XIANG LIMING / LI SIHAO / WANG HONGSHENG / GUO YANHUA

The invention relates to an elevation detection alarm device and method for concrete pile foundation pouring, and belongs to the technical field of pile foundation pouring. Mainly aiming at the problem that the existing detection device used for pouring the concrete pile foundation is directly connected with a steel cage in the pile foundation, so that the detection device is inconvenient to disassemble, the following technical scheme is provided: the detection device comprises the pile foundation and the steel cage mounted in the pile foundation, and further comprises a detection sensor, the top end of a single steel bar of the steel cage is fixedly connected with an auxiliary rod, and one side of the detection sensor is fixedly connected with a fixing clamp capable of clamping the auxiliary rod. Before the liquid level of concrete reaches the detection sensor, when the liquid level of the concrete rises to submerge the floater gradually, and when the floater is completely submerged by the concrete, three different electric signals can be generated. The detection sensor is connected with the auxiliary rod, then the auxiliary rod is connected with the steel cage, and the purpose of conveniently taking out the detection sensor outside the pile foundation through the auxiliary rod can be achieved.

本发明涉及用于混凝土桩基灌注的标高检测报警装置和方法，属于桩基灌注技术领域。其主要针对现有的混凝土桩基灌注所用到的检测装置直接与桩基内的钢笼连接，会给检测装置的拆卸带来不便的问题，提出如下技术方案：包括桩基以及安装在桩基内的钢笼，所述还包括检测传感器，所述钢笼的单根钢条顶端固定连接有辅助杆，所述检测传感器的一侧固定连接有能夹住辅助杆的固定夹，包括以下步骤：灌注混凝土，在混凝土液面到达检测传感器前、当混凝土液面上升逐步淹没浮子时、当混凝土完全淹没浮子时会产生三种不同的电信号。本申请通过将检测传感器与辅助杆连接，随后将辅助杆与钢笼连接，可以在桩基外部通过辅助杆达到便捷取出检测传感器的目的。
