Description

Technical Field

[0001] The present application relates to the technical field of slope monitoring, and in particular to a pre-buried fill roadbed slope safety monitoring device and equipment. Background Art

[0002] The monitoring methods of slopes in related technologies mainly include surface deformation monitoring using instruments such as GNSS (Global Navigation Satellite System Technology), inclination sensors, and static levels. The fill roadbed slope is a slope that is higher than the original ground and is formed by artificial filling during the construction of highway projects. At present, the safety monitoring plan for fill roadbed slopes is mostly deployed after the construction is completed, and the fill roadbed slopes are monitored as ordinary slopes. However, from the analysis of slope mechanism, the occurrence of landslides is caused by shear failure deep in the soil. When the shear failure of the deep soil continues to develop to form a continuous sliding surface, landslides occur.

[0003] It can be seen that the internal displacement of the soil occurs before the surface displacement, that is, monitoring the deep deformation of the soil can perceive the dynamic changes of the slope earlier and can provide accurate warning earlier. However, deep horizontal displacement monitoring is often not selected due to the high cost of monitoring equipment and the difficulty of equipment deployment, and surface deformation monitoring is more often selected. Based on this, the present application proposes a deep soil displacement monitoring product that is easy to construct, accurate in monitoring, and low in cost, so as to meet the needs of deep horizontal displacement monitoring as much as possible.

[0038] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application after combining the specific content of the technical solution.

[0039] Reference Figures 1 to 5 The embedded fill roadbed slope safety monitoring device of the first aspect embodiment of the present application, the fill roadbed slope includes an original slope 500 and a backfill slope 600 formed on the original slope 500, including a conductive line 100, a force-bearing component 200 and a monitoring component 300.

[0040] The conductive line 100 includes a fixed end 110 and a measuring end 120. The fixed end 110 is arranged in the original slope 500. The conductive line 100 extends from the original slope 500 to the backfill slope 600 based on the fixed end 110, so that the measuring end 120 extends out of the backfill slope 600. The force-bearing component 200 is arranged in the backfill slope 600, and the conductive line 100 passes through the force-bearing component 200. The monitoring component 300 is arranged on the backfill slope 600 and connected to the measuring end 120, so that the monitoring component 300 can obtain information from the conductive line 100. It can be understood that the deep sliding of the slope body drives the force-bearing component 200 and the conductive line 100 to make the monitoring component 300 feel the change. The principle is simple, the monitoring method is direct, and the external interference is small. The monitoring of the deep sliding displacement of the slope body is achieved at a relatively low cost. Compared with traditional deep displacement monitoring equipment, the present application pre-buries the conductive line 100 during the construction phase, which does not affect the subsequent filling and compaction construction. After the filling is completed, the monitoring component 300 is connected and fixed to the conductive line 100 on the slope surface. After adjusting the initial parameters, the deployment can be completed without the need for subsequent drilling. It is also easier to repair or replace after a device failure, has lower power consumption, and can reduce maintenance costs to a certain extent.

[0041] In some embodiments, the monitoring points set on the slope are measurement points that can reflect the changing characteristics of the disaster body. In order to ensure the safety of the slope and the surrounding environment, monitoring warning thresholds are set for the monitoring items as control values ​​based on the relationship between the monitored items and the stability of the monitored slope, the working condition of the support structure, the deformation limit of the surrounding environment, etc.

[0042] In some embodiments of the present application, the monitoring component 300 includes a wire sensor 310, which is connected to the measuring end 120 and is used to monitor the displacement information of the conductive wire 100, so that the monitoring component 300 can obtain the information of the comprehensive deformation of the sliding in the deep part of the soil. It can be understood that the comprehensive deformation of the sliding in the deep part of the soil refers to the deformation of the measuring end 120 caused by the sliding body generating a thrust on the conductive wire 100 through the force-bearing component 200 when the fill soil slides along a certain failure surface, and the deformation is caused by the combined action of vertical displacement and horizontal displacement.

[0043] In some embodiments, the monitoring component 300 includes a first inclined pad 311 and a fixed bracket 312, the fixed bracket 312 is arranged on the first inclined pad 311, the first inclined pad 311 is arranged on the backfill slope 600 so that the fixed bracket 312 is arranged horizontally, the first inclined pad 311 is provided with a first hole for the conductive wire 100 to pass horizontally, and the wire sensor 310 is arranged in the fixed bracket 312 and connected to the measuring end 120. It can be understood that the first inclined pad 311 adapts to the slope of the backfill slope 600 to ensure the smooth installation of the wire sensor 310, and the fixed bracket 312 plays a role in protecting the wire sensor 310 to ensure measurement accuracy while reducing maintenance.

[0044] In some embodiments of the present application, the monitoring component 300 includes a tension sensor 320, which is connected to the measuring end 120 and is used to monitor the tension information of the conductive wire 100, so that the monitoring component 300 can obtain the sliding thrust information of the deep soil. It can be understood that the deep soil sliding thrust refers to the tension on the measuring end 120 of the conductive wire 100 when the sliding body generates thrust on the conductive wire 100 through the force plate 210 when the fill soil slides along a certain failure surface.

