First use of Ovim sensor technology in good performance in China (Chart)

The railway traffic network has been extended all over the country, and foreign equipment has been introduced. Shijiazhuang Jinan passenger line is too (the original) green (Island) passenger Middle East Jinan passenger line, west of Shijiazhuang Taiyuan Passenger Dedicated Line, is the national express railway network planning "vertical and horizontal" four "horizontal". Shi Ji Tiexi Shijiazhuang middle high, mainly through Hengshui north station, Dezhou station two station, East Ji'nan station. After the completion of the Shiji passenger dedicated line, the Tai Qing passenger dedicated line will connect the whole line to communicate in Shanxi, Hebei and Shandong provinces.

Recently, Liuzhou OVM machinery Limited by Share Ltd (hereinafter referred to as "OVM prestressed") subsidiary - ouweimu testing company Railway precast box girder tensile stress strain monitoring test of Jinan passenger line project on the stone of success, this is the first use of ouweimu sensor technology in railway precast box beam in the.

2015, to promote the scientific research strength, strengthen the use of prestressed technology in actual project, ouweimu testing company and the Third Railway Survey and Design Institute Group Co. Ltd. (hereinafter referred to as railway hospitals to achieve cooperation, to Shi Ji) eighteen Bureau of China Railway Passenger Dedicated Line beam field as the background of engineering, prestressed railway precast box girder tensile stress strain monitoring test. Ouweimu testing company at the end of July 2015, admission to install the sensor system, start test.

In this experiment, 4 prefabricated box beams were selected as the research object, and the product quality, tension control precision, reliability and work efficiency of the intelligent tensile equipment were studied. During the tensioning test, the prestressed cable force monitoring sensor and concrete strain sensor are embedded in the precast beam body to monitor the stress state of prestressed reinforcement and concrete during the tension process.

Three main technical points are: the test of prestressed reinforcement channel in each piece of precast beam Liang Duan and cross location, select 18 point mounted magnetic flux sensor, for monitoring the prestressing stress; selected 24 key points for installation of vibrating wire strain gauge, the precast concrete strain monitoring in the installation of precast beam; acquisition system, all the sensors in the system of integrated wiring.

The whole experiment was divided into pre tension, initial tension and final tension, the static load of four links, each link in the experiment, the sensor ouweimu testing company flux monitoring system are fully reflected in the technical advantages of prestressed monitoring. After half a year of hard work, in January 2016 the successful completion of the test, the data and the expected design fully consistent with the test results, has been highly recognized by the railway hospitals.

Ouweimu years shoulder to enhance the level of prestressed technology and application as its mission, is committed to providing customers, shareholders, employees, society to create high quality value "of the enterprise mission, adhere to Scientific Outlook on Development, encourage technological innovation, new technology emerge in an endless stream of patent. The test is completed, it is a great step OVM prestressed technology, at the same time ouweimu magnetic flux sensor technology will be extended to the railway beam which is a new field in advance.
