Description

Technical Field

[0001] This invention relates to the field of slope ecological management technology, specifically to a construction method for a multi-tube self-expanding filling vegetation device. Background Technology

[0002] Construction work damages the surface structure and vegetation, and causes more severe disturbance to the slope ecosystem, exacerbating soil erosion. Excavation destroys the original vegetation layer of the slope, causing the slope rock to break up, and also causes a series of ecological and environmental problems, such as soil erosion, debris flow, landslides and loss of the food chain.

[0003] Water-swellable rubber (i.e., water-swellable rubber) can absorb water and swell when it comes into contact with water. Its expansion degree can reach hundreds of times, and it still retains elasticity and strength after expansion, playing a role in filling pores.

[0004] Repairing depressions and pits on excavated slopes is often a complex and costly process using conventional methods. This is especially true when filling and greening depressions and pits on slopes where water diversion is difficult, making rapid and efficient completion of the work extremely challenging. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a construction method for a multi-tube self-expanding filling vegetation device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this invention is: a construction method for a multi-tube self-expanding filling vegetation device, which includes the following steps:

[0007] S1: Insert the solid nail head at the bottom of the hollow anchor at the bottom of the lower section into the bottom of the depression in the slope and compact it to fix the entire structure in the depression in the slope.

[0008] S2: Pull out the pin set in the limiting hole, pull the upper push rod upward, so that the piston at the bottom of the upper push rod moves upward relative to the lower hollow anchor. Due to the negative pressure adsorption, the water in the water bag is sucked into the hollow cavity inside the lower hollow anchor through the one-way water inlet. Pull the upper push rod up to the predetermined position so that enough water flows into the lower hollow anchor.

[0009] S3: Push the upper push-pull rod downwards, causing the piston at the bottom of the upper push-pull rod to move downwards, squeezing the water between the piston and the baffle until the baffle cannot withstand the pressure and breaks, allowing the water to flow into the expansion layer through the water outlet hole on the side wall of the lower hollow anchor. After the upper push-pull rod moves to the corresponding position, insert a pin between the corresponding other set of limiting holes to fix the relative position between the lower hollow anchor and the upper push-pull rod.

[0010] S4: The water-swelling rubber material in the self-expanding layer absorbs water and expands, thereby pushing the entire water bag and the planting groove to move upward, and stopping when the planting groove moves to contact the limiting disc at the top of the upper section push-pull rod. The above movement process causes the entire self-expanding layer, water bag and planting groove to quickly fill the slope concave pits;

[0011] S5: When the water-swelling rubber material in the self-expanding layer continues to expand, the water bag is squeezed by the top of the self-expanding layer and the bottom of the planting groove because the planting groove is limited by the limiting disc, and the spikes at the bottom of the planting groove pierce the top of the water bag, thereby connecting the water guide strip in the spikes with the inside of the water bag and the inside of the planting groove, and water enters the planting groove along the water guide strip, providing necessary water for the seed germination and growth in the planting groove.

[0012] Further, the multi-tube self-expanding filling planting device comprises a planting groove, a water bag and a self-expanding layer arranged in the slope concave pit from top to bottom, and a plurality of push-pull hollow anchor nails are vertically arranged in the planting groove, water bag and self-expanding layer. The push-pull hollow anchor nail comprises an upper section push-pull rod at the upper side and a lower section hollow anchor nail at the lower side, the bottom of the upper section push-pull rod is connected with a piston in the lower section hollow anchor nail, a water outlet hole is arranged in the sidewall of the lower section hollow anchor nail below the piston, a one-way water inlet hole is arranged in the sidewall of the lower section hollow anchor nail above the water outlet hole, the one-way water inlet hole is located in the inside of the water bag, the water outlet hole is located in the inside of the self-expanding layer, and a baffle is arranged on the inner wall of the lower section hollow anchor nail between the water outlet hole and the one-way water inlet hole.

[0013] Further, the planting groove is filled with plant seeds and planting medium, and the components of the planting medium are respectively 98-100 parts of soil, 5-6 parts of organic matter, 3-4 parts of ceramic granules and 5-6 parts of vermiculite.

[0014] Further, the bottom of the planting groove is provided with spikes, the spikes are hollow structures, the inside of the spikes is provided with a water guide strip, the water guide strip is a cotton strip structure, penetrates through the entire spike, and the top of the water guide strip extends into the planting medium in the planting groove.

[0015] Further, the inside of the self-expanding layer is filled with water-swelling rubber material, and the outside of the self-expanding layer is wrapped with a packaging bag.

[0016] Further, the top of the upper section push-pull rod is provided with a limiting disc.

[0017] Further, the surface of the upper section push-pull rod and the surface of the lower section hollow anchor nail are both provided with limiting holes, and the limiting holes are matched with the bolt.

[0018] Further, the baffle is a plastic film structure, and a one-way valve is arranged in the one-way water inlet hole.

