Abstract

The invention discloses a method for determining tracks of arcs in road construction. The method comprises the following steps of: determining a reference value of a distance from a corner point of a road to a midpoint of an arc line for the design of a radius of turning circle, applying the reference to the determination of the track points of construction arc lines with the designed radii of turning circle within 10m, and applying the reference value to the determination of the track points of construction arc lines with the designed radii of turning circle greater than 10m. According to the method, the problem that the construction arc lines cannot be drawn by using center points due to obstacles when the arc lines with radii of turning circle prescribed by construction drawings are drawn on the sites in road construction can be solved.

Description

technical field

[0001] The invention relates to a method for determining arc tracks in road construction. Background technique

[0002] During the construction of living areas, factory areas, and municipal roads, the turning radius of the road is set, that is, the construction arc line that meets the design requirements is drawn, and obstacles such as houses, mounds, pits and ponds are often encountered and the impact of unfavorable environments. Because road construction and drawing arcs on paper are two different things, drawing arcs on paper can be completely based on mathematics and geometric theory, without any restrictions, and draw graphics according to the requirements in a standardized and accurate manner. The design of the turning radius in road construction is directly related to the circular arc theory, but it cannot be completely determined according to the method in the book to determine the circular arc that meets the design requirements. It is very difficult ...

Examples

Embodiment Construction

[0012] The technical solution will be described in detail below in conjunction with the accompanying drawings as an embodiment.

[0013] During municipal roads or other construction processes, the turning radius of the road is often marked on the construction drawings. In a flat and unobstructed terrain or an environment without obstacles, the method of determining the center point can be used to turn according to the design. The radius value can be used to draw the construction arc line by drawing the line. However, obstacles such as houses, mounds, and ponds are often encountered in actual construction. It is very difficult to use the arc line required by the center of the circle to draw the turning radius of the road. Some environmental conditions are absolutely impossible. Because it is impossible to determine the center point; use the following method for construction, you can find the position of the relevant trajectory points for drawing the arc line, and then draw the ...
