[0039] The following will detail the specific embodiments of the present utility model with reference to the drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present utility model and are not used to limit the present utility model.

[0040] An embodiment of the first aspect of the present utility model provides a passive protection structure for a roadbed slope, as Figure 1 and Figure 2 shown, which includes a lower pile foundation assembly 1, an upper clamping assembly 2, a support rod 3, and a protection net 4. The lower pile foundation assembly 1 is used to sleeve the bottom of the tree 5, and the lower pile foundation assembly 1 is connected to the bottom of the protection net 4. The upper clamping assembly 2 is located above the lower pile foundation assembly 1 and is used to be installed on the trunk of the tree 5. The upper clamping assembly 2 is connected to the top of the protection net 4. The support rod 3 is detachably connected between the upper clamping assembly 2 and the lower pile foundation assembly 1.

[0041] During use, as Figure 1 shown, when the tree 5 is in the sapling state, the lower pile foundation assembly 1 is sleeved on the bottom of the tree 5, and then a pit is dug at the position where the protection net support is erected, as Figure 2As shown, after placing the pile foundation assembly 1 in the pit, the soil is backfilled; subsequently, the clamping assembly 2 is installed on the trunk of the sapling, and the upper clamping assembly 2 clamps on the trunk; subsequently, the bottom of the protective net 4 is connected to the lower pile foundation assembly 1, and the top of the protective net 4 is connected to the upper clamping assembly 2 to complete the preliminary installation. As the sapling grows, the sapling will drive the upper clamping assembly 2 to rise, and the protective net 4 will be pulled up. When the required height of the protective net 4 is reached, a support rod 3 is connected between the upper clamping assembly 2 and the lower pile foundation assembly 1 to limit the distance between the upper clamping assembly 2 and the lower pile foundation assembly 1 and prevent the upper clamping assembly 2 from continuing to rise with the sapling.

[0042] Compared with the prior art, the passive protection structure for subgrade slopes provided by the embodiment of the first aspect of the present invention utilizes the tree body 5 as a natural support. The natural growth of the tree body 5 provides continuous support force, reduces the dependence on artificial column foundations, and solves the problems of difficult construction of traditional steel column foundations, narrow working space, and poor construction quality. It not only simplifies the construction process but also improves the stability and durability of the structure, is particularly suitable for areas with narrow working spaces such as mountain slopes, and improves the service life and durability of the protective net.

[0043] In an alternative embodiment, as Figure 2 and Figure 3 shown, the lower pile foundation assembly 1 includes a sleeve 11, a root pile cylinder 12, and a lower connecting member 13, where:

[0044] The sleeve 11 is sleeved outside the bottom of the tree body 5;

[0045] The lower connecting member 13 is connected to the top end of the sleeve 11, the bottom end of the protective net 4 is connected to the lower connecting member 13, and the bottom of the support rod 3 is detachably connected to the lower connecting member 13. The lower connecting member 13 plays a role in supporting the protective net 4 and the support rod 3;

[0046] The root pile cylinder 12 is buried underground and one end is communicated with the bottom of the sleeve 11.

[0047] During use, the sleeve 11 is sleeved outside the bottom of the tree body 5. Since one end of the root pile cylinder 12 is communicated with the bottom of the sleeve 11, the root hairs of the tree body 5 can extend from the sleeve 11 into the root pile cylinder 12, increasing the cooperation area between the lower pile foundation assembly 1 and the tree body 5. And since the root pile cylinder 12 is buried underground, the stability of the position of the lower pile foundation assembly 1 can be ensured when the tree body 5 is in the sapling stage.

[0048] In an alternative embodiment, as Figure 2 and Figure 3As shown, the sleeve 11 includes an upper cylinder 111 and a lower cylinder 112 connected to the upper cylinder 111. The upper cylinder 111 is radially convex with a boss 1111, and the bottom surface of the boss 1111 abuts against the ground. The lower connector 13 is connected to the upper cylinder 111, and the lower cylinder 112 is buried underground. One end of the root pile cylinder 12 communicates with the lower cylinder 112.

[0049] In the above embodiment, the lower cylinder 112 is buried underground and the bottom surface of the boss 1111 on the upper cylinder 111 abuts against the ground, so that the lower cylinder 112 and the boss 1111 can stabilize the position of the root pile cylinder 12 and prevent the root pile cylinder 12 from tilting.

[0050] It should be noted that, as Figure 2 shown, in order to enable the upper cylinder 111 to adapt to the growing tree body 5, there is a certain growth space between the inner wall of the upper cylinder 111 and the tree body 5 in the sapling stage. Similarly, the size of the lower cylinder 112 is also larger than the size of the root of the tree body 5 in the sapling stage.

[0051] The upper cylinder 111 can have an integral structure with the lower cylinder 112, or the upper cylinder 111 can be detachably connected to the lower cylinder 112.

