High-precision measuring method for concrete pouring surface elevation of cast-in-situ bored pile

Abstract

The invention discloses a high-precision measuring method for the concrete pouring surface elevation of a cast-in-situ bored pile, which includes an ultrasonic probe fixing device, an ultrasonic measurement and analysis device, a measurement means and a data analysis and processing technology. The ultrasonic measurement and analysis device is bound on a concrete guide pipe through the ultrasonic probe fixing device, concrete is poured into the cast-in-situ bored pile through the concrete guide pipe according to a standard construction procedure, the liquid level in a hole rises accordingly, the ultrasonic probe measures different ultrasonic signals along with different media, and when the ultrasonic probe detects the concrete, the ultrasonic signal processing instrument can give out early warning according to the waveform and the amplitude as criteria, and concrete pouring surface elevation detection early warning of the cast-in-place concrete pile in a project is achieved. The cast-in-situ bored pile is layered through an ultrasonic method, the problem that a traditional measuring device is inaccurate and asynchronous in measurement can be solved, the engineering construction efficiency can be improved, the cost can be saved, and the method is suitable for wide application and popularization.

Description

technical field [0001] The invention relates to the technical field of building and civil engineering construction, in particular to a high-precision measuring method for the concrete filling surface elevation of bored piles. Background technique [0002] In recent years, with the continuous improvement of the national economy, there are more and more houses, bridges and large docks. Bored piles have become one of the most commonly used foundation forms in the construction industry due to their advantages such as wide range of applicable foundations, construction noise and economic superiority. Due to the presence of mud and laitance above the concrete pouring surface during the pouring of bored piles, the entire pouring process is invisible, people cannot determine the concrete pouring elevation, and the quality of concrete pouring construction is difficult to guarantee. In order to solve this problem, the current construction site mostly adopts super-filling construction,...
