Description

Technical Field

[0001] This invention relates to the field of flood control and disaster relief equipment and flexible water-retaining equipment structural design technology, and particularly to a modular connection and anchoring structure for a water-filled bag dike. Background Technology

[0002] Water-filled bag dikes are flexible, temporary water-retaining devices that use water as the primary filling medium. They are widely used in scenarios requiring the rapid formation of continuous water barriers, such as dike overflow emergency response and urban flooding emergencies. For longer water barriers, the use of multi-section water-filled bag units is more convenient for transportation, deployment, and partial replacement than a single long bag, and has become an important development direction for emergency flood control equipment.

[0003] However, in existing assembly methods, adjacent bags often rely on external connections such as manual overlapping, rope binding, outer sleeves, or hook-and-loop fasteners. The integration between the connecting components and the bag body is insufficient, on-site alignment and fixing procedures are cumbersome, and the contact area at the joints is limited, easily leading to weak points such as end misalignment, edge warping, and water seepage at the seams. Furthermore, after the bags are filled with water, their weight increases, accompanied by sinking, outward expansion, and bulging deformation. If reinforcement relies solely on external netting, temporary binding, or installing ring hoops after filling, problems often arise such as difficulty in covering and tensioning, insufficient fit between the reinforcement components and the bag body, and unclear anchoring force transmission, making it difficult to stably limit bag deformation and overall slippage. Therefore, this invention proposes a modular connection and anchoring structure for water-filled bag dikes. By setting skirt-type connecting components at the ends of the bags and combining surface connection units with point connection units, along with ring hoop components and anchors, each bag section possesses the ability for rapid assembly, seepage-proof overlapping, and limited anchoring. This improves emergency response efficiency while enhancing the continuity and overall stability of the water-retaining line. Summary of the Invention

[0004] The purpose of this invention is to provide a modular connection and anchoring structure for water-filled bag dikes.

[0005] To achieve the above objectives, the present invention is implemented according to the following technical solution: A modular connection and anchoring structure for a water-filled bag dike includes a bag body, an end connection component, a ring assembly, an anchoring component, and a deformable water-stopping component. The end connection component is located at the upstream water-blocking side of the bag body and includes an overlapping skirt, a surface connection unit, and a point connection unit. The ring assembly covers the outer periphery of the bag body. The anchoring component is connected to the ring assembly to fix the ring assembly to the target surface. The deformable water-stopping component is located at the bottom or bottom edge of the bag body.

[0006] Furthermore, the top of the bag is provided with a water filling valve and a vent valve, and the lower end of the back water side is provided with a drain valve and an air filling valve; the water filling valve is used to fill the bag with water, the vent valve is used to expel air from the bag during the water filling process, the air filling valve is used to inflate the bag before filling with water, and the drain valve is used to drain the water from the bag.

[0007] Furthermore, the overlapping skirt extends outward from the end of the bag body to cover the end of another bag body when adjacent bags are connected, forming a planar anti-seepage overlap on the upstream water-blocking side.

[0008] Furthermore, the point connection unit is a point-type connector arranged continuously or at intervals along the height direction of the bag, and is disposed on the outside of the surface connection unit or covering the surface connection unit.

[0009] Furthermore, the surface connection unit may be in the form of hook and loop fasteners, including a hook-and-loop connection layer and a fleece connection layer; the hook-and-loop connection layer is disposed at the end of the overlapping skirt hem, and the fleece connection layer is disposed at the end of the adjacent bag body; the hook-and-loop connection layer and the fleece connection layer form a relatively fitted surface.

[0010] Furthermore, the point connection unit may be in the form of metal fasteners, including metal buckles and metal loops; the metal buckles and metal loops are arranged continuously or at intervals along the height direction of the bag body, and are used to lock the ends of adjacent bags after the surface connectors are attached.

[0011] Furthermore, the hoop assembly includes a hoop band and an anchor foot; the anchor foot is disposed on the side or bottom of the hoop band and connected to the anchor assembly.

[0012] Furthermore, the anchoring assembly includes one or more of the following: expansion bolts, ground anchors, anchor plates, ballast connectors, or temporary clamps.

[0013] Furthermore, the target surface can be either a rigid embankment top surface or an earthen embankment top surface.

[0014] Furthermore, multiple bags are connected in sequence through the end connection assembly and fixed to the target surface by the ring assembly and anchoring assembly to form a continuous water-retaining sub-dike.

[0015] Furthermore, the deformable water-stopping component adopts EPDM foam strips, closed-cell foam sealing strips, or flexible anti-seepage pressure strips.

[0016] The beneficial effects of this invention are: This invention is a modular connection and anchoring structure for water-filled bag dikes. Compared with the prior art, this invention has the following technical advantages: This invention enables modular and rapid assembly of a single water-filled bag by pre-installing the end connection component at the end of the bag body, reducing the need for on-site additional operations such as sleeve installation, binding, and repeated alignment. The present invention forms a surface bonding by using surface connection units and point connection units, which can increase the bonding area of ​​adjacent bag ends and reduce the risk of seam curling, local misalignment and water seepage channels. The present invention improves the resistance to end misalignment at the connection by providing tensile strength through the point connection unit, and avoids the problem of single hook and loop fasteners being sheared and peeled off or single point fasteners having large gaps. This invention, through the cooperation of the ring assembly and the anchoring assembly, can limit the sinking, outward expansion and lateral bulging deformation of the bag after it is filled with water, thereby improving the overall stability of the bag and the reliability of the anchoring. This invention improves the adaptability of bag forming, venting, air filling, draining and bottom waterproofing components through the structural combination of water filling valve, venting valve, air filling valve, draining valve and bottom deformable water-stopping component.

