Description

Technical Field

[0001] This invention relates to the field of geotechnical engineering technology, and more specifically, to a seepage-proof structure for geotechnical engineering slopes. Background Technology

[0002] Geotechnical engineering slopes refer to earthen slope structures along the sides of roads, etc., reinforced by piling rocks on top. However, due to the water permeability of rock crevices and soil fissures at the base of the rocks, rainwater can seep into the slope's interior during rainfall, causing the soil to become loose and prone to natural disasters such as landslides and mudslides.

[0003] Chinese invention patent CN110924381A discloses a seepage-proof structure for a geotechnical engineering slope, including a slope body and a water-blocking channel set on the upper part of the slope body. A dam is set at the bottom of the slope body, and a drainage channel is set on the side of the dam away from the slope body. The surface of the slope body is covered with a primary seepage-proof layer. The surface of the water-blocking channel and the primary seepage-proof layer is connected to the drainage channel. A secondary seepage-proof layer is set between the slope body and the primary seepage-proof layer. The secondary seepage-proof layer includes a first ground film layer set on the surface of the slope body, a gravel soil layer set on the surface of the first ground film layer, and a second ground film layer set on the surface of the gravel soil layer. The part of the dam that contacts the secondary seepage-proof layer is a permeable layer. A water storage cavity adjacent to the permeable layer is set inside the dam. The water storage cavity is connected to the drainage channel through a first drainage pipe.

[0004] As described in the prior art above, and in combination with Figure 1 Currently, most waterproofing structures involve setting a waterproofing layer 02 on the surface of rock 01 piled on a slope, such as a concrete reinforcement layer or a ground membrane layer, which can achieve waterproofing in one step. However, the concrete reinforcement layer structure damages the structure of the rock 01 itself (the two are completely fused together), making it difficult to reuse the rock; the waterproofing layer 02 structure has multiple layers on the surface of the geotechnical engineering, making the removal of the rock 01 structure more complicated. Therefore, improvements are needed. Summary of the Invention

[0005] In response to the technical problem mentioned in the background art that concrete reinforcement layers and mulch layers easily damage the individual rock structure, making it difficult to reuse the rock, this invention utilizes a seepage prevention mechanism set at the top of the slope to achieve a better seepage prevention purpose without damaging the individual rock structure, and it is very convenient for slope modification or rock reuse.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A seepage-proof structure for a geotechnical engineering slope includes: a soil slope, a rock layer, and one or more seepage-proof mechanisms. The rock layer is located on the slope surface of the soil slope and is divided into multiple rock units. Drainage channels are provided between the multiple rock units. The seepage-proof mechanisms are located at the top of the soil slope and are located between adjacent drainage channels.

[0008] The waterproof mechanism includes a housing, a rotating shaft, a waterproof plate, and a driving component;

[0009] The box body includes a shell, a left side plate and a right side plate. The rotating shaft is rotatably installed between the left side plate and the right side plate. The driving component is driven to connect with the rotating shaft. One side of the waterproof plate is fixed on the rotating shaft and performs a winding and unfolding action when the rotating shaft rotates.

[0010] The waterproof board includes one or more horizontal unit plates, which are arranged parallel to the rotating shaft. Adjacent horizontal unit plates are hinged together, and a horizontal water conveying channel is provided on the horizontal unit plate. The two ends of the horizontal water conveying channel are connected to the drainage channel.

[0011] With the above technical solution, when carrying out seepage prevention and protection construction on soil slopes (such as geological slopes along highways), the slope is not necessarily straight in the length direction because it curves with the highway. Therefore, it is necessary to set up multiple sets of seepage prevention mechanisms to protect the curved soil slopes. This is a necessary condition for seepage prevention and protection construction on curved slopes. At the same time, drainage channels are built between the multiple sets of seepage prevention mechanisms. The drainage channels can be made of concrete or pre-set soil channels, and then plastic or metal drainage channels are installed in the soil channels.

[0012] When it rains, all waterproofing mechanisms are activated (manually or automatically). Rainwater falls onto the surface of the waterproofing board and flows along the transverse water channels into the drainage channel for discharge.

[0013] After the rainy weather ends, close all waterproofing mechanisms (manually or automatically). If the waterproofing panels are made of metal, they can be dried using a drying device to prevent long-term corrosion from rainwater and extend their service life.

