Abstract

The invention provides a device and a method for measuring water surface elevation and plane coordinates of a river channel. The device comprises an RTK centering rod; an angle measuring instrument is adjustably connected to the RTK centering rod along the length direction of the RTK centering rod; a folding overhanging bracket is arranged on the angle measuring instrument; a winding drum is rotatably arranged on the folding type overhanging support, and a plumb floating ruler is wound on the winding drum. According to the invention, the RTK centering rod is inserted and fixed, and the GIS technology is adopted to obtain the insertion and fixing point and the coordinate thereof, thereby ensuring accurate positioning; the folding overhanging bracket is driven by the angle measuring instrument to perform height adjustment and rotation, so that a cantilever end plumb bob of the plumb floating ruler reaches a to-be-measured point of the water surface of a river channel, and the GIS technology, a leveling principle and a total station angle measuring principle are combined to measure the water level data; the folding overhanging bracket can be telescopically folded, is easy to carry, and can be used for measuring anytime and anywhere.

Description

technical field [0001] The invention relates to the technical field of river surveying, in particular to a device and method for measuring the elevation and plane coordinates of the water surface of a river. Background technique [0002] In the current industrial and civil construction in our country, water level measurement refers to the determination of the position of the free surface of the water body, and is one of the important measurement items in hydraulic engineering, river engineering, and port engineering experiments. Water level measurement is often related to the elevation of the datum level, which has high requirements for the accuracy and long-term stability of the measuring instrument. In modern hydraulic tests, the measurement of water level uses computers to collect and process the data of water surface measurement in a centralized manner. The data results are susceptible to external interference, the operating equipment is cumbersome, and the construction...
