BIM-based transformer substation heating ventilation and water supply and drainage design method

Abstract

The invention relates to a BIM-based transformer substation heating ventilation and water supply and drainage design method. The method comprises the following steps: S1, constructing a transformer substation BIM three-dimensional model; S2, establishing a heating and ventilation BIM three-dimensional model according to the transformer substation BIM three-dimensional model; S3, establishing a water supply and drainage BIM three-dimensional model according to the transformer substation BIM three-dimensional model; S4, uploading the substation BIM three-dimensional model, the heating and ventilation BIM three-dimensional model and the water supply and drainage BIM three-dimensional model to a server; S5, performing three-dimensional model verification on the equipment on the construction site, and acquiring three-dimensional model modification information; and S7, modifying the heating and ventilation BIM three-dimensional model and the water supply and drainage BIM three-dimensional model according to the three-dimensional model modification information. Compared with the prior art, the BIM three-dimensional model is established, and the collision problem is effectively avoided, and double verification ensures that the three-dimensional model conforms to on-site practice, so that the construction quality and efficiency are effectively improved.

Problems solved by technology

[0002] The HVAC and water supply and drainage system of the substation have a great impact on the safety and life of the substation. If the HVAC system is blocked or leaks, it is easy to cause damage to the substation. The second water supply and drainage system is the fire protection part of the substation. Timely extinguishing in case of emergency and ensuring the safety of the substation. Therefore, the design requirements for HVAC and water supply and drainage are very high. If some functions and dimensions are not properly planned and laid out before the design and installation drawings are drawn, there may be pipeline elevations, Phenomena such as serious cross positioning, etc., which will affect the construction quality and construction efficiency

[0003] However, when HVAC and water supply and drainage are installed in substations, problems such as the inconsistency between the drawings and the actual site are often encountered, which brings great troubles to the installation and construction.

[0004] The existing technology uses two-dimensional plan for design, and the specific parameters cannot be reflected in the spatial position of each component in the model. The actual size of many key node equipment and components cannot be reflected, and construction collisions are prone to occur. Water supply and drainage cannot be realized in the two-dimensional plan. Accurately represent the relationship between the pipe network and the main transformer, and the collision between the water supply main pipe and the fire hydrant body in the vertical direction is easy to occur
