Abstract
The utility model discloses a cohesionless soil maximum dry density measurement instrument. The measurement instrument comprises a base, a round cylinder, a vibrating fork and a hammer, wherein the round cylinder is made of a transparent material; scale marks are formed on the inner sidewall or the outer sidewall of the round cylinder from bottom to top; and the round cylinder is in threaded connection with the base. The cohesionless soil maximum dry density measurement instrument provided by the utility model overcomes the disadvantage that the base and the round cylinder in the prior art are easily separated due to adoption of snap-fit connection, so that test sample sand overflows from the bottom to influence the accuracy of the measurement result. The improved cohesionless soil maximum dry density measurement instrument can strictly control the change in volume of the sample sands when conducting the maximum dry density measurement by a vibration and hammering method; and the round cylinder containing the sample sand is made of the transparent material, and has scale marks, so that a tester and a researcher can effectively control the maximum dry density time of the test sample on each layer.
Description
Technical field
The utility model relates to a kind of non-cohesive soil maximum dry density analyzer.
Background technology
At present, more and more for the discussion of non-cohesive soil and research at home the research institutions and academic research, and along with the deepening continuously of scientific research, also more and more higher to the accuracy requirement of test.When adopting the vibration hammer striking to carry out the maximum dry density test, " Standard for test methods of earthworks " requires to stop hammering when every layer constancy of volume, yet existing gravimetry instrument does not have visual mark post for constancy of volume, causes laboratory technician and scientific research personnel big to number of times and the time assurance difficulty of hammering; In addition, when using hammering method to do the minimum dry density test, adopt card to join between cylinder base and the cylinder and be connected, base separates with cylinder under the effect of knocking of vibration hammer easily, make the test sand sample overflow from the bottom easily, influenced accuracy of experimental results.
The utility model content
The purpose of the utility model embodiment is to propose a kind of non-cohesive soil maximum dry density analyzer, can effectively solve above-mentioned technical matters of the prior art.
To achieve these goals, the utility model adopts following technical scheme:
A kind of non-cohesive soil maximum dry density analyzer, comprise base, circular cylinder body, vibrating tine and hammer, described circular cylinder body is made for the transparence material, and from bottom to top mark has the scale lines on the madial wall of circular cylinder body or lateral wall, adopts between circular cylinder body and the base to be threaded.
The utility model has the advantages that:
In the utility model, adopt between base and the circular cylinder body and be threaded, overcome and adopted card to join when being connected in the prior art between the base and circular cylinder body to occur easily separating, the test sand sample overflows and then influences the deficiency of test findings accuracy from the bottom, through the non-cohesive soil maximum dry density measuring instrument after improving, can guarantee the variation of strict control sand sample volume when using the vibration hammer striking to carry out the maximum dry density test; In addition, the circular cylinder body that is loaded with sand sample adopts transparent material to make, and is marked with the scale lines at the circular cylinder body subscript, makes laboratory technician and scientific research personnel to control effectively to the maximum dry density time of every layer of sample.
Description of drawings
Fig. 1 is the structural representation of a kind of non-cohesive soil maximum dry density analyzer among the utility model embodiment;
Fig. 2 is the front view of base among Fig. 1.
Embodiment
In conjunction with Fig. 1, shown in Figure 2, a kind of non-cohesive soil maximum dry density analyzer, comprise base 1, circular cylinder body 2, vibrating tine 3 and hammer 4, circular cylinder body is made for the transparence material, from bottom to top mark has scale lines 5 on the madial wall of circular cylinder body or lateral wall, the scale lines are horizontally disposed with, and are parallel with the upper edge of hammer 4 to guarantee, adopt between circular cylinder body 2 and the base 1 to be threaded.
During use, earlier that circular cylinder body 2 lower ends and the base 1 of maximum dry density analyzer in the utility model is closely fixing by screw thread, pour the test sand sample into toward circular cylinder body inside, / 3rd places of a little higher than circular cylinder body volume, test with the vibration hammer striking again, can observe the scale that marks on the hammer place circular cylinder body, when the scale of hammer place correspondence is constant, can be observed constancy of volume, the maximum dry density test of following one deck.
The utility model is simple, and is easy to assembly, for the operation of testing provides convenience, is beneficial to the raising accuracy of experimental results, has important practical application.
Certainly; more than explanation is not to restriction of the present utility model; the utility model also is not limited to above-mentioned giving an example; should be noted that; any those of ordinary skill in the art are under the instruction of this instructions; all that make are equal to replacement, obvious form of distortion, all drop within the essential scope of this instructions, ought to be subjected to protection of the present utility model.
