2013年1月30日,国家知识产权局下发了“一种高精度智能双核井深测量装置”的专利证书,标志着水利部长江勘测技术研究所又一成果获国家实用新型专利。在水利水电、桥梁隧道、市政工程等工程勘察中,为了获取地下岩土体的声波速度、电阻率、岩石产状等原位物理参数而进行工程测井的过程中,一般采用测绳、皮尺等测量工具或者在电缆上做深度标记进行深度计数。这些方法均为静态方式,
On January 30, 2013, the State Intellectual Property Office issued the patent certificate of “a high-precision intelligent dual-core well depth measuring device”, marking another achievement of the State utility model patent by the Yangtze River Survey Technology Research Institute of the Ministry of Water Resources. In water conservancy and hydropower, bridge tunnels, municipal engineering and other engineering investigations, in order to obtain underground rock and soil acoustic velocity, resistivity, rock production and other physical parameters in situ engineering logging process, the general use of rope, tape measure Depth gauging such as measuring instruments or deep marks on the cable. These methods are static way,
