Problems solved by technology

Due to the numerous construction procedures and complex technological process of urban rail transit, the construction schedule table prepared by the designers cannot accurately guide the construction process based on the existing theoretical knowledge and past experience of construction organization estimates, and there are often problems such as delays in the construction period. Seriously affect the progress and quality of the project; when the construction personnel carry out construction according to the construction documents, they can only make a general plan for the construction process, cannot form an intuitive understanding of the construction scene, and fail to find problems in the construction process in time, resulting in people, objects, The waste of money has greatly increased the construction cost of urban rail transit vehicle bases; new construction personnel can enter the site after passing the systematic theoretical knowledge training. The clear, intuitive and visual learning method of the construction process of each sub-project is particularly important

Embodiment Construction

[0033] Such as figure 1 As shown, the VR and BIM-based urban rail transit vehicle base modular construction simulation method of the present invention comprises the following steps:

[0034] Step 1. Establish a modular database, the process is as follows:

[0035] Step 101, establish a modular environment database: through on-the-spot exploration and querying local hydrological data manuals, use the BIM platform to construct a modular environment database of the environment in which the urban rail transit vehicle base is located. The modular environment database consists of a natural environment model Composed of a geological environment model, the natural environment model includes terrain, landform, hydrological conditions and climate conditions, and the geological environment model includes soil structure and soil quality;

[0036] It should be noted that the purpose of establishing a modular environmental database is to consider the actual environmental factors and combin...

Abstract

The invention discloses a VR and BIM-based modular construction simulation method for urban rail transit vehicle bases, comprising steps: 1. Establish a modular database, 101, establish a modular environment database, 102, establish a modular basic material database, 103 104. Establishing a database of modular construction equipment; 2. Constructing a three-dimensional construction scene model; 3. Selecting a modular construction simulation method for the urban rail transit vehicle base and performing modular simulation construction on the urban rail transit vehicle base. The invention determines the optimal construction process and project progress, and then determines the construction plan of the sub-item project of the urban rail transit vehicle base, dynamically simulates the construction process, provides a clear and intuitive learning mode for the construction personnel, and helps the construction personnel to discover The deviation between the construction process understood by oneself and the optimal construction process should be adjusted in a timely manner to effectively ensure the construction progress of the vehicle base.

Description

technical field [0001] The invention belongs to the technical field of modular construction simulation, and in particular relates to a VR and BIM-based modular construction simulation method for an urban rail transit vehicle base. Background technique [0002] The urban rail transit vehicle base is the place for the preparation, maintenance and repair of subway vehicles, and it is an important guarantee for the operation safety of the subway network. Good engineering construction quality is the premise to ensure that the urban rail transit vehicle base is put into use, and the direct factor that determines the quality of engineering construction is the construction process. Due to the numerous construction procedures and complex technological process of urban rail transit, the construction schedule table prepared by the designers cannot accurately guide the construction process based on the existing theoretical knowledge and past experience of construction organization estim...
