Embodiment 1

[0025] The present invention will be described in further detail below according to accompanying drawing:

[0026] according to figure 1 , figure 2 , image 3 It can be seen that a portable in-hole instrument positioning embedding device is composed of a positioning rod (1), a positioning plate (2), a positioning buckle (4) and a connecting pin (7) and other components. The connection relationship is: the positioning rod (1) stands in the drill hole (5); the positioning plate (2) is fixed on the positioning buckle (4) according to the position of the specific monitoring instrument mark (3). On the rod (1), the monitor mark (3) is fixed on the positioning plate (2); the positioning buckle (4) is inserted on the positioning plate (2) with a connecting pin (7). The specific operation process is: A. The monitor label (3) is fixed on the positioning plate (2) with a strong glue with good viscosity, and the positioning plate (2) and the positioning buckle (4) are connected with ...

Abstract

The invention discloses a convenient positioning and embedding device for in-hole instrument markings. The positioning rod stands in the borehole, the position of the monitoring instrument mark on the positioning plate is fixed on the positioning rod with a positioning buckle, and the monitoring instrument mark is fixed on the positioning plate. , the positioning buckle is inserted into the positioning plate with the connecting pin, the monitor standard is fixed on the positioning plate with superglue, and the positioning plate and the positioning buckle are connected with the connecting pin. The positioning plate of the monitor target is fixed on the positioning rod, and is fixed layer by layer from bottom to top. Insert the positioning rod of the monitor target into the borehole, insert the grouting pipe into the borehole, and inject grout until the grout fills the buried hole. The device has a simple structure and does not require special and complicated processing techniques; it is easy to operate and does not require cumbersome installation operations; its positioning is accurate, it is not restricted by the harsh external environment, and it does not affect the backfilling construction. 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, in particular to a convenient positioning and embedding device for in-hole instrumentation markers, which is suitable for positioning and installing structural status monitoring instrumentation indicators on completed projects, for accurate, convenient and rapid installation and monitoring The instrument standard 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 borehole and the extremely limited installation space, it is difficult to bury the monitoring instrument. Therefore, it is a problem ...
