Abstract

The invention relates to a device for clearing obstacles in an inclination measuring pipe, consisting of three parts, namely an obstacle taking device (2), a connecting rod (3) and a handle (4), wherein the obstacle taking device (2) comprises a plain steel bar (5), a filter net (6), an iron cylinder (7), a control bolt (8) and a hinge door (9). When the device meets the obstacles in descending, the obstacles lead the hinge door (9) to be opened inward, the obstacles enter the iron cylinder (7), and the filter net (6) plays a role of filtering and leads particles with the particle diameter of larger than 1mm to be unable to pass; and the device is taken out, the control bolt (8) is loosened to lead the hinge door (9) to be opened outward, and the obstacles in the iron cylinder (7) are poured out. The device has simple structure, easy operation, good practical effect, low cost and is applicable to the inclination measuring pipe blocked by the obstacles.

Description

technical field

[0001] The invention relates to a device for clearing obstacles inside small-diameter (<100mm) pipelines. In particular, the invention relates to a device and a method for clearing obstacles in an inclinometer tube used for stability monitoring in deep foundation pits and high slope constructions. Background technique

[0002] In the stability monitoring of deep foundation pits and high slopes, it is often necessary to bury inclinometer pipes. The method of embedding the inclinometer pipe can be roughly divided into two types. 1. Borehole embedding: Use a 108mm drill bit to drill holes, and the hole depth must be greater than the depth of the pre-embedded inclinometer pipe. Then assemble the inclinometer tube and do a good job of sealing to prevent the infiltration of mud in the tube. Place the inclinometer pipe into the borehole while watering. Finally, the gap between the hole wall and the inclinometer tube is filled with cement mortar. 2. Embed tog...
