Description

Technical Field

[0001] The invention relates to the technical field of anchoring and piling, and in particular to a slope greening device. Background Art

[0002] The slope protection technologies used in slope engineering can be roughly divided into slope protection technologies based on ecological restoration and slope protection technologies based on slope stability. Specifically, slope protection technologies based on ecological restoration include ecological porous brick slope protection, wire mesh gabion slope protection, ecological frame slope protection and slope-leveling ecological brick slope protection, etc. This type of slope protection technology focuses on achieving the ecological functions of slope water storage and soil conservation, and beautifying the environment; slope protection technologies based on slope stability include anchor slope protection, anchor cable slope protection, concrete sprayed anchor slope protection, anchor cable frame beam slope protection, etc.

[0003] A Chinese patent document with authorization announcement number CN112663629B discloses an anchor rod-ecological long bag combined structural system for ecological restoration of steep rock slopes. The structural system uses special anchor nails to fix the ecological long bag on a longitudinally arranged flexible non-degradable rubber plate. On the premise that the anchor rod has ensured the stability of the slope, the ecological long bag combined structure is tied to the steep rock slope surface through a steel cable connecting the anchor rod and the rubber plate, ultimately forming a stable mechanical structural system.

[0004] When the eco-bag greening scheme is used in the slope greening scheme, the eco-bags are first arranged in a row on the slope, and then the eco-bags are fixed to the slope through anchor rods or protective nets. When the protective net fixing method is used, the protective net body has a low cost and a good fixing effect, but the construction workload is large. When the anchor rod fixing method is used, the anchor rod is usually a steel anchor rod, and the anchor rod body has a high cost, but the construction workload is small. Therefore, it is necessary to reduce the cost of the anchor rod to make up for the defect of high anchor rod fixing cost. Summary of the invention

[0005] The invention provides a slope greening device, aiming to solve the problem of high cost of an anchor rod body in the related art.

[0006] A slope greening device includes a plurality of eco-bags and an anchoring device for fixing the eco-bags on the slope, wherein the anchoring device includes:

[0007] An anchoring head, the top of which is elastically hinged with at least two barbed pieces, and an abutment portion is provided on the inner side of the barbed portion close to one end of the anchoring head;

[0008] A push tube, the inner diameter of which is larger than the anchor head;

[0009] The connecting rope includes a main rope and at least two branch ropes fixedly connected to the top of the main rope, the bottom of the main rope is fixedly connected to the anchor head, and the end of the branch rope away from the main rope is provided with a connecting assembly that matches with the branch rope on other anchoring devices;

[0010] The clamping assembly includes a sliding ring arranged at the connection between the main rope and the branch rope, the sliding ring is slidably matched with the push tube, an upwardly inclined elastic sheet is arranged on the sliding ring, and a clamping hole matched with the elastic sheet is opened on the wall of the push tube;

[0011] When the barbed piece passes through the bottom end from the top end of the push cylinder, the two barbed pieces rotate close to each other so that they can pass through the push cylinder, and the elastic piece passes through the inner side of the clamping hole. After the barbed piece passes through the push cylinder and unfolds, the sliding ring slides upward again to make the bottom end of the push cylinder abut against the abutting part, and the top of the elastic piece enters the clamping hole and flattens, so that the sliding ring is clamped with the push cylinder.

[0012] The effect is as follows: first a row of eco-bags is placed at the bottom of the slope, then the anchor head is inserted from the top of the push tube, and the two barbed pieces shrink inward after contacting the push tube, so that the anchor head and the barbed pieces pass through the bottom of the tube body, and the barbed pieces unfold after passing through the push tube, and then the support rope is lifted upward, and the top of the elastic piece enters the clamping hole and gradually flattens, so that the sliding ring is clamped with the push tube, and the support rope cannot be further lifted, and at the same time, the bottom end of the tube body abuts against the abutment part, and finally a piling device is used to apply pressure to the push tube, the anchor head passes through the eco-bag and is pressed below the ground, and then the push tube is pulled out, and the two support ropes are respectively connected to the support ropes on the two adjacent anchoring devices, so that a row of eco-bags are anchored.

[0013] Preferably, a plurality of barb rings are installed on the main rope, and a plurality of expansion strips inclined outward and upward are arranged along the circumference of the barb rings. The effect is that when the main rope is subjected to an upward pulling force, the expansion strips flip outward to expand and diffuse into the surrounding soil, thereby making the barb rings better anchored in the soil.

[0014] Preferably, the connecting assembly comprises bolts and nuts, and one end of each branch rope away from the main rope is connected to the bolt or the nut.

[0015] Preferably, the bolts and / or nuts are rotatably connected to the branch ropes, which has the effect of preventing the branch ropes from being twisted or untwisted and affecting the connection effect when connected to other branch ropes.

