by On December 8, with the 320 ton crawler crane slowly lifting 8.9 meters high The Precast Pier Column with a weight of 65 tons stably landed at pier 334.
The first expressway project in Zibo has entered the stage of assembly.
Zibo has entered a new journey of bridge assembly construction.
Since entering the site, the project team has scientifically and orderly promoted the project construction, successively conquered many nodes and helped Zibo people realize the “elevated dream” as soon as possible ▲ drilling of the first pile ▲ pouring of the first prefabricated pier column ▲ pouring of the first prefabricated box girder editor in charge: Chen Honglei checked by: Li Helei, Chen Zicheng (Trainee) reviewed by: Qi Xinxin welcome.
At the construction site, the workers prepare cement mortar on site and test the relevant parameters of cement mortar to ensure the quality of column grouting and sleeve grouting.
Vertical observation points are set on site to ensure the verticality and hoisting accuracy of column components By means of “building blocks”, the 38 grouting sleeve openings at the lower end of the column and the 38 embedded reinforcement above the bearing platform are tightly connected and perfectly connected to achieve “millimeter level” assembly accuracy.
The so-called fabricated bridge is the column, cap beam The box girder and other components are prefabricated in the factory workshop and then transported to the site.
The prefabricated pier column hoisted this time adopts the prefabricated assembly construction process connected by grouting sleeve, which has strict requirements on the accuracy of components.
The pier column is overturned, installed and leveled.
The hoisting of the first prefabricated pier column of the whole line of Zibo expressway project is the first fabricated bridge project in Zibo.
The bracket pier column is trial assembled Installation and fine adjustment after completion of grouting ▲ hoisting process of Precast Pier Column (slide left and right) the standardized design, factory manufacturing, assembly construction and information management adopted by the project are the most advanced construction methods in China, which are the first in the construction of Zibo Municipal project.
Large hoisting equipment is used to assemble them like “building blocks”.
The pier column components are prefabricated in the factory and transported to the construction site for hoisting and installation ▲ the grouting sleeve pier column is stored at the bottom of the pier column, and the contact surface of the bearing platform is roughened.
Zibo urban expressway network construction project is an important link in the “two rings and five rays” plan of Zibo City, which is connected in series with the “three cities” intensively built by Zibo City “Five districts” have entered the “elevated era” in Zibo At the same time, improve the city’s energy level and integrated development level.
