Description

Technical Field

[0001] The present application relates to the technical field of slope protection, and in particular to an ecological reinforced composite slope protection system and a construction process. Background Art

[0002] With the rapid development of transportation infrastructure such as expressways and high-speed railways in my country, more and more granite residual soil slope problems are encountered in engineering construction. Granite residual soil has high strength in its natural state and poor water stability. Once it comes into contact with water, its cohesion decreases and it is very easy to disintegrate and soften, which can easily cause soil erosion and other phenomena. In recent years, engineering accidents such as slope instability caused by rain disasters on granite residual soil slopes have often occurred. Rainwater can easily cause serious erosion or local landslides on the slope surface, thus affecting the safe operation of the project.

[0003] In the protection of granite residual soil slopes, traditional protection methods are widely used in engineering practice because of their wide material sources, safety and reliability, can effectively reduce the slope from rainwater erosion, and have the function of reinforcing the slope soil. For example, shotcrete is a commonly used engineering protection method for granite residual soil slopes. Although this protection method has good effects, the engineering cost is expensive, and it is difficult to restore the vegetation to its original state, which seriously affects the construction of the ecological environment. For ecological protection, several methods currently widely used mainly include skeleton grass slope protection, ecological bag slope protection, turf slope protection and foreign soil spraying. The use of ecological slope protection can reinforce the surface soil of the slope, effectively inhibit the soil and water loss of the slope, and play a certain role in promoting the restoration of the ecological environment. However, most of the protection forms cannot protect the newly excavated slopes in time, resulting in the grass seeds being easily washed away by rainwater before the vegetation grows out in the early stage of protection, resulting in a low survival rate of plants. Summary of the invention

[0004] In order to timely protect the slope after excavation and reduce the situation where grass seeds are washed away by rainwater, the present application provides an ecological reinforced composite slope protection system and construction process.

[0005] In the first aspect, the present application provides an ecological reinforced composite slope protection system, which adopts the following technical solutions: An ecological reinforced composite slope protection system, comprising a base layer, a planting trough, an anchor assembly and a pressing assembly; the base layer is used to be laid on the slope, and the planting trough is laid on the base layer; the anchor assembly comprises a fixed anchor rod and a locking rod, the fixed anchor rod is inserted into the slope, and the locking rod is connected to the fixed anchor rod; The planting trough includes a trough body, an edge plate and a protective net, wherein the edge plate is connected to the edge of the trough body, and the protective net covers the top side of the trough body; the pressing assembly includes a pressing cover and a locking piece, wherein the locking rod passes through the pressing cover, the locking piece is connected to the locking rod, and the locking piece locks the position of the pressing cover so that the pressing cover presses the edge plate, and the edge of the protective net is pressed between the pressing cover and the edge plate.

[0006] By adopting the above technical solution, the anchor rods are fixed and inserted into the slope, and the pressure cover presses the edge plate, which can enhance the stability of the planting trough and reduce the loosening caused by external factors. The protective net is pressed between the pressure cover and the edge plate to fix the position of the protective net. The protective net covers the top side of the trough body, improves the stability of the soil inside the trough body, reduces the risk of soil loss in the trough body, and allows rainwater to be effectively collected and gradually penetrated into the planting trough, providing the necessary water supply for the plants, thereby improving the survival rate of vegetation and the greening effect.

[0007] Optionally, the pressure cover is connected to an abutment rod, and the abutment rod passes through the protective net and abuts against the edge plate.

[0008] By adopting the above technical solution, the abutment rod passes through the protective net and abuts against the edge plate. The abutment rod can hook the protective net, reduce the displacement of the protective net during subsequent use, and improve the stability of the protective net.

[0009] Optionally, the pressure cover is connected to an inner cylinder, and the inner cylinder is inserted into the fixed anchor rod; the side wall of the fixed anchor rod is hinged with an expansion plate, and the inner cylinder pushes the expansion plate to expand.

[0010] By adopting the above technical solution, during the process of inserting the fixed anchor into the slope, the expansion plate is in a retracted state, which is conducive to inserting the fixed anchor into the slope. Subsequently, the inner tube is inserted into the fixed anchor to push the expansion plate to expand, thereby increasing the radial volume of the fixed anchor, enhancing the anchoring force of the fixed anchor, and reducing the risk of the fixed anchor being pulled out.

[0011] Optionally, the inner tube is connected to a water diversion filling block, the pressure cover is connected to a water diversion block, and the water diversion filling block is in contact with the water diversion block; the edge plate is connected to a water guide block, the water guide block extends into the trough body, and the water guide blocks are in contact with the water diversion blocks; the moisture in the slope passes through the water diversion filling block, the water diversion block and the water guide block in turn and enters the trough body.

