Description

Technical Field

[0001] The invention relates to the technical field of slope reinforcement, and in particular to a cement blanket slope protection structure and a construction method thereof. Background Art

[0002] The present invention relates to a cement blanket slope protection structure, and its background technical field mainly focuses on slope protection technology, especially slope protection structure based on cement blanket. In the existing technology, the slope protection structure mostly adopts a support structure of hanging mesh spray anchor + prestressed anchor rod (or soil nail), in which the sprayed concrete process is one of the key processes. However, these traditional methods have some disadvantages, such as great construction difficulty, serious material waste, environmental pollution and harm to the health of construction workers. In addition, the existing cement blankets generally need to be protected by protective structures when in use, but these protective structures are not easy to protect the ecological environment when in use, and rainwater accumulation is prone to occur, and the stability is relatively low.

[0003] In the field of slope protection and support structures, traditional construction methods mostly use a support structure that combines mesh spray anchors with prestressed anchor rods (or soil nails), in which the sprayed concrete process is one of the key processes. However, these traditional methods have some shortcomings:

[0004] Environmental pollution and health hazards: When using dry spraying, concrete needs to be mixed on site, which will generate a lot of dust, cause environmental pollution, and endanger the health of construction workers.

[0005] Construction difficulty and material waste: wet shotcrete construction is difficult and wastes a lot of materials. If you use spray (spray) thin layer mortar + cement blanket instead of traditional shotcrete, you can reduce the construction difficulty and improve environmental protection.

[0006] Ecological protection and drainage issues: Traditional cement blankets are not easy to grow green plants, which is not conducive to ecological environment protection; at the same time, due to the solid structure inside the cement blanket, it is difficult to drain and easily leads to rainwater accumulation.

[0007] Structural stability issues: Traditional protective structures generally directly apply concrete to the slope surface and then lay cement blankets on the concrete surface. It is not easy to reinforce it, which affects the stability of the protective structure.

[0008] Demand for impermeability: As a common construction material, ordinary concrete has poor impermeability due to various factors in its preparation process. The market has put forward a demand for impermeable concrete. Common methods are to add air-entraining admixtures or expansive admixtures, but these methods may have an adverse effect on the mechanical properties of concrete while improving the impermeability.

[0009] Three-dimensional fiber skeleton porous materials: In the field of new materials, three-dimensional porous materials are widely used due to their good thermal insulation and noise absorption properties. In the prior art, the skeleton materials of three-dimensional porous materials mainly include solid particles and micro-nano fibers, but their mechanical properties are poor, the preparation process is cumbersome, and the cost is high.

[0010] Porous absorbent fabric: In the patent background technology, porous absorbent fabric such as porous non-woven fabric plays a key role in cement blanket slope protection structure due to its special structure and performance, but the application and optimization of porous absorbent fabric in the prior art still needs further research and development.

[0011] In summary, the existing technology has certain limitations in terms of construction methods, material selection, ecological protection, drainage capacity, structural stability and anti-seepage performance of slope protection and support structures. Summary of the invention

[0012] In order to solve the above problems, the present invention proposes a cement blanket slope protection structure, which is designed to improve the stability of the slope protection structure, while reducing construction difficulty and material waste, improving construction efficiency, and enhancing the ability to protect the ecological environment. The present invention adopts the following technical solutions:

[0013] A cement blanket slope protection structure comprises a slope structure and a cement blanket, wherein the cement blanket is laid on the surface of the slope structure, the cement blanket comprises a three-dimensional fiber composite skeleton woven from a porous water-absorbing fabric and a fiber-reinforced material, and an anti-seepage dry concrete mixture, wherein the porous water-absorbing fabric is arranged at the bottom of the cement blanket, the three-dimensional fiber composite skeleton is fixed at the upper part, the middle layer of the three-dimensional fiber composite skeleton is separated and filled with an anti-seepage dry concrete mixture, and a quick-dissolving bottom lining is arranged at the bottom of the porous water-absorbing fabric, the cement blanket is rectangular, and a reaction capsule is wrapped at each of its four corners and the center position, respectively, the reaction capsule comprises a waterproof rubber surface layer, a built-in polymer grouting material and a discharge port, and the discharge port is arranged at the bottom of the waterproof rubber surface layer and faces the soil layer A layer of water-soluble sealing film is sealed at the discharge port, and the outside of the reaction capsule is squeezed tightly by the hydraulic micro-expansive cement. When the reaction capsule is used as a soil consolidation material, water is sprayed directly after the cement blanket is laid for maintenance, so that the hydraulic micro-expansive cement hardens and further squeezes the waterproof rubber surface layer and the built-in polymer grouting material. After the water-soluble sealing film is dissolved, the built-in polymer grouting material gradually invades the soil layer and hardens the soil layer; when the reaction capsule is used as an auxiliary material for deep soil, an anchor is driven into the corresponding reaction capsule at each corresponding position and extends into the interior of the slope structure. The anchor can puncture the reaction capsule and bring the built-in polymer grouting material in the reaction capsule into the interior of the slope structure, and the built-in polymer grouting material and the anchor form an external diffusion tree fork pile.

