Description

Technical Field

[0001] The present invention relates to the technical field of foundation pit slope protection, and particularly to a slope protection structure for preventing soil collapse in a geotechnical engineering foundation pit. Background Technique

[0002] The slope protection structure for preventing soil collapse in a geotechnical engineering foundation pit is an important measure to ensure the stability of the slope during the foundation pit excavation process and prevent soil collapse.

[0003] However, when the existing slope protection structures for preventing soil collapse in geotechnical engineering foundation pits are in use, most of them support the slopes of the foundation pits. However, the soil around the foundation pit may have insufficient compactness, which affects the effect of anti-collapse support. At the same time, rainwater is easily infiltrated into the soil around the foundation pit, resulting in internal water accumulation, which also affects the effect of anti-collapse support. Moreover, excessive loads may be accumulated on the soil around the foundation pit, and slope instability may also be caused by overloading, which also affects the effect of anti-collapse protection.

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1 - 13, A slope protection structure for preventing soil collapse in a geotechnical foundation pit shown in the figure, including a bottom plate 1 and a support plate 11. A plug rod 12 is fixedly connected to the bottom of the bottom plate 1, and a plurality of inclined supports 13 are arranged between the bottom plate 1 and the support plate 11. The inclined supports 13 are well-known technologies in this technical field and will not be elaborated here. The side wall of the support plate 11 is connected to a U-shaped plate 16 through a lifting mechanism, and the bottom of the U-shaped plate 16 is connected to a first moving plate 14 through a pressure detection mechanism. The bottom of the first moving plate 14 is connected to a pressing plate 15 through a first telescopic mechanism. A plurality of through holes 20 arranged in an array are opened at the bottom of the pressing plate 15. A plug tube 17 is inserted into each through hole 20, and a sharp cone 1701 is arranged at the bottom of the plug tube 17. The first moving plate 14 is fixedly sleeved on the side wall of the plug tube 17, and the top of the first moving plate 14 is connected to a bearing plate 18 through a second telescopic mechanism. The side wall of the bearing plate 18 is rotationally connected to a U-shaped slope plate 19 through a rotating mechanism. A drainage mechanism is arranged on the side wall of the plug tube 17, which can detect the compactness of the soil around the foundation pit. At the same time, a plurality of plug tubes 17 are inserted into the soil to ensure higher compactness of the soil around the foundation pit; when the load above the soil around the foundation pit is too heavy, it can remind the staff; it is convenient to drain the accumulated water in the soil around the foundation pit, so as to make the effect of preventing soil collapse better.

[0034] The pressure detection mechanism includes two symmetrically arranged first sleeve rods 805 fixedly connected to the bottom of the U-shaped plate 16. The side wall of each first sleeve rod 805 is sleeved with a first sleeve 804. The lower end of the first sleeve 804 is fixedly connected to the top of the first moving plate 14. The side wall of each first sleeve 804 is sleeved with a first spring 806. The top of the first moving plate 14 is rotationally connected to a pointer 801 through a rotating component. A first connecting plate 802 is fixedly connected to the side wall of the first moving plate 14, and an arc-shaped scale plate 803 is fixedly connected to the side wall of the first connecting plate 802. When the pressing plate 15 abuts against the soil around the foundation pit, it can compact the surface soil. At the same time, the second spring 203 is gradually compressed. When the U-shaped plate 16 continues to move downward, it can drive the first moving plate 14 to continue to move downward through the pressure detection mechanism, and drive the plug tube 17 and the moving column 303 to move downward synchronously. When the sharp cone 1701 abuts against the soil, it can gradually insert the plug tube 17 into the soil, so as to reinforce the soil around the foundation pit, improve the effect of preventing soil collapse support. And when the plug tube 17 is gradually inserted into the soil, the first spring 806 is gradually compressed. At this time, the distance between the U-shaped plate 16 and the first moving plate 14 gradually becomes smaller. At the same time, the pointer 801 is driven to rotate downward through the rotating component. At this time, by observing the scale plate 803 indicated by the pointer 801, the extrusion force received by the first spring 806 can be determined, and then the compactness of the soil around the foundation pit can be detected. When the indicated scale is small, it means that the compactness of the soil around the foundation pit is insufficient.

