Description

Technical Field

[0001] This utility model relates to the field of underground pipeline settlement monitoring technology, specifically a settlement monitoring device for underground pipeline projects using pipe jacking construction. Background Technology

[0002] During pipe jacking construction, settlement monitoring is a key link to ensure project safety and the stability of surrounding buildings and underground pipelines. The settlement monitoring devices used are mainly used to monitor the settlement and deformation of pipelines and surrounding soil in real time or periodically to ensure project safety and prevent accidents such as pipeline rupture and leakage caused by uneven settlement.

[0003] However, to prevent the scale lines on the surface of the settlement monitoring device from being worn during use, a patent document with publication number CN217276146U describes a structure with a chute, a sliding member, and a cover plate. This structure allows the two sets of cover plates to completely cover the scale during use, isolating it from the external environment and preventing corrosion and damage. This ensures the integrity of the scale readings and improves monitoring accuracy.

[0004] Theoretically, the implementation of the aforementioned technical structure is beneficial for protecting the scale lines on the settlement monitoring device. However, according to the description in the aforementioned technical content, using a spring pin to connect the conduit and the settlement monitoring device results in the spring pin being exposed due to its spring-loaded rebound. At this time, the exposed spring pin is very likely to come into contact with stones at the construction site. Under the impact force of the stones, the spring pin is very likely to deform or even be damaged. The damaged spring pin will cause the conduit to separate from the settlement monitoring device, affecting the normal use of the spring pin, reducing the tightness of the connection between the settlement monitoring device and the conduit, and thus reducing the accuracy of underground pipeline settlement monitoring.

[0022] Please see Figure 1 and Figure 3 A settlement monitoring device for underground pipeline engineering using pipe jacking construction includes a pipe body 1. A locking block 2 is fixedly installed on the upper end face of the pipe body 1. A fixing block 3 is movably sleeved on the inner wall of the locking block 2. Connecting components 4 for connecting the locking block 2 are respectively provided on the front and back of the fixing block 3. The connecting components 4 connect the locking block 2 and the fixing block 3. Protective covers 6 located outside the connecting components 4 are threadedly connected to the front and back of the locking block 2. The protective covers 6 are installed on the outside of the connecting components 4 to prevent the connecting components 4 from being exposed and damaged by stones. The right side of the protective cover 6 is movably connected to... There is an elastic rope 7, and the end of the elastic rope 7 away from the protective cover 6 is fixedly connected to the locking block 2. The elastic rope 7 is set to connect the protective cover 6 and the locking block 2 to prevent the protective cover 6 from being lost during disassembly or installation. The upper end of the fixing block 3 is fixedly installed with a movable rod 8 located above the locking block 2. The front of the upper end of the movable rod 8 is provided with a pointer 9. The movement of the pointer 9 on the scale line 11 makes it easy for the staff to observe the settlement height of the underground pipeline. The outer wall of the movable rod 8 is movably sleeved with a vertical rod 10. The front of the vertical rod 10 has scale lines 11 evenly distributed from top to bottom behind the pointer 9.

[0023] The left and right sides of the inner wall of the locking block 2 are respectively fixedly installed with grooves 12 located outside the fixing block 3. The front and back of the locking block 2 are respectively provided with threaded grooves 14 located inside the protective cover 6. The front and back of the locking block 2 are respectively provided with through holes 13 located inside the threaded grooves 14. The inside of the through hole 13 is movably sleeved with the outer wall of the connecting component 4. The opening of the through hole 13 provides a channel for the connecting component 4 to pop out from the inside of the locking block 2.

[0024] Please see Figure 2 and Figure 4 The front and back of the fixing block 3 are respectively provided with mounting grooves 16 for installing the connecting component 4. The mounting grooves 16 provide space for the installation of the connecting component 4. The inner wall of the mounting grooves 16 is evenly provided with sliding grooves 17.

By changing the connection method between the connecting block 402 and the through hole 13, the connection or separation of the locking block 2 and the fixing block 3 can be realized.

[0026] Please see Figure 5 and Figure 2The outer wall of the protective cover 6 is evenly distributed with anti-slip textures 18. The anti-slip textures 18 increase the friction between the worker's hand and the contact surface of the protective cover 6. A baffle 19 located outside the locking block 2 is fixedly installed on the inner side of the protective cover 6. A threaded plate 20 is fixedly installed on the side of the baffle 19 away from the anti-slip textures 18. The outer wall of the threaded plate 20 is threadedly connected to the inner wall of the threaded groove 14. The threaded connection allows the threaded plate 20 to be rotatably installed inside the threaded groove 14 and also to be disassembled from inside the threaded groove 14. A round rod 22 is rotatably connected to the inner wall of the outer side of the protective cover 6. The rotation of the round rod 22 on the protective cover 6 allows the protective cover 6 to be installed without being restricted by the elastic rope 7 during installation or disassembly. An inner side plate 23 located inside the protective cover 6 is fixedly installed at the inner end of the round rod 22. An outer side plate 21 located outside the protective cover 6 is fixedly installed at the outer end of the round rod 22. The outer side of the outer side plate 21 is fixedly connected to the elastic rope 7.

[0027] The front of the upright pole 10 is bolted to a protective shell 29 located outside the scale line 11. A top plate 24 is fixedly installed at the upper end of the upright pole 10. Sleeve rods 25 are fixedly connected to the left and right sides of the lower end of the top plate 24. A second spring 26 is fixedly installed on the top surface of the inner wall of the sleeve rod 25. The second spring 26 is used to connect the telescopic rod 27 and the sleeve rod 25. The lower end of the second spring 26 is fixedly connected to the telescopic rod 27. An extension plate 28 located below the sleeve rod 25 is fixedly installed at the lower end of the telescopic rod 27, and the inner end of the extension plate 28 is fixedly connected to the outer side of the rectangular plate 15.

[0028] Working principle: In use, firstly, the pipe body 1 is placed over the outside of the underground pipeline. Then, the fixing block 3 is inserted into the inside of the locking block 2. The connecting block 402 is pressed and moved into the mounting groove 16. At this time, the connecting block 402 is in a compressed state, and the slider 403 slides inside the sliding groove 17 until the connecting component 4 is completely retracted into the mounting groove 16. As the fixing block 3 continues to move into the locking block 2, the rebound of the connecting block 402 pops the connecting block 402 out of the mounting groove 16 and out of the through hole 13, thus connecting the connecting component 4 to the locking block 2 and the fixing block 3. Then, due to the threaded connection between the threaded plate 20 and the threaded groove 14, the threaded plate 20 is installed in a rotating manner. Inside the threaded groove 14, the protective cover 6 can be fixed to the locking block 2, and the rotation of the round rod 22 on the protective cover 6 ensures that the protective cover 6 is not restricted by the elastic rope 7 during installation, avoiding interference from the elastic rope 7 winding on the protective cover 6. Finally, the upright 10 is installed in the designated area. When the underground pipeline settles, due to the connection of the connecting component 4, the telescopic rod 27 moves vertically downward and stretches the second spring 26. At this time, the movement of the movable rod 8 inside the upright 10 allows the observation of the settlement depth by sliding the pointer 9 on the scale line 11. The protective shell 29 is installed on the outside of the upright 10 to protect the scale line 11 and prevent wear on the scale line 11.
