TECHNICAL FIELD

[0001] The present application relates to the technical field of bank slope repair, in particular to a self-complementing and self-irrigating device for high and steep expansive soil slopes and an application method thereof. BACKGROUND

[0002] Expansive soil is a regional special soil rich in mineral components such as kaolinite, montmorillonite and illite, and has strong water sensitivity and swelling-shrinking properties, and is very sensitive to environmental heat and humidity changes. The swelling and shrinking of expansive soil will repeatedly occur due to the influence of the natural environment. Since the loss of expansive soil to engineering is common in engineering construction, expansive soil is known as the "cancer" in engineering. To ensure the safety and stability of related engineering, how to reinforce high and steep expansive soil slopes and effectively prevent water and soil loss has become a big problem.

[0003] The defects of the existing ecological slope protection structure are:

[0004] 1. The document CN220166953U discloses an ecological toughness lattice anchoring structure for protecting expansive soil slopes, and the protected item is "including a vegetation protection pad, a lattice beam, an anchor rod, a U-shaped nail, a water interception and drainage ditch, and slope vegetation. The vegetation protection pad is laid from the slope toe to the rear edge of the slope top of the expansive soil slope and is in close contact with the soil body. The side and bottom edges of the vegetation protection pad are embedded in the bottom of the drainage ditch, the top edge passes through the bottom of the water interception ditch to the rear edge of the slope top and is fixed with the U-shaped nail. The lattice beam is arranged on the vegetation protection pad, and the anchor rod is arranged at the intersection of the longitudinal beam and the transverse beam of the lattice beam. The water interception and drainage ditch fixes the vegetation protection pad at the bottom, and the slope vegetation is densely planted in the lattice. The anchor rod, the vegetation protection pad, the lattice beam, the slope vegetation and the slope soil body are connected into a whole. The present utility model can realize surface protection and deep anti-sliding of steep expansive soil slopes, improve the overall stability of the slope, and has good long-term treatment effect." However, the structure lacks automatic irrigation function. In the early growth stage of the plants, water supplement needs to be ensured. The rainfall water supplement method has high uncertainty, and the slope after repair lacks personnel management, so an automatic irrigation structure is needed.

[0005] 2. The utility model discloses an expansive soil slope protection device, and the protected right item "including expansive soil slope, the expansive soil slope is laid with geotextile layer, coarse -grained soil layer, silt layer, vegetation layer and earthwork grid layer from inside to outside in proper order, a plurality of anchor rod structures are arranged on the earthwork grid layer and are spaced, and the anchor rod structure passes through earthwork grid layer intersection point, vegetation layer, silt layer, coarse -grained soil layer and geotextile layer in proper order, and its bottom is fixed with the expansive soil slope, the expansive soil slope top is provided with the water interception ditch, and the expansive soil slope bottom is provided with the drainage ditch, and the water interception ditch and the drainage ditch are communicated through a plurality of connecting pipelines. The utility model can effectively prevent water from seeping into the expansive soil slope, avoid the slope surface disintegration, make the expansive soil water content of slope body keep in a relatively balanced state, maintain the long -term stability of slope. The earthwork grid layer prevents the vegetation layer from being damaged by nature, guarantees the stable growth of vegetation. The anchor rod structure can adapt to the expansion and contraction of the expansive soil through the buffer sleeve, and make the anchor rod structure long -term effective. But its method process is more complicated and needs to pay a lot of manpower, and the time cost is also higher.

[0006] 3.

But its structure lacks the anti -scouring device, and the backfill layer is impacted by rainwater and leads to nutrient loss, which is not conducive to the growth of plants.

[0007] Traditional expansive soil slope reinforcement methods include slope pressing feet, slope protection, anti -slip piles, retaining walls, anchor rods (cables), soil nails, soil replacement backfilling, etc. However, these methods have problems such as high engineering cost, large engineering quantity, long construction period, difficult to guarantee quality, weak anti -scouring effect, and inability to provide stable water supply for plants on the slope. At the same time, high and steep expansive soil slopes are prone to geological disasters under the influence of rainfall, and the strong hydrophilicity of expansive soil leads to soil erosion, and plants are difficult to grow in the original soil. Therefore, it is urgent to invent a self -lighting and self -irrigation device for high and steep expansive soil slopes and a construction method to solve the above problems. SUMMARY

[0025] A method for applying a self-supplementing light and self-irrigating device to a high and steep expansive soil slope, the method for protecting the slope body using the self-supplementing light and self-irrigating device comprises the following steps:

[0026] Step one: clean the slope surface, use the removed floating soil to improve the gradation and reasonably mix additives, organic matter and microorganisms to make it suitable for plant growth, uniformly mix plant seeds in the improved soil and put them into the plant growth bag for subsequent use;

[0027] Step two: dig a water interception ditch 5 meters away from the outer edge of the slope top, set up a side ditch at the slope foot, tightly adhere the cement blanket and the degradable waterproof plastic film in the order of the cement blanket on top and the degradable waterproof plastic film below, fix one end of the two on the slope top and cover the water interception ditch, and let the other end down from the slope top to cover the slope;

