Embodiment

[0018] Embodiment: The observation method of this embodiment is used to provide an observation network type, which can save manpower by observing the base points of orbit maintenance together in the process of repeating the plane observation at the CPⅢ point (that is, the orbit control network point). And improve the observation efficiency.

[0019] Such as figure 1 As shown in , the direction indicated by the arrow is the direction of observation along the track, that is, the track maintenance base point and CPⅢ point are observed sequentially along the direction of observation of the track. The first station 1, the track maintenance base point 2, the track maintenance base point 3, the track maintenance base point 4, and the second station 5 are respectively located on track 12 or track 13; figure 1 , 2 As shown, CPⅢ point 6, CPⅢ point 7, CPⅢ point 8, CPⅢ point 9, CPⅢ point 10, and CPⅢ point 11 are all track control network points, and refer to a pair on both sides of trac...

Abstract

The invention relates to the field of surveying and mapping, in particular to a track maintenance base point plane measurement method. The method is characterized by including the following steps: an observing device is arranged at any one track maintenance base point which serves as a first station; at least three pairs of CP III points in the front and at least three pairs of CP III points in the rear of the first station along the track direction are observed; the first station, one track maintenance base point in the front and one track maintenance base point in the rear of the opposite side track along the track direction, and the prior track maintenance base point of apart track maintenance base points of the same side track are observed; and after observation is completed, the observing device moves to a second station to conduct observation, the second station is placed in the front of the side track opposite to the first station, and the first station and the second station are at a distance of two pairs of CP III points. The method has the advantages that all the track maintenance base points can be observed during track control (CP III).

Description

technical field [0001] The invention relates to the field of surveying and mapping, in particular to a method for measuring the plane of a track maintenance base point. Background technique [0002] The track maintenance base point is buried in the center of the junction of the two track slabs of the two adjacent pairs of CPⅢ middle lines, and one is laid every 60 meters or so. The buried position should be as close to the line centerline as possible, and the deviation from the line center should not be greater than 3cm. Uplink and downlink are buried separately. [0003] The traditional observation method of track maintenance base point is very similar to the observation method of track control network point (also called CPⅢ point), that is, the method of free station setting is used to observe three pairs of CPⅢ points before and after the station is set up, and finally carry out the whole section according to a section. Net adjustment. This traditional planar obser...
