Combined variable-diameter single pile and combined variable-diameter single pile testing device
The invention provides a combined variable-diameter single pile and a combined variable-diameter single pile testing device, the combined variable-diameter single pile comprises a variable-diameter pile body, an upper pile body and a lower pile body, the variable-diameter pile body is of a conical cylinder structure with a wide upper part and a narrow lower part, and the outer diameter of an upper threaded opening of the variable-diameter pile body is larger than that of a lower threaded opening of the variable-diameter pile body; the upper threaded opening of the variable-diameter pile body is in threaded connection with the upper pile body; the lower threaded opening of the variable-diameter pile body is in threaded connection with the lower pile body, and the outer diameter of the lower pile body is smaller than that of the upper pile body. The combined type variable-diameter single pile test device comprises a combined type variable-diameter single pile test model, a storage cylinder and a centralizing frame. The stress and bearing capacity of the single pile structure can be improved, meanwhile, the effective utilization rate of the strength of a pile body material is increased, and when the combined reducing single pile sinks into soil, the sinking resistance can be reduced, and the combined reducing single pile can rapidly sink in place.
本发明提出一种组合式变径单桩与组合式变径单桩试验装置，其中组合式变径单桩包括：变径桩体、上部桩体和下部桩体，变径桩体为上宽下窄的锥筒结构，变径桩体的上螺纹口的外径大于变径桩体的下螺纹口的外径；变径桩体的上螺纹口与上部桩体之间螺纹连接；变径桩体的下螺纹口与下部桩体之间螺纹连接，下部桩体的外径小于上部桩体的外径。组合式变径单桩试验装置包括组合式变径单桩试验模型、储存筒和扶正架。本发明可提高单桩结构的应力和承载能力，同时提高桩体材料强度的有效利用率，而且将组合式变径单桩沉入土里时，可减小下沉的阻力，快速下沉到位。
