Description

Technical Field

[0001] The utility model belongs to the technical field of civil engineering and water conservancy engineering, in particular to a soil and water retaining structure, in particular to a large-scale connected reinforced geobag structure. Background Art

[0002] Geobags are woven bags filled with loose soil, rock, and construction waste. They have long been used in flood control and rescue operations or as retaining structures. In recent years, they have been increasingly used in projects such as foundation reinforcement, road subgrades, and building foundations. The construction process for geobags is simple and convenient, with low costs and minimal engineering investment. Geobags do not require the addition of any chemical reagents to reinforce foundations, resulting in less environmental impact. Compared to pile foundation construction, geobags generate less noise during construction. More importantly, geobags have a high bearing capacity. In soft soil foundations, their use can significantly increase the bearing capacity of the foundation while also offering advantages such as vibration reduction and liquefaction prevention. In cold regions, geobags filled with coarse-grained soil also provide freeze-thaw protection.

[0003] However, in some actual projects, geobags can become excessively deformed, resulting in low overall strength after stacking and the collapse of the enclosure structure, all of which hinders their effectiveness. Traditional geobags are relatively small, requiring manual handling, either individually or in simple stacks, which can be slow, especially for large-scale projects like reclamation cofferdams. Utility Model Content

[0004] In order to solve the above problems in the application of geobags, this utility model patent provides a large-scale connected reinforced geobag structure, which improves the strength of geobags, facilitates rapid hoisting and construction, improves the integrity of the stacking structure, and reduces the deformation of the enclosure structure. The purpose of this utility model is achieved through the following technical solutions:

[0005] A connected reinforced geobag structure, which is a single-layer or multi-layer stacked structure, each layer is composed of multiple (at least two) reinforced geobags filled with soil and stone connected horizontally and / or vertically; the reinforced geobag includes a bag body, a reinforcement constraint device arranged in the bag body, and a connection device connected to the reinforcement constraint device and passing through the bag body; the bag body is a rectangular woven bag, and the reinforcement constraint device is composed of two identical rectangular reinforcements crossing each other, and the upper and lower intersection points are connected by vertical reinforcements, the central axis of the vertical reinforcement is the vertical center line of the bag body, the length of the rectangular reinforcement is the diagonal of the upper and lower planes of the bag body, and the width of the rectangular reinforcement is the height of the bag body; each reinforced geobag is provided with at least two connection devices, each connection device includes a connecting belt and a flexible ring connected to the front end of the connecting belt, and the end of the connecting belt is fixedly connected to the intersection point of the rectangular reinforcement; after the connection device of a reinforced geobag passes out of the bag body, its front end is connected to the connection device of another adjacent reinforced geobag.

[0006] In a further optimization, the connection device of a reinforced geobag passes through the bag body and the flexible ring at the front end thereof is connected to the flexible ring at the front end of the connection device of another adjacent reinforced geobag through a metal quick connection ring.

[0007] Furthermore, the bag body is made of glass fiber modified polypropylene.

[0008] Furthermore, the reinforced restraint device uses plastic-coated stainless steel reinforcement.

[0009] Furthermore, the connecting belt is a nylon belt.

[0010] Furthermore, the bag body and the reinforcement restraint device are connected by sewing.

[0011] Furthermore, the upper and lower planes of the bag body are squares. After multiple bag bodies in the same layer are connected, the upper and lower planes of adjacent reinforced restraint devices form multiple connected squares.

[0012] Furthermore, the bag size is 200cm*200cm*50cm.

[0013] The advantages and beneficial effects of the utility model are:

[0014] This utility model provides a large-scale connected reinforced geobag structure. Internal reinforcement improves the strength of the geobags, and a connecting device allows for rapid lifting and installation. The geobags are connected in pairs, improving the integrity of the stacked structure and minimizing deformation of the enclosure. It is suitable for projects such as reclamation cofferdams, slope engineering, and foundation reinforcement.

