1. Introduction to Oyun Tolgoi Copper-Gold Mine Project:
1. China Nonferrous Mining Construction Group Corporation, China Nonferrous Engineering Design and Research Institute and Ivanhoe Mining Co., Ltd. successfully signed the Oyun Tolgoi copper-gold project cooperation framework agreement this time, which will effectively promote the development and development of the project. .Implementation of global resource development strategy. Ivanhoe Mines Canada Ltd. is the first company listed on the Toronto Stock Exchange of Canada and the Australian Stock Exchange. They are the first successful company in global mining exploration and development, project expansion and resource investment. As China’s leading enterprise in the field of international non-ferrous metal mining development, China Nonferrous Mining Construction Group Co., Ltd. has strong project development, construction, production and contract management capabilities, and has rich experience in international project development and investment construction. China Nonferrous Engineering Design and Research Institute is a large-scale comprehensive scientific and technological entity with high international reputation that integrates engineering design, scientific research, and technical consulting. Its expertise is especially embodied in the design of non-ferrous metal mining. The three parties have a good reputation and advantages in international mining development, making the construction of the Oyuntolgoi copper-gold mine in Mongolia present an attractive prospect.
2. China-Canada tripartite cooperation in Mongolia’s Oyun Tolgoi copper-gold mine project signed a framework agreement. In order to implement the global resource development strategy and implement the development policy of establishing a non-ferrous metal raw material base in China, Canada Ivanhoe Mines Co., Ltd. The company, China Nonferrous Metals Mining Construction Group Co., Ltd., and China Nonferrous Engineering Design and Research Institute of the three-party cooperation development and construction of Mongolia * Oyun Tolgoi copper-gold project framework agreement was formally signed in Beijing on July 31. Zou Qiao, Secretary of the Party Committee and Executive Deputy General Manager of China Nonferrous Mining Construction Group Co., Ltd. presided over the signing ceremony. Zhang Xiuli, Deputy General Manager of China Nonferrous Mining Construction Group, Kang Nanjing, Dean of Nonferrous Engineering Design and Research Institute, and Ivanhoe Mining Co., Ltd. The vice chairman of the company, Mr. Gordon Toll, signed the agreement on behalf of the three parties. The Oyun Tolgoi Copper-Gold Mine is located in the southern Gobi Province of Mongolia. It is a 4.5-kilometer mineralized zone, only 80 kilometers from the northern border of China. Exploration shows that the total ore resources of the mine are 1.6 billion tons, containing 580 tons of gold and 12 million tons of copper. During his visit to Mongolia in June this year, President Hu Jintao said, “China will encourage strong Chinese enterprises to invest in Mongolia, and we are willing to take the development of mineral resources and infrastructure construction as the key areas of cooperation between the two countries in the future.” Hu The chairman’s speech and my *about the US$300 million “international cooperation preferential loan” to Mongolia* immediately aroused strong responses from Mongolia* and related parties.
3. The mining industry is the economic pillar of Mongolia*. In recent years, Mongolia* has stepped up its efforts to attract investment and cooperate in the development of minerals. The Oyu Tolgoi copper-gold mine is a large project of Mongolia* investment cooperation. The mine is jointly held by Canada’s Quayshill Resources Company and Mongolia*. They hold 66% and 34% of the mine’s shares, respectively. The global mining giant Rio Tinto, as the controlling shareholder of Quayshill Resources, is responsible for the operation and management of the mine. It is understood that the Oyu Tolgoi copper-gold mine has the largest copper reserves in the world, and it is also the largest mining development project in Mongolia so far. The picture shows the production workshop of Oyu Tolgoi Copper-Gold Mine.
2. Introduction of Songjiang flexible waterproof casing used in Oyun Taolgai copper-gold mine project:
1. Classification of flexible waterproof casing: According to the standard atlas, it can be divided into: *standard and non-standard. *Standard type waterproof casing refers to the selection and production of materials in accordance with the 02S404 or 02S312 standard atlas related to the Ministry of Construction. There are strict requirements on flange thickness, wing ring thickness, pipe diameter and thickness. Non-standard means that when the shape and general structure meet the standard atlas, the flange thickness, wing ring thickness, pipe diameter and thickness are considered to be relaxed when selecting materials. Strictly speaking, these are unqualified products. Of course, * The relaxation of the standard within a certain degree does not * affect the use, but the excessive relaxation of the standard will affect the use performance.
2. According to the atlas, it can be divided into: S312 flexible waterproof casing and 02S404 flexible waterproof casing. Both have different dimensions and structure.
3. Specification of flexible waterproof casing: DN50mm—DN3200mm
4. The difference between rigid waterproof casing and flexible waterproof casing: rigid waterproof casing is a steel pipe with a wing ring (a ring made of steel plate is sleeved on the steel pipe), installed in the wall (mostly concrete wall), and used for general pipes Through the wall, it is conducive to the waterproofing of the wall; in addition to the outer wing ring, the flexible waterproof casing also has a retaining ring inside. The flange inner wire is sold in a complete set or can be processed by yourself for pipes that require shock absorption. Road, such as when the pipe connected to the water pump penetrates the wall.
5. It is mainly used in different places. Flexible waterproof casings are mainly used in high-demand places such as air defense walls and pools. Rigid waterproof casings are generally used in basements and other places where pipes need to pass through. *Generally, a casing pipe is used when making a pool. It is a channel from the pipe to the pool. However, ordinary casing is difficult to seal, so there will be water leakage between the casing and the pipe, and between the casing and the wall is also easy to leak. Using only the waterproof casing can solve the water leakage between the casing and the wall, but cannot solve the sealing between the casing and the pipe. The flexible waterproof casing can solve two problems.
6. The casing can be divided into: ordinary casing-2-4 cm thicker than the pipe to be used, fixed in the wall or board, and the pipe passes through it. Flexible casing-is to seal between the casing and the pipe with a flexible material to achieve a sealing effect. Rigid casing-is the sealing effect between the casing and the pipeline with a rigid material. Waterproof casing-the environment where the casing is used is to prevent liquid from leaking or leaking (such as pools, septic tanks, basements, etc.). It is to add no less than 1 circle of waterproof wings on the outer wall of the casing. When the pipe is poured into the wall, it becomes a whole, and will not leak due to cracks due to expansion and contraction factors.
7. Pipes that enter the home from underground. Rigid waterproof casing should be installed when passing through the outer wall of the building: casing that penetrates the wall (pool, board, etc.). Divided into two kinds of rigidity and flexibility. After the installation is completed, deformation is allowed—flexibility; deformation is not allowed—rigidity. The main products are: steel waterproof casing, GT-type steel waterproof casing, rigid waterproof wing ring, stainless steel waterproof casing, S312 flexible stainless steel waterproof casing, rigid waterproof casing, airtight casing, resistance casing, and piercing Processing of hollow wall embedded casing, floor square casing, roof inclined casing, round duct, PVC waterproof embedded casing and various embedded iron parts.
