Problems solved by technology

At present, in road construction projects, there are mainly the following shortcomings in the division of tenders in the construction scope: (1) the construction scope is defined by language description or directly using the road outline in the design drawings, which cannot clearly and intuitively display the tenders; Section division rules are too simple and inflexible, making it impossible to adjust adaptively according to complex construction scenarios; (3) The landmark section at the end of the road construction is inconsistent with the actual outline of the road, resulting in insufficient or exceeding the construction scope; (4) Multiple At the intersection of roads, it is impossible to determine the ownership of the tender in the intersection area

Embodiment 1

[0060] see figure 1 , the present embodiment proposes a method for determining road construction bids, including:

[0061] S100: Obtain a road plan, and extract a center line of a target road from the road plan.

[0062] The road plan may include a two-dimensional top view of the road drawn by any existing drawing software, such as a CAD plan. It can be understood that the center of the road surface entity in the road plan usually includes a center line, and the extension direction of the center line is consistent with the extension direction of the road surface entity. Furthermore, a plurality of chainages are usually arranged in sequence on the center line, which are used to represent information such as the elevation of the road surface.

[0063] S200: Divide the centerline into a plurality of unit line segments according to the stake numbers marked on the center line; wherein, each of the unit line segments is a part of the center line between two connected stake numbers...

Abstract

The invention provides a section determining method and device for road construction. The method comprises the steps of obtaining a road plane graph, and extracting a center line of a target road from the road plane graph; dividing a center line into a plurality of unit line segments according to stake numbers marked on the center line; each unit line segment being a part, between two connected stake numbers, in the center line; generating a unit range frame based on each unit line segment; each unit range frame being used for representing a road construction range corresponding to the corresponding unit line segment; adjusting the unit range frames, so that overlapping and gaps do not exist between every two adjacent unit range frames, and the unit range frames cover corresponding areas of the target road; and determining the section of the target road according to all the adjusted unit range frames.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a method and a device for determining bid sections of road construction. Background technique [0002] Bid section refers to the section divided according to the construction bidding during the construction of long line construction projects such as highways and railways, and each section is constructed by the corresponding bid-winning unit. At present, in road construction projects, there are mainly the following shortcomings in the division of tenders in the construction scope: (1) the construction scope is defined by language description or directly using the road outline in the design drawings, which cannot clearly and intuitively display the tenders; Section division rules are too simple, lack flexibility, and cannot be adjusted adaptively according to complex construction scenarios; (3) The landmark section at the end of the road construction is inconsistent with ...
