Description

Technical Field

[0001] The invention relates to the fields of building construction and municipal construction, and more specifically to a new type of artificial lake bentonite anti-seepage structure and a construction method. Background Art

[0002] Currently, most artificial lakes use concrete bottom slabs for anti-seepage structures. However, with the rise of environmental protection and low-carbon concepts, its problems have become more prominent. Concrete production has high carbon emissions, complex construction, long cycles, and high resource and energy consumption. In addition, the closed isolation layer it constructs cuts off the ecological connection between the lake and the surrounding area, hindering material exchange and energy circulation, affecting the integrity and sustainability of the ecosystem, such as limiting nutrient exchange between organisms and weakening the ecological regulation function of the lake. Summary of the invention

[0003] In response to the above problems, a new type of bentonite anti-seepage structure came into being. Bentonite swells when it comes into contact with water to form a dense anti-seepage layer. It has a simple construction process, a short cycle, low energy consumption and resources, and low carbon emissions, which meets the requirements of low-carbon environmental protection. At the same time, the structure will not completely block the ecological interaction between the lake and the surrounding area, and can maintain a certain ecological connection, making the artificial lake ecosystem more dynamic and stable, and has great application potential in the construction of artificial lakes. Therefore, the present invention provides a new type of bentonite anti-seepage structure for artificial lakes and a construction method.

[0004] The technical solution of the present invention is as follows:

[0005] A new type of bentonite anti-seepage structure for an artificial lake comprises a bentonite layer, a bottom geotextile and an upper geotextile. The bentonite layer is laid on the bottom geotextile, and the upper geotextile is laid on the bentonite layer. The bottom geotextile is laid on a plain soil layer, and planting soil is laid on the upper geotextile.

[0006] The specifications of the bottom geotextile and the upper geotextile are: 3mm thick, 250g / ㎡.

[0007] The bentonite layer has a thickness of 300 mm and a weight of 5 kg / ㎡.

[0008] A construction method for a new type of artificial lake bentonite anti-seepage structure comprises the following steps:

[0009] S1. Use plain soil to compact the original ground;

[0010] S2. Lay the bottom layer of geotextile after compaction;

[0011] S3. Lay bentonite on the bottom geotextile;

[0012] S4. Lay the upper geotextile on the bentonite;

[0013] S5. Spread planting soil on the upper geotextile.

[0014] The bentonite is laid with a thickness of 300 mm.

[0015] Technical effects and advantages of the present invention:

[0016] 1. The present invention uses bentonite to replace the concrete base plate, which is convenient for construction, simple in process, saves time and effort, and improves construction efficiency;

[0017] 2. Environmentally friendly and low-carbon, with low energy consumption and carbon emissions, in line with environmental protection needs;

[0018] 3. Eco-friendly, maintaining the ecological connection between the lake and the surrounding area, and maintaining the integrity and stability of the ecosystem;

[0019] 4. It has wide adaptability and is suitable for artificial lakes of different sizes, shapes and geological conditions, providing a universal and reliable anti-seepage solution for their construction, and promoting technological progress and sustainable development in the industry.

[0026] Embodiment 2

[0027] When implementing the new bentonite structure, the construction steps are: compacting the plain soil → laying geotextile → laying 300mm thick bentonite → laying geotextile → laying planting soil. The present invention utilizes the water-expanding characteristics of bentonite, supplemented by geotextile to constrain the bentonite, and then utilizes the pressure of the upper water to achieve the anti-seepage effect of replacing the concrete base plate.
