Automatic mapping method for embedded part of double-block ballastless track simply supported beam bridge floor

Abstract

The invention discloses an automatic drawing method for an embedded part of a double-block ballastless track simply supported beam bridge floor. The method comprises the steps: 1, performing drawing parameterization on all parts of an embedded part design drawing; 2, designing a layout scheme on the bridge and automatically counting the number of embedded parts; 3, performing parameterized drawingof a complete set of drawings based on programming language. Beneficial effects are that each calculation drawing module is embedded into an AutoCAD system based on a programming language, and an AutoCAD man-machine interaction design process is pertinently expanded by adding menu bars required by designers, so as to realize automatic drawing of a design drawing of the CRTSI type double-block ballastless track embedded part of the simply supported beam section of the high-speed railway. According to the method, the drawing efficiency and precision are greatly improved, manual calculation is avoided, the distribution diagram of the simply supported beam bridge deck embedded parts with different lengths can be drawn quickly and accurately, the labor intensity of designers is reduced, and the drawing parameterization, automation and informatization levels are enhanced. The automatic mapping function is achieved, and reference can be provided for modernization and intelligent constructionof railway design.

Description

technical field [0001] The invention relates to the field of ballastless track design for high-speed railways, in particular to an automatic drawing method for embedded parts of a double-block ballastless track simply supported beam bridge deck. Background technique [0002] CRTS Ⅰ double-block ballastless track is one of the main types of ballastless track for high-speed railways in my country. Due to its mature technology, low construction cost, rich operating experience, and strong structural adaptability, it has been widely used in Hangshaotai, Changjinghuang, Xicheng, Wu It has been widely used in bridge sections of Guangzhou and other high-speed railway lines. It is mainly composed of 60kg / m rail, WJ-8B type fastener, SK-2 type sleeper, concrete track bed plate, base plate and other structures. [0003] The embedded part of the bridge deck is an important structure to ensure the close connection between the ballastless track of the high-speed railway and the bridge str...

AI Technical Summary

Problems solved by technology

The gap between the slabs of the CRTS I double-block ballastless track track bed is 100mm. Therefore, for non-standard simply supported beams, the standard slab cannot meet the design requirements, and non-standard length track bed slabs need to be designed according to the situation.

After the length of the double-block ballastless track slab changes, the distance between the fasteners, the position of the sleeper and the distribution of the embedded parts must be redesigned. Multiple checks and proofreadings greatly increase the workload of designers