[0028] Step three: butt the prefabricated plant growth box with the corresponding self-consolidation anchor rod, and drive the self-consolidation anchor rod into the predetermined position, so that the self-consolidation anchor rod penetrates through the cement blanket and the degradable waterproof plastic film, and when the self-consolidation anchor rod outside the circular ring-shaped position limiter compresses the plant growth box and the cement blanket, it reaches the predetermined depth, and the construction of the next self-consolidation anchor rod can be started until the self-consolidation anchor rod is installed according to the predetermined position;

[0029] Step four: use a screw to connect the plant growth box and the self-consolidation anchor rod outside the circular ring-shaped position limiter, so that the plant growth box and the self-consolidation anchor rod are connected into a whole, then push the automatic water supply rod into the self-consolidation anchor rod, so that the push type anchor head inside the self-consolidation anchor rod and the small anchor sharp cylinder are extruded into the slope body, in the process, when the small anchor sharp cylinder penetrates through the opening into the slope body, the cutter can cut the reaction strip in the small anchor sharp cylinder, so that the reaction material in the small anchor sharp cylinder contacts the soil to produce cementation, then insert the water supply pipe into the reserved butt joint of the water storage box at the bottom of the plant growth box, and finally put the plant growth bag into the plant growth box;

[0030] Step five: from the top of the slope, water curing, cement blanket hardening, the excess water along the slope structure into the vertical edge ditch, the water collected in the vertical edge ditch as the follow-up maintenance of water, the water purifying cover on the top of the planting box in the process of watering through activated carbon particles filter water and guide the automatic water supply rod, the automatic water supply rod after water replenishment through the siphon effect automatically water replenishment to the water storage box at the bottom of the planting box, the water storage box provides water to the inside of the planting box for plant seed germination, complete construction;

[0031] Step six: when it rains, the weight of the water purifying cover on the top of the planting box after absorbing water is greater than the force of the cover control box, then the water purifying cover rotates and falls and blocks the rainwater above the planting box, at this time the light supplementing plate is attached to the planting box by the pulling of the pulling rope;

[0032] When the rain stops, the water absorbed in the water purifying cover on the top of the planting box evaporates gradually, when the weight decreases to a certain critical value, the force in the cover control box is greater than the weight of the water purifying cover, so that the water purifying cover rises, at this time the light supplementing plate is opened under the action of its own weight;

[0033] Step seven: when it rains, part of the rainwater enters the automatic water supply rod after being filtered by the water purifying cover, the automatic water supply rod replenishes water, and then the water in the water storage box rises in the process of replenishment, pushes the floating block in the water storage box to float, so that it contacts the water blocking switch and closes the water supply pipe, so as to stop water supply.

[0034] The beneficial effects of the present application are:

[0035] 1. The automatic water supply rod of the present application can supply water to the water storage box through siphon effect, and the floating block inside the water storage box can control the start and stop of water replenishment; when there is water shortage, the floating block descends with the water level, the water blocking switch in the water storage box is opened, the automatic water supply rod supplies water to the water storage box, and with the water replenishment, the water level in the water storage box rises until the floating block closes the water blocking switch and stops water supply; the whole process can automatically replenish water for the water storage box, ensuring the normal growth of plants in the planting box;

[0036] 2. The water purification cover of the present application has the following effects: the water purification cover can filter rainwater and supplement part of the filtered rainwater to the automatic water supply rod as a reserve for subsequent plant growth; and the combination of the water purification cover, the cover plate control box and the light supplement plate can respond to weather changes, avoid rainwater erosion during rainfall, and adjust the angle of the light supplement plate according to local light characteristics to increase the light intensity in the plant growth box when the external light intensity is weak; the principle is that the water purification cover will rotate and fall after absorbing water and increasing in weight, and block the rainwater above the plant growth box to prevent the continuous erosion of the plant growth box from causing nutrient loss, at which time the light supplement plate is attached to the plant growth box by the pulling of the pulling rope; when the rainfall stops, the water absorbed in the water purification cover gradually evaporates, and when the weight decreases to a certain critical value, the force in the cover plate control box is greater than the weight of the water purification cover, causing the water purification cover to rise, so that the plants in the plant growth box can normally receive sunlight, at which time the light supplement plate opens under the action of its own weight;

[0037] 3. The cover plate control box of the present application automatically controls the opening and closing of the water purification cover and the light supplement plate under the change in weight of the water purification cover, and the spring, magnet and pulling rope combination control mode in the cover plate control box can make the water purification cover and the light supplement plate better enter the predetermined position; when the water purification cover falls, the light supplement plate is closed due to the action of the pulling rope, avoiding damage to the components of the light supplement plate by rainwater impact; when the water purification cover rises to a certain height, the force provided by the spring in the cover plate control box changes to the force provided by the magnet, and when the two magnets are attached, the pulling rope no longer moves, fixing the angle of the water purification cover and the light supplement plate, avoiding the shaking of the light supplement plate due to wind or other environmental influences, thereby affecting the light supplement efficiency;

