1、寒区在用预应力连续梁、连续刚构桥箱梁开裂成因及加固技术研究,黑龙江省城乡建设科技进步三等奖,第一完成人
I ever have been responsible for more than 50 technical service items, such as: Limin Bridge of Hengdaohe; Harbin unsafe bridge reconstruction projects in 2014; Harbin city bridge reconstruction projects in 2014; highway management maintenance bridges engineering design projects of Shangzhi, Wuchang, Yichun in Heilongjiang Province; many bridges monitoring projects such as Jinzhou Bridge, Wolong river Bridge, Xiangfeng river Bridge in Dalian and Hunchun cable-stayed bridge; Qingmei Bridge in Mudanjiang and lots of bridges detecting projects such as Zhengyi Road viaduct, Yimiaopu viaduct, Hongqi Street viaduct and so on in Harbin. Now it has been combined closely with the scientific research and technical services, also that has good social reputation.
I obtained 25 university-enterprise cooperation r&d projects, received funding more than 20 million Yuan, and a number of projects had been taken in engineering practice, and achieved remarkable economic and social benefit.
“Optimal Design and Construction Technology of The Simple Support and Continuous Beam” obtained the third prize of Heilongjiang province Science & Technology Development. Research achievement optimal section and reduce negative bending design,reduce hoisting construction, improve the construction speed. It will provide technical support of bridge construction, design, maintenance and management for Heilongjiang province and even the whole country. Research achievement come up to internal advanced level. Research results has savd direct cost 1.30675 million yuan , and will save indirect cost 4.876 million yuan a year.
“The Research of The Compound Mortar and Prestressed Strand Strengthening” obtained the second prize of Heilongjiang province Science & Technology Development of city and countryside construction in 2014, and this technology has obvious advantages compared with other strengthening methods, construction is convenient, cost is low, it has the remarkable social and economic benefits. This scientific research was applied to Hongdianzi Bridge and No.2 highway-railway interchange and many other bridges in maintenance engineering, also totally save project cost about 68.7 million Yuan.
“Reseach on Cracking Reason and Reinforcement Technique about Pprestress-Ccontinous Beam and Box Girder of Rigid Frame Bridge in Cold Region”obtained the third prize of Heilongjiang province Science & Technology Development of city and countryside construction in 2015. It proposed a new bridge reinforcement technology ,which integrated approach combining three types of bridge reinforcement including external prestressing, pasting steel plate and closed fracture methods,and developed a new type of reinforcement anchorage and tensioning device, and it proposed a detection technology of prestressed continuous girder Bridges and continuous rigid-frame box girder in cold region.It saved a lot of manpower , material resources and financial resources in the process of the design and construction and reinforcement of bridge,amounted to 92.7818 million Yuan.
