Description

Technical Field

[0001] The invention relates to the technical field of slope engineering construction, and in particular to a water storage and drainage system for maintaining slope stability. Background Art

[0002] Common slope protection and management engineering measures include engineering slope protection, grid grass slope protection, turf slope protection, etc.; among them, simple engineering slope protection is a rigid structure, which cannot adapt to the deformation of the slope, has high cost and is not conducive to ecological protection; although grid grass slope protection and turf slope protection are beneficial to environmental protection, they cannot effectively prevent the generation and development of slope cracks because there is no improvement of the slope soil, which is also prone to slope engineering diseases.

[0003] It should be pointed out that the stability of the slope is affected by many factors, and the presence or absence of water and its amount are one of the key factors.

[0004] When the slope contains a lot of water, its impact includes the following aspects, specifically:

[0005] 1. Increased pore water pressure: When the water content of the slope increases, such as rainfall, rising groundwater levels or reservoir storage, the water pressure in the pores of the soil or rock increases, which will reduce the effective normal stress of the rock and soil mass, thereby reducing the shear strength of the rock and soil mass and increasing the sliding force of the rock and soil mass, which may cause landslides or collapses;

[0006] 2. Floating effect: For partially submerged slopes, water will produce buoyancy force on the toe of the slope, reducing the support force at the toe of the slope and further reducing the stability of the slope;

[0007] 3. Chemical action: Water can dissolve certain minerals in soil or rock, changing its physical and chemical properties, such as causing soil softening or rock mass deterioration, affecting the mechanical properties of the slope;

[0008] 3. Erosion: The scouring of the slope surface by water flow can carry away fine particles, which in turn leads to slope erosion, making the slope structure loose and reducing stability.

[0009] 4. Hydrostatic pressure: The groundwater level rises to the inside of the slope to form hydrostatic pressure, which in turn increases the lateral force, which may cause the slope to become unstable.

[0010] When the water content of the slope is low, its impact includes the following aspects, specifically:

[0011] 1. Shrinkage and cracking: When there is a lack of water, especially in areas with drought or significant seasonal climate changes, the soil will shrink and crack due to evaporation of water. These cracks reduce the integrity and cohesion of the soil, thereby increasing the possibility of sliding surfaces;

[0012] 2. Strength changes: Some soil types (such as expansive soils) become more brittle and prone to brittle fracture under dry conditions, thus affecting the stability of the slope;

[0013] 3. Impact on vegetation: Insufficient water will affect the growth of vegetation on the slopes, and the consolidation effect of vegetation roots on the soil will be weakened, thereby reducing the natural reinforcement effect on the slopes and increasing the risk of landslides.

[0014] In view of the above-mentioned influence of slope moisture content on slope stability, whether too much or too little water can affect the stability of the slope through different mechanisms. Therefore, in the design and management of slope engineering, reasonable drainage and moisture retention measures are essential to maintain the stability of the slope. Therefore, it is necessary to design and develop a system that can intelligently and automatically store and drain water from the slope according to the slope moisture content to maintain the stability of the slope. Summary of the invention

[0015] The purpose of the present invention is to provide a water storage and drainage system for maintaining slope stability in view of the deficiencies in the prior art. The water storage and drainage system for maintaining slope stability can effectively regulate and control the water content of the slope, thereby effectively avoiding adverse effects on slope stability caused by excessive or insufficient water content in the slope, and can effectively improve slope stability.

[0016] To achieve the above object, the present invention is implemented through the following technical solutions.

[0017] A water storage and drainage system for maintaining slope stability, comprising a drainage pipe assembly and an automatic water replenishment assembly;

[0018] The drainage pipe assembly includes a plurality of transverse assembled pipes extending horizontally along the slope surface, a plurality of oblique assembled pipes extending obliquely along the slope surface, and a plurality of plastic capillaries inserted into the original soil of the slope surface. The upper end of each plastic capillary extends upward from the slope surface, and all the transverse assembled pipes are vertically staggered and connected with all the oblique assembled pipes. Each transverse assembled pipe is connected with the plastic capillary at the corresponding position.

