Description

TECHNICAL FIELD

[0001] The present application relates to the construction technology field of artificial lake anti-seepage structure, in particular to a high-permeability deep-water artificial lake anti-seepage composite structure construction method based on Ansys+BIM technology. BACKGROUND

[0002] The biggest problem encountered in the actual construction of artificial lakes is anti-seepage. At present, the anti-seepage scheme of the artificial lake foundation mostly adopts the bentonite waterproof blanket technology. Water leakage of the artificial lake will reduce economic benefits, increase the operation cost of the management department, and also cause the lake wall to fall off, affecting the aquatic plants and animals in the lake body and the landscape. Anti-leakage is a relatively complex project in the construction of artificial lakes and is a problem that is often encountered. Therefore, great attention should be paid to it in the construction of artificial lakes and appropriate treatment measures should be taken. The bentonite waterproof blanket is composed of geotextile and bentonite by needling, bonding or sewing process. The bentonite can absorb several times the volume of water and expand to more than twenty times its own volume. However, the static water pressure of the bentonite waterproof blanket is large in high-permeability deep-water artificial lakes, which is easy to cause extrusion deformation. At the same time, during the laying of the bentonite waterproof blanket, the waterproof blanket is easy to be damaged by early hydration and contact with the ground during large-area laying. Therefore, it is required to do a good job in preparation and control during the process, and through reasonable technical means and organization arrangement, the bentonite waterproof blanket can be laid in place. The BIM technology provides model support, and the Ansys technology provides finite element analysis. Through the combination of the two, the problems in the construction process of laying the bentonite waterproof blanket in high-permeability deep-water artificial lakes are solved, and sufficient technical support is provided. SUMMARY

[0003] (I) Technical problems solved

[0004] In view of the deficiencies of the prior art, the present application provides a high-permeability deep-water artificial lake anti-seepage composite structure construction method based on Ansys+BIM technology, which solves the following technical problems:

[0005] The static water pressure of the bentonite waterproof blanket is large in high-permeability deep-water artificial lakes, which is easy to cause irregular deformation of the waterproof blanket. In the construction process, due to the poor lap joint or the non-compactness of the upper and lower base layers, the bentonite waterproof blanket expands after being wetted, causing the generation of gaps and further leading to water seepage.

[0006] (II) Technical scheme

[0007] To achieve the above purpose, the present application is implemented by the following technical scheme: a high-permeability deep-water artificial lake anti-seepage composite structure construction method based on Ansys+BIM technology.

[0008] (1)High permeability, deep water level artificial lake water body on the bentonite waterproof blanket hydrostatic pressure is larger, prone to irregular deformation of waterproof blanket, due to the lap in place or the upper and lower base is not dense, bentonite waterproof blanket after water swelling caused by the production of cracks and then lead to water seepage. By optimizing the construction method of waterproof blanket, increase the waterproof blanket lap joint tensile properties, can solve this problem.

[0009] (2) using related BIM software to build high permeability, deep water level artificial lake BIM model. The BIM model is imported into the related Ansys software for finite element analysis. Adjust the three-dimensional model of artificial lake with different depths and different terrains on the BIM model, focusing on the joints at different elevations and special parts. The BIM model has visualization and parameterization functions. Ansys performs finite element analysis on the model to analyze the compression resistance of the composite waterproof blanket. Based on the results of the finite element analysis, the BIM model is adjusted to continuously optimize the construction method of the composite waterproof blanket. The output parameters, design drawings, and three-dimensional model must be confirmed by experts before production and processing. This scheme can fully demonstrate the theoretical performance of the composite waterproof blanket and achieve the purpose of optimizing the design.

[0010] (3) Compared with the traditional waterproof blanket construction method, the construction method of the impermeable composite waterproof blanket requires higher waterproof blanket laying method and technical personnel level. Waterproof blanket construction is a paving operation, which can be dynamically adjusted on site, but the range is limited. Paving workers need to have certain skill level to construct and must do accurate positioning and layout work. Through three-dimensional animation simulation of the entire construction process and video technology briefing, the workers' ability to respond during construction can be continuously improved. By simulating different scenarios, the actual technical parameters and allowable deviation range during construction are obtained to provide technical support for waterproof blanket paving.

[0011] (4) During the waterproof blanket paving process, the paving construction is subject to the lake bottom terrain and joint treatment. The high permeability and deep water level water body has a large static pressure on the waterproof blanket, which is easy to cause the generation of gaps and affect the impermeability of the waterproof blanket. Make full use of the advantages of Ansys+BIM technology to plan and arrange the impermeable composite waterproof blanket paving in detail. Simulate and analyze the entire construction and installation process to solve related problems such as waterproof blanket paving deformation and gap generation.
