[0001] The present invention relates to the technical field of support warning, and more specifically, it relates to a deep foundation pit support warning system. Background Technique

[0002] A deep foundation pit refers to a project with a excavation depth exceeding five meters or more than three basement floors, or although the depth does not exceed five meters, but the geological conditions, surrounding environment and underground pipelines are particularly complex.

[0010] As a further optimization solution of the present invention, the connecting block is connected to the end of the moving rod through an elastic member.

[0011] As a further optimization solution of the present invention, a notch ring is installed at the end of the moving rod, and the distance between the notch ring and the connecting block is the distance required for the button to be turned on and pressed.

[0013] As a further optimized solution of the present invention, the mobile terminal is a mobile phone terminal and multiple are provided.

[0014] The beneficial effects of the present invention are as follows: 1. For the deep - foundation - pit support warning system of the present invention, multiple support piles are connected through a protection mechanism. When one - side support pile is affected by the foundation pit, the force can be transmitted to the adjacent - side support pile, realizing the sharing of pressure together, making the cooperation of each support pile closer, greatly enhancing the integrity and stability of the support structure, effectively improving the bearing capacity of the overall support structure, reducing the force on a single support pile, and reducing the risk of tilting and collapse.

[0015] 2. For the deep - foundation - pit support warning system of the present invention, through the coordinated action of the protection mechanism and multiple support piles, the support piles on each side are connected to each other, increasing the integrity of the support piles on each side and enhancing the support effect. When the steel wire rope is pulled by the action of the foundation pit, due to the setting of the moving plate, there is oil on both sides of it, which plays a role in limiting the position of the broken steel wire rope, reducing the phenomenon of damage to surrounding components due to the breakage of the steel wire rope. At the same time, when the steel wire rope breaks, the remaining steel wire ropes are under the action of the moving plate and are also in a taut state, so that the support piles can carry out stable support.

[0016] 3. For the deep - foundation - pit support warning system of the present invention, when arranging the support piles, they can be flexibly arranged according to the actual size of the foundation pit. To further improve the stability of the support structure, steel wire ropes are arranged between the support piles and adjusting parts are equipped. With the help of the adjusting parts, the tension degree of the steel wire ropes can be adjusted, making the connection between the support piles closer, effectively enhancing the overall performance of the support system. In addition, the setting of this kind of support pile can adapt to foundation pits of various scales, greatly improving the reusability of the support piles and meeting the diverse requirements of foundation - pit support.

[0017] 4. For the deep - foundation - pit support warning system of the present invention, the auxiliary pile is connected to the protection mechanism through a guiding mechanism. When the protection mechanism moves due to the force on the support pile, it triggers the alarm mechanism to send an alarm, timely reminding the staff that there is an abnormality in the deep - foundation - pit support structure, facilitating timely measures to be taken to ensure construction safety, realizing the timely warning of abnormal situations in the deep - foundation - pit support and improving the safety - guarantee function.

[0018] 5. In the deep foundation pit support warning system of the present invention, by providing a self-adaptive blocking mechanism, the stability of the foundation pit support is enhanced. When the local part of the foundation pit sinks, the auxiliary column increases the length outside the support pile, and the downward movement after the flipping of the connecting plate forms an additional blocking space, effectively protecting the area between adjacent auxiliary columns and significantly reducing the risk of the inward collapse of the foundation pit.

[0034] Now, the subject matter described herein will be discussed with reference to exemplary embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the protection scope of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. In addition, the features described in some examples can also be combined in other examples

