Description

Technical Field

[0001] This utility model relates to the field of grouting safety monitoring technology, specifically to a grouting foundation uplift monitoring recorder. Background Technology

[0002] During the grouting process, when grout is injected into the stratum, the grout flows in the pores and fissures and generates pressure. If the grouting pressure is too high and exceeds the bearing capacity of the stratum, it may cause the particles or rock blocks in the stratum to move upward, resulting in uplift. By monitoring the uplift of the foundation in real time through a grouting foundation uplift monitoring recorder, construction personnel can understand the impact of grouting pressure on the foundation in a timely manner, and prevent excessive uplift of the foundation due to excessive grouting pressure, which may cause safety accidents such as ground heave and building damage, and ensure the safety of surrounding buildings and infrastructure during the construction process. For example, the fiber optic grouting uplift monitoring device with Chinese patent publication number CN214407356U.

[0003] First, confirm the installation location and mark it. Then, fix the sensor base to the foundation with bolts to ensure the base is stable. Next, install the sensor and adjust it to be level, ensuring it is in close contact with the ground. Then, install the recorder main unit in a place close to the monitoring point and not easily disturbed, fix it with a bracket and connect the power supply. Then, connect the sensor and recorder with a signal cable. After installation, turn on the device to test whether it is working properly, calibrate the sensor to ensure data accuracy, and check whether the data transmission is stable, so as to provide reliable monitoring data for grouting foundation construction.

[0004] Considering that installing the aforementioned monitoring recorder involves multiple steps such as fixing the sensor base, leveling, power connection, and signal cable wiring, the operation is relatively complex. After installation, debugging, calibration, and data transmission checks are also required, which involves many steps and may require multiple people to work together, making it quite troublesome. Summary of the Invention

[0005] The purpose of this utility model is to solve the above-mentioned shortcomings and provide a grouting foundation uplift monitoring recorder;

[0006] To achieve the above objectives, this utility model provides a grouting foundation uplift monitoring recorder, including a cover plate, a detection port on the top of the cover plate, a detection sleeve rod inside the detection port, a detection connecting rod threaded to the upper surface of the detection sleeve rod, a magnetic attraction device fixedly connected to the upper surface of the detection connecting rod, a magnetic attraction groove on the surface of the magnetic attraction device, a magnetic attraction fixing component on the inner wall of the magnetic attraction groove, and a monitoring component on the surface of the magnetic attraction fixing component;

[0007] The magnetic attraction fixing assembly includes a magnetic plate that contacts the inner wall of the magnetic attraction groove, a sliding plate that is slidably connected to the inner wall of the magnetic plate, a fixing groove that is formed in the inner wall of the magnetic attraction groove, and the surface of the sliding plate that contacts the inner wall of the fixing groove.

[0008] As a further improvement to this technical solution, the monitoring component includes a connecting rod fixedly connected to the surface of the magnetic plate, and a lever monitoring gauge is sleeved on the surface of the connecting rod.

[0009] As a further improvement to this technical solution, a limiting plate is fixedly connected to the surface of the sliding plate, and a first limiting groove is formed on the surface of the magnetic suction groove, the first limiting groove being connected to the fixing groove;

[0010] The surface of the limiting plate contacts the inner wall of the first limiting groove.

[0011] As a further improvement to this technical solution, a damper is fixedly connected to the inner cavity of the magnetic suction plate, and the end of the damper away from the magnetic suction plate is fixedly connected to the sliding plate.

[0012] As a further improvement to this technical solution, a second limiting groove is provided on the surface of the magnetic suction plate, and the size of the second limiting groove is the same as the size of the limiting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This grouting foundation uplift monitoring recorder employs a structure including a detection sleeve, a detection connecting rod, and a magnetic fixing component. Compared to the traditional method that requires multiple steps to fix the sensor base and perform horizontal adjustments, this device only requires vertically fixing the detection sleeve to the detection port, followed by threaded connection and magnetic fixing. This significantly simplifies the installation process, reduces the number of steps, and allows a single person to complete most of the operations, lowering labor costs and reducing collaboration difficulties. Furthermore, the magnetic fixing component utilizes the interlocking of the sliding plate and the fixing groove, as well as the magnetic attraction between the magnetic plate and the magnetic groove, to provide double protection for the stable fixing of the monitoring component.

