Embodiment 1

[0022] The present invention will be described in further detail below according to accompanying drawing:

[0023] according to figure 1 It can be seen that a detachable in-hole instrument positioning embedding device is composed of a mounting plate (1), a hard edge strip (2) and other components. The connection relationship is: the mounting plate (1) is fixed on the four hard side bars (2) according to the position of the specific monitoring instrument mark (3), and the monitoring instrument mark (3) is fixed on the mounting plate (1). The fixing methods of the mounting plate (1) and the monitor standard (3) are all pasted with hydrolytic UV glue. The operation process is: A. Prepare four hard edge strips (2), the length of which is determined according to the depth of the drilled hole (4), but 20-30cm beyond the hole; B. Pre-fix the monitoring instrument (3) on the On the mounting plate (1), apply hydrolyzable UV glue around the mounting plate (1), and stick the hard edge ...

Abstract

The invention discloses a fallable type in-hole instrument positioning and embedding device which comprises a mounting plate, hard edges and a monitoring instrument. The device is characterized in that the position of the monitoring instrument fixed on the mounting plate is fixed on the hard edges, the hard edges are adhered to the periphery of the mounting plate through water soluble UV adhesives, the bottoms of the hard edges contacts with the bottom of a hole, the position of the mounting plate is adjusted according to needs, the four hard edges are carried to place the position-adjusted monitoring instrument into a drilled hole, a space for a grouting pipe is reserved, and the drilled hole is filled by grout to complete embedding. The device is simple in structure, convenient to operate, free of complex mounting and operations, accurate in positioning, unlimited by severe external environments, especially suitable for mounting the monitoring instrument in a narrow space, good in mounting effect and simple to operate, difficulty of monitoring instrument embedding on a built project is solved to a great extent, and the monitoring instrument can be mounted fast, efficiently and conveniently.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering state monitoring, in particular to a new detachable in-hole instrument marker positioning and embedding device, which is suitable for positioning and installing structural state monitoring instrument marks on completed projects, and is accurate, convenient and fast It provides a set of effective devices to install the monitoring instrument standard. 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 borehole and the extremely limited installation space, it is difficult to bury the monitoring instrument. Therefore, it is a problem to be solved urgent...