[0014] The advantages of this invention are: the solution utilizes a seepage-proof mechanism installed at the top of the slope, which has good seepage-proof performance and can avoid damaging the individual rock structure, making it very convenient for slope modification or rock reuse.

[0015] The present invention is further configured such that the drainage trough and the transverse water conveyance trough are arranged perpendicularly to each other.

[0016] The above technical solution facilitates the winding of the waterproof board. If a longitudinal water inlet is set, the winding operation will be impossible in the water inlet.

[0017] The present invention is further configured such that: the waterproof plate includes a functional part and one or more positioning parts, the rotating shaft includes a main body and one or more positioning rings, the positioning part is fixed between adjacent positioning rings, the functional part is fixed on the bottom edge of the positioning part, and the transverse water conveying groove is provided on the functional part.

[0018] The above technical solution uses a positioning ring to pre-wind the positioning part, so that the functional part can be accurately wound onto the rotating shaft during repeated winding and unwinding, and is not prone to deviation.

[0019] The present invention is further configured such that the drainage trough is constructed by installing a concrete-formed or prefabricated drainage trough body.

[0020] Through the above technical solutions, the drainage channel can be constructed with concrete or a pre-set earthen channel, and then a plastic or metal drainage channel can be installed in the earthen channel.

[0021] The present invention is further configured such that the transverse water conveying trough can be tilted within the width range of a single transverse unit plate.

[0022] The purpose of the above technical solution, which involves tilting the device, is to accelerate rainwater output and improve drainage efficiency.

[0023] The present invention is further configured such that when the waterproof plate is configured as a metal plate, a drying device is installed inside the waterproof mechanism.

[0024] The above technical solution addresses the issue that metal waterproofing boards are prone to corrosion during prolonged contact with rainwater. By installing a drying device to accelerate the drying of the waterproofing boards after use, corrosion can be effectively prevented, and the service life of the waterproofing boards can be extended.

[0025] The present invention is further configured such that: the drying device includes a heating wire and a blower fan, the heating wire is fixed on the inner wall of the right side plate, and the blower fan is rotatably mounted on the inner wall of the right side plate.

[0026] Through the above technical solution, the blower fan blows the hot air emitted by the heating wire toward the waterproof plate to achieve the drying effect.

[0027] The present invention is further configured such that the axial direction of the blower fan is parallel to the axial direction of the rotating shaft.

[0028] The above technical solution maintains the correct direction of hot air output.

[0029] The present invention is further configured such that the widths of adjacent waterproofing mechanisms are not equal.

[0030] With the above technical solution, since the rock slope may be a curved slope structure, that is, the slope is not necessarily a straight line in the length direction, it is necessary to set up multiple sets of seepage prevention mechanisms to protect the curved soil slope. Among them, when the slope is at a bend, the width of the seepage prevention mechanism can be set to be smaller to meet the usage requirements of the bend position.

[0031] The present invention is further configured such that the driving component is a motor.

[0032] Through the above technical solution, the motor can drive the shaft to rotate, or other driving components can be used.

[0033] In summary, the present invention has the following beneficial effects:

[0034] (1) The present invention utilizes a seepage prevention mechanism set at the top of the slope. Based on its good seepage prevention performance, it can avoid damaging the individual rock structure, and is therefore very convenient for slope modification or rock reuse.

[0035] (2) The present invention can be applied to seepage prevention structures for curved rock slopes along highways;

[0036] (3) After the seepage prevention mechanism in the present invention is closed, the original appearance of the rock slope can be maintained, thereby maintaining the unique appearance of the rock slope and allowing the rock to take deeper root on the soil slope over time, making the slope more solid.

Detailed Implementation

[0044] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0045] A seepage-proof structure for geotechnical engineering slopes, such as Figures 2-4 As shown, the structure includes: an earthen slope 1, a rock layer 2, and one or more anti-seepage mechanisms 3. The rock layer 2 is located on the slope surface of the earthen slope 1. During construction, the rock layer 2 on the slope surface is divided into multiple rock units 2-1 by setting drainage channels 2-2. Therefore, drainage channels 2-2 are provided between the multiple rock units 2-1 to drain rainwater from the slope surface of the earthen slope 1. So, how is rainwater collected from the slope surface of the earthen slope 1? The anti-seepage mechanism 3 is provided to collect rainwater from the slope surface of the earthen slope 1, and the anti-seepage mechanism 3 is located at the top of the earthen slope 1 and between adjacent drainage channels 2-2.

