Abstract
The invention relates to an alarm apparatus and the method for preserving the underground wire pipe. The alarm apparatus comprises a box and a strong magnet block inside the box, wherein the alarm apparatuses are embedded on the upper of the wire or the pipe during a distance. It can obtain the location of the wire or the pipe by using the magnetic measuring apparatus to measure the location of the alarm apparatus.
Description
Technical field
The present invention relates to a kind of alarming device and method that prevents that the underground cables pipeline from being destroyed.
Background technology
Be embedded in cable pipelines such as underground cable, optical cable, running water pipe, gas piping and usually damaged the generation that causes various accidents because of construction, excavated earth.In addition, because of cable and pipeline generally all need be embedded in undergroundly for a long time, easily remotely can't seek its position when needing repairing because of burying the time underground.
Summary of the invention
The objective of the invention is to solve the problem that above-mentioned prior art exists, a kind of alarming device and method that prevents that the underground cables pipeline from being destroyed is provided, can warn underground cables pipeline present position, the underground cables pipeline is destroyed when preventing ground construction, and convenient for maintaining.
For achieving the above object, the invention provides a kind of alarming device that prevents that the underground cables pipeline from being destroyed, characteristics are to comprise a box body and place the interior magnetic block of box body, and this alarming device is embedded in cable or pipeline top.
Described magnetic block is the magnetic block that NdFeB material is made.
Described box body is to burn casting, injection molded with pottery, plastics or plastics with mold pressing.
The described alarming device that prevents that the underground cables pipeline from being destroyed also is provided with the aperture that passes for connection cord in box body.
Utilize described alarming device to prevent the method that the underground cables pipeline is destroyed, characteristics are that alarming device is embedded in cable or pipeline top, every a segment distance one alarming device is set on cable or the pipeline, before construction or maintenance, measures the position of alarming device on the ground to know the position of cable or pipeline with magnetic measurement apparatus.
Utilization the invention enables ground construction and the maintenance pipeline before available magnetic measurement apparatus measure the position that this prevents the alarming device that the underground cables pipeline is destroyed on the ground, thereby know the position of underground cables, pipeline, underground cables, pipeline are destroyed and the generation that causes the accident accidentally when avoiding ground construction, and facilitate for cable, pipeline maintenance.
The present invention is further illustrated below in conjunction with accompanying drawing and embodiment.
Description of drawings
Fig. 1 is connected in the structural representation of underground cables or pipeline for the alarming device that prevents that the underground cables pipeline from being destroyed of the present invention.
Embodiment
As shown in Figure 1, the alarming device 1 that prevents that the underground cables pipeline from being destroyed of the present invention comprises a box body 2 and places magnetic block 3 in the box body 2.Wherein box body 2 useful ceramics, plastics or plastics burn casting, injection molded, the magnetic block that magnetic block 3 is made for NdFeB material (also can adopt other strong magnetic material to make certainly) with mold pressing.Can mark brightly painted literal or symbol on the box body 2 of this alarming device 1,, can when being excavated, the caution workmen stop to excavate with the material and the relevant title of an emperor's reign that identifies cable pipeline.Can be provided with aperture 6 on the box body 2 of alarming device 1, so that a connection cord 4 passes to be banded in this alarming device 1 on cable or the pipeline 5 and to bury underground above it.
The present invention utilizes alarming device 1 to prevent the method that the underground cables pipeline is destroyed, utilize plastic ties to be banded in alarming device on cable or the pipeline and bury underground above it, every a segment distance one alarming device is set on cable or the pipeline, before construction and maintenance, measures the alarming device position on the ground to know the position of cable or pipeline with special-purpose magnetic measurement apparatus.Described special-purpose magnetic measurement apparatus can adopt as the military detection instrument of locate (detect) amine or utilize the simple and easy detector of this principle transformation of the way.
Owing to the alarming device material is corrosion-resistant, magnetic is difficult for degenerating, and can warn underground cables pipeline present position in quite long period, and the underground cables pipeline is destroyed when preventing ground construction, and is that cable, pipeline maintenance facilitate.
Claims (5)
