Telescopic steel pipe spiral pile foundation for active cooling in frozen soil area and method
The invention discloses a telescopic steel pipe spiral pile foundation for active cooling in a frozen soil area. The telescopic steel pipe spiral pile foundation comprises a supporting spiral pile, anair supply system used for providing cooling air for the supporting spiral pile, an adjustable supporting mechanism arranged at the upper end part of the supporting spiral pile and used for bufferingthe position change of a tower foundation due to seasonal thaw sinking or freezing pulling, a hydraulic adjusting system used for providing power for the adjustable mechanism, and a fixing system arranged at the upper part of the supporting spiral pile and used for limiting the adjustable supporting mechanism. According to the telescopic steel pipe spiral pile foundation, the length of the spiralpile can be adjusted according to the change condition of a frozen soil layer, an active cooling device can be adjusted to reduce the temperature of frozen soil according to the change condition of the frozen soil layer, the influence of freezing pulling or sedimentation of the spiral pile foundation on an upper-layer building is reduced, and the stability of the overall structure is guaranteed through automatic fastening of an intelligent fastening system; and according to the telescopic steel pipe spiral pile foundation, when the pile top construction elevation has errors, the telescopic steel pipe spiral pile foundation can be adjusted through the hydraulic system to be suitable for being applied to areas where the pile top elevation is difficult to control due to topography fluctuation, and the application range of the telescopic steel pipe spiral pile foundation is further enlarged.
本发明公开了一种用于冻土区主动冷却的可伸缩钢管螺旋桩基础，其包括支撑螺旋桩、用于为支撑螺旋桩提供冷却风的送风系统、设置在支撑螺旋桩的上端部并用于缓冲塔基础因发生季节性融沉或冻拔而位置变化的可调节支撑机构、为可调节机构提供动力的液压调节系统、以及设置在支撑螺旋桩的上部用于对可调节支撑机构进行限位的固定系统。本申请中可以根据冻土层的变化情况调节螺旋桩长度和主动冷却装置降低冻土温度，减小螺旋桩基础冻拔或沉降对上层建筑物的影响，且利用智能紧固系统自主紧固，保障整体结构的稳定性；本申请中在桩顶施工标高有误差时可以通过液压系统调节，适合应用在地形有起伏难控制桩顶标高的地区，进而增大钢管螺旋桩基础适用范围。
