Problems solved by technology

Drilling and coring is the most direct and widely used detection method. It belongs to the posterior method. The problem is that even if the pile diameter is found to be too small, it is difficult to take remedial measures; if the pile diameter is found to be too large, it is impossible to compensate for the material waste of

Abstract

The invention discloses a construction method for dynamically monitoring the construction effect of a high-pressure jet grouting pile, and belongs to the technical field of jet grouting pile construction. Based on a jet grouting drilling machine formed by combining a jet grouting drill bit equipped with a short-wave infrared spectrometer, jet grouting construction operation is carried out through the following steps to achieve dynamic monitoring of the jet grouting effect. The construction method for dynamically adjusting the jet grouting parameters comprises the steps that a jet grouting construction site is prepared, and the jet grouting drilling machine is transformed; a dynamic monitoring scheme of the jet grouting construction process is determined; a jet grouting dynamic construction scheme is determined; jet grouting construction operation is carried out; and the jet grouting construction operation is completed. Spectral parameters of slurry doped with mineral rock powder are collected by adopting the short-wave infrared spectrometer, and specific spectral parameters are extracted for analysis; and the jet grouting effect of the jet grouting pile is calculated according to the distribution of mineral rock powder in returned slurry and the proportion of the surface area monitored by the short-wave infrared spectrum, and then the construction parameters are changed to meet design requirements.

Description

technical field [0001] The invention relates to the technical field of rotary grouting pile construction, in particular to a construction method for dynamically monitoring the construction effect of high-pressure rotary grouting piles. Background technique [0002] With the continuous development and progress of science and technology, infrared spectrometer has a high detection level. Infrared spectrometer is an instrument that uses the absorption characteristics of substances to infrared radiation of different wavelengths to analyze molecular structure and chemical composition. Infrared spectrometers are usually composed of light sources, monochromators, detectors and computer processing information systems. Infrared spectrometers can not only identify compounds but also accurately determine the content of compounds, and can perform qualitative and quantitative analysis of samples.
