[0027] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] Example 1

[0030] See also Figures 1-10 The present invention provides a technical solution: a soil seepage early warning device for geotechnical engineering, comprising a landslide 1, the landslide 1 comprising a landslide surface layer 101, a shallow layer 102 and a weathered mudstone sandstone interlayer 103, the top surface of the landslide surface layer 101 being provided with a diversion ditch 2, the top surface of the landslide surface layer 101 being provided with a drainage ditch 3, the top surface of the landslide surface layer 101 being provided with a drop chute 4 adapted to the drainage ditch 3, a detection component being provided inside the landslide 1, the detection component comprising a drainage pipe 7 and an alarm mechanism arranged inside the shallow layer 102 and the weathered mudstone sandstone interlayer 103, the outer wall of the drainage pipe 7 being wrapped with a needle-punched non-woven geotextile 9, the inner end of the drainage pipe 7 being provided with a wooden plug 10 adapted to the needle-punched non-woven geotextile 9, and the outer wall of the drainage pipe 7 being provided with a water inlet hole 11.

[0031] When in use, first clean and level the anti-slip pile 6 construction platform, use rotary drilling and other processes to construct the anti-slip pile 6, then excavate the slope, first excavate the top of the slope and then the foot of the slope, first excavate the top of the slope for unloading, which is beneficial to the stability of the landslide 1, then excavate the soil in front of the anti-slip pile 6 in stages, and at the same time carry out the shallow 102 drainage system (drainage holes in the highly permeable layer) for construction, lay out the line and position - put the drill in place - drill - empty - place the prepared drainage pipe 7 - make an inverted filter bag 8 near the panel, the drainage pipe 7 passes through the inverted filter bag 8 and is connected to the drainage hole of the concrete panel 5, set an ultra-long deep drainage hole drainage system in the weathered mudstone and sandstone interlayer 103, lay out the line and position - put the drill in place - drill - empty - place the prepared drainage pipe 7, improve the drainage system of the landslide surface 101, and repair Build surface drainage ditches 3, intercepting ditches 2 and drop chutes 4. When it rains, rainwater falling on the landslide surface 101 can be collected and discharged through the intercepting ditches 2, drainage ditches 3 and drop chutes 4. In heavy rainfall, the surface drainage system cannot drain water out of the landslide range in time. A large amount of precipitation may seep from the surface into the slope soil. Since the landslide 1 soil has a high content of debris, some of it floats in the clay soil, and some of the blocks are connected to each other. The blocks overlap to form a water channel with good permeability. Valley water and precipitation can easily seep along the highly permeable debris layer, saturating and softening the soil, reducing soil strength, and increasing deadweight and permeability. Therefore, the process of adding a drainage pipe 7 to the gravel-containing soil slope is as follows.

[0032] When laying the shallow 102 drainage system, the length of the drainage pipe 7 is set to 10-15.0m and is evenly arranged on the slope. The hole body and the buried port are wrapped with non-woven geotextile. The hole mouth protrudes about 50mm from the slope. The outward slope of the drainage hole is 5°. The drainage pipe 7 is made of a hard PVC plastic pipe with a diameter of 150mm. The drainage pipe 7 is connected by a socket. The water inlet holes 11 are evenly arranged around the entire length of the pipe. The drainage pipe 7 is wrapped with 2 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. It is blocked with a wooden plug 10 from the inner end and wrapped with the needle-punched non-woven geotextile 9.

[0033] When laying the weathered mudstone and sandstone interlayer 103 drainage system, it is mainly used to discharge the water content in the weathered mudstone and sandstone interlayer 103 stratum for a long time, minimize the water content in the soil, prevent the soil in the sliding zone from being soaked for a long time, thereby reducing the strength and causing creep. Therefore, the length of the drainage pipe 7 is set to 25.0m and is evenly arranged on the slope. The drainage pipe 7 and the buried port are wrapped with a needle-punched non-woven geotextile 9. The drainage pipe 7 extends out of the slope by about 500mm, and the outward slope of the drainage hole is 5°. The drainage pipe 7 is made of a hard PVC plastic pipe with a diameter of 75mm. The drainage pipe 7 is connected by a socket, and the water filter holes are evenly arranged along 2 / 3 of the pipe circumference. The drainage pipe 7 is wrapped with 2 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 inner end is blocked with a wooden plug 10 and wrapped with the needle-punched non-woven geotextile 9.

