Foundation pile integrity detection method and device
The invention discloses a foundation pile integrity detection method and device. The method comprises the steps that a center temperature measuring optical cable is arranged in the vertical center of a reinforcement cage through a hollow pipe, a peripheral temperature measuring optical cable is evenly wound around the reinforcement cage, the reinforcement cage is hoisted into a pile hole, concrete is poured, the hollow pipe is pulled out, a light source is arranged and turned on, temperature values are measured through the temperature measuring optical cables during initial setting of the concrete, a controller records all the temperature values measured by the center temperature measuring optical cable to form a center temperature field and records all the temperature values measured by the peripheral temperature measuring optical cable to form a peripheral temperature field, the difference values between the temperature values of the center temperature field in a certain depth area and the temperature values of the peripheral temperature field in the depth area are calculated, and whether a large fluctuation range exists between the difference values or not is judged through comparison; and when the large fluctuation range exists between the difference values, that the integrity of a foundation pile has defects is judged. The foundation pile integrity detection method and device can detect the integrity of the foundation pile and have the beneficial effects that cost is low, construction is convenient, the foundation pile is not damaged, and detection is conducted under the low clearance condition.
本发明公开了一种基桩完整性检测方法及装置，该方法包括：将中心测温光缆通过空心管设置在钢筋笼的竖向中心，将外围测温光缆均匀缠绕在钢筋笼上，吊装钢筋笼到桩孔之内并浇筑混凝土，拔出空心管，设置并打开光源，在混凝土初凝时通过各自测温光缆测量温度值，通过控制器记录中心测温光缆测量的所有温度值形成中心温度场以及记录外围测温光缆测量的所有温度值形成外围温度场并计算某一深度区域的中心温度场的各温度值与该深度区域的外围温度场的各温度值之间的差值，比较差值之间是否存在较大波动范围；当存在时，判定基桩的完整性存在缺陷。本发明能够检测基桩的完整性，具有成本低、施工方便、对基桩无损伤以及在低净空条件下检测的优点。
