In natural gas pipeline engineering construction process, digging holes, buried tube, welding is the most common and most major process, through the cycle repeated construction work, natural gas to get through the underground pipeline pecked cohesion to the destination. "Dig a pit for three days, buried pipeline 2 days, welding crossings 3 days, anticorrosive fill mouth 1 day, test 2 days, for a total of 11 days, a piece of duct can basic laid complete." Recently, the reporter to the datang town in the village of jiang "west-east gas second-line engineering zhuji section 93 pile homework site, zhuji LiuShengLi party branch secretary of eastern department introduced," engineering construction through cross, parallel homework, 11 days completed underground cloth tube than normal process, early two or three days."
At present, the second "west-east gas pipeline engineering 50.3 kilometers, already cloth pipe welding 48.1 kilometers, 85% of the completed project respectively, and 81% above the construction progress throughout the province 13 wear listed XianShiOu assignments section in third. LiuShengLi said, line construction in the contract period is three months ahead completed.
Very speed, from a very measures. "West-east gas second-line engineering value kilometers, zhuji section length since last May 10 construction, welding unit since from the original three increased to five, strengthened the pipe welding power. "Each tube long 800 meters, more than 70 HanKou ways, on an average day welding 10 crossing." LiuShengLi said, because it rained, located at the foot of the mountain 93 pile construction site road muddy, increased the difficulty in construction. "In order to not affect the natural environment along pipeline in the hillside topography, rock met, inconvenience blast way, instead of digging a ditch beaten broken stone law shock. Hit hammer HanKou rainy season, the canopy above can play with plain, and prevention and other assignments section, for instance in cross homework pile digging a ditch 93, welding, and pile. 94, no 95 pile is anticorrosive fill mouth. Because the resultant force arrangement process to ensure that rapidly advancing." project can
In the process, in order to try to not affect the villagers farming, the project also on-site learning how to control pipe of the excavation, threading operation after consideration of gap, leakage, etc.; For does not affect the villagers travel, such as when facing a hilly terrain need to dig a pit slope project department, cloth tube choice rushed digs a road at night before morning cloth pipe welding paved roads. Will
Zhuji city 670 thousand cubic meters for every demand for gas source, at present mainly from the natural gas compression station shangyu, through the tank trucks, sent to every 10 car capacity calculation of zhuji city, rijin in 4 million cubic meters of natural gas, can only basic guarantee residents about gas. Therefore, "west-east gas pipeline engineering is for second economic construction and security people living with" gas "important project, must take very move quickly and well propulsion.
"West-east gas pipeline engineering department second-line zhuji section, overcome period tension, the complex terrain, climate changeful disadvantage factors, such as many scientific arrangement assignment process, night and day, hardships, civilization, fighting the clock, drive plan, tapping a difficulty, in a relatively short duration realized the project schedule walk in the front rank for the whole project is progressing smoothly, laid a solid foundation.
