Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0041] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordi...

Abstract

The invention relates to the technical field of testing the gripping force of tunnel engineering soil, in particular to a device and method for testing the gripping force of a tunnel side wall embedded body. For the sensor, one side of the pressure sensor is attached to the end surface of the fixed guide column away from the bottom of the anchor hole; the grip test column is attached to the other side of the pressure sensor; the adhesive layer is coated Surrounded by the pressure sensor and the fixed guide column; wherein, the end surface of the grip force test column and the pressure sensor is also provided with an outlet hole inclined to the axial direction, and the connecting wire passes through the outlet hole. The invention judges the strength of the gripping force on the side wall of the tunnel by pulling the gripping force test column outward; it realizes the qualitative test of the local gripping force from a fixed point inside the tunnel, and the testing location is more flexible, the structure of the device is simple, and the test It is convenient and improves the efficiency of testing.

Description

technical field [0001] The invention relates to the technical field of testing the gripping force of tunnel engineering soil, in particular to a device and method for testing the gripping force of a tunnel side wall embedded body. Background technique [0002] In the construction process of the tunnel, bolt support is an indispensable process in the construction. Through the setting of the bolt, the stability of the side wall of the completed tunnel is improved. However, in actual working conditions, although the anchor rod can achieve the above technical purpose, it is difficult to determine the loose force and stabilizing force of the tunnel side wall material at the position where it is installed, that is, the stabilizing force can not be obtained more objectively when the stabilizing force is improved. evaluate. [0003] In related technologies, the surface subsidence measurement method outside the cave or the surrounding displacement measurement method inside the cave ...
