The company issued shares to the controlling shareholders of Urban Construction Group, Guo Sheng Group and Shengtai Investment in a non-public manner, and purchased the core assets of engineering design and construction and infrastructure investment, as well as 36% equity and 65,438+00% equity (* * * including 65,438+00 equity) of infrastructure companies held by Guo Sheng Group and Shengtai Investment respectively.
Urban construction group promises not to undertake new contracting business except to complete the existing contract. In the future, all related businesses will be undertaken and carried out independently by listed companies, and related businesses will be developed through listed companies in the future. After the injection of assets, according to the profit forecast report, the basic earnings per share after the reorganization of the company will reach 0.77 yuan, and 20 12 will reach 0.83 yuan. 1973 company successfully developed a new technology of "vertical jacking method to build underwater intake and outlet" in the drainage tunnel construction of Jinshan Petrochemical Complex, which has been widely used in more than 30 underwater intake and outlet tunnels. This technical achievement won the second prize of 199 1 national scientific and technological progress.
1974, the drainage tunnel of Jinshan Petrochemical Complex was built by immersed tube method for the first time near Hangzhou Bay in China. 1980, the company undertook the capacity expansion test project of Shanghai subway 1 line, completed the shield tunneling of subway and the selection of tunnel lining structure, developed and applied the high-precision reinforced concrete segment technology, developed and applied the underground continuous wall construction technology and deep foundation pit support technology, which were widely used in Shanghai subway 1 line and Line 2 projects. In order to develop and apply soft soil tunnel construction technology, the company set up a test station when it was first built, and established a tunnel construction technology research institute at 1985.
From 1982 to 1988, the company undertook the north line project of Shanghai Yan 'an East Road Tunnel, and used the self-developed φ 1 1.3m grid hydraulic machinery to excavate the circular main hole, successfully crossing the shallow soil layer of Huangpu River and underground buildings on both sides. During the construction process, many new technologies, such as drilling and suction open caisson method and top-down construction method of underground continuous wall lining concrete, have been developed and applied. The project won the National Gold Award for Architectural Engineering and Luban Award, and its technical achievements won the second prize of the National Science and Technology Progress Award.
Since 1985, relying on the technical advantages of tunnel and underground engineering for more than 20 years, the company has actively expanded the field of civil engineering construction, from subway and river-crossing tunnel engineering to sewage drainage, power plant water intake and drainage tunnel, municipal pipeline engineering, foundation pit enclosure and foundation treatment engineering. Since 1990, the company has gradually entered the engineering fields such as roads, airports, expressways, elevated roads, overpasses, high-rise buildings, and electromechanical equipment installation. The company's construction field is gradually expanding, the construction output value is increasing year by year, and the profits of enterprises are constantly improving. The company has been rated as the national advanced construction enterprise, the national best construction enterprise and the top 100 construction enterprises in China for many times. 1993, the company was restructured into Shanghai Tunnel Engineering Co., Ltd. and listed on the Shanghai Stock Exchange on June 28th, becoming the first listed company of China construction enterprises.
The company attaches great importance to corporate management and capital management. The company has established and improved road and bridge companies, foundation grouting companies, shield companies, trench wall companies, structure companies, equipment companies, concrete mixing stations and concrete component companies. The company also focuses on the transformation of machinery factory and building waterproof material factory. This machinery factory has become a professional manufacturer of shield tunneling machines in China, and has manufactured more than 50 shields with diameters of1.5m ~ 7.65m. The manufacturing technology of shield is at the leading level in China.
From 65438 to 0998, the company acquired and controlled Shanghai No.1 Municipal Engineering Co., Ltd., Shanghai No.2 Municipal Engineering Co., Ltd. and Shanghai Highway and Bridge Engineering Co., Ltd., and acquired Shanghai Tunnel Engineering Rail Transit Design Institute and Shanghai Urban Construction Design and Research Institute. The company's total share capital reached 376 million yuan.
199, the company invested 396 million yuan to participate in the operation right of Hu Jia Expressway owned by Shanghai Highway Construction Corporation in 17, which took a big step in capital operation. In the same year, the company invested 400 million yuan to invest in Ningbo Changhong Tunnel, and invested in major projects in the form of BOT for the first time.
During the period of 1999, the company built the Shanghai Outer Ring Tunnel, the largest immersed tunnel in China, and successively completed the large-scale dry dock project and the pouring construction of 8-lane large-scale immersed concrete joints.
In 2000, other projects were carried out, such as Ningbo Changhong Tunnel, Guangzhou Metro Line 2 Tunnel, Shanghai Metro Pearl Line Phase II, Suzhou River Regulation Project, Outer Ring Road and Interchange Project, Waigaoqiao Power Plant water intake and drainage tunnel, Zhangzhao Expressway and so on. The company also actively explored the overseas civil engineering market, completed the tunnel project of the northeast line of Singapore Metro 10 km, and won the bid for the construction of sewage discharge tunnel project.
After 2000, on the one hand, the company continued to increase the undertaking capacity of engineering construction, and at the same time began to adopt a multi-directional development trend. A large number of underground engineering projects in China have expanded the company's scale day by day, and its technical advantages in the construction field have become increasingly obvious. World-class projects such as "Repair of Line 4" and "Yangtze River Tunnel" have been completed. At the same time, the investment scale has been gradually expanded, and a series of projects have been invested in Dalian Road Tunnel, A30 Suburb Ring Road, Qiantang River Tunnel and Changzhou Urban Expressway.
In 2005, the 6.34m EPB shield machine "Pioneer" with completely independent intellectual property rights was successfully developed in the National 863 Plan, and in 2007, the 1 1.22m slurry balance shield machine "Yuejie" was developed. Shield machine has not only achieved excellent sales performance in China, but also successfully entered the international market. The "preemptive strike" consciousness of the tunnel company determines that the tunnel company will become a large-scale compound group company and a technology advantage integration company at the beginning of the 2/kloc-0 century. "Winning by technology" is not just a slogan, but an action.
