Roadbed soil dynamic resilience modulus testing device
The invention relates to the technical field of road construction, and discloses a roadbed soil dynamic resilience modulus testing device which comprises an outer frame, a material gathering hopper arranged in the outer frame and a sample preparation mechanism arranged below the material gathering hopper. The material collecting hopper is in a conical hopper shape with a wide upper part and a narrow lower part; the bottom of the material collecting hopper is a circular discharge pipe orifice; and a valve unit is arranged at the bottom of the discharge pipe orifice. The sample preparation mechanism comprises a sample preparation cylinder arranged under the discharging pipe opening and a quantitative transfer unit located between the sample preparation cylinder and the discharging pipe opening, and the quantitative transfer unit is used for receiving a certain amount of materials and transferring the materials into the sample preparation cylinder. Through the structure, materials can be automatically added into the sample preparation cylinder, and the materials can be conveniently and gradually compacted layer by layer in the sample preparation cylinder, so that the density of a sample is more uniform, and the dynamic resilience modulus test result of roadbed soil is more accurate.
本发明涉及道路建设技术领域，公开了本发明提出的路基土动回弹模量试验装置，包括外框架、设于外框架内的聚料斗以及设于聚料斗下方的试样制备机构。聚料斗为上宽下窄的锥形斗状，聚料斗的底部为圆形的出料管口；出料管口的底部设置有阀门单元。试样制备机构包括设于出料管口正下方的试样制备筒、位于试样制备筒和出料管口之间的定量转移单元，且定量转移单元用于接收一定量的物料并转移至试样制备筒中。本发明通过上述结构，能够自动化的向试样制备筒内添加物料，方便在试样制备筒内逐次逐层压实物料，从而使得试样的密度更加均匀，使得路基土动回弹模量试验结果更加准确。
