Description

technical field [0001] The invention relates to a drainage design method of a railway embankment, in particular to a horizontal, vertical and horizontal collaborative design method in the drainage design of a railway embankment. Background technique [0002] The railway subgrade should have a complete and unobstructed drainage system. The drainage design of the railway subgrade will quickly remove the ground water stagnant within the subgrade range and prevent the surface water outside the subgrade range from flowing into the subgrade range. Otherwise, poor drainage may directly endanger railway operations. Safety. In the past, the drainage design of railway subgrade was regarded as an auxiliary project, and it was only a guiding design, which was generally not reflected in the cross-sectional drawing of the subgrade. Only a schematic drawing of the drainage ditch was made on the plan view, so the design intention could not be accurately expressed, and construction could not...

Problems solved by technology

Under the new situation, the drainage ditch should not only be designed in detail on the cross-section to ensure that the cross-sectional size of the drainage ditch is reasonable and meet the drainage flow requirements, but also consider the influence and restrictions of the terrain and terrain, and choose a reasonable plane drainage layout position. Corresponding lines must be drawn, and at the same time, the vertical section of the drainage ditch must be finely designed to ensure smooth drainage. Therefore, the drainage design of the railway subgrade needs to comprehensively consider the three factors of horizontal, vertical and horizontal, overall planning, systematic and coordinated design. Without considering the coordinated design of the drainage ditch plane, longitudinal section and cross section, we can only design and add the drainage ditch on the subgrade cross section, determine the drainage slope by manual calculation, adjust the elevation of the ditch bottom, and then manually measure the lateral distance of the drainage ditch to calculate Draw the plane line position of the drainage ditch. The manual operation process of this method is cumbersome, and errors will inevitably occur, which makes the horizontal and vertical design unreasonable, and the work efficiency is extremely low. When the design of the drainage ditch is adjusted, related work such as drawing and engineering quantity calculation needs to be repeated. It is extremely error-prone, which brings great difficulties to engineering design review, seriously affects work efficiency and engineering quality, and cannot meet the needs of current railway construction.
