For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0034] The present invention will be described in detail below in conjunction with specific implementation modes.

[0035] In some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, this solution provides a method for arranging a track control network of a track engineering, comprising: Establish a virtual construction environment for rail engineering, which is a simulated construction environment with the plane control network nodes and line leveling base points arranged; Evaluate the track control network layout environment based on the virtual construction environment; When the evaluation results meet the layout conditions, the track control network will be laid out along the track.

[0036] In some possible implementations of the present invention, evaluating the layout environment of the track control network specifically includes: Based on the virtual construction environment, the arranged plane control network nodes and line leveling base points are accurately re-measured; and / or, based on a virtual construction environment, measuring settlement and deformation along the track; And / or, based on the virtual construction environment, re-survey the plane and elevation positions along the track.

[0037] Specifically, this embodiment provides an implementation method for evaluating the layout environment of the track control network. Before the track control network is laid out, the layout environment of the track control network needs to be evaluated. The present invention uses computer technology to achieve the evaluation of the layout environment of the track control network in a virtual environment based on the relevant data that has been surveyed, thereby providing a data basis for the layout of the track control network.

[0038] In a possible embodiment, before the track control network (CPⅢ) is built, a comprehensive re-survey of the precision measurement network should be carried out to ensure the connection of the track control network (CPⅢ), that is, the arranged plane control network nodes and line leveling base points should be accurately re-surveyed.

[0039] In a possible embodiment, the track control network (CPⅢ) measurement should be carried out only after the settlement and deformation of the offline engineering meets the specification requirements and the track laying condition assessment is passed, that is, the settlement and deformation along the track are measured.

[0040] In a possible embodiment, the completed offline project should be re-surveyed in plane and elevation before track laying to deal with the error limit caused by construction layout in advance and lay a good foundation for track laying, that is, re-survey the plane and elevation along the track.

[0041] In some possible implementations of the present invention, the arrangement of a track control network along the track specifically includes: Based on the virtual construction environment, a pier 10 arranged along the extension direction of the track is obtained; Based on the pier 10, the bridge 30 fixed support 20, the bridge 30 and the crash wall 40 are determined, the bridge fixed support 20 is connected to the pier 10, the bridge 30 is connected to the side of the bridge fixed support 20 away from the pier 10, and the crash wall 40 is set on the bridge 30 along the extension direction of the track; A pair of track control network nodes are arranged on the surface of the crash wall 40 away from the bridge 30, wherein the distance between the track control network node and the end surface of the bridge 30 is within a set distance range; Repeat the above steps to obtain N track control network nodes, where N is a positive integer greater than or equal to 2; Generate a track control network based on all track control network nodes.

[0042] Specifically, this embodiment provides an implementation method for arranging a track control network along the track. By acquiring the features of the pier 10, the fixed support 20 of the bridge 30, the bridge 30 and the crash barrier 40 during the track construction process in a virtual environment, the layout of the track control network nodes in different environments during the track laying process is realized, making the virtual environment closer to the actual situation for the layout of the track control network nodes, improving work efficiency while ensuring accuracy.

[0043] In some possible implementations of the present invention, the arrangement of a track control network along the track specifically includes: When the bridge 30 is a simply supported beam, a first length parameter of the simply supported beam is obtained; When the distance of the simply supported beams identified by the first length parameter is less than or equal to the first set length, a pair of track control network nodes are set at the distance between every two piers 10; In the case where the distance of the simply supported beam identified by the first length parameter is greater than the first set length, a pair of track control network nodes are set at the distance of each pier 10.

[0044] Specifically, this embodiment provides another implementation method for arranging the track control network along the track. When the bridge 30 is a simply supported beam, the track control network nodes are arranged in combination with the length parameters of the simply supported beam.

[0045] In a possible embodiment, for a 24m or 32m simply supported beam, a pair of CPⅢ points is arranged for every 2 holes, and the distance between two adjacent pairs of CPⅢ points is about 64m (32m+32m), 56m (24m+32m) or 48m (24m+24m).

[0046] In a possible embodiment, for a 40m simply supported beam, a pair of CPIII points is arranged in each hole; for a continuous 24m simply supported beam, a pair of CPIII points may also be arranged in every three holes according to actual conditions.

