Description

Technical Field

[0001] This invention relates to the field of geotechnical engineering technology, and in particular to a soil seepage early warning device for geotechnical engineering. Background Technology

[0002] With the continuous development of the national economy and the large-scale development of engineering projects, a large number of slope projects have emerged in the construction process. Under the influence of special climate and environment such as heavy rainfall, these slopes are prone to geological disasters such as landslides and collapses, which pose a threat to people's lives and safety and cause serious losses. In order to prevent the occurrence of such geological disasters, it is necessary to manage slopes.

[0003] Chinese Patent CN118858099B, published on March 7, 2025, discloses a soil seepage early warning device for geotechnical engineering. It can adapt to monitoring at different depths and meet different work needs.

However, this soil seepage early warning device for geotechnical engineering can only provide early warning of seepage, and its function is relatively simple. After the alarm is triggered, it can drain the water inside the soil. If the soil is not reinforced in time, it is easy to cause collapse, which makes it still inconvenient to use.

[0007] Furthermore, the intercepting ditch is laid out in accordance with the terrain, at least 5m away from the rear edge of the slope crest, and the longitudinal slope of the ditch bottom should be no less than 0.3%.

[0008] Furthermore, the drainage ditches are installed on each excavation platform, and the drainage ditches are concave in shape.

[0009] Furthermore, the surface of the landslide layer is covered with eco-bags and secured with anchors.

[0010] Furthermore, the top half of the end of the drainage pipe near the concrete panel is perforated, while the bottom half is not perforated. The top two-thirds of the end of the drainage pipe that extends into the landslide is perforated, while the bottom one-third is not perforated.

[0011] Furthermore, the alarm mechanism includes a fixing ring disposed on the inner wall of the end of the drain pipe extending out of the landslide. A notch is provided on the outer wall of the bottom end of the fixing ring. A funnel is fixedly connected to the inner wall of the fixing ring.

A flashlight and an alarm are installed on the outer wall of the protective box, and the flashlight and alarm are electrically connected to the miniature generator.

[0012] Furthermore, the spiral blades are arranged in two sets at different angles on the outer wall of the connecting shaft.

[0013] Furthermore, a spiral channel is provided on the inner wall of the funnel.

[0014] Furthermore, the alarm mechanism also includes a mounting ring installed on the inner wall of the drain pipe. A transmission rod is rotatably connected to the inner wall of the mounting ring.

[0015] Unlike existing technologies, the beneficial effects of this application are as follows: This soil seepage early warning device for geotechnical engineering drains water from the landslide surface through the combination of intercepting ditches, drainage ditches, and drop troughs. Water seeping down due to heavy rainfall or groundwater contained in the slope itself can be quickly collected and discharged through the drainage pipe, which can effectively reduce the amount of water seeping into the ground surface, thereby maintaining the strength and self-weight of the underlying soil and reducing seepage force. When the water content inside the slope reaches a dangerous value, the water level inside the drainage pipe increases and drives the alarm mechanism to work and issue an alarm. At the same time, the alarm mechanism can accelerate the discharge of water accumulated inside the drainage pipe. Attached Figure Description

[0027] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] Example 1

[0030] Please see Figures 1-10 This invention provides a technical solution: a soil seepage early warning device for geotechnical engineering, including a landslide 1. The landslide 1 includes a landslide surface layer 101, a shallow layer 102, and weathered mudstone and sandstone interbedded layers 103. A water interception ditch 2 is provided on the top surface of the landslide surface layer 101, a drainage ditch 3 is provided on the top surface of the landslide surface layer 101, and a drop trough 4 adapted to the drainage ditch 3 is provided on the top surface of the landslide surface layer 101. Detection components are provided inside the landslide 1. The detection components include a drain pipe 7 and an alarm mechanism installed inside the shallow layer 102 and the weathered mudstone and sandstone interbedded layers 103. The outer wall of the drain pipe 7 is wrapped with needle-punched non-woven geotextile 9, and a wooden plug 10 adapted to the needle-punched non-woven geotextile 9 is provided at the inner end of the drain pipe 7. A water inlet hole 11 is opened on the outer wall of the drain pipe 7.