[0035] Embodiment 1 As Figure 1 and Figure 14 shown, a deep foundation pit support warning system according to an embodiment of the present invention includes a system processing module, a cloud server, a mobile terminal, a web terminal, a support module, and an alarm mechanism 5. The mobile terminal is a mobile phone terminal, and multiple mobile terminals are provided The alarm mechanism 5 is arranged on the support module to give an alarm when the support module changes The alarm mechanism 5 is connected to the cloud server to send the monitoring data to the cloud server. The cloud server sends the data to the mobile terminal and the web terminal through the web terminal to achieve multi-terminal warning information synchronization The support module includes a support pile 1, a protection mechanism 2, an auxiliary pile 3, and a guide mechanism 4 A rectangular enclosure area for enclosing the foundation pit is formed between multiple support piles 1 The upper regions of the support piles 1 are connected to each other through the protection mechanism 2. When one of the support piles 1 on one side of the rectangular enclosure area is affected by the foundation pit, the adjacent support piles 1 provide additional support and protection to the side affected by the foundation pit through the protection mechanism 2 Auxiliary piles 3 are provided outside the diagonal corners of the rectangular enclosure area, and the auxiliary piles 3 are connected to the protection mechanism 2 through a guiding mechanism 4; An alarm mechanism 5 is arranged on the guiding mechanism 4 so that when the protection mechanism 2 moves under the action of the foundation pit, the alarm mechanism 5 is triggered to respond.

[0036] It should be noted that in the scenario of deep foundation pit support, the support piles 1 form a rectangular enclosure area to preliminarily enclose the foundation pit. When one side of the support piles 1 has a displacement trend towards the inside of the foundation pit under the pressure of the foundation pit, the protection mechanism 2 comes into play. It will transfer the force on this side to the support piles 1 in the adjacent area, enabling each support pile 1 to share the pressure together, thereby enhancing the overall support stability. Multiple support piles 1 work together, effectively improving the bearing capacity of the overall support structure, reducing the force on a single-side support pile 1, and greatly reducing the risk of tilting and collapse.

[0037] At the same time, the auxiliary piles 3 are connected to the protection mechanism 2 through the guiding mechanism 4 to play an auxiliary support role. Once the protection mechanism 2 moves due to the force on the support piles 1, it will drive the guiding mechanism 4 to act, thereby triggering the alarm mechanism 5. This cooperation mechanism can timely warn of potential dangers, enabling the staff to detect possible safety hazards in advance and providing a strong guarantee for construction safety.

[0038] Refer to Figure 2 For the content, specifically, the protection mechanism 2 includes auxiliary columns 21, steel wire ropes 22, rotating columns 23 and rotating blocks 24. The rotating columns 23 are slidably inserted into the support piles 1 at the diagonal corners and are fixedly connected to the rotating blocks 24. The rotating blocks 24 are installed on the rotating columns 23 in a diagonal area. The auxiliary columns 21 are slidably inserted into the remaining support piles 1. Both ends of the steel wire rope 22 respectively pass through the support piles 1 on the adjacent sides and the rotating columns 23 at the diagonal corners, and wind around the auxiliary columns 21 and are connected to the rotating blocks 24. An adjusting member for adjusting the tension of the steel wire rope 22 is provided on the rotating block 24.

[0039] The number of rotating blocks 24 is two. Two sides of one rotating block 24 are respectively connected to both ends of a steel wire rope 22. Refer to Figure 13 For the content, it can be seen the path where the steel wire rope 22 (dashed line indicates) is arranged.

[0040] It should be noted that when one side of the support piles 1 is affected by the foundation pit, the support piles 1 tend to move inward, the steel wire rope 22 will be pulled, and then the steel wire rope 22 (the remaining part of one steel wire rope 22) in the adjacent side support piles 1 will be pulled. These steel wire ropes 22 then transfer the force to the side support piles 1 to achieve the dispersion and transfer of the force.

[0041] Through the cooperation of the steel wire rope 22, the rotating column 23 and the rotating block 24, the cooperation of each supporting pile 1 becomes closer, greatly enhancing the integrity and stability of the supporting structure. In the entire deep foundation pit supporting system, the internal force transmission and sharing mechanism of the protection mechanism 2 further improves the overall force conduction process. The force on the supporting pile 1 is transmitted to the supporting piles 1 on other sides through the steel wire rope 22, dispersing the force to other steel wire ropes 22 and supporting piles 1, providing a reliable supporting effect for the deep foundation pit and effectively ensuring the safety of the deep foundation pit construction.

[0042] Referring to Figure 2 and Figure 6 the content, a casing 25 located outside the steel wire rope 22 is provided between adjacent auxiliary columns 21. Both ends of the casing 25 are slidably sleeved with inserting pipes 26. One end of the inserting pipe 26 slides into the interior of the auxiliary column 21. A moving plate 27 is fixedly sleeved on the steel wire rope 22. The moving plate 27 is connected to the inserting pipe 26 through a return spring 28. A valve 216 is provided on the casing 25.

