Measurement method for measuring elevation and flatness of concrete surface

Abstract

The invention discloses a measurement method for measuring the elevation and flatness of a concrete surface. The method comprises the following steps: freely setting up a station by using a total station, thereby obtaining a three-dimensional coordinate of the set station; performing real-time tracking measurement on a prism on a measurement frame, and acquiring a three-dimensional coordinate of a central point of the prism on the measurement frame; by utilizing an ultrasonic measurement element mounted on the measurement frame, acquiring the actual three-dimensional coordinates of any position of the concrete surface, wherein the three-dimensional coordinates comprise plane coordinates and elevation of a certain position on a to-be-detected concrete surface; transmitting the data observed by the total station in real time and the data measured by ultrasonic waves to a data computer in real time; and realizing batch computing of the measured design plane coordinates and elevation of the concrete surface. The problems that elevation measurement difficulty is caused and whether the flatness on the concrete top surface meets the standard inspection requirement cannot be detected in the construction process in real time because a leveling rod is inconveniently directly arranged on the concrete surface in the concrete construction process in a leveling method are solved, and the method disclosed by the invention has the characteristics of rapidness, accuracy, intelligence and high efficiency. Moreover, the construction quality is guaranteed, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a method for measuring the elevation and flatness of concrete surfaces, in particular to a method for measuring the elevation and flatness of concrete surfaces in the construction of slab ballastless track base plates. Background technique [0002] At present, in the construction measurement and control of the domestic slab ballastless track base plate, the traditional leveling method is used to control the top surface elevation, and the artificial scraping surface leveling is used to control the top surface flatness. This construction measurement process has the following disadvantages: [0003] 1. Only one single point can be measured at a time, the manual measurement workload is heavy, and it is easy to cause human error; [0004] 2. The amount of on-site calculation data is large, batch calculation cannot be realized, and human calculation errors are prone to occur; [0005] 3. During the concrete construction process, th...