[0016] Preferably, the push cylinder includes a cylinder body and a cylinder cap, a sliding groove is provided on the top of the cylinder body, a guide block slidingly matched with the sliding groove is provided on the bottom of the cylinder cap, a cutting portion is provided at the bottom end of the guide block, and a through hole formed between the cutting portion and the sliding groove is a clamping hole. When the anchoring device is inserted into the ecological bag and the soil, the cylinder cap is compressed to cause the cutting portion to slide in the sliding groove, thereby cutting off the elastic sheet. The effect is that the connection of the clamping assembly is released during anchoring, thereby avoiding the anchoring head from being pulled out when the sleeve is pulled out after the anchoring is completed.

[0017] Preferably, an elastic reset member is installed between the barrel body and the barrel cap to keep the clamping hole at a size that allows the elastic sheet to pass through.

[0018] Preferably, a connection structure cooperating with a pile driving device is provided on the top of the tube cap, which has the effect of facilitating the cooperation with the pile driving device and pressing the anchoring device into the soil through the pile driving device.

[0019] Preferably, the branch rope of the anchoring device is connected to the branch rope on the adjacent anchoring device in the same row through a connecting assembly, so that the eco-bags in the same row are connected together.

[0020] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0021] The anchor head is passed through the eco-bag and pressed into the ground through the piling device and the push cylinder. The push cylinder is then pulled out and the two support ropes are connected to the support ropes on the two adjacent anchoring devices through bolts and nuts. This process is then repeated to lay and anchor the eco-bags on the slope from bottom to top. This reduces the setup cost and because the support ropes are interconnected, a row of eco-bags are connected, resulting in a better fixing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0032] like Figure 4 As shown, a slope greening device includes eco-bags 2 and anchoring devices 1. The eco-bags 2 are neatly arranged on the slope, and then the anchoring devices 1 anchor the eco-bags 2 one by one on the slope.

[0033] like Figure 1 and Figure 4 As shown, the anchoring device 1 includes an anchor head 11, a push cylinder 12, a connecting rope 13 and a clamping assembly 14. The anchor head 11 is an inverted cone, and the anchor head 11 can pass through the push cylinder 12, and the anchor head 11 is against the bottom end of the push cylinder 12. The anchor head 11 is connected to the bottom end of the connecting rope 13, and the middle part of the connecting rope 13 is connected to the push cylinder 12 through the clamping assembly 14. When in use, the anchor head 11 is inserted into the eco-bag 2 and the ground through the push cylinder 12, and finally the push cylinder 12 is pulled out, so that the anchor head 11 remains below the ground, and then the eco-bag 2 is fixed by the connecting rope 13.

[0034] like Figure 5 As shown, the anchor head 11 has at least two circumferentially evenly distributed barbed pieces 111 (two are shown in the figure) hinged on the top of the anchor head 11, a tension spring is installed between the barbed piece 111 and the anchor head 11 for making the barbed piece 111 have a tendency to rotate outward and unfold, an abutment portion 112 is provided on the inner side of the barb portion close to one end of the anchor head 11, the top of the anchor head 11 is higher than the top of the abutment portion 112, when the barb piece 111 is in a retracted state, on the upward projection plane, the projection of the barb piece 111 is located within the projection area of ​​the anchor head 11, and when the barb piece 111 is in an expanded state, on the upward projection plane, the projections of the barb piece 111 and the abutment portion 112 exceed the projection area of ​​the anchor head 11.

[0035] like Figure 3 and Figure 4 As shown, the connecting rope 13 is made of synthetic materials such as polypropylene (PP) or polyester (PET), preferably a material with a degradation cycle similar to that of the eco-bag 2. The connecting rope 13 includes a connecting component 133, a main rope 131 and two branch ropes 132. The bottom end of the main rope 131 is fixedly connected to the anchor head 11, and the two branch ropes 132 are formed by dividing the other end of the main rope 131 into two strands. When the anchor head 11 is drilled into the soil, the push cylinder 12 is pulled out, and the two branch ropes 132 are respectively connected to the branch ropes 132 on the two adjacent anchoring devices 1 through the connecting component 133, so that the eco-bag 2 is fixed on the slope through the main rope 131 and the branch ropes 132.

[0036] like Figure 3As shown, the connecting assembly 133 includes bolts and nuts, and the ends of the two branch ropes 132 away from the main rope 131 are respectively connected to the bolts and nuts, and the bolts or nuts on at least one branch rope 132 are rotatably connected thereto, thereby preventing the branch ropes 132 from being twisted or untwisted and affecting the connection effect when connected to other branch ropes 132.

