Sinopec News Network reported on July 16 that the last weld of the Shandong Weifang 300,000-ton/year high-end polypropylene project undertaken by the No.
10 Construction Company of Refining and Chemical Engineering was qualified, marking that the underground pipe network project of the project has successfully achieved the main completion target
.
It is understood that the total amount of pipeline installation in the underground pipeline network project of Weifang high-end polypropylene project is 15,000 inches in diameter, which is faced with many unfavorable factors such as complex geology and harsh construction conditions
.
Since the start of the underground pipe network project, the Weifang Project Department of Ten Construction has been actively cooperating with the owner, supervision, design and other units to implement the underground pipe network engineering drawings and materials in place, and fully connect the key and difficult problems faced in the construction process.
The project department gave full play to the advantages of teamwork, broke the traditional method of excavating, installing, and backfilling the underground pipe network, and implemented the “four-concentration” mode of centralized prefabrication, centralized excavation, centralized installation, and centralized backfilling to improve the underground pipeline network.
The construction efficiency was nearly 20 days ahead of the original plan, which allowed time for professional construction such as ground hardening, steel structure, and equipment
.
In the construction of the underground pipeline network, the project department has overcome the continuous heavy rainfall since the beginning of summer in Weifang, and carried out comprehensive and three-dimensional safety risk investigation at each construction site on site, and successively carried out prevention of earth collapse, lightning protection, and temporary Professional safety emergency drills such as electricity use, lifting and hoisting will make every effort to improve the safety protection capabilities of employees participating in the construction, so as to "identify major risks, eliminate major hidden dangers, and prevent major accidents", and make every effort to build safety control and defense lines
.
The project department adopts high standards and strict requirements on the welding quality of underground pipe networks, and minimizes the frequency of various construction quality hazards
.
With the hard work of the construction employees, the pass rate of underground pipe network welding for one-time flaw detection reached more than 98.