[0034] The moisture content inside the shallow layer 102 and the weathered mudstone-sandstone interlayer 103 is filtered by the needle-punched non-woven geotextile 9, which intercepts the silt and allows only water to pass through the water inlet hole 11 into the inside of the drain pipe 7, and then discharged to the outside of the landslide 1. When the moisture content inside the landslide 1 exceeds the standard, the amount of moisture entering the drain pipe 7 increases, so that the water entering the drain pipe 7 is more than the water discharged from the drain pipe 7. The drain pipe 7 is set as an inclined position, so that the water level inside the drain pipe 7 is increased. When the water level inside the drain pipe 7 rises to a certain height, it will drive the alarm mechanism to work and sound an alarm. At the same time, the alarm mechanism can accelerate the discharge of water inside the drain pipe 7.

[0035] See also Figure 1 and Figure 3 The surface of the landslide 1 is provided with a concrete panel 5, and the outer wall of the concrete panel 5 is provided with anti-slide piles 6. A filter bag 8 adapted to the drain pipe 7 is provided on one side of the landslide 1 close to the concrete panel 5.

[0036] When in use, the concrete panel 5 can effectively cover and protect the surface of the landslide 1. It has the characteristics of waterproof, anti-corrosion, pressure resistance and durability, preventing the landslide 1 from collapsing. The anti-slip piles 6 are deeply embedded in the stable stratum below the sliding surface of the landslide 1. The anchoring force and passive resistance provided by the stratum are used to transfer the thrust of the landslide 1 to the stable area, forming a mechanical balance to prevent the landslide 1 from moving further. The anti-filtration bag 8 can prevent the particles inside the landslide 1 from being carried away by the infiltrating water flow, and only allows the water flow to pass smoothly and be discharged, reducing the internal water pressure, avoiding the landslide 1 from causing pipe bursts, soil flow and other infiltration deformations due to soil loss, and ensuring the structural integrity of the landslide 1.

[0037] See also Figure 1 and Figure 2 The intercepting ditch 2 should be laid out in accordance with the terrain, 5m away from the rear 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 toward the landslide 1 from the upper slope direction of the landslide 1, protecting the foot of the landslide 1 from water scouring. At the same time, the intercepting ditch 2 is not less than 0.3%, which can ensure drainage efficiency and prevent water scouring.

[0039] See also Figure 9 An ecological bag 24 is provided on the surface of the landslide surface layer 101 and fixed by anchor nails.

[0040] When in use, by arranging the ecological bag 24 on the landslide surface 101, vegetation can be formed on the landslide surface 101, thereby preventing soil erosion and precipitation infiltration on the landslide surface 101.

[0041] See also Figure 3-Figure 8 The alarm mechanism includes a fixing ring 12 arranged on the inner wall of one 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 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 connecting pipe 15, and the protective box 16 is fixed to the inner wall of the drain pipe 7 through multiple groups of connecting columns, a connecting shaft 18 is rotatably connected to the inner wall of the connecting pipe 15, a spiral blade 19 adapted to the connecting pipe 15 is provided on the outer wall of the connecting shaft 18, a water outlet 20 is opened at the bottom end of the connecting pipe 15 on the side close to 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 flashlight 22 and an alarm 23 are installed on the outer wall of the protective box 16, and the flashlight 22 and the alarm 23 are electrically connected to the micro-generator 21.

[0042] When in use, when the water inside the landslide 1 enters the inside of the drain pipe 7, the water can flow along the inner wall of the drain pipe 7 toward the outside of the landslide 1. At this time, the water will pass through the notch 13 at the bottom of the fixing ring 12 and be discharged from the outlet of the drain pipe 7. When encountering heavy rain weather, the water content inside the landslide 1 increases, causing a large amount of water to enter the inside of the drain pipe 7. At this time, due to the small size of the notch 13, the water passing through the notch 13 is much smaller than the water entering the inside of the drain pipe 7. The drain pipe 7 is set to be inclined, so that the water will accumulate on the surface of the fixing ring 12 in the drain pipe 7, and the water level will gradually rise with the passage of time. When the water level accumulated in the drain pipe 7 rises to a certain height, it will enter the inside of the funnel 14. At this time, the accumulated water will enter the inside of the connecting pipe 15 through the funnel 14 and impact the surface of the spiral blade 19. The spiral blade 1 When impacted, the connecting shaft 18 is driven to rotate. At this time, the rotation of the connecting shaft 18 provides power to the micro-generator 21, which drives the micro-generator 21 to generate electricity. At this time, the micro-generator 21 is electrically connected to the flashlight 22 and the alarm 23, so that the alarm 23 sounds an alarm to remind the staff that the water content inside the landslide 1 is high. At the same time, the flashlight 22 emits a warning light to assist the staff in determining the location of the high water content. At the same time, the rotation of the spiral blades 19 can accelerate the flow rate of water inside the connecting pipe 15, so that the accumulated water quickly passes through the connecting pipe 15 and is discharged through the water outlet 20. The protective box 16 can protect the micro-generator 21 to prevent the seepage water from wetting the micro-generator 21 when it is discharged through the drain pipe 7, thereby causing the micro-generator 21 to malfunction and affect its normal operation.

