Pipe diameter measurement method for vertical and horizontal pipes

Abstract

The invention discloses a method for measuring pipe diameters of vertical pipes and horizontal pipes. The measuring device used in the pipe diameter measuring method includes a main rod arranged vertically and whose length can be adjusted, and a movable sleeve is sleeved on the main rod. , the movable sleeve can rotate under the action of external force, and can move up and down on the main rod and position; two telescopic measuring rods are arranged at the side end of the main rod, and the two telescopic measuring rods are a stretching linkage mechanism, and The angle between the two telescopic measuring rods can be adjusted by rotating the movable sleeve or the main rod; by moving the movable sleeve and / or the main rod up and down, the two telescopic measuring rods extend outward respectively; when the lower end of the movable sleeve is offset against the lower rotating rod , the telescopic measuring rod is fully expanded, in a horizontal state, and perpendicular to the main rod. When measuring, the pipe diameter is measured by moving the movable sleeve up and down, or rotating the movable sleeve or the main rod, so that the two telescopic measuring rods are in different states.

Description

technical field [0001] The invention relates to a wall plastering process, in particular to a pipe diameter measuring method for vertical pipes and horizontal pipes. Background technique [0002] At present, the rain and sewage diversion transformation project of the drainage pipe network in old urban areas is carried out across the country. In the process of pipe network investigation, it is necessary to measure the buried depth, pipe diameter and well room size of the drainage pipe. Due to the complex internal environment of the pipeline, there may be toxic gases in the drainage pipeline. When measuring the pipeline network, it is necessary to wear special clothing and masks for measurement, which is troublesome and has low measurement efficiency. In order to improve efficiency, many workers go down the pipeline without wearing protective clothing to measure, and there have been many poisoning accidents of workers going down the well, and there is also a danger of falling ...

Problems solved by technology

[0004] The above-mentioned detection device can only detect the vertical aperture, but cannot measure the inner diameter and outer diameter of the horizontal pipe, and its use is relatively limited.