[0019] Further, the bottom of the lower hollow anchor is also provided with a solid nail head.

[0020] The present application has the following advantages:

[0021] 1. The multi-tube self-expanding filling and planting device has simple structure, only five parts of planting groove, water bag, upper segment push-pull rod, lower hollow anchor and self-expanding layer, less construction steps, easy to complete, can quickly fill the slope concave pit after construction, and independently complete the remaining filling and greening function, greatly reducing the cost of manpower and material resources; shorten the construction and maintenance time.

[0022] 2. The upper segment push-pull rod is pulled upwards first, so that the piston at the bottom of the upper segment push-pull rod moves upwards relative to the lower hollow anchor, and due to the negative pressure adsorption effect, the water in the water bag is sucked into the hollow cavity inside the lower hollow anchor through the one-way water inlet hole. The upper segment push-pull rod is pulled up to the predetermined position, so that enough water flows into the lower hollow anchor; then the upper segment push-pull rod is pushed downwards, so that the piston at the lower part of the upper segment push-pull rod moves downwards, and the water between the piston and the baffle is squeezed, until the baffle breaks under the pressure, and the water flows into the self-expanding layer through the water outlet hole in the side wall of the lower hollow anchor.

[0023] 3. The water-swelling rubber material in the self-expanding layer absorbs water and swells, thereby pushing the entire water bag and planting groove to move upwards, and when the planting groove moves to contact the limiting disc at the top of the upper segment push-pull rod, the movement stops. The above movement process makes the entire self-expanding layer, water bag and planting groove quickly fill the slope concave pit.

[0024] 4. In the process of expansion of the self-expanding layer, as its volume increases, and cooperates with the fixing effect of the upper segment push-pull rod, the water bag is squeezed, and the sharp spike at the bottom of the planting groove pierces the top of the water bag, so that the water guide strip in the sharp spike is connected with the inside of the water bag and the inside of the planting groove, and the water enters the planting groove along the water guide strip, providing necessary water for the seed germination and growth in the planting groove.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0034] like Figures 1 to 8 As shown, a multi-tube self-expanding filling vegetation device includes a vegetation trough 2, a water bag 3, and a self-expanding layer 4 arranged from top to bottom within a depression 1 on a slope. Multiple push-pull hollow anchors 5 are vertically inserted into the vegetation trough 2, water bag 3, and self-expanding layer 4. Each push-pull hollow anchor 5 includes an upper push-pull rod 5.1 located on the upper side and a lower hollow anchor 5.2 located on the lower side. The bottom of the upper push-pull rod 5.1 is connected to the lower hollow anchor 5.2. A piston 5.3 is connected. A water outlet hole 5.4 is provided on the side wall of the lower hollow anchor 5.2 below the piston 5.3. A one-way water inlet hole 5.5 is provided on the side wall of the lower hollow anchor 5.2 above the water outlet hole 5.4. The one-way water inlet hole 5.5 is located inside the water bag 3. The water outlet hole 5.4 is located inside the self-expanding layer 4. A baffle plate 5.6 is provided on the inner wall of the lower hollow anchor 5.2 between the water outlet hole 5.4 and the one-way water inlet hole 5.5.

[0035] Preferably, the vegetation trough 2 is filled with plant seeds and vegetation substrate, and the components of the vegetation substrate are as follows by weight: 98-100 parts soil, 5-6 parts organic matter, 3-4 parts ceramsite, and 5-6 parts vermiculite.

[0036] Preferably, the bottom of the planting trough 2 is provided with a spike 2.1, which is a hollow structure. Inside the spike 2.1 is a water guide strip 2.2, which is a long cotton strip that runs through the entire spike 2.1 and extends into the planting substrate inside the planting trough 2. By setting the water guide strip 2.2, water from the water bag 3 can be introduced into the planting trough 2 after the spike 2.1 punctures the water bag 3, providing the necessary moisture for seed germination and growth in the planting trough 2.

[0037] Preferably, the self-expanding layer 4 is filled with water-swellable rubber material inside and wrapped with a packaging bag outside. The water-swellable rubber material inside the self-expanding layer 4 will react and swell when absorbing water, so as to quickly fill the entire slope pit 1.

[0038] Preferably, the upper section push-pull rod 5.1 is provided with a limiting disc 5.7 at the top. When the self-expanding layer 4 expands and drives the entire planting groove 2 to rise, the limiting disc 5.7 can limit the planting groove 2. Generally, the position of the limiting disc 5.7 is flush with the top of the slope pit 1, which can prevent the planting groove 2 from protruding from the slope pit 1. In addition, during the subsequent expansion of the self-expanding layer 4, the planting groove 2 is stopped by the limiting disc 5.7, and the water bag 3 is reversely extruded by the bottom of the planting groove 2, so that the spikes 2.1 at the bottom of the planting groove 2 can pierce the top of the water bag 3.