[0012] By adopting the above technical solution, the water in the slope enters the trough body through the water diversion filling block, the water diversion block and the water guide block in sequence, which can effectively introduce the water inside the slope into the trough body. In this way, the necessary water supply is provided to the plants when they are short of water, thereby improving the survival rate of the plants. At the same time, this design reduces the need for external irrigation, reduces maintenance costs, and improves the ecological protection effect.

[0013] Optionally, after the unfolding plate is unfolded, the unfolding plate is tapered in the direction from the pressure cover to the fixed anchor rod.

[0014] By adopting the above technical solution, the unfolding plate is gradually contracted after being unfolded, which increases the contact area between the fixed anchor rod and the slope soil and improves the anchoring force of the fixed anchor rod. In addition, when the fixed anchor rod is subjected to a pull-out force, the soil of the slope causes the unfolding plate to unfold at a larger angle, thereby making the fixed anchor rod have a higher pull-out resistance.

[0015] Optionally, a water storage cavity is opened at the bottom end of the fixed anchor rod, and the expansion plate guides the moisture in the slope into the water storage cavity; the water storage cavity is filled with a water storage block, and the water storage block is in contact with the water diversion filling block.

[0016] By adopting the above technical solution, the unfolded expansion plate is in a tapered shape, which is conducive to the unfolded plate guiding the moisture in the slope to the water storage cavity, and the water storage cavity can effectively collect the moisture in the slope. When the inner tube is inserted into the fixed anchor rod, the water storage block filled in the water storage cavity contacts the water diversion filling block, ensuring that the water enters the water diversion filling block from the water storage cavity and is then transmitted to the planting trough, thereby providing the necessary water supply for the plants and improving the survival rate of the plants.

[0017] Optionally, the water diversion filling block is provided with a through hole, the locking rod passes through the through hole, the locking rod is connected to a water storage cup, the water storage cup is in contact with the water diversion filling block, and the water storage cup is used to store water.

[0018] By adopting the above technical solution, the water storage cup can collect excess water in the rainy season. When the external water source is insufficient, the water in the water storage cup can be used to replenish water in the tank through the water diversion filling block, thereby improving the survival rate of plants and reducing the phenomenon of plant death due to water shortage. In addition, in the process of the water diversion filling block guiding water from bottom to top, the excess water in the water diversion filling block can be temporarily stored in the water storage cup, which is conducive to the water diversion filling block to gradually lift the water upward.

[0019] Optionally, the locking member includes a nut, the nut is threadedly connected to the locking rod, and the nut is pressed against the pressure cover.

[0020] By adopting the above technical solution, after the locking rod passes through the gland, the nut is threadedly connected to the locking rod, and the nut presses the gland tightly, so that the gland presses the edge plate, and the inner cylinder pushes the expansion plate to expand. The threaded connection method is convenient for installation and disassembly, and is convenient for maintenance and replacement of parts.

[0021] Optionally, the planting troughs are arranged in multiple rows, and drainage channels are formed between the planting troughs in adjacent rows. Permeable bricks are arranged in the drainage channel, and the permeable bricks are embedded between adjacent pressure covers. The permeable bricks press the protective net onto the edge plate.

[0022] By adopting the above technical solution, the permeable bricks press the protective net onto the edge board, which can reduce the falling of the protective net. The drainage channels are used to drain water between adjacent planting troughs. The permeable bricks have good water permeability, which can allow some rainwater to penetrate into the slope, ensuring the water supply required for plant growth, which is conducive to the rapid recovery of vegetation and ecological reconstruction.

[0023] In a second aspect, the present application also provides a construction process of an ecological reinforced composite slope protection system, using the above-mentioned ecological reinforced composite slope protection system, comprising the following steps: S1: Level the slope surface and lay the base layer on the slope surface; S2: Insert anchor components at intervals on the slope; S3: Lay planting troughs on the slope and fill the troughs with planting soil and grass seeds; S4: Hang a protective net on the top of the tank; S5: Connect the pressing assembly with the anchoring assembly so that the pressure cover presses the protective net; S6: embed permeable bricks between adjacent glands so that the permeable bricks press the protective net onto the edge plate.

[0024] In summary, the present application includes at least one of the following beneficial effects: 1. The locking piece is threadedly connected to the locking rod, and the locking piece is pressed against the gland, so that the gland presses the edge plate, and when the inner tube is inserted into the fixed anchor rod, the inner tube pushes the expansion plate to expand, and the expansion plate can enhance the anchoring force of the fixed anchor rod, reduce the situation that the fixed anchor rod is pulled out, and improve the stability of the planting trough; 2. The water in the slope is transferred step by step through the water storage block, water diversion filling block, water diversion block and water guide block and finally enters the trough body, providing water supply for the plants when they are short of water, thus promoting the growth and survival rate of the plants; 3. The pressure cover and permeable bricks are pressed together to fix the position of the protective net, so that the protective net can effectively protect the top side of the trough, reduce the loss of soil in the trough, and enhance the effect of ecological protection.
