Technical Field

The invention relates to the field of BIM modeling, in particular to a BIM-based mountain building electromechanical pipeline construction method.

Background

The relief slope in mountain region building place is big, builds according to the mountain for reducing earthwork excavation, and mountain region building often has the floor subregion, and there is the difference in height on the ground in the continuous department of different subregion floors, even has the difference in height on the same floor ground. The mountain building is perfectly fused with mountain forest, and the general layer height is lower. Due to the characteristics of the mountain land building, the building structure is complex, the clearance is narrow, and great difficulty is brought to the electromechanical pipeline construction of the mountain land building. The conventional electromechanical construction is based on two-dimensional drawings of a design institute, some design defects and leaks cannot be found in time, and the subsequent problems that the reserved embedded pipe is mistaken and the electromechanical pipeline cannot be constructed and reworked are caused. Common problems are as follows: the method is characterized in that the preset embedded casing is lost or collides with a beam, a vertical pipe cannot vertically penetrate through corresponding floors, the system is difficult to communicate with the building with the height difference due to the collision with a structure and electromechanical pipelines or the system is too much turned over to influence the system function, the construction is performed according to the original design, the construction sequence is disordered, the pipelines are too much turned over, the arrangement is disordered, the effect is poor, and the use clearance is difficult to guarantee.
