by From April 20 to 21, under the guidance of the Comprehensive Transportation Research Institute of the national development and Reform Commission, the overall expert group of the advanced rail transit key project of the 13th five year plan national key research and development plan, and CRRC Research Institute, Shanghai Metro maintenance and Guarantee Co., Ltd., the State Key Laboratory of rail transit control and safety and other units The rtforum smart rail transit conference and the second “2017 China rail transit operation and maintenance intelligent and Health Management Summit Forum” organized by RT rail transit magazine will be held in Shanghai.
Shanghai ouzhuo Industrial Development Co., Ltd.
(hereinafter referred to as “ouzhuo”) was invited to participate in the conference and forum activities, and brought the exhibits of composite reinforcement members + pre expansion chemical composite anchor bolts.
Shanghai ouzhuo industry is a large-scale comprehensive enterprise integrating scientific research and development, technical achievement transformation, design and construction, with a business scope throughout the country.
Together with Shanghai tieduan building materials Co., Ltd., we focus on the research and development of new composite materials.
We have a high-quality research and development team, and constantly innovate.
We have patented technology and advanced self-made technology in the field of subway tunnel bridge reinforcement products.
At present, we have passed the evaluation of authoritative institutions and contributed to the safety of subway tunnels.
The composite reinforced component has gathered five major innovations in technology, including high-strength mortar filler, special structural adhesive, high-strength carbon fiber, high-strength special steel and other materials.
It also has four self created advanced technologies, including early 3D measurement, numerical control compound finalizer, special high-pressure grouting machine and micro expansion rapid chemical anchor bolt.
As the expansion anchor bolt will expand during use, it may cause damage to the shield segment concrete.
The adhesive of the chemical anchor bolt needs 24 hours to solidify.
Therefore, the company has developed a micro expansion rapid chemical anchor bolt that can be quickly constructed.
It can be constructed immediately after planting, greatly improving the work efficiency and is suitable for the construction of the top surface and the wall.
Under the same strength, it has greater anchoring force than the single chemical anchor bolt or the expansion anchor bolt, and becomes a key part in the rapid reinforcement* Light weight for transportation * no need for electric welding and open fire operation * high strength, strong bearing capacity * convenient and fast construction * good anti-corrosion performance can minimize the impact on the clearance and operation time of the subway.
According to the monitoring data of Tongji University, the bearing capacity exceeds 63 tons, and the bearing capacity of the segment increases by 41%.
The cost is relatively low, the weight is light, the anti-corrosion performance is good, there is no need to dismantle the pipeline, and there is no need for large-scale equipment construction, The construction process is simple and efficient.
The subway tunnel reinforcement construction is a complex industry field.
It not only needs reliable technical and technological support, but also needs to complete the progress against time in the reinforcement operation.
Our products solve this technical difficulty.
Identify QR code focus on Shanghai Odyssey Odyssey and Shanghai tieduan will continue to innovate, and focus on the scientific research and development of new composite materials, centralized operation, and make contributions to the safety of urban rail transit construction.
Do you really only complain when friends and businessmen destroy cities and villages? The “rtforum smart rail transit conference” held in Shanghai from April 20 to 21 will focus on such topics as operation and maintenance intelligence and health management, rail transit communication system interconnection, intelligent and intelligent development, LTE comprehensive bearing and information security.
This activity was guided by the Comprehensive Transportation Research Institute of the national development and Reform Commission, the overall expert group of the key advanced rail transit projects of the 13th five year plan national key R & D plan, CRRC Research Institute and other units.
It was co organized by Shanghai Metro maintenance and Guarantee Co., Ltd., the State Key Laboratory of rail transit control and safety, the National Engineering Laboratory of high-speed train integration, and the Engineering Laboratory of the national rail transit engineering research center Undertaken by RT rail transit.
