Deep foundation pit waterproof curtain leak detection method
The invention provides a deep foundation pit waterproof curtain leak detection method which comprises the following steps in specific: S1, dividing the detecting working area of a foundation pit waterproof curtain structure; S2, arranging basic equipment, and mounting in-well observation electrodes and out-well observation electrodes; and S3, carrying out detection, before and after rainfall, detecting and recording electrical resistivity between two adjacent in-well observation electrodes and between the in-well observation electrode and a corresponding out-well observation electrode, and comparing change of the electrical resistivity before and after rainfall. With adoption of the deep foundation pit waterproof curtain leak detection method, the leak point position of the waterproof curtain can be judged, so that the waterproof curtain is not damaged, and the engineering quality is improved; a measuring component does not need to be buried in advance, and detecting equipment can be repeatedly used to lower the construction cost; and the electrical resistivity of the waterproof curtain and soil are considered comprehensively to improve the detecting precision.
本发明提供一种深基坑隔水帷幕渗漏检测方法，具体步骤如下：步骤一，工作区划分，对基坑隔水帷幕结构进行的检测工作区的划分；步骤二，基础设备布置，进行井内观测电极和井外观测电极的安装；步骤三，检测工作，降水前、后分别对相邻的两个井内观测电极之间以及对应的井内观测电机和井外观测电极之间进行电阻率进行检测并记录，对比降水前后电阻率的变化。本发明方法能够对隔水帷幕的渗漏点位置进行判断，这种方式不会对隔水帷幕产生破坏，提高了工程质量；无需预埋测量部件，检测设备可重复使用，降低了施工成本；综合考虑隔水帷幕和土壤的电阻率，提高了检测精度。
