Description

Technical Field

[0001] This invention relates to the field of slope protection structure technology, and more specifically, to a trench slope protection structure. Background Technology

[0002] In building foundation construction, it is often necessary to excavate trenches and foundation pits on the ground. During the excavation process, the sides of the trench may collapse or landslide. Therefore, slope protection is usually set on both sides of the trench to protect the soil slopes on both sides during the trench excavation process, so as to prevent the soil on both sides of the trench from collapsing or landslide and to ensure the safety of construction.

[0003] However, during the trench excavation process, as the soil in the trench is excavated, a pressure difference will be generated between the soil on both sides of the trench. The soil on the trench sidewall will move horizontally from the outside to the inside, that is, the soil on the trench sidewall tends to move towards the trench. At this time, the slope protection on both sides of the trench will also be displaced. Currently, it is impossible to observe the amount of slope displacement, make an accurate judgment, and protect and reinforce the slope in time, which is not conducive to the trench construction.

[0004] Therefore, it is necessary to provide a trench slope protection structure to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a trench slope protection structure to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A monitoring enclosure is installed on the slope protection body at the location corresponding to the monitoring through hole, and an actuating rod is movably provided on the monitoring enclosure.

[0011] A steel ruler is installed inside the monitoring enclosure. The upper surface of the steel ruler is marked with graduations and is used in conjunction with the indicator rod to monitor the displacement value of the slope protection body.

[0012] A warning sign is rotatably mounted on the monitoring enclosure to serve as a warning.

[0013] A transmission mechanism, located inside the monitoring enclosure, is used to convert the displacement generated by the trigger rod into rotation of the warning plate through the cooperation of the transmission mechanism and the baffle.

[0014] As a further aspect of the present invention: a movable groove is provided on the inner wall of the monitoring enclosure corresponding to the trigger rod, the trigger rod is slidably connected to the movable groove, and a first elastic element is provided between the movable groove and the trigger rod.

[0015] As a further aspect of the present invention: the monitoring enclosure is provided with a transmission cavity, and the transmission cavity and the moving groove are connected to each other through a connecting groove; the transmission mechanism includes:

[0016] A rotating shaft is rotatably disposed within the transmission cavity, with one end of the rotating shaft extending outside the monitoring enclosure and connected to the warning plate;

[0017] A gear is mounted on the rotating shaft, and a toothed plate that meshes with the gear is slidably provided on the bottom wall of the transmission cavity;

[0018] A connecting block is disposed in the communicating groove, with one end connected to the toothed plate and the other end connected to the actuating rod.

[0019] As a further embodiment of the present invention: a mounting ring is slidably sleeved on the fixing rod, the mounting ring is provided with a mounting outer hole, and the fixing rod is provided with a mounting inner hole. The mounting ring is fixed on the fixing rod by the cooperation of the mounting inner hole and the mounting outer hole. An adjustment seat is provided on the mounting ring, and the baffle is provided on the adjustment seat.

[0020] As a further embodiment of the present invention: the adjusting seat is provided with a through groove running vertically through it, and a U-shaped block connected to the baffle is movably provided on the adjusting seat, and the U-shaped block is provided with a fixing hole that cooperates with the through groove.

[0021] As a further aspect of the present invention, it also includes:

[0022] A sliding groove is provided on the fixed rod and is slidably connected to the indicator rod, so that the indicator rod can move up and down along the sliding groove.

[0023] As a further aspect of the present invention, it also includes:

[0024] Two mounting bases are provided on the inner wall of the monitoring enclosure for mounting the steel ruler. The mounting bases are provided with mounting grooves to restrict the horizontal movement of the steel ruler.

[0025] A limiting component, disposed on the mounting base, is used to limit the vertical movement of the steel ruler.

[0026] As a further aspect of the present invention: the limiting component includes a limiting block movably disposed within the mounting base, a limiting rod movably disposed on the outer wall of the mounting base and connected to the limiting block, a pull block disposed at the outer end of the limiting rod, and a second elastic element disposed between the pull block and the mounting base.

[0027] As a further embodiment of the present invention: the monitoring enclosure is symmetrically hinged with a first positioning plate on both sides, and a second positioning plate is provided on the first positioning plate. Both the first positioning plate and the second positioning plate are provided with positioning holes that are adapted to the fixing rod.

[0028] As a further aspect of the present invention: the first positioning plate is provided with a first stabilizing hole, and the monitoring enclosure is provided with a second stabilizing hole that is compatible with the first stabilizing hole.

