Ecological grid geotextile bag impermeable construction system

Abstract

This utility model relates to the technical field of riverbed seepage prevention construction, specifically an ecological grid geotextile bag seepage prevention construction system. It includes a ground surface and an ecological grid body. Irregularly shaped geotextile bags are evenly laid within the ecological grid body, symmetrically stacked and interlocked to reduce seepage gaps. A seepage-proof transition layer is provided at the contact surface of the stacked geotextile bags. A biological seepage-proof layer is laid on the upper surface of the geotextile bags to lock in moisture. By symmetrically stacking and interlocking the irregularly shaped geotextile bags at both ends, the gaps between the bags are structurally reduced. Compared to traditional rectangular bags, this reduces seepage channels by more than 30%. The seepage-proof transition layer utilizes the water-swelling properties of bentonite to fill the tiny gaps at the contact surface of the bags, forming the first seepage barrier. The polyurethane sealant injected between bags on the same side has high elasticity and adhesion, adapting to bag settlement and deformation, blocking lateral seepage paths. Compacting the clay layer reduces the impact of groundwater or foundation seepage on the system.

Description

Technical Field

[0001] This utility model relates to the technical field of riverbed seepage prevention construction, specifically an ecological grid geotextile bag seepage prevention construction system. Background Technology

[0002] For riverbeds with a wide seepage prevention area, ecological grid green pads plus geotextile bags filled with sand are usually used for seepage prevention construction.

[0003] For example, the ecological geogrid geobag seepage prevention construction system disclosed in patent publication number CN220132947U belongs to the field of riverbed seepage prevention construction technology. When in use, the skeleton mold is set inside the ecological geogrid geobag, which can fix the ecological geogrid geobag on the one hand and support the opening of the ecological geogrid geobag on the other hand. When filling sand and gravel, it ensures that the ecological geogrid geobag is always in an open state, which facilitates filling and construction.

[0004] The above-mentioned equipment can move the skeleton mold to the next geotextile bag for reuse after the filling is completed, which can improve efficiency and speed up the construction progress while ensuring construction quality.

[0005] However, while the above-mentioned solutions facilitate the filling of geotextiles, these conventional geotextile bags need to be placed inside an ecological grid before being stacked. Often, the stacked areas do not fit well, and the seepage prevention work is mostly achieved solely through the geotextile bags during stacking. The structure is relatively simple, and the seepage prevention performance could still be improved. Therefore, we propose an ecological geogrid geotextile bag seepage prevention construction system. Utility Model Content

[0006] One of the technical problems this application aims to solve is to effectively improve the impermeability of geotextile bags.

[0007] To address the aforementioned technical problems, this application provides an ecological geogrid geotextile bag seepage prevention construction system, comprising a ground surface and an ecological mesh body, wherein irregularly shaped geotextile bags are evenly laid within the ecological mesh body, and the irregularly shaped geotextile bags are symmetrically stacked and interlocked with each other to reduce seepage gaps; The irregularly shaped geotextile bags are provided with an impermeable transition layer at the stacking contact surface, and a biological impermeable layer is provided on the upper surface of the irregularly shaped geotextile bags to lock in moisture.

[0008] In some embodiments, in order to reduce water infiltration, the irregularly shaped geotextile bag is provided with concave and convex portions at both ends, and the concave and convex portions at the inner and outer ends can be stacked together.

[0009] In some embodiments, to improve impermeability, polyurethane sealant is injected between the irregularly shaped geobags on the same side.

[0010] In some embodiments, to further improve impermeability, the impermeable transition layer is a bentonite roll material, and the thickness of the impermeable transition layer is 2cm-3cm.

[0011] In some embodiments, in order to improve the impermeability between the ground and the ecological network, a compacted clay layer is laid on top of the ground, and the height of the compacted clay layer is 10cm-15cm.

[0012] In some embodiments, in order to immobilize a portion of the water flow, the biological impermeable layer includes nutrient soil disposed on top of the irregular geotextile stack layer to utilize plant roots to reduce surface runoff erosion.

[0013] In some embodiments, in order to improve impermeability through the water absorption and expansion of the coconut fiber blanket, a coconut fiber blanket is embedded between the irregularly shaped geobag and the nutrient soil.

