift in response, and the most fast several seconds can react, even if by slurries and water cooling,
It also is difficult to cover before foaming, the slurries that lid is often foamed during experiment squeeze out, and test material preparation is caused to fail.（3）Opening is difficult
Degree is very big.Since induration is combined closely, and die trial size is small with die trial after grout curing, it is big to clamp difficulty, and when opening is easy
Stripped thread, capping are easily jumped out and are hurted sb.'s feelings.（4）Test specimen integrality is poor.Since molding induration hardness is big, when demoulding, need to be by ingot stripper
Test specimen is ejected, easily causes test specimen or mold damaged, is scrapped so as to cause sample preparation failure or mold.Therefore for accurate science into
Row polyurethane grouting material water-swellable rate and compressive strength test design the molding die of a set of science practicality, have important
Economic implications.
