Description

Technical Field

[0001] The utility model relates to the technical field of sand filling cylinders, in particular to a sand filling cylinder which is convenient for measuring and used for roadbed detection. Background Art

[0002] Compaction is one of the key indicators for roadbed and pavement construction quality inspection, and is also one of the main control items for roadbed and pavement construction quality inspection. It characterizes the compaction condition after on-site compaction. The higher the compaction, the greater the density, and the better the overall performance of the material. Compaction is also called compaction coefficient. For roadbed and pavement base: compaction refers to the ratio of the dry density actually achieved on site to the maximum dry density obtained by the indoor standard compaction test, expressed as a percentage. For asphalt pavement, the ratio of the density actually achieved on site to the standard density is expressed as a percentage. The sand filling cylinder is a soil density measuring device. Especially in the process of highway construction, the compaction quality of roadbed filling materials, pavement subbase or base paving layer materials, and gravel pavement needs to be evaluated on site through on-site testing of the density after rolling in accordance with the "Highway Engineering Quality Inspection and Evaluation Standards". For the density experiment of fine-grained soil, sandy soil and gravel soil with a maximum particle size not exceeding 31.5 mm, the sand filling method is usually used for detection.
