Description

Technical Field

[0001] This utility model relates to the technical field of settlement and displacement monitoring systems, specifically to an anchoring structure for a wire-sleeve type displacement monitoring system. Background Technology

[0002] In the current process of soft soil foundation treatment, settlement monitoring of soft soil layers generally uses a settlement observation system to acquire settlement data. However, the monitoring elements used to acquire data in the settlement observation system need to be installed inside the borehole.

[0003] The monitoring element used in typical settlement monitoring systems is a solid conical anchor head, which is connected to the anchor head by a guy wire. Settlement data is obtained by comparing the length of the anchor head as it moves. However, existing settlement monitoring systems can usually only measure the soft soil layer vertically downwards from the location where they are set up. In areas with large soil settlement and a limited number of boreholes, the area affected by the soft soil layer that can be measured is very limited. Moreover, when adjusting the anchor head by the guy wire and refitting it to the fixed anchor head component, jamming can easily occur, making it difficult to adjust the position of the anchor head. Utility Model Content

[0004] To address the technical deficiencies in the background art, this utility model proposes an anchoring structure for a wire-sleeve displacement monitoring system, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows: An anchoring structure for a wire-sleeve displacement monitoring system includes an isolation plate and an anchor head. The isolation plate has a first connecting portion and a second connecting portion at its two ends, respectively, which are inserted into a soft soil layer. The end of the first connecting portion is recessed to form a mating opening. A pull wire extends through the middle of the isolation plate from the mating opening side. One end of the anchor head has a mating portion for engaging with the mating opening. One end of the pull wire is rotatably connected to the anchor head, allowing it to be pulled by or driven towards the anchor head, thus enabling the mating portion to engage or disengage from the mating opening.

[0005] As a further embodiment of this utility model, the axial cross section of the mating part and the axial cross section of the mating opening are both semi-circular, and the end face of the anchor head on the outer side of the mating part and the end face of the first connecting part on the outer side of the mating opening are both planar.

[0006] As a further embodiment of this utility model, the anchor head has a mating cavity at one end near the mating part, the pull wire passes through the mating cavity, and the end of the part passing through the mating cavity is rotatably connected to the inner wall of the mating part.

[0007] As a further embodiment of the present invention, the second connecting part includes a pull wire sleeve, which is disposed on the outside of the position where the pull wire passes through the isolation plate, and the pull wire passes into the pull wire sleeve and slides inside the pull wire sleeve.

[0008] As a further embodiment of the present invention, the second connecting part includes a connecting block, which is fixedly connected to the outside of the isolation plate where the pull wire passes through, and the pull wire sleeve is fixedly connected to the end of the connecting block away from the isolation plate, and the pull wire passes through the pull wire sleeve and the connecting block in sequence.

[0009] As a further embodiment of this utility model, the radial length of the isolation plate is greater than the radial length of the first connecting part.

[0010] As a further embodiment of this utility model, the axial cross section of the end of the anchor head away from the mating part is tapered.

[0011] The beneficial effects of this utility model are as follows: the isolation plate in the anchoring structure can be fixed in the vertical or horizontal direction of the borehole, so that the anchor head can work at the bottom and side wall of the borehole. After the anchor head enters the soft soil layer outside the borehole, the position of the anchor head can be adjusted by pulling the line. Moreover, the fit between the mating port and the end of the anchor head is higher, which can reduce the situation of the anchor head getting stuck when it fits into the end of the isolation plate. The anchoring structure is simple in composition and is also convenient to install in the borehole. Attached Figure Description

Detailed Implementation

[0016] This utility model discloses an anchoring structure for a wire-sleeve displacement monitoring system, such as Figures 1-3As shown, the anchoring structure includes an isolation plate 1 and an anchor head 2. The isolation plate 1 has a first connecting part 11 and a second connecting part 12 at both ends that are inserted into the soft soil layer. The end of the first connecting part 11 is recessed to form a mating opening 111. A pull wire 3 is connected through the middle of the isolation plate 1 and extends out from the mating opening 111. One end of the anchor head 2 is provided with a mating part 21 for mating with the mating opening 111. One end of the pull wire 3 is rotatably connected to the anchor head 2, so that it is pulled by the anchor head 2 or driven towards the anchor head 2, thereby realizing the mating part 21 mating with or disengaging from the mating opening 111.

[0017] It should be noted that: when using this anchoring structure, firstly, the anchor head 2 is fixed to one end of the isolation plate 1 along the direction of the mating part 21 and the mating opening 111. Then, the anchor head 2 is inserted into the soft soil layer on any side of the borehole. When the isolation plate 1 is parallel to the bottom wall of the borehole, the anchor head 2 pulls the pull line 3 by the natural settlement of the anchor head 2 in the soft soil layer below the borehole and the connection between the pull line 3 and the anchor head 2. By observing the change in the length mark on the surface of the pull line 3 caused by the pull of the anchor head 2 over a certain period of time, the settlement data of the monitoring area over a certain period of time can be obtained. Alternatively, the first connecting part 11 can be inserted into the soft soil layer around the borehole along a direction perpendicular to the borehole axis. After the isolation plate 1 is parallel to the walls around the borehole, the anchor head 2 pulls the pull line 3 by the natural settlement of the anchor head 2 in the soft soil layer below the borehole and the connection between the pull line 3 and the anchor head 2. The tension line 3 is driven to the anchor head 2, causing the mating part 21 of the anchor head 2 to disengage from the mating opening 111, allowing the anchor head 2 to settle naturally in the soft soil layer outside the borehole. By observing the changes in the length mark on the surface of the tension line 3 caused by the anchor head 2 pulling over a certain period of time, the settlement data of the monitoring area over a certain period of time can be obtained. Moreover, by continuously driving the tension line 3 to the anchor head 2, the position of the anchor head 2 in the soft soil layer outside the borehole can be adjusted, changing the initial position of the anchor head 2 before natural settlement. The anchoring structure is simple in composition and is relatively easy to set up in the borehole. The anchor head 2 can be re-fitted along the direction of the mating part 21 and the mating opening 111 to facilitate the re-monitoring of the settlement of the soft soil layer outside the borehole.