[0045] In some embodiments, the monitoring component 300 includes a second inclined pad 321, a bearing plate 322 and a connecting member 323. The tension sensor 320 is arranged on the second inclined pad 321 by connecting the connecting member 323 through the bearing plate 322 and the second inclined pad 321. The second inclined pad 321 is arranged on the backfill slope 600 so that the tension sensor 320 is arranged horizontally. The second inclined pad 321 is provided with a second hole for the conductive line 100 to pass horizontally so that the tension sensor 320 is connected to the measuring end 120. It can be understood that the second inclined pad 321 adapts to the slope of the backfill slope 600 to ensure smooth installation of the tension sensor 320. The bearing plate 322 cooperates with the connecting member 323 to set the tension sensor 320 outside the second inclined pad 321. In some embodiments, the connecting member 323 can be an anchor so that the tension sensor 320 is set between the second inclined pad 321 and the bearing plate 322.

[0046] In some embodiments of the present application, the monitoring component 300 includes a monitoring ruler 330 and a reference line component 331. The monitoring ruler 330 is connected to the measuring end 120. The reference line component 331 is arranged in cooperation with the monitoring ruler 330 and is used to determine the reference line, so as to reflect the deformation data of the deep part of the soil body through the movement of the monitoring ruler 330. It can be understood that the cooperation of the steel ruler and the reference line can manually determine the comprehensive deformation of deep sliding.

[0047] In some embodiments, the monitoring ruler 330 and the conductive line 100 are arranged horizontally, and the reference line component 331 includes a vertically arranged reference line, so that it is easy to read the reading on the monitoring ruler 330. In other embodiments, after the monitoring ruler 330 and the conductive line 100, the scale direction of the monitoring ruler 330 can be set correspondingly, and the reference line direction can be adjusted accordingly, so as to achieve multi-dimensional displacement readings to further facilitate monitoring.

[0048] In some embodiments of the present application, the force-bearing component 200 includes a force-bearing plate 210 and a fixing component 220 disposed on the force-bearing plate 210. The fixing component 220 is disposed on the force-bearing plate 210 and forms a third hole. The conductive wire 100 is disposed through the third hole and can move synchronously with the force-bearing plate 210. It can be understood that the force-bearing plate 210 is buried in the backfill soil and can timely sense the changes in the backfill soil. The conductive wire 100 is linked to the force-bearing plate 210 through the fixing component 220, so that the stress situation is timely transmitted to the monitoring component 300 and monitored.

[0049] In some embodiments, the fixing member 220 is a circular ring disposed on the force-bearing plate 210 , and the circular ring can allow the conductive wire 100 to pass through, so that the conductive wire 100 and the force-bearing plate 210 can move synchronously.

[0050] In some embodiments of the present application, the pre-buried fill roadbed slope safety monitoring device also includes an anchor rod 400, which is used to fix the fixed end 110, and the outer periphery of the fixed end 110 is filled with a mortar layer 410. It can be understood that before the slope is backfilled, the fixed end 110 of the stress transmission line 100 is first fixed to the sliding surface of the original slope 500 with the anchor rod 400, and then the transmission line 100 is straightened and the slope backfill construction is carried out, including the mortar filling construction step. During construction, according to the backfill width, a suitable length is selected to ensure that the transmission line 100 has enough length outside the slope surface to install the measuring end 120 connector. After the backfill construction is completed, the appropriate length of the transmission line 100 is adjusted according to the inclined pad and the slope surface position, and the measuring end 120 connector is installed thereon, and the measuring end 120 connector is connected to the corresponding sensor.

[0051] In some embodiments of the present application, the conductive wire 100, the stress-bearing component 200 and the monitoring component 300 are arranged in groups and multiple groups are arranged, and the monitoring components 300 in each group have the same structure or the monitoring components 300 in at least two groups have different structures. It can be understood that when the equipment is backfilling the slope in layers, the conductive wire 100 and the stress-bearing component 200 are buried at different elevations, and the monitoring component 300 is arranged in a matching manner to ensure the accuracy of monitoring.

[0052] In some embodiments, if manual monitoring is adopted, a steel ruler and a reference line may be installed at the measuring end 120, and deformation data may be obtained by manually observing the movement of the steel ruler; if online monitoring is adopted, a tension sensor 320 or a wire sensor 310 may be installed at the measuring end 120 and mounted on a fixed bracket 312; if a measurement method combining online monitoring and manual monitoring is adopted, a steel ruler and a reference line, a tension sensor 320 and a wire sensor 310 may be respectively provided at multiple measuring ends 120. The comprehensive deformation of deep sliding is manually determined by the steel ruler and the reference line; the comprehensive deformation of deep sliding is automatically determined by the wire sensor 310; and the thrust of deep sliding of soil is determined by the tension sensor 320.

[0053] In some embodiments of the present application, during the backfill construction of the embankment slope, a conductive line 100 with a load-bearing plate 210 is pre-buried inside the backfill soil. When the soil slides, a thrust is generated on the load-bearing plate 210, thereby causing tension and deformation of the conductive line 100. The tension and deformation are monitored. Since the monitored values ​​are different from traditional stress and strain (horizontal displacement and vertical displacement), they are called the comprehensive deformation of deep sliding of the soil and the thrust of deep sliding of the soil. The stability of the slope can be predicted by monitoring the above two variables.

[0054] Reference Figures 1 to 5 The monitoring equipment of the second embodiment of the present application includes the pre-buried fill roadbed slope safety monitoring device of the first embodiment of the present application, and also includes a matching device to constitute a complete monitoring system. Based on the pre-buried fill roadbed slope safety monitoring device of the first embodiment of the present application, this monitoring equipment can utilize a unique layout method, with the help of a conductive line 100 and a force plate 210, to monitor the size and rate of deep sliding displacement of the slope through a monitoring ruler 330, a wire sensor 310 and a tension sensor 320, and realize fill roadbed slope landslide monitoring and early warning according to a preset alarm threshold.

[0055] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
