Embodiment Construction

[0023] A forward design method of port ventilation system based on BIM technology, the specific steps are as follows:

[0024] The first step is to create a ventilation design BIM model template according to the actual use of the building, air quality requirements, local climate conditions, and noise requirements of the surrounding environment;

[0025] In the second step, based on the BIM model template in the first step, combined with the upstream civil engineering and structural professional BIM models, the ventilation design BIM basic model is integrated;

[0026] The third step is to calculate the air volume and wind resistance for the ventilation design BIM basic model obtained in the second step according to the design requirements and specification standards;

[0027] The fourth step, according to the calculation results of air volume and wind resistance obtained in the third step, carry out ventilation scheme design, airflow organization design, and determine the vent...

Abstract

The invention discloses a port ventilation system forward design method based on a BIM technology. The method comprises the following specific steps that a ventilation design BIM model template is created; a ventilation design BIM basic model is integrated; the air volume and the air resistance of the ventilation design BIM basic model are calculated; a ventilation system scheme is determined; design and model selection of a fan are carried out; an air pipe, an air port, an air valve, an air pipe support hanger and a fan foundation are designed; and all professional BIM models are coordinated,optimized, audited and approved, and finally the ventilation system construction stage design BIM model is formed. The three-dimensional forward design of the ventilation system is realized by utilizing the three-dimensional model form of the BIM technology and strong information integration capability, so that the design becomes more vivid, the phenomena of mistakes, omissions, collisions and missing are reduced, and the construction disclosure becomes vivid.

Description

technical field [0001] The invention relates to the technical field of port ventilation system design, in particular to a forward design method for port ventilation systems based on BIM technology. Background technique [0002] The ventilation system is a conventional and effective method to improve the air quality in the operation area, especially in the port operation area where there is a lot of dust and the air quality is poor, so it is particularly important to equip the ventilation system. However, the current design of the ventilation system mainly relies on CAD for 2D construction drawings. It is difficult to coordinate among various disciplines. It is difficult and there are many problems in the construction. Therefore, there is an urgent need for a method to solve the above problems. Contents of the invention [0003] The present invention aims to solve the deficiencies of the prior art, and provides a forward design method of port ventilation system based on B...
