The invention belongs to the gypsum mould field, relate to calcium plaster preparation aggregation.

Background technology

In the prior art

In gypsum mould, especially the gypsum mould of the on-site tridimensional footprint in the public security work extracts, and is the scene preparation calcium plaster of traditional type always; Land plaster, water are placed the stirring basin, after stirring evenly with stirring rod, be filled in the footprint frame, extract after the gypsum sets, weak point is that it is more to carry instrument, and process for preparation is loaded down with trivial details, speed is slow; Do not possess auxiliary measurers such as balance, graduated cylinder in view of the scene, therefore, be difficult to guarantee the accurate ratio of land plaster and water, because the improper perfusion failure that causes of calcium plaster preparation also just is difficult to avoid, even can stir in the basin and can't pour into because of the calcium plaster overrich is set in, simultaneously, affected by environment bigger during the preparation calcium plaster, the particularly influence of wind; The amount of preparing calcium plaster in addition also is difficult to be fit to the perfusion aequum, in most cases is that calcium plaster is superfluous and cause waste, and instrument all need clean after preparation was finished, and has not only wasted water but also contaminated environment; Also have, can produce bubble in the calcium plaster process for preparation, and the concentrated upper strata that hangs, swims in calcium plaster, the scene preparation calcium plaster of traditional type is filled in the footprint frame, the upper strata calcium plaster can carry bubble and be introduced in the footprint frame and contact with vestige, go out or ooze out and break and entrained bubble is can not be all contrary timely, thereby influence the vestige quality with liquid; There is the gypsum footprint to extract case in the market, land plaster storage box, gypsum spoon, gypsum stirring box and stirring rod are housed in the aluminum alloy frame out of frame box, also have plastics footprint frame, it just gives the formulation tool of calcium plaster to concentrate to converge, be easy to carry, fundamentally do not address the above problem.

Summary of the invention

The technical problem that solves:

Calcium plaster preparation aggregation is provided, can overcome the deficiencies in the prior art, make that on-the-spot preparation calcium plaster is convenient, simple, speed is fast, efficient is high, water and land plaster accurate in scale, consumption is fit to, and is not affected by environment, and calcium plaster can guarantee the vestige quality when being filled in the footprint frame, both saved material, be beneficial to environment again, also be suitable for the soil property type that is suitable for the vestige place.

The technical scheme that adopts:

Calcium plaster preparation aggregation has water, land plaster and apparatus for placing thereof, and it is characterized in that: the quality sum of water, land plaster is the required quality settings value of calcium plaster to be prepared, and the ratio of water and land plaster is the required ratio setting value of calcium plaster to be prepared; Being contained in the inner bag that soft plastic material makes of described water-stop, containing the inner bag of water and the common sealing of described land plaster be contained in that soft material is made and tensile strength is higher than in the outer bag of inner bag.

Beneficial effect:

Calcium plaster preparation aggregation, because in, outer bag is soft material and makes, the tensile strength of outer bag is higher than inner bag, and the water in the inner bag easily flows, the inner bag pressurized is outer account easily, and enough outer account spaces are arranged, therefore, during application, externally bag applies the enough big again external force of appropriateness, described external force must act on inner bag, tear as hand, or pin is stepped on, inner bag is broken and sluice and dissolve in the land plaster, but outer bag must be able to not break, and afterwards, holds multidirectional the tossing about of outer bag and rocks, after making in the outer bag water and land plaster fully mixing, the calcium plaster preparation is promptly finished, and then, the bottom of outer bag is cut off the gap of an appropriateness, portable outer bag and down with gap, can smoothly the calcium plaster for preparing in the outer bag be filled in the footprint frame by gap, therefore, the present invention makes the method for on-the-spot preparation calcium plaster be different from traditional type fully, because in, in the outer bag water is housed respectively, the quality sum of land plaster and the ratio of water and land plaster are respectively the ratio setting value of the required quality of calcium plaster to be prepared and water and land plaster, therefore, the calcium plaster that makes of calcium plaster preparation aggregation is accurate in scale, consumption is fit to, and the soil property type at suitable vestige place; Owing to fundamentally broken away from the method for the on-the-spot preparation of traditional type calcium plaster, need not numerous instruments such as stirring rod, stirring box, also need not artificial stirring, cleaning means etc., therefore, make that on-the-spot preparation calcium plaster is convenient, simple, speed is fast, efficient is high, not affected by environment again, not only save material but also be beneficial to the protection environment; During perfusion, because portable outer bag of energy and gap are operated downwards, the bubble that produces in the calcium plaster process for preparation is concentrated the upper strata that hangs, swims in calcium plaster, bubble-free bottom gypsum slurry injects the footprint frame earlier and contacts with vestige, vestige is formed initial protective layer, when the upper strata calcium plaster injected subsequently, both portable band bubble can not influence the vestige quality yet; Simultaneously, easily make, cost is low, conveniently deposits and carries, the gypsum mould that is particularly useful for the on-site tridimensional footprint in the public security work extracts.
