AI Technical Summary
The existing segmented dams suffer from long construction and dismantling periods and high costs, making them particularly inconvenient to use in landfills, tailings ponds, and sewage treatment plants.
Geomembrane is processed into membrane bags, and the gas volume is controlled through inflation and deflation interfaces. The expandability of the geomembrane is used to form segmented dams, which are then connected to the pool body via hot-melt joints, enabling rapid construction and dismantling.
It enables the rapid construction and dismantling of segmented dams, reducing construction time and costs, and is suitable for zonal filling of brine of different concentrations.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of segmented dam technology, and in particular to a geomembrane inflatable segmented dam. Background Technology
[0002] In existing landfills, tailings ponds, sewage treatment plants, and other structures containing liquids, if the underlying impermeable layer in some areas is damaged and requires repair, a dividing dam is often constructed between the repaired and unrepaired areas to block the flow of liquid in the unrepaired area, facilitating construction work in the repaired area. Similarly, large-area brine ponds require the filling of brine of varying concentrations, necessitating the construction of dividing dams to divide the pond into multiple areas. Currently, these dividing dams are typically constructed using earth filling or bagged sand, resulting in long construction and dismantling periods and high costs. Utility Model Content
[0003] To address the problems of long construction periods and high costs in the construction and dismantling of segmented dams in existing technical solutions, this utility model provides a geomembrane inflatable segmented dam.
[0004] This utility model provides the following technical solution: a geomembrane inflatable dividing dam, comprising a geomembrane bag, the geomembrane bag comprising a rolled geomembrane, a heat-fused seam disposed at the junction of the two sides of the rolled geomembrane, gas filled inside the rolled geomembrane, and an inflation / deflation port, the rolled geomembrane being provided with a connecting part for heat-fused connection with the bottom membrane of the pool body, the inflation / deflation port comprising a float disposed inside the geomembrane bag, the float being inserted with an interface pipe, the interface pipe extending to the outside of the geomembrane bag and heat-fused to the rolled geomembrane, the interface pipe being provided with a valve, and the float being further provided with an inflation hole communicating with the interface pipe and the inside of the geomembrane bag.
[0005] Preferably, at least two heat-fused joints are provided at the junction of the two sides of the rolled geomembrane.
[0006] Preferably, the float is wrapped with a geomembrane, the geomembrane is thermally fused to the rolled geomembrane, and the geomembrane is provided with a vent hole communicating with the air hole.
[0007] Preferably, the rolled geomembrane and the interface pipe are both made of high-density polyethylene, and the float is a foam block.
[0008] The beneficial effects of this utility model are: the geomembrane is processed into a geomembrane bag, which is then heat-fused to the bottom membrane of the pool. The inflation and deflation operations are completed through the inflation and deflation interface. After inflation, the volume increases rapidly, which acts as a dividing dam to divide the pool into two parts. The dam is formed with high efficiency, short time and low cost. After deflation, the volume shrinks, and most of the dam sinks to the bottom of the water under the action of gravity. The brine pool is then reconnected as one, and large volumes of brine can be filled again. Attached Figure Description

[0012] The embodiments of this utility model will be described in more detail below with reference to the accompanying drawings and reference numerals, so that those skilled in the art can implement them after reading this specification. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.
[0013] This invention provides a geomembrane inflatable segmented dam, comprising a geomembrane bag 10, the bottom of which is thermally fused to the bottom membrane of a brine pool, and both ends of which are thermally fused to the sidewall membranes of the brine pool. When filled with gas 14, the bag rapidly increases in volume to form a segmented dam, dividing the brine pool into two parts, which can be filled with different types of brine. After deflating, the volume shrinks, and under gravity, most of the dam body sinks to the bottom, reconnecting the brine pool and allowing for the filling of large volumes of brine again. Compared with existing segmented dams, the inflation and deflation operations are simple, the dam forming efficiency is high, the construction period is short, and the cost is low.
[0014] Please refer to Figure 1 , 2 The geomembrane bag 10 includes a rolled geomembrane 11. After the geomembrane is rolled into a roll, its two ends are joined by heat fusion to form a heat-fused seam 12. The heat-fused seam 12 extends to both ends of the rolled geomembrane 11, sealing the rolled geomembrane 11 to form a bag-like structure. Preferably, there are two heat-fused seams 12 to enhance the sealing performance. The rolled geomembrane 11 uses its outwardly extending side as a connecting part 13, which is heat-fused to the bottom membrane 20 of the pool to form a single-track extrusion seam. The rolled geomembrane 11 can be made of high-density polyethylene (HDPE).
[0015] The geomembrane bag 10 is also equipped with an inflation / deflation port for filling or releasing gas 14. The inflation / deflation port includes a float 15 located inside the geomembrane bag 10, with a geomembrane covering the float 15. The geomembrane is thermally fused to the rolled geomembrane 11, thus fixing the float 15 in place. The float 15 floats on the liquid surface for easy inflation / deflation operations and can be made of foam blocks. An interface pipe 16 is inserted into the float 15, and the interface pipe 16 is equipped with a valve, which is opened during inflation / deflation. The interface pipe 16 extends to the outside of the geomembrane bag 10 and is thermally fused to the rolled geomembrane 11 to form a seal. The float 15 also has an inflation hole, and the geomembrane outside the float 15 also has a vent hole communicating with the inflation hole, connecting the interface pipe 16 to the inside of the geomembrane bag 10. Both the geomembrane and the interface pipe 16 can be made of high-density polyethylene (HDPE), and the gas 14 is generally air.
[0016] In structures such as landfills, tailings ponds, and sewage ponds, this utility model can also be used to form a dividing dam by thermally fusing it with the bottom membrane of the pond.
[0017] The above describes one or more embodiments of this utility model in a relatively specific and detailed manner, but it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
