Description

Technical Field

[0001] This utility model relates to the technical field of slope protection, and in particular to an ecological slope protection method that is beneficial to soil and water conservation. Background Technology

[0002] To ensure the stability of the roadbed, slopes with a certain gradient are constructed on both sides of the roadbed. Rainwater erosion can cause soil loss on the slopes, so slope protection and reinforcement are often carried out through the interaction between vegetation roots and the soil.

[0003] For example, Chinese utility model patent with publication number CN207512693U discloses an ecological slope protection block and its ecological slope protection, including a slope protection block body and / or a slope protection block assembly. The edge of the slope protection block body or the slope protection block assembly is provided with an outward protruding buckle and an inward self-locking groove. Adjacent ecological slope protection blocks are interlocked by corresponding outward protruding buckles and inward self-locking grooves. Its installation and construction are simple. After the adjacent ecological slope protection blocks are interlocked, the positioning reliability is further improved by threading steel ropes.

[0004] However, the above-mentioned device still has the following defects: the planting holes on the block body allow vegetation to grow on the slope. When the rain is too heavy, the rainwater will seep into the slope through the planting holes. If the amount of rainwater seeping in is too large, it will cause the slope to landslide, which poses a great hidden danger. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides an ecological slope protection that is conducive to soil and water conservation, which can satisfy vegetation growth while preventing excessive rainwater from seeping into the slope and reducing the rate of landslide accidents.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ecological slope protection system conducive to soil and water conservation, comprising a slope body and multiple masonry blocks arranged on the inclined surface of the slope body. Symmetrically arranged semi-through grooves are provided on the left and right sides of each masonry block. When the semi-through grooves on two adjacent left and right masonry blocks are closed, they form a planting trough allowing vegetation to pass through. Symmetrically arranged semi-grooves are provided on the upper and lower sides of each masonry block. When the semi-grooves on two adjacent upper and lower masonry blocks are closed, they form a water guiding trough. Each masonry block is provided with a Venturi tube connecting the two semi-grooves and two connecting pipes. One end of each connecting pipe is connected to the interior of the two semi-through grooves, and the other end of each connecting pipe is connected to the necking point on the Venturi tube. Further, the semi-through grooves are preferably semi-circular, but square, rhomboid, or other shapes can also be used as needed.

[0007] Preferably, the bottom of the masonry block is provided with a socket block, and the lower part of the masonry block is provided with a socket slot that fits with the socket block. The socket block on the upper set of masonry blocks of the slope body is inserted into the socket slot on the lower adjacent set of masonry blocks.

[0008] Preferably, the upper and lower parts of the slope body are provided with drainage ditches, and the drainage ditches are provided with openings that communicate with the water guide channel.

[0009] Preferably, it also includes multiple longitudinal beams set on the slope body, with the two ends of the longitudinal beams respectively connected to two drainage ditches, and the masonry blocks arranged within a rectangular frame formed by two adjacent longitudinal beams and two drainage ditches; furthermore, both the longitudinal beams and drainage ditches adopt a concrete integral casting structure.

[0010] Preferably, it also includes a tie anchor, one end of which extends into the slope body and the other end of which is connected to the longitudinal beam; further, there may be one or more tie anchors.

[0011] Preferably, the connecting pipe extends into the semi-penetrating groove at a height of 2-3 cm above the bottom of the masonry block, and one end of the connecting pipe extending into the semi-penetrating groove is higher than the end connected to the Venturi pipe; furthermore, when the diameter of the vegetation trough is larger, the distance between the connecting pipe and the semi-penetrating groove and the bottom of the masonry block is smaller, so as to ensure that the vegetation trough absorbs some rainwater while avoiding excessive rainwater retention in the vegetation trough.

[0012] Preferably, the water guide channel is a conical channel, with the larger diameter end of the conical channel being far away from the slope body.

[0013] Preferably, the upper inlet end of the Venturi tube is provided with a filter screen; further, the filter screen is parallel to the bottom edge of the conical groove.

[0014] Compared with existing technologies, this utility model provides an ecological slope protection system that is beneficial to soil and water conservation, with the following advantages: Under normal rainfall conditions, some rainwater falls into the vegetation trough and seeps into the slope body, while some rainwater flows downward through the drainage channel and Venturi pipe. When heavy rain occurs, rainwater in the vegetation trough cannot be discharged in time. At this time, the rainwater collected in the drainage channel flows into the Venturi pipe. The constriction of the Venturi pipe generates negative pressure, and the rainwater accumulated in the vegetation trough is drawn into the Venturi pipe through the connecting pipe, effectively reducing the amount of rainwater accumulated in the vegetation trough. This satisfies the needs of vegetation growth while reducing the excessive infiltration of rainwater into the slope body through the vegetation trough, thereby reducing the rate of slope landslides.

Detailed Implementation To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0016] An ecological slope protection block and its ecological slope protection as described in the background art; the planting holes on the block body allow vegetation to grow on the slope. When the rainfall is too heavy, the rainwater will seep into the slope through the planting holes. If the amount of rainwater seeping in is too large, it will cause the slope to landslide, which poses a great hidden danger.

[0017] To solve this technical problem, this utility model provides an ecological slope protection method that is beneficial to soil and water conservation and is applied to slope protection.

