Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of slope protection, in particular to an ecological slope protection structure. BACKGROUND

[0002] Slope soil body sliding is a serious geological disaster phenomenon, which not only threatens the safety of residents' lives, but also brings certain difficulty to engineering construction. Moreover, the slope soil body sliding is long-term and irregular, and the current protection technology is mostly a structural protection mode based on a frame and a pile body. In the protection process, although the frame and the pile body can play a role in reinforcing the soil body and the rock-soil layer, due to the rigid connection mode of the frame and the pile body, when the pile body inserted into the slope surface is stressed to produce deformation or displacement, the frame at the slope surface is easily deformed or damaged by the rigid external force of the pile body, thereby shortening the service life of the slope protection and increasing the maintenance cost.

[0041] Please refer to Figures 1-7 The embodiment provides an ecological slope protection structure 100, which comprises a plurality of slope surface frame units 110, and the plurality of slope surface frame units 110 are arranged in an array; each slope surface frame unit 110 comprises a frame main body 120 and a plurality of first anchoring units 130, and the frame main body 120 encloses an ecological vegetation area 101.

[0042] The first anchoring unit 130 comprises a first fixed end 131, a first anchor rod 132, a second anchor rod 133, an anchoring sleeve 134, an anchor cable 135 and a first anchoring end 136; the first fixed end 131 is connected with the frame main body 120, two ends of the first anchor rod 132 are connected with the fixed end and the anchoring sleeve 134 respectively, two ends of the second anchor rod 133 are connected with the anchoring sleeve 134 and the anchor cable 135 respectively, and the first anchoring end 136 is connected to one end of the anchor cable 135 away from the second anchor rod 133.

[0043] Among them, the first anchor rod 132, the second anchor rod 133, the anchoring sleeve 134 and the anchor cable 135 extend in the same direction, and the anchoring sleeve 134 and the first anchoring end 136 are anchored in the rock-soil layer 10 below the slope.

[0044] Please refer toFigures 1-7 The working principle of the ecological slope protection structure 100 is as follows:

[0045] Firstly, the ecological slope protection structure 100 comprises a plurality of slope surface frame units 110, which are arranged in an array; each slope surface frame unit 110 comprises a frame main body 120 and a plurality of first anchoring units 130, and the frame main body 120 encloses an ecological vegetation area 101; therefore, through such a setting mode, the slope surface can be reinforced at multiple points by arranging the plurality of slope surface frame units 110 in an array, and a plurality of ecological vegetation areas 101 are formed, and slope protection plants can be planted in the ecological vegetation areas 101, so as to combine ecological protection with structural protection, thereby improving the stability of the slope;

[0046] Secondly, when the plurality of slope surface frame units 110 are arranged, the frame main body 120 is arranged on the surface of the slope, and the frame main body 120 is fixed to the slope by anchoring the plurality of first anchoring units 130 to the rock-soil layer 10 of the slope body, thereby playing a protective role on the slope;

[0047] The stress size of anchoring, the depth of anchoring, the related structural size and the number of the plurality of first anchoring units 130 can be adjusted according to specific protection requirements;

[0048] Moreover, when the first anchoring unit 130 is arranged, it comprises a first fixed end 131, a first anchor rod 132, a second anchor rod 133, an anchoring sleeve 134, an anchor cable 135 and a first anchoring end 136; through such a structural arrangement, when it is anchored to the rock-soil layer 10 of the slope, the first fixed end 131 is connected with the frame main body 120, the two ends of the first anchor rod 132 are respectively connected with the fixed end and the anchoring sleeve 134, the two ends of the second anchor rod 133 are respectively connected with the anchoring sleeve 134 and the anchor cable 135, and the first anchoring end 136 is connected to one end of the anchor cable 135 away from the second anchor rod 133;

[0049] Moreover, the first anchor rod 132, the second anchor rod 133, the anchoring sleeve 134 and the anchor cable 135 extend in the same direction to determine the anchoring depth, and the anchoring sleeve 134 and the first anchoring end 136 are both anchored in the rock-soil layer 10 below the slope, i.e. the anchoring sleeve 134 and the first anchoring end 136 are both anchored in the rock-soil layer 10 of the slope, so that the first anchoring unit 130 has two anchoring points in the rock-soil layer 10 of the slope, which are respectively determined by the anchoring sleeve 134 and the first anchoring end 136 and are spaced apart along the depth direction of anchoring;

[0050] Based on this, since the first anchor rod 132 is arranged between the first fixed end 131 and the anchoring sleeve 134, the corresponding support can be formed by the first anchor rod 132, the first fixed end 131 and the anchoring sleeve 134, thereby improving the overall support strength, improving the anti-sliding and anti-displacement effect on the slope soil body, and improving the stability of the structure;