[0018] It needs to be further explained that, such as Figures 1-3 As shown, the axial cross-section of the mating part 21 and the axial cross-section of the mating opening 111 are both semi-circular, and the end face of the anchor head 2 on the outside of the mating part 21 and the end face of the first connecting part 11 on the outside of the mating opening 111 are both planar.

[0019] When the anchor head 2 needs to be pulled back and the anchoring structure removed from the borehole, if the end face of the anchor head 2 on the outside of the mating part 21 and the end face of the first connecting part 11 on the outside of the mating opening 111 are not parallel, then when the anchor head 2 is pulled to a position near the mating opening 111, a portion of the semi-circular mating part 21 will first enter the mating opening 111. As the anchor head 2 continues to be pulled, the mating part 21 will rotate at a position outside the mating opening 111. Simultaneously, the end face of the anchor head 2 on the outside of the mating part 21 and the end face of the first connecting part 11 on the outside of the mating opening 111 will gradually become parallel and approach each other. Finally... When the entire mating part 21 is fitted into the mating opening 111, the end face of the anchor head 2 on the outside of the mating part 21 and the end face of the first connecting part 11 on the outside of the mating opening 111 are parallel to each other. Compared with the rectangular mating opening 111 and the mating part 21, the semi-circular mating opening 111 and the mating part 21 make it easier for the anchor head 2 to be positioned at the end of the isolation plate 1, and the mating part 21 will not get stuck at the mating opening 111. The position of the end of the isolation plate 1 of the anchor head 2 does not shift, so it will not affect the removal of the first connecting part 11 and the anchor head 2 from the soft soil layer outside the borehole, thus making it convenient to remove the entire anchoring structure from the borehole.

[0020] It needs to be further explained that, such as Figure 2 and Figure 3 As shown, the anchor head 2 has a mating cavity 22 at one end near the mating part 21. The pull wire 3 passes through the mating cavity 22, and the end of the part that passes through the mating cavity 22 is rotatably connected to the inner wall of the mating part 21.

[0021] Specifically, the position where one end of the pull wire 3 connects to the inner wall of the mating part 21 after being inserted into the mating cavity 22 is the position where the pull wire 3 transmits power to the anchor head 2. Thus, the anchor head 2 can move within the soft soil layer outside the borehole by transmitting power through the pull wire 3, adjusting the initial position of the anchor head 2 before natural settlement. This position can also be the point of force for the anchor head 2 to pull the pull wire 3 during natural settlement, or it can be the connection point for the pull wire 3 and the anchor head 2 when the entire anchoring structure is removed from the borehole, achieving the effect of pulling the pull wire 3 to pull the anchor head 2.

[0022] It needs to be further explained that, such as Figure 1 As shown, the second connecting part 12 includes a pull wire sleeve 121, which is disposed on the outside of the position where the pull wire 3 passes through the isolation plate 1. The pull wire 3 passes into the pull wire sleeve 121 and slides inside the pull wire sleeve 121.

[0023] Because the borehole needs to be backfilled, the location of the isolation plate 1 will be buried. The position where the guy wire 3 passes through the isolation plate 1 away from the anchor head 2 is easily jammed by the filling material, causing the guy wire 3 to be pulled and moved by the anchor head 2. In order to ensure that the guy wire 3 can still be pulled by the anchor head 2 after backfilling, the guy wire sleeve 121 is used to protect the guy wire 3 to prevent the filling material in the borehole from affecting the movement of the guy wire 3 after backfilling.

[0024] Specifically, such as Figure 1 As shown, the second connecting part 12 includes a connecting block 122, which is fixedly connected to the outside of the isolation plate 1 where the pull wire 3 passes through. The pull wire sleeve 121 is fixedly connected to the end of the connecting block 122 away from the isolation plate 1. The pull wire 3 passes through the pull wire sleeve 121 and the connecting block 122 in sequence.

[0025] The connecting block 122 can connect the isolation plate 1 and the guy wire sleeve 121, and can also cover the position where the guy wire 3 in the isolation plate 1 extends away from the anchor head 2, so as to prevent the filling material in the borehole from entering this position of the isolation plate 1 after backfilling and causing the guy wire 3 to get stuck.

[0026] It needs to be further explained that, such as Figure 1 As shown, the radial length of the isolation plate 1 is greater than the radial length of the first connecting part 11.

[0027] The radial length of the isolation plate 1 is greater than that of the first connecting part 11, which makes the contact area between the isolation plate 1 and the soft soil layer larger, and can keep the position of the isolation plate 1 stable in the borehole.

[0028] It needs to be further explained that, such as Figure 1 As shown, the axial cross section of the end of the anchor head 2 away from the mating part is tapered.

[0029] When measuring the settlement of the soft soil layer around the borehole, the tapered part of the axial section of the anchor head 2 makes it easier for the anchor head 2 to move within the soft soil layer, making it easier for the guy wire 3 to be transmitted to the anchor head 2, thus enhancing the ability of the anchor head 2 to move in the direction perpendicular to the borehole axis, and facilitating the initial position adjustment of the anchor head 2 during natural settlement.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
