Description

Technical Field

[0001] This utility model relates to the technical field of geotechnical engineering, specifically to a seepage-proof structure. Background Technology

[0002] Geotechnical engineering is a field of study that addresses problems in rock and soil engineering, including foundations, slopes, and underground engineering. When faced with rainy weather and extreme conditions, water can seep into the interior of geotechnical structures, potentially affecting their strength and service life.

[0003] A seepage-proof structure for geotechnical engineering, disclosed in publication number CN218148418U, includes a geotechnical slope, a concrete reinforcement layer, and a waterproof layer. The upper layer of the geotechnical slope is provided with a concrete reinforcement layer, and fasteners are inserted through the interior of the concrete reinforcement layer. A waterproof layer is laid on top of the concrete reinforcement layer, and a baffle is provided at the lower edge of the slope of the geotechnical slope.

[0004] The aforementioned document describes how the filling layer within the grating plate buffers and protects the waterproof layer, ensuring efficient protection of the slope of the geotechnical engineering project through a seepage-proof structure. The grating plate and filling layer at the bottom of the crushed stone layer can store water in the shallow layer of the geotechnical engineering slope, ensuring the normal growth of vegetation in the vegetation layer and preventing soil erosion on the sloping slope. The filter cover filters the water flow from the water pipe port and the diversion channel, ensuring that mud and other debris in the rainwater are filtered out by the filter cover, preventing excessive mud and debris from flowing into the drainage ditch.

[0005] However, since drainage ditches drain water continuously and contain a lot of impurities, even though the aforementioned document has a filtration structure, some impurities will still accumulate at the bottom of the drainage ditch, affecting the drainage effect. Furthermore, the drainage ditches in the aforementioned document are prone to accumulating leaves and weeds, leading to blockages in the drainage pipes inside the drainage ditches. Therefore, we propose a seepage-proof structure to solve the problems mentioned above. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4This utility model provides a technical solution: a seepage-proof structure, including a soil slope 1, a drainage ditch 2, and a drainage channel 12. The drainage ditch 2 is installed at the bottom of the soil slope 1. A groove 19 is provided above the drainage ditch 2 at the bottom of a supporting wall 3. An adjusting screw 20 protruding from the surface of the drainage ditch 2 is rotatably connected inside the groove 19, facilitating the rotation of the adjusting screw 20 within the supporting wall 3. The adjusting screw 20 is threadedly connected to a scraper 21 whose upper end is engaged and slidably connected to the groove 19. The bottom surface of the scraper 21 is in contact with the inner surface of the drainage ditch 2. The surface of the scraper 21 is perforated, allowing the adjusting screw 20 to drive the scraper 21 to move threadedly, thus scraping away dirt at the bottom of the drainage ditch 2 and improving the drainage effect of the device. A supporting wall 12 is installed above the drainage ditch 2. Wall 3, the surface of the supporting wall 3 is evenly provided with drainage holes 18, and the drainage holes 18 are set at an angle, so that the water flowing down the soil layer 10 can be discharged into the drainage ditch 2 through the drainage holes 18. A base plate 4 is poured on the slope of the rock and soil slope 1, and a first filter screen 5 is set on the top of the base plate 4. A drainage cavity 6 is set between the first filter screen 5 and the base plate 4, and a first support block 7 is evenly fixed below the first filter screen 5. Soil-retaining gauze 8 is laid on the outer surface of the first filter screen 5, and a stone filling area 9 is set on the outer side of the soil-retaining gauze 8. Threaded holes 22 are opened at the four corners of the base plate 4. The first filter screen 5 and the soil-retaining gauze 8 are connected to the base plate 4 by mounting bolts 23 and fastening nuts 24, which can improve the tightness of the connection between the base plate 4 and the first filter screen 5 and the soil-retaining gauze 8, and improve the water-proof effect of the device.

[0024] A soil layer 10 is provided on the outer side of the stone filling area 9, and a plant planting frame 11 is installed on the outer surface of the soil layer 10. A drainage ditch 12 is provided on the upper surface of the rock and soil slope 1, and a second filter screen 13 is provided inside the drainage ditch 12. The second filter screen 13 is concave and is detachably connected to the drainage ditch 12 above the rock and soil slope 1, which facilitates the filtration of water inside the drainage ditch 12 through the second filter screen 13, and also facilitates the removal of the second filter screen 13. A second support block 14 is evenly fixed below the net 13, and a support plate 15 is evenly fixed above the interior of the second filter net 13. A dirt-blocking mesh plate 16 is provided above the second filter net 13. A drain pipe 17 is provided between the drainage ditch 12 and the drainage channel 2. The dirt-blocking mesh plate 16 and the drainage ditch 12 above the rock and soil slope 1 form a snap-fit ​​connection. The upper surface of the dirt-blocking mesh plate 16 is flush with the upper surface of the rock and soil slope 1, which can effectively block leaves and weeds and prevent the drainage pipe 17 from becoming blocked.

[0025] Working principle: First, when it rains, rainwater seeps into the soil layer 10 and into the soil-separating gauze 8 and the first filter screen 5, entering the drainage chamber 6 between the bottom plate 4 and the filter screen 5. The water seeps in and is then discharged into the drainage ditch 2 through the drainage chamber 6. Water flowing directly down the soil layer 10 passes through the drainage holes 18 on the surface of the supporting wall 3 and is discharged into the drainage ditch 2. Water inside the drainage ditch 12 at the top of the rock and soil slope 1 is discharged into the drainage ditch 2 through the drainage pipe 17 at its bottom. This ensures the drainage of the device and prevents water seepage due to untimely drainage.

[0026] The top of the drainage ditch 12 is equipped with a dirt-blocking mesh plate 16, which can effectively block large leaves, weeds and other impurities. In conjunction with the use of the second filter screen 13 inside, it can effectively prevent the drainage pipe 17 from becoming blocked. An adjusting screw 20 is installed above the drainage ditch 2. By rotating the adjusting screw 20, it can drive the scraper 21 to move threadedly on the sliding groove 19 at the bottom of the supporting wall 3, so that the scraper 21 can scrape the bottom of the drainage ditch 2, preventing impurities from settling and adhering to the drainage ditch 2, making it difficult to drain water and affecting the subsequent drainage effect. This is the working principle of this waterproof structure.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
