Abstract

The invention relates to the technical field of the rail construction engineering, in particular to a method for adjusting control benchmark point of a rail by means of approximate adjustment. The method is characterized in that two ends of a point to be determined are added into a known traverse point to form an echoed lead according to a point to be determined of a known point lofting control benchmark point, an actual-measurement corner and side relationship and a theoretical corner and side relationship of the echoed lead are compared, the position of each point to be determined is regulated, so that a point location error of the point to be determined falls within the required range, and therefore, the point to be determined is determined as a control benchmark point. According to the method disclosed by the invention, all control benchmark points are related to form a new rail control lead, manual errors in the lofting process are regulated, the precision of a rail control point is improved so as to improve the accuracy of a rail control benchmark and the rail status quality, so that a train can stably and quickly operate, the method is simple to operate, high in precision and high in engineering efficiency, can be completely applied to the rail traffic engineering construction, and is safe and reliable.

Description

[technical field]

[0001] The invention relates to the technical field of track construction engineering, in particular to an approximate adjustment method for adjusting track control base points. [Background technique]

[0002] As we all know, in recent years, the field of rail transit in my country has developed rapidly. Urban rail transit has become the first choice for most people to travel because of its convenience and punctuality. At the same time, people have higher and higher requirements for the safety of trains and the comfort of travel. . The track-laying standard is a high-standard track laying control point, and its accuracy is directly related to the accuracy of the entire railway track construction, and is also closely related to the safety in the process of putting it into use in the future. It is difficult to adjust the track engineering once it is positioned. The process of track engineering survey mainly includes re-measurement of construction control poin...
