Bridge construction management system based on BIM

Abstract

The invention discloses a bridge construction management system based on BIM, and belongs to the technical field of bridge construction management. Key points of the technical scheme are as follows: the system comprises a design stage and a construction stage, the design stage is used for designing a scheme framework of a bridge. On the basis of the scheme framework, the framework is split to a construction installation unit to form a parameter table; a bridge BIM model is constructed, three-dimensional numerical finite element analysis is performede, engineering quantity calculation is performed on the bridge BIM model, cost data is generated, a part drawing is formed according to the bridge BIM model, and three-dimensional construction simulation is achieved according to the bridge model; in the construction stage, error checking is carried out through a point cloud model in combination with a bridge BIM model, and the earth-rock engineering quantity is calculated through an unmannedaerial vehicle and the BIM technology to obtain the accurate filling and digging quantity. According to the system, the technical barriers in the aspects of model delivery, information transmission and data interaction between design and construction are broken through, and an effective BIM collaborative application and communication mechanism between design and construction is established.

Description

technical field [0001] The invention relates to the technical field of bridge construction management, in particular to a BIM-based bridge construction management system. Background technique [0002] At present, BIM technology has been applied in full swing in the engineering construction industry, but there is still an embarrassing phenomenon that the design unit and the construction unit model their own models according to their needs, and it is still impossible to establish a set of BIM models based on the same BIM model between the design and construction units. The unique data transmission and information transmission mechanism, there is an isolated island of information transmission, which leads to the embarrassing situation that the design model is of little value and the construction unit repeats the modeling. As the key control engineering of highway projects, extra-large bridges have high social attention, complex technology, large engineering volume, and high inv...
