Abstract

The invention discloses a device for protecting the bottom shape of an inclination testing hole, and the device comprises a hard or semi-hard plastic tube cooperating with the size of the internal diameter of an inclination testing tube. The hard or semi-hard plastic tube is disposed at an outer side of a cylindrical aluminum core, and two side edges of a longitudinal cross section of the cylindrical aluminum core are shaped like a sawtooth. A high-strength screed layer is disposed between the hard or semi-hard plastic tube and the cylindrical aluminum core, and the mortar compressive strength of the high-strength screed layer is not less than 50Mpa. According to the invention, the device can solve a problem that the inclination testing tube is compressed, guarantees that the inner cavity of the inclination testing tube at a cut position is not compressed remarkably, and creates a condition for a purpose that an instrument can go down to get close to a sliding zone as much as possible.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering monitoring, in particular to a device, a manufacturing method and an application for protecting the bottom pass of an inclinometer hole. Background technique [0002] Landslide geological disaster is the most common type of geological disaster, monitoring and early warning is one of the main engineering measures to deal with landslide geological disaster, and the deep displacement of landslide is usually monitored by borehole inclinometer method. The borehole inclinometer method requires drilling to the vicinity of the slip zone and installing an inclinometer tube. The bottom depth of the inclinometer tube should be lower than the slide zone to enter the stable bedrock. When the landslide produces deep slip, the deep displacement can be calculated by measuring the inclination angle of the inclinometer tube section by section. However, if the deep displacement of the landslide is ...