[0038] 4. The cement blanket and the degradable waterproof plastic film of the present application are closely attached in the order of the cement blanket on top and the degradable waterproof plastic film on the bottom, and are laid in the order from top to bottom to fill the water interception ditch, the slope and the side ditch, and only need to be watered to be integrally formed; the degradable waterproof plastic film can prevent water from penetrating into the expansive soil slope during watering, causing slope body expansion and damage, and the hardened cement blanket can effectively prevent rainwater from entering the slope body, maintaining a relatively stable state of the internal moisture of the slope body, which is helpful to the stability of the slope body;

[0039] 5. The self-consolidation anchor rod of the present application can pass through the cement blanket and the degradable waterproof plastic film when driving into the slope body, so that the cement blanket and the degradable waterproof plastic film can be more closely attached to the slope surface; the circular ring-shaped position limiter on the outer side of the self-consolidation anchor rod can make the exposed length of the self-consolidation anchor rod uniform, which is conducive to the connection of the self-consolidation anchor rod and the vegetation box; the self-consolidation anchor rod cylinder can make the slope body more compact and provide anchoring effect for the slope body; after the self-consolidation anchor rod is fixed, the automatic water supply rod is pushed into the self-consolidation anchor rod, so that the push type anchoring head and the small anchoring sharp cylinder in the self-consolidation anchor rod are extruded into the slope body; the reaction strip in the small anchoring sharp cylinder can contact and cement with the expansive soil, and the small anchoring sharp cylinder can also provide additional anchoring effect, which together increases the anchoring capacity of the self-consolidation anchor rod and the stability of the slope body; the arrangement of the vegetation box on the slope surface can prevent the occurrence of single runoff on the slope surface during rainfall, and weaken the erosion effect of rainwater on the slope surface and the damage to the vegetation box;

[0040] 6. When repairing the high and steep expansive soil slope, the present application effectively simplifies the repair process and construction steps, reduces the required manpower and material costs, and only needs to install the components in sequence according to the steps to quickly and efficiently reinforce and green the slope body; the construction method avoids large-area backfilling and excavation on the high and steep slope surface, ensures the stability of the undisturbed soil slope body, and uses the combination of cement blanket covering and self-consolidation anchor rod anchoring, which has fast repair time, ideal effect and can effectively stabilize the slope body.

[0075] Step one: clean the slope surface, use the removed floating soil to improve its gradation and reasonably mix additives, organic matter and microorganisms to make it suitable for plant growth, uniformly mix plant seeds in the improved soil and put them into the plant growth bag 4.5 for subsequent use;

[0076] Step two: dig a water interception ditch 1.3 at a distance of 5 meters from the outer edge of the slope top, set up a side ditch 1.4 at the slope foot, tightly adhere the cement blanket 1.1 and the degradable waterproof plastic film 1.2 in the order of the cement blanket 1.1 on top and the degradable waterproof plastic film 1.2 below, fix one end of the two on the slope top and cover the water interception ditch 1.3, and let the other end down from the slope top to cover the slope;

[0077] Step three: butt the prefabricated plant growth box 4 with the corresponding self-consolidation anchor rod 2, and drive the self-consolidation anchor rod 2 at the predetermined point, so that the self-consolidation anchor rod 2 penetrates through the cement blanket 1.1 and the degradable waterproof plastic film 1.2, and when the outer ring-shaped position limiter 2.4 of the self-consolidation anchor rod 2 presses the plant growth box 4 and the cement blanket 1.1, it reaches the predetermined depth, and the construction of the next self-consolidation anchor rod 2 can begin until the self-consolidation anchor rod 2 is installed at the predetermined point;

[0078] Step four: connect the vegetation box 4 and the self-consolidating anchor 2 with the ring-shaped limiters on the outside of the self-consolidating anchor 2, so that the vegetation box 4 and the self-consolidating anchor 2 are connected into a whole, and then push the automatic water supply rod 3 into the self-consolidating anchor 2, so that the push type anchoring head 2.3 and the small anchoring sharp cylinder 2.2 in the self-consolidating anchor 2 are extruded into the slope body 1. During the process, when the small anchoring sharp cylinder 2.2 penetrates the opening 2.5 and enters the slope body 1, the cutter 2.5.1 can cut the reaction strip in the small anchoring sharp cylinder 2.2, so that the reaction substance in the small anchoring sharp cylinder 2.2 contacts the soil to produce cementation. Then, insert the water supply pipe 3.2 into the reserved docking port of the water storage box 4.7 at the bottom of the vegetation box 4, and finally put the vegetation bag 4.5 into the vegetation box 4.

[0079] Step five: water conservation from the top of the slope, so that the cement blanket 1.1 hardens, and the excess water flows into the vertical edge ditch 1.4 along the slope protection structure. The water collected in the vertical edge ditch 1.4 is used as a supplement for subsequent water conservation. The water purifying cover 4.1 at the upper part of the vegetation box 4 filters water through activated carbon particles during the water pouring process and guides the water to the automatic water supply rod 3.