[0043] After inserting the inserting pipe 26 into the interior of the auxiliary column 21, a part of the oil fluid is pre-injected into the inserting pipe 26 and the casing 25. When adjusting the tension of the steel wire rope 22 through the adjusting member, if the steel wire rope 22 breaks due to excessive adjustment, when the moving plate 27 moves along with the action of the steel wire rope 22, due to the action of the oil fluid, it plays a blocking role, reducing the damage caused by the whipping of the steel wire rope 22 to the surrounding components. After adjusting the tension of the steel wire rope 22 through the adjusting member, oil fluid is respectively injected into the space enclosed by the casing 25 and the inserting pipe 26 through the valve 216 to fill the enclosed space, making the position of the moving plate 27 stable, thereby limiting the position of the steel wire rope 22. When the steel wire rope 22 breaks during support, since the moving plate 27 is affected by the oil fluid on both sides and cannot move, the broken steel wire rope 22 has less impact on other components when breaking, so that after one break, the steel wire ropes 22 at other places are still in a tightened state for stable support.

[0044] The inserting pipe 26 is inserted into the interior of the auxiliary column 21. With the use of the casing 25, the supporting piles 1 in each side area of the rectangular enclosure area are connected, causing each side area to form a stable blocking area respectively, increasing the stability of the block.

[0045] As a further optimization scheme of the present invention, referring to Figure 12Regarding the content, the adjusting member includes a T-shaped rotating rod 29, a mounting disk 210, a gear disk 212, an internal gear ring 213, a connecting rod 214, and a positioning pin 215. The mounting disk 210 is fixedly sleeved on the auxiliary pile 3. The T-shaped rotating rod 29 is connected to the rotating block 24 through the gear disk 212. The internal gear ring 213 is slidably sleeved on the outer periphery of the gear disk 212 and meshes with the gear disk 212. One end of the connecting rod 214 is fixedly connected to the internal gear ring 213. The positioning pin 215 slidably passes through the connecting rod 214 and extends into the interior of the mounting disk 210.

[0046] When supporting foundation pits of different lengths and widths, since different numbers of supporting piles 1 need to be set, in order to recycle the supporting piles 1, by rotating the T-shaped rotating rod 29, the T-shaped rotating rod 29 drives the gear disk 212 to rotate, so as to tension and adjust the steel wire rope 22, increase the tightness between the supporting piles 1, and at the same time facilitate adapting to foundation pits of different sizes.

[0047] Under the action of the connecting rod 214, it plays a role in connecting with the mounting disk 210 to limit the supporting piles 1 at the diagonal corners, increase their positions, and thus increase the stability of the support.

[0048] Refer to Figures 3 to 5 and Figure 8 Regarding the content, the guiding mechanism 4 includes a sleeve 41, a moving rod 42, a universal joint 43, and a steel wire cable 44. The sleeve 41 is installed on the auxiliary pile 3. One end of the moving rod 42 slidably extends into the interior of the sleeve 41. One end of the steel wire cable 44 is connected to the auxiliary column 21 through the universal joint 43, and the other end acts on the moving rod 42 through the universal joint 43 to make the moving rod 42 extend into the sleeve 41.

[0049] The steel wire cable 44 can connect the supporting piles 1 in the area close to the middle according to the size of the foundation pit.

[0050] When the supporting pile 1 is stressed and causes the protection mechanism 2 to move, the auxiliary column 21 will move accordingly. The auxiliary column 21 drives the steel wire cable 44 to move through the universal joint 43, and the steel wire cable 44 pulls the moving rod 42 to slide into the sleeve 41 through the universal joint 43, playing a guiding role.

[0051] Refer to Figures 3 to 5 , Figure 8 and Figure 9Content, the alarm mechanism 5 includes a button 51, an audible and visual alarm 52, a power supply module 53, a connecting block 54 and a plug rod 55. The power supply module 53 forms a loop between the audible and visual alarm 52 and the button 51. The button 51 is installed at the end of the moving rod 42. One end of the plug rod 55 slides into the interior of the moving rod 42, and the other end is connected to the steel wire cable 44 through the connecting block 54. The connecting block 54 is connected to the end of the moving rod 42 through an elastic member 56 (the elastic member 56 is a spring or a shrapnel). A notch ring 57 is assembled at the end of the moving rod 42. The distance between the notch ring 57 and the connecting block 54 enables the button 51 to be turned on when pressed within this distance. The notch ring 57 defines the displacement amount for alarm triggering, further improving the accuracy and adjustability of alarm triggering.