[0031] During use, first, the construction platform for the anti-slide piles 6 is cleaned and leveled. The anti-slide piles 6 are then constructed using rotary drilling and other techniques. Next, the slope is excavated, first at the top and then at the toe. Excavating the top first allows for unloading, which is beneficial for the stability of the landslide 1. Then, the soil in front of the anti-slide piles 6 is excavated in stages. Simultaneously, the shallow drainage system 102 (drainage holes in a highly permeable layer) is constructed. The process involves: layout and positioning, drilling rig placement, drilling, clearing, placing the fabricated drainage pipe 7, and installing a filter bag 8 near the panel. The drainage pipe 7 passes through the filter bag 8 and connects to the drainage holes in the concrete panel 5. An ultra-long, deep drainage system is installed in the weathered mudstone and sandstone interbedded layer 103. The process involves: layout and positioning, drilling rig placement, drilling, clearing, placing the fabricated drainage pipe 7, and completing the surface drainage system 101 of the landslide. Constructing surface drainage ditch 3, intercepting ditch 2, and drop trough 4 allows rainwater to be collected and discharged when it falls on the landslide surface 101 during rainfall. However, during heavy rainfall, the surface drainage system may not be able to drain water away from the landslide area in time, and a large amount of precipitation may seep into the slope soil. Due to the high content of gravel in the soil of landslide 1, some of the gravel floats in the cohesive soil, while some gravel is connected to each other, forming water channels with good permeability. Valley water and precipitation can easily seep down along the permeable gravel layer, saturating and softening the soil, reducing soil strength, increasing self-weight and permeability. Therefore, the following process is required when adding drainage pipe 7 to the gravel-containing slope.

[0032] When laying the shallow 102 drainage system, the length of the drainage pipe 7 is set to 10-15.0m, and it is evenly distributed on the slope. The hole and the buried port are wrapped with non-woven geotextile. The hole protrudes about 50mm from the slope. The drainage hole has an outward slope of 5°. The drainage pipe 7 is made of rigid PVC plastic pipe with a diameter of 150mm. The drainage pipe 7 is connected by a socket. The water inlet hole 11 is evenly distributed along the entire length of the pipe. The drainage pipe 7 is wrapped with two layers of 300-400g / m2 needle-punched non-woven geotextile 9 and tied with iron wire. The performance indicators of the needle-punched non-woven geotextile 9 must meet the requirements of the specifications. The needle-punched non-woven geotextile 9 is plugged with a wooden plug 10 from the inner end and wrapped.

[0033] When laying the drainage system for the weathered mudstone and sandstone interbedded layer 103, the main purpose is to drain the water content in the weathered mudstone and sandstone interbedded layer 103 over a long period, minimize the water content in the soil, and prevent the soil at the slip zone from being soaked for a long time, thus reducing its strength and causing creep. Therefore, the drainage pipe 7 is 25.0m long and is evenly distributed on the slope. The entire body of the drainage pipe 7 and its buried port are wrapped with needle-punched non-woven geotextile 9. The drainage pipe 7 extends about 500mm out of the slope, and the drainage hole has an outward slope of 5°. The drainage pipe 7 is made of 75mm diameter rigid PVC. The plastic pipe is made with a sleeve connection for the drainage pipe 7. The filter holes are evenly distributed around 2 / 3 of the pipe circumference. The drainage pipe 7 is wrapped with two layers of 300-400g / m2 needle-punched non-woven geotextile 9 and tied with wire. The performance indicators of the needle-punched non-woven geotextile 9 must meet the requirements of the specifications. The needle-punched non-woven geotextile 9 is plugged and wrapped with a wooden plug 10 from the inner end.

[0034] The water content inside the shallow layer 102 and the weathered mudstone and sandstone interbedded layer 103 is filtered by the needle-punched non-woven geotextile 9, which intercepts the mud and sand, allowing only water to pass through the inlet hole 11 and enter the interior of the drainage pipe 7, thereby discharging it to the outside of the landslide 1. When the water content inside the landslide 1 exceeds the standard, the amount of water entering the drainage pipe 7 increases, making the amount of water entering the drainage pipe 7 more than the amount of water discharged from the drainage pipe 7. Because the drainage pipe 7 is inclined, the water level inside the drainage pipe 7 increases. When the water level inside the drainage pipe 7 rises to a certain height, it will activate the alarm mechanism to sound an alarm. At the same time, the alarm mechanism can accelerate the discharge of water from the drainage pipe 7.

[0035] Please see Figure 1 and Figure 3 The surface of landslide 1 is provided with a concrete panel 5, and anti-slide piles 6 are provided on the outer wall of the concrete panel 5. A drainage pipe 7 and a matching filter bag 8 are provided on the side of landslide 1 closest to the concrete panel 5.

[0036] In use, the concrete panel 5 effectively covers and protects the surface of landslide 1, possessing waterproof, corrosion-resistant, compressive-resistant, and durable characteristics, preventing landslide 1 from collapsing. The anti-slide piles 6 are driven deep into the stable stratum below the sliding surface of landslide 1, utilizing the anchoring force and passive resistance provided by the stratum to transfer the thrust of landslide 1 to the stable area, forming a mechanical balance and preventing further movement of landslide 1. The filter bag 8 prevents particles inside landslide 1 from being carried away by seepage water, allowing only smooth water flow and discharge, reducing internal water pressure, and preventing seepage deformation such as piping and soil erosion caused by soil loss, thus ensuring the structural integrity of landslide 1.