[0043] See also Figure 8 Two groups of spiral blades 19 are staggeredly arranged on the outer wall of the connecting shaft 18.

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

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

[0046] When in use, when the accumulated water enters the funnel 14, it will flow along the surface of the spiral channel 17, thereby rotating to generate a vortex. The water flow converts part of its energy into angular momentum through the vortex motion, making the water flow more concentrated (reducing radial diffusion), so that the energy is more concentrated when hitting the target, which can increase the force of the accumulated water hitting the surface of the spiral blade 19 and increase the speed of the spiral blade 19 rotating after being impacted.

[0047] See also Figure 6 、 Figure 8 and Figure 10The alarm mechanism also includes a mounting ring 25 mounted 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, and a plurality of transmission blocks 27 are evenly spaced and staggered on the outer wall of the transmission rod 26. A connecting plate 28 is fixedly connected to the outer wall of one side of the mounting ring 25, and a connecting ring 29 is fixedly connected to the outer wall of one end 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, and a connecting pipe 31 adapted to the through hole 30 is provided on the outer wall of one side of the connecting ring 29. A push rod 32 is slidably connected to the inner wall of the tube 31, and a piston 33 adapted to the connecting tube 31 is provided on the outer wall of one end of the push rod 32, and a return spring 34 adapted to the piston 33 is provided on the inner wall of the connecting tube 31. A water outlet 35 is provided on the outer wall of one side of the connecting tube 31, and a limit block 36 adapted to the water outlet 35 is provided on the inner wall of the connecting tube 31. A spring sheet 37 adapted to the limit block 36 is provided on the outer wall of the connecting tube 31, and a slot 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 the multiple 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 opposite to 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 connecting pipe 31 and squeeze the return spring 34, so that the push rod 32 pushes the piston 33 to slide inside the connecting pipe 31. The piston When sliding, 33 will push the limit block 36 to rotate and squeeze the spring sheet 37, so that the limit block 36 and the water outlet 35 are closed. At this time, the piston 33 continues to slide inside the connecting pipe 31 and squeezes the internal air and moisture of the connecting pipe 31, so that the air and moisture are blown to the surface of the needle-punched non-woven geotextile 9 through the through hole 30 and the water inlet hole 11. In this process, the sludge adhering to the inside of the filter screen holes of the needle-punched non-woven geotextile 9 can be blown out. When the push rod 32 is separated from the limit block 36, the reset spring 34 will push the push rod 32 to reset the piston 33 to generate a suction force through the connecting pipe 31, and suck the accumulated water inside the landslide 1 into the inside of the connecting pipe 31, and enter the drain pipe 7 through the water outlet 35.

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

[0050] When rainwater falls on the landslide surface 101, the intercepting ditch 2 can intercept the surface water flowing toward the landslide 1 from the upper slope, protecting the slope foot from erosion. The drainage ditch 3 is used to drain the surface water gathered in the slope range of the landslide 1. The drop chute 4 is used to connect the drainage ditches 3 between different platforms for drainage in the slope direction of the landslide 1. The ecological bag 24 can form vegetation on the landslide surface 101 to prevent soil erosion and precipitation infiltration in the landslide surface 101.

[0051] During heavy rainfall, the water content in the shallow layer 102 and the weathered mudstone-sandstone interlayer 103 increases sharply. At this time, the seepage water is filtered through the needle-punched non-woven geotextile 9 and enters the inside of the drain pipe 7, and is then 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 inside of the drain pipe 7. At this time, due to the small size of the notch 13, the water passing through the notch 13 is much smaller than the water entering the inside of the drain pipe 7. The drain pipe 7 is set as an inclined position, so that the water will accumulate on the surface of the fixed ring 12 in the drain pipe 7, and the water level will gradually rise with the passage of time. When the water level accumulated in the drain pipe 7 rises to a certain height, it will enter the inside of the funnel 14. At this time, the accumulated water will pass through the funnel 1 4 enters the interior of the connecting pipe 15 and 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 drives the micro-generator 21 to generate electricity. At this time, the micro-generator 21 is electrically connected to the flashlight 22 and the alarm 23, so that the alarm 23 sounds an alarm to remind 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 locate the location of the high water content. At the same time, the rotation of the spiral blade 19 can accelerate the flow rate of water inside the connecting pipe 15, so that the accumulated water quickly passes through the connecting pipe 15 and is discharged through the water outlet 20.
