Technical Field
[0001] This utility model relates to the field of geological engineering technology, specifically a retractable ground settlement stratification marker protection device. Background Technology
[0002] Geological engineering primarily studies geological issues related to various engineering construction projects. Its core tasks are: to investigate, analyze, and evaluate the geological conditions and stability of engineering sites; to prevent and reinforce existing geological hazards (such as landslides, debris flows, and ground subsidence) and adverse geological phenomena; and to provide geological basis and solutions for the planning, design, construction, and safe operation of projects, thus achieving an organic integration of "geology" and "engineering." During ground subsidence monitoring, layered markers are protected to facilitate monitoring.
[0003] During use, the protective device employs multiple interlocking protective sleeves to protect the outer side of the stratified marker, thereby ensuring the long-term accuracy of monitoring data. However, existing protective devices, relying solely on a single protective sleeve, are insufficient to effectively guarantee the long-term protective effect of the device, thus reducing the protective capacity of the stratified marker during use. Therefore, a retractable ground settlement stratified marker protection device is proposed to address the aforementioned problems. Utility Model Content
[0004] The purpose of this utility model is to provide a retractable ground settlement stratification marker protection device to solve the problem mentioned in the background art that the existing protection devices, which rely solely on a single protective sleeve, cannot effectively guarantee the long-term protective effect of the device, thereby reducing the protective performance of the stratification marker during use.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a retractable ground settlement stratification marker protection device, comprising an outer protective sleeve, an inner protective sleeve placed inside the outer protective sleeve, and flanges respectively provided at the lower ends of the outer and inner protective sleeves, the flanges being connected by multiple sets of spiral assemblies, multiple sets of guide plates provided on the inner wall of the inner protective sleeve, and fixing plates respectively provided at the upper and lower ends of the guide plates, with second bolts spirally wound on the fixing plates, and the other end of the second bolts being spirally wound onto the inner protective sleeve; The outer protective sleeve has a groove on the outer wall near the upper end, and a rubber pad is placed in the groove. A protective plate is provided on the outer side of the rubber pad. Multiple sets of storage slots are evenly opened on the protective plate and the rubber pad, and a pad is provided in the storage slot. A first bolt is inserted through the pad, the protective plate on one side, and the rubber pad, and the other end of the first bolt is screwed onto the outer protective sleeve. The protective plate has threads on its outer wall, and a protective cover is spirally attached to the outer side of the protective plate. The horizontal plate of the protective cover is located above the outer protective sleeve and the inner protective sleeve, and a sealing ring is provided on the lower end face of the horizontal plate of the protective cover. The inner protective sleeve has a locking groove on its upper end face, and the sealing ring is locked in the locking groove.
[0006] Preferably, the outer protective sleeve forms a spiral locking structure with the inner protective sleeve through multiple sets of flanges and spiral assemblies, and the guide plate forms a spiral locking structure with the inner protective sleeve through multiple sets of fixing plates and second bolts.
[0007] Preferably, the protective plate and rubber pad are connected to the outer protective sleeve by multiple sets of first bolts to form a spiral locking structure.
[0008] Preferably, the threads on the outer wall of the protective plate are separate thread segments, and the storage groove is opened in a smooth position between the thread segments, and the protective cover and the protective plate form a spiral locking structure.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: The outer protective sleeve of the retractable ground settlement stratification marker protection device forms a spiral locking structure with the inner protective sleeve through multiple sets of flanges and spiral components, and the guide plate forms a spiral locking structure with the inner protective sleeve through multiple sets of fixing plates and second bolts. Thus, the spirally assembled double-layer protective sleeve effectively increases the overall protection and environmental isolation performance. The multiple sets of spirally installed guide plates ensure the verticality of its movement while effectively reducing sliding friction. The protective plate and rubber pad of the device form a spiral locking structure with the outer protective sleeve through multiple sets of first bolts. Thus, the spirally installed protective plate and rubber pad protect the connection of the protective sleeve, thereby preventing soil or external environment from affecting the connection of the protective sleeve. The threads on the outer wall of the protective plate of the device are separate thread segments, and the storage groove is opened in the smooth position between the thread segments. The protective cover and the protective plate form a spiral locking structure. Thus, the spirally installed protective cover can further connect the upper ends of the inner and outer protective sleeves while effectively protecting the gaps of the double-layer protective cover.

[0012] 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.