[0037] Please see Figure 1 and Figure 2 Interception ditch 2 should be laid out according to the terrain, at least 5m away from the back edge of the slope top, and the longitudinal slope of the ditch bottom should be no less than 0.3%.

[0038] When in use, it can intercept surface water flowing towards landslide 1 from the upper slope direction, protecting the toe of landslide 1 from water erosion. At the same time, the intercepting ditch 2, with a slope of not less than 0.3%, can ensure drainage efficiency and prevent water erosion.

[0039] Please see Figure 9 Ecological bags 24 are installed on the surface of the landslide surface layer 101 and fixed by anchors.

[0040] When in use, by setting up ecological bags 24 on the landslide surface 101, vegetation can be formed on the landslide surface 101 to prevent soil erosion and rainwater infiltration on the landslide surface 101.

[0041] Please see Figures 3-8 The alarm mechanism includes a fixing ring 12 installed on the inner wall of the end of the drain pipe 7 extending out of the landslide 1. A notch 13 is opened on the outer wall of the bottom end of the fixing ring 12. A funnel 14 is fixedly connected to the inner wall of the fixing ring 12. A first connecting pipe 15 is fixedly connected to the outer wall of one end of the funnel 14. A protective box 16 is fixedly connected to the outer wall of one end of the first connecting pipe 15. The protective box 16 is fixed to the inner wall of the drain pipe 7 by multiple sets of connecting columns. A connecting shaft 18 is rotatably connected to the inner wall of the first connecting pipe 15. A spiral blade 19 adapted to the first connecting pipe 15 is provided on the outer wall of the connecting shaft 18. A first water outlet 20 is opened at the bottom end of the first connecting pipe 15 near the protective box 16. A micro generator 21 adapted to the connecting shaft 18 is provided on the inner wall of the protective box 16. A flashing light 22 and an alarm 23 are installed on the outer wall of the protective box 16. The flashing light 22 and the alarm 23 are electrically connected to the micro generator 21.

[0042] In use, when water from inside the landslide 1 enters the drain pipe 7, the water flows along the inner wall of the drain pipe 7 towards the outside of the landslide 1. At this time, the water passes through the notch 13 at the bottom of the fixing ring 12 and is discharged from the outlet of the drain pipe 7. During heavy rainfall, the water content inside the landslide 1 increases, causing a large amount of water to enter the drain pipe 7. At this time, because the size of the notch 13 is small, the amount of water passing through the notch 13 is much smaller than the amount of water entering the drain pipe 7. Because the drain pipe 7 is inclined, the water will accumulate on the surface of the fixing ring 12 inside the drain pipe 7, and the water level will gradually rise over time. When the water level in the drain pipe 7 rises to a certain height, it will enter the funnel 14. At this time, the accumulated water will enter the first connecting pipe 15 through the funnel 14 and impact the surface of the spiral blade 19. The spiral blade 19 is subjected to... Upon impact, the connecting shaft 18 rotates, providing power to the micro generator 21. This power drives the micro generator 21 to generate electricity. The micro generator 21 is electrically connected to the flashlight 22 and the alarm 23, causing the alarm 23 to sound an alarm, alerting workers that the landslide 1 has a high water content. Simultaneously, the flashlight 22 emits a warning light to help workers locate areas with high water content. At the same time, the rotation of the spiral blades 19 accelerates the flow of water within the first connecting pipe 15, allowing the accumulated water to quickly pass through the first connecting pipe 15 and be discharged through the first outlet 20. The protective box 16 protects the micro generator 21, preventing water seepage from wetting it when it drains through the drain pipe 7, thus preventing malfunctions and disruption of normal operation.

[0043] Please see Figure 8 Two sets of spiral blades 19 are offset on the outer wall of the connecting shaft 18.

[0044] When in use, the arrangement of the double helix blades 19 can form a segmented sealed cavity, reducing liquid backflow.

[0045] Please see Figure 7 A spiral channel 17 is provided on the inner wall of the funnel 14.

[0046] When in use, the water flows along the surface of the spiral channel 17 as it enters the funnel 14, thus generating a vortex. The water flow converts some of its energy into angular momentum through the vortex motion, making the water flow more concentrated (reducing radial diffusion). This results in more concentrated energy when it hits the target, which increases the force of the water hitting the surface of the spiral blade 19 and increases the rotation speed of the spiral blade 19 after being impacted.

