[0002] A layered mark is a punctuation mark buried in soil layers of different depths. In a ground settlement area, the layered marks are buried in soil layers of different depths and directly lead to the ground. After stability protection treatment, by jointly measuring with other layered marks and bedrock marks, the compression and expansion amounts of different soil layers are measured, and thus the deformation amounts of different soil layers are calculated.

[0003] The existing layered marks are placed in a protection cylinder. Since the diameter of the protection cylinder is larger than that of the layered mark, the width of the扶正 device for the sealing mark cannot be adjusted during installation, and the layered mark may be inclined during clamping, resulting in a large deviation in the measurement of the layered mark. Content of the Utility Model

[0008] Further, the slider includes two sliding pieces and a connecting piece between the two sliding pieces. The sliding pieces are slidably connected to the depressions, and the sliding pieces slide between the upper ring and the lower ring.

[0009] Further, the end of the support rod is provided with a fork, and the fork is rotatably connected to the sliding piece through a rotating shaft.

[0010] Furthermore, the pulley assembly includes a roller and a connecting plate. The roller is disposed on the side wall of the connecting plate and fits against the inner wall of the protective cylinder. Both the upper and lower ends of the connecting plate are rotatably connected to the end of the support rod.

[0011] Furthermore, the upper part of the drive rod passes through the upper ring, the bottom of the drive rod is rotatably connected to the top of the lower ring, the middle part of the drive rod is provided with a positive thread section and a negative thread section, and the two connecting pieces slidably connected to a slide rail are respectively screwed to the positive thread section and the negative thread section.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1 As shown, a layered marker straightening device includes a protective cylinder 1 and a layered marker 2, with the layered marker 2 slidably connected to the protective cylinder 1. It also includes: several slide rails 3 fixed to the side wall of the layered marker 2; a ring assembly 4 disposed on the side wall of the slide rails 3, the ring assembly 4 including an upper ring 41 and a lower ring 42; sliders 5 slidably connected to the slide rails 3, with two sliders 5 on each slide rail 3; a support rod 6 rotatably connected to the sliders 5; a pulley assembly 7 rotatably connected to the support rod 6; a drive rod 8 screwed onto the sliders 5, the top of the drive rod 8 passing through the upper ring 41; and an extension assembly 9 connected to the drive rod 8.

[0026] like Figure 2 As shown, there are three slide rails 3 in total, and the included angle between each slide rail 3 is 120 degrees. The inner wall of the slide rail 3 is fixed to the outer wall of the layered marker 2. The slide rails 3 are evenly distributed on the side wall of the layered marker 2 so that they can be quickly adjusted in multiple directions when straightening. The outer wall of the slide rail 3 is provided with several "convex" shaped recesses 31. Adjacent recesses 31 are parallel to each other and the recesses 31 penetrate the outer wall of the slide rail 3. The recesses 31 can make the slider 5 move in a fixed direction, while restricting the slider 5 from leaving the slide rail 3.

[0027] The upper ring 41 is fixed to the upper side wall of the slide rail 3, and there is a distance between the upper ring 41 and the top of the slide rail 3. The lower ring 42 is fixed to the lower side wall of the slide rail 3, and there is a distance between the lower ring 42 and the bottom of the slide rail 3. There is a gap between the upper ring 41 and the lower ring 42, and the slider 5 moves up and down at the gap.

[0028] like Figure 3 As shown, the slider 5 includes two sliding pieces 51 and a connecting piece 52 between the two sliding pieces 51. The thickness of the connecting piece 52 is less than the height of the sliding pieces 51. The sliding pieces 51 are slidably connected to the recesses 31. The multiple recesses 31 make the movement of the sliding pieces 51 more stable. The sliding pieces 51 slide between the upper ring 41 and the lower ring 42. The outer surfaces of the upper ring 41 and the lower ring 42 protrude from the sidewall of the slide rail 3, thereby limiting the movement range of the slider 5.