[0039] Preferably, the surface of the upper section push-pull rod 5.1 and the surface of the lower section hollow anchor nail 5.2 are both provided with limiting holes 5.8, which are matched with the bolt. Through the cooperation of the limiting holes 5.8 and the bolt, the relative position of the upper section push-pull rod 5.1 and the lower section hollow anchor nail 5.2 can be fixed.

[0040] Preferably, the baffle 5.6 is a plastic film structure, and a one-way valve is arranged in the one-way water inlet hole 5.5. After the one-way valve is arranged in the water inlet hole 5.5, the water in the water bag 3 can only enter the lower section hollow anchor nail 5.2 through the one-way water inlet hole 5.5. This one-way passing property ensures that when the water between the piston 5.3 and the baffle 5.6 is pushed down by the subsequent piston, the water will not flow out of the one-way water inlet hole 5.5. The baffle 5.6 has two functions here. First, the space below the baffle 5.6 and the lower section hollow anchor nail 5.2 is isolated, which can prevent the water from flowing into the lower section hollow anchor nail 5.2 through the one-way water inlet hole 5.5 due to the air leakage of the water outlet hole 5.4 of the lower section hollow anchor nail 5.2 when the piston 5.3 is lifted to suck the water in the water bag 3, so as to ensure the air tightness. Second, since the baffle 5.6 is a plastic film, when the piston 5.3 is lowered, the water flow will not flow out of the one-way water inlet hole 5.5. In this way, the baffle 5.6 is easily broken under the action of water pressure, so as to be discharged through the water outlet hole 5.4 of the lower section hollow anchor nail 5.2.

[0041] Preferably, the bottom of the lower section hollow anchor nail 5.2 is also provided with a solid nail head 5.9. The solid nail head 5.9 is convenient for insertion into the bottom of the slope pit 1 and compaction, so as to fix the entire structure in the slope pit 1.

[0042] In addition, the construction method of the above-mentioned multi-tube self-expanding filling planting device is disclosed, which comprises the following steps:

[0043] S1: asFigure 5 As shown, the solid nail head 5.9 at the bottom of the hollow anchor nail 5.2 in the lower section is inserted into the bottom of the slope depression pit 1 and compacted, so that the entire structure is fixed in the slope depression pit 1.

[0044] S2: As Figure 6 As shown, pull out the pin set in the limiting hole 5.8, pull the upper push rod 5.1 upward, so that the piston 5.3 at the bottom of the upper push rod 5.1 moves upward relative to the lower hollow anchor 5.2. Due to the negative pressure adsorption effect, the water in the water bag 3 is sucked into the hollow cavity inside the lower hollow anchor 5.2 along the one-way water inlet hole 5.5. Pull the upper push rod 5.1 up to the predetermined position, so that enough water flows into the lower hollow anchor 5.2.

[0045] S3: As Figure 7 As shown, pushing the upper push-pull rod 5.1 downward causes the piston 5.3 at the lower part of the upper push-pull rod 5.1 to move downward, squeezing the water between the piston 5.3 and the baffle 5.6 until the baffle 5.6 can no longer withstand the pressure and breaks, allowing the water to flow into the expansion layer 4 through the water outlet 5.4 on the side wall of the lower hollow anchor 5.2. After the upper push-pull rod 5.1 moves to the corresponding position, a pin is inserted between the corresponding other set of limiting holes 5.8 to fix the relative position between the lower hollow anchor 5.2 and the upper push-pull rod 5.1.

[0046] S4: As Figure 8 As shown, the water-swellable rubber material in the self-expanding layer 4 absorbs water and expands, thereby pushing the entire water bag 3 and the vegetation trough 2 to move upward. When the vegetation trough 2 moves to the limit disc 5.7 at the top of the upper push-pull rod 5.1, it stops moving. The above-mentioned movement process makes the entire self-expanding layer 4, water bag 3 and vegetation trough 2 quickly fill the depression pit 1 on the slope.

[0047] S5: As the water-swellable rubber material in the self-expanding layer 4 continues to expand, the planting trough 2 stops moving due to the limiting disc 5.7. Therefore, the water bag 3 is subjected to the squeezing force from the top of the self-expanding layer 4 and the bottom of the planting trough 2. The spikes 2.1 at the bottom of the planting trough 2 pierce the top of the water bag 3, thereby allowing the water guide strip 2.2 inside the spikes 2.1 to connect the inside of the water bag 3 and the inside of the planting trough 2. Water enters the planting trough 2 along the water guide strip 2.2, providing the necessary water for the germination and growth of the seeds in the planting trough 2.

The embodiments in the present application and the features in the embodiments can be combined with each other as long as there is no conflict. The protection scope of the present application should be based on the technical solutions described in the claims and include equivalent replacement solutions of the technical features described in the claims.
