High-pressure water channel prefabricated reinforced concrete sandwich steel plate lining structure and construction method thereof
The invention discloses a prefabricated reinforced concrete sandwich steel plate lining structure for a high-pressure water channel and a construction method. The prefabricated reinforced concrete sandwich steel plate lining structure for the high-pressure water channel comprises a steel plate, reinforcing steel bars, a reinforced concrete barrel shell, gaskets, surrounding rock, cattle ears, reserved grooves, cattle ear reserved holes, water passing channels and annular water passing holes. The gasket is a semi-hollow cavity made of an elastic material, is mounted on the outer sides of the steel plate and the reinforced concrete barrel shells, and can expand after being filled with water in an environment with high internal water pressure, so that the reinforced concrete barrel shells on the two sides are tightly extruded; the cattle ears and the steel plate are of an integral structure and are used for hoisting and transporting the prefabricated lining; the construction method comprises the steps of key component manufacturing, assembling before pouring, reinforced concrete barrel shell pouring, gasket installing and grouting. The purpose of rapid and safe lining of structures such as the pumped storage power station high-pressure water channel vertical shaft can be achieved, and the construction speed of the high-pressure water channel is increased while the safety of the high-pressure water channel in the whole life cycle is guaranteed.
本发明公开了一种高压水道预制钢筋混凝土夹心钢板衬砌结构及施工方法，所述高压水道预制钢筋混凝土夹心钢板衬砌结构包括钢板，钢筋，钢筋混凝土筒壳，垫片，围岩，牛耳，预留槽，牛耳预留孔，过水通道，环状过水孔；所述的垫片为弹性材料半空腔体，安装在钢板和钢筋混凝土筒壳的外侧，可在高内水压力的环境下充水产生膨胀，使两侧的钢筋混凝土筒壳紧密挤压；所述的牛耳与钢板为整体结构，用于预制衬砌的起吊运输；所述的施工方法包括制作关键构件、浇筑前组装、钢筋混凝土筒壳浇筑、垫片的安装以及灌浆；本发明能够实现抽水蓄能电站高压水道竖井等结构的快速安全衬砌目的，在保障高压水道整个生命周期内安全的同时，加快高压水道的建设速度。