[0019] The transverse assembled pipes and the oblique assembled pipes are spaced apart from the slope surface, the slope surface is paved with a sand cushion layer, and the upper surface of the sand cushion layer is paved with a perlite layer;

[0020] The automatic water replenishment component includes a water pump, a plurality of water replenishment pipes located above the transverse assembled pipe, and a plurality of wireless temperature and humidity sensors buried in the original soil on the slope surface. The water outlet of the water pump is connected to each water replenishment pipe through a water delivery pipeline; the water pump is equipped with an intelligent automatic sensing system, the water pump is electrically connected to the intelligent automatic sensing system, and each wireless temperature and humidity sensor is wirelessly connected to the intelligent automatic sensing system;

[0021] The water storage and drainage system for maintaining slope stability also includes a number of prefabricated concrete frame beams paved on the perlite layer, and the lower ends of the prefabricated concrete frame beams are embedded in the sand cushion layer; a rotating nozzle is installed at the junction of every four prefabricated concrete frame beams, and the rotating nozzle is connected to the water supply pipe at the corresponding position; a planting area is formed inside the prefabricated concrete frame beam, and the planting area is paved with a foreign soil layer for planting cold-resistant and water-retaining vegetation.

[0022] The water storage and drainage system for maintaining slope stability also includes a water reservoir, which is connected to the water inlet of the water pump through a water pipeline.

[0023] Wherein, a solar panel is installed on the top of the slope, and the power transmission end of the solar panel is electrically connected to the water pump through a power transmission line.

[0024] Wherein, a drainage ditch is provided at the top of the slope.

[0025] Compared with the prior art, the present invention has the following beneficial effects, specifically: when the water content of the slope is too high, the water will be discharged with the assistance of plastic capillaries, the water will be gathered through the horizontal assembled pipes and then flow to the bottom of the slope through the oblique assembled pipes, the perlite can store water and the sand cushion layer can drain water; when the water content of the slope is too low, the drought-resistant and water-retaining vegetation itself has the ability to conserve water, and each temperature and humidity sensor will feed back the humidity value signal to the intelligent automatic sensing system in real time. When the humidity value of the soil is lower than the threshold, the intelligent automatic sensing system controls the water pump to start, and the water pump supplies water to the water supply pipe through the water supply pipe. The water entering the water supply pipe is sprayed out through the rotating nozzle, and the rotating nozzle is sprayed to the surroundings to achieve the purpose of water replenishment; therefore, the present invention can effectively regulate and control the water content of the slope, and thus can effectively avoid the adverse effects on the stability of the slope caused by excessive or insufficient water content of the slope, and can effectively improve the stability of the slope.

[0036] Furthermore, Figures 1 to 3 As shown, the automatic water replenishment component includes a water pump 7, a plurality of water replenishment pipes 8 located above the transverse assembled pipe 2, and a plurality of wireless temperature and humidity sensors buried in the original soil on the slope surface of the slope 1 (not shown in the figure). The water outlet of the water pump 7 is connected to each water replenishment pipe 8 through a water supply pipe 9; the water pump 7 is equipped with an intelligent automatic sensing system (not shown in the figure), the water pump 7 is electrically connected to the intelligent automatic sensing system, and each wireless temperature and humidity sensor is wirelessly connected to the intelligent automatic sensing system.

[0037] In addition, if Figure 1 and Figure 2As shown, the water storage and drainage system for maintaining slope stability also includes a number of assembled concrete lattice beams 10 paved on the perlite layer 6, and the lower ends of the assembled concrete lattice beams 10 are embedded in the sand cushion layer 5; a rotating nozzle 11 is installed at the junction of every four assembled concrete lattice beams 10, and the rotating nozzle 11 is connected to the water supply pipe 8 at the corresponding position; a planting area 12 is formed inside the assembled concrete lattice beam 10, and the planting area 12 is paved with a foreign soil layer 13 for planting cold-resistant and water-retaining vegetation.

[0038] In addition, a drainage ditch 17 is provided on the top of the slope 1 .

