Monitoring method for leakage of underground space waterproof curtain
The invention discloses a monitoring method for leakage of an underground space waterproof curtain. The monitoring method comprises the following steps that: step 1, a monitoring area is established on the outer side of the underground space waterproof curtain; step 2, when the waterproof curtain leaks, an expansion object naturally expands after meeting water, so that a cantilever beam is bent upwards, and the capacitance value of an upper polar plate and the capacitance value of a lower polar plate are changed; and water on the outer side of the waterproof curtain flows to a leakage point, so that micro pressure is applied to an optical fiber, and the conduction characteristic of light in the optical fiber is changed; step 3, the capacitance value and the strain value collected by a single-chip microcomputer are sent to a data terminal through a wireless communication module; and a micro-motion pressure field signal is detected by a micro-motion sensing optical fiber; and step 4, theacquired signal is comprehensively analyzed to locate the position of a leakage point and evaluate the leakage intensity. According to the method, tiny leakage points of the waterproof curtain can beeffectively and accurately monitored, the leakage degree can be effectively and accurately evaluated, and dangerous events are avoided.
本发明公开了一种用于地下空间止水帷幕渗漏的监测方法，其包括以下步骤：步骤一、在地下空间止水帷幕外侧建立监测区域；步骤二、在止水帷幕发生渗漏时，膨胀物遇水后发生自然膨胀使悬臂梁向上弯曲，使得上极板和下极板的电容值发生了变化；止水帷幕外侧的水将向渗漏点流动，从而对光纤有微压力，导致光在光纤中的传导特性发生了改变；步骤三：单片机采集到的电容值和应变值通过无线通信模块发送给数据终端；微动传感光纤检测到的微动压力场信号；步骤四：将获取的信号综合分析以定位渗漏点位置以及评估渗漏强度。该发明能有效而精确地监测止水帷幕细微的渗漏点及评估渗漏程度，避免危险事件的发生。
