Description

Technical Field

[0001] This utility model relates to the field of slope design technology, and more specifically, to a slope seepage prevention structure for geotechnical engineering design. Background Technology

[0002] Geotechnical engineering refers to the study of rock and soil masses. When carrying out geotechnical engineering, workers need to use slopes to support the rock and soil. Slopes are generally made of soil. Because slopes are made of soil, rainwater can easily seep into the slope during rainy weather, causing the slope to collapse and posing a threat to the safety of people.

[0003] The existing method for slope seepage prevention involves installing a seepage barrier layer. However, this method results in the barrier layer bearing excessive pressure, allowing a significant amount of water to still seep in. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a slope seepage prevention structure for geotechnical engineering design that can drain some water and reduce the pressure on the seepage prevention layer.

[0005] A slope seepage prevention structure designed for geotechnical engineering includes: a concrete base layer on the slope surface; a waterproof membrane on the surface of the concrete base layer; a protective layer on the waterproof membrane; a fixing mechanism in the protective layer; a drainage mechanism on the upper part of the protective layer, the drainage mechanism being connected to the fixing mechanism, the drainage mechanism including a positioning frame and a gabion, the gabion being disposed within the positioning frame; and a protective netting laid on the upper part of the positioning frame.

[0006] Furthermore, the fixing mechanism includes a steel mesh and an embedded sleeve. The steel mesh is laid inside the protective layer, the bottom of the embedded sleeve is located below the steel mesh, and the top of the embedded sleeve penetrates the protective layer.

[0007] Furthermore, the bottom of the pre-embedded sleeve is a support plate, and the size of the support plate is larger than the hole size of the steel mesh.

[0008] Furthermore, adjacent positioning frames fit together, one side of each positioning frame is provided with a connector, and the other side of each positioning frame is provided with a slot, the connector being able to be inserted into the slot.

[0009] Furthermore, the connector and the connector slot are provided with a connection hole, which is located above the pre-embedded sleeve.

[0010] Furthermore, the hydrophobic mechanism also includes a fixing bolt, the bottom of which is a screw and the top of which is a crossbar. The screw passes through the connection hole of the connector and the connector slot, and the bottom of the screw is screwed to the pre-embedded sleeve.

[0011] Furthermore, the length of the crossbar is greater than the length of the two positioning frames, and the end of the crossbar is located above the gabion.

[0012] Furthermore, water channels are provided at the upper and lower parts of the positioning frame, and the water channels between adjacent positioning frames are connected.

[0013] Furthermore, the upper and lower gabions are connected by tie hooks, which hold the gabion frame and are located above the water passage.

[0014] Furthermore, a connecting post is provided at the top of the positioning frame, and the protective net is wrapped around the connecting post.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] ① This structure utilizes the hydrophobicity of the gabions to drain water downwards. At the same time, some of the water that seeps in passes through the protective layer and waterproof membrane, keeping most of the water outside the waterproof membrane. This keeps the interior of the geotechnical slope dry and ensures the stability of the geotechnical slope. Attached Figure Description

[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] like Figure 1 , Figure 2 As shown, a slope seepage prevention structure designed for geotechnical engineering includes: a concrete base layer 1 on the slope surface; a waterproof membrane 2 on the surface of the concrete base layer 1; a protective layer 3 on the waterproof membrane 2; a fixing mechanism 4 in the protective layer 3; a drainage mechanism 5 on the upper part of the protective layer 3, the drainage mechanism 5 being connected to the fixing mechanism 4, the drainage mechanism 5 including a positioning frame 51 and a gabion 52, the gabion 52 being disposed inside the positioning frame 51; and a protective net 6 laid on the upper part of the positioning frame 51.

[0024] When designing slopes in geotechnical engineering, a concrete base layer 1 is first laid on the surface of the concrete slope using a shotcrete method. A waterproof membrane 2 is then laid on top of the concrete base layer 1. The waterproof membrane 2 has a seepage-proof function, intercepting most of the water that continues to seep into the slope, thus ensuring the slope's safety. A protective layer 3, made of impermeable concrete, is placed on the surface of the waterproof membrane 2. The protective layer 3 protects the surface of the waterproof membrane 2 from scratches, ensuring that the waterproof membrane 2's seepage-proof capability reaches its service life.