[0035] The drainage mechanism includes pumping holes 301 formed in the side walls of each insertion tube 17. A filter screen and a first one-way valve are arranged in the pumping holes 301. The conduction direction of the first one-way valve is from the outside to the inside of the insertion tube 17. A moving column 303 is slidably connected to the inside of the insertion tube 17 through a lifting component. The top of the first moving plate 14 is fixedly connected with an L-shaped block 305. A water collecting pipe 306 is fixedly connected to the side wall of the L-shaped block 305. A drain pipe 307 is fixedly connected to the side wall of the water collecting pipe 306. A plurality of hoses 304 arranged in an array are fixedly inserted into the side wall of the water collecting pipe 306. The bottom of each hose 304 is fixedly connected with a plurality of water outlet pipes 302 arranged in an array. The water outlet pipes 302 are fixedly inserted into the top of the moving column 303 and penetrate to the bottom of the moving column 303. A second one-way valve is arranged in the water outlet pipe 302. The conduction direction of the second one-way valve is from the insertion tube 17 to the hose 304. During use, in rainy weather, when the water content in the soil around the foundation pit is relatively high, the lifting component drives a plurality of moving columns 303 to move up and down reciprocally along the insertion tubes 17. When the moving column 303 moves upward, a negative pressure can be generated inside the insertion tube 17. At the same time, the first one-way valve opens and the second one-way valve closes. At this time, the water in the soil around the foundation pit can enter the insertion tube 17 through the pumping holes 301. When the moving column 303 moves downward, the water inside the insertion tube 17 can be squeezed. At the same time, the first one-way valve closes and the second one-way valve opens. Thus, the water inside the insertion tube 17 can be squeezed and enter the hose 304 through the water outlet pipe 302, and then enter the water collecting pipe 306 and be discharged through the drain pipe 307, so as to facilitate the discharge of the accumulated water in the soil around the foundation pit and make the anti-collapse protection effect better.

[0036] The rotation component includes a fixed plate 901 fixedly connected to the top of the first moving plate 14. The pointer 801 is rotatably connected to the side wall of the fixed plate 901 through a first rotating shaft 902. A sliding groove 903 is formed in the side wall of the pointer 801. A first connecting block 904 is fixedly connected to the side wall of the U-shaped plate 16. A pushing pin 905 is fixedly connected to the side wall of the first connecting block 904. The pushing pin 905 is inserted into the sliding groove 903. When the distance between the U-shaped plate 16 and the first moving plate 14 gradually decreases, the first connecting block 904 can drive the pushing pin 905 to slide along the sliding groove 903, thereby pushing the pointer 801 to rotate downward along the first rotating shaft 902.

[0037] The first telescopic mechanism includes two symmetrically arranged second sleeve rods 201 fixedly connected to the bottom of the first moving plate 14. A second sleeve 202 is sleeved on the side wall of each second sleeve rod 201. The lower end of the second sleeve 202 is fixedly connected to the top of the extrusion plate 15. A second spring 203 is sleeved on the side wall of each second sleeve 202. When the extrusion plate 15 abuts against the soil around the foundation pit, the soil on the surface can be compacted. At the same time, the second spring 203 is gradually compressed.

[0038] The lifting mechanism includes a liquid storage cavity 401 formed in the side wall of the support plate 11, and the liquid storage cavity 401 is filled with hydraulic oil. A second moving plate 402 is connected in the liquid storage cavity 401 through a moving mechanism. An L-shaped pipe 403 is fixedly inserted into the side wall of the liquid storage cavity 401. A moving rod 404 is inserted into the L-shaped pipe 403. A second connecting block 405 is fixedly connected between the lower end of the moving rod 404 and the U-shaped plate 16. Two symmetrically arranged first T-shaped guide rods 407 are fixedly connected to the top of the U-shaped plate 16. A second connecting plate 406 is sleeved on the side wall of the first T-shaped guide rod 407, and the second connecting plate 406 is hinged to the side wall of the support plate 11. It can detect the compactness of the soil around the foundation pit. At the same time, a plurality of insertion pipes 17 are inserted into the soil to ensure higher compactness of the soil around the foundation pit. When the load above the soil around the foundation pit is too heavy, it can remind the staff. It is convenient to drain the accumulated water in the soil around the foundation pit, so as to make the anti-collapse protection effect better.

