Introduction to Suzhou Metro Project
- Suzhou rail transit Group Co., Ltd., formerly known as Suzhou Rail Transit Co., Ltd. established in May2002, is a large state-owned enterprise directly under the city. The group completed the merger in 2013, forming a “five in one” pattern of rail transit planning, construction, operation, resource development and property management. At present, it has 7 departments, 7 branches (subsidiaries) and centers, and 5 foreign investment companies, with a total of more than 3000 employees.
- Suzhou rail transit closely follows the pace of Suzhou’s economic and social development, and timely starts the planning and construction of rail transit projects in accordance with the unified deployment of the municipal Party committee and the municipal government. In february2007, the first round of rail transit construction planning of our city was approved by the State Council. On april28,2012, after four years and four months of construction, rail transit line 1 was opened ahead of schedule, making Suzhou the first prefecture level city in China to build and operate rail transit. On december28,2013, rail transit line 2 was put into operation half a year ahead of the planned project preparation, and Suzhou rail transit officially entered the era of network operation.
- In january2012, the second round of construction planning was approved. In September of the same year, the extension line, line 4 and branch line of line 2 were started, and they are planned to be put into operation in 2016 and 2017 respectively. On december16,2014, the construction of rail transit line 3 was officially started. It is estimated that by 2020, the entire Suzhou rail transit line will present a network mode of “three vertical and four horizontal”.
Metallic expansion joint in Suzhou Metro Project
Metallic expansion joint is also known as, compensator, expansion joint and expansion joint. Compensators are divided into several types: corrugated compensator, sleeve compensator, rotary compensator, square compensator, etc. among them, corrugated compensator is more commonly used, mainly to ensure the safe operation of pipelines, and has the following functions:
- Compensate the axial, transverse and angular thermal deformation of the absorption pipeline.
- The expansion amount of corrugated expansion joint is used to facilitate the installation, sealing and disassembly of valves and pipelines.
- Absorb equipment vibration and reduce the impact of equipment vibration on the pipeline.
- Absorb the deformation of pipeline caused by earthquake and ground subsidence.
