Embodiment

[0029] The scheme has been successfully applied to the construction project of the CRTSIII type slab ballastless track of the high-speed railway in the sixth section of the Zhengzhou-Xuan Passenger Railway Project, including pier numbers #154 to #215, of which 154-207 is a curve (straight and slow), and 207-215 is a straight line . By converting all the two-dimensional information (drawing information) of the high-speed rail construction project into a three-dimensional solid model, it integrates all the civil, material, construction and other information of the entire construction project into the model database, and engineers and technicians can complete the construction of the entire project. Curve elements, relevant space technical parameters, cross-sectional structure dimensions, coordinates and elevation information are accurately queried, and the technical route of project modeling is as follows: figure 1 shown.

[0030] Based on the BIM construction model, this projec...

Abstract

The invention discloses an application of a BIM technology to CRTSIII plate type ballastless track construction of high-speed railway. The application comprises the following steps of calculating related spatial technology parameters of a CRTSIII plate in a section according to a curve element table provided by a project; establishing a parameterized civil work and rebar model of the CRTSIII plate in the section according to a design drawing by utilizing a CATIA modeling platform, and finishing extraction of related parameters; performing site construction and design drawing check; performing three-dimensional technology disclosure of the site construction by cooperation of a project department to obtain related information of each construction section; performing construction progress management and material management by cooperation of the project department; assisting the project department to calculate a project amount based on BIM; and guiding the site construction based on a DELMIA construction simulation technology. According to the application, the BIM technology is applied to the plate type ballastless track construction management process of the high-speed railway for the first time, so that the design optimization, the construction process simulation, the three-dimensional technology disclosure and the like are realized, the working efficiency is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of building construction, in particular to an application of BIM technology in the construction of CRTSIII slab ballastless track of high-speed railway. Background technique [0002] At present, the average debt ratio of each bureau of China Railway Group is around 80%, the project profit margin is low, and the high-speed rail project suffers serious losses. There are many reasons for the loss, among which the low production efficiency caused by backward production technology is an important reason. [0003] As a digital tool applied to engineering construction management, BIM technology has a usage rate of more than 70% in North America and other developed regions, and the usage rate in the domestic construction industry is currently about 6%. This technology integrates relevant information of various projects through parametric models, and shares and transmits them during the whole life cycle of project planning, o...