[0014] This utility model has at least the following beneficial effects: 1. By using irregularly shaped geotextile bags with symmetrical stacking and interlocking of concave and convex parts at both ends, the gap between the bags is reduced structurally. Compared with traditional rectangular bags, this can reduce seepage channels by more than 30%, thereby reducing the risk of leakage from the source.

[0015] 2. The seepage-proof transition layer utilizes the water-swelling properties of bentonite to fill the tiny gaps on the contact surface of the bag, forming the first seepage barrier. The polyurethane sealant injected between the bags on the same side has high elasticity and adhesion, which can adapt to the settlement and deformation of the bags and block the lateral leakage path. Then, the bottom 10-15cm compacted clay layer serves as the base seepage prevention layer to reduce the impact of groundwater or foundation seepage on the system.

[0016] 3. The top nutrient soil, combined with the plant roots, forms a "biological cover layer." The plant roots can penetrate and reinforce the surface structure, reducing the exposure of gaps caused by surface runoff. At the same time, the transpiration of vegetation reduces the infiltration pressure of surface water. This not only solves the problem of gap leakage in traditional geotextile bag systems, but also takes into account structural stability, construction economy, and ecological sustainability.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: an ecological grid geotextile bag seepage prevention construction system, including a ground 1 and an ecological net body 2, wherein irregularly shaped geotextile bags 3 are evenly laid in the ecological net body 2, and the irregularly shaped geotextile bags 3 are symmetrically stacked and interlocked with each other to reduce seepage gaps. The irregular geotextile bags 3 are stacked with a seepage-proof transition layer 4, and a biological seepage-proof layer 5 is laid on the upper surface of the irregular geotextile bags 3 to lock in moisture.

[0021] Example 2: The irregular geobag 3 has concave and convex parts 6 at both ends. The concave and convex parts 6 at the inner and outer ends can be stacked together. It should be noted that in order to improve the impermeability of the geobag, the irregular geobag 3 adopts a composite impermeable geobag: on the basis of traditional geotextile, a layer of high-density polyethylene impermeable membrane or bentonite waterproof blanket is laminated to block water flow by utilizing the low permeability of the membrane material.

[0022] To further improve the overall impermeability of this solution, polyurethane sealant 7 is injected between the irregularly shaped geobags 3 on the same side. It should be noted that before injecting polyurethane sealant 7, the surfaces of both sides of the irregularly shaped geobags 3 should be wiped with cotton yarn to remove impurities such as mud, dust, and oil. If the surface is damp, it should be dried with a hair dryer or a dry cloth. Then, holding the glue gun, the nozzle should be aimed at the vertical gap formed by the side interlocking, and the glue should be injected evenly from the bottom up, ensuring that the glue fills the gap and slightly overflows. After the glue has initially shaped (about 5-10 minutes, adjusted according to the ambient temperature), it should be smoothed along the surface of the gap with a scraper so that the glue layer is flush with the surface of the bag. At the same time, the overflowing glue should be recycled.

[0023] The seepage-proof transition layer 4 is made of bentonite roll material, and the thickness of the seepage-proof transition layer 4 is 2cm-3cm. It should be noted that when installing the seepage-proof transition layer 4, the cut bentonite roll material needs to be laid flat on the surface of the concave and convex parts 6 of the irregular geotextile bag 3, with the edge of the roll material aligned with the edge of the convex part. Water-soluble tape is used to stick and fix the roll material to the convex part surface with the perimeter (the tape width is 3-5cm, and it is applied every 10-15cm) to prevent the roll material from shifting during the laying process. A compacted clay layer 8 is laid on top of the ground 1. The compacted clay layer 8 is 10cm-15cm high, so that the compacted clay layer 8 can block the path of water seeping upward from the base, thereby improving the impermeability.

[0024] The biological impermeable layer 5 includes nutrient soil 501, which is placed on top of the stacked irregular geotextile layers to reduce surface runoff erosion using plant roots. Coconut fiber blanket 502 is embedded between the irregular geotextile bags 3 and the nutrient soil 501. Utilizing the "reinforcing-impermeable" effect of plant roots, the roots can fill tiny gaps while reducing surface runoff erosion. The biological impermeable layer 5 is constructed by embedding coconut fiber blanket 502 between the geotextile bags. After absorbing water, it expands to seal gaps and provides a habitat for microorganisms, further enhancing impermeability through the biofilm.
