Description

Technical Field

[0001] The utility model relates to the technical field of settlement monitoring equipment, in particular to a railway roadbed layered settlement monitoring device. Background Art

[0002] Railway subgrade is the foundation of track structure. Due to the influence of self-weight, train load and environmental factors, the subgrade soil will produce uneven settlement at different depths. Therefore, monitoring the settlement of railway subgrade is a stability factor to ensure the safety of train operation.

[0003] When monitoring the settlement of railway subgrades, layered monitoring is sometimes used. Layered monitoring can accurately locate the deformation position and degree of each soil layer, such as the compression deformation of the subgrade surface and the consolidation settlement of the deep foundation, to avoid missing internal hidden dangers due to single surface monitoring. The existing layered settlement meter magnetic ring is installed on the outside of the protective tube through a spring iron sheet. Its working principle is based on the coordinated deformation of the magnetic ring and the soil layer. However, after this traditional structure is installed in the borehole, it will fill the remaining space in the borehole. The filling material and the original soil layer are prone to separation, which leads to a small contact area between the spring iron sheet on the outside of the magnetic ring and the original soil layer in the borehole and a short insertion length into the soil layer, thereby weakening the friction between the magnetic ring and the original soil layer. When the soil layer settles or shifts, the magnetic ring cannot effectively move synchronously with the soil layer, resulting in "lag" or "slip", resulting in distorted measurement data and failure to truly reflect soil deformation. It may also cause misjudgment of settlement trends, affecting the safety assessment and maintenance decisions of railway subgrade projects. Utility Model Content

[0004] The purpose of the utility model is to provide a railway roadbed layer settlement monitoring device, which can effectively solve the problems in the background technology.

[0014] As a further preferred solution of the present invention, the lifting cone block is installed in the protective tube through the insertion of a steel wire rope.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the present invention, a sleeve is inserted into the outside of the protective tube, and a mounting ring is installed in the protective tube at the same horizontal position as the magnetic ring through the cooperation of multiple connecting blocks, so that multiple plug-ins can be inserted between the magnetic ring, the mounting ring and the connecting blocks. When the combination of multiple protective tubes is inserted into the borehole, the cooperation of the conical block can be lifted so that one end of the plug-in plate can be inserted into the original soil layer inside the borehole, which can increase the contact area with the soil layer and the anchoring force, so that the magnetic ring can follow the deformation of the soil layer more closely, reduce slip lag, and thus improve data accuracy.

Positioning pieces 14 are fixedly installed on the top and bottom of the connecting block 5. A second through-grooves 15 are provided in the connecting block 5. The connecting block 5 and the positioning piece 14 are inserted and installed in one of the positioning grooves 18, and one side of the connecting block 5 also passes through the slide groove 10 to abut against one side of the plate sleeve 12. The magnetic ring 3 and the positioning piece 14 and The mounting rings 4 are fixedly connected by screws. After the magnetic ring 3 is connected to the mounting ring 4 through multiple connecting blocks 5, installation and movement conditions can be provided for the plug-in plate 6. Rubber pads 17 are fixedly installed on the top and bottom of the plug-in plate 6. One end of the lifting cone block 7 is a triangular piercing portion, and the other end of the plug-in plate 6 is an arc-shaped force-bearing portion. The plug-in plate 6 corresponds to the third through-groove 16, the second through-groove 15 and the first through-groove 13, and the piercing portion of the plug-in plate 6 is placed on the outside of the magnetic ring 3. Multiple plug-ins 6 are inserted and installed in the magnetic ring 3, the mounting ring 4, and the connecting block 5, so as to facilitate the insertion of the lifting cone block 7 into the soil layer, thereby improving the accuracy of the measurement data. The lifting cone block 7 is installed in the protective tube 1 through a wire rope.

[0029] It should be noted that the present invention is a railway roadbed layered settlement monitoring device. Before use, the magnetic ring 3 and the mounting ring 4 need to be installed on the outside of the casing 2 and inside the protective tube 1 respectively. That is, the casing 2 is first inserted and installed on the outside of the protective tube 1, and the positioning groove 18 corresponds to one of the slide grooves 10. Then, one side of the connecting block 5 is extended through the positioning groove 18 and the slide groove 10 to the protective tube 1, and the positioning piece 14 is also placed in the positioning groove 18. Then, the magnetic ring 3 can be inserted and installed on the outside of the casing 2, and the mounting ring 4 is placed in the protective tube 1, and the positional relationship between the outer fixing seat 11 of the mounting ring 4 and the connecting block 5 is reduced. Then, the magnetic ring can be screwed through the magnetic ring 3 and the through hole in the positioning piece 14 and threadedly connected to the screw groove on one side of the fixing seat 11, the installation of the magnetic ring 3, the mounting ring 4 and the connecting block 5 can be completed. Finally, the plug plate 6 is extended from the first through groove 13 in the magnetic ring 3 through the second through groove 15 and the third through groove 16 to the plug plate 6. Then, multiple protective tubes 1 can be threadedly connected to each other through the threaded tube 9, and the threaded tube 9 at one end of one of the protective tubes 1 is installed with the reference ring 8. Then, the lifting cone block 7 is placed in the protective tube 1 away from the reference ring 8, and the wire rope on the lifting cone block 7 is passed through multiple protective tubes 1 and led out from the threaded tube 9 near the reference ring 8. Then, the roadbed can be drilled by the drilling rig. After drilling and cleaning the inside of the borehole, the combined structure of multiple protective tubes 1 and casing 2 can be inserted into the borehole. At this time, the reference ring 8 can be limited upward, and the wire rope on the lifting cone block 7 can be dragged by traction or winding equipment to make the lifting cone block 7 move upward in the multiple protective tubes 1. After the lifting cone block 7 contacts one end of the multiple plug-in plates 6 located on the inner side of the corresponding mounting ring 4, the plug-in plates 6 will be driven to move upward. Then, the plug-in plates 6 drive the casing 2 to move upward on the outside of the protective tube 1 through the magnetic ring 3, the mounting ring 4, and the connecting block 5, and make the top of the connecting block 5 contact the top of the slide groove 10, thereby limiting the magnetic ring 3, the mounting ring 4, and the connecting block 5. Move upward. At this time, the lifting cone block 7 continues to move upward by the hand dragging force inside the lifting cone block 7 and squeezes one end of the three plug plates 6 to one side simultaneously, so that the other end of the plug plate 6 gradually penetrates into the soil layer inside the borehole, completing the final installation of the magnetic ring 3. As the lifting cone block 7 continues to move upward, the remaining plug plates 6 are inserted into the soil layer inside the borehole in the same way as above, and the lifting cone block 7 is pulled out from the uppermost protection tube 1. Then, the assembly of multiple protection tubes 1 is lifted up a certain distance in the borehole through the reference ring 8, and the casing 2 is placed in the middle position outside the protection tube 1, and the reference ring 8 is fixed to the reference structure on the ground. Subsequently, the borehole can be filled.

[0030] During detection, the built-in electromagnetic induction device can be used to lower the protective tube 1 to different depths, and the position of the magnetic ring 3 can be detected to measure the settlement of different soil layers.