[0013] Please see Figure 1-4 This utility model provides a technical solution: a retractable ground settlement stratification protection device, including an outer protective sleeve 1, an inner protective sleeve 2 placed inside the outer protective sleeve 1, and flanges respectively provided at the lower ends of the outer protective sleeve 1 and the inner protective sleeve 2. The flanges are connected by multiple sets of spiral assemblies. Multiple sets of guide plates 8 are provided on the inner wall of the inner protective sleeve 1, and fixed plates are respectively provided at the upper and lower ends of the guide plates 8. Second bolts 9 are spirally screwed on the fixed plates, and the other end of the second bolts 9 is spirally screwed onto the inner protective sleeve 2.
[0014] Furthermore, the outer protective sleeve 1 forms a spiral locking structure with the inner protective sleeve 2 through multiple sets of flanges and spiral components, and the guide plate 8 forms a spiral locking structure with the inner protective sleeve 2 through multiple sets of fixing plates and second bolts 9. Thus, the double-layer protective sleeve assembly effectively increases the protection and isolation effect of the device on the layered target, while the multiple sets of guide plates 8 effectively ensure its vertical stability during the lifting process.
[0015] The outer protective sleeve 1 has a groove on the outer wall near the upper end, and a rubber pad 5 is placed in the groove. A protective plate 6 is provided on the outer side of the rubber pad 5. Multiple sets of storage slots are evenly opened on the protective plate 6 and the rubber pad 5, and a pad is provided in the storage slot. A first bolt 7 is inserted through the pad and the protective plate 6 and the rubber pad 5 on one side, and the other end of the first bolt 7 is screwed onto the outer protective sleeve 1.
[0016] Furthermore, the protective plate 6 and the rubber pad 5 form a spiral locking structure with the outer protective sleeve 1 through multiple sets of first bolts 7. This effectively prevents the connection of the protective sleeve from directly contacting the soil through the spirally installed rubber pad 5 and protective plate 6 components, and effectively ensures the protective effect at the connection of the protective sleeve through each component.
[0017] The protective plate 6 has threads on its outer wall, and a protective cover 3 is spirally attached to the outer side of the protective plate 6. The horizontal plate of the protective cover 3 is located above the outer protective sleeve 1 and the inner protective sleeve 2. The lower end face of the horizontal plate of the protective cover 3 is provided with a sealing ring 4. The upper end face of the inner protective sleeve 2 is provided with a locking groove, and the sealing ring 4 is locked in the locking groove. It should be noted that the protective sleeve itself has a heat insulation and vibration isolation layer inside the device, thereby effectively ensuring the protective effect of the protective sleeve assembly on the delamination mark. This utility model is a retractable ground settlement delamination mark protection device. All components are standard parts or components known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
[0018] Furthermore, the threads on the outer wall of the protective plate 6 are separate thread segments, and the storage groove is opened in a smooth position between the thread segments. The protective cover 3 and the protective plate 6 form a spiral locking structure, so that the connection of the double protective sleeve is ensured by the spirally installed protective plate 6, while further protecting the connection of the protective sleeve.
[0019] Working principle: When using the retractable ground settlement stratification marker protection device, holes are first drilled at the installation location of the stratification marker, and the retractable protective sleeve and magnetic ring are installed in the holes. The protective sleeve is connected via an expansion joint to protect the stratification marker. During use, the inner protective sleeve 2 is spirally assembled with the outer protective sleeve 1 via a flange and multiple sets of spiral components. This double-layer protective sleeve effectively increases the device's protective effect on the stratification marker and effectively isolates the stratification marker from the influence of soil temperature and other environmental conditions. During use, multiple sets of guide plates 6 are installed on the inner wall of the inner protective sleeve 2 via the first bolt 7. These guide plates 6 effectively ensure the vertical stability of the components during the lifting and lowering process and effectively reduce sliding friction. Meanwhile, rubber pads 5 and protective plates 6 are spirally installed on the outer wall of the outer protective sleeve 1. This prevents soil from directly contacting the connection of the protective sleeve through multiple sets of protective materials, while effectively ensuring the protective effect at the connection of the protective sleeve through components such as rubber pads 5, thereby increasing the overall service life of the retractable protective sleeve. When using the retractable protective sleeve, protective covers 3 can be spirally installed on the outer protective sleeve 1. This further isolates and protects the outside of the connection of the protective sleeve through protective covers 3, while increasing the connection stability of the upper part of the double-layer protective sleeve. At the same time, protective covers 3 can shield and protect the gaps between the double-layer protective sleeve and the gaps between the inner protective sleeve 2 and the layer markers, thereby ensuring that the device can normally monitor ground settlement data, while ensuring the service life of the layer marker components and the accuracy of the monitoring data. This is the usage process of the retractable ground settlement layer marker protection device.
[0020] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
