Embodiment

[0031] The Hefei Rail Transit Line 2 project starts from Changning Avenue Station and extends eastward along Changjiang West Road, Changjiang Middle Road, and Changjiang East Road to the terminal Dazhong Road Station. The starting and ending points are reserved for line conditions extending to both ends. The total length of the line is 27.764km, all of which are underground lines, with a total of 24 stations. The maximum station spacing of the line is 1.665km, located between Yulan Avenue and Shufeng Road; the minimum station spacing is 0.714km, located between Wanggang Avenue and Dazhong Road; The average distance between stations is 1.182 km.

[0032] The eight bid sections of the mechanical and electrical general contract that the applicant is responsible for construction include Longgang Avenue Station, Wanggang Avenue Station, Dazhong Road Station, and are located at the intersection of Changjiang Road and Wanggang Road, Longgang Road, and Dazhong Road. The three-station min...

Abstract

The invention belongs to the field of mineral substance cable installation and laying of mechanical and electrical installation inside subway stations, and specifically relates to a mineral substance insulated cable factory-like pre-configuration processing method based on a BIM technology. The method overcomes the defects of mineral substance insulated cables in the processing and site installation process. The method comprises the following steps: actual measurement of site three-dimensional space of a subway station, station modeling, full-profession pipeline optimization, mineral substance cable circuit arrangement sequence determination, mineral substance cable intermediate connector position determination, subsection cable work amount and total circuit work amount of mineral substances according to BIM model output, and two-dimensional information code information installation according to a mineral substance cable circuit. The labor cost and construction cost are effectively reduced, the material utilization amount of mineral substances is reduced, the construction period is reduced, a more reasonable construction method is provided, and simultaneously compared with original construction blueprint, the maintenance space is more sufficient, the overhaul and later operation maintenance are facilitated, and the method is high in practicability and beneficial for popularization.

Description

Technical field [0001] The invention belongs to the field of mineral cable installation and laying for electromechanical installation in subway stations, and in particular relates to a BIM technology-based industrial pre-distribution processing method for mineral insulated cables. Background technique [0002] With the development of the times, the construction boom of the subway has surged again after 2007. Especially in recent years, the development of subway construction has been booming. Nearly 30 cities have been completed or started construction. At present, the number of cities meeting the construction of subways has reached 50 cities. The construction of the times has been accelerated in an all-round way. Most of the electromechanical installations in subway stations are underground stations. Mineral cables are mainly used in subway projects because of their long life, large carrying capacity, excellent fire resistance, corrosion resistance, high temperature resistance, s...
