Description

Technical Field

[0001] The utility model belongs to the technical field of underground pipeline monitoring, and particularly relates to a pipeline settlement monitoring device. Background Art

[0002] For subways built within cities, it is inevitable that there are already normally operating underground pipelines in the surrounding areas during construction. Since the underground pipelines have been built before, especially some old underground pipelines, no settlement monitoring devices were installed on the pipelines when they were buried. However, during subway construction, it is necessary to monitor the settlement of these pipelines and carry out maintenance in a timely manner to avoid affecting the normal lives of surrounding residents.

[0003] Most of the existing devices for monitoring the settlement of old pipelines generally judge the settlement of the pipeline based on the settlement of the ground above the pipeline. However, during pipeline construction, the soil above the pipeline is generally compacted, which makes it easy for underground settlement to occur but not show it on the surface. If construction is still carried out at this time, there will be serious safety hazards. At the same time, when this happens, the underground pipeline may have sunk, but because the ground above the pipeline has not collapsed and settled together, the general monitoring device cannot monitor the information of pipeline settlement in time, and thus cannot take pipeline maintenance measures in time, which can easily lead to serious construction consequences.

[0004] Therefore, it is necessary to provide an improved technical solution to the above-mentioned deficiencies in the prior art. Utility Model Content

[0005] The purpose of the utility model is to provide a pipeline settlement monitoring device to solve the technical problem that the existing pipeline monitoring device cannot monitor the pipeline settlement in time.

[0006] In order to achieve the above objectives, the pipeline settlement monitoring device of the present utility model provides the following technical solutions:

[0007] A pipeline settlement monitoring device, characterized by comprising:

[0008] A monitoring rod, wherein the monitoring rod has a monitoring section and a settlement display section, the monitoring section is located in the soil above the pipeline, the bottom end of the monitoring section is fixedly connected to the pipeline, and the top end extends vertically upward, the settlement display section has a scale, and the settlement display area is located above the ground, and the bottom end of the settlement display area is fixedly connected to the top end of the monitoring section;

[0009] A connecting block is provided at the bottom of the monitoring section, and the bottom of the monitoring section is fixedly connected to the top of the pipeline through the connecting block;

[0010] The protective tube is sleeved on the outside of the monitoring rod, with the bottom end abutting the outer wall of the pipeline and the top end extending out of the soil. The protective tube and the monitoring rod are slidably matched to reduce the friction between the monitoring rod and the soil.

[0011] As a further optimized technical solution, the side of the connecting block facing the pipeline has a curved surface adapted to the pipeline so as to fully fit the outer wall of the pipeline.

[0012] As a further optimized technical solution, the bottom of the connecting block has an adhesive layer, and the connecting block is bonded and fixed to the pipeline through the adhesive layer.

[0013] As a further optimized technical solution, a sliding structure is provided on the protection tube and / or the monitoring rod to reduce the friction between the protection tube and the monitoring rod.

[0014] As a further optimized technical solution, the sliding structure is arranged on the inner wall of the protection tube.

[0015] As a further optimized technical solution, the sliding structure includes a plurality of sliding wheels, and the sliding wheels are hinged to the inner wall of the protective tube.

[0016] As a further optimized technical solution, the top of the protective tube is provided with a protective plate, the protective plate is provided with a limiting perforation, and the monitoring rod extends out of the ground through the limiting perforation.

[0017] As a further optimized technical solution, a transparent protective cover is fixedly connected to the top of the protective plate, and the portion of the monitoring rod extending out of the soil is located inside the protective cover.

[0018] As a further optimized technical solution, the pipeline settlement monitoring device also includes an alarm component, which is connected to an external alarm system. The alarm component is arranged on one side of the monitoring rod, and a trigger structure is fixedly connected to the set height position on the corresponding monitoring rod. When the monitoring rod drops to the set height position, the trigger structure triggers the alarm component.

[0019] As a further optimized technical solution, the alarm component has an alarm button on the top, and the trigger structure is a horizontal bar set above the alarm button. When the monitoring rod drops to the set height position, the horizontal bar presses the alarm button to trigger the alarm system on the outside.

[0020] Beneficial effect: By fixing and burying the protective pipe and the monitoring rod above the pipeline, the monitoring rod is fixedly connected to the pipeline through the connecting block. In this way, when the underground pipeline sinks again, the pipeline pulls the monitoring rod to slide below the ground. At this time, even if the surface does not show settlement, the settlement of the pipeline can be seen from the sinking of the monitoring rod, so that the settlement of the pipeline can be monitored in time, thereby ensuring construction safety.

DETAILED DESCRIPTION

[0025] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention. The terms "connected" and "connected" used in the present invention should be understood in a broad sense. For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0028] The utility model provides a pipeline settlement monitoring device. A monitoring rod is provided, the bottom end of the monitoring rod is fixedly connected to the pipeline and partially extends out of the soil above the pipeline. Once the pipeline settles, the monitoring rod will be pulled to slide downward. By observing the change in the height of the part of the monitoring rod extending out of the soil, the pipeline settlement situation can be obtained, thereby facilitating timely maintenance of the pipeline.

