Ten construction company built in Huizhou CNOOC Huizhou Refining and Chemical Ike Si large equipment hoisting operations, from May 1, 2017 onwards, to end on November 5, 2017, which lasted 189 days, lifting a total of 35 large towers, hoisting total Heavy 2700 tons, large hoisting safety, high quality, completed on schedule.
Large-scale hoisting environment is harsh. Project near the southern coast of Guangzhou, hoisting encountered a number of strong typhoons affect the scene, direct stoppage. Ten construction projects to take effective measures to prevent typhoons, rainy season, including large cranes Climbing poles, reinforcement equipment placed on the support, digging ditch drainage, the face of volatile and extremely hot weather, take the erection of rain, Sun shelter, summer 'cool' and other measures to prevent summer heat shelter, Site workers safe and smooth operation.
Installation and lifting tension and orderly From May 1 to 31, with 270 tons of crawler cranes to complete the first batch of large equipment to the scene; Since then, ten built project department in accordance with the project plan, beginning on June 1, 750 tons Level cranes entered the group car, setting off a wave of large-scale equipment installation climax, and on August 7 to complete large-tonnage hoisting equipment, 750-ton crane withdrew; then use 270 tons of crawler cranes hoisting a third batch of equipment, Hoisting to be completed on November 5, the entire hoisted organization in an orderly manner.
Overcome the technical difficulties of hoisting.First of all, most of the equipment is plate lugs, ten built scaffolding in advance set up a good scaffolding, in order to lifting personnel in place after picking the hook to the top of the tower to reduce the safety risk; second part of the lug design is not reasonable , Hoisting ring can not be inserted into lugs, the project department to design and manufacture lugs, the scene welding and inspection, to ensure the smooth lifting, thus ensuring the construction period.
Implementation of modular increase efficiency.Each tower arrived at the scene, ten built in accordance with the modular construction planning, organization shelter, tube workers, riveting, welding, electrical, corrosion, insulation and other power assault construction, such as the presence of the section Tower equipment in the field of welding on the site into one, and then the pressure test tower equipment; Another example is the attached tower structure, piping, electrical lighting, corrosion, insulation and other construction, all in the tower body flat state installation is completed, the pipeline pressure Complete, and then the implementation of a large tower modular lifting installation, so that the tower lights, quality and quantity of security, saving time and effort reduce costs, efficient completion of large equipment hoisting in accordance with the schedule, to the owners to submit a satisfactory answer sheet.
During the whole period of hoisting, there was also heavy sweat in the rain. There were also remarkable achievements in the scorching sun. Ten built a consistent and responsible attitude and credibility, and solved the problems for the owners, and sincerely served their purpose, and worked hard to complete the hoisting work of large equipment.