[0018] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0019] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0020] Example 1 Please refer to Figures 1-3 as well as Figures 5-9An ecological slope protection method conducive to soil and water conservation includes a slope body 1 and multiple masonry blocks 2 arranged on the sloping surface of the slope body 1. Symmetrically arranged semi-through grooves 3 are provided on the left and right sides of the masonry blocks 2. When the semi-through grooves 3 on two adjacent left and right masonry blocks 2 are closed, they form a planting trough that allows vegetation to pass through. Symmetrically arranged semi-recesses 4 are provided on the upper and lower sides of the masonry blocks 2. When the semi-recesses 4 on two adjacent upper and lower masonry blocks 2 are closed, they form a water guiding channel. Venturi pipes 5 and two connecting pipes 6 are provided on the masonry blocks 2, connecting the two semi-recesses 4. One end of each connecting pipe 6 is connected to the interior of the two semi-through grooves 3, and the other end of each connecting pipe 6 is connected to the necking point on the Venturi pipe 5. Further, the semi-through grooves 3 are preferably semi-circular, but square, rhomboid, or other shapes can also be used as needed.

[0021] For details, please refer to Figures 6-8 The bottom of the masonry block 2 is provided with a socket block 7, and the lower part of the masonry block 2 is provided with a socket slot 8 that fits with the socket block 7. The socket block 7 on the upper set of masonry blocks 2 of the slope body 1 is inserted into the socket slot 8 on the lower adjacent set of masonry blocks 2.

[0022] For details, please refer to Figure 1 as well as Figure 6 The water guide channel is a conical channel, with the large-diameter end of the conical channel far away from the slope body 1.

[0023] For details, please refer to Figures 7-8 A filter screen 13 is provided at the upper inlet end of the Venturi pipe 5; furthermore, the filter screen 13 is parallel to the bottom edge of the conical groove.

[0024] For details, please refer to Figure 9 The connecting pipe 6 extends into the semi-penetrating groove 3, 2-3 cm above the bottom of the masonry block 2. One end of the connecting pipe 6 extending into the semi-penetrating groove 3 is higher than the end connected to the Venturi pipe 5. Furthermore, when the aperture of the vegetation trough is larger, the distance between the connecting pipe 6 and the semi-penetrating groove 3 and the bottom of the masonry block 2 is smaller. This ensures that the vegetation trough absorbs some rainwater while preventing excessive rainwater from remaining in the vegetation trough. This arrangement ensures that some rainwater seeps into the slope body 1 through the vegetation trough, while further preventing excessive rainwater from accumulating in the vegetation trough. The inlet end of the connecting pipe 6 is higher than the outlet end, which allows the rainwater accumulated in the vegetation trough to be more smoothly drawn into the Venturi pipe 5, ensuring that excessive rainwater in the vegetation trough is discharged in a timely manner.

[0025] The ecological slope protection provided in this embodiment, which is beneficial to soil and water conservation, connects two adjacent masonry blocks 2 into one unit through socket blocks 7 and socket slots 8, making the blocks in the same row connected as a whole, which is convenient for construction and improves the installation stability of the masonry blocks 2 at the slope body 1, making them less susceptible to rainwater impact. The filter screen 13 can reduce the entry of particulate matter into the Venturi pipe 5, avoiding blockage at the neck of the Venturi pipe 5. The water guide channel adopts a conical channel, which can increase the water collection area and facilitate the formation of full flow in the Venturi pipe 5. The bottom edge of the filter screen 13 is parallel to the bottom edge of the conical channel, which can reduce the accumulation of sand and gravel particles at the conical channel and facilitate the washing off of particles at the filter screen 13 by rainwater.

[0026] Example 2 The ecological slope protection blocks and their ecological slope protection provided in Example 1 have been further optimized. For details, please refer to... Figures 1-3 The upper and lower parts of the slope body 1 are provided with drainage ditches 9, and the drainage ditches 9 are provided with openings 10 that are connected to the water guide channel.

[0027] For details, please refer to Figures 1-4 It also includes multiple longitudinal beams 11 set on the slope body 1, with the two ends of the longitudinal beams 11 connected to two drainage ditches 9 respectively, and the masonry blocks 2 arranged in the rectangular frame formed by the two adjacent longitudinal beams 11 and the two drainage ditches 9; furthermore, the longitudinal beams 11 and the drainage ditches 9 are both made of integrally cast concrete.

[0028] For details, please refer to Figure 4 It also includes a tie anchor 12, one end of which extends into the slope body 1, and the other end of which is connected to the longitudinal beam 11; furthermore, the tie anchor 12 can be one or more.

[0029] The ecological slope protection provided in this embodiment, which is beneficial to soil and water conservation, allows rainwater in the drainage ditch 9 to enter the water guide channel through the opening 10 and flow into the lower drainage ditch 9. This eliminates the need to set up a water guide channel at the slope body 1, improves the drainage uniformity of the upper drainage ditch 9, and avoids concentrated drainage at the slope body 1, which could cause erosion of the slope body 1. The longitudinal beam 11 can provide a good anti-slide effect for the slope body 1 and improve its anti-slide performance. The anchor 12 can provide tension for the longitudinal beam 11, thereby improving the installation stability of the longitudinal beam 11 at the slope body 1 and further reducing the risk of slope landslide.

[0030] The application process of the ecological slope protection that benefits soil and water conservation provided by this utility model is as follows: Under normal rainfall, some rainwater falls into the vegetation trough and seeps into the slope body 1 through the vegetation trough to support vegetation growth; some rainwater flows downward through the drainage channel and Venturi pipe 5; when there is heavy rain, the rainwater in the vegetation trough is difficult to drain in time, and the rainwater in the drainage ditch 9 at the top of the slope body 1 flows into the drainage channel through the opening 10. The rainwater collected in the drainage channel flows into the Venturi pipe 5. The constriction of the Venturi pipe 5 generates negative pressure, and the rainwater accumulated in the vegetation trough is sucked into the Venturi pipe 5 through the connecting pipe 6, effectively reducing the amount of rainwater accumulated in the vegetation trough and preventing excessive rainwater from seeping into the slope body 1. In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