[0029] Compared with the prior art, the advantages of this invention are:

[0030] 1. In this scheme, when the slopes on both sides of the trench cause displacement of the revetment, the monitoring plate on the revetment will move the steel ruler accordingly. Since the fixed rod does not move with the displacement of the revetment, the indicator rod on the fixed rod remains stationary. Therefore, after the steel ruler moves, the indicator rod will point to a different scale on the steel ruler. At this time, the displacement of the revetment can be monitored based on the change in the scale on the steel ruler. Furthermore, the displacement of the revetment can be used to determine whether reinforcement of the slopes on both sides of the trench and the revetment is necessary. This allows for timely and accurate reinforcement, greatly improving the safety of trench construction and enhancing the quality of subsequent trench construction. The scheme has good performance.

[0031] 2. In this scheme, when the slope protection body moves synchronously with the monitoring enclosure, the monitoring enclosure will cause the trigger rod to move towards the baffle, while the baffle remains stationary. Once the trigger rod reaches the baffle and stops moving, the monitoring enclosure will continue to drive the transmission mechanism to move. This transmission mechanism will cause the warning plate to rotate from a horizontal to a vertical position, providing timely warning to workers and enabling timely reinforcement. This improves the safety factor and further avoids the need for frequent observation of the monitoring enclosure's position, saving time and effort. It also allows for better monitoring of the slope protection body's displacement and is highly practical.

[0032] 3. In this solution, the U-shaped block can be moved along the adjusting seat before and after use, so that the position of the baffle can be adjusted. The distance between the baffle and the trigger rod can be adjusted according to different allowable displacement ranges. When the allowable displacement range is exceeded, the warning plate will be flipped to remind the user by cooperating with the baffle. It has a wide range of applications, meets the needs of use in different situations, and is highly flexible.

[0033] 4. In this solution, the steel ruler can be installed and disassembled through the cooperation of the mounting base, mounting slot and limiting components. The installation and removal of the steel ruler is very simple and convenient, which greatly facilitates the subsequent replacement or maintenance of the steel ruler, as well as convenient transportation and storage, and has good performance.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Example 1:

[0047] Please see Figure 1-4 and Figure 6 A trench slope protection structure includes a slope protection body 1, and further includes: a monitoring through hole 2, which is vertically oriented through the upper and lower walls of the slope protection body 1; a fixing rod 3, which is located inside the monitoring through hole 2 and does not contact the slope protection body 1, with an indicator rod 6 and a baffle 7 on each side of the fixing rod 3; a monitoring enclosure 4, located on the slope protection body 1 at the corresponding monitoring through hole 2, with an actuating rod 10 movably mounted on the monitoring enclosure 4; a steel ruler 5, located inside the monitoring enclosure 4, with graduations on its upper surface, used to cooperate with the indicator rod 6 to monitor the displacement value of the slope protection body 1; a warning plate 8, rotatably mounted on the monitoring enclosure 4 for a warning function; and a transmission mechanism 9, located inside the monitoring enclosure 4, used to convert the displacement generated by the actuating rod 10 into the rotation of the warning plate 8 through the transmission mechanism 9 and the baffle 7. A cover plate 29, which is made of transparent material, is hinged to the monitoring enclosure 4 for easy observation. The indicator rod 6 is also equipped with scales, so that when the monitoring panel 4 moves the steel ruler 5 to produce lateral displacement, it is convenient to observe the amount of movement.

[0048] A movable groove 11 is provided at the corresponding trigger rod 10 on the inner wall of the monitoring enclosure 4. The trigger rod 10 is slidably connected to the movable groove 11. A first elastic element 12 is provided between the movable groove 11 and the trigger rod 10. The first elastic element 12 in this application is a spring.

[0049] In use, a monitoring through hole 2 is made in the slope protection body 1, and the monitoring enclosure 4 is fixed on the slope protection body 1 and located at the monitoring through hole 2. Then, the fixing rod 3 is placed into the monitoring through hole 2, and the bottom of the fixing rod 3 is fixed in the soil below the slope protection body 1. The fixing rod 3 does not contact the slope protection body 1.

