Embodiment 1

[0027] The present invention will be described in further detail below according to accompanying drawing:

[0028] according to figure 1 , figure 2 , image 3 It can be seen that a casing type in-hole instrument positioning embedding device is composed of a main mounting frame (1), a mounting plate (2), a hollow (3), a positioning threaded hole (7), a positioning bolt (8) and a remaining tube Parts such as wall (9) constitute. It is characterized in that: the monitor label (4) is fixed on the mounting plate (2) with super glue; the mounting plate (2) is fixed on the main mounting frame (1) through the positioning threaded hole (7) and the positioning bolt (8); Install the main frame (1) and insert it into the drilled hole (5) until it reaches the end. The specific operation process is: A. Put the mounting plate (2) with the monitoring instrument mark (4) fixed on the position where the positioning threaded hole (7) is drilled in the inner cavity of the main frame (1), and...

Abstract

The invention discloses a casing type in-hole instrument positioning and embedding device. A monitoring instrument is fixed onto a mounting plate through super glue; the mounting plate is fixed onto a mounting main frame through positioning threaded holes and positioning screws; the mounting main frame is inserted into a drill hole; the mounting plate fixedly provided with the monitoring instrument is arranged in the position inside the inner cavity of the mounting main frame wherein the positioning threaded holes are formed, and then the mounting plate is aligned to the threaded holes and fixedly mounted and positioned on the mounting main frame from top to bottom layer by layer; a grouting pipe is inserted inside the drill hole and performs grouting until the drill hole is filled with grout. The casing type in-hole instrument positioning and embedding device is simple in structure, convenient to operate, free from complex mounting operations, accurate in positioning and capable avoiding restriction of external severe environments and influence on backfilling. The casing type in-hole instrument positioning and embedding device is particularly applicable to positioning and mounting monitoring instruments in narrow space and meanwhile is high in mounting effects and simple in operation.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering state monitoring, in particular to a novel casing-type in-hole instrument marking 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 ur...
