Meanwhile, stress and strain in the middle of the pipeline can be monitored, so that the running state of the pipeline can be monitored in real time, and the pipeline is guaranteed to be in real-time safety supervision.

As shown in fig. 3 and 4, the indent caps are connected to the tube wall grooves 6 through the fastening portions, each fastening portion includes a cap-fastening groove and a cap-foot hook 8, the cap-fastening groove is a pair of grooves recessed inward from the opposite wall surfaces of the tube wall grooves 6, and the cap-foot hook 8 is a straight panel extending outward from the edge of the end of the slot-attaching plate 7 and toward the cover plate. The indent lid accessible is rolled up lid foot colludes 8 mode of embedding card lid recess and is steadily inlayed the recess of uncapping.

The card lid recess includes first recess 9 and second recess 10, first recess 9 includes first concave surface and first outer joint face, first concave surface is the plane of the inside extension in surface of perpendicular pipe wall groove 6, first outer joint face is the inclined plane that extends to the groove wall of pipe wall groove 6 to the notch direction of keeping away from pipe wall groove 6 from the inward flange of first concave surface, second recess 10 includes second concave surface and second outer joint face, the second concave surface is the inclined plane that extends inwards and is close to the notch direction of pipe wall groove 6 from the surface of pipe wall groove 6, second outer joint face is the inclined plane that extends to the groove wall of pipe wall groove 6 from the inward flange of second concave surface to the notch direction of keeping away from pipe wall groove 6. The card lid recess is divided into two sections, when the lid foot colludes 8 and gets into first recess 9, for the preinstallation stage, lid foot colludes 8 promptly after embedding first recess 9, still can withdraw from first recess 9 through the form of extruding the frid 7 in opposite directions, takes out the indent lid, and after communication optical fiber and the sensor 5 work of preinstallation had no problem, can push lid foot colludes 8 again to second recess 10, is detained by the second concave surface, can no longer return the adjustment, stable combination.

And a depth plate 11 for stabilizing the embedding depth of the pressure groove cover in the pipe wall groove 6 is also included. The depth plate 11 is a plane extending outward from the end edge of the second outer contact surface and close to the notch of the pipe wall groove 6. The depth plate 11 can support the intersection of the cover foot hook 8 and the groove pasting plate 7 after the cover foot hook 8 is inserted into the second groove 10, so that the cover plate is prevented from being extruded to penetrate into the pipe wall groove 6, and the pressure groove cover can be completely stabilized.

And an optical fiber through hole 12 is formed in the groove pressing cover, and the optical fiber through hole 12 is a through hole horizontally penetrating through the surfaces of the groove attaching plates 7 on two sides close to the cover plate. The communication optical fiber can penetrate through the groove pressing cover through the optical fiber penetrating hole 12, so that the sensor 5 can be conveniently connected, and the positioning can be completed by the groove pressing cover.

The pressure tank cover is also provided with a dragging and supporting disk 13, the dragging and supporting disk 13 is a plane plate which is used for connecting the optical fibers at two sides and penetrates through the lower edge of the hole 12, and the middle part of the dragging and supporting disk 13 is provided with a through hole. The drag support disc 13 is used for dragging communication optical fibers, the communication optical fibers are connected with the sensor 5 in the pipe wall groove 6 through the through hole, particularly, due to the arrangement of the drag support disc 13, heat or stress transmitted to the sensor 5 by the outer side layer can be isolated by the drag support disc 13, and the influence of external interference factors on the work and the monitoring of the sensor 5 can be prevented.

And the elastic pressing part is used for abutting against the sensor 5 and clinging to the bottom surface of the pipe wall groove 6. The suppressing part removes pipe 14 including direct fixed pipe and cover pressure, and direct fixed pipe is for keeping away from the hollow cylinder of cylinder that apron one side extended from the center department of dragging supporting disk 13, and the cover pressure removes pipe 14 and is the cylinder section of thick bamboo of ring cover in the direct fixed outside of managing, and the terminal surface that the cover pressure removed pipe 14 passes through the spring and drags supporting disk 13 to link to each other, and the wall thickness that the cover pressure removed pipe 14 thins gradually along keeping away from dragging supporting disk 13 direction. After placing sensor 5 in pipe wall groove 6, when the indent lid inserts in pipe wall groove 6, the lower extreme of casing pressure removal pipe 14 has contradicted on sensor 5, along with deepening of indent lid, the spring is extruded, the conflict of casing pressure removal pipe 14 to sensor 5 is more stable, can assist sensor 5 better hug closely the structural layer surface and accomplish the monitoring with this, secondly, the lower extreme wall thickness of casing pressure removal pipe 14 is thinner, it is less with sensor 5 contact site area, almost no influence to the monitoring of sensor 5, in addition, the telescopic casing pressure removal pipe of elasticity 14 also can be when the pipeline receives the disturbance better protection sensor 5, finally, hollow directly leads to fixed pipe and casing pressure removal pipe 14 can protect the optic fibre of connecting sensor 5 from top through-hole department.
