Building foundation pile lossless detection method
The invention discloses a building foundation pile lossless detection method. The foundation pile length is determined according to the thermophysical property, different from pile surrounding soil, of a pile body material. The building foundation pile lossless detection method comprises the steps that drilling is conducted nearby a foundation pile, and a heat transfer pipe is arranged; setting ofa measuring hole is determined according to the foundation pile diameter; heating liquid is led into the heat transfer pipe, and data of a temperature sensor in the measuring hole are obtained; and the foundation pile length is determined according to the data of the temperature sensor. Through the building foundation pile lossless detection method, the problems that the traditional field excavation engineering amount is large, a pile body structure is damaged due to drilling and coring, and low-strain detection precision is low are solved; and accordingly, low-manufacturing-cost foundation pile lossless detection is achieved.
一种建筑基桩无损检测方法，利用桩身材料与桩周土不同的热物性确定基桩桩长，包括：在基桩附近钻孔设置传热管；根据基桩桩径确定测量孔的设置；传热管中通入加热液体，获取测量孔中的温度传感器的数据；根据温度传感器的数据，确定基桩桩长。通过本发明的建筑基桩无损检测方法，克服了传统现场开挖工程量大，钻孔取芯破坏桩体结构，低应变检测精度低等问题；从而实现低造价的基桩无损检测。