[0026] 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. Example

[0027] Please see Figures 1-7 As shown, this embodiment provides a grouting foundation uplift monitoring recorder, including a cover plate 1, a detection port is provided on the top of the cover plate 1, a detection sleeve rod 11 is provided in the inner cavity of the detection port, a detection connecting rod 12 is threadedly connected to the upper surface of the detection sleeve rod 11, a magnetic suction device 13 is fixedly connected to the upper surface of the detection connecting rod 12, a magnetic suction groove 130 is provided on the surface of the magnetic suction device 13, a magnetic suction fixing component 2 is provided on the inner wall of the magnetic suction groove 130, and a monitoring component 3 is provided on the surface of the magnetic suction fixing component 2;

[0028] The magnetic fixing assembly 2 includes a magnetic plate 21 that contacts the inner wall of the magnetic groove 130, a sliding plate 220 that is slidably connected to the inner wall of the magnetic plate 21, a fixing groove 1301 that is opened in the inner wall of the magnetic groove 130, and the surface of the sliding plate 220 contacts the inner wall of the fixing groove 1301.

[0029] First, insert the detection sleeve 11 into the detection port opened in the cover plate 1 and fix it vertically. Then, fit the detection connecting rod 12 onto the surface of the detection sleeve 11 and rotate the detection connecting rod 12 to make it threadedly connected to the detection sleeve 11. Next, magnetically fix the magnetic plate 21 to the magnetic groove 130 on the magnetic device 13. After fixing, slide the slide plate 220 on the inner wall of the magnetic plate 21 to contact the fixing groove 1301 on the inner wall of the magnetic groove 130. At this time, the magnetic fixing component 2 will fix the monitoring component 3 firmly in the corresponding position by the mutual interlocking of the slide plate 220 and the fixing groove 1301, as well as the magnetic attraction between the magnetic plate 21 and the magnetic groove 130, thereby ensuring that the monitoring component 3 can operate stably in subsequent work.

[0030] The improvement in this embodiment is as follows:

[0031] Considering that installing the aforementioned monitoring recorder involves multiple steps such as fixing the sensor base, leveling, power connection, and signal cable wiring, which is relatively complex, and requires debugging, calibration, and data transmission checks after installation, the process is cumbersome and may require multiple people to work together. Therefore, by adopting structures such as the detection sleeve 11, the detection connecting rod 12, and the magnetic fixing component 2, compared to the traditional complex operation of fixing the sensor base and leveling, the detection sleeve 11 is vertically fixed to the detection port, and then the threaded connection and magnetic fixing are performed in sequence. This greatly simplifies the installation process, reduces the number of installation steps, and allows a single person to complete most of the operations, reducing labor costs and the difficulty of collaboration. Furthermore, the magnetic fixing component 2 utilizes the interlocking of the sliding plate 220 and the fixing groove 1201, as well as the magnetic attraction between the magnetic plate 21 and the magnetic groove 130, to provide double protection for the stable fixing of the monitoring component 3.

[0032] In order for the monitoring component 3 to monitor the lifting of the cover plate 1, it is necessary to further disclose the parts of the monitoring component 3. Therefore, the monitoring component 3 includes a connecting rod 31 fixedly connected to the surface of the magnetic suction plate 21. A lever monitoring gauge 32 is sleeved on the surface of the connecting rod 31. When the cover plate 1 is lifted due to changes in the foundation force or other reasons, the detection sleeve 11, which is closely connected to the cover plate 1, will move synchronously. Since the detection connecting rod 12 and the detection sleeve 11 are securely connected by threads, and the magnetic suction device 13 is fixed to the detection connecting rod 12, the monitoring component 31 is also fixed to the magnetic suction plate 21. On the connecting rod 12, the displacement of the detection sleeve rod 11 will be transmitted to the detection connecting rod 12 and the magnetic suction device 13 in sequence. The connecting rod 31 in the monitoring component 3 is fixedly connected to the surface of the magnetic suction plate 21. When the magnetic suction plate 21 moves, the connecting rod 31 will also move. The lever monitoring gauge 32 is sleeved on the surface of the connecting rod 31. Its internal structure can convert the displacement of the connecting rod 31 into the rotation of the pointer or the change of the number. By reading the value displayed on the lever monitoring gauge 32, the staff can intuitively obtain the lifting displacement of the cover plate 1.

