Arrangement method and structure of high-slope tailrace tunnel exit bulkhead gates
The invention discloses an arrangement method and structure of high-slope tailrace tunnel exit bulkhead gates. The center lines of gate grooves of one set of bulkhead gates at a tailrace tunnel exit and the center line of a tailrace tunnel are perpendicularly or obliquely arranged. When all the center lines of the gate grooves of one set of bulkhead gates coincide with a horizontal straight line A, a one-way gantry crane operation is adopted for the bulkhead gates, and when the center lines of the gate grooves of one set of bulkhead gates coincide with horizontal straight lines A and B correspondingly, two-way gantry crane operation is adopted for the bulkhead gates. A pair of gantry crane rails parallel to the center lines of the gate grooves is arranged on tailrace maintenance platformson the two sides of the gate grooves, gate chambers are arranged in the positions, between the two gantry crane rails, of the tailrace maintenance platforms, and the bulkhead gates are stored in the gate chambers and are protected by cover plates at ordinary times. A cave is dug in the position, at the ends of the gantry crane rails, of a mountain, and a gantry crane is stored in the cave at ordinary times. Through the arrangement method and structure, damage to the gates, open-close equipment and the like due to rolling stones and the like is avoided well, and storage safety of the high-slopetailrace tunnel exit bulkhead gates and the open-close equipment is improved effectively.
本发明公开了一种高边坡尾水洞出口检修闸门的布置方法及结构，本发明的尾水洞出口的一组检修闸门的门槽中心线与尾水洞中心线垂直或倾斜设置，当一组检修闸门的门槽中心线均与A水平直线重合时，检修闸门采用单向门机操作，当一组检修闸门的门槽中心线分别与A和B水平直线重合时，检修闸门采用双向门机操作；在门槽两侧的尾水检修平台上设置平行于门槽中心线的一对门机轨道，在两条门机轨道之间的尾水检修平台上设置门库，检修闸门平时存放在门库内并用盖板防护；在门机轨道端头的山体开挖山洞，门机平时存放于山洞内。本发明较好的躲避了滚石等对闸门及启闭设备等的破坏，有效提高了高边坡尾水洞出口检修闸门及启闭设备存放的安全性。
