Concrete-filled steel tube underground reservoir artificial dam body
The invention discloses a concrete-filled steel tube artificial dam body of an underground reservoir. Comprising the following steps that the underground reservoir is surveyed, and the height and width of a connection roadway, the type of surrounding coal and rock masses, the caving degree and the overall structure are determined; after the overall general situation is determined, necessary material instruments such as seamless steel pipes and joint sleeves are transported to a connection roadway to be assembled and partially welded; dam body support clamping grooves are dug according to the size; steel pipes are assembled according to the clamping grooves, ejector rods are driven into the steel pipe connecting pipe positions through the surfaces of the steel pipes, and the overall structure of the steel pipes is kept stable before grouting; after the steel pipes are assembled and integrally welded, concrete is poured through a grouting opening by using a mining hydraulic grouting pump; an electric vibrator is used for vibrating, and coal gangue mortar is used for backfilling a clamping groove part; and after the steel pipe concrete is integrally finished, welding the steel bar grid and pouring the artificial dam body. Combination of the concrete filled steel tube support and the artificial dam body in the prior art is achieved, the bearing capacity of the artificial dam body is improved, and long-term safe operation of the underground reservoir is guaranteed.
本发明公开了一种钢管混凝土地下水库人工坝体。包括以下步骤：对所述地下水库进行勘察，确定联络巷高度、宽度、周围煤岩体类型、垮落程度以及整体结构；确定整体概况后，将无缝钢管、接头套管等必要材料器械运输至联络巷进行组装、部分焊接；按尺寸挖好坝体支架卡槽；根据卡槽组装钢管，在钢管连接管位置经钢管表面打入顶杆，维持注浆前钢管整体结构稳定；钢管组装、整体焊接完成后，用矿用液压注浆泵经注浆口灌注混凝土；用电动式振捣器振捣，在卡槽部分用煤矸石砂浆回填；钢管混凝土整体完成后，焊接钢筋网格，浇筑人工坝体。本发明实现了现有技术中钢管混凝土支架和人工坝体的结合，提高了人工坝体的承载能力，保障了地下水库长期安全运行。