[0029] The end of the support rod 6 is provided with a fork 61. The fork 61 is rotatably connected to the sliding piece 51 through a rotating shaft. The connecting piece 52 is located in the middle of the fork 61. The two rotating shafts at the fork 61 are convenient to offset the gap at the bottom of the connecting piece 52, so that the rotation is more stable. The rotating shaft is located on the outer surface of the sliding piece 51. The support rods 6 connected by the two sliding pieces 51 are arranged opposite each other.

[0030] The pulley assembly 7 includes a roller 71 and a connecting plate 72. The roller 71 is located on the side wall of the connecting plate 72. The rotation of the roller 71 does not contact the connecting plate 72. The roller 71 is in contact with the inner wall of the protective cylinder. When the height of the layer marker 2 is adjusted, the friction between the roller 71 and the inner wall of the protective cylinder 1 is small, which facilitates the movement of the layer marker 2 inside the protective cylinder. Both the upper and lower ends of the connecting plate 72 are rotatably connected to the ends of the support rod 6. When the two sliding plates 51 approach each other, the support rod 6 pushes the connecting plate 72 outward, causing the roller 71 to squeeze and push the device, thereby changing the tilt angle of the layer marker 2. When the two sliding plates 51 move away from each other, the roller 71 retracts, thereby cooperating with the advancing roller 71 to adjust the tilt angle of the layer marker 2.

[0031] The drive rod 8 is used to drive the two sliders 5 to move simultaneously. The upper part of the drive rod 8 passes through the upper ring 41 and is slidably connected to the upper ring 41. The bottom of the drive rod 8 is rotatably connected to the top of the lower ring 42. The middle part of the drive rod 8 is provided with a positive thread section and a negative thread section. Two connecting pieces 52, which are slidably connected to a slide rail 3, are respectively screwed to the positive thread section and the negative thread section. When the drive rod 8 rotates, the positive thread section and the negative thread section simultaneously drive the two sliders 5 to move synchronously in opposite directions or towards each other, thereby changing the distance between the roller 71 and the inner wall of the protective cylinder 1. The simultaneous movement of the two sliders 5 also ensures that the roller 71 moves horizontally during adjustment, thus keeping the multiple rollers 71 on the same horizontal plane. By adjusting the position of the rollers 71, this device can adapt to protective cylinders 1 of different widths, and can also straighten the layered markers 2 when there is a deviation in the inner diameter of the protective cylinder 1.

[0032] Extension component 9 is used to control the drive lever 8 above the ground, such as... Figure 4 As shown, the extension assembly 9 includes multiple standard rods 91 and a top rod 92. The multiple standard rods 91 can be spliced ​​together to adapt to different depths of the layered markers 2. The top rod 92 is detachably connected to the uppermost standard rod 91 and is used by the personnel lowering the pipe for driving.

[0033] The standard rod 91 has a vertical rod 911 at the top and a limiting horizontal rod 912 fixed to the side wall of the vertical rod 911. The standard rod 91 has a receiving groove 913 at the bottom. The bottom of the receiving groove 913 has a round hole with the same diameter and height as the vertical rod 911. The two sides of the receiving groove 913 are channels through which the limiting horizontal rod 912 can pass. The vertical rod 911 and the limiting horizontal rod 912 can be inserted into the receiving groove 913. When the upper standard rod 91 rotates, it will drive the lower standard rod 91 to rotate together. The top of the drive rod 8 also has a vertical rod 911 and a limiting horizontal rod 912. Thus, the standard rod 91 can be inserted into the drive rod 8 to control the drive rod 8.

[0034] The top rod 92 has a receiving groove 913 at the bottom and a rotating handle 921 and an electric drill interface 922 at the top. After the top rod 92 is inserted into the uppermost standard rod 91, it can be driven by manual rotation or motor drive, thereby causing the standard rod 91 and the drive rod 8 to rotate simultaneously, ultimately achieving the effect of adjusting the position of the roller 71 to straighten the layered marker 2.

[0035] A bubble level 21 can be placed on top of the layer marker 2. After the layer marker 2 is horizontal above the protective cylinder 1, remove the standard rod 91 and the top rod 92 upwards, and then continue to install the layer marker 2.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
