Machine room engineering cable arrangement method based on BIM

Abstract

The invention discloses a machine room engineering cable arrangement method based on BIM, which comprises the following steps: 1, numbering cabinets according to a sequence from small to large in a direction from a geosyncline to an adjacent row, and numbering holes leading to the outside of a machine room according to a cabinet numbering principle; 2, after cabinet numbering is completed, subtracting the maximum cabinet number from the minimum cabinet number, and determining the maximum difference value of the cabinet numbers; 3, calculating the maximum number of cables which are allowed to be arranged; 4, arranging and gathering all cables in the machine room; 5, formulating an arrangement sequence of different wire diameters; and step 6, completing the arrangement of all cables according to the cable arrangement basis. According to the method, corresponding staggered layer arrangement processing and the like are carried out in advance according to the intersection points of cable arrangement, so that intersection during cable arrangement is reduced, the aesthetic property of engineering cables in a geosyncline is improved, three-dimensional modeling is carried out on a cable wiring project by utilizing a BIM technology, implementation is carried out according to a model, and the method is more visual and rapid.

Description

Technical field [0001] The present invention relates to the field of BIM application technology, and in particular to a method for arranging cables in a trough of a machine room based on BIM. Background technique [0002] BIM (Building Information Modeling, that is, building information modeling) has a powerful three-dimensional design function, with the characteristics of three-dimensional visualization, collaboration and information extraction. All structural components in BIM are three-dimensional entities, providing complete information, and the three-dimensional display is intuitive and can be observed in real time, which can well detect the rationality of the structure layout and the characteristics of the detailed structure. The comprehensive application of BIM will greatly improve the degree of informatization of construction projects and have a huge impact on the progress of construction-related construction technology. [0003] In the fields of urban rail transit, high-s...

Problems solved by technology

However, the same as the first scheme, there is a lack of effective methods for checking intersections, mainly relying on the arrangement experience of technicians; in addition, the intersections generated by this scheme are difficult to adjust, and local intersections lead to repeated revisions of the scheme, which consumes a lot of time and effort. Still can't get a more reasonable layout plan after working hard

[0009] In order to make reasonable use of the layout space, it is necessary to plan in advance the number of rows of cables placed on the same section of the floor trough or cable rack, and reduce the overall height of the cables by increasing the number of rows to achieve the purpose of making full use of the layout space , increasing the number of columns will easily lead to an increase in the number of intersections, so it is necessary to screen and classify the cables in advance to avoid crossings while increasing the number of columns, which is impossible for the traditional cable arrangement scheme that relies on the experience of technicians. realized
