Static sounding autonomous penetration system based on bionics
The invention discloses a bionics-based static sounding autonomous penetration system which comprises a controller, an upper expansion device, a loading device, a lower expansion and contraction device and a static sounding probe, the upper expansion device comprises an elastic film surrounding the hollow cylinder with the water permeable holes; the loading device comprises four groups of hydraulic loading units; the lower expanding and contracting device comprises six metal blades capable of expanding and contracting in the radial direction. Water is filled into the elastic film so that the elastic film can expand and extrude surrounding soil, and counter force needed by stretching of the loading device is provided. The probe can vertically penetrate into a soil body and change the advancing direction by controlling four groups of hydraulic loading units in the loading device. When the metal blades are unfolded, the bearing force of the soil body above the metal blades provides the counter force required when the loading device is shortened. A counter-force device does not need to be arranged on the ground surface, and a probe rod does not need to be arranged between the loading device and the static sounding probe. The device has small disturbance to the surrounding environment, can be used in places where large machines are difficult to reach, and expands the application range of static sounding test sites.
本发明公开了一种基于仿生学的静力触探自主贯入系统，包括控制器、上部膨胀装置、加载装置、下部展缩装置和静力触探探头；上部膨胀装置包括包围带有透水孔的空心圆柱筒外的弹性膜；加载装置包括四组液压加载单元；下部展缩装置包括六个可径向展缩的金属叶片。通过向弹性膜内充水使其膨胀挤压周围土体，用于提供加载装置伸长时所需反力。通过控制加载装置中四组液压加载单元可使探头竖向贯入土体和改变前进方向。金属叶片展开时，其上方的土体承载力提供加载装置缩短时所需的反力。本发明无需在地表设置反力装置及在加载装置与静力触探探头之间设置探杆。本发明对周围环境扰动小，可用于大型机械难以到达的地点，拓展了静力触探试验场地适用范围。
