Technical Field
The utility model belongs to the technical field of the tight dress density test of thin gathering of materials, a tight dress density jolt ramming device of thin gathering of materials is specifically disclosed.
Background
The tight packing density test of the fine aggregate is to determine the tightness degree of sand in a natural state, the void ratio of the sand can be calculated through the apparent density of the sand, the void ratio is the proportion of the void volume among the sand particles to the total volume, and the void ratio reflects the compactness degree of the mutual filling of the particles of the material, so if the void ratio of the sand is accurately determined, the tight packing density test of the sand must be done, after each layer of sample is packed, a compaction rod (generally a reinforcing steel bar with the diameter of 10 mm) needs to be arranged at the bottom of a capacity cylinder to carry out bumping, however, the reinforcing steel bar always moves continuously in the bumping process, great trouble is brought to the operation, meanwhile, the bumping effect is also influenced, and the accuracy of the experimental result is further influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a fine aggregate tightly adorns density plain bumper device to improve the fine aggregate and tightly adorn the unstable problem of plain bumper of putting of density test in-process capacity section of thick bamboo heelpiece, improve the accuracy of experiment.
In order to achieve the purpose, the utility model provides a fine aggregate compact density jolt ramming device, which comprises a base and a jolt ramming bracket; four limiting grooves which are distributed in a cross shape are arranged on the base; the tap support comprises a tap rod with the diameter of 10mm, a limiting ring arranged above the tap rod and a connecting rod for connecting the tap rod and the limiting ring; the tap rod is arranged in the two limiting grooves which are oppositely arranged; the quantity of connecting rod is two, sets up respectively at the both ends of the diameter of spacing ring.
Furthermore, the tap rod is provided with a raised stop block on the rod body outside the limit groove.
Further, the stopper is an annular stopper.
Further, the base is a square base; the four limiting grooves are respectively arranged on the middle points of the edges of the base.
Furthermore, the limiting groove is a gap between two limiting rods fixed on the base.
Further, the base and the tap support are both made of stainless steel materials; the limiting rod is welded on the base.
Compared with the prior art, the utility model discloses following beneficial effect has:
when the fine aggregate compact density test is carried out, the compaction support is arranged in the limiting groove, 1 part of the sample is taken, and the sample is arranged in the volumetric cylinder in two layers. After the first layer is filled, the volumetric cylinder is placed into a limiting ring of the tap support, the volumetric cylinder is pressed, the volumetric cylinder is alternately knocked down for 25 times from left to right, then the volumetric cylinder is taken down and filled into a second layer of sample, the tap support is taken down and rotated for 90 degrees and then filled into a limiting groove, the volumetric cylinder is placed into the limiting ring, the volumetric cylinder is continuously alternately knocked down for 25 times from left to right, the volumetric cylinder is taken out, redundant samples are scraped flat along the central line of the cylinder opening in two opposite directions, and the quality of the samples is weighed. The utility model provides a fine aggregate tight packing density plain bumper because the plain bumper passes through the connecting rod and links into an organic whole with the spacing ring, and the plain bumper places in the spacing groove, puts into the capacity section of thick bamboo behind the spacing intra-annular begins to top, and the plain bumper can not roll, has guaranteed to top the effect, and simple manufacture, and the consumptive material is few.