[0052] The button 51 is a push-to-conduct button, which is a prior art and will not be elaborated here.

[0053] The retaining pile 1 continuously moves under the action of the foundation pit, which will cause the protective mechanism 2 to move, and then drive the guiding mechanism 4 to act. Specifically, the moving rod 42 slides into the sleeve 41 under the action of the steel wire cable 44. The connecting block 54 drives the plug rod 55 to continuously insert into the moving rod 42. When the connecting block 54 continuously moves towards the moving rod 42, it presses the button 51 until the connecting block 54 is blocked by the notch ring 57, then the button 51 is in a conducting state. At this time, the loop formed by the power supply module 53, the audible and visual alarm 52 and the button 51 is turned on, and the audible and visual alarm 52 is powered on to emit an alarm. This mechanism can timely remind the staff that there is an abnormal situation in the deep foundation pit retaining structure, facilitating the staff to take corresponding measures in time, effectively ensuring the construction safety, realizing the timely warning of the abnormal situation of the deep foundation pit retaining, improving the safety guarantee function of the entire deep foundation pit retaining system. Along with the extrusion of the connecting block 54 and the notch ring 57, the moving rod 42 continuously extends into the interior of the sleeve 41.

[0054] Refer to Figure 7 , and a toggle block 211 for moving the insertion tube 26 is installed on the insertion tube 26.

[0055] The insertion tube 26 can be moved by means of the toggle block 211. By pushing the insertion tube 26 with the toggle block 211, the length of the insertion tube 26 entering the interior of the sleeve 25 is increased, which is conducive to the connection or separation of the insertion tube 26 and the auxiliary column 21.

[0056] The retaining method includes the following steps: S1. Tightening adjustment: Insert the intubation tube 26 into the interior of the auxiliary column 21. First, pass oil into the interior of the sleeve 25 through the valve 216. The intubation tube 26 is not filled with oil. Rotate the T-shaped rotating rod 29 to drive the rotating block 24 to rotate through the gear disk 212, so as to tighten the steel wire rope 22. Place the internal gear ring 213 on the outer periphery of the gear disk 212, and pass oil into the interior of the sleeve 25 through the valve 216; S2. Micro-deformation support: When one of the support piles 1 in the rectangular enclosure area is affected by the foundation pit, the support pile 1 acts on the adjacent side support pile 1 through the steel wire rope 22; S3. Continuous inclination: The support pile 1 continuously inclines, pulls the connecting block 54 through the steel wire rope 44, the connecting block 54 presses the button 51, and the sound and light alarm 52 responds for response reminder.

[0057] Embodiment 2 Refer to Figure 10 and Figure 11 content. On the basis of Embodiment 1, it further includes a self-adaptive blocking mechanism 6. The self-adaptive blocking mechanism 6 includes a support frame 61, a connecting plate 62 and a protection plate 63. The support frame 61 is placed on the top of the support pile 1 and fixedly connected to the auxiliary column 21. One end of the connecting plate 62 slides through the support frame 61 and is fixedly connected to the top end of the support pile 1, and the other end is rotatably connected to the protection plate 63 through a hinge. A positioning rod 64 is slidably inserted into the protection plate 63.

[0058] It should be noted that the positioning rod 64 can be inserted into the soil during use to limit the radial position of the auxiliary column 21 through the protection plate 63 and the connecting plate 62, increasing the stability of the position of the auxiliary column 21. The support frame 61 plays a role in stabilizing multiple auxiliary columns 21. When the local part of the foundation pit sinks, the local support pile 1 sinks, then the auxiliary column 21 continuously increases the length located outside to play a role in radial blocking. At the same time, the top surface of the soil area corresponding to the sunken support pile 1 also sinks. The sunken support pile 1 drives the connecting plate 62 to flip to a vertical state and continuously move down to form a blocking space to protect the area between two adjacent auxiliary columns 21, thereby reducing the phenomenon of danger caused by the inward collapse of the foundation pit (the height difference between the non-sunken area and the sunken area increases the risk of collapse).

