Embodiment Construction

[0038] It is used for the parallel electrical method directional detection method and device for the hidden danger body in the hardened dam. This invention aims at the current problem that the direct current method is difficult to install the electrode after the hardened dam is hardened. A new device and detection method is proposed to achieve the hidden danger of the dam The purpose of effective identification. The specific working methods are divided into the following aspects:

[0039] 1. Invented the skeleton structure of the electrode device: such as figure 1 As shown, the internal structure of the electrode device includes a cylindrical copper rod 1 with a length of 400 mm, a cylindrical copper rod 1 with a conical tip 2 with a length of 10 mm at the bottom end, and the conical tip 2 facilitates the insertion of underground media; the cylindrical copper rod 1 The two sides of the other end are polished into a groove 3 with a length of 100mm. The groove 3 is used to facilita...

Abstract

The invention relates to the field of potential dame risk detection, and particularly relates to a hardened dam potential risk detection method and device applying the parallel electrical survey. The device comprises an electrode for an electrical prospecting apparatus, wherein the frame inside the electrode comprises a copper bar and a transfusion duct; conductive sponge and conductive lint sequentially coat the outer part of the middle part of the electrode. The method and the device have the advantages of convenience in field operation, flexibility in operation, low labor intensity and wide application environment since a charging mode electric hammer is adopted to drill the surface of hardened dam; the drilling hole has a small diameter, so that the work for repairing the hardened surface layer of the dam in later phase can be facilitated.

Description

Technical field [0001] The invention relates to the field of detection of hidden dangers in dams, in particular to a method and device for detecting hidden dangers in hardened dams using a parallel electrical method. The invention improves the working method of detecting hidden dangers in dams and the contact coupling method between electrodes and hardened surface, and is mainly applied to dams. , Mountain ponds, highways, runways, building grounds and other surface hardening facilities, as well as natural or artificial geological bodies such as exposed mountains, roadways, and foundation pits. Background technique [0002] The dyke is an important part of the flood control engineering system and the last barrier against floods. With the increase of its operating life, the leakage problem of dams becomes more and more prominent. In order to effectively carry out the work of eliminating dangers and strengthening, it is necessary to accurately calibrate the location, scope and con...
