Jiujiang Petrochemical completed the topping of the chimney structure of the aromatics project

Sinopec News Network reported on July 19 that the 120-meter chimney of the Jiujiang Petrochemical Aromatics Project successfully achieved the topping of the concrete outer tube structure, marking the completion of the important node goal of the project
.

The chimney is a reinforced concrete structure with a total of 923.
3 cubic meters of concrete wall.
The construction of the barrel began on September 2, 2020.
The project adopts hydraulic lifting and turning form construction technology to embed support rods in the reinforced concrete wall.
As the main force bearing body, the hydraulic pressure of the perforated jack attached to the support rod drives the hydraulic lifting system to climb along the support rod
.

In order to ensure the construction quality and safety, reliability and control, the aromatics project department has coordinated and docked with the contractor many times, insisted on scientific organization, rationally optimized the construction plan, strictly controlled the construction quality, strengthened the management of the material inspection and approval system, and adhered to the weekly inspection, The monthly inspection and special inspection are combined to strengthen the measurement of the diameter and ellipticity of the formwork steel bars inside and outside the cylinder body, set up multiple settlement observation points for time-by-time observation, and make technical and operating procedures to ensure that the quality and appearance of the chimney meet the acceptance requirements

The project department always puts safety management in the first place, completes a comprehensive assessment of chimney construction risks in advance, formulates and implements risk control plans and safety precautions, organizes supervision, third-party supervision and construction parties to carry out special safety inspections from time to time, and pays attention to construction personnel Safety behaviors and equipment are in good condition, implement hard isolation at wrong time and position, strengthen ticket management for special operations and high-altitude operations, and ensure the safety and control of the construction process

Next, the project department will concentrate its efforts on the construction of the four-layer platform of the chimney wall, and urge and coordinate all parties involved in the construction to continuously strengthen safety and quality control, strive for internal and external beauty, and test data to meet the standard standards, and go all out to ensure that it will be achieved by the end of September.
