In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, the embodiment of the utility model discloses buried pipeline monitoring device, including scale cabin 2, sleeve pipe 3, pointer 4, nut 5 and upper and lower U type tile, go up the tile middle part and set up the hole that supplies the pointer to pass through, the nut welds directly over the pipeline, and the pointer lower part is installed on the nut, and lower tile 7 and last tile 6 are detained on buried pipeline 8, and the cover barrel cup joints on last tile, and the scale cabin is aimed at pointer point portion and is fixed on the sleeve, specifically can connect for the screw thread, makes the needle point aim at the zero-bit of scale about the scale cabin, and the pointer point is located the positive intermediate position of level in scale cabin simultaneously. Specifically, the end head of the lower part of the pointer is provided with a thread which is directly screwed into the nut, and the top end of the sleeve is provided with a pipe cap 1.

The scale cabin that adopts in this embodiment specifically is middle square, upper and lower circular shape tubular structure, and the higher authority is connected with the pipe cap screw thread, is connected with the sleeve screw thread below, and the scale of four directions of middle square barrel internal design and upper and lower scale to show the relative displacement of pointer point portion.

The buried pipeline monitoring device is installed near a pipeline connecting piece, and particularly, the position of the device is determined firstly on a pipeline design drawing and is generally placed near an elbow, a tee joint and a flange.

The buried pipeline monitoring devices are arranged at intervals of 100-300 meters, the long-distance pipeline can be properly enlarged at intervals, and in the embodiment, the buried pipeline part is provided with one set of monitoring devices every 200 meters.

The upper tile and the lower tile are not connected with any part and are surrounded by soil.

After the device is installed on a buried pipeline (can be installed when a new pipeline is laid or can be installed on an old pipeline), the device can be periodically detected and a risk assessment report is formed, so that the safety problem during operation is effectively solved.

The utility model discloses specific embodiment as follows:

s1, when a new pipeline is constructed, firstly, the nut is welded right above the pipeline, the lower end of the pointer is provided with corresponding threads, and the pointer can be fixed on the pipeline by directly screwing the nut.

S2, placing the lower tile and the upper tile below and above the pointer to form a detection chamber after pressure test and before backfilling, wherein the upper tile is provided with a hole in the middle for the pointer to pass through, and the hole diameter is consistent with the diameter of the sleeve. The tile is not connected with any part, the tile is placed on the upper tile and is surrounded by soil, and then the cylinder body is placed on the upper tile, penetrates through the pointer and is placed on the upper hole and is surrounded by soil.

And S3, aligning the scale cabin with the pointer tip part and fixing the scale cabin on the sleeve so that the pointer tip is aligned with the zero positions of the upper and lower scales of the scale cabin. Meanwhile, the pointer tip is positioned in the middle of the horizontal position of the scale cabin, and a pipe cap is covered.

All the materials are selected from materials with good corrosion resistance.

When the old pipeline is used, the position is selected at first, the soil layer is dug, and objects are placed in the old pipeline, only when the nut is welded, the thickness is measured, the detailed welding process and the detailed construction scheme are calculated and compiled according to the standard of construction under pressure, and if the nut cannot be welded, the nut can be fixed on the pipeline through the steel band bundling, so that the construction safety is ensured.