[0014] Furthermore, the porous water-absorbent fabric is a porous non-woven fabric, and the fiber reinforcement material is PET fiber.

[0015] Furthermore, the anti-seepage dry concrete mixture uses sodium methyl silicate cement powder, and the material of the instant lining is mineral-source potassium humate.

[0016] Furthermore, the nail body of the anchor nail is provided with a plurality of material-carrying protrusions, and the material-carrying protrusions are arranged at intervals along a spiral route, and the material-carrying protrusions are small vertical rectangular baffles.

[0017] Also included is a construction method for a cement blanket slope protection structure, comprising the following steps:

[0018] Step 1: Make cement blanket;

[0019] Step 2: Shovel the slope structure flat and clean up the plant residues and stones;

[0020] Step 3: Lay the cement blanket on the surface of the slope structure;

[0021] Step 4: Sprinkle water on the cement blanket, the instant lining begins to dissolve, the anti-seepage dry concrete mixture, water, and the instant lining begin to penetrate into the slope structure, and the water-soluble sealing film of the reaction capsule begins to dissolve;

[0022] Step 5: Immediately after the watering is completed, the anchors and reaction capsules are matched one by one and screwed into the slope structure. The cement inside the reaction capsule follows the anchors into the slope structure and diffuses outward, and reacts with the infiltrated water.

[0023] Step 6: Complete the construction of the cement blanket slope protection structure after a period of maintenance.

[0024] Furthermore, step one also includes: the step of making the cement blanket includes:

[0025] (1) Making anti-seepage dry concrete mixture;

[0026] (2) spreading anti-seepage dry concrete mixture and fiber reinforcement material on the upper surface of the instant lining;

[0027] (3) placing a counter-force capsule at the corresponding position;

[0028] (4) Cover the upper surface of all materials with a porous water-absorbent fabric, and weave the cement blanket into a three-dimensional fiber composite skeleton woven with the fiber-reinforced material until a complete rectangular cement blanket is woven.

[0029] Furthermore, the step of preparing an anti-seepage dry concrete mixture includes: using 30% sodium methyl silicate stock solution to dilute it with water at a ratio of 1:12-15 to a concentration of 3% to prepare a diluted waterproofing agent, which is used for cement mortar or mixed into concrete in the ratio of cement: sand: water: diluted waterproofing agent = 1:2:0.4:0.05-0.08.

[0030] The cement blanket slope protection structure and the construction method thereof of the present invention have the following significant beneficial effects:

[0031] (1) By arranging a combination of porous water-absorbent fabric and anti-seepage dry concrete mixture, it is possible to ensure that water enters the cement blanket during water sprinkling and curing, and form a complete waterproof layer with the porous water-absorbent fabric when the anti-seepage dry concrete mixture completes the hydration reaction and hardens. The formed slope protection structure is not easily affected by rain erosion, resulting in sand and soil loss and avoiding slope structure collapse. The porous water-absorbent fabric is made of porous non-woven fabric and fiber reinforcement material, which is easy to weave into a more stable three-dimensional fiber composite skeleton. In particular, the porous non-woven fabric begins to swell after water spraying to form an anti-seepage layer, which greatly improves the crack resistance of the cement blanket.

[0032] (2) The use of a quick-dissolving base liner allows it to dissolve on its own after watering. The anti-seepage dry concrete mixture wrapped in it can be covered in accordance with the contour of the slope structure surface, so that after hardening, the cement blanket can be better attached to the slope structure surface. The mineral potassium humate used in the quick-dissolving base liner dissolves quickly in water and has a strong anti-flocculation ability. It can directly improve the soil of the slope structure, increase the ground temperature and disease resistance of the slope structure, and further reduce the risk of corrosion and collapse of the slope structure.