[0025] The fixing mechanism 4, located within the protective layer 3, enhances its strength. The fixing mechanism 4 includes a reinforcing mesh 41 and an embedded sleeve 42. The reinforcing mesh 41 is laid within the protective layer 3, the bottom of the embedded sleeve 42 is below the reinforcing mesh 41, and the top of the embedded sleeve 42 penetrates the protective layer 3. Before pouring the protective layer 3, the position of the embedded sleeve 42 is determined by marking lines on the waterproof membrane 2. Then, the reinforcing mesh 41 is laid, and the concrete for the protective layer 3 is poured. After the concrete solidifies, the reinforcing mesh 41 provides tensile strength to the protective layer 3, making it less prone to cracking.

[0026] like Figure 3 As shown, the bottom of the embedded sleeve 42 is a support plate 421, the size of which is larger than the hole size of the reinforcing mesh 41. During the installation of the reinforcing mesh 41 and the embedded sleeve 42, the reinforcing mesh 41 passes through the top of the embedded sleeve 42. The support plate 421 cannot pass through the bottom of the reinforcing mesh 41, so the embedded sleeve 42 is tied to the reinforcing mesh 41 with cable ties, thereby fixing the position of the embedded sleeve 42. The top surface of the embedded sleeve 42 is located above the protective layer 3.

[0027] Positioning frames 51 are installed on the protective layer 3, with adjacent positioning frames 51 fitting together. A connector 511 is provided on the left side of each positioning frame 51, and a slot 512 is provided on the right side. When connecting the left and right positioning frames 51, a connector 511 is inserted into the slot 512 of the adjacent positioning frame 51, after which the sidewalls of the two positioning frames 51 fit together to form a single unit. Gabions 52 prevent water from flowing through the positioning frames 51, dispersing rainwater and reducing the water-bearing pressure on the geotechnical slope.

[0028] The connector 511 and the connector slot 512 are provided with connection holes, which are located above the embedded sleeve 42. During installation, the bottom connection hole of the connector slot 512 is placed above the embedded sleeve 42. After the connector 511 is inserted, the connection hole of the connector 511 is also located above the embedded sleeve 42. The positioning of the positioning frame 51 is completed through the connection hole and the embedded sleeve 42.

[0029] The drainage mechanism 5 also includes a fixing bolt 53, which is used to fix the position of the positioning frame 51. The bottom of the fixing bolt 53 is a screw 531, and the top of the fixing bolt 53 is a crossbar 532. The screw 531 passes through the connection hole of the plug connector 511 and the plug slot 512, and the bottom of the screw 531 is screwed to the pre-embedded sleeve 42. In use, the screw 531 is inserted into the connection hole and screwed into the pre-embedded sleeve 42, thereby restricting the movement of the positioning frame 51.

[0030] The length of the crossbar 532 is greater than the side length of the two positioning frames 51. By operating the crossbar 532, the screw 531 is rotated. When the screw 531 is screwed in, the bottom surface of the crossbar 532 is in contact with the surface of the positioning frame 51. When the crossbar 532 is rotated to the correct position, both ends of the crossbar 532 are above or in contact with the gabion 52. The crossbar 532 further presses the gabion 52, making it impossible for the gabion 52 to fall off.

[0031] Water passage channels 513 are provided at the upper and lower parts of the positioning frame 51. The water passage channels 513 between adjacent positioning frames 51 are connected. When there is water at the slope, the water in the gabion 52 flows downward through the water passage channels 513 and eventually enters the drainage ditch, reducing the seepage of water into the slope.

[0032] To further enhance the stability of the gabion 52, the upper and lower gabions 52 are connected by tie hooks 521, which hold the edges of the gabion 52 and are located above the water channel 513. Connecting the vertical gabions 52 into a whole can effectively reduce the swaying and sliding of individual gabions 52.

[0033] The top of the positioning frame 51 is provided with a connecting post 514, and the protective net 6 is wrapped around the connecting post 514. The protective net 6 covers the gabion 52 and the positioning frame 51, reducing the risk of gravel slipping out of the gabion 52.

[0034] This structure utilizes the hydrophobicity of the gabion 52 to drain water downwards, while some of the water that seeps in passes through the protective layer 3 and the waterproof membrane 2, keeping most of the water outside the waterproof membrane 2, thus keeping the interior of the geotechnical slope dry and ensuring the stability of the geotechnical slope.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