[0052] In an alternative embodiment, the upper cylinder 111 can include a left cylinder and a right cylinder arranged oppositely. An accommodation cavity for the tree body 5 to pass through is formed between the left cylinder and the right cylinder. The positions of the left cylinder and the right cylinder relative to the lower cylinder 112 are adjustable along the radial direction of the tree body 5, so that the size of the accommodation cavity can increase as the tree body 5 grows.

[0053] Both the left cylinder and the right cylinder can be connected to the lower cylinder 112 by bolts and nuts. The lower cylinder is provided with kidney-shaped through slots for the bolts to pass through, and the kidney-shaped through slots extend along the radial direction of the tree body 5. When the positions of the left cylinder and the right cylinder need to be adjusted, the nuts on the bolts can be loosened. After the positions of the left cylinder and the right cylinder are adjusted, the nuts on the bolts can be tightened.

[0054] In an alternative embodiment, as Figure 3 shown, a plurality of root pile cylinders 12 are configured, and the plurality of root pile cylinders 12 are evenly distributed around the axis of the lower cylinder 112, so that the root pile cylinders 12 can fully accommodate the root hairs extending from the tree body 5 in all directions.

[0055] In an alternative embodiment, as Figure 2 shown, each root pile cylinder 12 bends and extends, and the bending direction of each root pile cylinder 12 is obliquely downward to better adapt to the extension direction of the root hairs.

[0056] In an alternative embodiment, the top end of the root pile cylinder 12 communicates with the lower cylinder 112, and the bottom end of the root pile cylinder 12 has an opening for the rootlets to extend out, so that during the growth of the tree body 5, the rootlets can extend out from the opening and thus extend into the soil outside the root pile cylinder 12, making the tree body 5 have a stronger grip force.

[0057] To further increase the stability of the tree body 5 relative to the lower pile foundation assembly 1, the root pile cylinder 12 is filled with soil, and the rootlets of the tree body 5 are planted in the soil, so that the tree body 5 forms a tight connection with the root pile cylinder 12.

[0058] In an alternative embodiment, as Figure 1 shown, the lower connecting member 13 is configured with a plurality of connecting positions 131, and the plurality of connecting positions 131 are evenly distributed around the axis of the sleeve 11, where:

[0059] In each connecting position 131, either the protective net 4 or the support rod 3 can be connected, and at least one connecting position 131 is connected to the bottom of the protective net 4, and at least one connecting position 131 is detachably connected to the bottom of the support rod 3.

[0060] In the above embodiment, the connecting position 131 connected to the protective net 4 can limit the protective net 4, and the connecting position 131 connected to the support rod 3 can limit the support rod 3.

[0061] In an alternative embodiment, the lower connecting member 13 includes a plurality of arc-shaped connecting rings, and the plurality of arc-shaped connecting rings are arranged in sequence along the circumference of the upper cylinder 111, and a connecting position 131 is formed between the ends of every two adjacent connecting rings.

[0062] Each arc-shaped connecting ring can be fixedly connected to the outer surface of the upper cylinder 111, or the ends of every two adjacent connecting rings can be fixedly connected, and the lower connecting member 13 is sleeved tightly outside the upper cylinder 111.

[0063] The above connecting position 131 can be annular, or can be hook-shaped, etc.

[0064] In an alternative embodiment, as Figure 4 shown, the upper clamping assembly 2 includes a clamping seat 21, an elastic member 22 and an upper connecting member 23, where:

[0065] The clamping seats 21 are configured to be a plurality of spaced around the tree trunk, and any two adjacent clamping seats 21 are connected by an elastic member 22;

[0066] On the side of each clamping seat 21 facing away from the tree trunk, an upper connecting member 23 is connected, and each upper connecting member 23 is connected to one of the protective net 4 and the support rod 3, and at least one upper connecting member 23 is connected to the top of the protective net 4, and at least one upper connecting member 23 is detachably connected to the top of the support rod 3.

[0067] When in use, since any two adjacent clamping seats 21 are connected by an elastic member 22, the distance between two adjacent clamping seats 21 can be changed following the growth of the tree body 5, adapting to the change in the radial dimension of the tree body 5.

[0068] The number of the upper connecting members 23 can be consistent with the number of the connecting positions 131, and each of the upper connecting members 23 and each of the connecting positions 131 are arranged opposite to each other in the vertical direction. A protective net 4 can be connected between a pair or several pairs of the relatively arranged upper connecting members 23 and connecting positions 131, and a support rod 3 can be connected between another pair or several pairs of the relatively arranged upper connecting members 23 and connecting positions 131.

[0069] Among them, the elastic member 22 can be a spring, and the end of the spring can be connected with the clamping seat 21 by welding, clamping or other means.

[0070] In addition, the upper connecting member 23 can be connected with the clamping seat 21 by screws, clamping or other means, and the upper connecting member 23 can include a connecting ring, a connecting hook or the like.