[0029] Specifically, if Figure 1 、 Figure 2 As shown, the pipeline settlement monitoring device includes a monitoring rod 100 , a connecting block 130 and a protective pipe 140 .

[0030] The monitoring pole 100 comprises a monitoring section 110 and a settlement display section 120. During installation, the monitoring section 110 is located within the soil 200 above the pipeline 300. The bottom of the monitoring section 110 is fixedly connected to the pipeline 300, while the top extends vertically upward. The settlement display section 120 is marked with a scale for convenient reading of settlement data on the pipeline 300. During installation, the settlement display area needs to be exposed above the ground, with the bottom of the settlement display section 120 fixedly connected to the top of the monitoring section 110.

[0031] The connection block 130 is fixedly connected to the bottom end of the monitoring section 110 , and the monitoring section 110 is fixedly connected to the top of the pipeline 300 through the connection block 130 .

[0032] Furthermore, to ensure that the connecting block 130 fully conforms to the outer wall of the pipe 300 and ensures connection strength, the side of the connecting block 130 facing the pipe 300 has a curved surface that matches the pipe 300. In this embodiment, the bottom of the connecting block 130 has an adhesive layer 131, and the connecting block 130 is bonded and fixed to the pipe 300 via the adhesive layer 131. In other embodiments, especially for metal pipes 300, the connecting block 130 can be a strong magnet that is directly attracted to the pipe 300.

[0033] Since the monitoring rod 100 is buried in the soil 200, when the monitoring rod 100 slides along the soil 200, there will be friction with the soil 200. At this time, if the bottom end of the monitoring rod 100 is not connected very firmly, the friction will affect the downward movement of the monitoring rod 100. In order to reduce the friction between the monitoring rod 100 and the soil 200, the protective tube 140 is sleeved on the outside of the monitoring rod 100. During the initial installation, the bottom end of the protective tube 140 abuts the outer wall of the pipeline 300, and the top end extends out of the soil 200. The protective tube 140 and the monitoring rod 100 slide in cooperation. In this way, the protective tube 140 can prevent the soil 200 surrounding the monitoring rod 100 from squeezing the monitoring rod 100, thereby improving the sensitivity of the monitoring results of the monitoring rod 100.

[0034] In order to further ensure that the monitoring rod 100 slides smoothly in the protection tube 140 , a sliding structure is provided on the protection tube 140 and / or the monitoring rod 100 to reduce the friction between the protection tube 140 and the monitoring rod 100 .

[0035] In this embodiment, the sliding structure is provided on the inner wall of the protection tube 140. In other embodiments, the sliding structure may also be provided on the monitoring section 110 of the monitoring rod 100, or the sliding structure may be provided on both the inner walls of the monitoring rod 100 and the protection tube 140.

[0036] In this embodiment, the sliding structure includes a plurality of sliding wheels 141 , and the sliding wheels 141 are hinged to the inner wall of the protection tube 140 .

[0037] Furthermore, in order to prevent the monitoring rod 100 from tilting during the monitoring process and being unable to slide down vertically, thereby affecting the accuracy of the settlement data, a protective plate 150 is provided on the top of the protective tube 140, and a limiting perforation 151 is provided on the protective plate 150, and the monitoring rod 100 extends out of the ground through the limiting perforation 151.

[0038] Furthermore, a transparent protective cover 160 is fixedly connected to the top of the protective plate 150, and the portion of the monitoring rod 100 extending out of the soil 200 is in the protective cover 160. Through the transparent protective cover 160, the settlement of the monitoring rod 100 can be easily observed, and the monitoring device can be kept in a stable working state.

[0039] In addition, during the construction process, settlement does not occur in a gradual and slow process, and is therefore unpredictable. In order to avoid settlement not being discovered in time and affecting construction safety, the pipeline settlement monitoring device also includes an alarm component 170. The alarm component 170 is electrically connected to an external alarm system (not shown in the figure). The alarm component 170 is arranged on one side of the monitoring pole 100, and a trigger structure 180 is fixedly connected to the set height position on the corresponding monitoring pole 100. When the monitoring pole 100 drops to the set height position, the trigger structure 180 triggers the alarm component 170.

[0040] In this embodiment, the alarm component 170 has an alarm button 171 on the top, and the trigger structure 180 is a horizontal bar set above the alarm button 171. When the monitoring pole 100 drops to a set height position, the horizontal bar presses the alarm button 171 to trigger the alarm system on the outside.

[0041] In this way, when sudden settlement occurs, even if no operator discovers it in time, when the settlement exceeds the safety value, the crossbar on the monitoring pole 100 presses the alarm button 171 to trigger the alarm system, which will still attract the attention of the construction workers.

[0042] It will be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