[0033] In order to keep the slide plate 220 stable when it is located on the inner wall of the fixed groove 1301 and to prevent the slide plate 220 from falling off the inner wall of the fixed groove 1301 due to the lifting of the bottom, a limiting plate 2201 is fixedly connected to the surface of the slide plate 220, and a first limiting groove 1302 is provided on the surface of the magnetic suction groove 130, which is connected to the fixed groove 1301.

[0034] The surface of the limiting plate 2201 contacts the inner wall of the first limiting groove 1302. When the slide plate 220 moves to the inner wall of the fixing groove 1301, the limiting plate 2201 connected to it will also move synchronously, so that the surface of the limiting plate 2201 is exactly located on the inner wall of the first limiting groove 1302. Once the slide plate 220 shows a tendency to shake, since the limiting plate 2201 is restricted by the inner wall of the first limiting groove 1302, it can effectively constrain the position of the slide plate 220, thereby preventing the slide plate 220 from leaving the inner wall of the fixing groove 1301.

[0035] To facilitate the separation of the magnetic plate 21 from the magnetic groove 130 during disassembly, the sliding plate 220 needs to be released from its interlocking state with the fixing groove 1301. Therefore, a damper 22 is fixedly connected to the inner cavity of the magnetic plate 21. The end of the damper 22 away from the magnetic plate 21 is fixedly connected to the sliding plate 220. By moving the limiting plate 2201, the sliding plate 220 can slide and move into the inner cavity of the magnetic plate 21. At this time, the damper 22 will retract, cooperating with the sliding plate 220 to slide. The sliding plate 220 will gradually separate from the inner wall of the fixing groove 1301. Then, the magnetic plate 21 can be pulled forcefully to separate it from the magnetic groove 130, and the device can be disassembled at this time, which is relatively convenient.

[0036] Considering that the sliding limit plate 2201 will be blocked by the magnetic suction plate 21 during the sliding process, which will prevent the limit plate 2201 from sliding and thus prevent the slide plate 220 from moving, a second limiting groove 210 is provided on the surface of the magnetic suction plate 21. The size of the second limiting groove 210 is the same as the size of the limit plate 2201.

[0037] When it is necessary to move the limiting plate 2201, it can be slid into the second limiting groove 210. Since the size of the second limiting groove 210 is the same as that of the limiting plate 2201, it can fully accommodate the limiting plate 2201, thereby effectively avoiding the obstruction caused by the magnetic suction plate 21 to the sliding of the limiting plate 2201.

[0038] In practical use, the grouting foundation uplift monitoring recorder of this utility model first drills a detection hole downwards from the upper part of the completed cover plate 1, with the depth of the detection hole reaching into the lower foundation of the cover plate. Then, the detection sleeve 11 is inserted into the detection opening of the cover plate 1 and fixed vertically. Next, the detection connecting rod 12 is sleeved on the surface of the detection sleeve 11, and the detection connecting rod 12 is rotated to make it threadedly connected to the detection sleeve 11. Subsequently, the magnetic suction plate 21 is magnetically fixed to the magnetic suction groove 130 on the magnetic suction device 13, and the sliding limiting plate 2201 is moved to its position. After the magnetic suction groove 130 and the magnetic suction plate 21 are fully aligned, the force on the limiting plate 2201 is released. At this time, the elastic force of the damper 22 itself will push the slide plate 220 to the inner wall of the fixing groove 1301. During this process, the movement of the slide plate 220 will drive the limiting plate 2201 to move to the inner wall of the first limiting groove 1302. After the fixing groove 1301 and the slide plate 220 are interlocked, the magnetic suction fixing component 2 will support the monitoring component 3. The displacement of the detection sleeve rod 11 can be detected by the lever monitoring gauge 32.