[0039] The lifting assembly includes a moving frame 501 fixedly connected to the side wall of the moving column 303. A third connecting plate 502 is fixedly connected to the side wall of the moving frame 501. A second T-shaped guide rod 507 is inserted into the top of the third connecting plate 502, and the lower end of the second T-shaped guide rod 507 is fixed to the top of the first moving plate 14. A fourth spring 506 is sleeved on the side wall of each second T-shaped guide rod 507. Two symmetrically arranged support blocks 503 are fixedly connected to the top of the first moving plate 14. The opposite side walls of the two support blocks 503 are rotatably connected to a pedal 505 through a second rotating shaft 504. The pedal 505 can be stepped on to rotate downward along the second rotating shaft 504. At the same time, it can abut against the bottom of the third connecting plate 502, so as to push the third connecting plate 502 to move upward along the second T-shaped guide rod 507. At the same time, the fourth spring 506 is compressed. When the pedal 505 is released, the third connecting plate 502 can move downward and reset under the action of the fourth spring 506. At the same time, it pushes the pedal 505 to rotate upward and reset. In this way, the third connecting plate 502 can move up and down reciprocally. When the third connecting plate 502 moves, it can drive a plurality of moving columns 303 to move up and down reciprocally along the insertion pipes 17 through the moving frame 501.

[0040] The second telescopic mechanism includes two symmetrically arranged third sleeve rods 701 fixedly connected to the bottom of the bearing plate 18. A third sleeve 702 is sleeved on the side wall of each third sleeve rod 701. The lower end of the third sleeve 702 is fixed to the top of the extrusion plate 15. A third spring 703 is sleeved on the side wall of each third sleeve 702, which plays a role in guiding and resetting the movement of the bearing plate 18.

[0041] The rotating mechanism includes two symmetrically arranged fixing blocks 1001 fixedly connected to the side wall of the bearing plate 18. The side walls of the fixing blocks 1001 are rotatably connected to rotating blocks 1003 through the third rotating shafts 1002. The rotating blocks 1003 are fixed to the side wall of the slope plate 19. Two symmetrically arranged L-shaped plates 1004 are fixedly connected to the side wall of the pressing plate 15. When the bearing plate 18 moves downward, it can abut against the bottom of the slope plate 19, thereby pushing the slope plate 19 to rotate upward along the third rotating shaft 1002, so as to rotate the slope plate 19 to the upward position, which can remind the staff.

[0042] The moving mechanism includes a U-shaped frame 601 fixedly connected to the side wall of the support plate 11. A fourth sleeve rod 603 is fixedly connected to the side wall of the U-shaped frame 601. A fourth sleeve 602 is sleeved on the side wall of the fourth sleeve rod 603. The other end of the fourth sleeve 602 is fixed to the side wall of the second moving plate 402. A threaded pipe 604 is fixedly connected to the side wall of the second moving plate 402. A threaded rod 605 is threadedly connected to the threaded pipe 604. The end of the threaded rod 605 away from the second moving plate 402 is rotatably connected to the side wall of the U-shaped frame 601. The end of the threaded rod 605 away from the second moving plate 402 is fixedly connected with an internal hexagonal head 606. By using tools such as an external air gun to rotate the internal hexagonal head 606, the rotation of the internal hexagonal head 606 drives the rotation of the threaded rod 605, so as to drive the second moving plate 402 to slide in the liquid storage cavity 401.

