Description

Technical Field

[0001] The present invention relates to the technical field of civil engineering and water conservancy projects, and in particular to an anti-seepage curtain earthquake-resistant structure based on flexible energy dissipation and a construction method thereof. Background Art

[0002] An anti-seepage curtain is an engineering structure used to prevent or control the flow of groundwater, and is mainly used in water conservancy, civil engineering, environment and other fields. Its core function is to form a low-permeability barrier to reduce or block the leakage of water bodies. In recent years, earthquakes have occurred frequently around the world, causing serious damage to anti-seepage curtains in water conservancy projects, underground structures and environmental facilities, and triggering a series of social problems. Under the action of earthquakes, traditional rigid anti-seepage curtains (such as concrete anti-seepage walls, grouting curtains, etc.) are prone to brittle cracking, joint dislocation and soil-structure interaction failure, leading to disasters such as dam leakage, foundation pit water gushing, and tailings pond pollutant leakage, which not only threaten the safety of the project, but also cause huge economic losses and environmental pollution. Therefore, there is an urgent need to develop a new anti-seepage curtain structure and construction method that has both earthquake resistance and anti-seepage functions.

[0003] The existing anti-seepage curtain structure and construction plan have the following problems:

[0004] (1) Existing anti-seepage curtain materials mainly rely on rigid materials such as concrete and cement slurry, which generally have low tensile strength. When subjected to earthquake shear waves, the materials are prone to brittle failure and form through-cracks, resulting in a sudden increase in the permeability coefficient, which seriously threatens the safety of the project. These materials have a high elastic modulus and are difficult to adapt to foundation deformation or fault movement. Traditional solutions such as increasing the reinforcement ratio or joint waterstops still have problems such as steel bar slippage and joint failure.

[0005] (2) The existing anti-seepage curtain structure design has the technical defect of "focusing on anti-seepage and neglecting earthquake resistance". Many patents consider the anti-seepage effect of anti-seepage curtains and improve the anti-seepage performance through different technical means. Among them, there is a patent that forms a combined anti-seepage curtain by setting up multiple layers of anti-seepage. Although this greatly improves the anti-seepage performance of the anti-seepage curtain, there is a risk of the curtain being damaged due to its high rigidity under the action of an earthquake.

[0006] (3) The existing curtain construction scheme mainly adopts the traditional grouting construction technology, which is difficult to adapt to the current requirements of efficient construction. For example, when using the "sequential intensification" construction method, it is necessary to strictly wait for the slurry in the previous hole to initially set before the next sequence of construction can be carried out, which will seriously affect the progress of the project. Summary of the Invention

[0007] The purpose of the present invention is to provide an anti-seismic structure and construction method of an anti-seepage curtain based on flexible energy dissipation, so as to solve the problem mentioned in the above background technology that the anti-seismic curtain in the existing technology is not strong and is prone to brittle cracking, and to improve the anti-seismic ability and construction efficiency of the anti-seepage curtain.

The prefabricated assembled curtains are assembled using lifting equipment.

[0050] The upper curtain 1, the middle curtain 2, the lower curtain 3, the cast-in-place concrete interlayer 10 and the cast-in-place concrete upper layer 5 are made of high-ductility fiber concrete materials. The fiber reinforcement improves the structural ductility, structural toughness and crack resistance. The flexible energy dissipation layer 4 is a rubber asphalt composite material, which has both flexibility and rigidity to achieve energy dissipation and recovery functions.
