Background technology
Relative compaction experiment is a very important experiment of cohesiveless soil, its maximum dry density measuring method
For vibration hammer striking.Existing vibration compaction test apparatus is mainly made up of parts such as compaction cylinder, hammer and sleeves.This instrument
Device is when compaction test, and the grogs often having particle diameter less is clamp-oned in the gap of sleeve and compaction cylinder, causes test knot
During bundle, sleeve is difficult to extract, and can surprisingly pour out the soil sample after part is hit in fact the most when extracted, cause the failure of an experiment.
Additionally, need to keep vertically hammer guide rod during hitting in fact, but owing to simultaneously need to use vibrating tine, grasping
Author tends not to the most well hold vertical position.Based on above-mentioned both sides defect, the present invention proposes one
Plant novel cohesiveless soil maximum dry density tester.
Utility model content
The purpose of this utility model is to provide novel sandy soil that a kind of success of the test rate easy and simple to handle, real is high
Big dry density tester.
For achieving the above object, novel sand maximum dry density tester of the present utility model includes sleeve, hits reality
Cylinder, hammer, fixed support and base, wherein, described sleeve is installed on the upper end of described compaction cylinder；Described hit
Real cylinder is installed on described base；Described fixed support is made up of hammer fixed mount and annulus, and described hammer is fixed
Frame is fixed on base, the top being arranged at described hammer fixed mount of described annulus；Described hammer is by phase successively
Hammer bar even, dropping hammer and hammer seat composition into shape, described hammer bar is provided with alignment pin, described hammer is arranged at institute
Stating in compaction cylinder, described hammer bar passes described support bracket fastened annulus.
Wherein, described sleeve is a steel cylinder, and the inner surface of described steel cylinder lower end is provided with female thread,
Preferably, the height of female thread is about 3cm, and the upper end of described compaction cylinder is provided with and described steel cylinder
External screw thread corresponding to female thread, described sleeve is threaded by the external screw thread on female thread and compaction cylinder surface.
Described hammer fixed mount includes two relative steel rod members, and described steel rod member exceeds sleeve 8～12cm,
Two steel rod members and cross in centre to the other side's 90-degree bent at top.
Described compaction cylinder is a volume 250cm3Cylindrical drum, internal diameter is 5cm.
The diameter of described hammer bar is less than the diameter of annulus, and height is higher than described hammer fixed mount.
The diameter of described base is more than compaction cylinder external diameter, and there is a depression at its center for placing described compaction cylinder.
Described hammer weight 1.25kg, diameter 5cm, hammers high 15cm into shape.
Described alignment pin is positioned at the top 15cm that drops hammer.
Beneficial effect: compared with prior art, maximum dry density tester simple in construction of the present utility model, can
With the most fixing hammer bar so that it is keep in mechanism vertically, grogs can be avoided to clamp-on sleeve simultaneously
With in compaction cylinder gap, sleeve difficulty is caused to be extracted.

Detailed description of the invention
Below this utility model is further described.Following example are only used for clearly illustrating this practicality
Novel technical scheme, and protection domain of the present utility model can not be limited with this.
As shown in Fig. 1～Fig. 6, present embodiments provide a kind of novel sand maximum dry density tester, including
Sleeve, compaction cylinder 3, fixed support, base 10 and hammer.Wherein, sleeve is steel cylinder 1, is used to
Being arranged on compaction cylinder 3, the inner surface of its underpart has the female thread 2 of high 3cm.Compaction cylinder 3 is a volume
For 250cm3Cylindrical drum, its internal diameter is 5cm, and its outer surface has the high 3cm corresponding with internal thread of sleeve 2
External screw thread, can be integral with sleeve combination, compaction cylinder 3 bottom load base 10.Fixed support is by hitting
Hammer fixed mount 4 and annulus 5 form, and hammer fixed mount 4 is two the relative steel up stretched out by base 10
Rod member processed, rod member exceeds sleeve about 10cm, at top to the other side 90 degree bending, crosses in centre, forms one
Individual steelframe, has the annulus 5 of internal diameter an about 1cm in steelframe center.Base 10 is a circular thick bloom,
Diameter is slightly larger than compaction cylinder external diameter, has a circular depressed between two parties, just can put into compaction cylinder 3.During use
Fix with compaction cylinder 3 and fixed support and be connected.Hammer by hammer bar 6, drop hammer 7, hammer seat 8 and alignment pin 9
Composition, described hammer bar 6 is the steel rod member that a diameter is slightly less than 1cm, is positioned in compaction cylinder 3,
Its height slightly above hammer fixed mount 4.Hammer 7 weight 1.25kg, diameter 5cm, hammer high 15cm into shape；Hammer seat 8
It it is a diameter circular steel hassock sheet that is slightly smaller than compaction cylinder 3 internal diameter；Alignment pin 9 is on hammer bar 6
One projection, is positioned at the top 15cm that drops hammer.
In experimentation, hammer bar 6 upper end through hammer fixed mount 4 and is mentioned, compaction cylinder 3 is fixed
In base 10, check hammer fixed mount 4, it is ensured that hammer fixed mount 4 is positioned at the surface of compaction cylinder, set
Cylinder and steady pin hit the fixing height of drop of reality and 15cm for three layers realized in specification.Toward compaction cylinder 3
In insert soil sample, steadily put down hammer, test.Due to this utility model use screw thread riveting, can in case
Only fine soil grain enters among the crack of sleeve and compaction cylinder.
The above is only preferred implementation of the present utility model, it is noted that general for the art
For logical technical staff, on the premise of without departing from this utility model know-why, it is also possible to make some improvement