[0046] Among them, such as Figure 5 and Figure 6 As shown, the waterproofing mechanism 3 comprises four parts: a metal housing 4, a metal rotating shaft 5, a metal waterproofing plate 6, and a driving component 7. The housing 4 is used to install the remaining components (rotating shaft 5, waterproofing plate 6, and driving component 7), and the housing 4 is located at the top of the soil slope 1 and between adjacent drainage channels 2-2. Specifically, the housing 4 includes a shell 4-1, a left side plate 4-2, and a right side plate 4-3, which are fixed together with screws and have an outlet for the expansion and retraction of the waterproofing plate 6.

[0047] The rotating shaft 5 is rotatably mounted between the left side plate 4-2 and the right side plate 4-3. The driving component 7 is mounted on the outside of the right side plate 4-3. In this case, the driving component 7 is configured as a motor, and the driving component 7 and the rotating shaft 5 are drivenly connected. When the driving component 7 is activated, it can control the unfolding or rewinding action of the waterproof sheet 6. One side of the waterproof sheet 6 is fixed to the rotating shaft 5 and performs the rewinding and unfolding actions when the rotating shaft 5 rotates.

[0048] In this embodiment, the waterproof board 6 includes a functional part 8 and three positioning parts 9. The rotating shaft 5 includes a main body 5-1 and four positioning rings 5-2. The positioning parts 9 are fixed between adjacent positioning rings 5-2, and the functional part 8 is fixed to the bottom edge of the positioning part 9. The positioning rings 5-2 pre-wind the positioning part 9, so that the functional part 8 can be accurately wound onto the rotating shaft 5 during repeated winding and unwinding, and is not prone to deviation.

[0049] The waterproof plate 6 on the functional part 8 includes one or more horizontal unit plates 6-1. The horizontal unit plates 6-1 are arranged parallel to each other with the rotating shaft 5. Adjacent horizontal unit plates 6-1 are hinged together, and a horizontal water conveying channel 6-11 is provided on the horizontal unit plate 6-1. The two ends of the horizontal water conveying channel 6-11 are connected to the drainage channel 2-2. In this embodiment, the drainage channel 2-2 and the horizontal water conveying channel 6-11 are arranged perpendicularly to each other. Of course, in other embodiments, the drainage channel 2-2 and the horizontal water conveying channel 6-11 can be arranged at other angles, as long as the rainwater in the horizontal water conveying channel 6-11 is collected into the drainage channel 2-2. In addition, the horizontal water conveying channel 6-11 can be inclined within the width range of a single horizontal unit plate 6-1. The purpose of the inclined arrangement is to accelerate the output of rainwater and improve drainage efficiency.

[0050] During construction, drainage channel 2-2 is constructed by installing a concrete-formed or prefabricated drainage channel body. The prefabricated drainage channel body is generally a plastic channel body or a metal channel body.

[0051] Furthermore, when the waterproofing plate 6 is configured as a metal plate, a drying device 0 is installed inside the waterproofing mechanism 3. The drying device 0 includes a heating wire 0-1 and a blower fan 0-2. The heating wire 0-1 is fixed to the inner wall of the right side plate 4-3, and the blower fan 0-2 is rotatably mounted on the inner wall of the right side plate 4-3. The axial direction of the blower fan 0-2 is parallel to the axial direction of the rotating shaft 5.

[0052] Finally, taking a rock slope on the side of a highway as an example, since the rock slope on the side of a highway has straight sections and curved sections, the widths of adjacent anti-seepage mechanisms 3 are set differently. In straight sections, the width of the anti-seepage mechanism 3 can be set larger, thereby improving the construction efficiency of the anti-seepage mechanism 3. However, in curved sections, the width of the anti-seepage mechanism 3 needs to be set smaller to prevent the curved rock slope from affecting the extension and retraction of the anti-seepage board 6 in the anti-seepage mechanism 3.

[0053] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