[0051] The anchor cable 135 is arranged between the anchoring sleeve 134 and the first anchoring end 136. By arranging the anchor cable 135, a certain flexible support can be formed in the rock-soil layer 10 of the slope. Based on the arrangement of the flexible support, when the soil body in the rock-soil layer 10 slips or deforms, the corresponding deformation of the anchor cable 135 or the position change of the first anchoring end 136 can be used to absorb the corresponding deformation external force, thereby absorbing the corresponding rigid external force in this way, avoiding displacement or damage of the overall structure due to a large external force;

[0052] In addition, based on the above structure, when the first anchoring unit 130 is arranged, the first anchor rod 132, the first fixed end 131 and the anchoring sleeve 134 can form a rigid support area in a part of the area under the slope, and the anchor cable 135, the anchoring sleeve 134 and the first anchoring end 136 form a flexible support area, and the depth of the flexible support area is greater than the depth of the rigid support area. Therefore, since the anchoring sleeve 134 is connected with the first anchor rod 132 and the second anchor rod 133, and the second anchor rod 133 is connected with the anchor cable 135, the flexible support area and the rigid support area can be connected in series, so that the flexible support area can not only absorb the displacement or deformation of the soil body in the area where it is located, but also absorb the overall displacement or deformation of the rigid support area. In this way, the stability of the support can be improved, and the deformation or displacement adaptability of the rock-soil layer 10 can be improved, that is, the ecological slope protection structure 100 is formed in the combination of flexible support and rigid support;

[0053] In summary, the ecological slope protection structure 100 can play a protection and reinforcement role on the slope, and in the process of protection and reinforcement, the external protection structure can be protected correspondingly, so that the external structure will not be deformed or damaged due to rigid external force in the protection process, thereby prolonging the protection period of the structure, prolonging the service life and reducing the maintenance cost.

[0054] Based on the above structure, please refer to Figures 1-8In the configuration of the anchoring sleeve 134, the anchoring cavity 137 is arranged in the anchoring sleeve 134, and one end of the first anchor rod 132 and one end of the second anchor rod 133 extend into the anchoring cavity 137; wherein, along the extension direction of the anchoring sleeve 134, the two ends of the anchoring cavity 137 are respectively provided with the first abutting portion 138 and the second abutting portion 139, and the first abutting portion 138 and the second abutting portion 139 are respectively used to limit the first anchor rod 132 and the second anchor rod 133 from being separated from the anchoring cavity 137. Thus, by such a setting mode, the stability of the connection can be increased.

[0055] On the basis of the structure of the anchoring sleeve 134 described above, the second anchor rod 133 can be connected with a sliding ring 141 at the part located in the anchoring cavity 137, the inner wall of the anchoring cavity 137 is provided with a pressure relief protrusion 142, the end face of the pressure relief protrusion 142 is provided with a transition arc surface, the pressure relief protrusion 142 is spaced from the second abutting portion 139, and the pressure relief protrusion 142 abuts against the sliding ring 141;

[0056] Wherein, the second anchor rod 133 is used to move in the direction of extending out of the anchoring cavity 137 under the action of an external force, so that the sliding ring 141 contacts the pressure relief protrusion 142 and slides towards the second abutting portion 139, and then the pressure relief support is formed by the deformation of one or more of the pressure relief protrusion 142, the sliding ring 141, the anchoring sleeve 134 and the second anchor rod 133.

[0057] That is, by the above structure, the pressure relief support between the second anchor rod 133 and the anchoring sleeve 134 can be formed, and then the corresponding supporting effect can be formed by such a setting mode, and has a certain ability to adapt to the deformation or displacement of the rock-soil layer 10, and then can be further combined with the flexible support and the rigid support described above to improve the overall protection effect of the ecological slope protection structure 100. It should be noted that, since the pressure relief protrusion 142 is spaced from the second abutting portion 139, during the sliding of the sliding ring 141 relative to the anchoring cavity 137, it abuts against the second abutting portion 139 after being pressed to the end, at this time, the support between the second anchor rod 133 and the anchoring sleeve 134 is a rigid support.

