Turnout track lining construction method based on BIM technology

Abstract

The invention relates to a turnout track lining construction method based on a BIM technology. The turnout track lining construction method comprises the steps: (1) carrying out three-dimensional modeling according to a drawing and the surrounding environment; (2) performing construction organization design, and making a construction scheme; (3) carrying out animation production according to the turnout track lining operation process and the construction scheme; (4) performing construction according to the construction scheme determined by the construction simulation animation; (5) monitoringwhether the actual construction condition deviates or not; if no deviation exists, skipping to the step (7); if the deviation exists, pausing the construction and entering the next step, wherein the deviation comprises but is not limited to the following construction conditions: 1, construction period delay caused by substandard operation conditions, influence of natural weather and misoperation of constructors; 2, construction quality dissatisfaction; and 3, improper arrangement of labor organization; (6) performing construction organization design again, and returning to the step (3); and (7) completing construction and filing data. According to the method, the construction efficiency and accuracy are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of railway engineering, and relates to a BIM technology-based construction method for turning a turnout. Background technique [0002] As the weakest part of the track line, the turnout often requires track construction due to lateral displacement or poor direction. [0003] The construction of turnout shifting mainly depends on the use of tools such as track pullers, strings, and steel rulers by technicians, and the cooperation between construction personnel. Generally, the amount of a single channel is about 0-40mm. The construction requirements are fine, and the operating conditions and quality requirements are relatively high. It is easy to cause the construction to fail to meet the requirements because the construction personnel are not familiar with the process or improper operation. [0004] Building information modeling (BIM) technology started relatively late in domestic research, but its applicati...

Problems solved by technology

However, the BIM technology in the prior art is used in engineering construction. Generally speaking, it is only to make construction animations, and then determine the construction plan at one time, but does not consider that the original construction plan will become unfeasible due to unexpected factors in actual construction.

The construction process of turnout is complex, the operating conditions are relatively strict, and the quality acceptance requirements are also high. Moreover, the construction environment of the railway site is harsh, and uncertain problems are likely to occur during construction. This will not only delay the construction progress, but also increase the construction cost.
