Abstract

The invention provides a dam side boundary control method based on a GPS-RTK surveying and mapping instrument and a programmable calculator. The dam side boundary control method comprises the steps ofdam side boundary design element input, SUB-BX program programming, GPS-RTK surveying and mapping, calculation of a current actual side boundary value, program calculation of a theoretical side boundary value and comparison with the current actual side boundary value. According to the invention, on-site drawing-free and off-line construction is realized, the measurement error rate is greatly reduced, the construction precision is improved, and the construction progress is accelerated. The problems of cost waste and the like caused by blind backfilling, repeated repairing and over-excavation and under-excavation reworking during dam side boundary construction are successfully solved, dam side boundary construction is scientifically and reasonably controlled in real time in the whole process, and the construction precision and attractiveness of a dam body are greatly improved.

Description

technical field [0001] The invention relates to the field of dam construction, in particular to a dam sideline control method based on a GPS-RTK surveying instrument and a programmable calculator. Background technique [0002] During dam construction, controlling the edge accuracy of each elevation of each dam is an important link in dam construction. At present, the control of each elevation edge of the dam still relies on the GPS-RTK surveying instrument to manually collect the data of each elevation edge of the dam to compare with the design value, and then correct the edge to meet the design requirements. GPS-RTK technology is widely used in engineering surveying. Because of its simple operation, little impact on terrain and climate, and quick and independent completion of surveying and design tasks, it greatly improves the efficiency of surveying work. However, manual comparison of design drawings The method is inefficient and time-sensitive. [0003] For this reason,...
