Problems solved by technology

[0002] At present, in road construction projects, it is necessary to compact pavement material samples into various test pieces in order to analyze the characteristics of pavement materials. In order to better simulate the compaction effect of wheels on the road surface during the compaction process, it is necessary to use The gyratory compactor compacts the test piece while rotating. For example, the Chinese invention patent with the authorized announcement number CN250104Y discloses a gyratory compactor for compacting a material test piece, which is the same as the existing gyratory compactor.

Abstract

The rotary compacting instrument includes frame, bottom plate, top plate, elevating oil cylinder on the bottom plate, fixed testing drum with backup board connected to the output shaft of the elevating oil cylinder, compacting oil cylinder on the backup board, pressing head in the upper part of the frame, pressing head oil cylinder on the top plate, pressing disc fixed to the output shaft of the pressing head oil cylinder, and downward extending pressing rod in the lower part of the pressing disc, with the top plate having hole corresponding to the pressing rod. The present invention has rotary compacting to simulate the practical condition for wheel to roll the road surface and can obtain practical experiment data.

Description

technical field [0001] The invention relates to a rotary compactor used for preparing test pieces in road construction projects such as highways. Background technique [0002] At present, in road construction projects, it is necessary to compact pavement material samples into various test pieces in order to analyze the characteristics of pavement materials. In order to better simulate the compaction effect of wheels on the road surface during the compaction process, it is necessary to use The gyratory compactor compacts the test piece while rotating. For example, the Chinese invention patent with the authorized announcement number CN250104Y discloses a gyratory compactor for compacting a material test piece, which is the same as the existing gyratory compactor. , the indenter remains horizontal during the compaction process, while the test piece is inclined at a certain angle with the test cylinder relative to the lower end surface of the indenter and performs rotary motion ...