[0043] Working principle: When in use, during support, the bottom plate 1 is fixed to the bottom of the foundation pit through the insertion rod 12, and the support plate 11 is supported by the inclined support 13, so that the support plate 11 abuts against the slope of the foundation pit. At the same time, the pressing plate 15 can adaptively rotate and adjust to contact the soil around the foundation pit. Then, the moving mechanism drives the second movement 402 to move away from the U-shaped frame 601, so as to squeeze the hydraulic oil in the liquid storage cavity 401, so that the hydraulic oil can enter the L-shaped pipe 403. Under the action of hydraulic pressure, the moving rod 404 can be pushed to move downward. When the moving rod 404 moves downward, the U-shaped plate 16 can be driven to move downward through the second connecting block 405. At the same time, the first moving plate 14 is driven to move downward through the pressure detection mechanism, and the pressing plate 15 is driven to move downward synchronously through the second telescopic mechanism. When the pressing plate 15 abuts against the soil around the foundation pit, the surface soil can be compacted. At the same time, the second spring 203 is gradually compressed. When the U-shaped plate 16 continues to move downward, the first moving plate 14 can be driven to continue to move downward through the pressure detection mechanism, and the insertion pipe 17 and the moving column 303 are driven to move downward synchronously. When the pointed cone 1701 abuts against the soil, the insertion pipe 17 can be gradually inserted into the soil, so as to reinforce the soil around the foundation pit and improve the anti-collapse support effect.

[0044] Meanwhile, when the insertion tube 17 is gradually inserted into the soil, the first spring 806 is gradually compressed. At this time, the distance between the U-shaped plate 16 and the first moving plate 14 gradually becomes smaller. At the same time, the pushing pin 905 can be driven by the first connecting block 904 to slide along the chute 903, thereby pushing the pointer 801 to rotate downward along the first rotating shaft 902. At this time, by observing the scale plate 803 indicated by the pointer 801, the extrusion force received by the first spring 806 can be determined, and then the compactness of the soil around the foundation pit can be detected. When the indicated scale is small, it means that the compactness of the soil around the foundation pit is insufficient. At this time, the insertion tube 17 can be pulled out through the lifting mechanism. At the same time, then, after driving the pressing plate 15 to move upward, soil can be continuously filled under the pressing plate 15 and enter the insertion hole. After the soil filling is completed, the pressing plate 15 and the insertion tube 17 are driven to move downward, and so on, to ensure that the compactness of the soil around the foundation pit is higher, thereby improving the anti-collapse effect.

[0045] After the insertion tube 17 is completely inserted into the soil, at this time, the foundation pit can be protected. At the same time, the bottom of the slope plate 19 contacts the soil. And during the support process, when the load on the bearing plate 18 is heavy, the bearing plate 18 can be pushed to move in the direction close to the pressing plate 15. At the same time, the third sleeve rod 701 moves downward along the third sleeve 702, and the third spring 703 is compressed. When the bearing plate 18 moves downward, it can abut against the bottom of the slope plate 19, thereby pushing the slope plate 19 to rotate upward along the third rotating shaft 1002, so as to rotate the slope plate 19 to the upward position, which can remind the staff to avoid excessive load around the foundation pit and make the anti-collapse effect better.

[0046] In rainy weather, when the water content in the soil around the foundation pit is relatively high, the pedal 505 can be stepped on, causing it to rotate downward along the second rotating shaft 504. At the same time, it can abut against the bottom of the third connecting plate 502, thereby pushing the third connecting plate 502 to move upward along the second T-shaped guide rod 507. At the same time, the fourth spring 506 is compressed. When the pedal 505 is released, the third connecting plate 502 can move downward and reset under the action of the fourth spring 506. At the same time, it pushes the pedal 505 to rotate upward and reset. In this way, the third connecting plate 502 can move up and down reciprocally. When the third connecting plate 502 moves, it can drive a plurality of moving columns 303 to move up and down reciprocally along the insertion pipe 17 through the moving frame 501. When the moving column 303 moves upward, a negative pressure can be generated inside the insertion pipe 17. At the same time, the first one-way valve opens and the second one-way valve closes. At this time, the water in the soil around the foundation pit can enter the insertion pipe 17 through the water pumping holes 301. When the moving column 303 moves downward, the water inside the insertion pipe 17 can be squeezed. At the same time, the first one-way valve closes and the second one-way valve opens, so that the water inside the insertion pipe 17 can be squeezed and enter the hose 304 through the water outlet pipe 302, and then enter the water collecting pipe 306 and be discharged through the drain pipe 307, thus facilitating the discharge of the accumulated water in the soil around the foundation pit and making the anti-collapse protection effect better.