[0033] (3) The waterproof rubber surface of the reaction capsule is elastic, and a water-soluble sealing film is sealed at the discharge port. The outside of the reaction capsule is squeezed tightly by hydraulic micro-expansive cement. When the reaction capsule is used as a soil consolidation material, water is sprayed directly after the cement blanket is laid to cure it, so that the hydraulic micro-expansive cement hardens and further squeezes the waterproof rubber surface and the built-in polymer grouting material. After the water-soluble sealing film is dissolved, the built-in polymer grouting material is squeezed by the rebound force of the waterproof rubber surface and gradually penetrates into the soil layer to harden the soil layer; and when the reaction capsule is used as an auxiliary material for deep soil, an anchor is driven into the slope structure at each corresponding reaction capsule. Internally, the anchor can puncture the reaction capsule and bring the built-in polymer grouting material inside the reaction capsule into the slope structure. The resilience of the waterproof rubber surface makes it easier to release and diffuse. At the same time, the material-carrying protrusion of the anchor can bring cement into the anchor gap to achieve external diffusion of the gap, thereby fixing the anchor and the branch pile of the slope structure soil layer. By utilizing the support advantage of the waterproof rubber surface, the stability of the entire reaction capsule is guaranteed. At the same time, the reaction capsule does not dissolve, ensuring that the cement inside the reaction capsule has not undergone hydration reaction before the anchor is driven into the soil layer, thereby ensuring the high dispersion of the cement following the anchor into the slope structure soil layer.

[0034] (4) The construction method utilizes the construction process of first sprinkling water and then anchoring. On the one hand, it can solve the problem that the impact force during the anchoring process causes the anti-seepage dry concrete mixture of the cement blanket to be lifted up, resulting in dust pollution and material loss. On the other hand, it can synchronize the process of anchoring and the process of cement blanket curing, shortening the entire construction period and improving construction efficiency.

[0045] Embodiment 1:

[0046] See also Figure 1-5 As shown, a cement blanket slope protection structure includes a slope structure 100 and a cement blanket 101. The cement blanket 101 is laid on the surface of the slope structure 100. The cement blanket 101 includes a three-dimensional fiber composite skeleton 102 woven from a porous non-woven fabric and PET fibers, and sodium methyl silicate cement powder. The porous non-woven fabric is arranged at the bottom of the cement blanket 101, and the three-dimensional fiber composite skeleton 102 is fixed on the upper part. The middle layer of the three-dimensional fiber composite skeleton 102 is separated and filled with sodium methyl silicate cement powder. The bottom of the porous non-woven fabric is provided with a mineral source potassium humate lining. The cement blanket 101 is rectangular, and a reaction capsule 105 is wrapped at each of its four corners and the center position. The reaction capsule 105 includes a waterproof rubber surface layer 108, a built-in polymer grouting material 109 and a discharge port 110. The discharge port 110 is arranged at the bottom of the waterproof rubber surface layer 108 and faces the soil layer. A layer of water-soluble sealing film 111 is sealed at the opening 110, and the outside of the reaction capsule 105 is squeezed tightly by the hydraulic micro-expansive cement. When the reaction capsule 105 is used as a soil consolidation material, water is sprayed directly after the cement blanket 101 is laid for curing, so that the hydraulic micro-expansive cement hardens and further squeezes the waterproof rubber surface layer 108 and the built-in polymer grouting material 109. After the water-soluble sealing film 111 is dissolved, the built-in polymer grouting material 109 gradually penetrates into the soil layer to harden the soil layer; when the reaction capsule 105 is used as an auxiliary material for deep soil, an anchor 106 is driven into each corresponding reaction capsule 105 and extends into the interior of the slope structure 100. The anchor 106 can puncture the reaction capsule 105 and bring the built-in polymer grouting material 109 in the reaction capsule 105 into the interior of the slope structure 100, and the built-in polymer grouting material 109 brought in forms an external diffusion tree fork pile with the anchor 106.

[0047] The nail body of the anchor nail 106 is provided with a plurality of material-carrying protrusions 107 , and the material-carrying protrusions 107 are arranged at intervals along a spiral route, and the material-carrying protrusions 107 are small vertical rectangular baffles.

[0048] By arranging a combination of a porous water-absorbent fabric and an anti-seepage dry concrete mixture 103, it is possible to ensure that water enters the cement blanket 101 during watering and curing, and form a complete waterproof layer with the porous water-absorbent fabric when the anti-seepage dry concrete mixture 103 completes the hydration reaction and hardens. The formed slope protection structure is not easily affected by rain erosion to cause sand and soil loss and avoid the collapse of the slope structure 100. The porous water-absorbent fabric uses a porous non-woven fabric and a fiber-reinforced material that is easy to weave into a more stable three-dimensional fiber composite skeleton 102, and especially after water spraying, the porous non-woven fabric begins to swell to form an anti-seepage layer, which greatly improves the crack resistance of the cement blanket 101.