Detailed Implementation

[0018] The present invention will be further described below through specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.

[0019] like Figure 1As shown, the present invention discloses a modular connection and anchoring structure for a water-filled bag dike, comprising a bag body 1, an end connection assembly 2, a ring assembly 3, an anchoring assembly 4, and a deformable water-stopping assembly 5. The bag body 1 is used to form a temporary water-blocking section after being filled with water. The top of the bag body 1 is provided with a water filling valve 1-1 and an air vent valve 1-2, which can be used to inject water into the bag body and expel air from the bag body during the water filling process. The lower end of the backwater side of the bag body 1 is provided with a drain valve 1-3 and an air inflation valve 1-4, which can be used to inflate the bag body into shape before water filling and to drain the water from the bag body. The inflation valves 1-4 can also be connected to siphon pipes to improve the bag's emptying efficiency; the end connection component 2 is set at the upstream water-blocking end of the bag 1; the ring assembly 3 covers the outer periphery of the bag 1; the anchoring component 4 is used to fix the ring assembly 3 to the embankment or foundation structure; the bottom deformable water-stop component 5 is set at the bottom or bottom edge of the bag 1. When there are local unevenness on the top of the embankment or the ground, the bottom deformable water-stop component 5 can be compressed and deformed as the bag 1 is pressed, reducing the slight leakage channel between the bottom of the bag 1 and the foundation surface.

[0020] like Figure 2 The diagram shows a composite connection structure with point-to-surface bonding at the end. The end connection component 2 includes an overlapping skirt 2-1, a surface connection unit (hook-to-surface connection layer 2-2 and fleece connection layer 2-3), and a point connection unit (metal buckle 2-4 and metal buckle ring 2-5). The overlapping skirt 2-1 is located on the upstream water-blocking side and covers the outer side of the end of another bag when adjacent bags are connected. The hook-to-surface connection layer 2-2 and fleece connection layer 2-3 are respectively set on the relative contact surfaces of adjacent bags and form a surface connection after pressing. The metal buckle 2-4 and metal buckle 2-5 are arranged at intervals along the height direction of the bag 1 to form a mechanical lock after the surface is bonded.

[0021] like Figure 3 The diagram shows the structure of the hoop assembly and anchoring assembly. The hoop assembly 3 includes a hoop band 3-1 and an anchor foot 3-2. The anchoring assembly 4 can be one or more of the following: expansion bolts, ground anchors, anchor plates, ballast connectors, or temporary clamps. The hoop band 3-1 covers the outer periphery of the bag body 1. The anchor foot 3-2 is located on the side or bottom of the hoop band 5. The anchoring assembly 4 passes through the fixing hole on the anchor foot 3-2 and connects to the embankment surface or foundation surface. The hoop assembly 3 can be installed before the bag body 1 is filled with water and is tightly attached to the outer surface of the bag body 1 after the bag body 1 is filled with water. It is used to limit the outward expansion, sinking, and lateral bulging deformation of the bag body 1.

[0022] Assemble the above components to obtain a product example of a modular connection and anchoring structure for a water-filled bag dike, such as... Figure 4 As shown, a structural comparison is made of different end connection methods, such as... Figure 5 As shown; for a detailed comparison of the connection methods, structures, and materials, please refer to Table 1 below; Under the condition that a single bag section is 10m long, 2m high, and 5m wide, a structural and material comparison is made between sleeve connection, hook-and-loop connection, and the combined connection of the present invention: If the sleeve width of the sleeve connection is 2m, the area of ​​waterproof covering material at a single connection is approximately 10m². 2 If the width of the overlapping skirt in this invention is 0.5m, then the coverage area of ​​a single connected skirt is approximately 2.5m. 2 The area of ​​the waterproof covering material connected by the sleeve is about 25%; at the same time, the present invention adds hook and loop fastener connectors and about 5 sets of metal fasteners to improve the fit and continuity and anti-misalignment ability of the connection. In the embodiment with a bag height of 2m, hook and loop fasteners are added, and 5 sets of metal buckles and metal rings are arranged along the height direction to improve the continuity of the fit and the ability to resist misalignment at the connection. A certain distance is reserved at the top and bottom, and the spacing in the middle is about 0.4m. The hook and loop fasteners can be set as one or two continuous strips, or they can be set in sections according to the stress conditions. The width of the overlapping skirt can be about 0.5m, which is used to control the amount of connecting material while ensuring the waterproof and fitting area. Table 1. Comparison of materials used in structures with different end connection methods

[0023] Furthermore, the present invention does not limit the cross-sectional shape of the bag, the material of the bag, and the specific dimensions of the end connecting components. Depending on the water-blocking height and bag specifications, the overlapping skirt can be continuously or partially set along the height direction of the bag, the hook and loop fastener connectors can be continuously or segmented, the number of metal fasteners can be adjusted according to the connection height and water pressure conditions, and one or more sets of ring assemblies can be set along the length direction of the bag.
