Abstract

The invention discloses a high-speed railway prefabricated box girder intelligent technology construction process based on a BIM technology, and the construction process comprises the following steps: carrying out the beam field planning on a digital topographic map through the combination of the BIM technology and the digital topographic map; the foundation of the beam field is reinforced, and box beam buttresses are arranged on the foundation of the beam field; a prefabricated box girder is formed; the prefabricated box girder is maintained and stored after being maintained; the prefabricated box girder is transported to a bridging area through a dumper, and the prefabricated box girder construction safety protection device is transported to the two sides of the dumper; in the process that a winch on the bridge girder erection machine hoists a prefabricated box girder, the prefabricated box girder construction safety protection device provides safety protection. And construction of the prefabricated box girder is completed through the bridge girder erection machine. When the prefabricated box girder is lifted and suddenly encounters strong wind weather, the prefabricated box girder can keep certain stability, and then construction safety accidents are avoided.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to an intelligent technical construction process of a prefabricated box girder of a high-speed railway based on the BIM technology. Background technique [0002] With the expansion of high-speed rail construction scale, the speed of construction is accelerated, the market is more and more open, and the competition is becoming more and more fierce. Prestressed simply supported box girder is one of the indispensable components of high-speed railway, and its quality is directly related to the service life of the bridge. Therefore, attention is paid to the construction management of prefabricated box girder, and the study of construction control measures for prefabricated box girder has become an important part of the industry. direction of active exploration and research. [0003] Patent No. 201811287053.0 discloses the construction method of prefabricated box girder. Duri...