[0037] like Figure 2 and Figure 3 As shown, in order to make the main rope 131 more firmly fixed under the ground, a plurality of barb rings 1311 are installed on the main rope 131, and a plurality of expansion strips 1312 inclined outwardly and upwardly are arranged along the circumference of the barb ring 1311. After the push cylinder 12 is pulled out, the expansion strips 1312 have a tendency to flip outward. When the main rope 131 receives an upward pulling force, the expansion strips 1312 flip outward to expand and diffuse to the surrounding soil, thereby making the barb ring 1311 better anchored in the soil.

[0038] like Figure 2 and Figure 3 As shown, the clamping assembly 14 includes a sliding ring 141 arranged at the connection between the main rope 131 and the branch rope 132. The sliding ring 141 is slidably matched with the push cylinder 12. Two upwardly inclined elastic sheets 142 are symmetrically arranged on the sliding ring 141. Two clamping holes 12a that match the elastic sheets 142 are symmetrically opened on the wall of the push cylinder 12. When the elastic sheet 142 moves downward, the elastic sheet 142 passes through the inner side of the clamping hole 12a. When the elastic sheet 142 moves upward, the top of the elastic sheet 142 enters the clamping hole 12a. Continuing to move upward, the elastic sheet 142 gradually flattens, so that the sliding ring 141 is clamped at the position of the clamping hole 12a. At this time, the bottom end of the push cylinder 12 abuts against the abutment portion 112.

[0039] like Figure 2 , Figure 6 and Figure 7 As shown, the push cylinder 12 includes an elastic reset member 1223, a cylinder body 121 and a cylinder cap 122. The inner diameters of the cylinder body 121 and the cylinder cap 122 are slightly larger than the anchor head 11. The top of the cylinder body 121 is provided with a sliding groove 121a, and the bottom of the cylinder cap 122 is provided with a guide block 1221 that slides with the sliding groove 121a. The bottom end of the guide block 1221 is provided with a cutting portion 1222. The through hole formed between the cutting portion 1222 and the sliding groove 121a The hole is a card hole 12a, and the elastic reset member 1223 is preferably a spring sheet. The elastic reset member 1223 is installed between the cylinder body 121 and the cylinder cap 122, and is used to keep the card hole 12a at a size that allows the elastic sheet 142 to pass through. When the anchoring device 1 is inserted into the ecological bag 2 and the soil, the cylinder cap 122 is compressed to cause the cutting part 1222 to slide in the sliding groove 121a, thereby cutting off the elastic sheet 142, thereby avoiding the anchor head 11 from being pulled out when the sleeve is pulled out after the anchoring is completed.

[0040] like Figure 1 and Figure 7 As shown, a connection structure 1224 cooperating with a pile driving device is provided on the top of the barrel cap 122. The pile driving device is connected to the barrel cap 122, so that the anchoring device 1 is pressed into the slope as a whole. In order to prevent the pile driving device from pressing the support rope 132 and causing damage to the support rope 132, two clearance grooves for the support rope 132 to pass through are symmetrically provided on the top of the barrel cap 122.

[0041] Working principle: first place a row of eco-bags 2 at the bottom of the slope, then insert the anchor head 11 from the top of the tube cap 122, and the two barbed pieces 111 will shrink inward after contacting the push tube 12, so that the anchor head 11 and the barbed pieces 111 will pass through the bottom of the tube body 121, and the barbed pieces 111 will unfold under the action of the tension spring after passing through the push tube 12, and then the support rope 132 will be lifted upward, and the top of the elastic piece 142 will enter the clamping hole 12a and gradually flatten, so that the sliding ring 141 will be clamped with the push tube 12, and the support rope 132 cannot be lifted further, and at the same time, the bottom end of the tube body 121 will abut against the abutment 112, and because the top of the anchor head 11 is higher than the top of the abutment 112, the inner wall of the bottom of the tube body 121 will contact the top of the anchor head 11 , thereby avoiding the misalignment of the anchor head 11 and the cylinder body 121, and then installing the cylinder cap 122 on the piling device, and using the piling device to apply pressure to the cylinder cap 122. The cylinder cap 122 is pressed to make the cutting portion 1222 slide in the sliding groove 121a, thereby cutting off the elastic sheet 142, and at the same time, the anchor head 11 passes through the eco-bag 2 and is pressed below the ground, and then the push cylinder 12 is pulled out, and the two support ropes 132 are respectively connected to the support ropes 132 on the two adjacent anchoring devices 1 by bolts and nuts, and then repeating this process to lay the eco-bag 2 from bottom to top and anchor it on the slope. In this arrangement, only the anchor head 11 is made of steel, so the cost is greatly reduced, and at the same time, a row of eco-bags 2 are blocked by the support ropes 132, so the fixing effect of the eco-bag 2 is better.

[0042] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
