Problems solved by technology

[0006] The torsion angle of the current aluminum alloy inclinometer pipe guide groove is relatively small, and it is better than the standard stipulated in the regulations, but the cost of this kind of pipe is high, and it is not suitable for large-scale engineering safety and geological disaster monitoring and detection
The torsion problem of the same type of plastic pipe fittings is very serious, and most of them do not meet the requirements of the regulations, especially PVC plastic pipes.

Embodiment Construction

[0020] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0021] For deformation monitoring of engineering and geological disasters, deep deformation monitoring is one of the most direct and effective means to obtain deformation characteristics and evolution process of rock and soil mass. At present, the most widely used deep deformation monitoring method in China is to use a sliding inclinometer or a fixed inclinometer. This measurement method requires the cooperation of auxiliary inclinometer pipes. However, the inclinometer pipes currently used in China are not strong enough, The drawbacks of unreasonable measurement structure lead to torsion, bending, and poor structural stability of the inclinometer tube during use, which greatly reduces the measurement accuracy of deep displacement.

[0022] Aiming at the deficiencies of the current inclinometer pipe fittings, the inven...

Abstract

The invention relates to a high-strength double-wall inclinometer casing for inclined displacement measurement. The high-strength double-wall inclinometer casing comprises a plurality of measuring pipe fittings, a plurality of pipe fitting connecting pieces and an axial pressure trigger self-opening type anchor hook base. The measuring pipe fittings are connected through the pipe fitting connecting pieces, the axial pressure trigger self-opening type anchor hook base is connected with the measuring pipe fitting which firstly conducts hole sinking, the measuring pipe fittings are provided with inner walls and outer walls, four concrete filling cavities of inner and outer pair arc structures are formed by the inner walls and the outer walls, a plurality of holes are formed in the outer walls, when the inclinometer casing is submerged in the bottom of drilled holes, pressure is exerted in the axial direction, the axial pressure trigger self-opening type anchor hook base is opened and is anchored to the pedestal rock, and when back filling is carried out on concrete, cement paste enters the concrete filling cavities through the holes. The inclinometer casing has the strong capability of resisting tension and pressure, resisting bending and resisting torsion, the compatible deformation capability of the inclinometer casing and the surrounding rock-soil layer is improved, the upward buoyancy of serous fluid on the inclinometer casing is reduced, and a base of the inclinometer casing and the bed rock are in the fixed connection state all the time.

Description

technical field [0001] The invention relates to the field of deformation monitoring of engineering and geological disasters, in particular to the field of deformation monitoring and detection of deep boreholes, and in particular to a high-strength double-wall inclinometer tube for tilt displacement measurement. [0002] Auxiliary measurement pipe fittings for deep deformation monitoring in geotechnical engineering. [0003] Specifically, it is mainly aimed at the technical improvement and technical replacement of the inclinometer tubes used in the current sliding and fixed inclinometers. Background technique [0004] Over the years, inclinometers have been increasingly used in the safety monitoring of slopes, foundations, dams and other projects. Therefore, the quality of the inclinometer tube matched with the inclinometer has attracted more and more attention, because the inclinometer obtains the displacement of the rock and soil mass by measuring the displacement of the i...
