DLFS Anchorage System Technology Corporation is the world leader in the field of anchoring connection," and it is also a national invisible champion enterprise in China.
Anchor connection is a very subdivided field, but in railways, bridges, municipalities, construction, wind power, nuclear power and other fields within sight, anchors are almost everywhere-the supporting members are securely fixed to concrete through anchors In addition, it can effectively withstand various wind loads, snow loads, and vibration loads. At the same time, accidental factors such as fires and earthquakes must be considered.
In the past, the technology of anchoring connection products was in a leading position in Europe. Europeans have used nearly 100 years to gradually improve the performance of the anchors, and many family businesses have been formed in this field that have lasted for nearly a hundred years.
Different from the original anchoring technology, the in-situ replacement anchoring technology does not require re-drilling, and the load-bearing is installed quickly, which greatly shortens the maintenance time and reduces the maintenance cost.
DLFS is promoting the intelligentization of anchoring technology, that is, adding intelligent electronic components to the anchors, so that the anchoring force can be monitored in real time, so as to achieve more accurate risk prediction and timely maintenance. Intelligent anchoring technology has the potential to enter the global market.
From 2008 to 2010, China's high-speed rail construction was rapidly rolled out. DLFS has successively won bids for various high-speed rail anchoring projects.
Anchors are used in the tunnels and bridges of high-speed railways. They are closely related to the safe operation of high-speed railways and are key components for strict control. The service life of hot-dip galvanized anchor bolts is about 20 years, and it is necessary to reposition and drill holes when replacing the anchor bolts. The railway has a strict operation management process. The time left for the replacement of anchors for each line maintenance is very short, only 4-5 hours between 12 o'clock in the evening and 5 o'clock in the morning. The construction time is extremely short, and a large amount of mobilization is required to complete the replacement. The maintenance and replacement cost of personnel and vehicle equipment is extremely high in the future.

The application of anchors is not only on railways, but also roads and bridges, commercial buildings, municipal pipe corridors, wind power, nuclear power, etc. There are a large number of applications for anchors. In these areas, China has just experienced or is experiencing rapid progress. Construction.
In 2015, after the application of in-situ anchoring technology, DLFS began to invest in research and development in intelligence, implanting chips and sensors into the anchoring structure, monitoring the force of the anchoring in real time, and judging the status of the anchor based on the collected data . "This kind of intelligent anchoring system solution is not available in developed countries in the world. 5G communication technology can solve the problem of signal transmission speed. Once applied on the railway, the intelligent sensing and predictive technology of railway ancillary facilities can truly realize the Internet of Things.
At the beginning of 2020, DLFS CTO Dr. Liu went to the University of Stuttgart, Germany for technical exchanges, which is quite famous in the field of anchoring technology. There, he met a professor in the field of anchoring. After the professor understood the concept of intelligence, he lamented that the application research of Chinese companies in the field of anchoring has come to the fore. “Europe’s population is seriously aging. The anchors of the infrastructure have been used for many years and are facing a large number of replacements. If the traditional methods are used to solve the maintenance of the anchors, it will be time-consuming, laborious and costly. If the intelligent sensing anchoring technology is added, It will save a lot of financial and material resources.
