Mechanical device for mounting inclinometer pipe and mounting method thereof

Technical Field

The invention relates to the technical field of deep displacement monitoring of side slope geological disasters, in particular to a mechanical device for installing an inclinometer and an installation method thereof.

Background

The mountain areas in China are wide in area distribution, and landslide geological disasters often occur under the conditions of natural geological action, rainfall, human factors and the like. According to related data, China is one of the most serious countries in the world with landslide geological disasters, and the economic loss caused by landslide geological disasters reaches billions of yuan every year. In the aspect of landslide geological disaster monitoring, deep displacement monitoring is widely applied to landslide geological disaster prediction and early warning as an indispensable technical means, particularly for soil slopes. At present, deep displacement monitoring is mainly carried out by manually drilling a hole on a slope body, then installing an inclinometer in the drilled hole, and finally placing an inclinometer in the inclinometer to measure the offset distance of the inclinometer so as to monitor the displacement change of the slope body. However, to the monitoring of the inside deep displacement of side slope, the degree of depth of deviational survey hole can reach tens meters or even hundreds of meters, in actual installation, mainly rely on the manpower installation, put the deviational survey pipe in-process under, installer mainly puts slowly through grasping the deviational survey pipe firmly with the hand, but along with the increase of putting the degree of depth, the dead weight of deviational survey pipe is bigger and bigger, operating personnel not only will splice the deviational survey pipe, guarantee the stability of deviational survey pipe, and still prevent the deviational survey pipe tenesmus, need the installation of many operating personnel to accomplish jointly, this has greatly increased operating personnel's the installation degree of difficulty, installation quality and installation effectiveness, and in the installation, the deviational survey pipe easily falls into the drilling, lead to the scheduling problem of waste hole.

Disclosure of Invention

The invention aims to overcome the defects and shortcomings in the existing installation technology and provides a mechanical device for installing an inclinometer pipe and an installation method thereof.

secondly, stopping the downward placement at a position, which is about 30cm away from the center of the circular hole of the base 9, of the caliper 7, wrapping the pipe wall of the inclinometer pipe 10 tightly by the extrusion sleeve 8, placing the pipe wall into the center of the circular hole of the base 9, loosening the caliper 7 after the inclinometer pipe 10 is clamped by the extrusion sleeve 8, and continuing the downward placement for the next time.

Finally, as the inclinometer pipe 10 is continuously lowered, the weight of the inclinometer pipe 10 is larger and larger, the extrusion force between the extrusion casing 8 and the base 9 is larger, and after the upper and lower sections of inclinometer pipe 10 are butted, the inclinometer pipe 10 needs to be lifted upwards by about 20cm through the winch 1, so that the extrusion force between the extrusion casing 8 and the base 9 is reduced, the extrusion sleeve 8 is conveniently taken out, and the inclinometer pipe 10 is continuously lowered.

The beneficial effects of the invention are as follows: the support is fixed by a fastening device, and the axis position of the support is aligned to the central position of the inclinometer orifice, so that the support is ensured to be consistent with the axial direction of the drill hole when the inclinometer pipe is installed.

The hoist engine, wire rope and pulley provide power take off through with calliper, have greatly reduced the degree of difficulty that field operation personnel installed the deviational survey pipe, especially to side slope deep displacement monitoring, the big condition of deviational survey pipe dead weight.

The inside rubber that sets up of calliper, its movable clamp handle are equipped with fastening bolt, thereby press from both sides the fixed deviational survey pipe of movable clamp handle through fastening bolt clamp in the installation to put the in-process down and provide great pulling force.

The cross section of the inner surface of the extrusion sleeve is of a circular structure and is provided with rubber, the outer surface of the extrusion sleeve is a narrow-down wide-up free-form surface, the extrusion force of the extrusion sleeve and the base is increased along with the descending process of the inclinometer pipe, and further the friction force applied to the inclinometer pipe is increased, so that the inclinometer pipe is prevented from slipping and falling.
