Abstract
Description
Technical Field
[0001] This utility model relates to the field of estuary management technology, specifically to a diversion dike with mother-daughter bags and dike core structure. Background Technology
[0002] Diversion dikes are important structures in water conservancy projects used to smoothly guide or constrain water flow. Their functions cover multiple fields such as flood control, sand control, navigation protection, and ecological management. In the core of the diversion dike with a geotextile structure, triangular gaps are generated at the edges of each layer of geotextile. Small sandbags are often used to fill these gaps to form the designed slope.
[0003] Currently, conventional technologies use small sandbags to fill these gaps. However, the sandbags need to be filled manually and transported to the construction area by barge before being manually filled. This process is time-consuming, labor-intensive, and has low overall efficiency. Manually filling triangular gaps in the first to third underwater layers is extremely difficult, and stone filling is often necessary, resulting in low construction efficiency and insufficient applicability.
[0004] Based on this, this utility model designs a diversion embankment mother-daughter bag and embankment core structure to solve the problems of low construction efficiency and insufficient applicability in filling the gaps at the edge of the diversion embankment core of the above-mentioned diversion embankment mold bag. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a diversion dike mother-daughter bag and dike core structure.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a diversion dike mother-daughter bag and dike core structure, including a mother bag, a seam line, a first daughter bag, a second daughter bag, a sand inlet, and an auxiliary seam line. The mother bag is symmetrically provided with seam lines on both sides, and the seam lines separate the first daughter bag and the second daughter bag on both sides of the mother bag. Multiple sand inlets are symmetrically reserved at the two seam lines, and the sand inlets are connected by a separate auxiliary seam line.
[0007] As a preferred embodiment of this utility model, the seam line between the mother bag and the first daughter bag and the seam line between the mother bag and the second daughter bag are both located in the upper middle part of the edge of the mother bag.
[0008] As a preferred technical solution of this utility model, the seam line adopts a folded seam form and the main seam line is interrupted when the reserved sand inlet is encountered during the sewing process.
[0009] As a preferred technical solution of this utility model, the distance between the multiple sand inlets reserved on the seam line is 6 to 8 meters, and the width of the sand inlet is about 50 centimeters.
[0010] As a preferred technical solution of this utility model, the mother bag, the first daughter bag and the second daughter bag are made of polypropylene woven fabric and are filled with sea sand from the project area.
[0011] Based on the above-mentioned core structure of the diversion dike mother and daughter bags, the dike core is formed by stacking diversion dike mother and daughter bags of different sizes. Geotextile is laid on the outside of the dike core, and there is a triangular gap between the geotextile and the dike core. A cushion stone is laid on the outside of the geotextile, and a protective layer is laid on the outside of the cushion stone.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model designs a novel "mother-daughter bag" dike core structure, cleverly utilizing the daughter bag to effectively fill the gaps at the edge of the mother bag. This avoids the problems of traditional small sandbags being unable to be smoothly dumped in harsh sea conditions, the time-consuming and labor-intensive dumping process, and the small sandbags being easily swept away or lost by waves. This structure can increase the filling rate of the gaps at the edge of the dike bag from about 15% to about 70% under harsh sea conditions. Moreover, the construction operation is simple, significantly improving the forming quality of the dike core structure. It can effectively reduce costs, simplify procedures, shorten the construction period, and improve construction reliability. The implementation effect is significant, solving the efficiency and cost problems of filling the gaps at the edge of the dike bag, and has good practicality and promotion value.

[0015] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0016] Example Please see Figures 1-5 The present invention provides the following technical solution: a diversion dike mother bag and dike core structure, including a mother bag 1, a seam line 2, a first daughter bag 3, a second daughter bag 4, a sand inlet 5 and an auxiliary seam line 6. The mother bag 1 is symmetrically provided with seam lines 2 on both sides. The seam lines 2 separate the first daughter bag 3 and the second daughter bag 4 on both sides of the mother bag 1. Multiple sand inlets 5 are symmetrically reserved at the two seam lines 2. The sand inlets 5 are connected by a separate auxiliary seam line 6.
[0017] By using the sand inlet 5 reserved on the aforementioned seam line 2, after the mother bag 1 is filled, the auxiliary seam line 6 used to sew the sand inlet 5 can be removed to fill the first sub-bag 3 and the second sub-bag 4 on both sides of the mother bag 1. The triangular gap is filled by the sub-bags, which simplifies the process, shortens the construction period, and improves the efficiency of filling the gaps at the edge of the mold bag.
[0018] The seam 2 between the mother bag 1 and the first daughter bag 3 and the seam 2 between the mother bag 1 and the second daughter bag 4 are both located in the upper middle part of the edge of the mother bag 1.
[0019] The seam 2 adopts a folded seam form and the main seam is interrupted when it encounters the reserved sand inlet 5 during the sewing process.
[0020] The spacing between the multiple sand inlets 5 reserved on the joint line 2 is 6 to 8 meters, and the width of the sand inlet 5 is about 50 centimeters.
[0021] The mother bag 1, the first daughter bag 3, and the second daughter bag 4 are made of polypropylene woven fabric and are filled with sea sand from the project area.
[0022] The core structure of the present invention includes a core formed by stacking and layering dike mother and daughter bags of different sizes. Geotextile 8 is laid on the outside of the core. There is a triangular gap 7 between the geotextile 8 and the core. A cushion stone 9 is laid on the outside of the geotextile 8. A protective layer 10 is laid on the outside of the cushion stone 9.
[0023] By using sea sand from the project area to fill the mother and daughter bags, costs can be reduced and construction operations can be simplified.
[0024] The working principle and usage process of this utility model are as follows: The mother and daughter bags are made of polypropylene woven geotextile and sewn together to form a large bag. Then, according to the calculated size of the mother and daughter bags, a partition line 2 is added to each side of the mother bag 1 to separate the mother bag 1 from the first daughter bag 3 and the second daughter bag 4. The mold bag is filled by a small cutter suction boat that transports sea sand into the mother bag 1 through a pump pipe. After the mother bag is basically formed, the auxiliary seam line 6 used to sew the sand inlet 5 is removed, thereby connecting the mother bag 1 with the first daughter bag 3 and the second daughter bag 4. The sand in the mother bag 1 flows into the first daughter bag 3 and the second daughter bag 4 to fill them. The first daughter bag 3 and the second daughter bag 4 effectively fill the triangular gaps at the edge of the mother bag 1, which solves the problems of construction difficulties, high construction costs and low construction efficiency in the traditional diversion dike mold bag edge gap filling.
[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