[0050] When the slopes on both sides of the trench shift, the slope protection body 1 will also shift, moving towards the trench. Therefore, the monitoring enclosure 4 on the slope protection body 1 will shift synchronously, and the steel ruler 5 inside the monitoring enclosure 4 will also shift accordingly. Since the fixing rod 3 is inserted into the monitoring through-hole 2 and fixed in the soil at the bottom of the slope protection body 1, the fixing rod 3 does not move with the shift of the slope protection body 1. Therefore, the indicator rod 6 on the fixing rod 3 remains stationary. When the steel ruler 5 moves, the indicator rod 6 will point to a different scale on the steel ruler 5. The displacement of the slope protection body 1 can then be monitored based on the change in the scale on the steel ruler 5. Furthermore, the displacement of the slope protection body 1 can be used to determine whether reinforcement of the slopes on both sides of the trench and the slope protection body 1 is necessary. This allows for direct monitoring of the slope protection body 1's displacement, enabling timely and accurate reinforcement, greatly improving the safety of trench construction, and contributing to the quality of subsequent trench construction. The system offers excellent performance.

[0051] When the slope protection body 1 moves synchronously with the monitoring enclosure 4, the monitoring enclosure 4 will cause the trigger rod 10 to move. The trigger rod 10 moves towards the baffle 7, which is mounted on the fixed rod 3 and does not move. When the trigger rod 10 moves to contact the baffle 7, it stops moving. When the monitoring enclosure 4 continues to move, the trigger rod 10 will compress the first elastic element 12. At this time, the warning plate 8 will rotate through the transmission mechanism 9. The warning plate 8 will gradually rotate from a horizontal state to a vertical state. At this time, the staff can observe the warning plate 8 from a distance, which can serve as a warning to the staff and provide timely reminders and reinforcement. This greatly improves the safety factor and further avoids the need to frequently observe the position of the monitoring enclosure 4, saving time and effort. It can better monitor the displacement of the slope protection body 1, is highly practical, and meets the usage requirements.

[0052] In this embodiment, preferably, please refer to [reference needed]. Figure 2 , Figure 4 and Figure 8 The monitoring enclosure 4 has a transmission cavity 13 inside, which is connected to the moving groove 11 through a connecting groove 14. The transmission mechanism 9 includes: a rotating shaft 91, which is rotatably disposed in the transmission cavity 13, with one end of the rotating shaft 91 extending out of the monitoring enclosure 4 and connected to the warning plate 8; a gear 92, which is disposed on the rotating shaft 91, and a toothed plate 93 that meshes with the gear 92 is slidably disposed on the bottom wall of the transmission cavity 13; and a connecting block 94, which is disposed in the connecting groove 14, with one end connected to the toothed plate 93 and the other end connected to the trigger rod 10. When the slope protection body 1 moves synchronously with the monitoring enclosure 4, the baffle 7 does not move, and the trigger rod 10, the connecting block 94, and the toothed plate 93 do not move. The monitoring enclosure 4 will drive the rotating shaft 91 and the gear 92 to move. When the gear 92 moves along the toothed plate 93, it will rotate, and the rotation of the gear 92 will drive the rotating shaft 91 and the warning plate 8 to rotate.

[0053] In this embodiment, preferably, please refer to [reference needed]. Figure 3 and Figure 6-7 It also includes a chute 20, mounted on the fixed rod 3 and slidably connected to the indicator rod 6, used to allow the indicator rod 6 to move up and down along the chute 20. When the slope protection body 1 is displaced, it will cause the slope protection body 1 to move. When the slope protection body 1 causes the steel ruler 5 to move horizontally, it may also cause vertical displacement, which will cause the steel ruler 5 to move vertically. When the steel ruler 5 moves vertically, it will cause the indicator rod 6 to move vertically along the chute 20, ensuring that the indicator rod 6 is always above the steel ruler 5, guaranteeing accurate and intuitive observation of the changes in the scale on the steel ruler 5. Simultaneously, the indicator rod 6 can be slid out along the chute 20, facilitating disassembly, installation, and replacement, resulting in good performance.

[0054] In this embodiment, preferably, please refer to [reference needed]. Figure 6-7 A mounting ring 15 is slidably sleeved on the fixing rod 3. The mounting ring 15 has an outer mounting hole 151, and the fixing rod 3 has a through mounting inner hole 152. The mounting ring 15 is fixed to the fixing rod 3 by the cooperation of the inner mounting hole 152 and the outer mounting hole 151. The mounting ring 15 has an adjusting seat 16, and the baffle 7 is located on the adjusting seat 16. By sliding the mounting ring 15 onto the fixing rod 3, the outer mounting hole 151 on the mounting ring 15 corresponds to the inner mounting hole 152 at a designated position on the fixing rod 3. Then, by passing a fixing bolt through the outer mounting hole 151 and the inner mounting hole 152, and fixing it with a nut, the mounting ring 15 can be fixed in an appropriate position on the fixing rod 3. The height of the mounting ring 15 can be adjusted according to the specific situation, that is, the height of the baffle 7 on the fixing rod 3 can be adjusted, so that after the fixing rod 3 is fixed, the baffle 7 can be in an appropriate position, that is, on the side of the trigger rod 10. It is highly flexible and has a wide range of applications.

