Problems solved by technology

The advantages of this control measurement method are: sufficient theoretical basis, small connection error of bid sections, and has been used in China; the disadvantage is: the full-line measurement data collection and adjustment must be completed to ensure the normal development of the work, the required construction period is long, and it is not restricted by the FIDIC standard Recognition (the country where the FIDIC standard is located only recognizes five-kilometer-level measurement control points), which is not conducive to promoting international business development

Embodiment Construction

[0017] like figure 1 Among them, a highway engineering control measurement method, it comprises the following steps:

[0018] Step 1, set up the RTK base station 1 with the design survey control point 3 as the starting site, and use the GPS mobile station 2 to collect the coordinates of the encrypted survey control point 4 to the design survey control point 3;

[0019] Step 2, taking design measurement control point 3 as the starting benchmarking point, surveying and drawing a complete leveling closed traverse; performing height difference adjustment calculation;

[0020] Preferably, the combined height measurement of the 4 encrypted control points in this section is completed, and the adjustment calculation is performed to ensure that the elevations of all encrypted control points in this section are closed. Stakeout using any point in the section can meet the accuracy requirements of the construction for the elevation .

[0021] Preferably, in a section of road control net...

Abstract

The invention relates to a highway engineering control measurement method; an RTK base station is adopted to be matched with a GPS mobile station to continuously measure control coordinates, and a level gauge is closed in a segmented mode, so that the construction progress is not affected, and errors are limited in segmented sections. The problems that an original full-line control measurement method needs a long construction period, is not accepted by the FIDIC standard and is not beneficial to promoting international business development are solved. The method has the characteristics of solving the measurement problems of low measurement level, short construction period and no measurement reference.

Description

technical field [0001] The invention belongs to the technical field of highway engineering measurement, and relates to a highway engineering control measurement method. Background technique [0002] At present, the domestic control survey in highway engineering mainly adopts the full-line control survey method: that is, the buried stone points of 500 meters to 1000 meters are laid out on the whole line, the GPS static observation method and the level control network are used, and the collected data are adjusted on the whole line. Errors are eliminated across the entire line. The advantages of this control measurement method are: sufficient theoretical basis, small connection error of bid sections, and has been used in China; the disadvantage is: the full-line measurement data collection and adjustment must be completed to ensure the normal development of the work, the required construction period is long, and it is not restricted by the FIDIC standard Recognition (the count...
