Water level in collecting pipe judges the expansion rate of concrete, easy to operate；
2. cavity is formed respectively on the utility model surrounding and top in test box, sponge is respectively provided with cavity, can be at the same time
Detect the degrees of expansion of concrete in all directions, accuracy of detection higher.
Further, it is provided with circular bubble in the rack.Circular bubble is used for the process in the test of concrete expansion rate
Middle convenience observes whether the test box is in formation state, and test is proved when the center bubble of the circular bubble is located at middle
Case is located at formation state, otherwise, it is necessary to adjust the position of test box.
Further, the collector pipe is transparent pipe.Transparent collector pipe is easy to the water level in observation collector pipe.
Further, it is provided with scale on the tube wall that catchments.Catchmenting, scale is set on tube wall, can be more directly perceived
With the water level in accurate observation collector pipe.
Further, the top board undersurface is provided with cover film.Cover film is used to seal and isolate mixed in placed cavity
Solidifying soil, avoids external environment from influencing testing result.
Further, the cover film is plastic film.The leakproofness of plastic film is preferable, can be preferably by concrete
It is isolated from the outside.
Further, the thickness of the cover film is 10mm.So that the better tightness of cover film.
Brief description of the drawings
Fig. 1 is a kind of schematic diagram of concrete expansion rate detection device embodiment of the utility model.
Embodiment
The utility model is described in further detail below by embodiment：
Reference numeral in Figure of description includes：Rack 1, test box 2, placed cavity 21, cavity 22, side plate 3, top plate
31st, sponge 32, water pipe 4, collector pipe 41, circular bubble 5.
Embodiment is substantially as shown in Figure 1：
A kind of concrete expansion rate detection device of the utility model, including rack 1, are placed with test box 2 in rack 1, survey
Examination 2 inside top of case slidably connects top plate 31, and cavity 22, top plate 31 are formed between top plate 31 and the inner wall at the top of test box 2
Bottom surface is covered with the plastic film that thickness is 10mm；Side plate 3 is all around slidably fitted with test box 2, is shown in figure
Two blocks of left and right side plate 3, is connected with waterproof cloth between adjacent two blocks of side plates 3；Formed between 2 or so inner wall of side plate 3 and test box empty
Chamber 22, forms the placed cavity 21 for being used for holding concrete between side plate 3 and top plate 31.
Sponge 32 is provided with cavity 22, as shown in Figure 1, the quantity of sponge 32 is 3, and 32 both ends of sponge of top are fixed
It is connected between 2 inner wall of top plate 31 and test box, two pieces of 32 both ends of sponge in left and right cavity 22 are fixedly connected on side plate 3 and survey
Between examination 2 inner wall of case.The cavity 22 of top and the cavity 22 of left and right are communicated with water pipe 4, test in the rack 1 of lower section and are provided with
The graduated collector pipe 41 of transparent band, the water pipe 4 are connected with collector pipe 41.Circle is installed in the rack 1 in the left side of test box 2
Spirit level 5.
During using the utility model, the slurry of the concrete sample stirred evenly is slowly injected into placed cavity 21, is loaded
The slurry top surface of concrete sample offset with top plate 31, wait Concrete in Natural cooling.Plastic film is used to seal and completely cut off