[0049] The use of the quick-dissolving base liner 104 can make the base liner dissolve by itself after sprinkling water, and the anti-seepage dry concrete mixture 103 wrapped therein can be covered in accordance with the contour of the surface of the slope structure 100, so that the cement blanket 101 can be better attached to the surface of the slope structure 100 after hardening. The mineral potassium humate used in the quick-dissolving base liner 104 dissolves quickly in water and has a strong anti-flocculation ability. It can directly improve the soil of the slope structure 100, increase the ground temperature and disease resistance of the slope structure 100, and further reduce the risk of corrosion and collapse of the slope structure 100.

[0050] The waterproof rubber surface layer 108 of the reaction capsule 105 is elastic, and a water-soluble sealing film 111 is sealed at the discharge port 110, and the outside of the reaction capsule 105 is squeezed tightly by hydraulic micro-expansive cement. When the reaction capsule 105 is used as a soil consolidation material, the cement blanket 101 is laid and directly sprayed with water for curing, so that the hydraulic micro-expansive cement hardens and further squeezes the waterproof rubber surface layer 108 and the built-in polymer grouting material 109. After the water-soluble sealing film 111 is dissolved, the built-in polymer grouting material 109 is squeezed by the resilience of the waterproof rubber surface layer 108 and gradually penetrates into the soil layer to harden the soil layer; and when the reaction capsule 105 is used as an auxiliary material for deep soil, an anchor 106 is driven into the corresponding reaction capsule 105 and extends into the interior of the slope structure 100. 106 can puncture the reaction capsule 105 and bring the built-in polymer grouting material 109 inside the reaction capsule 105 into the slope structure 100. The resilience of the waterproof rubber surface layer 108 squeezes it to make it easier to release and diffuse. At the same time, the material-carrying protrusion 107 of the anchor 106 can bring cement into the gap of the anchor 106 to achieve external diffusion of the gap, thereby achieving the fixation of the anchor 106 and the tree branch pile of the soil layer of the slope structure 100. By utilizing the support advantage of the waterproof rubber surface layer 108, the stability of the entire reaction capsule 105 is guaranteed. At the same time, the reaction capsule 105 does not dissolve, ensuring that the cement inside the reaction capsule 105 has not undergone hydration reaction before the anchor 106 is driven into the anchor 106, thereby ensuring the high dispersion of the cement when following the anchor 106 into the soil layer of the slope structure 100.

[0051] Embodiment 2:

[0052] A construction method of a cement blanket slope protection structure comprises the following steps:

[0053] Step 1: Making a cement blanket 101:

[0054] (1) Making anti-seepage dry concrete mixture 103:

[0055] Use 30% sodium methyl silicate stock solution to dilute with water at a ratio of 1:12-15 to a concentration of 3% to make a diluted waterproofing agent, which is used in cement mortar or mixed into concrete in the following ratios: cement: sand: water: diluted waterproofing agent = 1:2:0.4:0.05-0.08;

[0056] (2) spreading the anti-seepage dry concrete mixture 103 and the fiber-reinforced material on the upper surface of the instant liner 104;

[0057] (3) placing the reaction capsule 105 at the corresponding position;

[0058] (4) Cover the upper surface of all materials with porous water-absorbent fabric, and weave the cement blanket 101 with a three-dimensional fiber composite skeleton 102 woven with fiber-reinforced materials until a complete rectangular cement blanket 101 is woven.

[0059] Step 2: Shovel the slope structure 100 and clean up its plant residues and rocks;

[0060] Step 3: Laying the cement blanket 101 on the surface of the slope structure 100;

[0062] Step 5: After the watering is completed, the anchors 106 and the reaction capsules 105 are immediately matched one by one and screwed into the interior of the slope structure 100. The built-in polymer grouting material 109 in the reaction capsule 105 follows the anchors 106 into the interior of the slope structure 100 and diffuses outward, and reacts with the infiltrated water.

[0063] Step 6: After a period of maintenance, the construction of the cement blanket 101 slope protection structure is completed.

[0064] The construction method utilizes the construction process of first sprinkling water and then anchoring the nails 106. On the one hand, it can solve the problem that the impact force during the driving of the anchors 106 causes the anti-seepage dry concrete mixture 103 of the cement blanket 101 to be lifted up, resulting in dust pollution and material loss. On the other hand, the process of driving the anchors 106 and the process of curing the cement blanket 101 are carried out simultaneously, shortening the entire construction period and improving construction efficiency.