[0071] In an alternative embodiment, as Figure 4 and Figure 5 shown, the clamping seat 21 includes a middle block 211, a clamping plate 212 and a sliding plate 213, wherein:

[0072] The middle blocks 211 between two adjacent clamping seats 21 are connected by an elastic member 22, and one upper connecting member 23 is connected to the side of each middle block 211 facing away from the tree trunk;

[0073] One of the clamping plate 212 and the sliding plate 213 is detachably connected to the side of each middle block 211 facing the tree trunk. The surface of the clamping plate 212 facing the tree trunk has a tooth-shaped structure, and the sliding plate 213 is in rolling cooperation with the tree trunk.

[0074] The clamping plate 212 and the sliding plate 213 can be detachably connected to the middle block 211 by screws or clamping.

[0075] After the pile foundation assembly 1 is placed in the dug pit and the soil is backfilled, the clamping assembly 2 is sleeved on the top of the sapling. At this time, the sliding plate 213 is not used in the upper clamping assembly 2. In the upper clamping assembly 2 at this time, the middle block 211 is connected to the clamping plate 212 by a bolt member 214, and the clamping plate 212 contacts the tree body 5 through the tooth-shaped structure, and the upper clamping assembly 2 is fixed on the tree body 5 through the tooth-shaped structure. Then, the connecting cable at the bottom of the protective net 4 is connected to a suitable connecting position 131, and the connecting cable at the top of the protective net 4 is connected to a suitable upper connecting member 23, as Figure 4 shown, and the preliminary installation is completed.

[0076] As the tree body 5 grows, the tree body 5 will drive the upper clamping component 2 clamped thereon to move upward. Due to the action of the elastic member 22, while the tree body 5 grows taller, the elastic member 22 can stretch to adapt to the diameter of the tree body 5. As the tree body 5 grows, the protective net 4 will be pulled up. When the required height of the protective net 4 is reached, that is, when the connecting cable at the top of the protective net 4 is 5 m away from the ground, the middle block 211 is pulled in a direction away from the tree body 5. As the middle block 211 is pulled, the clamping plate 212 will disengage from the contact with the tree body 5. The bolt member 214 is removed, and the clamping plate 212 and the middle block 211 are separated. Subsequently, the sliding plate 213 is placed at the original position of the clamping plate 212, and the middle block 211 is connected to the sliding plate 213 through the bolt member 214 to complete the installation between the sliding plate 213 and the middle block 211. Subsequently, as Figure 6 shown, a support rod 3 is connected between the connection position 131 where the protective net 4 is not connected and the upper connecting member 23. The support rod 3 is used to support the structure of the upper clamping component 2 to prevent the upper clamping component 2 from slipping off the surface of the tree body 5. At this time, as the tree body 5 continues to grow, the elastic member 22 adapts to the growth of the width of the tree body 5, and the tree body 5 is in rolling contact with the sliding plate 213. The growth of the height of the tree body 5 will no longer drive the upper clamping component 2 to move in position, and the passive protection structure of the roadbed slope is in a full protection state.

[0077] In an alternative embodiment, as Figure 5 shown, the sliding plate 213 includes a strip plate 2131 and a pulley member 2132. The strip plate 2131 can be detachably connected to the side of the middle block 211 facing the tree trunk by screws or snap connection. Pulley members 2132 are connected to both the top and the bottom of the strip plate 2131, and the pulley members 2132 are in rolling cooperation with the tree trunk.

[0078] The structure of the above-mentioned sliding plate 213 is simple and can effectively prevent the tree body 5 from driving the upper clamping component 2 to move upward during the growth process.

[0079] Among them, the pulley member 2132 can include a connecting rod and rollers rotatably connected to both ends of the connecting rod.

[0080] A support rod 3 is connected between the connection position 131 and the upper connecting member 23 arranged oppositely up and down. As Figure 5 shown, in an alternative embodiment, the support rod 3 can include a first rod body and a second rod body arranged oppositely. The tops of the first rod body and the second rod body are jointly detachably connected to the upper connecting member 23, and the tops of the first rod body and the second rod body are jointly detachably connected to the connection position 131.

[0081] Specifically, the first rod body and the second rod body can be detachably connected to the connection position 131 and the upper connecting member 23 through connection methods such as snap connection and screw connection.

[0082] In the second aspect of the present utility model, an embodiment lies in providing a passive protection system for a subgrade slope. The passive protection system for a subgrade slope provided by the embodiment of the second aspect of the present utility model includes a tree body 5 and the above-mentioned passive protection structure for a subgrade slope. The lower pile foundation assembly 1 is sleeved on the bottom of the tree body 5, and the upper clamping assembly 2 is installed on the trunk of the tree body 5.

[0083] The passive protection system for a subgrade slope provided by the second aspect of the present utility model has the passive protection structure for a subgrade slope provided by the embodiment of the first aspect of the present utility model, and thus has all the beneficial effects of the passive protection structure for a subgrade slope provided by the embodiment of the first aspect of the present utility model.

[0084] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
