Embodiment Construction

[0018] Below in conjunction with the examples, the present invention is further described, the following examples are illustrative, not limiting, and the protection scope of the present invention cannot be limited by the following examples.

[0019] A method for detecting the depth of an underground pipeline, the steps are:

[0020] (1) A hydraulic sensor is packaged in the probe 3, the sensing film of the hydraulic sensor is connected to one end of the water pipe 4, and the other end of the water pipe is connected to the hydraulic tank 7 on the ground 2, and there is a height difference between the liquid level of the hydraulic tank and the probe The hydraulic pressure will be generated, the hydraulic pressure is received by the sensor and converted into an electrical signal, and the electrical signal is transmitted to the signal acquisition instrument 8 on the ground through the cable 6, and the signal acquisition instrument converts the hydraulic pressure into an elevation o...

Abstract

The invention relates to a method of for detecting the depth of underground pipelines, which comprises the following steps: (1) connecting a probe with a hydraulic tank as well as a signal acquisition instrument by cables, connecting a rope to the probe; (2) threading a detecting rope in an empty sleeve of a to-be-detected well embedded with pipelines by a threading device; setting a bench mark near an end well on the ground; measuring the elevation of the bench mark by a geometric leveling method; (3) measuring the relative height of the bench mark bya hydraulic sensor and driving the probe to move in the empty sleeve, meanwhile, measuring the heights of the hydraulic sensor in different positions; (4) calculating horizontal shift distance L of a detected point according to the Pythagorean proposition; and (5) summarizing to obtain embedding depths of the pipelines embedded in different distances. The method effectively avoids the interference between to-be-built underground projects and the embedded pipelines, meets building requirement of modernized urban underground projects, and facilitates construction of the urban underground projects.

Description

technical field [0001] The invention belongs to the field of detection, in particular to a method for detecting the depth of underground pipelines. Background technique [0002] With the development of urban construction, many complicated above-ground lines are buried underground by non-excavation methods to provide a beautiful city environment for the public. When adopting non-excavation methods to bury communications, power and other pipelines, the casing method is generally used, and the pipelines are installed in the casing; in order to facilitate future line expansion, more casings need to be pre-buried. At present, due to the rapid urban construction and the intertwined underground pipelines, the buried underground pipelines will inevitably interact with the underground projects to be constructed. Improper operation and construction may damage the buried underground pipelines. Therefore, it is very important to detect the buried underground pipelines. important. [0...
