Underground reservoir artificial dam body and construction method thereof
The invention provides an underground reservoir artificial dam body and a construction method thereof. The method comprises the steps that firstly, a first groove and a second groove are formed in reserved coal pillars on the two sides of a dam foundation of the artificial dam body correspondingly; secondly, a foundation trench is excavated in the dam foundation in the direction from the first groove to the second groove; thirdly, quantitative water storage argil is evenly laid in the foundation trench and tamped, and waterproof gel is smeared on the inner wall of the first groove and the inner wall of the second groove, the interior of the foundation trench and the top wall of the goaf above the foundation trench; and fourthly, the artificial dam body is constructed in the foundation trench in the direction from the first groove to the second groove. According to the technical scheme, the bottom of the dam foundation is paved through the water storage clay, the water storage and water insulation functions of the dam foundation can be improved, and seepage of the dam foundation is prevented; and the sealing performance of the connecting position of the dam body and the coal pillar can be improved by smearing and anchoring the connecting position of the groove with the waterproof gel.
本发明提供了一种地下水库人工坝体及其建造方法，该方法包括：步骤一、在所述人工坝体的坝基两侧的预留煤柱上分别开设出第一凹槽与第二凹槽；步骤二、沿所述第一凹槽至所述第二凹槽的方向，在所述坝基上开挖出基槽；步骤三、在所述基槽中均匀铺垫定量的蓄水陶土并捣实，在所述第一凹槽与所述第二凹槽的内壁上、所述基槽中以及所述基槽上方的采空区顶壁上涂抹防水凝胶；步骤四、沿所述第一凹槽至所述第二凹槽的方向，在所述基槽中构筑出所述人工坝体。基于本发明的技术方案，通过蓄水陶土对坝基底部的铺垫，可以提高坝基的蓄水和隔水功能，防止坝基渗流；通过防水凝胶对凹槽连接处的涂抹、锚固，可提高坝体与煤柱连接处的密封性。
