Sand Cone Test

O: 5/XI-3/GTK/10

Objective
Determine the density of the soil layer by measuring the volume of holes directly.
 
Equipment

1. Sand cone
2. Bottle sand cone
3. Field Plate
4. Standard Sand
5. Chisel
6. Rubber hammer
7. Brick Trowel
8. Tin

Procedure

1. Fill the bottle with standard sand.
2. Weigh the bottle and cone, following graded sand that has been filled sufficiently.
3. Clean the surface soil to be excavated and averaged.
4. Place the plate in the soil surface in a solid position.
5. Dig a round hole in accordance with the diameter of the hole plate with a chisel, a hammer and a brick trowel.
6. Weigh the cans that have been cleared to be empty (W-9).
7. Enter all the soil excavation results in the field can then weigh the weight (W-8).
8. Place the sand cone which already contains the sand over the field plate earlier.
9. Close the tap cone, after the sand stops flowing,
10. Take some soil around the test is to check their water content.
11. Weigh the sand cone containing the remaining sand in it.
12. Calculate the weight of sand that came out of the bottle.
13. Take back the clean sand that fills the hole had to be used in subsequent experiments.

Calibration Equipment

1. Weigh a cone and an empty bottle (W-1).
2. Enter the sand into the bottle through a cone and then weighed (W-4).
3. Place the ground plate on a clean glass surface and attach the cone following last bottle on it.
4. Open the tap so that the sand will fill the cone below the funnel.
5. Close the tap cone, after the sand stops flowing.
6. Weigh the sand cone containing the remaining sand in it (W-5).
7. Calculate the weight of sand that fills the cone bottom.
8. Repeat this procedure 3 times and the results are averaged.
9. The difference between the results of each experiment should not be more than 1%.
10. Enter the sand into the bottle through a cone until full (let the sand fall freely), then weigh the following funnel (W-3), repeat 3 times in a row. take the average price, the difference between the weight of each with the average value should be no more than 1%.
11. Measure volume by filling bottles with water until full.
12. Weigh heavy cone and a bottle filled with water (W-2).  
13. Repeat the procedure 10 s / d 12 2 twice.

Maintenance

1. Lubricate valve mouthpiece regularly with oil to prevent rust / jam.
2. Drying sand gradation when it is damp / sticky
