Embodiment 1

[0066] Example 1: Collision of fire pipes and exhaust pipes;

[0067] see picture , it can be seen from the BIM model that there is a collision between the fire pipe 1 and the exhaust pipe 2, and the position 3 shown in the circle is the collision node between the fire pipe 1 and the exhaust pipe 2, and the collision position is recorded on the plan drawing And solutions, in this way, only need to lower the elevation of the fire water pipe before the fire water pipe meets the exhaust pipe to avoid conflicts, and can be avoided during the construction process.

Embodiment 2

[0068] Example 2: Collision between exhaust pipe and cable tray.

[0069] see Figure 4 shown, from Figure 4 It can be seen that there is a collision between the exhaust pipe 4 and the cable tray 5, and the collision occurs at the position 6 (collision node) indicated by the circle in the figure. Through construction experience, it can be considered that the elevation of the air duct here can be lowered by 200mm to avoid collision. And record the location of the collision point on the plane construction drawing, and notify the air duct processing team that during the air duct processing, the air duct elbow at the blue-green junction should be properly adjusted to meet the elevation of the air duct and avoid collision with the bridge frame. In this way, we save the waste of labor and materials that may be caused by rework.

[0070] Through the BIM collision detection analysis, the construction plan was optimized, the friction between various disciplines was reduced, the phe...

Abstract

The invention belongs to the technical field of electromechanical device installation and discloses a complex pipeline collision optimization method of subway electromechanical engineering. According to the method, three-dimensional bus interface module (BIM) software is used for establishing different professional virtual BIM models which are consistent with completed engineering and then output to three-dimensional collision software for establishment of a combined three-dimensional collision model for collision analysis, collision nodes are then processed and optimized, and then decorative texture mapping and animation roaming are carried out on the combined, analysed and processed three-dimensional collision model without the collision node problem through 3D - MAX software, and therefore collision optimization of complex pipelines of the subway electromechanical engineering is achieved. According to the complex pipeline collision optimization method of the subway electromechanical engineering, the BIM technology is utilized to solve the problem that collision of various complex pipelines causes construction ceasing during electromechanical installation, reasonable planning and utilization of electromechanical pipeline equipment and the like are achieved by means of the optimized design, construction waste is reduced, construction time is shortened, working efficiency at site is improved greatly, and initial investment of a proprietor is reduced.

Description