[0059] Working principle: Installation and preparation: Before construction, according to the design requirements, the support piles 1 are driven into the ground to form a rectangular enclosure area, initially enclosing the foundation pit. Then, a protective mechanism 2 is installed on the top of the support piles 1, and the auxiliary columns 21, steel wire ropes 22, rotating columns 23, and rotating blocks 24 are connected and fixed. Auxiliary piles 3 are driven outside the diagonal corners of the rectangular enclosure area and connected to the protective mechanism 2 through a guiding mechanism 4. At the same time, an alarm mechanism 5 is installed. After inserting the insertion tube 26 into the auxiliary column 21, a part of the oil is pre-injected into the insertion tube 26 and the sleeve 25. When adjusting the tension of the steel wire rope 22 through the adjusting member, if the steel wire rope 22 breaks due to excessive adjustment, when the moving plate 27 moves along with the action of the steel wire rope 22, due to the action of the oil, it plays a blocking role, reducing the damage caused by the whipping of the steel wire rope 22 to the surrounding components. After adjusting the tension of the steel wire rope 22 through the adjusting member, oil is respectively injected into the space enclosed by the sleeve 25 and the insertion tube 26 through the valve 216 to fill the enclosed space, making the position of the moving plate 27 stable, thereby limiting the position of the steel wire rope 22. When the steel wire rope 22 breaks during support, since the moving plate 27 cannot move due to the action of the oil on both sides, the broken steel wire rope 22 reduces the impact on other components when it breaks, so that after one break, the remaining steel wire ropes 22 are still in a taut state for stable support. By rotating the T-shaped rotating rod 29, the rotating block 24 is driven to rotate to adjust the tension of the steel wire rope 22.

[0060] Micro-deformation support stage: When one side of the support pile 1 in the rectangular enclosure area is subjected to the pressure of the foundation pit and has a tendency to displace into the foundation pit, this support pile 1 will act on the steel wire rope 22, and the steel wire rope 22 will act on the rotating block 24. Since the rotating block 24 is fixed to the rotating column 23 and the rotating column 23 rotates on the support pile 1, the rotating block 24 rotates accordingly. The rotating rotating block 24 pulls the steel wire ropes 22 connected to it in other directions, and these steel wire ropes 22 then transfer the force to the corresponding support piles 1, enabling the remaining support piles 1 in the rectangular enclosure area to jointly participate in the support and share the pressure. During this process, after the insertion tube 26 is inserted into the auxiliary column 21, oil is respectively injected into the space enclosed by the sleeve 25 and the insertion tube 26 through the valve 216, making the position of the moving plate 27 stable, thereby limiting the position of the steel wire rope 22. When the steel wire rope 22 is adjusted in tension by the adjusting member or breaks during support, since the moving plate 27 cannot move due to the action of the oil on both sides, the broken steel wire rope 22 reduces the impact on other components when it breaks, so that after one break, the remaining steel wire ropes 22 are still in a taut state for stable support.

[0061] Continuous inclination stage: If the retaining pile 1 continuously inclines, the auxiliary column 21 in the protection mechanism 2 will move accordingly. The auxiliary column 21 drives the connecting block 54 to move through the universal joint 43. The connecting block 54 drives the insertion rod 55 to slide in the moving rod 42. The connecting block 54 is connected to the end of the moving rod 42 through the elastic member 56. When the connecting block 54 moves to contact the notch ring 57, the button 51 is pressed, so that the circuit formed by the power supply module 53, the sound and light alarm 52 and the button 51 is turned on. The sound and light alarm 52 is powered on to give an alarm, reminding the staff that there is an abnormality in the deep foundation pit retaining structure, so as to take measures in time to ensure the construction safety. The steel wire rope 44 pulls the moving rod 42 to slide into the sleeve 41 by means of the universal joint 43.

[0062] The above describes the embodiments of the present invention, but these embodiments are not limited to the above specific implementation manners. The above specific implementation manners are merely illustrative rather than restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of this embodiment.