[0058] On the basis of the above structure, please refer to Figures 1-8To improve the protection stability of the ecological slope protection structure 100 as a whole, the slope surface frame unit 110 further comprises a plurality of second anchoring units 150, each of which comprises a second fixed end 151, a third anchor rod 152 and a second anchoring end 153; the second fixed end 151 is connected with the frame body 120, the two ends of the third anchor rod 152 are respectively connected with the second fixed end 151 and the second anchoring end 153, and the second anchoring end 153 is anchored in the rock-soil layer 10 below the slope; wherein the anchoring depth of the first anchoring end 136 is greater than the anchoring depth of the second anchoring end 153. Moreover, the anchoring depth of the anchoring sleeve 134 is greater than the anchoring depth of the second anchoring end 153.

[0059] The purpose of such a setting mode is to divide the rock-soil layer 10 below the slope into a flexible supporting area and a rigid supporting area according to the depth, and the depth of the flexible supporting area is greater than that of the rigid supporting area, so as to improve the stability of the rigid supporting area by the deformation of the flexible supporting area, thereby playing a corresponding protection role on the external frame body 120 and being beneficial to the protection of the slope.

[0060] Further, please refer to Figures 1-8 In the embodiment, when the frame body 120 is configured, the frame body 120 comprises two first side frames 121 and two second side frames 122, which together enclose the ecological vegetation area 101, and the two first side frames 121 are oppositely and parallelly arranged, and the two second side frames 122 are oppositely and parallelly arranged.

[0061] Among them, the first side frame 121 is arranged along the slope surface inclination direction, the second side frame 122 is arranged along the horizontal direction, and each first side frame 121 is connected with at least one first anchoring unit 130, and each second side frame 122 is connected with at least one second anchoring unit 150.

[0062] Therefore, on the basis of the above structure, the relative positions of the first anchoring unit 130 and the second anchoring unit 150 can also be adjusted according to specific protection requirements, and on the basis of the above content, the second anchoring unit 150 can also be installed on the first side frame 121, and for the same reason, the first anchoring unit 130 can also be installed on the second side frame 122, that is, the position setting and the number of the first anchoring unit 130 and the second anchoring unit 150 can be selectively set according to the specific protection requirements of the slope.

[0063] Please refer to Figures 1-8When installing the first anchoring unit 130, taking the connection between the first anchoring unit 130 and the first frame 121 as an example, in order to facilitate the connection between the first fixed end 131 and the first frame 121, the first frame 121 opens a first installation groove 123, and the bottom of the first installation groove 123 is provided with a tapered hole 124 that cooperates with the first fixed end 131. The inner diameter of the tapered hole 124 gradually decreases from the direction toward the slope, and the first fixed end 131 has a shape that cooperates with the tapered hole 124. Through such an arrangement, the contact area between the first fixed end 131 and the first frame 121 is increased to improve the stability of the support.

[0064] In addition, to facilitate forming the water channel 102 on the slope after the multiple slope frame units 110 are arranged in an array on the slope, the frame body 120 also includes two first abutting platforms 125 and two second abutting platforms 126. The outer sides of the two first side frames 121 are respectively connected to a first abutting platform 125 and a second abutting platform 126, and the outer sides of the two second side frames 122 are respectively connected to a first abutting platform 125 and a second abutting platform 126.

[0065] The first abutting platform 125 on the outer side of each first frame 121 is used to abut against the second abutting platform 126 on the outer side of the adjacent frame body 120 to form a water channel 102 between the two adjacent frame bodies 120 .

[0066] Therefore, please refer to Figures 1-8 Through the above-mentioned structural setting, after the frame arranges multiple slope frame units 110 in an array on the slope, based on the cooperation of the first supporting platform 125 and the second supporting platform 126 on the outer side of the adjacent frame body 120, a mesh-shaped water diversion channel 102 can be formed on the slope to improve the water diversion efficiency. Moreover, this setting method can slow down the flow rate of water to reduce the scouring effect of rainwater, thereby improving the stability of the soil.

[0067] In addition, as the protection time increases, there can be a certain displacement change or deformation between the plurality of slope frame units 110. To avoid misalignment between adjacent slope frame units 110 due to displacement change, and to avoid the occurrence of a situation in which the water channel 102 fails, one of the first and second abutting tables 125 and 126 is concave on the outer side, and the other is convex on the outer side, and they cooperate with each other to increase the contact area and improve stability in this way. Moreover, when there is a relative displacement change or deformation between the plurality of slope frame units 110, the deformation between the first and second abutting tables 125 and 126 can absorb the deformation stress between the two adjacent slope frame units 110, thereby reducing damage to the main structure of the two adjacent slope frame units 110 and reducing maintenance costs. Furthermore, to further slow down the flow rate of rainwater and reduce the erosion of the slope soil, each second side frame 122 is provided with a plurality of water guide grooves 127, which are arranged at an angle with respect to the extension direction of the second side frame 122.

[0068] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