[0015] Reinforced geobags are filled with soil and stone materials to form a large reinforced flexible structure. The tension of the bag body and the friction between the soil and stone materials during the stress process are used to achieve the effect of vibration reduction and energy consumption, and increase the strength of the soil and stone materials in the bag body.

[0016] Internal reinforcement improves the strength of the bag and can prevent the geobag from excessive deformation that affects its function.

[0017] The connecting device can not only connect the geobags to improve the overall strength, but also can be hoisted through the flexible lifting rings at the ends, and can be used with excavators or cranes to save manpower and improve construction efficiency. This utility model can improve the integrity of multiple geobags when working together, and the structure is simple to implement. It can be used in foundation reinforcement, slope engineering, roadbed engineering, reclamation cofferdam and other fields. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Example 1:

[0026] like Figure 2 、 3 As shown, a large-scale connected reinforced geobag structure is a single-layer or multi-layer stacked structure, each layer is composed of multiple reinforced geobags filled with soil and rocks connected horizontally and / or vertically; Figure 1 As shown, the reinforced geobag includes a bag body 1, a reinforcement constraint device 2 arranged in the bag body 1, and a connecting device 3 connected to the reinforcement constraint device 2 and passing through the bag body 1.

[0027] In this embodiment, the bag body 1 is a rectangular woven bag with a basic size of 200cm*200cm*50cm. The material of the bag body 1 is glass fiber modified polypropylene with excellent strength and durability.

[0028] like Figure 1 As shown, the reinforced restraint device 2 is composed of two identical rectangular reinforcements 21 that cross and the upper and lower intersection points are connected by vertical reinforcements 22. The central axis of the vertical reinforcement 22 is the vertical center line of the bag body 1, the length of the rectangular reinforcement 21 is the diagonal of the upper and lower planes of the bag body 1, and the width of the rectangular reinforcement 21 is the height of the bag body 1. This cross setting can support the bag body and is very stable, effectively enhancing the strength of the bag body. The reinforced restraint device in this embodiment uses plastic-coated stainless steel, which can ensure strength while preventing the reinforcement from rusting. The bag body 1 and the reinforced restraint device 2 can be more firmly connected by sewing with encrypted thread, but they can also be unsewn for easy disassembly and assembly.

[0029] In this embodiment, each reinforced geobag is provided with two connecting devices 3 for hoisting and connecting. Each connecting device 3 includes a connecting belt 31 and a flexible ring 32 connected to the front end of the connecting belt 31. In this embodiment, the connecting belt 31 is a multi-layer encrypted nylon belt.

[0030] The end of the connecting strap 31 is fixedly connected to the intersection of the rectangular reinforcement 21, which is conducive to the stability of the connection. The connecting device 3 of one reinforced geobag passes out of the bag body 1, and the flexible ring 32 at the front end of the connecting device 3 of another adjacent reinforced geobag is connected to the flexible ring 32 at the front end of the connecting device 3 of the other adjacent reinforced geobag via a metal quick connecting ring 4. The metal quick connecting ring 4 is a commercially available product and can be a quick-connection clamp or a connecting ring that is tightened by threads.

[0031] In this embodiment, Figure 3 As shown, the upper and lower planes of the bag body 1 are squares. After multiple bag bodies 1 on the same layer are connected, the upper and lower planes of adjacent reinforced restraint devices 2 form multiple connected squares, further enhancing the stability of the structure.

[0032] Geobags are reinforced with specially shaped plastic-coated stainless steel as internal reinforcement and restraints, enhancing their strength. Two connecting devices are located at the top center of each geobag, allowing for lifting and connecting adjacent geobags. During construction, flexible lifting rings on the two connecting devices allow for rapid lifting and construction. Multiple geobags can be stacked horizontally, vertically, and vertically to form the desired structure. Geobags at the same height both horizontally and vertically constitute a single layer, and each layer is connected by connecting devices, enhancing the integrity of the stacked structure.

[0033] Finally, it should be noted that the above is only used to illustrate the technical solution of the utility model and is not a limitation. Although the utility model is described in detail with reference to the preferred arrangement scheme, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
