Description

Technical Field

[0001] This application relates to the technical field of landscaping, and particularly to a biological hedge cofferdam with the functions of soil and water conservation and tree support. Background Art

[0002] After transplanting arbors on slopes, the soil around the arbors is relatively loose, which is prone to soil and water loss and poor stability of the transplanted arbors. The existing cofferdams for transplanted tree holes on slopes mainly have the following defects: the stability of the cofferdams is insufficient. In case of heavy rain or continuous rainy days, the water accumulated in the holes is likely to wash away the cofferdams, resulting in more serious scouring at the bottom of the slopes, further leading to more serious soil and water loss, and prone to the adverse situation of the transplanted arbors toppling. Therefore, further improvement is needed. Content of the Utility Model

[0003] In order to intercept rainwater runoff and maintain the soil and water around the arbors, this application provides a biological hedge cofferdam with the functions of soil and water conservation and tree support.

[0004] A biological hedge cofferdam with the functions of soil and water conservation and tree support provided by this application adopts the following technical solutions:

[0005] A biological hedge cofferdam with the functions of soil and water conservation and tree support includes a gabion box arranged at the lower side of an arbor on a slope, a growth substrate layer laid in the gabion box, a plant hedge planted in the growth substrate layer, and at least two pile nails vertically penetrating through the gabion box and nailed on the slope. A support mechanism is arranged between the pile nails and the arbor trunk. The support mechanism includes a support arm, a pair of hinge seats respectively hinged at both ends of the support arm, and a hoop arranged on the hinge seats to clamp and fix the pile nails / arbor trunk.

[0006] By adopting the above technical solutions, the growth substrate layer provides nutrients for the plant hedge. The gabion box is fixed to the slope through the pile nails, effectively reducing the possibility of landslides of the biological hedge cofferdam. The gabion box locks the growth substrate layer. The mechanical blocking effects of the gabion box and the plant hedge can effectively maintain the soil and water around the arbor. Moreover, the pile nails and the arbor trunk are combined into a whole through the support mechanism, which can play a role in supporting and stabilizing the transplanted arbor. The hoop is connected to the end of the support arm through the hinge seat, so that the hoop stably clamps and fixes the pile nails / arbor trunk. The length direction of the support arm is parallel to the slope, shortening the size of the pile nails.

[0007] Preferably, the support arm is a telescopic arm.

[0008] By adopting the above technical solutions, the support arm is arranged in a telescopic arm structure, and the length of the support arm can be adjusted according to the distance between the pile nails and the arbor trunk, so that the hoop clamps and fixes the pile nails / arbor trunk.

[0009] Preferably, the support arm includes a support pipe and a support rod slidably inserted into the support pipe. The two hinge seats are respectively hinged to the ends of the support pipe and the support rod, and the support pipe is provided with an adjusting member for adjusting the sliding position of the support rod.

[0010] By adopting the above technical solution, the relative sliding of the support rod with respect to the support pipe is adjusted by the adjusting member, so as to adjust the length dimension of the support arm, enabling the clamps provided at both ends of the support arm to smoothly clamp and fix to the pile nails / arbor trunks.

[0011] Preferably, the support rod is a screw rod, and the adjusting member is a screw sleeve coaxially and rotatably connected to the end of the support pipe, and the screw sleeve is threadedly sleeved on the screw rod.

[0012] By adopting the above technical solution, when the screw sleeve is rotated, the support rod is restricted by the threads of the screw sleeve and slides axially along the support pipe, realizing the adjustment of the length of the support arm.

[0013] Preferably, a limiting ring groove is circumferentially formed in the upper part of the pile nail, and the limiting ring groove is located above the gabion box. The clamping plate of the clamp abuts against the inner wall of the limiting ring groove.

[0014] By adopting the above technical solution, the addition of the limiting ring groove enables the clamp to be clamped in the limiting ring groove, effectively reducing the possibility of the clamp sliding axially along the pile nail, thereby reducing the possibility of the clamp coming off the pile nail.

[0015] Preferably, a reinforcing rod is fixedly connected between the two pile nails.

[0016] By adopting the above technical solution, the addition of the reinforcing rod connects the two pile nails into a whole, effectively improving the structural stability of the pile nails.

[0017] Preferably, a first through hole is formed through the upper part of the pile nail, a second through hole is formed in the clamping piece of the clamp, the reinforcing rod is a screw rod, the reinforcing rod passes through the first through hole and the second through hole, and the reinforcing rod is threadedly connected to a locking nut abutting against the outer side wall of the clamping piece of the clamp.

[0018] By adopting the above technical solution, the reinforcing rod passes through the first through hole and the second through hole, enabling the clamp clamped to the pile nail and the pile nail to be connected into a whole, reducing the possibility of the clamp coming off the pile nail.

[0019] Preferably, the reinforcing rod has a liquid flow channel, drip holes communicating with the liquid flow channel are formed in the outer peripheral wall of the reinforcing rod, and the reinforcing rod is externally connected to a water delivery pipe.

[0020] By adopting the above technical solution, the water delivery pipe delivers water to the liquid flow channel in the reinforcing rod, and the water performs drip irrigation on the plant hedge in the gabion box through the drip holes, improving the growth rate of the plant hedge.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. The growth matrix layer provides nutrients for the plant hedge. The gabion box is fixed to the slope surface by pile nails, effectively reducing the possibility of landslides occurring in the biological hedge cofferdam. The gabion box locks the growth matrix layer. The mechanical blocking effects of the gabion box and the plant hedge can effectively retain the soil and water around the arbor. Moreover, the pile nails and the arbor trunk are combined into a whole through the support mechanism, which can play a role in supporting and stabilizing the transplanted arbor. The hoop is connected to the end of the support arm through the hinge seat, so that the hoop stably clamps and fixes the pile nail / arbor trunk. The length direction of the support arm is parallel to the slope surface, shortening the size of the pile nails;

[0023] 2. The support arm is arranged as a telescopic arm structure, and the length of the support arm can be adjusted according to the distance between the pile nail and the arbor trunk, so that the hoop clamps and fixes the pile nail / arbor trunk;

[0024] 3. A limiting ring groove is added, so that the hoop is clamped in the limiting ring groove, effectively reducing the possibility of the hoop sliding along the axial direction of the pile nail, thereby reducing the possibility of the hoop coming off the pile nail.