[0055] In this embodiment, preferably, please refer to [reference needed]. Figure 6-7 The adjusting seat 16 has a through groove 17 running vertically through it. A U-shaped block 18 connected to the baffle 7 is movably mounted on the adjusting seat 16. The U-shaped block 18 has a fixing hole 19 that mates with the through groove 17. Before and after use, the U-shaped block 18 can be moved along the adjusting seat 16, allowing the baffle 7 to adjust its position. This allows the distance between the baffle 7 and the trigger rod 10 to be adjusted according to different allowable displacement ranges. When the allowable displacement range is exceeded, the baffle 7 will trigger the warning plate 8 to flip and provide a warning. This design has a wide range of applications, meets the needs of different situations, and is highly flexible. After adjustment, the U-shaped block 18 and the baffle 7 can be fixed to the adjusting seat 16 by passing bolts through the fixing hole 19 on the U-shaped block 18 and the through groove 17 on the adjusting seat 16, and then securing them with nuts. This design is simple and convenient to operate, and also allows for easy disassembly and replacement of the baffle 7, resulting in good performance.

[0056] Example 2:

[0057] Based on Example 1, please refer to Figure 2 and Figure 5 It also includes: two mounting bases 21, located on the inner wall of the monitoring enclosure 4, for mounting a steel ruler 5. Each mounting base 21 has a mounting groove 22 to restrict the horizontal movement of the steel ruler 5. A limiting component 23, located on the mounting base 21, is used to restrict the vertical movement of the steel ruler 5. The limiting component 23 includes a limiting block 231 movably disposed within the mounting base 21, a limiting rod 232 movably disposed on the outer wall of the mounting base 21 and connected to the limiting block 231, a pull block 233 at the outer end of the limiting rod 232, and a second elastic element 234 between the pull block 233 and the mounting base 21. When the steel ruler 5 is installed on the monitoring enclosure 4, it is placed directly into the mounting slots 22 on the mounting seats 21 on both sides. This restricts the steel ruler 5 horizontally, causing it to press against the limiting block 231. The limiting block 231 moves inward toward the mounting seat 21, simultaneously driving the limiting rod 232 and the pull block 233 outward and stretching the second elastic element 234. Eventually, the steel ruler 5 enters the mounting seat 21, and then moves below the limiting block 231 without pressing against it. The second elastic element 234 then drives the limiting rods 232 and the limiting block 231 on both sides to move closer to each other, thus restoring the limiting block 231 to its initial position. At this point, the limiting block 231 is above the steel ruler 5, which restricts and fixes the steel ruler 5 vertically, thus completing the installation of the steel ruler 5. When it is necessary to remove the steel ruler 5, the pull block 233 can be pulled to move the limiting rod 232 and the limiting block 231. The limiting block 231 will eventually enter the mounting base 21. At this time, the limiting block 231 no longer restricts the steel ruler 5, and the steel ruler 5 can be taken out from the mounting slot 22, thus completing the disassembly. Therefore, the installation and removal of the steel ruler 5 is very simple and convenient, which greatly facilitates the subsequent replacement or maintenance of the steel ruler 5, as well as convenient transportation and storage, and has a good effect.

[0058] Example 3:

[0059] Based on Example 1, please refer to Figure 1-2 and Figure 9 The monitoring enclosure 4 has two symmetrically hinged first positioning plates 24 on both sides. A second positioning plate 25 is provided on the first positioning plate 24. Both the first positioning plate 24 and the second positioning plate 25 have positioning holes 26 that match the fixing rod 3. To ensure the fixing rod 3 is positioned as close to the center of the monitoring through hole 2 as possible, and to reduce interference from the slope protection body 1 to the fixing rod 3, the first positioning plates 24 and the second positioning plates 25 can be flipped, causing them to rotate towards each other, ultimately bringing the two first positioning plates 24 and the second positioning plates 25 together. Figure 9As shown, the fixing rod 3 can be inserted into the monitoring through hole 2 along the positioning holes 26 on the first positioning plate 24 and the second positioning plate 25 and inserted into the soil. The two positioning holes 26 can keep the fixing rod 3 in a central position, which greatly avoids the fixing rod 3 from being tilted or too close to the inner wall of the monitoring through hole 2, which would cause interference or affect the subsequent monitoring effect. The effect is good. After the fixing rod 3 is installed, the first positioning plate 24 and the second positioning plate 25 on both sides are flipped in the opposite direction so that they are flush with the monitoring enclosure 4, and then the cover plate 29 is put on.

