Набор конусов для песка

A pit of known volume is excavated, and the removed soil is weighed to determine its moisture content and dry density. The same pit is then filled with calibrated dry sand. By comparing the amount of sand required to fill the pit with the pit volume, the in-situ unit weight of the soil is calculated. This method provides a direct assessment of field compaction degree and allows comparison with laboratory results. Sand Cone Set consists of a metal cone, plastic sand-filling container, calibration can, steel base plate, and hole-cutting accessories. The valve system located at the lower end of the cone ensures controlled and uniform flow of sand into the pit. The calibration container is used to verify equipment accuracy before testing. The steel base plate stabilizes the edges of the test pit during the procedure, helping maintain compliance with testing standards. Its portable and compact design allows easy field use. Simple test procedure can be performed by a single operator, offering practical on-site evaluation.
