This is the first victory for Dalian Branch’s Guangxi petrochemical project to achieve a closed loop of design, procurement and construction. It is also a successful demonstration of PetroChina’s first modular construction of pipe gallery steel structures. It is also a breakthrough for PetroChina in the new construction model of “factory prefabrication + modular construction”. It is reported that there are a total of 181 pipe gallery modules in the Guangxi Petrochemical Chemical Process and Thermal Pipeline Network. The first module to be hoisted this time is one of the No. 4 pipe gallery modules. The module is a 4-axis, two-frame structure, 27 meters long, 6 meters wide, 9 meters high, and weighs 58 tons. “The "factory prefabrication + modular construction" construction model converts traditional on-site operations into factory production by manufacturing and installing pipe gallery steel structures and process pipes, achieving "one installation site + four factories (module manufacturing plant, steel structure manufacturing plant, pipeline anti-corrosion plant, concrete structure manufacturing plant)" synchronized operations. dd improves the efficiency of construction operations, ensures smooth roads during the construction process, reduces the risk of high-altitude operations, and is beneficial to improving construction safety, improving quality, promoting civilized construction, and improving the working environment.
The total length of the chemical process and thermal pipeline network project is 9.78 kilometers, 43,652 cubic meters of concrete, 2,587 concrete columns, 25,364 tons of steel structure, 380 kilometers of process pipelines, 550,000 inches of pipe welding, and 44 kilometers of electrical bridges. The overall structure of the pipe gallery is "steel on top and concrete on the bottom", that is, relative to the floor elevation, the part above 6 meters is the steel structure, and the part below is the concrete column. The No. 4 pipe gallery numbered 4#-3-1 module accepted this time is a 4-axis, two-frame structure, 25 meters long, 6 meters wide, 9 meters high, and the module weight is 57.8 tons. The picture shows that in the modular construction of the pipe network, the civil cup foundation is poured on site, and the factory prefabricated concrete columns arrive. The steel structure is "modularized + integrated" at the precast site. At the same time, process pipes, cable trays, etc. are integrated into the structural modules. After the modules are completed at the prefabricated site, they are transported to the construction site by axis trucks and hoisted into place using large crawler cranes. Ultimately, "one construction site, multiple factories" will be realized, multiple connecting processes will be transformed into parallel processes, and the construction cycle will be significantly shortened.