[0047] Please see Figure 6 , Figure 8 and Figure 10The alarm mechanism also includes a mounting ring 25 installed on the inner wall of the drain pipe 7. A transmission rod 26 is rotatably connected to the inner wall of the mounting ring 25. Multiple sets of transmission blocks 27 are distributed at equal intervals and staggered on the outer wall of the transmission rod 26. A connecting plate 28 is fixedly connected to one side of the outer wall of the mounting ring 25. A connecting ring 29 is fixedly connected to one end of the outer wall of the connecting plate 28. A through hole 30 adapted to the water inlet hole 11 is provided on the outer wall of the connecting ring 29. A second connecting pipe 31 adapted to the through hole 30 is provided on one side of the outer wall of the connecting ring 29. The inner wall of the second connecting pipe 31... A push rod 32 is slidably connected to the wall. A piston 33 adapted to a second connecting pipe 31 is provided on the outer wall of one end of the push rod 32. A return spring 34 adapted to the piston 33 is provided on the inner wall of the second connecting pipe 31. A second water outlet 35 is opened on one side of the outer wall of the second connecting pipe 31. A limiting block 36 adapted to the second water outlet 35 is provided on the inner wall of the second connecting pipe 31. A spring plate 37 adapted to the limiting block 36 is provided on the outer wall of the second connecting pipe 31. A groove 38 adapted to the transmission rod 26 is provided on the outer wall of one end of the connecting shaft 18.

[0048] When installing the drain pipe 7, first slide the mounting ring 25 into the interior of the drain pipe 7, and through the connection of the connecting plate 28, push multiple sets of connecting rings 29 into the interior of the drain pipe 7 in sequence, so that the through hole 30 on the surface of the connecting ring 29 is aligned with the water inlet hole 11. At this time, one end of the transmission rod 26 will engage with the groove 38 on the surface of the connecting shaft 18. When the connecting shaft 18 rotates, the engagement of the groove 38 drives the transmission rod 26 and the transmission block 27 to rotate synchronously. When the transmission block 27 moves to the surface of the push rod 32, the transmission block 27 will squeeze the push rod 32, thereby pushing the push rod 32 to slide into the interior of the second connecting pipe 31 and squeezing the return spring 34, so that the push rod 32 pushes the piston 33 to slide inside the second connecting pipe 31. When activated, the limiting block 36 rotates and squeezes the spring plate 37, causing the limiting block 36 to close with the second outlet 35. At this time, the piston 33 continues to slide inside the second connecting pipe 31 and squeezes the air and water inside the second connecting pipe 31, causing the air and water to be blown onto the surface of the needle-punched nonwoven geotextile 9 through the through hole 30 and the water inlet hole 11. During this process, the sludge adhering to the filter screen holes of the needle-punched nonwoven geotextile 9 can be blown out. After the push rod 32 separates from the limiting block 36, the reset spring 34 will push the push rod 32 to reset, causing the piston 33 to generate a suction force through the second connecting pipe 31, and suck the water inside the landslide 1 into the interior of the second connecting pipe 31, and enter the drain pipe 7 through the second outlet 35.

[0049] The implementation principle of this application embodiment is as follows:

[0050] When rainwater falls onto the landslide surface 101, the intercepting ditch 2 can intercept the surface water flowing towards the landslide 1 from the upper slope direction, protecting the slope toe from water erosion. The drainage ditch 3 is used to drain the surface water that accumulates within the landslide 1 slope area. The drop trough 4 is used to connect the drainage ditches 3 between different platforms for drainage in the direction of the landslide 1 slope. The ecological bag 24 can form vegetation on the landslide surface 101 to prevent soil erosion and rainwater infiltration on the landslide surface 101.

[0051] During periods of heavy rainfall, the water content within the shallow layer 102 and the weathered mudstone and sandstone interbedded layers 103 increases dramatically. At this time, seepage water, filtered through the needle-punched nonwoven geotextile 9, enters the drainage pipe 7 and is discharged to the outside of the landslide 1. When the water content inside the landslide 1 exceeds the standard, a large amount of water enters the drainage pipe 7. Because the opening 13 is small, the amount of water passing through it is much less than the amount entering the drainage pipe 7. Due to the inclined design of the drainage pipe 7, water accumulates on the surface of the fixing ring 12 inside the pipe, and the water level gradually rises over time. When the accumulated water level in the drainage pipe 7 reaches a certain height, it enters the funnel 14. At this point, the accumulated water flows through the funnel 14 into the... Inside the connecting pipe 15, water impacts the surface of the spiral blade 19. When the spiral blade 19 is impacted, it drives the connecting shaft 18 to rotate. At this time, the rotation of the connecting shaft 18 provides power to the micro generator 21, which in turn drives the micro generator 21 to work and generate electricity. At this time, the micro generator 21 is electrically connected to the flashlight 22 and the alarm 23, causing the alarm 23 to sound an alarm, reminding the staff that the water content inside the landslide 1 is high. At the same time, the flashlight 22 emits a warning light to help the staff determine the location with high water content. Meanwhile, the rotation of the spiral blade 19 can accelerate the flow speed of water inside the first connecting pipe 15, allowing the accumulated water to quickly pass through the first connecting pipe 15 and be discharged through the first outlet 20.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
