Construction engineering quantity calculation method of underground excavation metro stations and running tunnels

Abstract

The invention provides a construction engineering quantity calculation method of underground excavation metro stations and running tunnels. According to the method, an underground excavation metro station and running tunnel three-dimensional informationized model is constructed by means of BIM software, the attribute set of the model is settled; an engineering quantity statistic database is established, and the engineering information data rules among the model, the attribute set and the database are created; association between the model and object attributes is realized; and corresponding engineering quantities of the metro stations and running tunnels are automatically calculated and are automatically summarized, so that an engineering quantity calculation list of the metro stations and running tunnels can be obtained. With the method adopted, the efficiency of engineering calculation can be greatly improved. The method has the advantages of quickness and accuracy.

Description

Technical field: [0001] The invention belongs to the information-based construction technology of excavated subway station interval tunnels, and mainly relates to the construction field of underground excavated subway stations and interval tunnels, in particular to a method for calculating the construction quantity of underground excavated subway station interval tunnels, and specifically relates to a method based on BIM technology Calculation method of construction engineering quantity for submerged subway station interval tunnels. Background technique: [0002] Urban subway construction has the characteristics of many stations, long lines, wide coverage, large scale, high investment, long construction period, large amount of data and information, etc. In the process of subway construction, engineering quantity calculation is the most critical part of project cost control , and at the same time it is the most boring and cumbersome process. It is not only time-consuming, but...

Problems solved by technology

The user must input data into the computer while flipping through the drawings while considering the deduction relationship, and must still list the calculation expressions of the engineering quantities of each component. The calculation is very cumbersome, and sometimes errors can be found through review and other means, but Since the change of the local engineering quantity will cause the change of the corresponding summary quantity, which will cause the readjustment of the summary table, the error of this method will cause a large repair cost

Therefore, although this method improves the user's calculation efficiency to a certain extent, it does not fundamentally relieve the cumbersome labor of the calculation personnel.
