Problems solved by technology

However, due to the small diameter of the drilling hole and the extremely limited installation space, and if the instrument mark is directly buried, it cannot be accurately positioned and its position cannot be fixed. These limitations have brought great difficulties to the embedding of the monitor mark

Abstract

The invention discloses a wire rope type in-hole instrument standard positioning embedding device, which is composed of a mounting plate, a flexible suspension line, a threading hole, a positioning screw hole, a positioning bolt, and a counterweight, and is characterized in that: the monitoring instrument standard uses super glue Fix it on the installation board, pass the flexible suspension wire through the threading hole on the installation board, and fix the installation board on the flexible suspension wire with positioning bolts. Hang on the bottom of the flexible suspension wire, insert the grouting pipe into the borehole, and grout until the grout fills the borehole. The device has the advantages of simple structure, convenient operation, no complicated installation and operation, accurate positioning, and is not restricted by the harsh external environment. The device is especially suitable for positioning and installing monitoring instruments in a narrow space, and has good installation effect and easy operation.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering status monitoring, and more specifically relates to a wire-type in-hole instrument marker positioning and embedding device, which is suitable for positioning and installing structural status monitoring instrument markers on completed projects, and provides accurate, convenient and rapid The installation of monitoring instruments provides a set of effective devices. Background technique [0002] In order to ensure the safety and reliability of geotechnical engineering, real-time monitoring of its structural status is a necessary means. For the completed project, its structure cannot be damaged in a large area, so the method of burying the monitoring instrument can only adopt the method of small drilling. However, due to the small diameter of the drilling hole and the extremely limited installation space, and if the instrument mark is directly buried, it cannot be accurately positi...
