Following the completion of the first section of Thailand's natural gas pipeline laying project on February 7,,On March 28, good news came again from the project.。The smallest diameter made in China by China Railway Construction Heavy Industry(φ0.914 meters)The rapid roof-laying machine completed 840 meters of tunneling construction in 15 days.,After passing through several wire tower piles, it successfully helped the tunnel of the second section to run through accurately.,It has refreshed the world record of the same level of pipe diameter pipeline excavation construction.,It marks that the domestic rapid roofing technology has reached the world's leading level.。
Precise penetration of equipment through electric tower pile foundation
It is reported that,Thailand Natural Gas Pipeline Phase I Project is located in the south of Bangkok.,Pipe diameter 0.914 meters。The length of this construction section is 840 meters.,Divided into 11 pipe sections,Each section is about 78 meters.,The whole line must pass through the middle of the pile foundation of the high-voltage power line tower.,It is required to cross 5 electric towers in total.,The distance between the pile foundations of the electric wire tower is only 3 meters.,The construction is extremely difficult.。
Device origination
The rapid topping machine of China Railway Construction Heavy Industry Co., Ltd. started on March 13.,The driving speed is steady and continuous at 0..6 meters,This means that a single pipe can be completed in less than 3 hours.(78 meters)Construction,The rest of the time is used for pipe connection work.,It took only 15 days to complete the roofing work of 840 meters of pipeline.。
For items with extra small diameter、Very long distance、Curve tunneling and other extreme working conditions,New Guidance System Developed by China Railway Construction Heavy Industry,Comparable to an underground project“The eye of wisdom”,Make the equipment successfully cross between five electric tower pile foundations along the way.,The horizontal construction accuracy is generally controlled within 10 cm.,Precision control has reached the world's leading level.。The stability of the equipment is fully verified.、High efficiency and advancement,It further consolidates the authority of Railway Construction Heavy Industry in the field of international tunnel equipment.,It provides strong support for pipeline construction under extremely complex conditions and intelligent technology of global equipment.。
