Fiber-optic endoscope used for half-grouting sleeve and machining method of fiber-optic endoscope and application of fiber-optic endoscope

Abstract

The invention discloses a fiber-optic endoscope used for a half-grouting sleeve and machining method of the fiber-optic endoscope and application of the fiber-optic endoscope, and relates to the technical field of sleeve detecting and monitoring. A grouting cavity is formed in the half-grouting sleeve. The bottom end of a steel bar is fixedly connected with a concrete structure layer. The upper part of the steel bar is fixedly connected into the grouting cavity. An outer pipe is made of transparent materials and fixedly connected with the cutting surface of the steel bar. The top end of the outer pipe is plugged through a stopper. The bottom end of the outer pipe extends from the bottom of the half-grouting sleeve to the exterior of the half-grouting sleeve. The side wall of the outer pipeis provided with a tick-mark line. The fiber-optic endoscope is arranged in the outer pipe and can slide in the outer pipe. The observation end, a probe and optical fiber of the fiber-optic endoscopeare used for being connected with a display screen, obtaining images and transmitting image information correspondingly. The fiber-optic endoscope can intuitively, clearly and quantitatively obtain the grouting fullness of the interior of the half-grouting sleeve, judge accurately the construction quality of the half-grouting sleeve, and deal with unqualified parts in time so as to avoid the influence of the half-grouting sleeve with unqualified construction quality on the overall safety of the housings.

Description

technical field [0001] The invention relates to the technical field of sleeve detection and monitoring, in particular to an endoscope for observing the inside of a half-grouting sleeve and a detection method for detecting the grouting fullness of the half-grouting sleeve. Background technique [0002] In recent years, housing industrialization has developed rapidly in our country, and its safety has attracted much attention. The semi-grouting sleeve is used as the connecting structure of the upper and lower shear walls, and its connection stability directly affects the safety of the residence. The grout fullness is an important index to evaluate the construction quality and stability of the half-grout sleeve, and the importance of its detection accuracy is self-evident. [0003] At present, due to the limitation of the structure of the half-grouting sleeve itself, the construction personnel can only observe the filling of the grout from the grout outlet, and cannot observe ...

AI Technical Summary

Problems solved by technology

[0003] At present, due to the limitation of the structure of the half-grouting sleeve itself, the construction personnel can only observe the filling of the grout from the grout outlet, and cannot observe the fullness of the interior, which directly leads to the inability to be intuitive and clear about the fullness of the grouting of the half-grouting sleeve , Quantitatively observed and tested, which leads to the inability to accurately judge the construction quality of the semi-grouting sleeve and affects the overall safety of the residence
