近些年来,随着我国国防及国民经济建设的蓬勃发展,我国的海底电缆建设也出现了高潮。人们在实践中提高了海缆敷设水平,也对海缆敷设提出了更高的技术要求。如何才能按照调查已确定的最佳路由进行海缆敷设,便成了海缆敷设工程中的关键。本文介绍的540型数字式测距装置是一种成功地应用于浅海海缆敷设的定位仪器。该仪器具有连续定位、精确度高、便于掌握,易于使用等优点。该装置在我国近海海缆敷设中的广泛应用,无疑将促进我国敷设技术水平的提高,促进我国海缆事业的发展。
In recent years, with the vigorous development of our national defense and national economic construction, the construction of our submarine cable has also reached a climax. People in practice increased the level of submarine cable laying, laying a higher technical requirements for submarine cable. How to conduct submarine cable laying according to the best route that has been determined by the survey has become the key issue in the submarine cable laying project. This article describes the 540 digital ranging device is a successful application of shallow sea submarine cable positioning instruments. The instrument has continuous positioning, high accuracy, easy to grasp, easy to use and so on. The extensive application of the device in the laying of offshore submarine cables in China undoubtedly will promote the improvement of the laying technology in our country and promote the development of the submarine cable business in our country.
