Description
Technical field
The utility model belongs to test unit processing and manufacturing and application, particularly for high polymer grouting test mould and the application thereof of a kind of simulated roadway reparation of engineering material mechanics Performance Detection.
Background technology
High polymer grouting technology is the foundation rapid reinforcement technology that 20 century 70s grow up.The characteristic that after utilizing high polymer material generation chemical reaction, rapid spatial expansion also solidifies, reaches consolidated subsoil, fills the object coming to nothing or promote floor.At present, the production of high polymer grouting material and range of application are expanding rapidly and are promoting, high polymer grouting technology plays more and more important effect in the development of national economy every field, be mainly used in foundation stabilization and the road maintenance of industry and covil construction, in the maintenance of subgrade and pavement Wicresoft with reparation, obtain good application especially in recent years.
The mould that high polymer grouting test adopts launches round industrial goods mostly, therefore also comparatively imperfect shop experiment mould, existing subject matter comprises:
One is that functional die is single; The high polymer grouting mould of current use is substantially all directly utilize traditional soil test mould, or on the basis of traditional soil test mould, carried out simple adjustment, the test specimen under shaping a kind of condition can only be used for or carry out some correlation tests in grouting test, slip casting effect when different gradation or different road surface thickness can not be simulated, function is too single, does not have applicability widely.
Two is that grouting hole sealing is poor; Very large bulging force can be produced in high polymer grouting process, after slip casting, if grouting hole blocking surface of contact that is not tight or mold component is poorly sealed, the problems such as slurry sprays can be caused outward, the life security of serious harm staff.
Three is test specimen demoulding difficulties; Because high polymer grouting material viscosity when foaming is comparatively large, bulging force is comparatively strong, and specimen molding rear surface is attached on mould inner surface, cause in knockout course test specimen or mould damaged, cause test specimen normally to use and scrap with mould.
Four is that pad pasting is not easy to operate; Consider that the viscosity of injecting paste material when foaming is comparatively large, thin film can be covered at mould inner surface in process of the test, both be convenient to the demoulding, and damage can not caused to test specimen when the demoulding again, ensure the complete of test specimen.But because current mould is the pad pasting carried out after assembled end, pad pasting work is not easy to operate, very easily on the corner produces to leak and paste or thin-film multilayer overlapping phenomenon, cause pad pasting in uneven thickness, error is caused to sample dimensions and causes test specimen layering.
Five is test specimen cutting errors; Directly cut obtained whole test specimen, what gained sample dimensions and regularity all can not be strict meets requirement of experiment, and surface of test piece integrality is poor, directly affects degree of accuracy and the science of test findings.
High polymer grouting technology obtains good application in every field, and effect is particularly outstanding.When wherein repairing for road surface, very high to the requirement of strength of material, the relation grasped between the strength character of high polymer grouting material and many factors is quite important.And mould is the necessity of the strength character test carrying out indoor material, the problem of mould directly affects the quality of shaping test piece, is one of core of test success or failure.Therefore, the design and selecting of mould all will be rigid in checking up.
ASSOCIATE STATISTICS shows, and in mechanical processing industry, the consumption value of annual mould is five times of various lathe total value.A large amount of consumption of mould, not only directly increase production cost, and cause a large amount of production line frequently to stop production because of frequent more mold exchange to cause larger economic loss.The consumption of mould is also fully demonstrated in the shop experiment of scientific research, a large amount of moulds is all scrapped because its local material damages, and the process-cycle of mould is long, processing charges is high, therefore, according to actual needs various mould is improved, to extend the mold use life-span, there is important economic implications.