[0047] In some possible implementations of the present invention, the arrangement of a track control network along the track specifically includes: When the bridge 30 is a common continuous beam, a second length parameter of the common continuous beam is obtained; When the length of the common continuous beam identified by the second length parameter is less than or equal to the second set length, the track control network node is arranged at the position of the crash wall 40 corresponding to the fixed support 20 of the bridge 30; When the length of the ordinary continuous beam indicated by the second length parameter is greater than the second set length, the track control network node is arranged at the position of the fixed support 20 of the bridge 30 corresponding to the crash wall 40, and the first supplementary layout points of at least two ordinary continuous beams, and the first supplementary layout points are located between 50m and the second set length, and the second set length is greater than 50m.

[0048] Specifically, this embodiment provides another implementation method for arranging the track control network along the track. When the bridge 30 is a common continuous beam, the track control network nodes are arranged in combination with the length parameters of the continuous beam.

[0049] In a possible embodiment, the second length parameter is greater than the first length parameter, and the second set length is greater than the first set length.

[0050] In a possible embodiment, for ordinary continuous beams, CPⅢ should be preferentially arranged above the fixed end.

[0051] In a possible embodiment, for ordinary continuous beams with a span of more than 80m, one or several pairs of CPⅢ points should be arranged as evenly as possible at intervals of 50 to 80m in the middle of the span. When using or re-measuring the CPⅢ points in the span, try to ensure that they are the same as the external environment for measurement. The entire continuous beam section should be reviewed before use.

[0052] In some possible implementations of the present invention, the arrangement of a track control network along the track specifically includes: When the bridge 30 is a special bridge structure, the structural parameters and the third length parameter of the special bridge structure are obtained, where the structural parameters at least include the structural form, span and material of the special bridge structure, and the special bridge structure at least includes a long-span continuous beam, a suspension bridge, an arch bridge and a cable-stayed bridge; determining a third set length for the particular bridge structure based on the structural parameters; determining the number and positions of the second supplementary arrangement points of the special bridge structure based on the third length parameter and the third set length; Based on the second supplementary layout point, the track control network nodes of the special bridge structure are supplemented and arranged.

[0053] Specifically, this embodiment provides another implementation method for arranging the track control network along the track. When the bridge 30 is a special bridge structure, the track control network nodes are supplementarily arranged according to the structural parameters and the third length parameter of the special bridge structure.

[0054] In a possible embodiment, the third length parameter is greater than the second length parameter, and the third set length is greater than the second set length.

[0055] In a possible embodiment, the points are arranged according to the CPⅢ point pair arrangement requirements and spacing, taking into account the different beam span structural forms, spans, and materials. The spacing between adjacent point pairs can be appropriately increased, but the maximum does not exceed 90m.

[0056] In a possible embodiment, no CPⅢ point may be buried in the span of a continuous beam within 80 meters; a pair of CPⅢ points should be buried in the span of a continuous beam between 80 and 120 meters; and two pairs of CPⅢ points should be buried in the span of a continuous beam between 120 and 180 meters.

[0057] In a possible embodiment, when a CPⅢ point pair is buried in the mid-span, the CPⅢ point should be buried at the fixed end on the same continuous beam. The embedded parts of this CPⅢ point should be flush with the top surface of the crash barrier 40, and a special connecting device should be used to facilitate the installation of the total station.

[0058] In a possible embodiment, when two or more pairs of CPⅢ points are buried in the mid-span of the continuous beam, the CPⅢ points of the left and right lines should be on the same observation line of sight.

[0059] In some possible implementations of the present invention, the arrangement of a track control network along the track specifically includes: When the bridge 30 is within the station area, obtaining the platform eaves of the station area; Based on the bridge 30 and the station area, determine the intersection area of ​​the platform eaves and the crash barrier 40; Based on the intersection area, the track control network nodes arranged on the platform eaves and the crash barrier 40 are determined.

[0060] Specifically, this embodiment also provides an implementation method for arranging the track control network along the track. When the bridge 30 is within the station area, since the clearance between the protective wall in the platform beam section and the bottom of the platform beam cannot meet the leveling measurement requirements, the CPⅢ points within the station area need to be set on the platform eaves, and the remaining sections are also set on the protective wall of the fixed support 20 of the bridge 30 to ensure the stability of the marking points.

[0061] In a possible embodiment, the CPⅢ points in the station area and the junction area should also be arranged in pairs, generally about 50 to 70 meters apart. In some special cases, the shortest distance between adjacent points is not less than 40 meters and the longest is not more than 80 meters. The mileage difference of the same point pair is not more than 3 meters, and the CPⅢ points should be arranged at roughly the same height.