[0060] In this embodiment, preferably, please refer to [reference needed]. Figure 2 The first positioning plate 24 has a first stabilizing hole 27, and the monitoring enclosure 4 has a second stabilizing hole 28 that matches the first stabilizing hole 27. After the first positioning plate 24 is flipped onto the monitoring enclosure 4, as... Figure 9 As shown, the first positioning plate 24 can be fixed to the monitoring enclosure 4 by screwing bolts into the first stabilizing hole 27 and the second stabilizing hole 28 respectively, which can improve the stability when the fixing rod 3 is subsequently placed.

[0061] Working principle: In use, a monitoring through-hole 2 is made in the slope protection body 1. The monitoring enclosure 4 is fixed to the slope protection body 1 at the position of the monitoring through-hole 2. Then, the fixing rod 3 is placed into the monitoring through-hole 2, with the bottom of the fixing rod 3 fixed in the soil below the slope protection body 1, and the fixing rod 3 does not contact the slope protection body 1. In order to make the fixing rod 3 as close to the middle of the monitoring through-hole 2 as possible and reduce the interference of the slope protection body 1 with the fixing rod 3, the first positioning plate 24 and the second positioning plate 25 can be flipped so that the two first positioning plates 24 and the second positioning plate 25 on both sides are flipped in the same direction, so that the two first positioning plates 24 and the second positioning plate 25 are finally put together, such as Figure 9 As shown, the fixing rod 3 can be inserted into the monitoring through hole 2 along the positioning holes 26 on the first positioning plate 24 and the second positioning plate 25 and inserted into the soil. The two positioning holes 26 can keep the fixing rod 3 in a central position, which greatly avoids the fixing rod 3 from being tilted or too close to the inner wall of the monitoring through hole 2, which would cause interference or affect the subsequent monitoring effect. The effect is good. After the fixing rod 3 is installed, the first positioning plate 24 and the second positioning plate 25 on both sides are flipped in the opposite direction so that they are flush with the monitoring enclosure 4, and then the cover plate 29 is put on.

[0062] When the slopes on both sides of the ditch shift, the slope protection body 1 will also shift, moving towards the ditch. Therefore, the monitoring enclosure 4 on the slope protection body 1 will shift synchronously, and the steel ruler 5 inside the monitoring enclosure 4 will also shift accordingly. Since the fixing rod 3 is inserted into the monitoring through-hole 2 and fixed in the soil at the bottom of the slope protection body 1, the fixing rod 3 does not move with the shift of the slope protection body 1. Therefore, the indicator rod 6 on the fixing rod 3 remains stationary. As the steel ruler 5 moves, the indicator rod 6 will point to a different scale on the steel ruler 5, and the displacement of the slope protection body 1 can be monitored based on this change in scale.

[0063] When the slope protection body 1 moves synchronously with the monitoring enclosure 4, the monitoring enclosure 4 will move the trigger rod 10. The trigger rod 10 moves towards the baffle 7, which is mounted on the fixed rod 3 and does not move. When the trigger rod 10 moves to contact the baffle 7, it stops moving. When the monitoring enclosure 4 continues to move, the trigger rod 10 will compress the first elastic element 12. At this time, the trigger rod 10, the connecting block 94, and the toothed plate 93 do not move. The monitoring enclosure 4 will move the rotating shaft 91 and the gear 92. When the gear 92 moves along the toothed plate 93, it will rotate. The rotation of the gear 92 will drive the rotating shaft 91 and the warning plate 8 to rotate. The warning plate 8 will gradually rotate from a horizontal state to a vertical state. At this time, the staff can observe the warning plate 8 from a distance, which can serve as a warning to the staff, provide timely reminders, and carry out timely reinforcement, greatly improving the safety factor.

[0064] Before and after use, the U-shaped block 18 can be moved along the adjusting seat 16, allowing the baffle 7 to adjust its position. This adjusts the distance between the baffle 7 and the trigger rod 10 according to different allowable displacement ranges. When the allowable displacement range is exceeded, the baffle 7 triggers the warning plate 8 to flip and provide a warning. This design is widely applicable, meets the needs of different situations, and offers high flexibility. After adjustment, bolts are passed through the fixing holes 19 on the U-shaped block 18 and the through slots 17 on the adjusting seat 16, and then secured with nuts to fix the U-shaped block 18 and the baffle 7 to the adjusting seat 16.

[0066] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