[0039] For the storage and drainage system for maintaining slope stability of the first embodiment, the following method is adopted to realize the slope surface construction of the slope 1, specifically:

[0040] Step a, burying a number of wireless temperature and humidity sensors at a certain distance inside the original soil at the slope surface of slope 1, and then burying each wireless temperature and humidity sensor with the original soil;

[0041] Step b, inserting a plurality of plastic capillaries 4 on the original soil on the slope surface of the slope 1, and ensuring that the upper end of each plastic capillary tube 4 extends above the slope surface of the slope 1;

[0042] Step c, connecting and installing the transverse assembled pipe 2, the plastic capillary tube 4 is clamped by the transverse assembled pipe 2, and each plastic capillary tube 4 is connected with the transverse assembled pipe 2 at the corresponding position, and the transverse assembled pipe 2 is spaced from the original soil of the slope 1;

[0043] Step d, laying a sand cushion layer 5 and a perlite layer 6 in sequence below the transverse assembled pipe 2, wherein the perlite layer 6 is located above the sand cushion layer 5;

[0044] Step e: after the sand cushion layer 5 and the perlite layer 6 are laid, the assembled concrete frame beam 10 is installed, and the assembled concrete frame beam 10 passes through the transverse assembled pipe 2 and is embedded in the sand cushion layer 5;

[0045] Step f, inserting the oblique assembled pipe 3 and the water supply pipe 8 into the assembled concrete lattice beam 10, and the oblique assembled pipe 3 is connected with the transverse assembled pipe 2;

[0046] Step g, laying a foreign soil layer 13 in the planting area 12 of the assembled concrete lattice beam 10, and planting drought-resistant and water-retaining vegetation in the foreign soil layer 13;

[0047] Step h: installing a rotating sprinkler 11 at the junction of every four assembled concrete lattice beams 10, and connecting the rotating sprinkler 11 to the water supply pipe 8 at the corresponding position;

[0048] Step i: connect the water outlet of the water pump 7 to each water supply pipe 8 through the water delivery pipe 9.

[0049] During the operation of the storage and drainage system for maintaining slope stability in the first embodiment, the storage and drainage mechanism is as follows:

[0050] 1. When it rains, the drainage ditch 17 will drain away some of the water, and the drought-resistant and water-retaining vegetation covered on the imported soil layer 13 will absorb some of the water and resist the erosion of some of the water;

[0051] 2. When the rainfall is too heavy, the water that cannot be contained by the drought-resistant and water-retaining vegetation covered by the imported soil layer 13 will be discharged with the assistance of the plastic capillary 4. The water will be collected through the horizontal assembled pipe 2 and then flow to the bottom of the slope through the oblique assembled pipe 3. If the rainfall is still heavy, the perlite under the assembled concrete frame lattice beam will store water, and the sand cushion layer 5 under the perlite will be used for drainage.

[0052] 3. When there is a lack of water or even drought, the imported soil layer 13 is covered with drought-resistant and water-retaining vegetation, which has a certain ability to conserve water. During this process, each temperature and humidity sensor feeds back the humidity value signal to the intelligent automatic sensing system in real time. When the humidity value of the soil is lower than the threshold, the intelligent automatic sensing system controls the water pump 7 to start, and the water pump 7 supplies water to the water supply pipe 8 through the water supply pipe 9. The water entering the water supply pipe 8 is sprayed out through the rotating nozzle 11, and the rotating nozzle 11 sprays it to the surroundings to achieve the purpose of water replenishment.

[0053] Based on the above, it can be seen that the water storage and drainage system for maintaining slope stability of the first embodiment can effectively regulate and control the water content of the slope 1, thereby effectively avoiding the adverse effects on the stability of the slope 1 caused by excessive or insufficient water content in the slope 1, and can effectively improve the stability of the slope 1.

[0054] Embodiment 2, as Figure 1 and Figure 2 As shown, the difference between the second embodiment and the first embodiment is that the water storage and drainage system for maintaining slope stability also includes a water reservoir 14, and the water reservoir 14 is connected to the water inlet of the water pump 7 through a water pipe 9.

[0055] When water replenishment is required, the water pump 7 supplies the water in the water reservoir 14 to replenish the slope 1 .

[0057] When working, the solar panel 15 can generate electricity, thereby providing electrical energy to the water pump 7 .

[0058] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes.
